Abstract A high contrast plasma display device includes transparent and opaque insulator layers spaced and bonded by a plurality of spaced opaque insulator segments forming a plurality of cavities. An insulator substrate having a plurality of spaced conductors on the surface thereof in registry with the cavities and electrical connectors embedded therein is bonded to the opaque insulator layer while a transparent electrode layer is affixed to the transparent insulator layer. An ionizable gas is disposed within the cavities whereby energization of certain conductors alters the device from an opaque to a visual display. Also, the high contrast plasma display device is fabricated by a process which includes affixing the spaced conductor to a substrate, bonding an opaque insulator layer to the substrate and spaced conductors, attaching spaced opaque insulator segments to a transparent insulator layer, bonding the segments to the opaque insulator layer forming cavities in registry with the spaced conductors, affixing a transparent electrode to the transparent insulator layer, and disposing an ionizable gas within the cavities whereby the device appears opaque until energized to provide a visual display.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
A high contrast plasma display device comprising in combination: spaced transparent and opaque insulator layers; spaced opaque insulator segments bonded to and separating said layers and forming a plurality of independent cavities intermediate thereto and said layers; an insulator substrate affixed to said opaque layer and having plurality of connectors embedded therein and passing therethrough to contact a like plurality of spaced conductors affixed to said substrate in registry with said cavities and embedded in said opaque layer; a transparent electrode layer affixed to said transparent insulator layer on the surface remote from said spaced connectors and a phosphor layer affixed to the opposite surface of said transparent electrode layer; an ionizable gas disposed within said cavities whereby energization of said spaced conductors causes ionization of said gas within said cavities aligned therewith and alteration in the appearance of said device from opaque to a visual display when viewed through said transparent insulator layer; and a seal intermediate the periphery of the spaced transparent and opaque insulator layers.
Claim 2
Dependent Claim
