A method for adjusting a gamma voltage of a display module. The method comprises: obtaining a gamma voltage of a display module at a basic refresh frequency; obtaining an association 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 on the basis of the gamma voltage of the display module at the basic refresh frequency and the association relationship. By means of the adjustment method, different gamma voltages are used according to different refresh frequencies, such that the multi-frequency switching effect of different gray scales under the same display brightness value during a frequency switching process can be effectively improved without occupying a relatively large storage space of an integrated circuit chip and without increasing the time for gamma tuning.
