1. A pixel compensation method, comprising:
driving a pixel unit to be compensated that needs to be pixel compensated to emit light;
obtaining real optical sensing data of the pixel unit to be compensated, wherein the pixel unit to be compensated comprises a first subpixel and a second subpixel disposed adjacent to the first subpixel, and the first subpixel is provided with a sensing part configured to sense brightness intensity;
determining first compensation data for the first subpixel according to the real optical sensing data; and
determining second compensation data for the second subpixel according to the first compensation data;
wherein the real optical sensing data comprises first real optical sensing data for the first subpixel, and the step of determining first compensation data for the first subpixel according to the real optical sensing data comprises:
generating a gray-scale-brightness characteristic curve associated with the first subpixel according to the first real optical sensing data; and
determines the first compensation data of the first subpixel according to the gray-scale-brightness characteristic curve associated with the first subpixel;
wherein the real optical sensing data comprises second real optical sensing data for the second subpixel, and the step of determining the second compensation data for the second subpixel according to the first compensation data comprises:
taking the second subpixel that needs to be compensated currently as a center pixel to be compensated;
obtaining compensation reference data for M compensation reference pixels adjacent to the center pixel to be compensated, wherein the M compensation reference pixels comprises the first subpixel, the compensation reference data comprises the first compensation data, and M is a natural number;
determining center compensation data for the center pixel to be compensated according to the compensation reference data for the M compensation reference pixels; and
taking the center compensation data as the second compensation data for the second subpixel that needs to be compensated currently.
