Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
150 words
A flat-panel display, comprising a self-supporting, gas-impervious, rigid glass pane having a peripheral portion surrounding a viewing area therein, an electrode display structure positioned adjacent said viewing area of said pane, a gas-impervious metallic rear sheet overlying said electrode structure, sealing means hermetically sealing said rear sheet to said peripheral portion of said pane throughout a continuous area surrounding said viewing area to provide between said pane and said rear sheet a completely enclosed cavity in which said electrode structure is located, the pressure within said cavity being less than the pressure on the external side of said sheet, and said rear sheet being in force transmitting relationship with said electrode structure and sufficiently soft and malleable so as to be deformed and pressed toward said pane by the differential pressure across said sheet to exert a force on said electrode structure to press said electrode structure against said pane.
Claim 2
Dependent Claim
150 words
A flat-panel display, comprising a self-supporting, gas-impervious, rigid glass pane having a peripheral portion surrounding a viewing area therein, an electrode display structure positioned adjacent said viewing area of said pane, a gas-impervious metallic rear sheet overlying said electrode structure, sealing means hermetically sealing said rear sheet to said peripheral portion of said pane throughout a continuous area surrounding said viewing area to provide between said pane and said rear sheet a completely enclosed cavity in which said electrode structure is located, the pressure within said cavity being less than the pressure on the external side of said sheet, and said rear sheet being in force transmitting relationship with said electrode structure and sufficiently soft and malleable so as to be deformed and pressed toward said pane by the differential pressure across said sheet to exert a force on said electrode structure to press said electrode structure against said pane.
Claim 3
Dependent Claim
29 words
A flat-panel display according to claim 1, comprising a compressible member overlying the rear side of said electrode structure and disposed between said electrode structure and said rear sheet.
Claim 4
Dependent Claim
16 words
A flat-panel display according to claim 1, wherein said rear sheet comprises a thin, metal foil.
Claim 5
Dependent Claim
16 words
A flat-panel display according to claim 2, wherein said rear sheet comprises a thin, metal foil.
Claim 6
Dependent Claim
35 words
A flat-panel display according to claim 1, wherein said electrode structure is sufficiently compliant so as to conform substantially to said pane when pressed against said pane by the pressure differential across said rear sheet.
Claim 7
Dependent Claim
29 words
A flat-panel display according to claim 5, comprising a compressible member overlying the rear side of said electrode structure and disposed between said electrode structure and said rear sheet.
Claim 8
Dependent Claim
14 words
A flat-panel display according to claim 6, wherein said compressible member is an insulator.
Claim 9
Dependent Claim
15 words
A flat-panel display according to claim 6, wherein said compressible member is a fibrous mat.
Claim 10
Dependent Claim
21 words
A flat-panel display according to claim 5, comprising getter means mounted in said cavity for removing reactive gases from said display.
Claim 11
Dependent Claim
51 words
A flat-panel display according to claim 1 comprising a rigid member sealed to the peripheral portion of said pane, and a plurality of conductive elements connected at one end to said electrode structure and extending out of said display between said rigid pane and the adjacent surface of said rigid member.
Claim 12
Dependent Claim
39 words
A flat-panel display according to claim 10, wherein said pane and said rigid member are pieces of glass cut from the same sheet of glass, whereby said pane and said rigid member have closely similar coefficients of thermal expansion.
Claim 13
Dependent Claim
16 words
A flat panel display according to claim 10, comprising a tubulation extending through said rigid member.
Claim 14
Dependent Claim
14 words
A flat-panel display according to claim 1, comprising a tubulation extending into said cavity.
Claim 15
Dependent Claim
30 words
A flat-panel display according to claim 5, wherein said rear sheet is preformed with a recess on one side prior to assembly of said rear sheet over said electrode structure.
Claim 16
Dependent Claim
14 words
A flat-panel display according to claim 14, wherein said rear sheet is partially corrugated.
Claim 17
Dependent Claim
49 words
A flat-panel display according to claim 1, comprising a plurality of spaced apart conductors printed on the inner face of said pane, said conductors each having one end connected to said electrode structure and the other end disposed externally of the seal between said pane and said rear sheet.
Claim 18
Dependent Claim
21 words
A flat-panel display according to claim 1, wherein said electrode structure is printed on the inner face of said glass pane.
Claim 19
Dependent Claim
20 words
A flat-panel display according to claim 1, wherein said electrode structure is bonded to the inner face of said pane.
