1. A display panel, comprising:
at least one pixel circuit each comprising a data writing module and a driving module; and
a light emitting element,
wherein the data writing module is configured to provide a data signal and an adjusting voltage, and the driving module comprises a driving transistor;
an operation process of the display panel comprises a data writing phase and a reset and adjustment phase;
during the data writing phase, the data writing module is turned on and configured to write the data signal;
during the reset and adjustment phase, the data writing module is turned on and configured to write the adjusting voltage; and
during the reset and adjustment phase, a voltage of a gate of the driving transistor is Vg2, and a voltage of a source of the driving transistor is Vs2, where Vg2−Vs2<−2V.
