US Patent 7733303 Plasma display apparatus and method of driving the same

A plasma display apparatus and a method of driving the same are disclosed. In the method, a first pulse of a positive polarity direction and a second pulse of a negative polarity direction are alternately supplied to the first electrode during a sustain period. In this case, an absolute value of a voltage of the first pulse is different from an absolute value of a voltage of the second pulse. A third pulse of a positive polarity direction to the third electrode is supplied during the supply of the first pulse, and a fourth pulse having a sum of a voltage magnitude of the third pulse and a voltage magnitude of the second pulse is supplied to the third electrode during the supply of the second pulse.
