Abstract

A pixel circuit of a display panel includes a light emitting device, a driving transistor, a capacitor, a first reset transistor and a second reset transistor. The driving transistor has a gate terminal. A first terminal of the capacitor is coupled to the gate terminal of the driving transistor, and a second terminal of the capacitor is coupled to a reset input terminal of the pixel circuit. A first terminal of the first reset transistor is coupled to the gate terminal of the driving transistor, and a second terminal of the first reset transistor is coupled to the reset input terminal. A first terminal of the second reset transistor is coupled to the light emitting device, and a second terminal of the second reset transistor is coupled to the reset input terminal.
