1. A display panel, comprising:
a pixel circuit and a light emitting element;
wherein the pixel circuit comprises a drive module, a bias adjustment module and an initialization module;
wherein the drive module comprises a drive transistor;
the bias adjustment module is configured to provide a bias adjustment signal to a first pole of the drive transistor or a second pole of the drive transistor; and
the initialization module is configured to provide an initialization signal to the light emitting element;
wherein operation modes of the display panel comprise 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; and
wherein an operation process of the pixel circuit comprises a data writing frame and a holding frame;
the data writing frame in the first mode corresponds to an initialization signal of Vi11, and the holding frame in the first mode corresponds to an initialization signal of Vi12;
the data writing frame in the second mode corresponds to a bias adjustment signal of Vs21, and the holding frame in the second mode corresponds to a bias adjustment signal of Vs22; and
|Vi11−Vi12|≠|Vs21−Vs22|.
