Abstract
A pixel circuit is provided. The pixel circuit includes: a light-emitting element, a driving circuit, a capacitor, a first compensation circuit, a second compensation circuit, a reset read circuit, a data writing circuit, and a light-emitting control circuit. The light-emitting element has a cathode that receives a system low voltage. The driving circuit provides a driving current based on a gate voltage. The capacitor is coupled between a gate control node and a control node. The first compensation circuit provides a system high voltage to the control node and the driving circuit. The second compensation circuit provides a reference voltage to the driving circuit. The reset read circuit provides an initial voltage to the control node and the gate control node. The data writing circuit provides a data signal to the gate control node. The light-emitting control circuit provides the driving current to the light-emitting element.
