Claim 9:
10. A display panel comprising:
a display area and a non-display area surrounding the display area, wherein the display panel comprises a gate driving circuit disposed in the non-display area and a pixel driving circuit disposed in the display area, the gate driving circuit being connected to the pixel driving circuit, and the gate driving circuit being configured for providing a scan signal to the pixel driving circuit;
wherein pixel driving circuit comprises:
a driving transistor, a first terminal of the driving transistor being connected to a power source, a second terminal of the driving transistor being connected to a light emitting unit;
a storage capacitor, a first terminal of the storage capacitor being connected to a control terminal of the driving transistor, and a second terminal of the storage capacitor being connected to the power source;
a first response switch, provided with a first terminal connected to a data line, a control terminal connected to a scan line, and a second terminal connected to the first terminal of the storage capacitor, the control terminal of the first response switch being configured to respond to a scan signal provided by the scan line to provide a data signal provided by the data line to the first terminal of the storage capacitor;
a trigger with an input terminal connected to the scan line, and the trigger generating a first control signal in response to the scan signal of the scan line; and
a second response switch with a first terminal connected to the second terminal of the driving transistor, a second terminal connected to an initial voltage terminal, a control terminal connected to an output terminal of the trigger, wherein the control terminal of the second response switch provides a voltage of the initial voltage terminal to the second terminal of the driving transistor in response to the first control signal;

wherein the input terminal of the trigger comprises a first input terminal and a second input terminal, and the first input terminal and the second input terminal being connected to the scan line; and
wherein the pixel driving circuit further comprises an inverter, one terminal of the inverter being connected to the second input terminal, and another terminal of the inverter being connected to the scan line.
