1. A method for adjusting a gamma voltage of a display module, comprising:
obtaining a gamma voltage of the display module at a basic refresh frequency;
obtaining an associated relationship between the gamma voltage of the display module at the basic refresh frequency and a gamma voltage of the display module at a target refresh frequency; and
determining the gamma voltage of the display module at the target refresh frequency based on the gamma voltage of the display module at the basic refresh frequency and the associated relationship,
wherein the associated relationship corresponds to a display brightness value of the display module, and different display brightness values correspond to respective associated relationships;
the method for adjusting the gamma voltage of the display module further comprises:
determining a current display brightness value of the display module,
wherein obtaining the gamma voltage of the display module at the basic refresh frequency comprises:
obtaining, at the current display brightness value, the gamma voltage of the display module at the basic refresh frequency; and
wherein obtaining the associated relationship between the gamma voltage of the display module at the basic refresh frequency and the gamma voltage of the display module at the target refresh frequency comprises:
obtaining, at the current display brightness value, the associated relationship between the gamma voltage of the display module at the basic refresh frequency and the gamma voltage of the display module at the target refresh frequency.
