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.
