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.
Claims29
In a gas discharge plasma display device having a multiplicity of gas discharge pixels, the improvement wherein each pixel is defined by a hollow microsphere filled with ionizable gas at a predetermined pressure, said microsphere having an internal surface with phosphor located on all or part of said internal surface, each said microsphere being positioned within a cavity, well, or hollow.
In an AC gas discharge display panel having a pair of opposing substrates and a multiplicity of gas discharge pixels, each pixel being defined by a hollow microsphere filled with ionizable gas, the improvement wherein at least one substrate has a multiplicity of cavities, wells, or hollows and wherein a microsphere is positioned in each cavity, well, or hollow.
In an AC gas discharge display panel having a pair of opposing substrates and a multiplicity of gas discharge pixels, each pixel being defined by a hollow microsphere filled with ionizable gas, the improvement wherein at least one substrate is composed of a flexible material and wherein at least one substrate has a multiplicity of cavities, wells, or hollows and wherein a microsphere is positioned within each cavity, well, or hollow.
In a gas discharge display device having a multiplicity of gas discharge pixels, the improvement wherein each pixel is defined by a hollow microsphere filled with an ionizable gas at a predetermined pressure with phosphor particles being dispersed or floating with said gas, each said microsphere being positioned within a cavity, well, or hollow.
