    Abstract: A D.C. gas discharge display panel for operation in a storage mode with internal memory, comprises a gas filled envelope bounded by a pair of glass plates (2 and 3), which carry on their respective internal surfaces orthogonal arrays of cathode conductors (4) and anode conductors (6) separated by a discharge gap (30). The array of cathode conductors is covered by a layer (10) of resistive material, which in turn is covered by a cermet layer (12). The cermet layer protects the cathode conductors from ion bombardment induced sputtering during discharge. The layers provide a resistance to each discharge cell, and provide isolation between individual cathodes by reducing discharge spreading along the cathode conductors and preventing surface charge build-up during panel operation. By using a combination of metal and insulator in the resistance layer, the D.C. discharge can be sustained at lower operating voltage, permitting a reduction in the power requirements of the panel.

    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.
