Abstract
Provided are a display panel and a display device. The display panel includes a light-emitting element and a pixel drive circuit electrically connected to the light-emitting element. The pixel drive circuit includes a drive transistor and a first reset module. The drive transistor is configured to control a drive current. The first reset module is connected to a first node and configured to provide a first reset voltage to the first node. The light-emitting element is connected to the first node. A working mode of the display panel comprise a first drive mode. A display frame in the first drive mode includes a valid frame and an invalid frame. In the first drive mode, a first reset voltage for the valid frame is different from a first reset voltage for the invalid frame.
