Abstract: 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.

Abstract: The present disclosure provides a light-emitting element, a light-emission compensation method and an electronic device. The light-emitting element includes a substrate and at least one light-emitting unit arranged on the substrate.
