Abstract
A gamma correction apparatus for a liquid crystal display comprises a reference voltage generating circuit and a gamma correction circuit. The reference voltage generating circuit outputs a plurality of reference voltages according to the pixel data. The gamma correction circuit gamma-corrects the pixel data according to the reference voltages. The feature of the invention resides in that the reference voltage generating circuit outputs the corresponding reference voltages to gamma-correct the pixel data according to the positions of the pixels corresponding to the pixel data in the LCD monitor and the display colors of the pixels.
