1. A luminance compensation method of a display device, comprising:

  • obtaining an input grayscale value of one of a plurality of sub-pixels corresponding to the display device of an input image, and obtaining a functional relationship between a compensated grayscale value and the input grayscale value corresponding to the sub-pixel;

    obtaining the compensated grayscale value corresponding to the sub-pixel by using the functional relationship, and performing luminance compensation on the sub-pixel according to the compensated grayscale value; and

    executing the above operations repeatedly for each of the plurality of sub-pixels of the input image;

    wherein the functional relationship is determined for each of the sub-pixels of the display device, according to a test luminance value and a target luminance value of the sub-pixel under a plurality of test a terns of different test grayscale values.
