Abstract
There is provided a plasma display apparatus and a driving method of a plasma display panel. The plasma display apparatus comprises a plasma display panel comprising a first electrode and a second electrode, and an electrode driver alternatively applying a sustain pulse of a first polarity to the first electrode and the second electrode and applying a pulse of a second polarity opposite to a first polarity after a magnitude of a voltage of a sustain pulse of a first polarity is maximized. Therefore, it is possible to increase discharge efficiency without rising a driving voltage or increasing an electrode space by increasing an amount of space discharge.
