Liquid crystal display, drive circuit, and drive method

Abstract

A driving circuit of liquid crystal display consists of multiple parallel scanning line, multiple parallel data line being crossed with said scanning lines separately, a scan-driving circuit for driving said scanning line, a data driving circuit for providing data signal to multiple data line, a control circuit for controlling two said driving circuits and for generating multiple voltage signal to compensate grey scale, and a light sensing element being set between two base plates and being electric-connected to control circuit.

Description

【Technical field】 [0001] The invention relates to a driving circuit capable of alleviating screen display flicker, a liquid crystal display using the driving circuit and a driving method of the liquid crystal display. 【Background technique】 [0002] Liquid crystal display has the characteristics of light and thin, low power consumption and less radiation, so it is widely used in fields such as notebook computers, mobile phones and portable computers. [0003] see figure 1 , is a schematic diagram of a liquid crystal display in the prior art. The liquid crystal display 100 includes an upper glass substrate (not shown), a lower glass substrate (not shown) placed opposite to the upper glass substrate, a liquid crystal layer (not shown) between the two glass substrates, a The scan driving circuit 110 , a data driving circuit 120 and a control circuit 130 . [0004] The lower glass substrate includes a plurality of scanning lines 101 parallel to each other, a plurality of data...
