1. A display panel comprising a pixel circuit and a light-emitting element, wherein
the pixel circuit comprises a driving circuit and a data writing circuit;
the driving circuit is configured to supply a driving current to the light-emitting element;
the data writing circuit is configured to write a data signal into the driving circuit; and
an operating mode of the display panel comprises a first mode and a second mode, wherein brightness of the display panel in the first mode is greater than brightness of the display panel in the second mode;
in the first mode, when the display panel displays a black state image, the data signal written into the driving circuit corresponding to the light-emitting element is black state voltage G01;
and in the second mode, when the display panel displays the black state image, the data signal written into the driving circuit corresponding to the light-emitting element is black state voltage G02, wherein G01≠G02,
wherein the driving circuit comprises a driving transistor; and
in a case where the driving transistor is a P-type transistor, G01<G02; or
in a case where the driving transistor is an N-type transistor, G01>G02.
