Abstract: A liquid crystal display includes a plurality of gate lines and a plurality of data lines crossing over the gate lines while being electrically insulated from the gate lines. Pixels are placed at the cross regions of the gate and the data lines arranged in a matrix form. Each pixel has a switching circuit connected to the gate and the data lines. Data voltages are fed to the pixels such that the polarity of the pixels is inverted per a pixel group of two or more pixel rows. Gate voltages are applied to the neighboring first and second pixel groups such that the gate voltage applied to the pixel row of the first pixel group close to the second pixel group differs from the gate voltage applied to the pixel row of the first pixel group distant to the second pixel group.

Abstract: A gamma voltage generator for a liquid crystal display (LCD) capable of removing residual images by compensating a gamma voltage is presented. The gamma voltage generation apparatus adjusts the common voltage by the kickback voltage for the intermediate gray level, and tunes the gamma voltages other than the intermediate gray level gamma voltage. The adjustment of the gamma voltages other than the intermediate gray level gamma voltage is achieved in such a manner that the difference between the intermediate gray level kickback voltage and the kickback voltage at one of the gray levels other than the intermediate gray level is equal to half of the difference between the sum of the two inverted gamma voltages representing the intermediate gray level gamma voltages and the sum of the two inverted gamma voltages corresponding to the selected gray level.
