disclosed is a method of driving a plasma display panel and apparatus thereof enabling to minimize power consumption for driving the plasma display panel . 1 . the present invention includes the steps of generating a reset discharge by supplying ramp waves so as to equalize cells in the plasma display panel in a reset period , supplying selected specific ones of the cells with a scan voltage pulse swinging between a lowest voltage levels of the reset discharge and a data pulse of a voltage level lowered as much as a negative voltage level of the scan voltage pulse , generating an address discharge by the scan voltage pulse and data pulse applied to the selected cells in an address period , and maintaining the address discharge for a sustain period .
