Provided display panel includes pixel circuit and light emitting element. The pixel circuit includes a drive module including a drive transistor, and an initialization module to provide an initialization signal to the light emitting element. Operation modes of the display panel include a first mode and a second mode, and a brightness level of the display panel in the first mode is greater than a brightness level of the display panel in the second mode. An operation process of the pixel circuit includes a data writing frame and a holding frame; the data writing frame and the holding frame in the first mode respectively correspond to an initialization signal of Vi11 and Vi12; the data writing frame and the holding frame in the second mode respectively correspond to an initialization signal of Vi21 and Vi22; where |Vi11−Vi12|≠|Vi21−Vi22|.
