Abstract: A pixel circuit includes three transistors, a capacitor, and an OLED. The first transistor includes a gate terminal for receiving a first control signal, a first terminal connected to a first node, and a second terminal connected to a second node. The second transistor includes a gate terminal for receiving a second control signal, a first terminal connected to the second node, and a second terminal connected to a third node. The third transistor includes a gate terminal connected to the first node, a first terminal for receiving a first power signal, and a second terminal connected to the third node. The capacitor may receive an initialization signal and is connected to the first node. The OLED is connected to the third node and may receive a second power signal. The control signals have same voltage levels in a data writing period and have different voltage levels in other periods.
