Abstract
A gaseous discharge display and/or memory device comprises a pair of sealed glass plates having metallic conductor arrays formed thereon and insulated from contact with the gas by a dielectric layer. The crossover points of the conductors define the locations of the individual cells which are controlled by selective application of write, sustain, and erase signals. To permit uniform operation of individual cells, the plates must be maintained precisely spaced over their entire display surface. To effect this requirement in a large size panel, metallic spacers are secured to the upper surface of the conductors of the metallic conductor arrays prior to the formation of the dielectric layer, the size and number of these spacers being determined by the geometry and resolution of the gaseous discharge display device.
