Zusammenfassung:A driving method for a liquid crystal display includes the following steps: before the switching operation from a preceding frame to a next frame, looking up a preset second lookup table to obtain an actual gray scale of the preceding frame based on frame data of the preceding frame, the frame data of the preceding frame at least includes gray scale; according to the actual gray scale of the preceding frame and a predetermined gray scale of the next frame, looking up a preset first lookup table to obtain an overdrive gray scale for the switching operation from the preceding frame to the next frame ; performing an overdrive operation according to the overdrive gray scale. With the driving method, the gray scale can be corrected by the second lookup table, which improves the display effect of the liquid crystal display.
