Overview
abstract
A novel reduced mask process is used to fabricate high-resolution high-aperture-ratio 10.5-in. SXCA (1280 1024) displays. The process uses copper gate-metallurgy with redundancy, without the need for extra processing steps. The resulting displays have 150-dpi color resolution, an aperture ratio of over 35%, and excellent image quality, making them the first high-resolution displays that are suitable for notebook applications.
