However, as an integrated supplier and service provider of LED optoelectronics, Absen has created a path-breaking revolution in LED marketing.

Why is Absen carrying out their Zero Down Payment policy? A down payment brings a risk to buyers, especially when they know little of the manufacturers. Paying a down payment in advance for products which have not yet been produced is a big challenge for clients. So checking products prior to payment will set buyers' minds at rest. In addition, Absen's 7-day quick shipping shortens the purchase period and saves clients' time, while Absen's 25 processes ensure high quality products.

Spot supply, so Zero Down Payment can come true
How can Absen offer Zero Down Payment? It is well-know that LEDs are the central component of LED signs. Absen produces LEDs on a large scale by itself. That effectively guarantees LED signs quality and a 3000 sqm regular production spot supply which ensures the "Zero Down Payment" policy. The main products include A1088, A1688 and AI06. They have superb cost effectiveness, visual effect comparable to theaters; dynamic contrast technology and excellent all-round monitoring and controlling of production process and 24-step quality control.

Spot supply can create the greatest value for clients in the shortest time. It satisfies most clients, but, if needed, Absen will not turn down "personalized customization". At present, Absen's integrated production lines and solid R&D ability, and a comprehensive range of high quality products, are the base for customized solutions.

Absen's Zero Down Payment is built on Absen's core values: "Honesty, Gratitude, Responsibility". It is bound to open a new age for the LED signs industry, and create more values for clients.

Market opps for OLED lightning worth $1.5 billion in Europe

GLEN ALLEN, USA: Industry analyst firm NanoMarkets has released its latest report titled, “OLED Lighting Markets Europe-2011,” that says the market opportunities in Europe for OLED lighting will generate $1.5 billion in OLED lighting panel sales by 2016. The report is the latest in NanoMarkets’ continuing coverage of the global OLED lighting marketplace.

NanoMarkets has also recently released reports on the market for OLED lighting in Asia and an update of the firm's global market forecast for OLED lighting. In addition, the firm has issued a report on the business case for OLED lighting and will soon issue a new report on the OLED materials market. An analysis and forecast of OLED lighting manufacturing capacity worldwide will be published by NanoMarkets in September of 2011.

Key findings
German markets and firms will be the largest factor in the European OLED lighting scene for the foreseeable future. According to NanoMarkets’ projections, Germany will account for one fourth of all OLED lighting sales during the 2011 to 2018 period. In addition, the OLED lighting manufacturing in Europe is concentrated in Germany which is home to major facilities operated by BASF, Fraunhofer IPMS, Philips, Heraeus, Osram, Ledon, Merck and Novaled. German OLED lighting panel sales will reach almost $360 million in OLED panel sales by 2016.

After Germany, the UK will generate the greatest revenues from OLED panel sales during the forecasting period covered by the report, with almost $210 million in revenues by 2016. The UK’s prominence in the OLED lighting field is driven by the relatively large size of the country and the fact that it started phasing out incandescent bulbs earlier than any other European nation. The UK is also home to some highly innovative OLED firms such as CDT, E2M, Lomox and PolyPhotonix.

European firms, including Blackbody, Osram and Philips, already dominate the worldwide market for OLED luminaires and will continue to do so. There are already as many as 20 luminaires produced by European firms; albeit in limited quantities. Reflecting Europe’s long-established strength in industrial design, many of these luminaires have been created by leading lighting and furniture designers such as Ingo Maurer and Tom Dixon.

Cree’s Z-FET silicon carbide MOSFET delivers superior energy efficiency to an expanding list of power apps

NUREMBURG, GERMANY: Providing power electronics design engineers with a way to increase the efficiency of high-volume power inverters for alternative energy and other power electronic applications, Cree Inc. has extended the product range of its industry-first Z-FET family with a lower amperage 1200V SiC MOSFET.

The new MOSFET device complements Cree’s existing 1200V SiC MOSFET and features a smaller current rating that enables the device to be included in a wider range of applications at a lower price point or used in parallel to optimize system cost and performance.

The new device is designed to replace the silicon transistors (IGBTs) that are currently used in power inverter designs between 3 and 10kW. Applications include high-voltage power supplies and auxiliary power electronics circuits, especially those designed for conversion of 3-phase input power, solar power inverters, industrial motor drives, high-power DC data center power architectures, and PFC (power factor correction) circuits.

“The addition of this new switching device to our Z-FET SiC power MOSFET family gives our customers a greater range of flexibility in matching the price/performance requirements to their applications,” said Dr. John Palmour, Cree co-founder and chief technology officer, Cree Power & RF.

“The smaller die size provides a lower price point, yet still delivers all the benefits of silicon carbide switching performance at 1200V. It’s further evidence that we’re committed to establishing a comprehensive range of SiC MOSFET products that we believe will eventually replace silicon devices in many high volume power electronics applications, especially those with 1200V and higher breakdown voltage requirements.”

“By using the new Z-FET SiC MOSFETs in conjunction with Cree’s silicon carbide Schottky diodes to implement ‘all-SiC’ versions of critical high power switching circuits and power systems, power electronics design engineers can achieve levels of energy efficiency, size and weight reduction that are not possible with any commercially available silicon power devices of comparable ratings,” Palmour explained.

Cree’s new SiC MOSFET is rated for 12A at its operating temperature of 100°C and delivers blocking voltages up to 1200V with a typical on-state resistance (RDS(ON)) of just 160mΩ at 25°C. Unlike comparably-rated silicon switching devices, Cree’s new SiC MOSFET exhibits an RDS(ON) value that remains below 200mΩ across its entire operating temperature range. This reduces switching losses in many applications by up to 50 percent, increasing overall system efficiencies up to 2 percent while operating at two to three times the switching frequencies when compared to the best silicon IGBTs.

As a result of this improved efficiency, SiC devices have lower operating temperatures and fewer thermal management requirements, which combine with their ultra-low leakage current (<1µA) to reduce system size and weight and increase reliability.

Diodes Inc.'s dual gate logic aids product miniaturization

PLANO, USA: Diodes Inc., a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, has announced its first series of dual gate logic devices, designed to help reduce component footprints in small handheld products, including tablet computers, smart phones and e-readers.

The 74LVC2G two-gate parts are provided in the miniature and robust DFN1010 package, measuring only 1mm square and with a maximum off-board height of 0.4mm.

Six dual gate logic devices have been initially introduced, comprising inverters and buffers each in a choice of simple, Schmitt trigger input and open drain types. The devices complement Diodes’ 74LVC1G family of 18 different single gate logic functions announced earlier in the year. It is planned that the dual gate logic parts will also be offered in SOT26, SOT353 and DFN1410 package alternatives.

The logic devices’ wide operating voltage range, of 1.65V through to 5.5V, means that they will readily support both portable battery operated as well as legacy 5V product design. By typically drawing less than 1µA the 74LVC2G logic will also be of benefit to the more energy sensitive applications.

When powered down, the dual gate logic’s output circuitry is disabled to prevent damaging backflow current and to ensure effective signal isolation. 5.5V tolerant inputs enable the parts to be employed as voltage translators.

Avago expands industry-leading optocoupler portfolio with new family for robust IGBT gate drive

SAN JOSE, USA & SINGAPORE: Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, announced a new generation of gate drive optocouplers that deliver industry-leading performance from a small-footprint package.

The new ACPL-P34x and ACPL-W34x optocoupler family is based on process technology that enables higher output current drive with rail-to-rail capability, providing high-voltage insulation and robust protection for industrial drive, inverter and power supply applications. The optocouplers are available in a stretched SO6 package that is 40 to 50 percent smaller than industry-standard Dual-inline (DIP) package. With output current up to 4A – the market’s highest in this package – the family provides reliable, fast and efficient system performance.

Traditionally, Avago gate drive optocouplers have used bipolar transistors for the output stage to deliver high output current. With process technology improvements, the output stage can now be replaced with bipolar CMOS/DMOS technology, which combines the high component density and low power consumption of CMOS with the high current drive and speed of bipolar process. The switching speed is also now twice as fast as the previous generation, reducing the dead time when both the high-side and low-side transistors are off from 700 ns to 200 ns for improved system efficiency.

“Avago continues to bring value to customers by setting new standards for optocoupler performance, as exemplified by our new gate drive family,” said Kheng-Jam Lee, marketing director for optocoupler products at Avago. “This innovative family expands our optocoupler portfolio, which is already the industry’s broadest, to better address a wider range of applications. This is especially important for motor drive and emerging renewable energy inverter applications, which are seeing tremendous growth in the use of IGBT.”

The ACPL-P343/W343, ACPL-P341/W341 and ACPL-P340/W340 optocouplers come in 4A, 3A and 1A maximum peak output current, respectively. The wide range of output current allows the family to address systems with different power ratings, including Insulated Gate Bipolar Transistor (IGBT) and MOSFET gate drive, industrial inverters, renewable energy inverters, AC and brushless DC motor drives, switching power supplies, induction cookers and inverters for home appliances.

The high common mode rejection (CMR) of the optocouplers, at 35 kV/µs prevents erroneous driving of an IGBT and ensures reliable operation in noisy environments. The family’s stretched SO6 packages are compliant to many industrial safety standards, including IEC/EN/DIN EN 60747-5-2, UL 1577 and CSA.

Novaled develops world's most power-efficient fluorescent white pin LEDs

DRESDEN, GERMANY: Novaled, a technology and materials provider specializing in high-efficiency, long-lifetime organic light-emitting diodes (OLEDs), today announced it has developed the world’s most power-efficient fluorescent white OLED structures – achieving 36 lumen per Watt (36lm/W).

Using its proprietary organic materials and a new flat light outcoupling method of extraction, Novaled increased OLED device light emission by more than 80-percent, with good color rendering, and also improved the angular dependence of the light emitted. Novaled’s new power-efficient fluorescent white PIN OLEDs result in lower manufacturing costs and meet the standards for commercial lighting applications, making them ideal for OLED lamps and luminaires for general and design lighting.

Thus, Novaled’s efficiency enhancements move OLED technology a step closer to becoming practical for widespread use in lighting applications for the mass market. Novaled will showcase its new technology in Booth #927-4 of the German Pavilion at the Society for Information Display’s (SID) annual International Symposium, Seminar & Exhibition, “Display Week 2011,” May 17-19, 2011, at the Los Angeles Convention Center, Los Angeles; it also will present two papers there on May 20, 2011, on its enhanced outcoupling methods and materials, and on materials for hybrid OLEDs in display applications.

Novaled CEO, Gildas Sorin, saud: "Until now, typical outcoupling methods have been somewhat ineffective or have resulted in rising manufacturing costs. Novaled has overcome both challenges – pioneering a novel way to significantly improve light outcoupling results and boost external quantum efficiency by more than 80 percent, without the costly and time-consuming setup traditionally required for complex manufacturing. Novaled is a well recognized materials provider for OLED and other organic electronic applications.

"We will continue to use our expertise to develop leading-edge solutions that help advance OLED technology toward widespread use for mass-manufactured lighting applications."

Effective outcoupling, better light quality
Novaled’s novel methods boost outcoupling effectiveness, substantially increasing the 25-35 percent fraction of generated light that typically leaves the OLED device for lighting applications. They also increase power efficiency and quantum efficiency in both bottom- and top-emission OLEDs. In bottom-emission OLEDs Novaled incorporates the material NET61 directly inside the electron transport layers.

The combination of NET61 internal outcoupling and an external micro lens array (MLA) film boosts power efficiency by more than 70-percent and quantum efficiency by more than 80-percent. In top-emission OLEDs, Novaled uses scattering material NLE17 on top of the semi-transparent top electrode to help extract light and improve the quality of light emitted from top-emission white OLED devices.

Novaled’s new outcoupling techniques use standard processes to produce the white PIN OLED device structures, thus reducing manufacturing costs for both bottom-emission and top-emission OLEDs. Unlike other outcoupling enhancement approaches in bottom-emission OLEDs – such as depositing complicated structured layers between substrate glass and the indium tin oxide (ITO) anode – Novaled uses simple internal outcoupling methods with vacuum evaporation processed organic materials to induce scattering of the light emitted by the OLED. In both bottom- and top-emission OLEDs, the scattering does not negatively impact electrical properties.

In addition, Novaled’s new method improves the Color Rendering Index (CRI) value for top-emission OLEDs on metal substrates. Although top-emission samples on metal substrates with a white light emission typically have stronger cavity effects than bottom-emission devices and show strong variations with the viewing angle, Novaled increases light extraction from top-emission white OLEDs and strongly reduces angular color dependence by using a scattering evaporation processed organic layer on top of the semi-transparent top electrode. Novaled’s demonstrated CRI of 75 for top-emission OLEDs is ample for many commercial lighting applications.

LED lamps create light by running an electrical current through a microchip. They are increasingly replacing light bulbs in both indoor and outdoor settings due to their higher energy efficiency and longer lifespans compared to traditional incandescent or compact fluorescent bulbs, while providing warm, pleasing light.

The Flexible Display Center and Universal Display produce flexible, full-color AMOLED prototype displays

TEMPE & EWING, USA: The Flexible Display Center (FDC) at Arizona State University and Universal Display Corp. announced that they have successfully fabricated the first full-color, flexible active matrix organic light emitting diode (AMOLED) display prototypes using the Center’s bond/de-bond manufacturing process, in combination with Universal Display’s full-color, top-emission phosphorescent OLED technology and materials.

The displays use Universal Display’s patented, proprietary single-layer encapsulation technology to seal the OLEDs made on DuPont Teijin Films Teonex polyester film. Successful fabrication of the displays involved incorporating materials and technologies concurrently developed by several additional members of the FDC’s 30-member industrial consortium.

Funded by the US Army, the FDC is developing the full-color, flexible OLED displays for use in thin, lightweight, bendable and unbreakable devices capable of displaying full-color full-motion video. The lower power consumption of Universal Display’s phosphorescent OLEDs compared to other full-color video display technologies is an important advantage for ultralight soldier-portable devices, and a range of OLED display products based on this technology are already in the marketplace.

A key enabler of the flexible displays announced is Universal Display’s recently introduced single-layer encapsulation technology that was designed for plastic substrate systems and thin-film devices, including flexible OLED displays. The encapsulation layer provides an effective barrier to protect thin film devices from environmental conditions, such as moisture and oxygen, which is critical for the long-term performance of OLED displays.

Using environmentally benign and non-toxic materials in a potentially low-cost process, the barrier film technology has demonstrated its suitability for high-performance, flexible plastic substrate systems in these new AMOLED displays.

“Demonstrating the first flexible color phosphorescent AMOLED display that integrates Universal Display’s encapsulation technology with the FDC’s bond/de-bond manufacturing process represents a tremendous step forward in the advancement of flexible OLED displays,” said Dr. Mike Hack, GM OLED Lighting and Custom Displays, VP of Universal Display and a member of the FDC Board of Governors. “In addition to working toward the targets set by the US Department of Defense, flexible OLEDs have the potential to open up a vast array of product opportunities in the commercial and consumer sectors in the foreseeable future.”

The displays are in a 3.8-inch diagonal QVGA format (320x240 pixels) and use Universal Display’s phosphorescent red, green and blue OLED materials, which have already been proven to significantly reduce power consumption in numerous glass-based AMOLED products.

The displays use an active matrix array of thin film transistors fabricated on DuPont Teijin Films Teonex film using substrate handling and processing technologies developed at the FDC. Versions using transistors made with both low-temperature amorphous silicon and higher performance indium-gallium-zinc-oxide have been produced.

“The combined effort with Universal Display and our other industry partners to successfully produce flexible, full-color AMOLED displays validates our bond/de-bond manufacturing technology,” said Nick Colaneri, director of the FDC.

“The display industry is actively evaluating a variety of approaches to handling flexible plastic substrates in conventional manufacturing equipment, which is a critical step towards enabling the mass production of flexible displays. The FDC’s bond/de-bond process with re-usable carriers adds minimal incremental cost, allows the use of a variety of high-performance plastic substrate materials, and has been proven up to Gen II scale at the FDC’s pilot line, making it a leading candidate production technique as flexible electronics continue to evolve.”

Cree 231 lumen per watt LED shatters efficacy records

DURHAM, USA: Cree Inc. reported another industry-best efficacy record of 231 lumens per watt for a white power LED. This result is a significant advance beyond Cree’s previous industry record and further demonstrates how Cree’s relentless innovation continues to push the boundaries of what is possible with LED lighting.

Cree reports that the LED efficacy was measured at 231 lumens per watt using a single-die component at a correlated color temperature of 4500 K. Standard room temperature 350 mA testing was used to achieve the results.

“It wasn’t long ago when 200 lumens per watt was considered the theoretical maximum efficiency for a lighting-class LED. We broke that barrier in 2010, and have now achieved 231 lumens per watt,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “The innovation from our labs is the foundation for our industry-leading XLamp LED family and an invention that continues our leadership of the LED lighting revolution.”

This R&D result features advanced aspects of the same technology used in Cree XLamp white LEDs. Cree believes higher-performance LEDs can enable new LED-based applications and drive down the solution cost of current LED-based designs.

While this level of performance is not yet available in Cree’s production LEDs, Cree continues to lead the industry with the broadest family of high-performance LEDs.

CDIL announces LED product range for Indian market

NEW DELHI, INDIA: Continental Device India Ltd (CDIL), pioneers of manufacturing silicon semiconductor devices in India since 1964, launched its LED Product Division to extend the Indian lighting market.

CDIL LED Products demonstrate its commitment to promote advancement in next-generation lighting, and to lead the way in establishing LEDs as energy-efficient, cost-saving lighting that address the needs of energy management solutions.

"Many countries have stopped usage of incandescent lamps due to low power factor. Very soon there may be a regulation on CFL usage due to disposal hazards. With shortage of power availability in India, there should be State initiatives to drive the Street lights and all other commercial lighting into LED Lighting - even if it involves subsidizing the manufacturers for initial few years. This subsidy would still be less than the money required to generate additional power." explains Pankaj Gulati, executive VP and COO, CDIL.

CDIL product line in India features an extensive LED Tube Light line, a high-efficiency LED Street Light line along with LED Bulbs and Solar Home Lighting Products. The LED Tube Light line includes the usage of SMD as well as DIP technology, which uses G13 sockets and fits into the existing FTL fitting. The usage of choke and starter shall be eliminated completely.

The LED tube light consumes almost 50 percent less energy as compared to normal fluorescent tube light with 3-5 times more life. The large industrial companies, where tube lights are continuously running are moving towards LED tube lights resulting in a direct energy cost reduction. The hesitancy to change immediately is on account of higher cost of LED tube lights, which is expected to come down as the volume increases.

Design and Development capabilities nurtured at CDIL have resulted in truly world class products. Development of various LED Display board has also led to increase in the sales of CDIL LED Division. "LED Lighting has its share of challenges as it is more expensive compared to standard lamps and CFLs. How deep it penetrates is largely dependent on how affordable we make the LED product. This involves reorientation of standard processes and design to enable integrate optics, driver electronics and thermal dissipation all to be integrated into an affordable LED lighting products," adds Gulati.

CDIL LED lighting products offer a number of advantages over traditional incandescent or fluorescent lighting, including a longer product life. CDIL LED light operates for no less than 50,000 hours, which reduces power consumption and CO2 emissions. Additionally, CDIL products contain no toxic mercury substances such as those found in compact fluorescent bulbs.

CDIL products offer the following features:

* high-energy efficiencies,
* long life and high reliability,
* high-color rendering,
* mercury free,
* low UV/IR radiation, and
* conforms to CE standards.

CDIL further plans to offer various solar based street lights and designer concept lights in the coming quarter to the Indian lighting Market.

"The segment of industrial lights is also new to the LED industry with its contribution being 1/10th of the LED market. However, the growth witnessed by this segment is about 20 per cent," informs Ravinder Gulati, deputy GM, LED division, Continental Device India Ltd (CDIL).
