ABSTRACT:
A pixel including a light-emitting element, a driving transistor, a maintain capacitor, a switch device, and a control device. The driving transistor is serially coupled to the light-emitting element for driving the light-emitting element to emit light and has a threshold voltage and a gate connected to a point. A first terminal of the maintain capacitor is connected to the point. The switch device is controlled by a scan signal and connected between a data line and the point. The control device is connected to a second terminal of the maintain capacitor. When the switch device is turned off, the control device provides a first control voltage, the value of which is determined by the threshold voltage, to the point through the maintain capacitor.
