ABSTRACT:
A plasma-display panel of high luminosity and efficiency which does not require auxiliary cells so that the panel structure has high-density cells, enabling longer emission time and smaller reactive power. A driving method of such a PDP comprising a first insulator substrate and a second insulator substrate which is arranged at a given distance above the first insulator substance; the first insulator substrate having a first line electrode group and a second line electrode group which are parallel, and the second insulator substrate having a third line electrode group which are parallel to the first and the second line electrode groups so that the third line electrode group and the first and the second electrode groups appear to form a two-dimensional lattice when viewed from above; thereby forming a discharge space between the first and the second insulator substrates; the first and the third line electrode groups having parts exposed to the discharge space, while the second line electrode group being covered by dielectric layer in the discharge space. The method comprises: writing image information by addressing discharge between the line electrode groups which appear to form a two-dimensional lattice when viewed from above and accumulating charges on the dielectric layer; and floating the charges in the discharge space by applying an auxiliary pulse voltage below discharge voltage to the second electrode group, and generating direct current discharge by applying a sustain pulse voltage in-between the first and the third line electrode groups.
