摘要： A liquid crystal display includes a timing controller (200) and a liquid crystal panel (100). The timing controller (200) sequentially receives first through third primitive image signals (DAT1,DAT2,DAT3) and sequentially outputs first through third corrected image signals (DAT1',DAT2',DAT3'). The liquid crystal panel (100) displays an image based on the first through third corrected image signals (DAT1',DAT2',DAT3'). The timing controller (200) generates a first converted image signal (tDAT1) having a first gray level based on the first primitive image signal (DAT1) and stores the first converted image signal (tDAT1). The second primitive image signal (DAT2) has a second gray level and the timing controller (200) generates a second converted image signal (tDAT2) having a third gray level higher than the second gray level when the second gray level is lower than the first gray level. The timing controller (200) generates the third corrected image signal (DAT3') using the second converted image signal (tDAT2) and the third primitive image signal (DAT3).
