Abstract
A pixel circuit includes a light-emitting element, a capacitor structure, a driving transistor, and first to fourth switching elements. The first switching element connects a data line for providing a data signal to a first terminal of the capacitor structure in response to a first scan signal. The second switching element connects a first terminal of the driving transistor to a control terminal of the driving transistor and a second terminal of the capacitor structure respectively in response to a second scan signal. The third switching element connects a second terminal of the driving transistor to a first terminal of the light-emitting element in response to a third scan signal. The fourth switching element connects a first power signal terminal to the first terminal of the driving transistor in response to a fourth scan signal.
