Abstract:
Provide a set of first RGB (red, green, blue) brightness levels of a set of pixels in a display panel. Generate a set of saturation levels according to the set of first RGB brightness levels. Generate a set of mapping ratios according to the set of saturation levels and the set of first RGB brightness levels. Generate a set of second RGB brightness levels according to the set of first RGB brightness levels and a minimum mapping ratio of the set of mapping ratios. Generate a set of RGBW (red, green, blue, white) brightness levels according to the set of second RGB brightness levels and a set of brightness levels of white sub-pixels of the set of RGBW brightness levels. And convert the set of RGBW brightness levels to generate a set of RGBW gray levels of the set of pixels.
