Abstract
Provided are a display panel, a driving method, and a display device. The display panel includes: a gate driving circuit, a pixel driving circuit, and a light-emitting component. The pixel driving circuit includes a driving transistor, a data writing module, a threshold compensation module, and a light-emitting control module. A control terminal of the threshold compensation module and a control terminal of the light-emitting control module are electrically connected to a same gate driving circuit. The light-emitting control module includes a first light-emitting control unit and a second light-emitting control unit. The pixel driving circuit further comprises a blocking module which is electrically connected between the first power signal terminal and the first terminal of the driving transistor, and is connected in series to the first light-emitting control unit.
