A PDP constructed out of one or more Plasma-shells with a luminescent substance(s) located in close proximity to each Plasma-shell. The luminescent substance comprises a combination of an organic luminescent substance and an inorganic luminescent substance. The combination may be a mixture of organic and inorganic substances. Layers of organic and inorganic substances may be used. Each Plasma-shell is a hollow geometric body filled with an ionizable gas at a suitable pressure. Photons from the gas discharge inside the Plasma-shell excite the luminescent substance. In one embodiment the luminescent substance is located on the external surface of the Plasma-shell. In another embodiment, the luminescent substance is located inside the Plasma-shell. Plasma-shell includes Plasma-sphere, Plasma-disc, and Plasma-dome. The Plasma-shell may be used in combination with a Plasma-tube.
In gas discharge plasma display having one or more gas discharge pixels, the improvement wherein each pixel is defined by a Plasma-she containing an ionizable gas and wherein a luminescent substance is located in close proximity to each Plasma-shell so as to be excited by photons from a gas discharge within the Plasma-shell, said luminescent substance comprising a combination of an inorganic luminescent substance and an organic luminescent substance, a source of secondary electron emission being provided inside of the Plasma-shell.
In a single substrate PDP comprising a multiplicity of pixels, the improvement wherein each pixel is defined by an ionizable gas filled Plasma-shell with two or more electrodes in electrical contact with each Plasma-shell, a luminescent substance being located in close proximity to each Plasma-shell so as to be excited by photons from a gas discharge within the Plasma-shell, said luminescent substance comprising an inorganic luminescent substance and an organic luminescent substance combined together, a source of secondary electron emission being provided inside of the Plasma-shell.
