Abstract

A pixel circuit includes a driving unit, a light emitting unit having a second terminal receiving a second voltage, a compensation capacitor, and first, second and third switches. The first switch has a first terminal connected to the driving unit, and a control terminal for receiving a first control signal. The second switch has a first terminal coupled to the second terminal of the first switch, a second terminal for receiving an initialization signal, and a control terminal for receiving the first control signal. The compensation capacitor has a first terminal coupled to the second terminal of the first switch, and a second terminal coupled to the first terminal of the light emitting unit. The third switch has a first terminal connected to the driving unit, a second terminal coupled to the first terminal of the light emitting unit, and a control terminal for receiving a light emission control signal.
