Abstract
A gas discharge device having one or more substrates and a multiplicity of gas discharge cells, each cell confined within a hollow plasma-shell filled with an ionizable gas. The device contains inorganic and/or organic luminescent materials that are excited by a gas discharge within each plasma-shell. The luminescent material is located on an exterior and/or interior surface of the plasma-shell and/or incorporated into the plasma-shell. Up-conversion and down-conversion materials may be used.
Claims6
A method for producing a gas discharge device having a multiplicity of gas discharge cells, each cell being within a gas-filled plasma-shell, which method comprises:
- locating a multiplicity of plasma-shells on the surface of a substrate, each plasma-shell being made of a luminescent substance comprising a combination of organic and inorganic materials and containing a separate layer of luminescent substance on an exterior surface of the plasma-shell;
- and
- electrically contacting two electrodes to each of said plasma-shells, said electrodes being parallel to each other, each said electrode being connected to electronic circuitry for selectively addressing each plasma-shell with AC or DC gas discharge voltages.
In a gas discharge device having a multiplicity of gas discharge cells, the improvement wherein each cell is within a gas-filled plasma-shell electrically connected to two parallel electrodes, each said plasma-shell being made of a luminescent substance comprising organic and inorganic materials and containing another luminescent substance on an exterior portion of said plasma-shell, each said electrode being connected to electronic circuitry to provide AC or DC voltages to cause a gas discharge within each plasma-shell.
