A positive column gas discharge plasma display device with one or more ionizable gas filled elongated Plasma-tubes. The display may be a dual substrate or a single substrate device. One or more substrates may be of a flexible material. The ionizable gas produces photons in the UV, IR, and/or visible range during gas discharge. An impervious barrier is positioned between the gas discharge cells in adjacent tubes to minimize or prevent optical cross-talk between pixels in adjacent tubes. The photons may excite one or more luminescent materials located on or in close proximity to one or more Plasma-tubes. The plasma display device may contain at least one Plasma-shell filled with an ionizable gas that produces photons in the UV, IR, and/or visible range during gas discharge. Plasma-shell includes Plasma-disc, Plasma-dome, and Plasma-sphere.
In a gas discharge plasma display having a plurality of elongated tubes with each tube containing a multiplicity of gas discharge cells, the improvement wherein each cell has a positive column gas discharge and there is an impervious barrier between the gas discharge cells in adjacent tubes to minimize or prevent optical cross-talk between cells in said adjacent tubes.
As an article of manufacture, a positive column plasma single substrate display comprising a plurality of elongated tubes, each said tube being located on a single substrate and containing a multiplicity of gas discharge cells, an impervious barrier being located between the gas discharge cells in adjacent tubes to minimize or prevent optical cross-talk between cells in said adjacent tubes.
In the operation of a gas discharge plasma display comprising a plurality of elongated tubes with each tube containing a multiplicity of gas discharge cells, the improvement which comprises operating each cell with a positive column discharge with an impervious barrier being located between the positive column discharge cells in adjacent tubes to minimize or prevent cross-talk between cells in said adjacent tubes.
