ABSTRACT:
There is disclosed a gas discharge display device comprised of microspheres containing ionizable gas, each microsphere being positioned within a cavity, well, or hollow. Photons from the gas discharge within a microsphere excite a phosphor such that the phosphor emits wavelengths in the visible and/or invisible spectrum. The invention is described in detail with reference to an AC gas discharge (plasma) display.
