Problems solved by technology

Although the transflective liquid crystal display device can perform transflective display, due to the existence of the reflective region 201', the transmittance of the liquid crystal display device is seriously affected, and it is necessary to control the thickness of the insulating layer 220' to realize the liquid crystal layer 300 The thickness 'in the reflective area 201' is half of the thickness in the transmissive area 202', the process is complicated and difficult to realize

Abstract

The invention provides a transflective liquid-crystal display device. The transflective liquid-crystal display device adopts COA and BPS design, a reflecting electrode is arranged on a black matrix of a BPS shading layer and is connected with a pixel electrode, so that the device forms a reflecting zone in an area corresponding to the reflecting electrode and forms a transflective zone in an area corresponding to the pixel electrode, the brightness of display pictures is improved when outside light intensity is large, the reflecting zone does not occupy the area of the transflective zone, and the transmittance rate of the device is not affected. In addition, the liquid crystal box thickness in the reflecting zone and the transflective zone can be controlled by controlling the thickness of the black matrix without introduction of an additional insulation layer, and the transflective liquid-crystal display device is simple in structure.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a transflective liquid crystal display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] At present, liquid crystal displays on the market are roughly divided into three types according to the demand for light source, transmissive liquid crystal display, reflective liquid crystal display and transflective liquid crystal display. Among them, the transmissive liquid crystal display uses the backlight module on the back of the liquid crystal panel as the light source, and the light emitted by the backlight module passes ...
