Patent ID: 7724218

Claim:
An organic light-emitting diode display device, comprising: a driving voltage source; a reference voltage source that generates a reference voltage; a reference current source; a storage capacitor connected between a first node and a second node; an organic light-emitting diode device connected between a third node and a ground voltage source; a first scanning signal that is supplied to a first scan line; a second scanning signal that is supplied to a second scan line, the second scanning signal having an inverse-phase against the first scanning signal; a data line that crosses the first and second scan lines, and to which a data voltage is supplied; a first switch element that is operative to supply a reference voltage to the first node; a second switch element that is operative to supply the data voltage to the first node; a third switch element that is operative to adjust a current which is supplied to the organic light-emitting diode device in accordance with a voltage of the second node; a fourth switch element that is operative to supply the reference current to the second node; a fifth switch element that is operative to form a current path between the second node and the third node; and a sixth switch element that is operative to cut-off a current that flows into the organic light-emitting diode device via the third node and forms a current path between the third node and the organic light-emitting diode device.
