1. A method for generating target grayscale values, comprising steps of:
obtaining a plurality of gamma curves corresponding to a plurality of refresh rates, each of the plurality of gamma curves defining by a correlation between brightness values and grayscale values;
determining, according to different brightness values corresponding to each grayscale value at different refresh rates, a grayscale compensation value corresponding to each grayscale value at each refresh rate difference; wherein the refresh rate difference is a difference between two different refresh rates; and
determining, through performing a forward operation based on each grayscale value combined with an absolute value of a corresponding grayscale compensation value, a plurality of target grayscale values.
