Patent ID: 7486266

Claim:
An LCD device, comprising: a memory unit for recording image data of a first frame in a plurality of first blocks, and sequentially recording image data of a second frame in one or more second blocks and at least one of the first blocks with a first frequency; a control unit for time-sequentially dividing the first and second frames into a plurality of sub-frames, respectively, reading image data of the sub-frames from the image data of the first and second frames sequentially with a second frequency recorded in the first blocks and at least one of the second blocks of the memory unit, and sequentially supplying the image data to an LCD panel; and a plurality of back-lights for sequentially generating R, G and B lights according to the image data of the sub-frames, wherein image data of the first frame starts to be read by the control unit when image data of a last sub-frame of the first frame is recorded in the memory unit, and image data of the second frame starts to be read by the control unit when image data of a last sub-frame of the second frame is recorded in the memory unit.
