Abstract
The disclosure provides a pixel and a method of aging the pixel for reducing or preventing damage to a display element during aging of a driving transistor, the pixel including a display element including an anode and a cathode, a first transistor configured to control a magnitude of a driving current flowing to the display element in response to a gate-source voltage, the first transistor including a first gate electrode configured to function as a gate of the first transistor, a semiconductor layer, and a second gate electrode in a floating state between the first gate electrode and the semiconductor layer, and a second transistor configured to deliver a first voltage to the first transistor in response to a first scan signal.
