Claim 19:
20. A method of driving a display device including a plurality of pixels,
at least one of the pixels, which is connected to an i-th horizontal line, where i is a natural number, including:
a first transistor connected between a first power source and a fourth node, and having a gate electrode connected to a first node;
a second transistor connected between a third node and a data line, and turned on in response to a scan signal applied to an i-th first scan line, where i is natural number;
a third transistor connected between the first node and the fourth node, and turned on in response to a scan signal applied to an i-th third scan line, where i is integer natural number;
a fourth transistor connected between a second node and an initialization voltage, and turned on in response to a scan signal applied to an i-th second scan line, where i is integer natural number;
an organic light emitting diode connected between the second node and a second power source;
a first capacitor connected between the third node and the first node; and
a second capacitor connected between the first node to which the gate electrode of the first transistor is connected and the second node to which an anode of the organic light emitting diode is connected, the method comprising:
turning on the second transistor and the third transistor during a first period; and
turning on the fourth transistor during a second period subsequent to the first period.
