Plasma display panel driving method and plasma display panel device therefor

Claim 1

A method of driving a plasma display panel device which is comprised of a plurality of first electrodes and a plurality of second electrodes covered with a dielectric layer, and a plurality of third electrodes disposed so as to extend orthogonally to at least one of said first and second electrodes to thereby define individual cells, respectively, wherein a plurality of fields for image display each comprise at least two types of subfields including first and second subfields; said first subfield comprising: a first reset period in which a priming pulse having a voltage value and a pulse width for causing discharge to occur in all of said cells defined between said first electrodes and said second electrodes is applied and after the discharge of all of said cells, a voltage applied between said first and second electrodes is set to zero for erasing wall charge stored in said dielectric layer; an addressing period in which a write operation is performed by bringing about electric discharge between said first or second electrodes and said third electrodes for thereby allowing the wall charge to be stored in said dielectric layer; and a sustained discharge period in which an AC voltage is applied between said first and second electrodes for thereby realizing a sustained discharge by making use of said wall charge stored in said dielectric layer; and said second subfield comprising: a second reset period in which an erasing pulse having a voltage value and a pulse width for causing only the cells discharged in the preceding subfield to be discharged is applied for allowing only the cells discharged in the preceding subfield to be discharged and thereafter the wall charge stored in said dielectric layer is erased by setting to zero the voltage applied between said first and second electrodes; a second addressing period in which a write operation is performed by causing discharge to take place between said first or second electrodes and said third electrodes to thereby store the wall charge in said dielectric layer; and a second sustained discharge period in which an AC voltage is applied between said first and second electrodes for realizing a sustained discharge by making use of the wall charge stored in said dielectric layer.
