An apparatus and method to drive a Plasma Display Panel (PDP) having discharge cells arranged where X electrodes and Y electrodes cross each other includes: generating a driving control signal including X, Y, and A driving control signals according to an image signal of an image to be displayed; X, Y, and A drivers to respectively process the X, Y, and A driving control signals and to supply them to the X, Y, and A electrodes. In a sustain-discharge period, a sustain pulse voltage of a first level is alternately supplied to the X electrodes and the Y electrodes, and a first sustain pulse has a pulse width in a range between 3 μs and 10 μs.
