Abstract
A liquid crystal display includes a plurality of sub-pixels arranged in an array. A method of driving the liquid crystal display includes determining a frame rate weight according to a current frame rate of a plurality of image frames, performing linear prediction according to the current frame rate to generate an initial overdrive value of a sub-pixel, selecting an error correction value according to a previous gray level of the sub-pixel, generating an overdrive weight according to the previous gray level and a current gray level of the sub-pixel, generating an overdrive offset according to a product of the error correction value, the frame rate weight and the overdrive weight, combining the initial overdrive value and the overdrive offset to generate a corrected overdrive value, and driving the sub-pixel according to the corrected overdrive value.
