Abstract
A driving apparatus for an organic light-emitting diode includes 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 that applies the control voltage to the gate terminal of the driving switch, the control voltage being a difference between the data voltage and the reference voltage.
