| description | The invention provides a pixel circuit and a driving method thereof. The pixel circuit includes a light emitting unit, a first transistor, a second transistor, a third transistor, a first capacitor, asecond capacitor, and a switch. The first transistor is coupled between a first voltage source and a light emitting unit, and the gate of the first transistor is coupled to a first node. The first transistor is configured to provide a light-emitting unit supply voltage. The second transistor is coupled between the second voltage source and the first node, and the gate of the second transistor isconfigured to receive the first driving signal. One end of the third transistor is configured to receive a pixel signal, the other end of the third transistor is coupled to a second node, and the gateof the third transistor is configured to receive the first driving signal. The first capacitor is coupled between the first node and the light-emitting unit. The second capacitor is coupled between the second node and a third |
