Abstract:
A display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a driving module. The driving module includes a driving transistor, and is configured to provide a driving current for the light-emitting element. The pixel circuit includes a control terminal configured to receive a first light-emitting control signal, the first light-emitting control signal is an effective pulse, and the driving module corresponding to the control terminal is turned on during the effective pulse. A time period of one frame of the display panel includes a non-light-emitting stage and a light-emitting stage, 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.
