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.
