Title:
TRANSFLECTIVE LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/037286
Kind Code:
A1
Abstract:
A transflective liquid crystal display device adopts designs of a COA and a BPS, and a reflecting electrode (270) is provided on a black matrix (251) of a BPS light shield layer (250), and the reflecting electrode (270) is connected with a pixel electrode (260), so that the device forms a reflecting region in a region corresponding to the reflecting electrode (270), and forms a transmissive region in the region corresponding to the pixel electrode (260); the brightness of a display frame is improved when external light intensity is high, and the reflecting region does not occupy the area of the transmissive region, and the transmittance of the device would not be affected; moreover, the thickness of a liquid crystal cell of the reflecting region and the transmissive region can be controlled by controlling the thickness of the black matrix without introducing an additional insulation layer, and the structure is simple.
