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.

Manufacturing process for plasma-shell gas discharge device

A single substrate AC and/or DC gas discharge (plasma) display device comprised of hollow microspheres containing ionizable gas at a predetermined pressure, each microsphere being positioned on the surface of the substrate or within a substrate cavity, well, or hollow. Each microsphere is in electrical contact with 2, 3, or more electrodes. The AC or DC gas discharge within each microsphere emits photons in the visible and/or invisible range. In one embodiment, photons from the gas discharge within a microsphere excite a luminescent substance or material such as a phosphor that emits photons in the visible and/or invisible spectrum. The microsphere may contain the luminescent substance or the substance may be located separately from, but in close proximity to, the microsphere.

Gas discharge display

A plasma panel device having a multiplicity of gas filled plasma-shells, each plasma-shell being positioned on or in a substrate and electrically connected to conductors or electrodes to define a gas discharge pixel or subpixel. The plasma-shell comprises a hollow gas filled geometric body and includes plasma-disc, plasma-dome, plasma-sphere, and other geometric shapes. The substrate may be rigid, flexible, or semi-flexible with a flat, curved, or irregular surface. Each substrate may comprise a single layer or multiple layers of the same or different materials. Substrate composites may be used such as mixtures, dispersions, suspensions, and so forth. The device may comprise a single substrate or a dual substrate device. A plasma-shell device with a flexible substrate may be bendable and rollable in at least two directions, X and Y, looking at the top or plan view.

Plasma-shell device

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.

This invention comprises the use of microspheres containing ionizable gas in a gas discharge (plasma) display, photons for the gas discharge within a microsphere exciting a phosphor such that the phosphor emits wavelengths in both the visible or invisible spectrum. The invention is described in detail hereinafter with reference to an AC gas discharge (plasma) display.
