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 transistor in the threshold compensation module is a P-type transistor and a transistor in the light-emitting control module is an N-type transistor, or the transistor in the threshold compensation module is an N-type transistor and the transistor in the light-emitting control module is P-type transistor. 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.
