Abstract

The invention provides a method of sub-pixel compensation coloring of a RGBW display device based on edge pixel detection, including: receiving m sets of high-resolution RGB data; converting the m sets of high-resolution RGB data into m sets of RGBW data, RG sub-pixels and BW sub-pixels of the RGBW display device each being corresponding to one set of RGBW data; judging a nine-palace pixel block of the RGBW display device whether contains an edge pixel based on the high-resolution RGB data; if the nine-palace pixel block contains the edge pixel, judging the nine-palace pixel block whether contains a saturation pixel based on the high-resolution RGB data; and if the nine-palace pixel block contains the saturation pixel, using a first filtering method to perform a filtering processing on a center pixel in the nine-palace pixel block based on the RGBW data. The invention can effectively eliminate color aliasing phenomenon.
