This panel features 200 pixels per inch (ppi), according to Seiko Epson.

Most of the high-definition LCD panels of around 200ppi are low-temperature polycrystalline silicon TFT types. However, Seiko Epson built the new panel by adopting a low power-consumption and low-cost TFD method.

Such 200ppi-class, high-definition LCD panels, which can show a more extensive map more clearly, will be needed for mobile phones with GPS capabilities. Seiko Epson has met such a need by enhancing its TFD-LCD panels’ definition from 150ppi to 200ppi. According to the company, it has succeeded in realizing such enhancement through the development of a new driver LSI chip and the review of the panels’ processes.

The new panel is a semi transmission-type. Its screen diagonal size is 2 inches, the number of its pixels 240 x 320 dots, the number of its displaying colors up to 260,000 colors, and its contrast at transmission is 60:1.

Seiko Epson aims to begin volume production in the first half of 2003.
