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.

Gamma correction method, gamma correction device and gamma correction system

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.
