Patent ID: 8044889

Claim:
A plasma display device comprising: a plasma display panel (PDP) and drivers for supplying driving signals to the PDP, wherein the driver comprises: a capacitor; a first switch connected to a first end of the capacitor and turned on in order to supply a voltage of the first end of the capacitor to the PDP; a second switch connected to a second end of the capacitor and turned on in order to supply a voltage of the second end of the capacitor to the PDP; a first voltage supplier connected to the first end of the capacitor to supply one of a sustain voltage and a reference voltage to the first end of the capacitor; and a second voltage supplier connected to the second end of the capacitor to supply the reference voltage to the second end of the capacitor, wherein a voltage difference between the both ends of the capacitor is sustained as the sustain voltage, and wherein the first voltage supplier comprises: a third switch connected to the first end of the capacitor and turned on in order to supply the sustain voltage to the first end of the capacitor; and a fourth switch directly connected to the first end of the capacitor and turned on in order to supply the reference voltage to the first end of the capacitor.
