NEC LCD Technologies develops white LED-based LCD module

TOKYO, JAPAN & SANTA CLARA, USA: NEC LCD Technologies, and its sales and marketing channel in the Americas, NEC Electronics America, Inc., announced the development of a new amorphous-silicon color TFT-LCD module that achieves an ultra-wide color gamut for 100 percent of the Adobe RGB color range by incorporating a newly developed LED light-source unit into the backlight system and a newly developed color filter.

The white LED that serves as the light source for the backlight unit in this LCD module achieves its white light by mixing light generated through the irradiation of red, green, and blue (RGB) phosphors with light from a near-ultraviolet LED chip (excitation), making it superior to traditional white LEDs in terms of color-rendering properties.

Combining these newly developed white LEDs with newly developed color filters, optimized for this application, makes it possible to reproduce a wider range of colors covering 100 percent of the Adobe® RGB color range, which is generally beyond the reach of conventional standard white LEDs.

In recent years, there has been an increase in customer demand for LCD displays using white LEDs as light sources in backlight units due to the many benefits achieved with LED backlight systems versus cold-cathode-fluorescent-(CCFLs)-based backlights. Such benefits include smaller module dimensions, lighter-weight designs, and reduced power consumption.

The LEDs are also mercury free and do not require the use of high-voltage circuitry, allaying concerns related to safety and the generation of harmonic currents and high-frequency noise. The LEDs offer superior vibration and shock resistance as well as superior characteristics with respect to low-temperature startup and a wider dimming range.

The white LEDs currently in widespread use typically have weaker output in their red and green wavelength components than CCFLs, since they create white light by exciting the yellow phosphors that cover the blue LED chips. For this reason, when used as backlight light sources, traditional white LEDs, even when combined with color filters having a wide color gamut, impose limits on the expansion of the red and green color reproduction range, making it difficult to cover the Adobe® RGB color range.

NEC LCD Technologies overcame these problems with its newly developed LCD module that is compatible with applications requiring an ultra-wide color gamut, a capability difficult to achieve with traditional white LEDs.

mPhase 3D rendering of superhydrophobic silicon membrane for smart NanoBattery

LITTLE FALLS, USA: mPhase Technologies Inc. released a 3D rendering of its superhydrophobic silicon separator that is a key element in the Smart NanoBattery architecture.

The membrane design is based on a porous silicon material that has a similar appearance to a honeycomb. This unique proprietary design prevents the battery's liquid electrolyte from coming in contact with the electrodes until power is needed, creating an unparalleled battery design. This process gives the user of the Smart NanoBattery Power on Command, a unique differentiator from other battery designs.

The first version of the Smart NanoBattery is made up of 12 individual cells that are essentially individual batteries assembled into one battery package. The cells are arranged in a 4x3 matrix inside the Smart NanoBattery fixture, each of which include all of the elements to act as an independent battery.

To illustrate the extremely small or "micro" size of honeycomb pores, each cell contains approximately 17,000 pores that are much smaller than a human hair. One Smart NanoBattery with 12 cells contains approximately 204,000 pores in a package about the size of a matchbook. The ability to selectively control the activation of each individual cell has never before been accomplished in battery technology.

"The ability to control the liquid electrolyte atop of this honeycombed structured surface is an incredible accomplishment that we are extremely proud of," said mPhase CEO Ron Durando.

OSRAM Opto focuses on energy-saving LED lighting solutions

SUNNYVALE, USA: OSRAM Opto Semiconductors is a subsidiary of OSRAM, one of the two leading lighting manufacturers in the world. The semiconductor company’s strategy is summarized by its mission statement: “We shape the future of light –- with advanced solutions for illumination, visualization and sensing.”

As a leader in the initiative to deliver more eco-friendly lighting solutions, OSRAM Opto Semiconductors continually develops and delivers new, highly efficient light sources (LED and OLED) for today and tomorrow. These new technologies will play a significant role in reducing the amount of electricity used for lighting as a proportion of total energy consumption.

LEDs: Light of the future
At present, energy savings based on conventional lighting technologies include compact fluorescent lamps (CFLs) with integrated electronics, advanced linear fluorescent lamps, halogen energy-saving lamps (HES) and high-intensity discharge lamps, together with advanced control gear and light management systems.

As the adoption of these more energy efficient light sources becomes more widespread in the coming years, the resulting energy savings will naturally increase.

In terms of technology, economics and politics, the current conditions are ideal for a paradigm shift to LEDs. Light emitting diodes have considerable potential for increases in brightness and efficiency, and can deliver even more potential energy savings than traditional light sources. Development work is ongoing and light emitting diodes are already penetrating the general illumination sector.

LEDs, called “the light of the future” by industry experts, are among the most energy-efficient light sources available today. LEDs can be five times more efficient than incandescent lamps, and are expected to be ten times more efficient in the future. LEDs are point light sources, and their directional light helps reduce light pollution, eliminating scattered, wasted light and delivering light precisely where it’s needed.

With artificial lighting accounting for approximately 19 percent of global electricity consumption (2.4 percent of primary energy consumption worldwide), replacing conventional light sources with efficient light sources such as LEDs could cut global electricity consumption for lighting in half.

Investing in eco-friendly solutions
OSRAM Opto Semiconductors is continually investing in research & development and has established a wide-ranging scientific network for the development and production of eco-friendly lighting solutions.

In 2008, OSRAM launched a project at Lake Victoria in Kenya involving rechargeable batteries, solar power and energy-saving lamps. As this concept is developed further, it will be possible to use optical semiconductors to create even more efficient off-grid solutions.

For years, OSRAM has operated certified environmental management systems and complied with the relevant standards at all of its sites worldwide. This applies more and more in many areas of production, the selection of raw materials, purchasing and health & safety.

The company’s environmental management system meets the requirements of ISO 14001:2004 (the international standard for such systems, at all sites), and ensures compliance and continual improvement. This covers not only the technologies for chips and associated products but also the use of energy and resources.

When OSRAM expanded its headquarters in Regensburg, Germany –- site of the world’s most advanced optical chip fabrication plant -– it constructed new facilities and launched an energy program based on making the best use of heat, reusing waste heat and reducing the generation of new heat to the absolute minimum.

The heat generated in the fabrication process is reused (compressed air, process cooling water), and the use of solvents such as acetone has also been reduced. To date, through these initiatives alone, OSRAM has eliminated nearly 5.2 tons of CO2 emission each year.

Looking ahead
LEDs are already being used in an extremely wide range of applications. They are more than just “nice to have” and there is ample evidence that cost efficiency and environmental protection are not mutually exclusive. LEDs combine sustainability with cost efficiency.

Double-figure growth is forecast for the LED market in the mid-term. As the technical performance of LEDs increases and their manufacturing costs decrease, LEDs will come to dominate more and more applications for which they offer significant energy savings and reduced overall costs. These applications include consumer electronics, automobiles, public sector/street lighting and solar energy applications.

Automotive relays to reach around 2.3bn units in 2009

BEIJING, CHINA:, one of China's leading B2B search platforms with more than 30 B2B industry websites to its name, discusses the auto relay market demand.

Relays are a major electronic automotive component, and their application volume in the automobile is inferior only to electronic sensors. Car comfort and safety's continuous improvement will inevitably lead to demand for automotive relays rising.

Relays are an important electronic automotive component; they are widely used to control vehicle starters, pre-heating, air conditioning, lighting, fuel pumps, anti-theft devices, audio, communications, navigation, electric fans, cooling fans, electric windows, airbags, ABS, various instrumentation and the fault diagnosis system.

Their application in the automotive industry is second only to automotive electronic sensors. As people increase their requirements for car comfort in recent years, the usage for automotive relays has shown a rapid upward trend.

In recent years, as automotive electronics, electrical products and automotive relays have also been developing by leaps and bounds, the world's automobile production and sales of relays have seen an upward trend.

It is expected that over the next few years, automotive electronics will continue to enhance their level and the automotive industry's demand for automotive electronic and electrical appliances will also be increasing.

Automotive relays can be roughly divided into two categories: automotive relays and plug-in PCBs (printed circuit board). The plug-in vehicle assembly in the central control box with wiring harness is easy to install and replace. PCB relays do more for automotive electronics modules. Compared to plug-ins, it is smaller and has a lower cost. Market demand for automotive products, relays and developing miniaturization grows.'s analyst forecasts that the global demand for automotive relays in 2009 will reach around 2.3 billion units with the PCB automotive relay carrying about 55% of the share. As people gradually improve requirements for car comfort, the proportion will continue to increase.

At the same time, automotive consumers will demand more safety, comfort, entertainment and other ever-increasing requirements that car designers will have to improve or redesign through the existing automotive electronics and electronic circuit modules, creating new performance requirements for PCB relays.

LED market development in China

BEIJING, CHINA:, one of China's leading B2B search platforms with more than 30 B2B industry websites to its name, analyzes the development of the LED market in China.

Amid uncertainties of economic recovery in the half-half of 2009, consumer demand was not strong, and demand of end-consumers for electronic products also remained still weak. However,'s analyst estimated that the LED industry in 2009 would sustain a positive growth driven by the growth in LED laptops market, as the penetration rate speeds up.

Facing uncertain market prospects, the analyst believes that LED industry, which has energy-saving advantages, will become a core industry this year; there is huge market potential for LED lamps, outdoor display screen and LED backlight modules fields.

LED can achieve high-light conversion efficiency, and with less power consumption, along with its small size, light weight, long life, non-mercury, non-radiation environmental protection advantages, coupled with a wide range of applications, including partial lighting, backlight panel, buildings (landscape) lighting, traffic lighting, medical and light source, such as agriculture, fisheries and animal husbandry equipment, it becomes a manufacturers' favorite.

There is a vast market for LED street lamps in 2009, amounting to 2.5 million calixs, with an annual growth rate of 178 percent. However, for LED lighting to officially enter the mainstream, the cost is the biggest obstacle. Manufacturers need to lower the cost of LED lamps in the long run in order to stay competitive.

The growing popularity of LED lighting has become an irreversible trend, and LED manufacturers are starting to explore more features to develop niche markets. Import is an obvious choice and the focus will turn gradually to the general lighting applications market.

Apac ODMs to expand into other commoditized markets to offset slowdown

DUBLIN, IRELAND: Research and Markets has added Frost & Sullivan's new report "Strategic Assessment of the Asia Pacific Original Design Manufacturing (ODM) Markets" to its offering.

This research provides an analysis on the Asia Pacific Original Design Manufacturing (ODM) markets. It discusses the key industry challenges, market drivers, and restraints. In addition, qualitative as well as quantitative analysis of the market trends and competitive structure are also provided.

Frost & Sullivan's report provides insights into the Asia Pacific ODM industry. The expert analyses key industry challenges, market drivers, and restraints. The market share by tier and strategic conclusion are also provided. Adept analysts thoroughly examine the following markets: data communications, telecommunications, and consumer electronics.

Market overview
The Asia Pacific ODM markets have traditionally succeeded in commoditized market segments where the electronic components used to design products such as notebooks, computers, and motherboards are easy to procure. The market's focus on the computing segment is further reinforced due to its vertically disintegrated value chain.

However, saturation levels and declining margins have begun to set in these segments. "The economic slowdown of industrialized countries and rising inflation are making the demand for notebooks, motherboards, and other consumer electronics unpredictable," notes the analyst. "Many ODMs are unable to forecast the demand for their products, fearing the risk of overcapacity and excess in inventories, which will eventually affect their revenues and operating margins."

Difficult market conditions are compelling ODMs to keep innovating in their existing saturated markets and expand in other commoditized markets such as mobile handsets and liquid crystal display (LCD) TVs.

"Adoption of a focused strategy, while continuing to make operational enhancements in IT systems and business processes, will go a long way in improving the ODMs business in the long term," says the analyst.

Since the ODM model was considered profitable, the OEMs compelled ODM vendors to lower costs. In fact, the success of the ODM model has prompted other market participants in the electronics manufacturing services (EMS) value chain to rapidly adopt it.

"ODMs must also understand the factors that enable the rapid migration of EMS providers to the ODM model," says the analyst. "The migration could be triggered by the EMS provider's ability to manufacture products at lower cost and more efficiently than ODMs, and the advantages of having global footprint as well as stronger IP protection."

Power Integrations achieves 92pc efficient power supply for LED streetlights

SAN JOSE, USA: Power Integrations, a leader in high-voltage integrated circuits for energy-efficient power conversion, has released a new engineering report (DER-212) describing a 92 percent-efficient power supply for LED streetlight applications.

The design utilizes Power Integrations’ HiperPLC power supply controller, which enables a simple, cost-effective circuit design by combining power factor correction (PFC) and resonant (LLC) control functions on a single integrated circuit. The new design will be showcased in the Power Integrations booth at LED Expo Korea (Kintex, Korea; May 20-23) and LED Lighting Taiwan (Taipei, Taiwan; June 10-12).

LEDs are rapidly emerging as the preferred streetlighting technology, displacing traditional technologies such as high pressure sodium (HPS) lamps. LEDs consume far less electricity for each lumen of useful light emitted, delivering as many as 80 lumens per watt when driven by a high-efficiency resonant power supply, versus just 58 lumens per watt for HPS lamps.

In addition, LEDs provide better directional control and color quality than HPS lights, an important consideration in shopping and residential areas. LEDs can also turn on and off instantly and retain their efficiency when dimmed -– features well suited to automated sensing of ambient light and human activity, allowing light output to be optimized for cost, with minimal consequences to the community lighting scheme.

Maintenance costs, and therefore the total cost of ownership, are also significantly reduced due to the intrinsically high reliability of LEDs compared to HPS lamps.

HiperPLC, Power Integrations’ first high-power product, is designed to control AC-DC converters from 80 to 600 watts. HiperPLC minimizes costs by reducing the size of the PFC magnetics required, and by combining the PFC and LLC controllers into a single IC. The IC provides up to 0.99 power factor and features synchronization of PFC and LLC controllers.

Synchronization reduces the ripple in the bulk capacitors, which reduces capacitor operating temperature and significantly extends the life of the power supply. Support for HiperPLC is now featured in Power Integrations’ PI Expert software (version 7.1.4), an automated power supply design tool based on PI products.

Doug Bailey, Power Integrations’ vice president of marketing, said: "Municipalities around the world are finding that LEDs offer a greener, more economical approach to streetlighting by saving both energy and maintenance costs. However, these benefits cannot be fully realized without a highly efficient, reliable power supply driving the LEDs. With HiperPLC, designers can produce a simple, reliable, cost-effective, power supply with efficiency as high as 92 percent."

OAS's unique technology prevents silver tarnishing

OXFORD, UK: Oxford Advanced Surfaces Group Plc, the advanced materials company, has developed a 1nm thick, environmentally friendly Onto coating that acts to protect silver against tarnishing.

The effect of atmospheric pollutants on the surface of exposed metals can result in the formation of a number of unwanted compounds causing tarnishing of the surface.

“Tarnishing is not just aesthetically unpleasant –- it also degrades the electronic and optical properties of the metal surface, and is therefore a causal factor in the reliability of LEDs, lighting, Printed circuit boards (pcb) and electronic components”, commented Mike Edwards, VP Sales & Marketing at OAS.

Current technologies addressing this problem have many disadvantages or are uneconomical, preventing wide scale implementation, particularly in electronic applications. The Onto coating doesn’t impede electrical connectivity, is thermally stable up to 250°C and is applied via a simple wet coating approach offering attractive solutions to a number of problems in the electronics and lighting industries.

Potential applications include industrial, household and automotive lighting systems, silver conductors throughout the electronics industry and other applications where silver or other valuable metals need to be protected from tarnishing. The company is seeking new partners for either tailored development or straight license of the silver anti-tarnish technology for use in their products and processes.

OAS develops and commercialises advanced material solutions which are cost effective, simple to implement, and deliver valuable changes to the functionality of all kinds of surfaces via our platform surface modification technology.

OAS uses proprietary highly reactive chemistry, Onto, in combination with polymers and/or particles to provide solutions that deliver enhanced performance which enables new, highly cost-effective opportunities. Initial applications include advanced adhesion, anti-tarnishing of silver, anti-reflectance coatings and particle delivery in markets including advanced composites and laminates, lighting, displays and FMCGs.

Riot of color in compact package for large video screens

SUNNYVALE, USA: OSRAM Opto Semiconductors has developed the smallest member of the RGB Multi ChipLED family to bring a new dimension of high-definition picture quality to large full-color video screens.

The Multi ChipLED enables high-resolution full-color video screens –- for example, in television studios, modern conference rooms, trade fairs and concert halls –- to offer brilliant colors and high contrast from all viewing angles. The tiny dimensions of this Multi ChipLED allow a very large number of pixels to be accommodated in a small display area. Housed in a black package that is mostly impervious to ambient light, the LED emits light in brilliant colors with excellent contrast.

OSRAM’s RGB Multi ChipLEDs are housed in a miniature package with dimensions of only 1.6 mm x 1.6 mm and measure just 0.9 mm high. With the RGB Multi ChipLED, it is possible to have a pixel spacing of only 2 mm, meaning that a great many pixels can be generated in a very small area. For example, an area of less than 10 m² is sufficient to display pictures in HDTV quality and accommodate more than 2 million pixels. A 2.5 x 4.0 m (98” x 157”) display 10 m (394”) in diagonal can achieve a system luminance of 1500-2500 cd/m², corresponding to around ten times the luminance of a conventional LED-backlit TFT LCD screen.

Perfect color mixing takes place in the Multi ChipLED package itself thanks to the specially developed encapsulation material. Color appearance remains constant across the entire viewing angle, and the picture appears vibrant even when viewed off-axis. The beam angle of the LED is +/- 60°. Ambient light cannot ruin the picture quality because it is barely reflected at all by the black package in which the LED is housed.

Inside the Multi ChipLED, there is a red chip, blue chip and a green chip fabricated using OSRAM’s ThinFilm and ThinGaN technology. If the RGB-LED is operated with a current of 20 mA, the individual chips produce typical luminous intensities of 250 mcd (red), 350 mcd (green) and 70 mcd (blue). The typical efficiency of this luminous intensity is 4 cd/W, which corresponds to a luminous efficacy of 12 lm/W.

White record OLEDs of Dresden Univ. and Novaled surpass efficiency of fluorescent tubes

DRESDEN, GERMANY: White organic light-emitting diodes (OLEDs) are a promising new technology to become the next generation light source. They have the potential of much higher efficiencies than classical lighting sources. Due to their unique features and attractive appearance white OLEDs will have a striking impact on the lighting industry.

These ultra-thin large-area-emitting devices can be flexible, transparent, color-tunable and scaled to virtually any size or shape enabling completely new ways for lighting designers. In terms of power efficiency, fluorescent tubes are a benchmark for emerging technologies with some 50-70 lm/W (considering losses in reflectors).

With the latest OLED record values of the Dresden University of Technology and Novaled AG closely cooperating in this project, this benchmark was clearly surpassed.

“In our approach, we combine a novel, very energy efficient emission layer design with improved light outcoupling concepts, leading to this breakthrough” says project leader Sebastian Reineke, Physicist at Institute of Applied Photophysics (IAPP, TU Dresden).

“The power efficiencies of the record devices reach 90 lm/W even if only flat, scalable outcoupling techniques are used. With special 3D outcoupling measures, even 124 lm/W have been achieved.” Both values were determined in an integrating sphere with blocked substrate edges, only taking the light into account that is emitted to the forward hemisphere, CIE color coordinates are (0.41/0.49). An in depth article is published in today’s highly esteemed research journal ‘nature’.

“The potential of the devices is obvious when one considers that even at the very high brightness of 5,000 cd/m2 a power efficiency of 74 lm/W is obtained,” comments Prof. Karl Leo, Director of IAPP. “Thus high-intensity illuminations at very high efficiencies are possible as well”.

“These results are at R&D level and further developments need to be made, e.g., for reaching commercially acceptable lifetime”, says Gildas Sorin, CEO of Novaled AG. “However, the values clearly indicate a major breakthrough and qualify OLEDs for mainstream lighting applications. The Novaled PIN OLED® technology is crucial, especially for combining high efficiencies with high-brightness data.

White OLEDs soon will help to reduce our carbon footprint and the Novaled doping technology will play a key role in this development”, adds Sorin.

RFMD expands broadband transmission product portfolio

GREENSBORO, USA: RF Micro Devices Inc. announced the addition of two new products to its extensive portfolio of broadband transmission products. The two newly released products are RFMD's D10040300GTH hybrid power doubler amplifier module and OS10040320PW optical receiver module. Both are designed for current- and next-generation CATV infrastructure applications.

The D10040300GTH hybrid power doubler amplifier module is specifically designed for CATV infrastructure applications including line amplification and hybrid fiber coaxial (HFC) optical nodes. The D10040300GTH operates from 40MHz to 1 GHz while typically maintaining 30dB or better of gain across the entire frequency range -- an industry first among available power doublers. The D10040300GTH helps cable operators to upgrade existing distribution networks to 1GHz and enables bandwidth-intensive services such as high-speed data, voice and HDTV. Operators can also exploit the linearity of the device to reduce the number of amplifiers in the network.

The OS10040320PW is a 1GHz hybrid high dynamic range optical receiver module designed for use in HFC optical nodes and deep fiber network installations. The OS10040320PW contains a single-mode optical input suitable for wavelengths from 1290nm to 1600nm, a terminal for monitoring the PIN diode current and an electrical output with an impedance of 75 Ohms.

The equivalent input noise current (EINC) performance of the OS10040320PW is among the industry's lowest at 5 pico Amps per root Hertz, typical performance, helping cable operators to implement "fiber deep" solutions as they upgrade to 1GHz networks. Specifically, by enabling the optical node portion of HFC networks to be placed deeper into CATV networks, the OS10040320PW minimizes requirements for more costly Erbium-doped fiber amplifiers (EDFAs).

Alastair Upton, general manager of RFMD's Broadband Components business unit, said, "RFMD® is pleased to support multiple system operators (MSOs) and their infrastructure equipment providers with innovative new products such as the D10040300GTH and OS10040320PW. As MSOs continue to upgrade their CATV infrastructure to 1GHz and implement fiber deep programs, these new products help to lower overall upgrade costs and enhance system performance."

ST innovates high-voltage transistor technology

SINGAPORE: STMicroelectronics has introduced a new family of power MOSFETs combining higher voltage capability, greater ruggedness, and lower losses than previous devices, which are well suited for use in high-efficiency power supplies for products such as LCD monitors, televisions and energy-saving lamp ballasts.

The STx7N95K3 family introduces a new 950V breakdown-voltage class for power MOSFETs. This new class benefits systems that minimize energy losses by operating at high voltages such as 400V or more. Compared to competing 900V devices, ST’s new 950V power MOSFETs have a larger safe-operating area delivering greater reliability.

Designers can also use a single 950V MOSFET to replace two-transistor circuits sometimes used to build high-voltage supplies, simplifying design, reducing size and lowering component count.

In addition, the STx7N95K3 family has a higher avalanche current rating than competing devices, which ensures greater resilience to surges above the breakdown voltage which cause the device to avalanche. The avalanche-current rating of 9A compares with around 1A for the nearest competing 900V devices.

As well as withstanding higher applied voltages, the STx7N95K3 family also minimizes conduction losses by achieving RDS(ON) of less than 1.35 Ohm. This represents a 30 percent reduction in RDS(ON) per device size compared to previous-generation MOSFETs, and allows designers to increase power density as well as improve efficiency.

At the same time, these new MOSFETs also deliver high switching performance by achieving low gate charge (QG) and low intrinsic capacitance, which allow designers to use higher switching frequencies, enabling the use of smaller components to further enhance efficiency and power density.

STx7N95K3 MOSFETs achieve these performance advantages by using ST’s latest-generation SuperMESH3™ technology. The devices introduced are offered in industry-standard packages including the STF7N95K3 in the TO-220FP package, the STP7N95K3 in standard TO-220, and the STW7N95K3 in TO-247.

The next available devices will be the 950V BVDSS STW25N95K3, STP13N95K3, STD5N95K3 and 1200V BVDSS STP6N120K3. ST will follow these devices with further new product introductions in 2009, including 850V, 950V, 1050V and 1200V ranges.

The STx7N95K3 family is in production, priced at $2.00 in quantities of 1,000 pieces.

Klipsch sells Aragon and Acurus brands to Indy Audio Labs

INDIANAPOLIS, USA: Klipsch purchased selected assets of the privately held Mondial Designs Ltd. in 2001, acquiring the Aragon and Acurus brands of high-end amplifiers, preamplifiers and processors. Now, the leading global manufacturer of loudspeakers is selling the rights to these electronics brands to two former Klipsch employees.

According to Mike Klipsch, president of the Klipsch brand, Klipsch purchased the brands because, at the time, it was aggressively seeking new ways to enhance its sound experience and wanted to develop perfectly matched, electronic solutions under the Aragon name.

However, a few years in, the electronics market underwent significant changes and Klipsch decided to cease production of the Aragon line in 2005, while still honoring warranty terms and offering customer support. “From that point on, we decided our product development and engineering teams needed to be completely focused on what we do best and that’s building high-performance loudspeakers,” he noted.

Today, the discontinuation of Aragon has opened new doors for former Klipsch electronics engineers Rick Santiago and Ted Moore. These two industry veterans, with 36 years of experience combined, have co-founded a new independent startup company called Indy Audio Labs, LLC and plan on developing and marketing new products under the Aragon and Acurus names. Indy Audio Labs will also assume full responsibility for the ongoing service and support of existing Aragon and Acurus products.

According to Santiago, IAL CEO, we are living in a time when traditional home entertainment experiences are being significantly re-defined and enhanced. “In our opinion, few manufacturers have been successful at providing the A/V realism and operational simplicity that consumers want, especially in this new digital media world. Indy Audio Labs is excited about developing future-ready entertainment products that exemplify the high-performance, reliability and ease-of operation of the classic Aragon and Acurus models,” he concluded.

Effective May 18, when people call the Aragon tech support line at (866) 781-7284 or the Aragon service line at (914) 693-8008, they will automatically be forwarded to Indy Audio Labs. Additional support information can be found at

“Rick and Ted are extremely passionate individuals and have a very forward-looking vision for these two highly regarded electronics brands. I can’t wait to see what’s next for Aragon and Acurus,” concluded Klipsch.

Growing consumption of electronic goods to benefit crystal oscillator makers

NEW YORK, USA: The markets for crystals and crystal oscillators will more than double during the next five years due to the increasing demand worldwide for high-end consumer electronic goods and wireless devices, according to a new study from Visant Strategies.

Revenues for crystals will grow from $3.1 billion in 2008 to $4.3 billion in 2013 while the world market for crystal oscillators will almost double during the same timeframe, according to the report.

"We see a small shift from telecommunications to consumer electronics and home entertainment devices as the intended end application for crystals and crystal oscillators and likewise, the Asia-Pacific nations will see its leading consumption of crystals and crystal oscillators grow," said Kaustubha Parkhi, author of "Crystal Oscillators 2008: The Decade Ahead."

While use in telecommunications devices continues as the largest application for crystal oscillators, accounting for more than half of all shipments in 2008, this share will drop slightly during the next five years, according to the report.

"Most of this loss will be gained by the consumer electronics and entertainment segment, a category in which shipments will grow by fifty percent through the next five years," Parkhi said.

The Asia-Pacific region will reign as the major consumer and producer of crystals, responsible for more than half of the world consumption, the report finds. North America will lose market share in production of crystal oscillators annually during the next five years, the report states.

"Crystal Oscillators 2008: The Decade Ahead" assesses the markets for crystals and crystal-based oscillators. World shipments and revenues are provided for each product type: crystals, uncompensated crystal oscillators (XO), temperature compensated crystal oscillators (TCXO), voltage controlled crystal oscillators (VCXO), and oven controlled crystal oscillators (OCXO).

Product types are further broken down by application, stability, regional output and consumption, output frequency ranges and packaging techniques. Crystal oscillators are also broken down according to output waveform types. Key end use and design trends are considered for each product type with examples given.

Handsfree car kits not truly handsfree!

USA: Strategy Analytics' Wireless Device Lab service research, “HandsFree Car Kits: Consumers Lack a Truly HandsFree Experience", shows that purchasers of after market car kits in the UK would like to use speech recognition in order to make their car kit experience truly hands-free; but speech recognition systems fall short of expectations.

These findings are based on in-depth one-on-one research sessions with participants near London, England.

“Strategy Analytics research shows that consumers would like their car kits to provide easy and intuitive handsfree methods for dialing and answering their cell phones while driving,” commented Chris Schreiner, Senior User Experience Analyst at Strategy Analytics. “However, consumers struggle with speech recognition due to usability issues.”

Kevin Nolan, Vice President of the Strategy Analytics User Experience Practice, added, "Our research also shows that streaming music is a service in some car kits that adds value for the consumer, although consumers prefer to experience music via direct hookup through their vehicle speakers rather than via an FM transmitter.”

ST, Front Edge to bring next-gen battery technology to new markets

SINGAPORE: STMicroelectronics announced a commercial agreement with Front-Edge Technology (FET), the California-based developer of next-generation rechargeable batteries, enabling ST to bring FET’s NanoEnergy ultra-thin lithium battery technology to a wide range of new markets and applications.

This new technology is meant to fill the gap created by conventional energy-storage devices not keeping pace with the demanding size and high-density power requirements of today’s cutting-edge electronic devices. The new devices, which are destined for consumer and industrial markets, demand innovative energy-storage and battery technologies.

Solid-state thin-film energy cells offer a revolutionary way of storing energy for ‘micro-power’ devices, such as high-end ‘One-Time-Password’ smartcards; battery-assisted RFID tags; wireless sensor networks; real-time clock (RTC) back-up batteries; and multiple medical applications, including hearing aids, automatic insulin pumps and wearable health monitoring systems.

A key advantage of the ultra-thin solid-state battery technology is its physical flexibility, enabling different sizes and shapes of ‘bendable’ batteries, as thin as 200 microns, making it ideal for portable and extremely small form factor devices. Additionally, the battery’s solid electrolyte is Lithium Phosphorus Oxynitride (LiPON), a material originally developed by Oak Ridge National Laboratories. This enables the thin-film FET technology, in comparison with a device with equivalent energy storage capacity, to deliver in the range of 10 to 20 times more power than existing state-of-the-art coin-cell batteries.

FET’s solid-state micro-batteries have been shown to offer longer life, short-circuit prevention for greater safety, and a lower environmental burden than existing battery technologies. Other key characteristics of the FET technology include long cycle life, with more than 1,000 cycles at 50 percent discharge; fast current charge enabling batteries to be charged to 80 percent of rated capacity within 15 minutes; and high stability, with a low self-discharge of less than 15 percent per year.

“There is large and growing gap between the increasingly fast pace of the proliferation and demands of today’s leading-edge portable electronic products and the capabilities of existing energy sources, in performance, operating life and environmental impact,” said Carmelo Papa, Executive Vice President and General Manager of ST’s Industrial and Multisegment Sector (IMS). “As one of the world’s largest and most innovative semiconductor companies, ST has the vision, breadth and market reach to bring FET’s revolutionary ultra-thin battery technology to new industrial and consumer applications.”

“Over the past 10 years, FET has developed NanoEnergy, the highest energy density thin-film battery technology in the industry, and three years ago we began commercially selling NanoEnergy batteries in small volumes,” said Dr. Simon Nieh, President of FET. “We are truly delighted to team up with one of the largest and most innovative global semiconductor companies to address new opportunities in industrial and consumer markets for thin-film batteries.”

ST, which has always been a leader in power technologies, is making significant investments in new energy technologies and nano-materials to develop new miniaturized solutions for energy storage and deliver with a particular emphasis on powering portable electronic products. The R&D group of ST’s Industrial and Multisegment Sector (IMS) organization has been working for several years developing know-how and expertise in the field of micro-batteries and micro fuel cells, and has research teams based in Tours, France, and Catania, Italy, working with research institutes in both those countries.

New class of light with OSRAM OSLON SSL LED

SUNNYVALE, USA: The new ultra-white OSLON SSL LED from OSRAM Opto Semiconductors may be small in size, at only 3 x 3 mm, but it’s big on performance. Using the latest chip technology, the 1 W OSLON SSL LED achieves impressive brightness and high luminous efficiency of 100 lm/W.

The OSLON SSL LED meets the required standard for general lighting usage and is reliably efficient even at high currents and thanks to its beam angle of 80° it is perfect for injecting light into external lenses. The OSLON SSL LED is ideal for spotlights, desk lights and ceiling floodlights

“Its ability to handle high currents efficiently enables our customers to create energy-efficient and cost-saving lighting solutions. The OSLON SSL LED has all the attributes to become the ‘green’ light source of the future,” said Brian Terao, Director of SSL at OSRAM Opto Semiconductors, Inc.

The OSLON SSL LED has a low thermal resistance of 7K/W, which simplifies thermal management. Its compact size gives designers the flexibility to create extremely sophisticated solutions and in designs where more light is needed, several OSLON SSL LEDs can be combined to form a cluster.

In addition to ultra-white (5700 to 6500 K), the LED will be available this summer in neutral white and warm white with a color temperature ranging from 2700 to 4500 K.

Manufactured with the latest chip technology, the OSLON SSL LED has an operating current of 350 Ma, which enables the light source to achieve a typical brightness of 110 lm in ultra-white (5700 and 6500 K), and a maximum possible luminous flux of 130 lm at present. At an operating current of 350 mA and a color temperature of 3000 K, the OSLON SSL LED can achieve efficiency of 75 lm/W and a brightness of 85 lm.

Additionally, brightness is a remarkable 155 lm at an operating current of 700 mA (warm white). At these performance levels, the OSLON SSL LED can meet the demand for high-lighting levels using fewer LEDs with currents up to 1A.

OSRAM intros LED solution for street lighting

SUNNYVALE, USA: The Golden DRAGON oval Plus LED from OSRAM Opto Semiconductors provides ideal illumination for energy-efficient street lighting without the need for secondary optics due to the new integrated lens. Its oval radiation pattern delivers directed light, ideal for street lighting, and its integrated lens significantly reduces the overall effort for this application.

Golden DRAGON oval Plus has been developed as an ‘easy-to-use’ LED solution specifically for street lighting applications. With its unique oval beam characteristics (80° vertical, 120° horizontal) and integrated long-life silicon lens, it provides energy-efficient street lighting with minimal light pollution. The light is directed precisely on the area to be illuminated with no upward stray light.

Since different roads call for different lighting environments, Golden DRAGON oval Plus LED is available in various white tones with an efficiency of 90 lm/W in cold white (6500 K color temperature) and 80 lm /W in neutral white (5000 K).

The warm white version with a color temperature between 2700 and 4500 is ideal for any lighting scenario where a warm and welcoming atmosphere is required, such as in a historic city center. At 4500 K it achieves an efficiency of 65 lm/W and produces an aesthetically pleasing warm white light.

The main feature of the Golden DRAGON oval Plus LED is its integrated lens. The lens makes secondary optics unnecessary, while enabling street lighting applications to be realized with much less effort, delivering unprecedented application efficiency from an LED component. The LED is also suitable for standard solder processes.

“Our new ‘street lighting LED’ combines various lighting benefits in one innovative package. It is highly efficient, and has a long lifetime due to its silicone lens. Additionally, it offers good visibility at night because the LEDs can be arranged in the system to distribute the light accurately delivering light where it is most needed. This new light source also makes it easier to upgrade current systems to more efficient street lighting with LED technology,” said Dr. Markus Klein, Head of SSL Product Development at OSRAM Opto Semiconductors.

The Golden DRAGON oval Plus is suitable for all applications that call for efficient lighting with a homogenous oval light pattern, particularly street and tunnel lighting. It meets all the requirements for homogenous illumination. The LEDs are also lead-free and mercury-free and therefore an ideal solution for the future of more energy efficient, environmentally friendly outdoor lighting.

MIC, TERI light rural villages and homes through high efficiency solar LED lighting systems and LED lanterns

MUMBAI, INDIA: MIC Electronics Ltd made an announcement today that the company would provide high efficiency solar LED Lighting Systems, to rural areas.

Dr. M.V. Ramana Rao, Managing Director of MIC, said: “We will supply high efficiency solar LED lighting products to light villages. Using the power of free and abundant sunlight, MIC’s solar LED lanterns are MIC’s green energy solutions that would replace the kerosene and paraffin lanterns in each household.”

Ms Akanksha Chaurey, LaBL’s Global Head and TERI’s Director for Decentralized Energy Solutions Division, unveiled MIC’s High Efficiency Solar Lighting Systems. Other than Solar LED Lighting Products developed by MIC Electronics and certified by the Ministry of New and Renewable Energy (MNRE), high light output 3W and 5W solar LED lanterns have been selected by TERI for LaBL program.

“Over 1.6 billion people in the world lack access to electricity and 25% of them live in India. For these people, life comes to a standstill after dusk. Inadequate lighting is not only an impediment to progress and development opportunities, but also has a direct impact on the health, environment, and safety of people who are forced to light their homes with kerosene lamps, dung cakes, firewood, and crop residue after sunset. LED lanterns are more efficient and long lasting than CFL Lanterns and MIC’s commitment to the cause of developing sustainable technologies for renewable energy source is laudable.” said Ms. Akanksha Chaurey.

The path breaking initiative of MIC Electronics and TERI is fully supported by NICHIA Corporation, Japan and Texas Instruments, USA.
Makoto Takenaka San of NICHIA Corp.

Through this campaign, local entrepreneur-driven delivery channels are created for distribution and servicing of solar lanterns to rural communities. The campaign also provides excellent opportunity for public-private-people-partnership (P4) wherein the private sector can enhance the effectiveness of development schemes of the government, particularly in health, education and livelihoods sectors, by providing lighting through LaBL.

Is there a life for bulk GaN substrate out of the blue laser diode business?

FRANCE: Yole Developpement has released a new market analysis dedicated to Bulk GaN. In this report, the French consulting company detailed the major market metrics of the current and projected bulk/free-standing GaN substrate business, with a focus on applications, key players, volumes and related market size of each segment.

Yole highlighted the possible total accessible market for GaN substrates, including the strengths and weaknesses of this technology over the current established epiwafer or ELO technologies. Yole’s described the recent progress in crystalline quality as well as the new challenges offered by non-polar and semi-polar GaN material.

From blue lasers to lighting and power electronics
Today, bulk or Free-Standing (FS) GaN substrate market is mostly driven by the blue laser diode production only and its related application in high-density data storage. This market is driven by strong demand for Bluray players and game stations.

From 2011 and most likely 2012, Ultra-High Brightness (UHB) LEDs will start taking part of the bulk-GaN production. “That will only be possible with a sharp drop in bulk-GaN prices. We forecast that the critical threshold is below $1,500 for a 2” “LED-grade” substrate”, explained Dr Philippe Roussel, Project Manager at Yole Développement. Only such a price level will act as leverage for LED market take-off.

2012-2013 will also see the introduction of new power devices based on bulk-GaN. Again, here, that is strongly linked to the pricing of bulk-GaN that will have to compete with 4” and future 6” SiC offer and GaN-on-Silicon alternate technology.

Lack of bulk material pushes for ELO technique
Market is now essentially centered on free-standing material. However, the shortage of this product has to be compensated by the use of home-made ELO-GaN on sapphire substrates. Yole Développement assumes about 28% of LD was made on ELO-GaN in 2008. This percentage will decrease a little but will stay significant by 2012.

Asia dominates the substrate business but EU and US exhibit credible challengers

The main free-standing producer remains Sumitomo, mostly supplying Nichia and Sony for laser production. Other challengers such as Hitachi-cable (now sampling 3” wafers) or Mitsubishi Chemical are becoming more and more present.

In Europe, LumiLOG, now part of Saint-Gobain group and the UK company, NanoGaN, is fine-tuning its product line-up for the LED illumination business; Ammono and TopGaN are improving their strong expertise in low dislocation density crystals.

The US region is mainly focusing on non or semi-polar material, with Kyma, Inlustra Technologies or Oxford Instruments (TDI).

By 2015, bulk GaN for LED will dominate the substrate market in volume

2” substrates production volume could reach about 100,000 units by 2010, leading to a relative $240M market for both free-standing and ELO. Beyond 2013, the growing demand for bulk GaN in LED lighting applications will rapidly dominates the market in volume.

IPC releases PCB industry results for March 2009

BANNOCKBURN, Ill., USA: IPC — Association Connecting Electronics Industries recently announced the March findings from its monthly North American Printed Circuit Board (PCB) Statistical Program.

PCB industry growth rates and Book-to-Bill ratios announced
Rigid PCB shipments are down 30.5 percent and bookings are down 39.8 percent in March 2009 from March 2008. Year to date, rigid PCB shipments are down 24.6 percent and bookings are down 35.6 percent. Compared to the previous month, rigid PCB shipments increased 9.6 percent and rigid bookings increased 10.5 percent. The book-to-bill ratio for the North American rigid PCB industry in March 2009 remained below parity but moved up slightly to 0.92.

Flexible circuit shipments in March 2009 are up 1.0 percent, and bookings are down 12.0 percent compared to March 2008. Year to date, flexible circuit shipments are up 6.0 percent and bookings are down 7.4 percent. Compared to the previous month, flexible circuit shipments are up 22.3 percent and flex bookings are up 15.0 percent. The North American flexible circuit book-to-bill ratio in March 2009 dropped to 0.87.

For rigid PCBs and flexible circuits combined, industry shipments in March 2009 decreased 28.3 percent from March 2008 and orders booked decreased 38.0 percent from March 2008. Year to date, combined industry shipments are down 22.7 percent and bookings are down 34.0 percent. Compared to the previous month, combined industry shipments for March 2009 are up 10.7 percent and bookings are up 10.9 percent. The combined (rigid and flex) industry book-to-bill ratio in March 2009 was 0.91.

“Sales and orders improved in March over the first two months of the year due to seasonal effects, but year-on-year growth in rigid PCBs is still down significantly,” said IPC President Denny McGuirk. “Orders are still lagging behind sales, which suggests that sales will continue to weaken for the next quarter.”

The book-to-bill ratios are calculated by dividing the value of orders booked over the past three months by the value of sales billed during the same period from companies in IPC’s survey sample. A ratio of more than 1.00 suggests that current demand is ahead of supply, which is a positive indicator for sales growth over the next two to three months.
