LUMINANCE COMPENSATION METHOD AND LUMINANCE COMPENSATION DEVICE OF DISPLAY DEVICE, AND DISPLAY DEVICE
First Claim
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.
