Reflective liquid crystal panel and refractive index matching euphotic electrode layer

Abstract

The invention discloses a reflective liquid crystal panel, which comprises a light-tight substrate, a patterned electrode layer, a first alignment film, a liquid crystal layer, a second alignment film, a refractive index matching euphotic electrode layer and a euphotic substrate. The patterned electrode layer is arranged on the light-tight substrate. The first alignment film is arranged on the patterned electrode layer. The liquid crystal layer is arranged on the first alignment film. The second alignment film is arranged on the liquid crystal layer. The refractive index matching euphotic electrode layer is arranged on the second alignment film. The euphotic substrate is arranged on the refractive index matching euphotic electrode layer. The refractive indexes of the first alignment film, the second alignment film, the refractive index matching euphotic electrode layer and the euphotic substrate are matched with each other to promote the proportion of the light reflected by the patterned electrode layer, wherein the light is incident from the euphotic substrate. The invention also discloses the refractive index matching euphotic electrode layer.

Description

technical field [0001] The present invention relates to a display panel and its electrode layer, and in particular to a reflective liquid crystal panel and its refractive index matching light-transmitting electrode layer. Background technique [0002] A liquid crystal on silicon (LCOS) panel is a display panel manufactured on the basis of a silicon wafer, which uses a metal-oxide-semiconductor transistor (MOS transistor) to replace the existing A thin film transistor arranged on a glass substrate in a liquid crystal panel. The liquid crystal on silicon panel is a reflective display panel, and its pixel electrodes are made of opaque metal materials. In addition, because the metal pixel electrodes almost cover the entire pixel area, compared with the conventional liquid crystal panel whose transparent pixel electrodes only cover part of the pixel area, the LCD on Silicon panel can make full use of the light source to increase the brightness of the display screen.

Problems solved by technology

[0004] Since the refractive index of each optical film layer is not the same, when light passes through the interface of two optical film layers with different refractive indices, part of the light will be reflected at the interface and cannot reach the patterned metal electrode layer, or cannot be received. The patterned metal electrode layer is reflected to the outside world, which will reduce the light efficiency and affect the display quality of the liquid crystal on silicon panel
