Abstract:
1. A method of driving a plasma display panel using ADS method comprising a reset period including an erase period, a rising period and a falling period, an address period and a sustain period, in which an auxiliary electrode is inserted between a scan electrode and a sustain electrode which are disposed in parallel on a front substrate, while an address electrode is disposed on a rear substrate facing the front substrate, the method comprising: applying an erase pulse which rises from a first voltage to a second voltage to the auxiliary electrode in the erase period; applying a predetermined voltage to the sustain electrode in order that the potential difference with respect to the scan electrode maintains a smaller voltage than a firing voltage, while the auxiliary electrode maintains at least a ground voltage while increasing the voltage which is applied to the scan electrode in the rising period; and respectively applying the predetermined voltage to the auxiliary electrode and the sustain electrode while decreasing the voltage which is applied to the scan electrode in the falling period.
