Abstract:
1. A driving method of an image display device including an image display panel configured of a signal processing unit, the method causing the signal processing unit with regard to a first pixel with regard to a second pixel with regard to a fourth sub-pixel the method comprising: obtaining the maximum value V obtaining a reference extension coefficient α determining an extension coefficient α wherein the saturation S and luminosity V(S) are represented with where Max denotes the maximum value of three sub-pixel input signal values of a first sub-pixel input signal value, a second-sub pixel input signal value, and a third sub-pixel input signal value as to a pixel, and Min denotes the minimum value of three sub-pixel input signal values of the first sub-pixel input signal value, the second-sub pixel input signal value, and the third sub-pixel input signal value as to the pixel.
