The invention provides a paper white reflective wide-viewing-angle liquid crystal display and a key process thereof. The liquid crystal display comprises upper ITO glass, lower ITO glass, liquid crystal, an upper polaroid, a lower polaroid and a frame. The liquid crystal is embedded in the frame, the upper ITO glass and the lower ITO glass are arranged on the upper face and the lower face of the liquid crystal respectively, the upper polaroid is arranged on the upper side of the upper ITO glass on the upper portion, and the lower polaroid is arranged on the lower side of the lower ITO glass onthe lower portion. Two layers of compensation films, namely a first layer of compensation film and a second layer of compensation film, are sequentially adhered to the lower part of the upper polarizer from top to bottom, the compensation included angle between the first layer of compensation film and the second layer of compensation film being 45 degrees, and the compensation included angle between the first layer of compensation film and the upper polarizer being 90 degrees. Effective matching of the two layers of compensation films and the liquid crystal is utilized, the double compensation effect on the color and the visual angle of an STN product can be achieved, the appearance color of the product can be made to be paper white, and meanwhile wide-visual-angle display is achieved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a paper-white reflective wide viewing angle liquid crystal display and its key technology. Background technique [0002] A liquid crystal display is a widely used flat-panel display, featuring low power consumption, thin profile, light weight, and low driving voltage. The liquid crystal display itself cannot emit light, and relies on the modulation of external light to achieve display. Conventional liquid crystal display methods include TN display mode suitable for low-channel number drive, STN display mode suitable for high-channel number drive, and high-contrast VA display mode. TN LCDs are white in color and can only be driven by low channels; FSTN LCDs are suitable for high-channel drives, and the color is yellowish or bluish; paper-white FSTN LCDs can be used in high-channel drives, and the color paper is white, but the viewing angle is relatively narrow. n...
