Plasma display apparatus and driving method of the same

An apparatus for driving a plasma display panel in which a plurality of scan electrodes and sustain electrodes are formed on a top substrate to make pairs, the apparatus comprising:

• electrode driving parts for driving the scan electrodes and the sustain electrodes;
• and
• a sustain pulse control part for controlling the driving parts such that the width of the sustain pulse applied to the scan electrodes or the sustain electrodes, in the sustain period of the sub-field that displays the lowermost gray scales, is smaller than the width of the sustain pulses of the sub-fields that display the other gray scales.
