Abstract: A pixel circuit includes a data writing sub-circuit, a driving sub-circuit, and one or more potential maintenance sub-circuits. The data writing sub-circuit is coupled to at least a first voltage signal terminal, a data signal terminal, a first scan signal terminal and a first node, and writes a data signal provided by the data signal terminal into the first node under control of at least a first scan signal provided by the first scan signal terminal. The driving sub-circuit is coupled to the first node, a second node and a third node, and creates a path between the second node and the third node under control of a potential at the first node. A potential maintenance sub-circuit is coupled to a circuit node and a reference signal terminal, and maintains a potential at the circuit node through a reference signal provided by the reference signal terminal.
