Abstract

Provided are a liquid crystal display and a drive method therefor. The liquid crystal display (100) comprises an input logic device (110), a memory (120), a light sensor (170) and an integrator (180), wherein the input logic device (110) is used for inputting a video signal from a host, and the video signal is kept in a turned-on state; the memory (120) is used for storing a static state brightness level; the light sensor (170) is used for sensing the brightness of the video signal to generate a light sensing signal; and the integrator (180) is used for integrating the light sensing signal, and turning off the video signal by means of corresponding to an integration result satisfying the static state brightness level.

Description

technical field [0001] Embodiments of the present invention relate to a liquid crystal display and its driving method, in particular to a liquid crystal display and its driving method which modifies the video signal by sensing the brightness and integrating the light sensing signal to meet the brightness level of the static state and then turning it off. method. Background technique [0002] In recent years, in addition to cathode ray tube (CRT) displays, liquid crystal displays (LCDs) have been widely used as image displays and displays for personal computers (PCs) and televisions. LCDs are smaller and lighter than CRT monitors. In addition, many improvements have been made to the display performance of LCDs, including low geometric distortion and high image quality. Accordingly, liquid crystal displays will be the focus of mainstream display devices used in future video equipment. [0003] However, LCDs have a potential problem of poor response time due to poor response...
