Claim 4:
5. The method according to claim 4, wherein the four reference sub-display areas comprise a first reference sub-display area, a second reference sub-display area, a third reference sub-display area and a fourth reference sub-display area, and calculating the weighted sum of the average luminance values of the reference sub-display areas under the target grayscale value with the weight factors for the reference sub-display areas to obtain the target luminance value of the target sub-pixel under the target grayscale value further comprises:
calculating the target luminance value according to formula (2):

LX=L1×f1+L2×f2+L3×f3+L4×f4  formula (2)

wherein LX represents the target luminance value, L1 represents an average luminance value of the first reference sub-display area, f1 represents a weight factor for the first reference sub-display area, L2 represents an average luminance value of the second reference sub-display area, f2 represents a weight factor for the second reference sub-display area, L3 represents an average luminance value of the third reference sub-display area, f3 represents a weight factor for the third reference sub-display area, L4 represents an average luminance value of the fourth reference sub-display area, and f4 represents a weight factor for the fourth reference sub-display area.
