Abstract:
1. An organic light-emitting diode display device, comprising: a driving voltage source providing a driving voltage; a ground voltage source providing a ground voltage; a first scan line receiving a first scanning signal; a second scan line receiving a second scanning signal; a data line crossing the first and second scan lines; a first switch element turned-on in response to the first scanning signal during a first period to supply a data from the data line to a first node, and then maintaining an off-state during a second period; a driving device adjusting a current through an organic light-emitting diode element in accordance with a voltage of the first node; a reference voltage source providing a reference voltage that is capable of turning-off the driving device; a second switch element maintaining an off-state during the first period, and turned-on during the second period to supply the reference voltage to the first node; and a storage capacitor maintaining the voltage at the first node.
