AU Optronics' First Mobile LTPS Panel with PenTile RGBW Technology Dramatically Improves Power Efficiency in High-Resolution Displays; 2.8-inch VGA Panel with Clairvoyante Technology is Twice as Bright; Uses 50 Percent Less Power.YOKOHAMA, Japan -- AU Optronics (TAIEX TAIEX Technical Assistance Information Exchange Office (EU) TAIEX Technical Assistance Information Service :2409) (NYSE NYSE See: New York Stock Exchange :AUO AUO Au Optronics Corporation AUO Administratively Uncontrollable Overtime AUO Active User Object AUO Aggravated Unlicensed Operation (of a Motor Vehicle) AUO Area Utilization Officer AUO alt.usenet. ) and Clairvoyante have teamed up to develop power-efficient mobile liquid crystal displays with the introduction of the first Low Temperature Polysilicon (LTPS See LTPS TFT LCD. ) panel integrated with PenTile RGBW RGBW Royal Gloucestershire, Berkshire and Wiltshire (regiment) (TM) technology from Clairvoyante. AUO's 2.8-inch high-resolution VGA (Video Graphics Array) The display standard for the PC. All PC display adapters support VGA, and Windows machines boot up in "VGA mode" before switching to higher resolutions. panel improves light throughput by more than 100 percent and enables a 50 percent power reduction over LTPS-only. Panels enhanced with PenTile RGBW technology can offer either twice the brightness or some combination of improved power and brightness. AUO, which manufactures a wide range of display products for the mobile market, is the first LCD provider to integrate LTPS with PenTile RGBW technology for handheld applications. Both companies will demonstrate the new VGA panel this week at FPD (1) (Flat Panel Display) See LCD, plasma display, EL display, FED and flat panel display. (2) (Field Programmable Device) An umbrella term for all chips that can be programmed by the customer including SPLDs, CPLDs and FPGAs. See PLD. International in Yokohama, Japan. The LTPS with PenTile RGBW panel will be displayed next to a similar LTPS module without PenTile RGBW technology. LTPS technology has already proven to be an excellent manufacturing process for high-resolution, high-brightness panels. Its high level of integration and use of small transistors enables an exceptional aperture ratio and brightness for high-resolution displays. However, in data-centric applications it uses a large number of backlights that need to be on for extended periods, increasing power consumption and cost and inhibiting its full potential in power-hungry, feature-rich handsets. Clairvoyante's patent-pending PenTile RGBW technology, which is based on extensive research on the human visual system, offers substantial power savings without impacting brightness or other performance. Coupling PenTile RGBW and LTPS technology enables the industry's most transmissive high-resolution displays. Substantial Power Savings Expectations for power consumption are straining the capabilities of existing technology, while the convergence of feature-rich handsets requires higher performance displays along with even more power-depleting processing. PenTile RGBW technology offers dramatic power savings over RGB (Red Green Blue) The computer's native color space, which is the color system for capturing and displaying images. RGB was derived from our own perception of color because human eyes are sensitive to red, green and blue (see trichromaticity). Stripe and positions AUO's VGA panel as the best low-power technology capable of meeting a high standard of resolution. Clairvoyante's technology adds a white subpixel and utilizes fewer required pixels, reducing the number of drivers by one-third over RGB Stripe without compromising visual resolution. This improvement also provides for more space to integrate components, such as the LCD power supply, onto the glass. PenTile RGBW technology also allows the number of backlight back·light n.

These factors enable a 50 percent power reduction over LTPS-only. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2.

Clairvoyante president and chief executive officer Joel Pollack, "In order to meet the increasing power demands set by the rising number of data-centric mobile applications, makers of baseband processors and graphics chips are applying considerable time and financial resources to save tens of microwatts. Using PenTile RGBW technology in a VGA display can save up to 250 milliwatts of power, or 100 milliwatts in a qVGA display." Further Increase to Brightness LTPS with PenTile RGBW technology achieves high brightness without taxing the power supply, which is critical in mobile environments. LTPS uses narrower metal lines in the fabrication fabrication (fab´rikā´sh  n),n the construction or making of a restoration. , resulting in smaller transistors, improving brightness by increasing aperture ratio. PenTile RGBW technology adds a white subpixel to the traditional arrangement of red, green, and blue subpixels, increasing transmissivity and brightness. Nearly twice the white brightness can be achieved with no power increase, due to the larger aperture ratio of the bigger subpixels, and utilization of white (clear color filter Color filter An optical element that partially absorbs incident radiation, often called an absorption filter. The absorption is selective with respect to wavelength, or color, limiting the colors that are transmitted by limiting those that are absorbed. ) subpixels.

"Being able to apply the ultra-high transmittance of PenTile RGBW technology to both our LTPS and amorphous silicon Silicon that does not have a crystalline structure and which is not conductive. Contrast with polysilicon. processes will help us better manage the cost of materials while allowing us to produce a range of products that meet increasingly high consumer expectations." Mobile Applications LTPS + PenTile RGBW technology is particularly ideal for mobile products such as cellular phones, PDAs and other mobile devices demanding high-resolution displays, where video and text must be crisp and bright and battery life is critical. AU Optronics already offers a wide selection of panel sizes and technology for mobile phone displays; this product further extends their leadership in the mobile products space. Estimated Power Reduction for 2.8-inch VGA This week at FPD International, both companies will exhibit the LTPS with PenTile RGBW panel alongside an identically-specified LTPS panel built without PenTile RGBW technology. When compared to an RGB stripe design of equivalent size and resolution, a 2.8-inch VGA LTPS panel with PenTile RGBW technology uses 50 percent less power without affecting brightness. The table below compares these panels:

Source drivers are lowered from 1,440 to 960, lowering clock frequency and, therefore, power consumption. Even more significantly, by reducing the number of backlight LEDs from eight to five, power is nearly halved, brightness is maintained, and cost is also reduced. Availability Prototypes will be exhibited alongside an LTPS-only version through Friday at FPD International at Pacifico Yokohama Pacifico Yokohama (パシフィコ横浜) is a convention center in Japan located in the western region of Minato Mirai Nishi-ku Yokohama, Kanagawa Prefecture. , in Booths 781 and 680. AUO expects mass production of the 2.8-inch VGA panel by the second quarter of next year; the panels are targeted at the 3G mobile phone market.
