A 10.5-IN-DIAGONAL SXGA ACTIVE-MATRIX DISPLAY

A 157-dot-per-inch, 262K-color, 10.5-in.diagonal, 1280 x 1024 (SXGA) d isplay has been fabricated using a six-mask process with Cu or Al-allo y thin-film gates. The combination of high resolution and gray-scale a ccuracy has been shown to render color images and text with paperlike legibility. The low-resistivity gate metallization and trilayer-type T FTs with a channel length of 6-8 mu m were fabricated with a six-mask process which is extendible to larger, higher-resolution displays. A c ombination of double-sided driving and active line repair was used so that open gate lines or data lines did not result in visible line defe cts. A flexible drive-electronics system was developed to address the display and characterize its performance under different drive conditi ons.
