Abstract
A pixel circuit and a driving method thereof, a display substrate, and a display panel are provided. The pixel circuit includes: a data writing sub-circuit configured to write a data voltage into a storage sub-circuit; the storage sub-circuit configured to store the data voltage; a driving sub-circuit electrically connected to a first node and configured to drive a light-emitting component electrically connected to a second node to emit light according to the data voltage; a light-emitting control sub-circuit electrically connected to the first node and the second node, respectively, and configured to achieve to turn on or turn off connection between the driving sub-circuit and the light-emitting component; and a first compensation sub-circuit electrically connected to the first node and the second node, respectively, and configured to compensate a level of the second node according to a level of the first node.
