Abstract
Abstract In a method for manufacturing a display, a substrate having a surface on which a plurality of light-emitting diodes are aligned is disposed such that the surface opposes a surface of a table. A resin of a light-emitting and electrically insulating material which is kept in a fluid state is filled by capillarity into a space defined by the surface of the substrate and the surface of the table. The resin is then hardened, and the table is removed from a hardened resin. A display is obtained wherein at least the space between the adjacent LEDs is filled with the hardened resin.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
127 words
A method for manufacturing a display device, comprising the steps of: disposing a substrate having a surface on which a plurality of light-emitting diodes are two-dimensionally aligned such that said surface of said substrate opposes a surface of a table which is substantially horizontal; placing a resin of a light-transmitting and electrically insulating material which is kept in a fluid state on said table so as to bring said resin into contact with at least one side end of said substrate; filling by capillarity said resin into a space between said surface of said table and said surface of said substrate while said resin is kept in the fluid state; hardening said resin which is filled in said space; and removing said table from a hardened resin.
Claim 2
Independent Claim
127 words
A method for manufacturing a display device, comprising the steps of: disposing a substrate having a surface on which a plurality of light-emitting diodes are two-dimensionally aligned such that said surface of said substrate opposes a surface of a table which is substantially horizontal; placing a resin of a light-transmitting and electrically insulating material which is kept in a fluid state on said table so as to bring said resin into contact with at least one side end of said substrate; filling by capillarity said resin into a space between said surface of said table and said surface of said substrate while said resin is kept in the fluid state; hardening said resin which is filled in said space; and removing said table from a hardened resin.
Claim 3
Dependent Claim
27 words
A method according to claim 1, wherein said space between said surface of said substrate and said surface of said table is not more than 1.0 mm.
Claim 4
Dependent Claim
22 words
A method according to claim 1, wherein said table is made of a material which does not adhere to said hardened resin.
Claim 5
Dependent Claim
30 words
A method according to claim 1, wherein said surface of said table is coated with a material which does not adhere to said hardened resin and is readily separated therefrom.
Claim 6
Independent Claim
33 words
A method according to any one of claims 1 to 4, wherein said plurality of light-emitting diodes respectively have electrical conductors, and said substrate is supported on said table through said electrical conductor.
Claim 7
Independent Claim
24 words
A method according to any one of claims 1 to 4, wherein said plurality of light-emitting diodes are in direct contact with said table.
Claim 8
Dependent Claim
25 words

Claim 9
Dependent Claim
26 words
A method according to claim 7, wherein said tape has an adhesive layer on a surface thereof, said adhesive layer opposing said surface of said substrate.
Claim 10
Dependent Claim
24 words
A method according to claim 8, wherein said tape is made of a material which does not disperse light rays emitted from said diodes.
Claim 11
Dependent Claim
11 words
A method according to claim 8, wherein said tape is colored.
Claim 12
Dependent Claim

Independent Claim
24 words
A method according to any one of claims 7 to 11, wherein said plurality of light-emitting diodes are in direct contact with said tape.
Claim 15
Dependent Claim
52 words
A method according to claim 1, wherein a tape which has an adhesive layer on a surface thereof is adhered on said surface of said table, and a plate of a light-transmitting and electrically insulating material is adhered on said adhesive layer of said tape and opposes said surface of said substrate.
Claim 16
Dependent Claim
17 words
A method according to claim 14, wherein said plate is made of glass or a synthetic resin.
Claim 17
Dependent Claim
13 words

Claim 18
Independent Claim
33 words
A method according to any one of claims 14 to 16, wherein said plurality of light-emitting diodes respectively have electrical conductors, and said substrate is supported on said plate through said electrical conductors.
Claim 19
Independent Claim
24 words
A method according to any one of claims 14 to 16, wherein said plurality of light-emitting diodes are in direct contact with said plate.
