Abstract
A high-resolution flat-panel plasma display device made in solid-state form and designed for large-area full-color applications includes first and second sets of orthogonally disposed electrodes on a substrate to which a phosphor-containing faceplate is sealed. The electrodes of one set are respectively suspended relatively high above the substrate surface on spaced-apart longitudinally extending dielectric ridges.
Claims14
A display device comprising:
- a substrate including
- a first set of spaced-apart longitudinally extending electrodes on the surface of said substrate,
- spaced-apart longitudinally extending dielectric ridges overlying said electrodes and said substrate surface and disposed orthogonally with respect to said first set of electrodes to form longitudinally extending trenches between said ridges,
- a second set of spaced-apart longitudinally extending electrodes each positioned on a different one of said ridges,
- a dielectric layer overlying said substrate surface, said first and second set of electrodes and said ridges to only partially fill said trenches, said partially filled trenches providing distribution channels into which an ionizable gas may be introduced,
- and a faceplate sealed to said substrate, said faceplate having spaced-apart phosphor regions respectively overlying intersections defined by said first and second sets of electrodes on said substrate.
