An optical adjustment method and an optical adjustment device for a display panel, and a display device are provided. The optical adjustment method includes: displaying N groups of testing images sequentially on the display panel, each group of testing images including M images distributed at different display regions of the display panel, each image corresponding to one to-be-adjusted reference color, N being an integer greater than or equal to 1, M being an integer greater than or equal to 1; and when each group of testing images are displayed on the display panel, detecting, by an optical detection unit, optical parameters of the M images in the group of testing images simultaneously, and performing optical adjustment on the display panel in accordance with the optical parameters.

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&#x2212;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.
