Abstract
Provided display panel includes: a pixel circuit and a light-emitting element. The pixel circuit includes a dimming module, a drive module providing drive current for the light-emitting element and including a drive transistor, and a bias module connected between bias signal terminal and first terminal of the drive transistor and configured to perform bias adjustment on the drive transistor. A control terminal of the bias module is connected to bias control terminal, and the bias signal terminal is provided with bias signal. The pixel circuit includes working stages including at least a first and a second working stage and a second working stage, a light emission duration of the light-emitting element in the first working stage is different from that in the second working stage, and a bias signal voltage provided by the bias signal terminal in the first working stage is different from that in the second working stage.
