1. A method for determining a compensation grayscale, the method comprising:
dividing a display area of a display panel into a plurality of sub-display areas distributed in an array;
selecting at least two sub-display areas from the plurality of sub-display areas as reference sub-display areas, wherein the reference sub-display areas are adjacent to each other and one of the reference sub-display areas comprises a target sub-pixel to be compensated;
determining a weight factor for each of the reference sub-display areas according to a distance between a center point of the target sub-pixel and a center point of each reference sub-display area and a distance between center points of adjacent reference sub-display areas;
calculating a weighted sum of average luminance values of the reference sub-display areas under a target grayscale value with the weight factors for the reference sub-display areas to obtain a target luminance value of the target sub-pixel under the target grayscale value; and
determining a compensation grayscale value of the target sub-pixel under the target grayscale value according to the target luminance value.
