Abstract
A pixel circuit, a display panel and a display device. The pixel circuit includes drive transistor, storage capacitor, compensation circuit, and voltage controller. The drive transistor has a gate electrode connected to a first node and generates a drive current in a light-emitting phase of an operation cycle of the pixel circuit. The storage capacitor has a first plate connected to the first node and a second plate connected to a second node and stores a data voltage inputted to the gate electrode of the drive transistor. The compensation circuit has an output terminal connected to the second node and a first input terminal receiving a first power supply voltage and compensates a deviation of the first power supply voltage affecting the drive current. The voltage controller is connected to the second node and controls a fluctuation of a voltage of the second node prior to the light-emitting phase.
