Abstract
Provided is a pixel driving circuit, including: a reset sub-circuit configured to reset a voltage of a first node based on a first scanning signal, and reset a voltage of a second node based on a second scanning signal; a data writing sub-circuit configured to write a data signal into the second node; a driving transistor configured to generate a driving current based on the voltage of the second node; a first emission control sub-circuit configured to transmit a first power supply signal to the driving transistor; a second emission control sub-circuit configured to transmit the driving current to the anode; a storage sub-circuit configured to store the voltage of the second node and adjust the voltage of the first node; an anode reset sub-circuit configured to reset the anode; the first scanning signal line, the third scanning signal line and the fourth scanning signal line are different gate lines.
