Abstract:
A method of driving, during a write discharge period, a matrix type plasma display panel having a plurality of display cells, said panel additionally comprising; a plurality of row electrode pairs, each said row electrode pair comprising a scan electrode and a sustaining electrode, said panel additionally comprising a plurality of data electrodes perpendicular to said row electrode pairs, said method comprising:applying a composite scan pulse sequentially to said scan electrodes, said composite scan pulse comprising a first non-zero voltage level for a first predetermined time interval, followed by a second non-zero voltage for a second predetermined time interval, said second non-zero voltage being different from said first non-zero voltage level, followed by a third non-zero voltage level, said third non-zero voltage level being different from both said first non-zero voltage level and said second non-zero voltage level, wherein said composite scan pulse comprises an auxiliary scan pulse as said first non-zero voltage level opposite in polarity to said second non-zero voltage level, said second level comprising a scan pulse, and wherein a data pulse is selectively supplied to said data electrodes in synchronism with said scan pulse.
