Abstract
The present disclosure provides a pixel driving circuit and a driving method thereof, a display panel, and a display device. The pixel driving circuit, comprising: a driving current generating circuit having a control terminal, a first terminal, and a second terminal; a data circuit configured to provide a signal from a data signal terminal to the control terminal of the driving current generating circuit in response to a signal from a first scan signal terminal, and provide a signal from the data signal terminal to the second terminal of the driving current generating circuit in response to a signal from a second scan signal terminal; a voltage circuit configured to provide a signal from a first voltage signal terminal to a first node in response to a signal from a light-emitting control signal terminal; and a control circuit configured to electrically connect the first node and the control terminal of the driving current generating circuit in response to a signal from the second scan signal terminal, and electrically connect the first node and the first terminal of the driving current generating circuit in response to a signal from a third scan signal terminal.
