Abstract

Abstract In a method for manufacturing a display, a substrate (21) having a surface (21a) on which a plurality of light-emitting diodes (23) are aligned is disposed such that the surface (21a) opposes a surface (25a) of a table (25). A resin (26) 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 (21a) of the substrate (21) and the surface (25a) of the table (25). The resin (26) is then hardened, and the table (25) is removed from a hardened resin (25'). A display is obtained wherein at least the space between the adjacent LEDs (23) is filled with the harderred resin (26').

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 172 words
A method for manufacturing a display device wherein a substrate (21) having a surface (21a) on which a plurality of light-emitting diodes (23) are two-dimensionally aligned is prepared, and a hardened resin (26') is formed at least between said plurality of light-emitting diodes (23), characterized in that: said surface (21a) of the substrate (21) opposes a surface (25a) of a table (25) which is substantially horizontal; a resin (26) of a light-transmitting and electrically insulating material which is kept in a fluid state is placed on said table (25) so as to bring said resin (26) into contact with at least one side end of said substrate (21); said resin (26) is filled by capillarity into a space between said surface (25a) of said table (25). and said surface (21a) of said substrate (21) while said resin (26) is kept in the fluid state; said resin (26) which is filled in said space is hardened to form a hardened resin (26'); and said table (25) is removed from said hardened resin (26').
Claim 2
Independent Claim 172 words
A method for manufacturing a display device wherein a substrate (21) having a surface (21a) on which a plurality of light-emitting diodes (23) are two-dimensionally aligned is prepared, and a hardened resin (26') is formed at least between said plurality of light-emitting diodes (23), characterized in that: said surface (21a) of the substrate (21) opposes a surface (25a) of a table (25) which is substantially horizontal; a resin (26) of a light-transmitting and electrically insulating material which is kept in a fluid state is placed on said table (25) so as to bring said resin (26) into contact with at least one side end of said substrate (21); said resin (26) is filled by capillarity into a space between said surface (25a) of said table (25). and said surface (21a) of said substrate (21) while said resin (26) is kept in the fluid state; said resin (26) which is filled in said space is hardened to form a hardened resin (26'); and said table (25) is removed from said hardened resin (26').
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
