Abstract
Abstract A method and apparatus for making formed glass structures. A glass frit containing material is deposited within a recessed pattern, hardened in the recessed pattern, and transferred to a substrate (22). The method and apparatus of the invention are particularly useful for forming barrier rib structures for use in plasma display panels.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
50 words
A method of making free standing glass structures, comprising: contacting a formable glass, ceramic, or glass-ceramic frit containing material with an intaglio recessed pattern to thereby form said frit containing material into a shape of a desired free-standing structure, and hardening said frit containing material sufficiently to retain said shape.
Claim 2
Dependent Claim
52 words
The method of claim 1, wherein said contacting step comprises: filling said recessed pattern with said glass, ceramic, or glass-ceramic frit containing material; and transferring the frit containing material to a substrate, said frit containing material retaining the shape of the recessed pattern to form a free standing structure on said substrate.
Claim 3
Dependent Claim
45 words
The method of claim 2, wherein said contacting step comprises sufficiently hardening at least a portion of the frit containing material while said frit containing material is retained within said recessed pattern to facilitate said frit containing material retaining the shape of said recessed pattern.
Claim 4
Dependent Claim
38 words
The method of claim 1, wherein, prior to said contacting step, a coating of said frit containing material is deposited onto a substrate and said contacting step comprises contacting said coating on said substrate with said recessed pattern.
Claim 5
Dependent Claim
32 words
The method of claim 4, wherein said frit containing material comprises a thermoplastic organic carrier, and prior to said contacting, said coating is heated to facilitate forming of said frit containing material.
Claim 6
Dependent Claim
59 words
A method of making a rib structure for use in a flat panel display in accordance with claim 1, wherein said frit containing material further comprises a crystalline filler therein, and the average coefficient of thermal expansion of the frit containing material is about 35-45 X 10 -7 /° C over the temperature range of 0 to 300° C.
Claim 7
Dependent Claim
58 words
A method of making a rib structure for use in a plasma emissive display in accordance with claim 1, wherein said frit containing material comprises a crystalline filler therein, and the average coefficient of thermal expansion of the frit containing material is about 80-85 X 10 -7 /° C over the temperature range of 0 to 300° C.
Claim 8
Dependent Claim
21 words
The method of claim 1, wherein said frit comprises a glass frit having a softening point less than about 500° C.
Claim 9
Dependent Claim
24 words
The method of claim 1, wherein said frit comprises a glass frit selected from the group consisting of phosphate, lead, and zinc based glasses.
Claim 10
Dependent Claim
34 words
The method of claim 1, wherein said frit containing material in said transferring step comprises at least 55 percent of a glass, ceramic, glass-ceramic, or other inorganic material dispersed within an organic carrier material.
Claim 11
Dependent Claim
17 words
The method of claim 10, wherein said organic material is hardenable via radiation curing, drying, or heat.
Claim 12
Dependent Claim
21 words
The method of claim 10, wherein said organic material is curable material, and said transferring step comprises curing said organic material.
Claim 13
Dependent Claim
33 words
The method of claim 10, wherein said organic material is radiation curable, and said transferring step comprises emitting radiation through said substrate to cure said frit containing material simultaneous with said transferring step.
Claim 14
Dependent Claim
25 words
The method of claim 1, further comprising firing said formed glass mixture and said substrate at a temperature which is sufficient to fuse said frit.
Claim 15
Dependent Claim
31 words
The method of claim 14, further comprising, prior to said firing step, applying a material between said freestanding structures to facilitate said freestanding structures retaining their shape during said firing step.
Claim 16
Dependent Claim
27 words
The method of claim 15, wherein said firing step comprises firing said frit containing material and said substrate at a temperature between about 100 and 600° C.
Claim 17
Dependent Claim
14 words
The method of claim 1, further comprising transferring said freestanding structures to a substrate.
Claim 18
Dependent Claim
24 words
The method of claim 17, wherein said hardening of said glass frit containing material occurs while said material is retained within said recessed pattern.
Claim 19
Dependent Claim
26 words
The method of claim 18, further comprising, prior to said transferring step, applying an adhesive layer either to said glass substrate or said glass frit mixture.
Claim 20
Independent Claim
56 words
A method of making a glass barrier rib plate for a flat panel display, comprising: contacting a formable glass, ceramic, or glass-ceramic frit containing material with an intaglio recessed pattern to thereby form said frit containing material into a shape of a desired free-standing structure, and hardening said frit containing material sufficiently to retain said shape.
Claim 21
Dependent Claim
52 words
The method of claim 20, wherein said contacting step comprises: filling said recessed pattern with said glass, ceramic, or glass-ceramic frit containing material; and transferring the frit containing material to a substrate, said frit containing material retaining the shape of the recessed pattern to form a free standing structure on said substrate.
Claim 22
Dependent Claim
45 words
The method of claim 21, wherein said contacting step comprises sufficiently hardening at least a portion of the frit containing material while said frit containing material is retained within said recessed pattern to facilitate said frit containing material retaining the shape of said recessed pattern.
Claim 23
Dependent Claim
38 words
The method of claim 20, wherein, prior to said contacting step, a coating of said frit containing material is deposited onto a substrate and said contacting step comprises contacting said coating on said substrate with said recessed pattern.
Claim 24
Dependent Claim
32 words
The method of claim 23, wherein said frit containing material comprises a thermoplastic organic carrier, and prior to said contacting, said coating is heated to facilitate forming of said frit containing material.
Claim 25
Dependent Claim
23 words
The method of claim 10, wherein said organic carrier material in said contacting step comprises a mixture of radiation curable and thermoplastic ingredients.
Claim 26
Dependent Claim
17 words
