Abstract
Disclosed are a display panel and a pixel circuit thereof. The pixel circuit includes a driving transistor, a data write-in circuit, a compensation circuit, a voltage control circuit, a light-emitting switch, and a light-emitting element. The driving transistor receives a power supply voltage. The data write-in circuit receives a first scanning signal, an emission signal, and a write-in data signal, stores the write-in data signal, and provides the write-in data signal to a control end of the driving transistor. The compensation circuit has a first switch and a second switch coupled to a relay end and controlled by a second scanning signal. The voltage control circuit adjusts a voltage difference between the control end of the driving transistor and the relay end. The light-emitting switch is coupled between a second end of the driving transistor and the light-emitting element, and is controlled by the emission signal.
