Driver deal to accelerate display
expansion
Tomato LSI is to produce the world's first commercially available three-chip PenTile RGBW driver for amorphous silicon TFT widescreen VGA display panels up to 5in diagonal.
Clairvoyante is expanding its licensing agreement with Korean fabless chip manufacturer Tomato LSI to include production of widescreen VGA driver integrated circuits integrated with PenTile RGBW technology, simplifying implementation of PenTile RGBW technology into widescreen mobile panels in order to increase brightness and help manage power consumption The agreement will enable liquid crystal display manufacturers to produce high-brightness, low-power display modules for the next-generation of mobile applications that are increasingly demanding high-brightness, widescreen format, and extended battery life

Display technology enables widescreen expansion
Chunghwa Picture Tubes is using PenTile RGBW technology from Clairvoyante to build widescreen high-resolution display panels for next-generation mobile devices.
The new wide-format driver IC adds to the PenTile RGBW drivers already being produced in standard-format qVGA and VGA resolutions, expanding driver solutions for manufacturers needing to increase brightness and manage power consumption of mobile display panels in a variety of resolutions.
PenTile RGBW technology can double screen brightness or reduce power consumption by 50%, making it ideal for supporting third-generation (3G) data-centric devices, which require higher-resolution, higher-brightness displays that use substantially more power than current products.

TLSI is already producing PenTile RGBW VGA drivers targeted toward high-resolution displays and can now apply their capabilities to support 3G mobile display opportunities where a widescreen version is needed for improved mobile video players, ultraportable PCs, global positioning satellite devices, and next-generation cellphones.
The driver will support 800 x 480 format and 8bit colour.
Samples are available now, with commercial production expected by Q3 2007.
According to display market analyst DisplaySearch, liquid crystal displays in all sizes and markets are moving toward a wide aspect ratio standard; small screens are no exception.
The wide format is better suited for video because it comes closer to simulating the realism of a widescreen theatre.
In certain applications such as web browsing and mapping, widescreen formats limit the amount of horizontal scrolling, or even eliminate scrolling altogether, greatly enriching the user experience.
Adoption rates of next-generation mobile content and applications are constrained by brightness and resolution levels of portable displays, as well as their battery life.
In addition to having a growing need for high-resolution screens, data-centric applications like video, games, and web browsers require displays with a minimum of 400cd/m2 of brightness - twice that of legacy mobile screens - plus, there is more "always-on" content, such as video, text messaging, and maps.
This need to increase brightness, resolution, and the long amount of time that a display is illuminated significantly degrades battery life.
Drivers integrated with PenTile RGBW technology can help mobile displays better manage their power and brightness levels, even at high resolution.
"Tomato LSI's decision to add a solution for a wide VGA PenTile RGBW driver represents an investment being made in infrastructure to improve power management and brightness of handheld products like mobile phones, especially within the widescreen arena, which is crucial for enabling the future of multimedia", said Joel Pollack, President and Chief Executive Officer of Clairvoyante.
"This will further encourage the adoption of new generations of wide-format, full-featured mobile products with better viewability and longer-lasting battery life".
