Abstract: Provided are a display panel and a display device. The display panel includes at least two display regions and a pixel circuit. The at least two display regions include a first display region and a second display region. The pixel circuit includes at least a first pixel circuit and a second pixel circuit, where the first pixel circuit is disposed in the first display region and the second pixel circuit is disposed in the second display region. The pixel circuit receives a bias adjustment signal including a first bias adjustment signal and a second bias adjustment signal, where when a refresh rate of the first display region is f1, the first pixel circuit receives the first bias adjustment signal, and when a refresh rate of the second display region is f2, the second pixel circuit receives the second bias adjustment signal.

Abstract: Provided are a driving method for a display panel, and a display device. The display panel includes multiple pixels arranged in an array and multiple data lines, pixels located in the same column are electrically connected to the same data line, and the multiple data lines are configured to provide data signals for the multiple pixels in stages. The driving method includes acquiring a voltage difference between data signals provided for each data line in two adjacent stages; determining a charge current of each data line according to the voltage difference; and providing the data signal for each data line with the charge current.

Abstract: Provided are a display panel and a display device. The display panel includes at least two display regions and a pixel circuit. The at least two display regions include a first display region and a second display region. The pixel circuit includes at least a first pixel circuit and a second pixel circuit, where the first pixel circuit is disposed in the first display region and the second pixel circuit is disposed in the second display region. The pixel circuit receives a reset signal including a first reset signal and a second reset signal, where when a refresh rate of the first display region is f1, the first pixel circuit receives the first reset signal, and when a refresh rate of the second display region is f2, the second pixel circuit receives the second reset signal.
