Abstract
The present invention relates to a drive device and method of a plasma display panel in which the manufacturing cost of a PDP can be reduced. The plasma display panel in accordance with the present invention has a drive device comprising: a IC circuit supplying drive voltage to scan electrodes; a energy recovery circuit supplying sustain voltage to the IC circuit; a set up supply part supplying rising ramp wave form to the IC circuit during set up period; and a set down supply part supplying falling ramp wave form to the IC circuit during set down period, wherein said drive device includes a switch which connects the set up supply part to the set down supply part and is turned on or off responding to voltage supplied to the IC drive circuit during the set down period.
