ABSTRACT:
There is disclosed a gaseous discharge display device having a plurality of gaseous discharge sites and at least one active, working dielectric surface exposed to the gas discharge at each discharge site. The active gas contacting dielectric surface is coated with a protective film in an amount sufficient to prevent the formation of undesirable contaminants on the active dielectric surface, particularly during the manufacture of the device. After the complete assembly and gas filling of the device, the protective film is removed from the vicinity of each gas discharge site by the application of a gas discharge voltage at the site sufficient to sputter the protective film away from the discharge site without sputtering the active dielectric surface.
