Patent ID: 7884791

Claim:
An over driving method for a liquid crystal display, wherein the liquid crystal display includes a plurality of pixels to form a pixel matrix and each the pixel having a thin film transistor, comprising: providing a modifier having a plurality of gray-level value look up tables, wherein each of the look up tables directly corresponds to one row number signal that indicates a row number of a pixel which row the pixel is located in the pixel matrix, and each row number signal only corresponds to one of the look up tables; inputting a first gray-level value, a second gray-level value and the row number signal to the modifier; directly using the row number signal to search one of the look up tables that directly corresponds to the row number signal; obtaining a corrected gray-level value based on the look up table directly corresponding to the row number signal, the first gray-level value and the second gray-level value; determining an over driving voltage based on the corrected gray-level value; and sending the over driving voltage to control the thin film transistor of the pixel located in the row number of the pixel matrix.
