Samsung Introduces World's First VGA-class TFT-LCD Driver IC for Mobile Phones

Seoul, Korea, October 21 - Samsung Electronics today announced that it has developed a TFT-LCD driver IC chip with VGA-class resolution capable of displaying up to 260 thousand colors for TFT-LCD panels in mobile phones.

Samsung's new driver IC generates color using an entirely new driving method called sub-pixel unit driving methodology. Contrary to existing color display methods that express color pixel by pixel, this new method creates color at the sub-pixel level, representing more than two data lines from the same pixel. By composing a new pixel with the sub-pixel on the adjacent scanning line, 480x640 VGA resolution can be attained from a 240x640 half-VGA panel, the company said. This overcomes the difficult problem of putting enough wiring connections on a less-than-2.4-inch panel to support VGA

Additionally, the problem of an insufficiently bright screen caused by increased pixel density on high-resolution panels has been solved using a four-color (RGBW) rendering algorithm, which improves the brightness of TFT-LCD panels. With this four-color rendering algorithm, which extracts the white signal from R-G-B signal input and processes four-color RGBW, the luminance of the panel is increased more than 50 percent.

Conventional technologies for extracting white from red, green, and blue have been plagued with color distortion when the white color is added by more than 15 percent. Samsung's new white-adding algorithm prevents any color distortion, even when white is fully added, the company said. At the same time, uniform color quality is maintained between input and output.

"Development of high-resolution displays is urgently needed with the advent of camera phones, video phones, TV phones, and other new products that require an entirely different level of image quality," said Dr. Jin-tae Kim, vice president of the System LSI Division at Samsung Electronics. "The four-color sub-pixel rendering technology we recently developed will play a key role in the transition to ultra-high-resolution panels for mobile products. Moreover, our development of this new chip will put us in an advantageous position in the hotly-contested market for mobile-size displays."

Samsung Electronics plans to begin using its VGA TFT-LCD driver IC on high-end mobile phone models in the second quarter of 2005. The company will then steadily expand its application to other product lines.

Market analyst iSuppli estimates that the market for mobile TFT-LCDs stands at 250 million units this year, and that the number will surge to 530 million units in 2007.

LG.Philips LCD Introduces World's Largest Single-Plate AMOLED Prototype at FPD International

Seoul, South Korea, October 19 (PRNewswire-FirstCall) - At FPD International, being held October 20-22, 2004 in Yokohama, Japan, LG.Philips LCD Co., Ltd, will unveil its prototype of the world's largest, single-plate, low temperature polysilicon (LTPS), active-matrix organic light-emitting diode (AMOLED) display.

This 20.1-inch prototype, intended for future-generation TVs, significantly improves on the response time of other display technologies, and provides excellent color saturation, along with reduced power consumption, said Bruce Berkoff, the company's executive vice president of marketing.

The company will also demonstrate a full line-up of TFT-LCDs, ranging from a 7-inch Wide QVGA for automotive entertainment and navigation to a 55-inch Wide Full HD for HDTVs and multimedia Displays.

Major Sponsors and Exhibitors for ADEAC '04 Exceed Organizers' Expectations

October 12 - ADEAC '04, a unique new conference and exhibition intended to support product designers who select displays and integrate them into their products, and to help their managers make astute decisions about display technologies and system costs, has attracted major sponsors and exhibitors, said Chuck A. Pearson (Pearson & Associates), the event's Publicity Chair, from his office in Scottsdale, Arizona today. "ADEAC has surpassed all expectations for the number and significance of our sponsors and exhibitors. The sponsors are leaders in their industries, and the exhibitors are among the critical suppliers to companies that use displays in their products," Pearson said.

The event, to be held October 25-27, 2004 at the Doral Tesoro Hotel and Golf Club in Fort Worth, Texas, has attracted major sponsors, including Texas Instruments - DLP Products (Dallas, Texas); Three-Five Systems, Inc. (Tempe, Arizona); Winstead Sechrest & Minick PC (Dallas, Texas); 3M Touch Systems (Methuen, Massachusetts); LG.Philips LCD (Seoul, Korea); McKenna, Long and Aldridge (Washington, DC); and White Electronic Designs (Phoenix, Arizona).

The exhibitors include 3M Touch Systems, Amulet Technologies, Arrow Electronics, Astro Systems, Eldim, ERG, LCD Lighting, NEC Electronics America, Texas Instruments - DLP Products; Three-Five Systems, Touch International, and Yasui Seiki Co., among many others.

In addition to the exhibition, ADEAC '04 will include display system design tutorials, keynote addresses, technical sessions focused on the selection of displays and their integration into products, an evening panel session, and a networking-friendly special event.

"The ADEAC Program Committee and Organizing Committee have done a tremendous job in creating this unique conference. I believe they are providing a great service for the application and design community," said Stephen Atwood (TFS Innovative Display Systems), the conference's Program Chair, from his office in Marlborough, Massachusetts.

Philips Halts LCOS TV Activities

Amsterdam, October 6 - In a copyrighted story, Reuters revealed today that Dutch Philips Electronics said on Wednesday it would stop development and production of rear-projection televisions using LCOS chip technology because its share of the market is too small. The decision will affect some 200 employees at Philips' semiconductors and consumer electronics business units.

``It's still a young technology which requires a lot of development, and we lack the scale advantages. We're not big enough to quickly bring these products to a more mature level,'' a spokeswoman was quoted as saying in the Reuters story.

Philips, Europe's biggest consumer electronics, will focus on LCD and CRT TVs, in which it is one of the world's largest players. Philips will halt its LCOS chip production line, Reuters said, and is considering if it can partner with other companies to re-sell rear-projection TVs under its own brand. Earlier this year, the Dutch company abandoned the video front-projector market for the same reason: that it was too small to compete effectively.

STN-LCD Resurgence Slows OLED Growth 

El Segundo, California, October 6 - Rising competitive pressure from LCDs is depressing sales and pricing for organic light-emitting diode (OLED) displays this year, says iSuppli Corp., which has prompted the market intelligence company to trim its OLED sales forecast for 2004 and beyond.

Despite the revision of its market outlook, iSuppli still sees a bright future for OLED displays, with sales expected to reach more than 289 million units by 2010, more than eight times the size of the market in 2004. 

The global OLED market will rise to 35.3 million units 2004, up 110 percent from 16.8 million units in 2003, iSuppli predicts. The company had previously predicted OLED shipments would rise to 36.2 million units in 2004. 

OLED sales revenue will rise to $429 million in 2004, up 74 percent from $246 million in 2003. iSuppli previously predicted sales would rise to $470 million in 2004. 

The major reason for the lower prices and unit sales is strong pressure from STN LCDs. A slowdown in orders for OLED mobile-phone sub-displays occurred during June and July as more mobile-phone makers chose STN-LCD sub displays to reduce their overall bill-of-materials (BOM) costs. Led by Nokia, mobile-phone makers have been striving to reduce the cost and pricing of their products. 

OLED makers responded with price cuts that will help recoup sales in the fourth quarter. Nonetheless, passive-matrix OLED makers have realized that the market is unwilling to accept much of a price premium for their products. 

Active-matrix OLED products announced for release in 2004 have been delayed until early 2005. This means volume production will commence later than anticipated, extending the timeline for achieving high market revenue. 

Mobile phones are expected to remain the largest application market for OLEDs during this decade. OLEDs are moving into mobile-phone main displays in handsets that have only one display. These displays initially are passive color panels, but active-matrix OLEDs are expected to follow this market path in the future.
