1. A display panel, comprising:
at least one pixel circuit, a pixel circuit of the at least one pixel circuit comprising a driving transistor and a third transistor; and
a light emitting element,
wherein the third transistor is configured to provide an adjusting voltage to the driving transistor, and wherein the third transistor comprises a first terminal connected to a voltage adjusting signal input terminal, a second terminal connected to the driving transistor, and a gate connected to a third control signal terminal;
wherein an operation process of the display panel comprises a reset and adjustment phase; and
during the reset and adjustment phase, the third transistor writes the adjusting voltage to a source of the driving transistor, a voltage of a gate of the driving transistor is Vg2, and a voltage of the source of the driving transistor is Vs2, where Vg2−Vs2≤−2V.
