Abstract:
1. A driving device of a plasma display panel where a panel capacitor is formed by a first electrode and a second electrode and where the plasma display panel is driven in frames, each frame having a plurality of subfields, the driving device comprising: a first switch coupled between the first electrode and a first power source for supplying a first voltage, and gradually raising the voltage of the first electrode at the time of turn-on; and a second switch coupled between the second electrode and a second power source for supplying a second voltage, wherein each subfield has a first reset period followed by an adjacent second reset period followed by an adjacent address period followed by an adjacent sustain period, and wherein in the adjacent second reset period, the first switch is turned on to gradually raise the voltage of the first electrode to a predetermined voltage and the second switch is turned on to apply the second voltage to the second electrode.
