Patent ID: 8013830

Claim:
A liquid crystal display, comprising: a liquid crystal display panel having a plurality of liquid crystal molecules and a plurality of horizontal display areas, each of the horizontal display areas including a plurality of pixels in a row; a backlight module, comprising a plurality of linear lighting devices respectively corresponding to the pixels in each of the horizontal display areas; a dimming control unit for generating a plurality of dimming control signals, each of the dimming control signals having a dimming frequency, the dimming frequency of each of the dimming control signals being higher than a frame rate of the liquid crystal display panel and the dimming frequency of each of the dimming control signals being a multiple of the frame rate, wherein the dimming control unit adjusts a phase of each of the dimming control signals such that each of the dimming control signals is delayed by a period of delay time one by one; a backlight module driving circuit for periodically driving the linear lighting devices in sequence according to the plurality of dimming control signals, and a scan driver for outputting a scan signal such that the liquid crystal molecules of the pixels in each of the horizontal display areas reach a maximum transmission at a maximum time, and a difference between each maximum time of each horizontal display area equals the delay time.
