Abstract
A method for optimizing image quality and a module for optimizing image quality are provided. The method includes: in a gamma adjustment phase, controlling and setting respective actual data voltages corresponding to a grey scale 0 of sub-pixels having different colors, and controlling at least two of the actual data voltages corresponding to the grey scale 0 of the sub-pixels having different colors to be different from each other, to control a gamma curve of the sub-pixels to make an absolute value of a luminance difference between the luminance of the gamma curve corresponding to each grey scale value and the luminance of a standard gamma curve corresponding to the grey scale value less than a predetermined luminance difference; and in a display phase, when a grey scale value provided to sub-pixels having different colors is 0, applying the corresponding actual data voltages to the sub-pixels having different colors.
