Abstract
A pixel circuit and a driving method thereof, a display substrate and a display device are provided. The pixel circuit includes a driving sub-circuit, a first switch sub-circuit and a first light-emitting control sub-circuit. The driving sub-circuit includes a control terminal connected with a first node, a first terminal connected with a second node and a second terminal connected with a third node, and is configured to control a driving signal from the first node to the third node for driving a light-emitting element; the first switch sub-circuit is configured to control conduction of the driving signal between the third node and a fourth node; the first light-emitting control sub-circuit is connected with a first electrode of the light-emitting element through a fifth node, and is configured to control conduction of the driving signal between the fourth node and the fifth node.
