Pixel driving circuit and driving method thereof, display device

A pixel driving circuit, comprising:

• a reset sub-circuit coupled to a control signal terminal, a reference signal terminal and a first node, wherein the reset sub-circuit is configured to be turned on in response to a control signal received at the control signal terminal, and transmit a reference voltage received at the reference signal terminal to the first node to reset a voltage of the first node;
• an input sub-circuit coupled to a gate scan signal terminal, a data signal terminal and a second node, wherein the input sub-circuit is configured to transmit a data signal received at the data signal terminal to the second node in response to a gate scan signal received at the gate scan signal terminal;
• a driving sub-circuit coupled to the first node, the second node and a third node, wherein the driving sub-circuit is configured to be turned on or off in response to a voltage of the first node;
• and to write the data signal and a compensation signal into the third node;
• a compensation sub-circuit coupled to the gate scan signal terminal, the third node and a fourth node, wherein the compensation sub-circuit is configured to transmit the data signal and the compensation signal to the fourth node in response to the gate scan signal;
• and
• a voltage control sub-circuit coupled to the first node and the fourth node, wherein the voltage control sub-circuit is configured to control the voltage of the first node according to a voltage of the fourth node, and the driving sub-circuit is further configured to output a driving signal according to the voltage of the first node.
