Abstract
A pixel driving circuit and a driving method therefor, and a display substrate. The pixel driving circuit comprises: an isolation sub-circuit, configured to connect or disconnect a third node (N3) and a fifth node (N5) under the control of a signal of a second scanning signal end (Gate2), and store the signals of a first node (N1) and the fifth node (N5); a first control sub-circuit, configured to provide a signal of a data signal end (Data) to the first node (N1) under the control of a signal of a first scanning signal end (Gate1); and second control sub-circuits, configured to separately provide a signal of at least one initial signal end (INIT1, INIT2, INIT3) to one node among a second node (N2), a fourth node (N4), the third node (N3), and the fifth node (N5) under the control of a signal of at least one reset signal end (Reset1, Reset2, Reset3).
