Liquid crystal displays used in avionics applications are required to have high luminance, good color saturation, low reflection, good contrast ratio and gray scale separation in a wide range of viewing angle. In this paper, several unique solutions are provided to achieve these stringent requirements. In order to reduce display reflection under high ambient light, OIS proprietary multilayer inorganic black matrix is deposited using plasma-enhanced CVD technique and the specular reflection of final display is measured to be less than 0.6%. High display luminance and good color saturation are achieved through increasing pixel opening to be more than 65% by using OIS patented high aperture TFT design. The viewing angle is improved using OIS patented retardation film laminated on the rear side of display. Excellent gray shade linearity and contrast ratio over +or-60 degrees horizontal and -15 degrees /+40 degrees vertical viewing envelope is demonstrated. Finally, a 6.25'x6.25' full color LCD with 512x512 resolution is developed based on these new technologies.
