Abstract
A PDP driving method. When a first sustain pulse is applied to a scan electrode during a sustain period, an address electrode is biased by a positive voltage, or the address electrode is biased. Therefore, when a large amount of wall charges are formed on the address and scan electrodes by address discharging during an address period, no main discharge is generated since a high potential of the address electrode is formed in the sustain period.
