PIXEL, DISPLAY DEVICE INCLUDING THE SAME AND DRIVING METHOD THEREOF
Abstract:
A display device comprising a plurality of pixels is disclosed. In one aspect, each pixel of the display device comprises a first capacitor connected between a data line and a first node, a reference voltage transistor configured to apply a reference voltage on the first node, a driving transistor having a gate connected to a second node and configured to control a drive current flowing from a first power supply voltage to an organic light emitting diode in response to a voltage of the second node applied to the gate of the driving transistor, a light emitting transistor configured to apply the first power supply voltage to an electrode of the driving transistor in response to a light emission signal applied to a gate of the light emitting transistor, a second capacitor connected between the second node and an anode of the organic light emitting diode, and a relay transistor configured to electrically connect the first node and the second node in response to a write signal applied to a gate of the relay transistor.
