Display device and method of driving the same

A method of driving a display device including a light-emitting element, a capacitor connected between first and second contact points, and a driving transistor that has a control terminal connected to the second contact point, an input terminal connected to a driving voltage, and an output terminal connected to the light-emitting element, the method comprising:

• connecting the control terminal to the output terminal of the driving transistor and connecting the output terminal of the driving transistor to a reference current source;
• connecting the first contact point to a sustain voltage;
• and
• disconnecting the connection between the control terminal and the output terminal of the driving transistor, disconnecting the connection between the output terminal of the driving transistor and the reference current source, disconnecting the connection between the first contact point and the sustain voltage, and connecting the first contact point to a data voltage.
