Abstract

The embodiment of the invention relates to a liquid crystal display and its driving method. The liquid crystal display comprises an input logic device, a memory, a determiner and a driver; the input logic device is used for inputting a video signal from a host machine; the memory is used for storing the previous light level and several conditional expressions of the video signal input by the input logic device; the determiner is used for substituting the previous light level stored in the memory and the next light level of the next video signal input to the input logic device into the corresponding condition expressions, so as to determine the output light level; the driver drives every pixel of every frame of image to the liquid crystal unit of the display image on the basis of the output light level determined by the determiner. The embodiment of the invention does not need to confirm if the video signal is dynamic or static state globally, the video signal can be compensated in the manner of overlapping the compensation signals, so as to improve the response delay.

Description

Technical field [0001] The embodiment of the present invention relates to a liquid crystal display and a driving method thereof, and in particular to a liquid crystal display and a driving method thereof that modify a video signal by obtaining an offset according to a conditional expression. Background technique [0002] In recent years, in addition to cathode ray tube (CRT) displays, liquid crystal displays (LCD) have been widely used as image displays and monitors for personal computers (PC) and televisions. LCD is smaller and lighter than CRT monitor. In addition, many improvements have been made to LCD display performance, including low geometric distortion and high image quality. Therefore, liquid crystal displays will be the focus of mainstream display devices used in future video equipment. [0003] However, LCD has a potential problem of poor response time due to poor response characteristics of the liquid crystal itself. That is, among the displays used in the industry,...
