Abstract
An illuminated display is disclosed which allows characters to be displayed with near type-set like appearance. This is accomplished by using an appropriately formed and placed rib to connect the optically opaque inner member with the optically opaque base.
Claims17
A display comprising:
- an optically opaque base comprising first and second surfaces, said optically opaque base comprising an aperture, said aperture defining an outer perimeter of a display element;
- a rib attached to said base and disposed within said aperture such that said rib is recessed with respect to said first and second surfaces of said base;
- an optically opaque inner member defining an inner perimeter of said display element, said inner member disposed in said aperture to define a region between said outer and inner perimeters of said display element, said inner member attached to said rib;
- and
- a light source disposed to project light toward said inner member and said base such that light passes through said region.

A display comprising:
- an optically opaque base comprising first and second surfaces, said optically opaque base comprising an aperture therethrough, said aperture defining an outer perimeter of a display element;
- a sculpted rib attached to said base and disposed within said aperture such that said sculpted rib is recessed with respect to said first surface and said second surface of said base;
- an optically opaque inner member defining an inner perimeter of said display element, said inner member disposed in said aperture to define a region between said outer and inner perimeters of said display element, said inner member attached to said sculpted rib;
- and
- a light source disposed to project light toward said inner member and said base such that light passes through said region.

A display comprising:
- an optically opaque base comprising first and second surfaces, said optically opaque base comprising a plurality of apertures therethrough, each said aperture defining an alphanumeric character, said alphanumeric characters being arranged in a sequence having a defined meaning, at least one of said apertures defining a closed alphanumeric character that encloses an optically opaque inner member comprising a third surface substantially coplanar with said first surface of said base and a fourth surface substantially coplanar with said second surface of said base;
- a sculpted rib disposed within said aperture defining said closed alphanumeric character such that said sculpted rib is recessed with respect to said first surface and said second surface of said base, said sculpted rib connecting said inner member to said base such that said inner member is kept in fixed relation to said base;
- and
- a light source disposed to project light toward said base such that light passes through said plurality of apertures to illuminate said sequence.
