Abstract:
1. A method for driving a display device, the method comprising: providing a pixel comprising a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel; generating a display signal for the pixel and providing at least a first luminance weighting and a second luminance weighting corresponding to the display signal, wherein each of the first luminance weighting and second luminance weighting comprises luminance weightings of the red, green, blue, and white sub-pixels, and a fixed ratio of the luminance weightings of the red, green, blue, and white sub-pixels in the second luminance weighting to the luminance weightings of the red, green, blue, and white sub-pixels in the first luminance weighting is inversely proportional to a ratio of light transmittances of color absorption areas of a color filter substrate corresponding to the red, green, blue, and white sub-pixels; and utilizing one of the first luminance weighting and the second luminance weighting to drive the pixel.
