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.
