Abstract
Provided display panel includes at least one pixel circuit and at least one light-emitting element. The at least one pixel circuit is configured to drive the at least one light-emitting element to emit light. The at least one pixel circuit includes a drive module and a light emission control module. The drive module is configured to generate a drive current. The light emission control module is configured to control the drive current to be transmitted to a light-emitting element in response to a light emission control signal. A display period of the display panel includes a first display stage and a second display stage, where in the first display stage, an ineffective pulse duration for the light emission control signal is T1, in the second display stage, an ineffective pulse duration for the light emission control signal is T2, and T1>T2.
