Organic light-emitting diode display device and driving method thereof

A method of driving an organic light-emitting diode display device having a data line, first and second gate lines crossing the data line, an emission line crossing the data line, an organic light-emitting diode device having an anode electrode and a cathode electrode, a first switch element, a second switch element, a third switch element, a driving element, a first capacitor and a second capacitor, comprising:

• supplying a high-level potential driving voltage to the anode electrode from a high-level potential driving voltage source;
• connecting a cathode electrode of the organic light-emitting diode device to a first node through the first switch element in response to a first scanning pulse from the first gate line;
• connecting the data line to a second node through the second switch element in response to a second scanning pulse from the second gate line;
• connecting the second node to a ground voltage source through the third switch element in response to an emission pulse from the emission line;
• adjusting a current flowing between the cathode electrode of the organic light-emitting diode device and the second node through the driving element in accordance with a voltage on the first node;
• and
• emitting light from the organic light-emitting diode device,
• wherein the first and second scanning pulses are at an active logic voltage during a first period, and the first and second scanning pulses are maintained at the active logic voltage during a second period.
