Summary:A pixel circuit includes a light emitting element, a driving transistor, a capacitor, a write circuit, a first transistor and a second transistor. The light-emitting element is coupled to a first system voltage source. The driving transistor is coupled to the first node, the second node and a second system voltage source. The capacitor and the write circuit are coupled to the second node and the third node. The write-in circuit respectively writes data voltage and initial voltage to two ends of the capacitor according to the control signal. The first transistor is coupled between the driving transistor and the light-emitting element and is turned on in response to the driving signal. The second transistor is coupled to the first node and the third node and is switched on in response to the driving signal to change the data voltage and the initial voltage at the two ends of the capacitor so as to switch on the driving transistor, so that a driving current is generated between the first system voltage source an
