Abstract:
1. A pixel comprising: a pixel driver formed near an intersection of a scan line and a data line, wherein the pixel driver is connected to a first power source voltage supply line, and comprises: an organic light emitting diode (OLED) configured to emit light according to the driving current; and an inverse voltage transistor positioned between an anode of the organic light emitting diode (OLED) and a reverse bias power source, the inverse voltage transistor including a gate electrode connected to one of a first electrode and a second electrode, and configured to transmit an inverse voltage to the organic light emitting diode (OLED) during a turn-off period of the driving transistor, wherein a channel width to length ratio of the inverse voltage transistor is less than a channel width to length ratio of the driving transistor.
