Abstract
A liquid crystal display that is capable of improving a display quality of the LCD is disclosed, wherein gamma data for controlling the gamma voltage is stored for each of at least two modes. The gamma data for each mode is accessed in response to a selected mode, and n gamma voltages (wherein n is an integer), each having a different voltage level, indicated by the gamma data in the selected mode are generated. A lookup table is provided in which a color temperature correction data for correcting a color temperature characteristic of an input image is set in correspondence with a gray level value of the input image. The lookup table is accessed to read out color temperature correction data corresponding to the gray level value of the input image. The data lines are driven by the color temperature correction data.
