1. A driving method of a plasma display panel having an address electrode, a scan electrode and a sustain electrode wherein one frame is divided into a reset period, an address period and a sustain period, comprising:
applying a setup voltage with a first gradient to the scan electrode for the reset period; and
applying the setup voltage with a second gradient to the sustain electrode while a voltage on the scan electrode rises for the reset period.
