Abstract
Provided are a display panel and a display device. The display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a drive module and a first initialization module. The drive module is configured to generate a drive current. The first initialization module is configured to supply a first initialization voltage to a first node. The first node is connected to the light-emitting element. A first control terminal of the first initialization module is configured to transmit the first initialization voltage to the first node in response to a first scan control signal. A display period of the display panel includes a first display stage and a second display stage. In the first display stage, a total effective-pulse duration of the first scan control signal is T. In the second display stage, the total effective-pulse duration of the first scan control signal is T. T<T
