Abstract
A pixel circuit includes a driving sub-circuit, a data writing sub-circuit, a compensation sub-circuit, a storage sub-circuit, and a first control sub-circuit. The data writing sub-circuit is configured to write a data signal provided by a data line into a second node under control of a first scan line. The compensation sub-circuit is configured to write a threshold voltage of the driving sub-circuit into the first node under control of a second scan line. A period of time for which the data writing sub-circuit writes the data signal into the second node is shorter than a period of time for which the compensation sub-circuit writes the threshold voltage of the driving sub-circuit into the first node.
