ABSTRACT:
An apparatus for converting a digital pixel signal to a gamma voltage signal for a pixel in a liquid crystal display (LCD), wherein the digital pixel signal corresponds to the pixel. The apparatus includes a pixel signal converting unit for converting the digital pixel signal to a converted pixel signal and a gamma correction unit coupled to the pixel signal converting unit for outputting the gamma voltage signal according to the converted pixel signal. The relation between the digital pixel signal and the converted pixel signal is determined according to a display color of the pixel.
