Abstract
A display module Gamma correction method includes: obtaining corrected Gamma register values corresponding to binding points of a grayscale by correcting register values of s binding points selected from a set of m binding points of the grayscale based on a group of initial Gamma register values that correspond to the m binding points and a target Gamma curve; selecting, from x sets of alternate Gamma register values wherein each set corresponds to m binding points and the initial Gamma register values, a set of Gamma register values used for Gamma correction of the display module(s) as reference register values; and; and correcting register values of remaining m−s binding points based on the reference Gamma register values and the target Gamma curve to obtain a set of target Gamma register values corresponding to the m binding points, wherein s, m and x are all integers greater than one.
