Apparatus and method for driving organic light-emitting diode

1. A driving apparatus for an organic light-emitting diode, comprising:

an organic light-emitting diode;

a driving switch that drives the organic light-emitting diode in response to a control voltage applied to a gate terminal of the driving switch;

a high-level voltage source that supplies a high-level voltage to the driving switch;

a data driving circuit that supplies a data voltage to a data line of the driving apparatus;

a reference voltage source that supplies a reference voltage to the driving apparatus; and

a capacitor has a first electrode connected to the gate terminal of the driving switch via a first node, and a second electrode connected to a second node;

a first switch between the high-level voltage source and a drain of the driving switch and controlled by a first selection signal provided from a pre-stage scan line;

a second switch between a source of the driving switch and the organic light-emitting diode;

a third switch between the gate and the source of the driving switch and controlled by a second selection signal provided from a selection signal line;

a fourth switch between the data line and the second node of the capacitor and controlled by the second selection signal; and

a fifth switch between the second node and the reference voltage source and controlled by a third selection signal provided from a present-stage scan line, wherein the second selection signal and the third selection signal are in opposite phase with respect to each other, and the first selection signal is in opposite phase and delayed by one horizontal period with respect to the second selection signal.

2. The driving apparatus according to claim 1 , wherein each of the first to fifth switches includes one of a P-type switch and an N-type switch.
