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.
A single substrate gas discharge device comprising a multiplicity of pixels, each pixel being defined by a hollow shell filled with an ionizable gas that produces photons during gas discharge when an appropriate voltage is applied to the gas, each of said gas filled shells being located on the surface of a single common substrate and being connected to two or more electrodes for providing voltages to each of said gas filled shells, said electrodes being located on the substrate.
A single substrate gas discharge device comprising a multiplicity of pixels and a single common substrate, each pixel being defined by a hollow shell filled with an ionizable gas, each gas filled shell being positioned on the surface of the common single substrate and being electrically connected to two or more electrodes located on the common substrate, each electrode being electrically connected to appropriate electronic circuitry for providing voltages to each gas filled shell so as to cause a gas discharge within said shell.
In a method of fabricating a single substrate gas discharge device comprising a multiplicity of pixels, the improvement which comprises positioning a multiplicity of ionizable gas filled hollow shells on a surface of a single common substrate, and electrically contacting at least two electrodes to each shell, said electrodes being located on the substrate, each pixel being defined by a gas filled hollow shell of said multiplicity of gas filled hollow shells.
