Abstract: The present invention relates to a plasma display panel, and more particularly, to a plasma display apparatus and a method of driving a plasma display panel including address electrodes (X) and scan electrodes (Y). The plasma display apparatus according to the present invention includes a plasma display panel including a plurality of scan electrodes and a plurality of address electrodes formed to cross the scan electrodes; a driving unit for driving the plurality of address electrodes; and a driving pulse controller for controlling the driving unit so that a voltage falling time of a data pulse supplied to one and more address electrode groups among a plurality of address electrode groups including one or more address electrodes in an address period ranges from no less than 50 ns to no more than 300 ns. According to The present invention, electric potential of the data pulse varies slowly by prolonging a voltage falling time of a data pulse compared with a conventional voltage falling time so that the peak value of a displacement current becomes reduced. Accordingly, an EMI (ElectroMagnetic Interference) property is enhanced, thereby ensuring normal operations of a driving apparatus of a plasma display panel.
