Abstract
A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. This novel configuration effectively decouples the liquid crystal cell and other optical elements behind the front fiber optic faceplate from the angular orientation of the viewer with respect to the display. The liquid crystal display described in this invention further provides a high quality color display, without viewing parallax, using a color selection filter mosaic outside of the liquid crystal cell. The display also increases luminous efficiency and improves color saturation by concentrating the transmission of available backlight illumination through the use of a rear fiber-optic faceplate and a second rear-mounted mosaic of color interference filters.
