ABSTRACT:
A dithering method and apparatus for a liquid crystal display is provided, wherein dithering with frame rate control and dithering without frame rate control can be selectively performed in accordance with the pattern characteristics of the input data to prevent the picture quality deterioration which can result from FRC dithering video data representing specific patterns. The pattern characteristic of the input video data is determined by a phase difference comparison between adjacent video data. A first dithering process is performed on the video data if pattern characteristic of the video data is determined to be a specific pattern, and a second dithering process utilizing a frame rate control is performed on the video data if the pattern characteristic is determined to be a general pattern.
