Paper Abstract

Recent development and application of TFT-LCDs using a-Si TFT are reviewed. An in-plane- switching (IPS) mode LCD is expected to be the most promising among many candidates for economically improving the poor-viewing angle in an LCD. Our practically-unlimited viewing-angle 14.5-inch IPS TFT-LCD prototype is described, which has XGA resolution and 64-gray-scale capability. An aircraft cockpit display requires a wide viewing-angle, wide operating-temperature, and high readability. Our large-size and full-color TFT-LCD under production as a cockpit display for new types passenger plane is described. A large-size reflective-color TFT-LCDs prototype fabricated through our high-aperture-ratio technology and minimized-production process is describe. A reflective TFT-LCD is very suitable for reducing power consumption. Additionally, performance and characteristics of other TFT- LCD prototypes and products are described.
