Sharp Develops New LCD Display Technology for Mobile Applications
Posted Oct 7, 2003 Print Version     Page 1of 1

Enhanced color reproduction now brings superior image quality to mobile devices for displaying image and video data as Sharp Corporation announced the development of a new TFT liquid crystal display technology.  

The new LCD modules combine technology characteristics of the Sharp AQUOS Liquid Crystal TV, referred to as the ASV LCD, with Sharp's proprietary small format display technology, referred to as the Advanced-TFT. With this, Sharp has attained a new mobile display that is ideally suited for the following mobile devices:  camera phones, PDAs, and personal media players, all of which display streaming video content or color images. The displays achieve excellent visibility in a variety of lighting situations.  It also offers a wide viewing angle, high contrast ratio, and superior color reproduction.

The displays are slated for sampling in December of 2003, with volume production to begin next spring.

Sharp also developed mobile ASV LCD technology which combines its Advanced Super View LCD and Advanced-TFT(2) LCD technologies. Advanced Super View technology is used in its AQUOS LCD TVs, while its Advanced-TFT technology is in the company's transflective LCD displays integrated into devices such as mobile phones and PDAs. The result of this convergence is a new, LCD technology that allows modules to exhibit video and photographic-quality still images.

The new displays are produced using Sharp's Amorphous silicon and CG-Silicon manufacturing processes. They range in size from 1.5-inch to 6.5-inches, and feature color purity within a viewing cone of 160 degrees vertically and horizontally. With a symmetric viewing cone, the displays can be used in portrait mode for graphics and landscape mode for video, enabling viewing even when held in the hand or laid flat on the table. This technology is compatible with a range of products that will be offered in VGA and QVGA resolutions. The displays feature a 25ms response rate, and 300:1 contrast ratio.
