Claim 9:
10. A display panel, comprising:
at least one pixel circuit; and
a light emitting element,
wherein one pixel circuit of the at least one pixel circuit comprises a driving transistor, a second transistor, and a third transistor, wherein the second transistor is configured to provide a data signal to a source of the driving transistor, and the third transistor is configured to provide an adjusting voltage to the source of the driving transistor;
wherein an operation process of the display panel comprises a data writing phase and a reset and adjustment phase;
wherein during the data writing phase, the second transistor is turned on, the data signal is VData, a data line is configured to provide the data signal to the source of the driving transistor, a gate of the driving transistor is configured to receive the data signal, and a voltage of the gate of the driving transistor is VData+Vth, where Vth denotes a threshold voltage of the driving transistor;
wherein, during the reset and adjustment phase, the third transistor is turned on, a voltage adjusting signal line is configured to provide the adjusting voltage to the source of the driving transistor, the adjusting voltage is VJ, a voltage of the source of the driving transistor is VJ, and the voltage of the gate of the driving transistor remains VData+Vth; and
wherein VData+Vth−VJ≤−2V.
