Filed:

Oct 13, 2004

Appl. No.:

10/964583

Inventors:

Paul Valentine - Hornell NY, US
Doreen D. Edwards - Wellsville NY, US
Lyle H. Slack - Wellsville NY, US
Wayne Douglas Brown - Williamsburg WV, US
Cathy Osborne - Kieffer WV, US
Michael Norton - Huntington WV, US
Richard Begley - Huntington WV, US

International Classification:

H01J 1/52

US Classification:

313509, 313498

Abstract:

A light-emitting ceramic based panel, hereafter termed “electroceramescent” panel, is herein claimed. The electroceramescent panel is formed on a substrate providing mechanical support as well as serving as the base electrode for the device. One or more semiconductive ceramic layers directly overlay the substrate, and electrical conductivity and ionic diffusion are controlled. Light emitting regions overlay the semiconductive ceramic layers, and said regions consist sequentially of a layer of a ceramic insulation layer and an electroluminescent layer, comprised of doped phosphors or the equivalent. One or more conductive top electrode layers having optically transmissive areas overlay the light emitting regions, and a multi-layered top barrier cover comprising one or more optically transmissive non-combustible insulation layers overlay said top electrode regions.

Abstract:

A light-emitting ceramic based panel, hereafter termed “electroceramescent” panel, and alternative methods of fabrication for the same are claimed. The electroceramescent panel is formed on a substrate providing mechanical support as well as serving as the base electrode for the device. One or more semiconductive ceramic layers directly overlay the substrate, and electrical conductivity and ionic diffusion are controlled. Light emitting regions overlay the semiconductive ceramic layers, and said regions consist sequentially of a layer of a ceramic insulation layer and an electroluminescent layer, comprised of doped phosphors or the equivalent. One or more conductive top electrode layers having optically transmissive areas overlay the light emitting regions, and a multi-layered top barrier cover comprising one or more optically transmissive non-combustible insulation layers overlay said top electrode regions.
