1. An image processing method of a display, comprising:

  • transforming a three color image data to a four color image data;

    the four color image data passing through a kernel filter to generate original data corresponding to a first sub pixel, a second sub pixel, a third sub pixel, and a fourth sub pixel disposed in sequence, wherein the second sub pixel is adjacent to the first sub pixel and the third sub pixel, the third sub pixel is adjacent to the fourth sub pixel, and the first sub pixel, the second sub pixel, the third sub pixel, and the fourth sub pixel are sub pixels with different colors;

    transforming an original data of the first sub pixel to generate a first display data of the first sub pixel, wherein a brightness of the first display data of the first sub pixel is substaintially greater than a brightness of the original data of the first sub pixel;

    transforming an original data of the second sub pixel to generate a first display data of the second sub pixel, wherein a brightness of the first display data of the second sub pixel is substaintially smaller than a brightness of the original data of the second sub pixel;

    transforming an original data of the third sub pixel to generate a first display data of the third sub pixel, wherein a brightness of the first display data of the third sub pixel is substaintially greater than a brightness of the original data of the third sub pixel;

    transforming an original data of the fourth sub pixel to generate a first display data of the fourth sub pixel, wherein a brightness of the first display data of the fourth sub pixel is substaintially smaller than a brightness of the original data of the fourth sub pixel; and

    displaying a first frame of image on the display according to the first display data of the first sub pixel, the first display data of the second sub pixel, the first display data of the third sub pixel, and the first display data of the fourth sub pixel.
