Abstract:
A method of controlling an alternating current plasma display panel including a plurality of data electrodes covered with a first dielectric structure, a plurality of scanning electrodes covered with a second dielectric structure spaced from said first dielectric structure for forming a space filled with discharging gas and a plurality of sustain electrodes covered with said second dielectric structure and respectively paired with said plurality of scanning electrodes for forming a plurality of electrode pairs, each of said plurality of data electrodes and each of said plurality of electrode pairs defining one of a plurality of pixels selectively fired,said method comprising the steps ofa) applying a scanning pulse sequentially to said plurality of scanning electrodes and a data pulse selectively to said plurality of data electrodes so as to create a first internal potential available for firing in certain pixeles selected from said plurality of pixels, andb) alternately applying a first sustain pulse negative with respect to a potential level on said plurality of data electrodes to said plurality of sustain electrodes and said plurality of scanning electrodes so as to make said certain pixels fired,c) applying a second sustain pulse positive with respect to said potential level on said plurality of data electrodes to either sustain or scanning electrodes so as to accumulate wall charges on said first insulating structure and said second insulating structure for creating a second internal potential expressed by a first electric force line directed from said first insulating structure to said second insulating structure and a second electric force line between a first area of said second insulating structure adjacent to said plurality of scanning electrodes and a second area of said second insulating structure adjacent to said plurality of sustain electrodes, andd) erasing said wall charges from said first insulating structure and said second insulating structure, and in which a first erasing pulse is applied to either sustain or scanning electrodes.
