Sanyo Epson has announced the development of a 2.2-inch amorphous silicon TFT liquid-crystal display (LCD) that is just 1.1 mm thick, making it ideal for use in mobile phones and other portable devices. As part of its HCL-S strategy (High quality, Compact design, Low power consumption, System solutions), Sanyo Epson focused on producing the thinner and lighter components demanded in the mobile devices market to develop an ultra-thin 2.2-inch amorphous TFT LCD that is just 1.1 mm thick. This ultra-thin amorphous TFT display is designed specifically for use in mobile phones, where the trend toward slimmer devices is especially pronounced.



Sanyo Epson succeeded in developing this 1.1-mm-thick amorphous TFT LCD by using ultra-thin components, including the backlight, polarizing plate, and glass substrate. By incorporating its proprietary design technology to boost transmissivity, Sanyo Epson was able to achieve high surface brightness of more than 350 candelas per square meter, as well as QVGA (320 x 240 pixel) high definition. These features make the ultra-thin 2.2-inch amorphous silicon LCD ideal for displaying video and receiving "One Seg," a new service in Japan enabling digital TV broadcasts to be viewed on mobile phones.

In addition, the new display is fully compliant with the European Union's RoHS (restriction of the use of certain hazardous substances in electrical and electronic equipment) Directive. Sanyo Epson intends to commercialize the new display for use in mobile phones and other new applications.

Sanyo Epson will exhibit the ultra-thin 2.2-inch amorphous silicon LCD at FPD International 2006 organized by Nikkei Business Publications, to be held from October 18 to 20 at Pacifico Yokohama.
