Abstract
A plasma display panel with quick firing nature and high speed scanning having a plurality of display cells defined by parallel cathode electrodes and parallel anode electrodes perpendicular to said cathode electrodes. The cells along a cathode electrode discharge simultaneously either strongly or weakly according to the currents in the anode electrodes, and said current in the anode electrodes is switched according to the picture pattern to be displayed. A strongly discharged cell provides a bright large discharge which is visible through a cathode electrode, and a weakly discharged cell provides a dark small discharge which is blinded by a cathode electrode itself and is invisible, but merely functions as a seed cell for firing adjacent cells. As all the cells function both as display cells and seed cells, quick firing of cells or high speed scanning of light spots along the anode electrodes is accomplished although no specific seed electrode for mere seed discharge is provided. And, density of cells or resolution power of a picture of the present invention is improved, as no specific seed electrode is provided.
