Abstract
Abstract A flat-panel display is constructed by sealing a metal flange to a frame on a glass pane, then mounting an electrode structure against the pane within the frame, then placing an impervious malleable sheet over the electrode structure, then sealing the sheet to the flange, and then pumping air from the space between the sheet and the glass pane, and backfilling as required.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
80 words
A method of manufacturing a flat-panel display, comprising the steps of hermetically sealing an impervious flange to a continuous area of one surface of a panel member, said area surrounding a viewing area of said panel member, then positioning a display-producing structure against said one face of said panel member over said viewing area, then positioning an impervious sheet over said display producing structure, and then sealing said sheet to said flange along a continuous area surrounding said display-producing structure.
Claim 2
Independent Claim
80 words
A method of manufacturing a flat-panel display, comprising the steps of hermetically sealing an impervious flange to a continuous area of one surface of a panel member, said area surrounding a viewing area of said panel member, then positioning a display-producing structure against said one face of said panel member over said viewing area, then positioning an impervious sheet over said display producing structure, and then sealing said sheet to said flange along a continuous area surrounding said display-producing structure.
Claim 3
Dependent Claim
29 words
A method according to claim 1 wherein said flange is malleable, and comprising the further step of reducing the pressure between said sheet and said panel member below atmospheric.
Claim 4
Dependent Claim
32 words
A method according to claim 2 wherein said step of sealing said sheet to said flange is carried out after said step of reducing the pressure between said sheet and said panel.
Claim 5
Dependent Claim
36 words
A method according to claim 1 wherein, said step of sealing said flange to said panel member is carried out by sealing a continuous frame to said panel member and sealing said flange to said frame.
Claim 6
Dependent Claim
50 words
A method according to claim 4 wherein said frame and said panel member are glass, and said steps of sealing said frame to said panel member and said flange to said frame are carried out at temperatures at which said display-producing structure would be damaged if it were exposed thereto.
Claim 7
Dependent Claim
34 words
A method according to claim 5 comprising the step of placing a blanket over said display structure and said frame prior to said step of positioning said impervious sheet over said display producing structure.
Claim 8
Dependent Claim
32 words
A method according to claim 6 comprising the step of placing a stress distributing member over said blanket prior to said step of positioning said impervious sheet over said display producing structure.
