Abstract: The display substrate includes a plurality of pixel driving circuits correspondingly coupled to second light-emitting devices, respectively. The pixel driving circuit includes a first drive control circuit in the bezel area, and a second drive control circuit in the second display area. The first drive control circuit is coupled to the second drive control circuit through first wire, and the second drive control circuit is coupled to a corresponding second light-emitting device. Each first drive control circuit is configured to generate a drive current for driving the corresponding second light-emitting device. Each second drive control circuit is configured to make the path between the first drive control circuit and the corresponding second light-emitting device conducting after the path being non-conducting for a period of time, when the drive current moves between the second drive control circuit and the first wire.

Abstract: The present disclosure discloses a display panel and a display device. The display panel includes a base substrate including a first display region and a second display region. Since pixel circuits for driving light-emitting elements in the second display region are only disposed in the first display region but not disposed in the second display region, the light transmittance of the second display region is ensured to be good. Correspondingly, the display panel in the present disclosure has a good display effect.
