Patent ID: 10565932

Abstract:
A pixel circuit includes a driving sub-circuit, a compensation sub-circuit, a data writing sub-circuit, and a data voltage storage sub-circuit. The driving sub-circuit includes a first electrode electrically coupled to a high voltage input terminal and a second electrode configured to output a driving current. The compensation sub-circuit is configured to store a threshold voltage of the driving sub-circuit. The compensation sub-circuit includes a first terminal electrically coupled to the second electrode of the driving sub-circuit, a second terminal electrically coupled to a gate electrode of the driving sub-circuit, a third terminal, and a fourth terminal, and a control terminal. The data writing sub-circuit includes a first terminal and a second terminal. The data voltage storage sub-circuit includes a first terminal electrically coupled to the third terminal of the compensation sub-circuit and the second terminal of the data writing sub-circuit; and a second terminal.
