Abstract
A single substrate AC and/or DC gas discharge (plasma) display device with hollow shells containing ionizable gas at a predetermined pressure, each shell being positioned on the surface of the substrate or within a substrate cavity, well, or hollow. Each shell is in electrical contact with at least one electrode, typically two, three, or more electrodes. The AC or DC gas discharge within each shell emits photons in the visible and/or invisible range. In one embodiment, photons from the gas discharge within a shell excite a luminescent substance or material such as a phosphor that emits photons in the visible and/or invisible spectrum. The shell may contain the luminescent substance or the substance may be located separately from, but in close proximity to the shell.
Claims8
A process for manufacturing a gas discharge device comprising a multiplicity of gas filled shells positioned on a single substrate, each shell being selectively filled with an ionizable gas containing luminescent particles suspended in the gas, said suspended luminescent particles being selected to be excited by photons from a discharge of the gas within a shell while suspended in the gas, and a multiplicity of said gas filled shells containing said suspended luminescent particles being positioned on a single substrate in contact with at least one electrode.
