Abstract
An image processing method of a display includes transforming three color image data to four color image data, passing the four color image data through a kernel filter to generate original data corresponding to a first sub pixel and a second sub pixel, and transforming original data of each sub pixel to generate display data of the sub pixel. The original data of the first sub pixel is the same as the original data of the second sub pixel. The brightness of the display data of the first sub pixel is substaintially greater than the original data of the first sub pixel. The brightness of the display data of the second sub pixel is substaintially smaller than the original data of the second sub pixel.
