Abstract
Display panel and driving method thereof, and display device are provided. The display panel includes sub-pixels. Each sub-pixel includes a pixel circuit and a light-emitting element. The pixel circuit includes a driving transistor, a data input module, a threshold compensation module, and a bias adjustment module. First electrode of the driving transistor is connected to the data input module and the bias adjusting module. First terminal of the data input module is connected to a data signal, a second terminal of the data input module is connected to the first electrode of the driving transistor. First terminal of the bias adjustment module is connected to a bias adjustment signal, a second terminal of the bias adjustment module is connected to the first electrode of the driving transistor. The threshold compensation module is connected between a gate of the driving transistor and a second electrode of the driving transistor.
