Abstract
A gamma correction device and method thereof is described herein, in which gray-scale voltages may be generated that correspond with a plurality of gamma values. The gray-scale voltages may be generated by adjusting output ranges of the gray-scale voltages while fixing a gamma correction voltage on a constant level. The gamma correction device may include a gamma correction voltage generator generating a plurality of gamma correction voltages corresponding to a reference gamma value; a gray-scale voltage generation circuit dividing the gamma correction voltages to generate a plurality of sub gray-scale voltage sets each of which includes a sub gray-scale voltage corresponding to each gamma value; and a gray-scale voltage selection circuit outputting one of the sub gray-scale voltages of each sub gray-scale voltage set as a gray-scale voltage.
