Abstract
A liquid crystal on silicon display device is provided. Multiple grey levels of a pixel are transformed into multiple color values. The grey levels respectively correspond to multiple first sub-pixels. For each of the first sub-pixels, at least one parameter of a reflectance fitting function is obtained according to the color values, a gamma correction is performed according to the corresponding grey level to obtain a reflectance, and a pixel voltage is calculated according to the at least one parameter and the reflectance. The pixel voltage is applied to a pixel electrode of the corresponding first sub-pixel.
