Abstract (en)
A display system and operating method in which ultraviolet radiation is produced and made to impinge on fluorescent phosphors (54) and visible through translucent protective layer (62). The ultraviolet radiation is generated by application of a potential between the cathode cells and annular anodes (46) spaced therefrom by a dielectric film (38) having apertures (44) therein aligned with the cathode cells. The assembly is hermetically sealed by a reflective backing panel (64) which defines a chamber (66) communicating with the cathode cells (22) and containing an inert gas. Display is initiated by application of a first potential across the anodes and cathodes. Ions produced in the gaseous medium impinge on the metallic coating (28) and sputter metal atoms therefrom which ionize under a second applied potential thereby to produce the ultraviolet radiation for conversion into visible radiation by the fluorescent phosphors (54).
