Abstract

In a planar ac plasma panel, display cells are formed by the intersection of row and column conductors which are embedded at lower and upper levels, respectively, in a single dielectric layer which adjoins an ionizable display gas. A glow suppression pad, embedded at the upper level, is located adjacent each display cell. The glow suppression pad is capacitively biased from the row and column electrodes at a voltage which prevents unwanted ionization of the display gas between adjacent display cells.
