The present disclosure provides a pixel driving circuit, including: a storage sub-circuit (C1) configured to storage a data voltage and including a first terminal and a second terminal, which act as a first node (N1) and a second node (N2) of the pixel driving circuit respectively; a driving sub-circuit (T3) electrically connected to the second node (N2) and a third node (N3) of the pixel driving circuit and configured to provide a first power supply signal (ELVDD) to the third node (N3) under control of a potential at the second node (N2) to generate a driving current; an input sub-circuit electrically connected to the first node (N1) and configured to provide a data signal (Data) to the first node (N1) under control of a scanning signal (Gate), where the input sub-circuit includes a fourth transistor (T4) having a gate configured to receive the scanning signal (Gate), a first electrode configured to receive the data signal (Data), and a second electrode electrically connected to the first node (N1); a compensation sub-circuit (T2) electrically connected to the second node (N2) and the third node (N3) and configured to electrically connect the second node (N2) to the third node (N3) under control of the scanning signal (Gate); and a first light emission control sub-circuit (T6) electrically connected to the third node (N3) and configured to provide the driving current to a light-emitting element under control of a light emission signal (EM).
