Abstract

The present invention relates to an optically compensated curved liquid crystal display, which includes a liquid crystal display panel, a gamma correction unit, a common voltage generation unit, a gate drive unit and a data signal switch unit. The gate driving unit includes a gate signal generating circuit and a high voltage generating circuit, the gate signal generating circuit is used to generate a gate driving signal, and the output voltage of the high voltage generating circuit is higher than that generated by the gamma correction unit maximum voltage. The liquid crystal display panel includes a pixel electrode and a common electrode. The data signal switching unit is respectively connected with the high voltage generating circuit, the gamma correction unit and the liquid crystal display panel, and can selectively provide the voltage signal of the high voltage generating circuit or the gamma correction unit to the pixel electrode. The optical compensation curved liquid crystal display of the invention has short initialization time and low cost.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display, in particular to an optical compensation curved liquid crystal display. 【Background technique】 [0002] At present, liquid crystal displays have gradually replaced the traditional cathode ray tube (CRT) displays used in calculators. Moreover, due to the characteristics of light, thin and small liquid crystal displays, they are very suitable for use in desktop computers, Personal digital assistant (Personal Digital Assistant, PDA), portable telephone, television and various office automation and audio-visual equipment. [0003] In order to increase the viewing angle of the liquid crystal display, the industry proposes an optically compensated bending technology (Optically Compensated Bend, OCB), which realizes the 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), w...
