Plasma-display panel of high luminosity and high efficiency, and a driving method of such a plasma-display panel

A driving method of a plasma-display panel comprising, a first insulator substrate and a second insulator substrate which is arranged at a given distance above the first insulator substrate;

• the first insulator substrate having a first line electrode group and a second line electrode group, with the electrodes being arranged in parallel in each group, and the second insulator substrate having a third line electrode group which has parallel electrodes passing over the first line electrode group at right angles so that the third line electrode group and the first line electrode group appear to form a two-dimensional lattice when viewed from above;
• thereby forming a discharge space between the first insulator substrate and the second insulator substrate;
• the first line electrode group and the third line electrode group having parts exposed to the discharge space, while the second line electrode group being covered by a dielectric layer in the discharge space;
• the method comprising the steps of:
• addressing for writing image information by providing an addressing discharge between the first electrode group and the third line electrode group and accumulating charges on the dielectric layer by applying a voltage below a discharge voltage to the second line electrode group;
• and
• discharge sustaining after said addressing for detaching the charges from the dielectric layer so as to float them in the discharge space by applying an auxiliary pulse voltage to the second electrode group, and generating a direct current discharge by applying a sustain pulse voltage in-between the first line electrode group and the third line electrode group.
