Abstract
A pixel driving circuit, a driving method therefor, and a display device. The pixel driving circuit comprises: a driving sub-circuit, a first control sub-circuit, and a second control sub-circuit. The first control sub-circuit is separately electrically connected to a first scanning signal end, a second scanning signal end, a data signal end, a first signal end, a second signal end, a first node, and a third node, and is configured to provide a signal to the first node under the control of signals of the first scanning signal end, the second scanning signal end, the data signal end, the first signal end, the second signal end, and the third node. The second control sub-circuit is separately electrically connected to a first light-emitting signal end, a first power supply end, and a second node, and is configured to provide a signal of the first power supply end to the second node under the control of a signal of the first light-emitting signal end. The driving sub-circuit is separately electrically connected to the first node, the second node, and the third node, and is configured to provide a driving current to the third node under the control of signals of the first node and the second node.
