There is provided a plasma display device. The plasma display device includes a plasma display panel (PDP) and drivers for supplying driving signals to the PDP. The driver includes a capacitor, a first switch turned on in order to supply a voltage of a first end of both ends of the capacitor to the PDP, a second switch turned on in order to supply a voltage of a second end of both ends 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, and a second voltage supplier connected to the second end of the capacitor to supply the reference voltage to the second end. A voltage difference between the both ends of the capacitor is sustained as the sustain voltage. In the plasma display device, since the conventional large capacity of pass switch and the negative polar scan voltage source&#x2014;Yy are replaced by cheap capacitors with the driving signals for driving the PDP applied in the same way, it is possible to reduce the manufacturing cost of the plasma display device.

Plasma display device

The present invention relates to a plasma display apparatus and driving method thereof. The plasma display apparatus according to an embodiment of the present invention comprises a plasma display panel comprising a scan electrode and a sustain electrode, and a driver that controls one or more of sustain pulses supplied to the scan electrode and one or more of sustain pulses supplied to the sustain electrode to be overlapped with each other.
