Abstract: A liquid crystal display (LCD) device includes: a data source, for generating a N-bit pixel data, N being a positive integer; a digital gamma correction unit, coupled to the data source, for performing digital gamma correction on the pixel data to generate a (N+M)-bit digital gamma correction pixel data, M being a positive integer; an image dithering unit, coupled to the digital gamma correction unit, for performing image dithering on the digital gamma correction pixel data to generate a (N+M−K)-bit dithering compensation pixel data, K being a positive integer; and a converter, coupled to the image dithering unit, for converting the dithering compensation pixel data into an output image. A bit number of the converter is lower than a bit number of the digital gamma correction unit.
