Patent ID: 7839360

Claim:
A plasma display apparatus, comprising: a plasma display panel having scan electrodes being applied reset pulse and scan pulse; and an apparatus for driving the scan electrodes in which a lowest level of the voltage applied to the scan electrodes during an address period is less than a lowest level of the voltage applied to the scan electrodes during a reset period, a highest voltage applied to the scan electrodes during the address period is positive and greater than the lowest level of the voltage applied to the scan electrodes during the reset period, a lowest level of the voltage applied to the scan electrodes during a reset period is negative, and a level of starting voltage during the sustain period is equal to a level of ending voltage during the sustain period, wherein the lowest level of a descending ramp signal applied to the scan electrode during the reset period is equal to the lowest level of the voltage applied to the scan electrode during a sustain period, and the levels of voltage applied to the scan electrode during the address period have a first level of voltage and a second level of voltage, wherein the first level of voltage is less than the lowest level of the voltage applied to the scan electrode during the sustain period, and the second level of voltage is greater than the lowest level of the voltage applied to the scan electrode during the sustain period, and is less than the highest level of the voltage applied to the scan electrode during the sustain period.
