We have developed a 20.1-inch Diagonal SXGA (1280 x 1024) TFT-LCD which possesses high aperture ratio of 72%. We have adopted very-high-aperture-ratio (Super-HA) technology using pixel-on-organic-passivation structure and very-wide-viewing-angle (Super-VA) technology achieved by simulating and optimizing the optical parameters of LCD cells and optical compensating layers in this TFT-LCD. We have accomplished power consumption as low as 25W with 200cd/m2 luminance. These LCD monitors possess sufficient picture image quality for high-end graphics applications: CAD/CAM, CG, DTP etc.for replacement of CRT monitors.
