一种液晶显示器，包括：一资料来源，用以产生N位元的一画素资料，N为正整数；一数位珈玛校正单元，耦接至该资料来源，用以对该画素资料进行数位珈玛校正以产生(N+M)位元的一数位珈玛校正画素资料，M为正整数；一影像递色单元，耦接至该数位珈玛校正单元，将该数位珈玛校正画素资料进行影像递色补偿成(N+M-K)位元的一递色补偿画素资料，K为正整数；以及一转换单元，耦接至该影像递色单元，将该递色补偿画素资料转换成一输出影像，其中，该数位类比转换单元的位元数低于该数位珈玛校正单元的位元数。; 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 bit number of the digital gamma correction unit. |
