1. a luminance compensation method for display device, is characterized in that, the method comprises:

  • For each sub-pixel corresponding with display device in input picture, specifically carry out;

    Obtain the input GTG value of current sub-pixel, and the funtcional relationship corresponding with current sub-pixel;

    Described funtcional relationship is;

    in advance for each sub-pixel of display device, and the corresponding relation of the GTG value after the compensation that determine, that this sub-pixel is corresponding of the test brightness value according to this sub-pixel under the test pattern of multiple different GTG values and target brightness value and input GTG value;

    Utilize the input GTG value of this sub-pixel and corresponding described funtcional relationship, obtain the GTG value after compensation that this sub-pixel is corresponding, according to the GTG value after compensation, this sub-pixel is carried out to luminance compensation.
