Patent ID: 8054268

Claim:
A liquid crystal display (LCD) comprising an LCD panel, the LCD further comprising: a frame memory configured for receiving a plurality of first gradations of a current frame to be displayed and outputting a plurality of second gradations of a preceding frame pre-stored therein; a comparator configured for receiving the first gradations of the current frame and the second gradations of the preceding frame, and comparing the first gradations with the second gradations to generate a comparison result; a luminance detector configured for detecting a luminance degree of each of pixels of the LCD panel displaying in the current frame according to the first gradations of the current frame, the luminance degrees of the LCD panel being divided into X levels, where X≧2 and X is a natural number; a calculator configured for calculating a degree of complication of a picture to be displayed in the current frame, the complication degrees of displays to be displayed on the LCD panel are divided into Y levels, where Y≧2 and Y is a natural number; and a gradation processor configured for receiving the first gradations of the current frame to be displayed on the LCD panel, generating a plurality of pairs of compensating gradations according to the first gradation of each pixel, and each pair of the compensating gradations selected from X+Y pairs of compensating gradations to be outputted to a corresponding pixel of the LCD panel according to the comparison result, a received luminance degree corresponding to the pixel, and the complication degree; wherein the calculator is further configured for providing the complication degree to the gradation processor; wherein the LCD panel comprises a plurality of display areas defined thereof, each display area comprising a sub-pixel matrix, the complication degree being calculated by summing up gradations of the current frame to be provided to each sub-pixel matrix.
