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 bias adjustment module. The drive module is configured to provide a drive current to the light-emitting element, and includes a drive transistor. The bias adjustment module is connected between a first terminal of the drive transistor and a bias signal terminal, a control terminal of the bias adjustment module is connected to a first scan signal terminal, and a second terminal of the drive transistor is coupled to the light-emitting element. A working process of the pixel circuit includes a pre-stage, the pre-stage includes a bias adjustment stage, the bias adjustment module is turned on in the bias adjustment stage, and the bias signal terminal provides a bias signal to the first terminal of the drive transistor.
