Provided display panel includes pixel circuit and light emitting element. The pixel circuit includes drive module including a drive transistor, bias adjustment module to provide a bias adjustment signal to a first pole or a second pole of the drive transistor and initialization module to provide initialization signal to the light emitting element. Operation modes include a first mode and a second mode, and brightness level of the display panel in the first mode greater than that in the second mode. The pixel circuit includes data writing frame and holding frame, data writing frame in first mode corresponds to initialization signal of Vi11, holding frame in first mode corresponds to initialization signal of Vi12, data writing frame in second mode corresponds to bias adjustment signal of Vs21, holding frame in second mode corresponds to bias adjustment signal of Vs22, and |Vi11−Vi12|≠|Vs21−Vs22|.
