Patent ID: 7817112

Claim:
A plasma display apparatus, comprising: an apparatus for driving a scan electrode in which reset discharging occur by a first reset pulse which has an ascending ramp signal during a first reset period and second reset pulse which has a descending ramp signal during a second reset period, wherein a highest voltage of the second reset pulse is lower than that of the first reset pulse, a lowest voltage applied to the scan electrodes in the address period is lower than a lowest voltage of the first reset period and the second reset period, a highest voltage applied to the scan electrodes in the address period is higher than a lowest voltage applied to the scan electrodes in the first reset period and the second reset period and a lowest voltage applied to the scan electrodes in a sustain period, and wherein a voltage applied to the scan electrode at a starting point of the sustain period drops from the highest voltage applied to the scan electrode in the address period to the lowest voltage applied to the scan electrode in the sustain period, wherein the lowest voltage applied to the scan electrodes in the sustain period is lower than the highest voltage applied to the scan electrode in the address period, and is higher than the lowest voltage applied to the scan electrode in the address period.
