Pixel driving circuit, display panel and driving method thereof, and display device

A pixel driving circuit configured to drive a light-emitting element to emit light, the pixel driving circuit comprising:

• a driving sub-circuit electrically coupled to the light-emitting element and configured to generate a driving current for causing the light-emitting element to emit light, the driving sub-circuit having a threshold voltage;
• a light emission control sub-circuit electrically coupled to the driving sub-circuit and the light-emitting element, and configured to receive a light emission control signal and control the driving sub-circuit to output the driving current to the light-emitting element under control of the light emission control signal;
• and
• a data write sub-circuit electrically coupled to the driving sub-circuit and the light emission control sub-circuit, and electrically coupled with the driving sub-circuit at a first node and a second node, and configured to receive a scan signal and a data signal, and set a voltage of the first node to a voltage corresponding to the data signal, and set a voltage of the second node to the threshold voltage under control of the scan signal.
