Abstract

A 7-in-diagonal active-matrix color LCD with 520 × 520 pixels addressed by a-Si thin-film transistors has been developed. The display has a wide viewing angle and a contrast ratio of 4 under intense 100 000-lx illumination. The construction and performance of the panel are described in this paper.
