A display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a driving module, and the driving module includes a driving transistor. A time period of one frame of the display panel includes a non-light-emitting stage and a light-emitting stage, and the non-light-emitting stage includes a bias adjustment stage, in which one of a source and a drain of the driving transistor receives a bias adjustment signal. An operating state of the pixel circuit includes a first mode and a second mode, a time length of the non-light-emitting stage in the first mode is L1, and a time length of the non-light-emitting stage in the second mode is L2, where L1>L2. A working process of the display panel in the first mode includes a first frame, and a working process of the display panel in the second mode includes a second frame.
