Abstract

The present invention provides a reflective color filter liquid crystal display (10), in the reverse direction of the receiving incident lights, comprising a backplane substrate (200), a reflective electrode layer (210), a planar liquid crystal cell (150), a transparent conductive film (110) and a transparent plate (100) in turn. The transparent plate (100) is adapted for receiving and transmitting the incident light (20). The planar liquid crystal cell (150) is sandwiched between the reflective electrode layer (210) and the transparent conductive film (110). The reflective electrode layer (210) further includes a first band reflective electrode (211), a second band reflective electrode (212) and a third band reflective electrode (213). The backplane substrate (200) comprises a driving circuit (220). The present invention reduces the complexity of LCD and improves optical efficiency without using the color filtering array film in the prior art.

Description

technical field [0001] The invention relates to a spatial modulation color display technology, in particular to a reflective color filter liquid crystal display. Background technique [0002] In recent years, flat panel displays and liquid crystal displays (Liquid Crystal Display, LCD for short) have become mainstream display devices driven by optoelectronic technology and integrated circuit technology. LCD displays have many advantages, including: thin and flat shape, light weight, low operating voltage, low power consumption, full color, and low emissivity. LCD display panels can be classified into transmissive, reflective, and transflective types according to the light emitting mechanism. Reflective LCD displays include liquid crystal projectors and reflective Liquid Crystal On Silicon (LCOS for short). [0003] The substrate planar assembly of the LCD panel includes: a top glass substrate with a transparent conductive film, a liquid crystal planar unit, a pixel electrod...
