Claim:
1. A method of sub-pixel compensation coloring of a RGBW display device based on edge pixel detection, RG sub-pixels and BW sub-pixels of the RGBW display device each being corresponding to a set of high-resolution RGB data; the method comprising: receiving m sets of high-resolution RGB data, wherein m is a positive integer; converting the m sets of high-resolution RGB data into m sets of RGBW data, wherein RG sub-pixels and BW sub-pixels of the RGBW display device each are corresponding to one of the m sets of the RGBW data; processing the m sets of RGBW data to obtain processed m sets of RGBW data, wherein processing the m sets of RGBW data comprises steps of: using the processed m sets of RGBW data to display by the RGBW display device; wherein the step of judging a nine-palace pixel block of the RGBW display device whether contains an edge pixel based on the high-resolution RGB data comprises: wherein the step of further judging the nine-palace pixel block whether contains a saturation pixel based on the high-resolution RGB data comprises:
