摘要： A display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a data-writing module, a driving module, and a compensation module. The driving module is configured to provide a driving current for the light-emitting element, wherein the driving module includes a driving transistor, and the driving transistor is an NMOS transistor. The data-writing module is configured to selectively provide a data signal for the driving module. The compensation module is configured to compensate a threshold voltage of the driving transistor. An operational process of the pixel circuit includes a bias stage. In the bias stage, the compensation module is turned off, the driving transistor receives a bias signal, and the bias signal is configured to adjust a bias state of the driving transistor.

摘要： A display panel, a driving method, and a display device are provided. The display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a data-writing module, a driving module, a compensation module, and a first light-emission controller. The driving module is configured to provide driving current for the light-emitting element. The driving module includes a driving transistor, and the driving transistor is an NMOS transistor. The data-writing module is connected between a data-signal input terminal and a first terminal of the driving transistor for selectively providing a data signal for the driving module. The compensation module is configured to compensate a threshold voltage of the driving transistor. The first light-emission controller is connected between a first power signal terminal and a second terminal of the driving transistor for selectively providing a first power signal to the driving module.
