Claim 1
Independent Claim
194 words
A display panel comprising a gas-filled envelope including a base plate and face plate hermetically sealed together, a plurality of vertical conductive strips positioned on the top surface of said base plate, a first layer of insulating material covering said conductive strips and including first apertures disposed in series along each of said conductive strips, each first aperture exposing a dot-like portion of the associated strip which is operable as a cathode electrode, said dot-like cathode electrodes being arrayed in rows and columns, a second layer of insulated material on said first layer and having a plurality of horizontal slots, each aligned with a row of said cathode electrodes, a plurality of horizontal strips of transparent conductive material on the inner surface of said face plate, each such strip overlaying one of said horizontal slots in said second layer, and an opaque conductive layer on each of said horizontal strips and having a series of second apertures therein, each second aperture exposing a dot-like area of its horizontal strip which is operable as an anode electrode, each such anode electrode being vertically aligned with and in operative relation with one of said cathode electrodes.
Claim 2
Dependent Claim
194 words
A display panel comprising a gas-filled envelope including a base plate and face plate hermetically sealed together, a plurality of vertical conductive strips positioned on the top surface of said base plate, a first layer of insulating material covering said conductive strips and including first apertures disposed in series along each of said conductive strips, each first aperture exposing a dot-like portion of the associated strip which is operable as a cathode electrode, said dot-like cathode electrodes being arrayed in rows and columns, a second layer of insulated material on said first layer and having a plurality of horizontal slots, each aligned with a row of said cathode electrodes, a plurality of horizontal strips of transparent conductive material on the inner surface of said face plate, each such strip overlaying one of said horizontal slots in said second layer, and an opaque conductive layer on each of said horizontal strips and having a series of second apertures therein, each second aperture exposing a dot-like area of its horizontal strip which is operable as an anode electrode, each such anode electrode being vertically aligned with and in operative relation with one of said cathode electrodes.
Claim 3
Dependent Claim
29 words
The panel defined in claim 1 and including a phosphor material in each of said second apertures in contact with at least a portion of the anode electrode therein.
Claim 4
Dependent Claim
22 words
The panel defined in claim 2 wherein said phosphor material is provided as concentric rings between which the anode electrode is exposed.
Claim 5
Dependent Claim
15 words
The panel defined in claim 1 wherein said first apertures are generally oval in shape.
Claim 6
Dependent Claim
61 words
The panel defined in claim 1 wherein said vertical strips include a first, a last, and intermediate strips, the spacing between a plurality of said intermediate strips being smaller than the spacing between others of said strips whereby sufficient spacing may be provided between the first and last strip and the adjacent edges of said panel to form an hermetic seal.
