Display adjusting method based on asymmetric gamma display module

The invention discloses an asymmetric display-based adjustment method, which comprises the following steps of: initializing a display picture of a to-be-adjusted display module to obtain an original adjustment picture; performing image residue preprocessing on the original adjustment picture to obtain a corresponding target adjustment picture; comparing the target adjustment picture with the original adjustment picture, and determining picture residue distribution in the target adjustment picture; according to the picture residue distribution, determining an offset voltage amount corresponding to the target adjustment picture; and adjusting the gamma voltage, the L0 voltage and the L255 voltage of the display module to be adjusted according to the offset voltage amount or the picture residual distribution. According to the invention, on the basis of asymmetric gamma adjustment, based on the image residual distribution condition after the image residual processing of the display module to be adjusted, gamma vo
