Abstract

This invention relates to one optical compensation curve LCD device, which comprises one LCD panel, one Gamma correction unit, one public voltage generation unit, one grating drive unit and one data signal switch unit, wherein, the grating drive unit comprises one high voltage generation circuit with higher voltage than the correction unit; the LCD panel comprises one pixel electrode and one public electrode; the data signal switch unit is connected to the high voltage generation circuit, correction unit and panel to provide the voltage signals of the Gamma correction unit to the pixel electrode.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display, in particular to an optically compensated curved liquid crystal display. 【Background technique】 [0002] At present, liquid crystal displays have gradually replaced traditional cathode ray tube (Cathode Ray Tube, CRT) displays used in calculators, and because liquid crystal displays are light, thin, and small, they are very suitable for use in desktop computers, Personal digital assistant (Personal Digital Assistant, PDA), portable phone, TV and various office automation and audio-visual equipment. [0003] In order to increase the viewing angle of the liquid crystal display, an optically compensated bend technology (Optically Compensated Bend, OCB) is proposed in the industry, which realizes self-compensation of the viewing angle by designing the arrangement of liquid crystal molecules. The liquid crystal molecules using OCB technology are in a bent state (Bend Type), and their arrangement ...
