Abstract
Methods for driving an AC discharge memory-type plasma display panel having a scanning electrode, a sustaining electrode and a data electrode, in which a driving pulse can be applied so that temporal separation of opposing discharge from surface discharge in erasing discharge during a sustaining charge erasing period is achieved to solve problems that, if opposing discharge and surface discharge occur simultaneously during the sustaining erasing discharge, control on electric charges is difficult in operations containing, at least, a writing period and a sustaining period, causing a malfunction during the writing and sustaining periods.
