The present disclosure provides a pulse width modulation method, a pulse width modulation module and a display device. A display panel includes a pixel circuitry configured to receive a light-emission control signal and control a light-emitting element to emit light under the control of the light-emission control signal, and a display period includes a refresh frame and a maintenance frame. The pulse width modulation method includes: increasing at least one active pulse width of the light-emission control signal within the refresh frame so that the at least one active pulse width of the light-emission control signal is larger than a first active pulse width threshold; and/or decreasing at least one active pulse width of the light-emission control signal within the maintenance frame so that the at least one active pulse width of the light-emission control signal is less than a second active pulse width threshold.

Pulse width modulation method, pulse width modulation module, and display device

A method for adjusting a gamma voltage of a display module is provided. The method includes: 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.
