ABSTRACT:
A plasma display apparatus comprises a plasma display panel, a sustain driver, a data driver and a reference separation controller. The plasma display panel including a first electrode, a second electrode and a third electrode crossing the first electrode and the second electrode. The sustain driver supplying a sustain signal swinging between a positive polarity sustain voltage and a negative polarity sustain voltage to the first electrode during a sustain period. The data driver supplying a data signal to the third electrode during an address period. The reference separation controller controlling a first reference voltage source, which is connected with the sustain driver and the second electrode commonly, separated from or connected with a second reference voltage source which is connected with the data driver.
