Abstract
An electroluminescent display device is increased in size by securing plural small-size panels, each incorporating plural electroluminescent elements, to a large-size support with an intervening adhesive layer.
Claims41
An electroluminescent display device including:
- plural small-size panels each incorporating plural electroluminescent elements on a substrate;
- and
- a large-size support to which said plural small-size panels are secured on surfaces of respective ones of said electroluminescent elements by an intervening adhesive layer.
An electroluminescent display device including:
- plural small-size panels each respectively incorporating plural electroluminescent elements on a single small-size substrate, without a second small-size substrate sandwiching said electroluminescent elements relative to said single small-size substrate;
- and
- a large-size support to which said single small-size substrate of each said small-size panel is secured by an intervening adhesive layer.
An electroluminescent display device comprising:
- plural individual panels that each respectively include an individual substrate and plural electroluminescent elements mounted on a mounting surface of said individual substrate;
- a single continuous support having an area size larger than a single one of said individual panels;
- and
- an adhesive;
- wherein:
- said plural individual panels are arranged with said individual substrates thereof oriented coplanar to each other and parallel to said single continuous support, with said mounting surface of said individual substrate of each of said individual panels facing toward said single continuous support, and with said electroluminescent elements of each of said individual panels received in a space directly between said single continuous support and said mounting surface of said individual substrate of each of said individual panels;
- said adhesive directly contacts said single continuous support and said individual substrate of each one of said individual panels, and spans said space between said single continuous support and said mounting surface of said individual substrate of each one of said individual panels, so that said adhesive thereby adhesively bonds said plural individual panels to said single continuous support and seals said space to seal said electroluminescent elements between said individual substrates and said single continuous support;
- and
- said display device is a unitary sealed unit with said individual substrates of said individual panels forming a first outer side thereof, said single continuous support forming a second outer side thereof opposite said first outer side, and said adhesive sealing edges thereof that span between said first and second outer sides.
