GIGABYTE’s new Glass Fabric PCB technology helps your PC win war against humidity

MUMBAI, INDIA: Many parts of India experience moisture in the air as ‘humidity’ almost through the year. There is nothing more harmful to the longevity of your PC than moisture. To give the ultimate protection to your PC from humidity, GIGABYTE Technology (India) Pvt Ltd, a leading manufacturer of motherboards, has recently launched in India, a motherboard series with its new, innovative Glass Fabric PCB technology that repels moisture caused by humid and damp conditions.

The Glass Fabric PCB technology uses a new PCB material which reduces the amount of space between the fiber weave, making it much more difficult for moisture to penetrate, compared to traditional motherboard PCBs. This ensures a much better protection from short circuits and system malfunctions, caused by humidity. This unique kind of PCB process actually helps protect the motherboard from moisture at the PCB level, with improvements to how the actual PCB structure is manufactured.

The problem with traditional PCB manufacturing is a process known as Conductive Anodic Filament (CAF). This basically describes a situation where the copper conductive filament forms a laminate dielectric between the adjacent conductors. This can be a major source of electrical failure and is believed to be caused primarily by humidity or moisture, which results in a hydrolytic reaction with the copper within the motherboard with the passage of time. Moisture is believed to enter the PCB via the holes in the board where IC components are attached.

GIGABYTE’s Glass Fabric PCB technology that allows for a finer glass fiber weave, makes it much more difficult for moisture to penetrate, even when holes are made to mount components.

USHIO Group's EUV light source achieves output of 30W at intermediate focus

2011 International Symposia on Extreme Ultraviolet Lithography and Lithography Extensions, TOKYO, JAPAN: USHIO Inc. announced that its wholly owned subsidiary, XTREME technologies GmbH, has achieved the output of 30W at an intermediate focus under a duty cycle of 100 percent, which is indispensable for the high-volume manufacturing in EUV lithography.

The company reported this achievement during a presentation in an international conference for EUV lithography — the 2011 International Symposia on Extreme Ultraviolet Lithography and Lithography Extensions — held in Miami, Florida (USA), on October 17–21, 2011.

An EUV light source with an extremely short wavelength of 13.5 nm is said to be the last light source for the semiconductor lithography process; it is necessary for the manufacturing of semiconductor devices on and after the 22-nm generation. USHIO has been developing EUV light sources of the Laser-assisted Discharge Plasma (LDP) method, which generates an EUV from a discharged plasma, since the 1990s. USHIO acquired full ownership of XTREME technologies in 2008, and purchased the assets of Phillips Extreme UV in 2010, to aggressively promote the research and development of EUV light sources.

XTREME technologies had already achieved an output of 15 W at an intermediate focus point under a duty cycle of 100% in February 2011. The stable output of 30W was achieved by solving the problems caused by increasing the output, such as debris and thermal processing. The company already has the solutions for these problems to enable a further increase in the output. Therefore, we will continue to develop the light source with higher output.

"We have already confirmed an output equivalent to 100 W at an intermediate focus with a prototype light source. We have reached the stage of achieving an output of 30 W at an intermediate focus with continuous emission," said Masaki Yoshioka, executive VP and CTO of XTREME technologies. "We have steadily progressed in the development of the EUV source to achieve further, higher outputs of 100W and 250W while solving critical engineering problems one by one."

USHIO is accelerating development of the LDP EUV source for high-volume production in EUV lithography through XTREME technologies.

The North American flexible circuit book-to-bill ratio in September 2011 fell to 0.97.

For rigid PCBs and flexible circuits combined, industry shipments in September 2011 decreased 12.0 percent from September 2010, as orders booked decreased 18.4 percent from September 2010. Year to date, combined industry shipments were down 0.2 percent and bookings were down 9.6 percent. Compared to the previous month, combined industry shipments for September 2011 increased 4.9 percent and bookings decreased 7.3 percent. The combined (rigid and flex) industry book-to-bill ratio in September 2011 declined to 0.99.

“Sales and orders were both under last year’s levels in September,” said IPC president and CEO Denny McGuirk. “Bookings have been especially sluggish and that has caused a drop in the book-to-bill ratio … although it is still very near parity, which suggests that flat sales is the likely near-term scenario.”

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.

Book-to-bill ratios and growth rates for rigid PCBs and flexible circuits combined are heavily affected by the rigid PCB segment. Rigid PCBs represent an estimated 89 percent of the current PCB industry in North America, according to IPC’s World PCB Production Report.

Role of domestic production
IPC’s monthly survey of the North American PCB industry tracks bookings and shipments from U.S. and Canadian facilities, which provide indicators of regional demand. These numbers do not measure U.S. and Canadian PCB production. To track regional production trends, IPC asks survey participants for the percent of their reported shipments that were produced domestically (i.e., in the USA or Canada).

In September 2011, 85 percent of total PCB shipments reported were domestically produced. Domestic production accounted for 85 percent of rigid PCB and 83 percent of flexible circuit shipments in September by IPC’s survey participants. These numbers are significantly affected by the mix of companies in IPC’s survey sample, which change slightly in January, but are kept constant through the remainder of the year.

Bare circuits vs. assembly
Flexible circuit sales typically include value-added services such as assembly, in addition to the bare flexible circuits. In September, the flexible circuit manufacturers in IPC’s survey sample indicated that bare circuits accounted for about 53 percent of their shipment value reported for the month.

Assembly and other services make up a large and growing segment of flexible circuit producers’ businesses. This figure is also sensitive to changes in the survey sample, which may occur at the beginning of each calendar year.

Cree redefines high-voltage LEDs

DURHAM, USA: Cree Inc. announced the commercial availability of high-voltage XLamp XT-E and XM-L LEDs. These new LEDs can enable the use of more efficient, smaller drivers to lower cost for compact lighting applications such as candelabras and retrofit lamps.

“The XLamp XM-L High-Voltage LED eliminates the trade-off between size and efficacy, allowing us to take advantage of the efficacy of high-voltage drivers,” said Ken Chakravarti, CTO, Ledzworld. “This translates to more efficient, better and more cost-effective small LED lamps and luminaires such as the B10 replacement lamp for our customers.”

Small-form-factor lighting, like candelabras, historically presented a host of challenges for LED technology. Prior LEDs were unable to deliver the required system-level performance in the form factor consumers demand.

“Maximizing the LED voltage, as Cree has done in the new high-voltage XM-L and XT-E LEDs, is a very effective way to minimize current through the LED driver output rectifier,” said Peter Vaughan, director of applications engineering, Power Integrations Inc. “This can reduce losses and heat dissipation in the driver and increase the overall system luminous efficacy by several percentage points.”

“Never before have lighting OEMs been able to leverage the benefits of high-voltage LEDs with this level of performance,” said Paul Thieken, Cree director of marketing, LED components. “We continue to develop the right LEDs for the right applications—to accelerate the adoption of energy-efficient LED lighting.”

The XLamp XM-L LED delivers up to 600 lm in Cool White (6000K) and up to 462 lm in Warm White (3000K) at 6W, 85°C. The XLamp XT-E LED delivers up to 300 lm in Cool White (6000K) and up to 228 lm in Warm White (3000K) at 6W, 85°C. Both LEDs have a typical voltage of 46V at binning conditions.

XLamp XT-E and XM-L LEDs are available now in production quantities with standard lead times.

LEDforum Taipei: Brand new chapter for LED industry!

TAIWAN: LED-related technologies have been developing rapidly over the recent years, and the industrial chain has been focused on innovative applications. The financial crisis in 2011 not only triggered rapid changes in the global LED market but it also added factors of uncertainty for the LED industry.

From November 1 to November 2, 2011, several industry heavyweights, including the inventor of GaN LED Dr. Shuji Nakamura, the inventor of yellow LED George Craford and LEDinside’s analysts will be participate in this analysis of the global LED industry at the LEDforum 2011 Taipei. This is an annual LED seminar organized by LEDinside, a research division of TrendForce.

Dr. Shuji Nakamura, the inventor of GaN LED and a professor of University of California, Santa Barbara, and George Craford, a SSL fellow of Philips Lumileds, will address the ground-breaking developments of the LED industry. Nakamura states that since 2001, the invention of nonpolar and semipolar GaNs gave LEDs and LDs higher efficiency. The short efficacy droop of the (20-2-1) LED will help the development of blue and green LDs.

Compared with other semipolar LED’s uneven efficiencies, the new LED still requires further research. On the other hand, Craford points out that LED lighting application sector is on the verge of entering the next generation. He is optimistic about the future of LED lighting and the prospects propelled by the LED chip efficacy and quality enhancement.

Moreover, experts of MOCVD equipment major makers Aixtron, Veeco will analyze the manufacture of LED. The continuous improvement of MOCVD equipment will decrease the manufacturing cost and carbon footprint and increase the capacity of upstream LED chip manufacturers

From the market perspective, LEDinside analyst team predicts that LED’s penetration rate in the HBLED market will increase from 24 percent to 52 percent in the next five years; by 2012, the LED backlight market is expected to face weak demand and underperformance of LED penetration rate.

Due to the improved economy growth of 2011, the value of the global lighting market will increase by 5.6 percent to $83.9 billion. Most notably, the European market plays an integral role in the global LED lighting market, accounting for 27-28 percent of the market value, which will most likely surge to 47 percent in the next five years.

Looking beyond Europe, the Chinese LED market is another major focus. LEDinside’s analysts believe that China’s subsidy policies spur the development of the LED industry: China taking up 15.4 percent of the value of the global lighting market is a testament to it. However, China’s present currency policy will affect local governments’ policies and loans of enterprises, which will cause LED chip makers to terminate their expansion plans.

Chinese and South Korean manufacturers drastically cut prices; competition in LED market intensifies

TAIWAN: According to the latest price survey conducted by LEDinside, a research division of TrendForce, the price downtrend persisted in the LED market in 3Q11. The price of LED (5630) for TV backlight dropped by 8-15 percent. Since TV backlight products will start adopting 7030 spec in 2012, South Korea manufacturers have been aggressively digesting the inventory of older specification, which result in a huge price gap in the market.

The price of high-power LED plunged by approximately 8-10 percent, which is less drastic compared to drop in 2Q11. The minor price plunge reflects the fact that the lighting market’s demand is rather stable, but huge orders are still rare in the market. Looking at 4Q11, in addition to transition from the old to the new specification, the LED makers will continue to face inventory pressure. Hence, the prices of LED (5630) for TV backlight and high power LED are expected to continue to fall.Source: LEDinside, Taiwan.

Transition to new module triggered apparent decline in TV backlight price
Due to the underperformance of LCD TV sales in 3Q11, the price of LED (5630) for TV backlight took the most considerable dip of 10-15 percent. Most notably, LCD TV manufacturers plan to adopt new the 7030 spec in 2012, resulting in an uncertain price outlook in the market. South Korean manufacturers’ aggressive inventory digestion caused a huge price gap in the market. LEDinside predicts that the price will continue to drop in 4Q11.

South Korean and Chinese makers to spur price competition in portable device market
Due to its maturity, the LED price for the notebooks, monitors and mobile devices only experienced a slight drop of 5-10 percent. As for mobile phone’s backlight module, the price drop averaged 8-10 percent.

LEDs for notebooks and mobile devices are relatively cheap, and they are the key products for Taiwanese LED manufacturers. However, as more and more Chinese LED manufacturers have made their way into the mobile backlight market while South Korean makers’ increasing their focus on mobile backlight module, the price competition is expected to intensify.

LED for lighting products experienced relatively small price downtrend; price competition remains fierce
The decreased growth momentum of the LED lighting market in 3Q11 was caused by the global economy climate. The market demand is mainly underpinned by the indoor lighting sector.

In order to obtain cost competitiveness, the majority of LED indoor lighting products adopt 5630 and 3014 LED packages, which compromises the demand for high-power LED. In addition, the manufacturers continue to cut prices in order to stimulate demand. However, due to the sharp appreciation of US dollar and Renminbi, Taiwanese maufacturers’ LED prices merely dropped 5-10 percent after they were converted into NT dollar, which alleviates their price pressure.

On the other hand, the price competition between global major companies remained fierce. In particular, these major global firms each offer more room for price negotiation for important clients; Japanese, South Korean, European and American manufacturers have all cut prices. As for 4Q11, LED inventory pressure will most likely persist. The uncertain economic conditions affect manufacturers’ inclination to purchase materials in advance, which will in turn cause price downtrend in 4Q11.

Digi-Key now stocks TE Connectivity’s reflowable thermal protection (RTP) device

THIEF RIVER FALLS, USA: Digi-Key Corp. announced the addition of TE Connectivity’s Reflowable Thermal Protection (RTP) solutions to its vast product line.

TE’s RTP device is the industry’s first SMD thermal protector. The RTP device helps prevent thermal damage caused by failed power components and can withstand the demanding environmental, life, and reliability requirements of automotive and industrial applications, including shock, vibration, temperature cycling, and humidity exposures.

In the field, an RTP device opens if its internal junction exceeds the device’s specified open temperature. Temperature increases can have multiple sources, one of which is component failure (i.e. when using power components such as a power FET, capacitor, resistor, triac, etc.). The RTP device’s open temperature is selected so that the device does not open within normal component operating windows, but it does open in a thermal runaway event and before the melt temperature of typical lead free solders.

The RTP device helps provide protection against damage caused by thermal runaway for power FETs and other components if failure occurs in applications such as automotive HVAC, ABS, power steering, DC/DC converters, PTC heaters, or IT servers, telecom power, or converters.

Rubicon begins on-site processing of aluminum oxide used to ensure high quality, sapphire crystal growth

BENSENVILLE, USA: Rubicon Technology Inc., a leading provider of sapphire substrates and products to the LED, RFIC, Semiconductor, and Optical industries, announced that the company has begun the transition to on premise processing of aluminum oxide used for the production of sapphire wafers.

Using a customized in-house method, Rubicon converts raw aluminum oxide powder into a form usable in the company’s industry-leading crystal growth process, Rubicon ES2. This process enables the company to reduce its manufacturing costs while increasing control of the quality of its raw materials.

In addition to providing greater control of quality and cost, this new process developed by Rubicon’s team of crystal growth engineers forms the powder into different shapes which can optimize the space in the crucibles in its crystal growth furnaces, thereby resulting in larger crystals.

“As the LED industry transitions to larger diameter substrates, ensuring a steady supply of raw material becomes increasingly important,” said Raja Parvez, Rubicon president and CEO. “Large diameter wafers are as much as three times thicker than two- to four-inch wafers and require more aluminum oxide. As the world’s leader in large diameter sapphire, it is important that our new on-site processing capability brings us a reliable supply of raw material that we can process into large diameter sapphire wafers for LED manufacturers.”

Advances in raw material handling combined with recent company-wide installation of enhancements to its proprietary crystal growth furnaces, Rubicon Furnace Version ES2-XLG3.0, delivers cost efficiencies for the production of large diameter sapphire. Rubicon’s next generation ES2-XLG3.0 furnaces provide automation for vacuum monitoring and crystal growth rates for greater yield consistency. The furnaces require less operator intervention at five employees per 100 furnaces at any given time. ES2-XLG3.0 furnaces operate in Rubicon’s United States high-efficiency crystal growth facilities in Batavia and Bensenville, Illinois.

The transition to larger diameter wafers in LED production has started. Several key LED chip manufacturers have announced plans to migrate to and/or test large diameter wafers in 2011/2012. Rubicon’s robust process platforms for large diameter sapphire wafers and the company’s ability to scale to commercial volumes, creates superior performance factors for the LED industry.

Fairchild's smart LED lamp driver IC solves small-space dimming challenges for designers

SAN JOSE, USA: As LED lighting continues to grow in popularity, especially in residential lighting applications, designers are looking for efficient dimming solutions – when compared to TRIAC methods – that also fit within existing sockets. Additionally, these solutions need to work reliably in a small space while providing high efficiency.

To help designers meet this challenge, Fairchild Semiconductor, a leading global supplier of high performance power and mobile products, developed the FL7701 Smart Non-isolated Buck LED Driver with power factor correction (PFC). The device uses a digital technique that allows it to automatically detect the AC input voltage condition, allowing it to create a special internal reference signal that results in high power factor correction.

The FL7701 will also work from a DC input voltage condition, automatically sensing AC versus DC input voltage conditions. The traditional technique of using a transformer in an MR application incurs additional losses with the transformer conversion; this traditional inefficient method can now be replaced using the FL7701 connected directly to a DC or AC off-line input.

The FL7701 combines high functional density in a small form factor that provides designers up to 20 percent lower bill of material (BOM) costs and up to 60 percent board space savings. This combination creates a solution suitable for the space-constrained PCB sizes found in LED lighting applications and supports analog dimming.

The high degree of integration designed into the FL7701 provides the high reliability required to increase the luminary lifespan to more than five years, compared to the three years achievable by current solutions. Reliability is also improved since no electrolytic capacitors for the input, output, or the FL7701 VDD supply are required.

Digital power factor (PF) realization (>0.9) and lower total harmonic distortion (THD), along with the 90 percent electrical efficiency results in increased energy savings for the end system. Combined, these features allow the FL7701 to provide energy savings that meet the most stringent worldwide regulations, such as Energy Star.

Fairchild’s IC design technology results in high power efficiency (>90 percent) and provides high light quality required for residential applications. Available in an SOP-8 package, the FL7701 is ideal for interior decorating/ornamental lights; LED light bulbs or down lights in PAR, Reflector, MR or classic styles E26/E27 or Bi-Pin base, as well as LED lamps for low power lighting fixtures.

Fairchild offers a total solution portfolio for low- (<20W), mid- (20W to 50W) and high- (>50W) LED driver applications. Our highly integrated PWM and PFC controller solutions reduce component BOM counts to enable smaller lamp sizes and eliminate design complexities, while improving overall lighting efficiency. Fairchild’s extensive product portfolio ranges from discrete devices to integrated solutions that contain PFC controllers, high voltage gate drivers and MOSFETs.

With commitment to energy savings and meeting the most stringent regulations, Fairchild has developed innovative products that maximize performance while reducing board space, design complexity and system costs. In addition, Fairchild’s Global Power ResourceSM Center comprised of online tools, FAEs and regional centers staffed by power engineers, is the industry standard for customer design support.

2011-2015 Chinese LED lighting market report: Street lamp market analysis

TAIWAN: In the past, traditional street lamps were primarily HID lamps and mercury lamps. However, due to disadvantages such as lumen decay, high power consumption and short lifespan, traditional light sources are no longer in line with the global energy-saving trend. LED quickly made its way into street lighting due to several factors, including carbon emission reduction policies enforced worldwide and improved luminous efficacy LED light sources (a total luminous efficacy of over 100–130 Lm/W and an application luminous efficacy of over 50 Lm/W), as commercial opportunities presented themselves.

The “10,000 Lamps in 10 Cities” program has been changed to “2 Million Lamps in 50 Cities” in order to further expand the application of LED street lamps. Although China, with the largest domestic demand worldwide, is considered the global LED industry’s priority market for LED street lamp, there is still a long way to go before LED street lamps reach wide adoption. Given that LED street lamps are large-size luminaires, long, practical tests and well-established standards should precede the launch of a large-scale promotion.

Moreover, it is almost time to inspect the results of the LED street lamps instituted from 2009 to 2011 for demonstration. If the results and benefits meet the expectations, it will strengthen Chinese government’s faith in popularizing the LED street lamps in first-tier cities, which will be a crucial breakthrough for LED applications.

LEDinside, a research division of TrendForce, believes that LED street lamps will most likely see the fastest growth rate in 2012. In 2009, the Chinese government planned and implemented LED street lamp installation programs in 21 cities, aiming to set up one million LED street lamps. However, surveys showed that the actual number of LED street lamps installed in 2009 was less than 20 percent of the planned quantity, falling vastly short of targets.

As for the “2 Million Lamps in 50 Cities” program implemented from 2010 to 2012, a rough estimate suggests that the number of installed LED street lamps reaches about 150,000~200,000 as of July, 2011.Source: LEDinside, Taiwan.

Markets for OLED encapsulation - 2011

GLEN ALLEN, USA: NanoMarkets announced the release of its latest market report on OLED materials titled, "Markets for OLED Encapsulation – 2011."

In the report NanoMarkets ties the opportunities for OLED encapsulation suppliers to the emergence of OLED lighting. And while NanoMarkets predicts a modest but still significant market potential for OLED encapsulation of approximately $170 million ($US) in the year 2016, this time period will also coincide with the emergence of OLED lighting as a volume market leading to significant upside for encapsulation suppliers.

In this new report, NanoMarkets analyzes and quantifies the opportunities for encapsulation suppliers in the fast-growing OLED market. We examine the product development and marketing strategies of the major players in the OLED encapsulation materials sector, from large multinationals like 3M, DuPont and Corning to specialty firms like Tera Barrier Films, and we also attempt to indicate which are the "companies to watch" and which will be the likely winners and losers in the encapsulation materials space. Finally, this report contains detailed, eight-year forecasts of the OLED encapsulation market broken out by product type and by OLED application.

OLED firms are beginning to recognize that high quality encapsulation is an area of strategic importance. NanoMarkets believes that we are now seeing some real opportunities for the firms that have been working on the encapsulation issue, many of whom have poured resources into this area for several years. In fact, encapsulation is the key enabling technology for the larger-format/longer lifetime OLEDs that will be entering the market in the near- to mid-term, and thus can unlock entire market segments.

Small, rigid OLED displays are now widely commercially available and expected to continue to expand, principally in smartphone and other mobile computing displays and the OLED TV market is finally poised to take off within the next few years, as display manufacturers launch newer, bigger models with better value propositions for customers.

The emergence of the OLED lighting industry will be the defining opportunity for OLED materials suppliers turning a niche market into a significant opportunity after 2015.
Glass encapsulation technologies heavily dominate the market today, and glass will continue to dominate in the near- to mid-term.

However, the consensus is that glass will not be sufficient for the types of OLEDs expected to emerge over the next decade. OLED panels are getting larger, and the emerging lighting and TV markets expect OLED panels to last much longer than the mobile phone and mp3 sub-displays of the past. Furthermore, the cost pressures are getting more serious. The days in which manufacturers were willing to pay high premiums for good encapsulation strategies are long gone, and low-cost options for encapsulation are now demanded.

Linear LED driver from Diodes Inc. simplifies low-power LED control

PLANO, USA: Diodes Inc. announced the AL5802 linear LED driver. Integrating a high gain NPN transistor with a 30V rated pre-biased NPN output transistor, the AL5802 provides a simple, cost-effective and low EMI solution for controlling current in up to 9 low-power series-connected LEDs. With an open-collector output capable of operating between 0.8V to 30V, the SOT26 packaged driver supports 12V and 24V power supplies and delivers LED currents between 20mA to 100mA for LED signs, lamps and automotive interior display applications.

The LED current is set by an external low-value resistor, the one additional component required by the driver. By generating a reference voltage of 0.65V across the resistor, the internal high-gain transistor helps minimize power losses and ensures supply voltage headroom. The negative temperature coefficient of the reference voltage means that LED current is automatically reduced at high temperatures, thereby helping to protect LEDs and improve circuit reliability.

PWM dimming of the LED string is also simple to achieve by either driving the device bias pin with a low-impedance voltage source or driving its enable pin with an external open-collector NPN transistor or open-drain N-Channel MOSFET. The AL5802’s wide ambient temperature operating range of -40ºC to +125ºC enables it to be circuit mounted very close to the LEDs in space-limited lighting applications.

Inventors of GaN LED and yellow LED to speak at LEDforum Taipei 2011

TAIWAN: LEDforum 2011, the largest LED seminar in Taiwan, is scheduled to be held on November 1-2, 2011 at the NTUH International Convention Center in Taipei. Organized and held by LEDinside, a research division of TrendForce, LEDinside analysts will present in-depth analyses on both European and Chinese markets and provide perspectives on the market trends and outlook during this two day event.

Moreover, the inventor of GaN LED Dr. Shuji Nakamura and the inventor of yellow LED, George Craford will both be speaking at the LEDforum 2011, addressing the cutting edge trends of the LED industry and LED innovations and application in next generation lighting, respectively.

Most notably, Dr. Shuji Nakamura, honored with Nobel Prize nomination and Millennium Prize, came to Taipei, Taiwan for a sold-out speech in 2007. Dr. Nakamura earned the title of “the inventor of GaN LED” due to his success in inventing GaN LED. In the early days, the difficulty of manufacturing GaN (blue) LED was a real stumbling block to creating colorful RGB basic color palette for LEDs.

However, after Dr. Nakamura solved the manufacturing issue of GaN LED, it spurred the invention of white LED, which contributes to the wide adoption of LED applications today. The perspectives of LED’s two iconic figures will illuminate the path to the next generation LED lighting.

LEDforum 2011 is a two-day seminar organized by LEDinside, which will be held at the NTUH International Convention Center on November 1-2, 2011. On the first day of LEDforum, the sessions will dissect the trends of LED upstream material, equipment and chip markets; the sessions on the second day will tackle the issues of LED lighting applications, driver IC and package and shed light on the big picture of LED industry, helping the participants get a firm grasp of the market dynamics.
