ABSTRACT:
An apparatus set in a liquid crystal display (LCD) for executing gamma correction is disclosed. The gamma voltage signal is for inputting to a pixel. The digital pixel signal is an M-bit binary signal. The gamma correction executing apparatus includes a pixel signal converting device for converting the digital pixel signal to a converted pixel signal and a gamma correcting device coupled to the pixel signal converting device for outputting the gamma voltage signal according to the converted pixel signal. The converted pixel signal is an N-bit binary signal, and N is larger than M. The relation between the digital pixel signal and the converted pixel signal and the relation between the converted pixel signal and the gamma voltage signal are determined according to the displaying color of the pixel.
