ABSTRACT:
A flat-panel gas discharge display operable with either alternating or direct current is free of implosive forces because it operates at least at substantially atmospheric pressure. The display comprises a first set of conductors disposed on a transparent substrate and a second set crossing over the first set at a distance therefrom. An array of crosspoints is formed at each location where a conductor of the second set crosses over a conductor of the first set. A gas is contained in the space between the first and second sets of conductors at each crosspoint. The gas will undergo light emissive discharge when a voltage greater than or equal to the Paschen minimum firing voltage is applied at a crosspoint. Air may be used as the operative gas. The display is formed on a single substrate, and may be stacked with additional displays in lieu of one or more capping layers. At least one of the sets of conductors may be provided with an aperture at each of the crosspoints to facilitate viewing the discharge. A system incorporating the flat-panel display is presented. A suitably wired flat-panel structure may constitute a flat-panel plasma discharge lamp for lighting applications.
