Pixel dithering driving method and timing controller using the same

摘要

A pixel dithering driving method and a timing controller using the same are provided. The method uses the N low order bits of M bits together with at least one virtual bit to build several pixel dithering patterns. After the timing controller uses M bits of data received by the timing controller to look up a specific high order bit value, a specific low order bit value, and a specific pixel dithering value corresponding to the M bits in a predetermined gray level look up table and decides the output gray levels according to the specific high order bit value, the timing controller can further select a specific pixel dithering pattern from the pixel dithering patterns mentioned above according to the specific low order bit value and the specific pixel dithering value.
