Abstract
A 3.3-inch 1.9 M-pixel poly-Si TFT-LCD for high-definition and compute r-data projectors has been developed. This LCD is able to display both full-band HD signals and computer data. This unique applicability is realized by adapting novel CMOS decoder circuits integrated on the sub strate. By arranging these decoder circuits on both sides of the panel , effective redundancy is also realized.An oxidation thinning process and a low-resistance tungsten-polycide gate electrode are used in fabr icating the poly-Si TFTs, and n-channel MOS-TFT mobility of 160 cm(2)/ Vs was realized. A horizontal resolution of 1000 TV lines and a contra st ratio of 200:1 is achieved.
