Abstract
A pixel circuit includes an energy storage element, a driving transistor, a first transistor and a second transistor. The driving transistor has a gate electrically connected with the energy storage element. The first transistor has a first terminal electrically connected with the energy storage element and the gate of the driving transistor, and a second terminal electrically connected with the first terminal of the driving transistor. The second transistor has a first terminal electrically connected with the first terminal of the driving transistor and the second terminal of the first transistor, and a second terminal connected with a data voltage or a first voltage. During a first stage, the gates of the first and second transistors receive a first signal and a second signal, respectively, and the data voltage or the first voltage charges the energy storage element via the first and second transistors.
