Abstract: A pixel includes a display element, a driving transistor, a storage capacitor, a scan transistor, and a gate control circuit. The display element may emit light for an emission period, wherein the display element includes an anode and a cathode. The driving transistor may control an amount of a driving current flowing through the display element, wherein the driving transistor includes a first gate and a second gate. The storage capacitor is electrically connected to the first gate of the driving transistor. The scan transistor may be turned on for a data-write period for transferring a data voltage to the driving transistor. The lower gate control circuit may electrically connect the second gate of the driving transistor to the anode of the display element for the emission period, and may apply a bias voltage to the second gate of the driving transistor for the data-write period.
