摘要： A gamma correction method applied to a display screen to be debugged includes: for a color of the display screen to be debugged, arranging a plurality of reference points, arranging at least one transition point between two adjacent reference points, and obtaining a brightness adjustment curve representing a corresponding relationship between a brightness adjustment value and a gamma band according to the plurality of reference points and the at least one transition point. Each gamma band represents a set of register values corresponding to gray scales of the color at the brightness adjustment value corresponding to the gamma band.

摘要： The present disclosure discloses a method and device for correcting display brightness of a display module and a display module. The method includes: receiving target brightness of the display module; determining target brightness components of sub-pixels of various colors corresponding to the target brightness according to a chromaticity coordinate of the target brightness and characteristics of luminescence of the sub-pixels of various colors in the display module; determining an initial gamma register value according to the target brightness components of the sub-pixels of various colors corresponding to the target brightness; performing gamma correction on the display module according to the initial gamma register value, and detecting the display brightness; and in response to determining that a difference value between the display brightness and the target brightness exceeds a first preset range, correcting the display brightness by adjusting the initial gamma register value according to the difference value.
