Abstract:
A display panel, a display device, a pixel driving circuit, and a control method for the pixel driving circuit. The pixel driving circuit includes a data writing module for transmitting signal of the data signal end to the first node in response to enable signal of the first control signal end; a coupling writing module for transmitting signal of the first power source voltage end to the first node in response to enable signal of the second control signal end; a storage capacitor; a driving transistor; a first switch unit; a second switch unit; a reset module for transmitting signal of the reset signal line to the fourth node in response to enable signal of the fifth control signal end; and a light emitting element, an anode thereof being electrically connected to the fourth node, an cathode thereof being electrically connected to a second power source voltage end.

Claim (Index 15):
The control method for a pixel driving circuit according to  claim 14 , wherein the pixel driving circuit further comprises a sixth switch transistor, the first end of the driving transistor is electrically connected to the first power source voltage end by the sixth switch transistor, a first end of the sixth switch transistor is electrically connected to the first power source voltage end, a second end of the sixth switch transistor is electrically connected to the first end of the driving transistor, and a control end of the sixth switch transistor is electrically connected to a sixth control signal end;\n wherein the control method comprises: providing a non-enable signal to the first control signal end and the sixth control signal end, and providing an enable signal to the second control signal end, the third control signal end, the fourth control signal end and the fifth control signal end in the first stage, so that the signal of the first power source voltage end is transmitted to the first node and the signal of the reset signal line is transmitted to the fourth node, the third node and the second node; providing a non-enable signal to the second control signal end and the fourth control signal end, and providing an enable signal to the first control signal end, the third control signal end, the fifth control signal end and the sixth control signal end in the second stage, so that the signal of the data signal end is transmitted to the first node, a threshold compensation is performed to the second node by the first power source voltage end, and the signal of the reset signal line is transmitted to the fourth node; and providing a non-enable signal to the first control signal end, the third control signal end and the fifth control signal end, and providing an enable signal to the second control signal end, the fourth control signal end and the sixth control signal end in the third stage, so that the signal of the first power source voltage end is transmitted to the first node and a conduction path between the first power source voltage end and the second power source voltage end is formed.
