PIXEL CIRCUIT

A pixel circuit is provided. In the pixel circuit, a first transistor has a first terminal coupled to a first node and a second terminal receiving a system high voltage, and the first transistor is controlled by a light emitting signal. A first terminal and a second terminal of a second transistor are respectively coupled to a second node and the first node; a control terminal of the second transistor is coupled to a third node. The third transistor is coupled between the first node and the third node and controlled by a first scan signal. A capacitor has a first terminal and a second terminal. A voltage setting circuit receives a data signal, a second scan signal, and a third scan signal. A first terminal of the light emitting device is coupled to the second node; a second terminal of the light emitting device receives a system low voltage.
