Integrated low profile display
First Claim
1. An integrated low profile display apparatus, comprising:
- a substrate having a first surface and a second surface;
said substrate defining at least one penetration extending through said substrate from said first surface to said second surface;
each said penetration having a side wall, an entrance opening defined by said first surface, and an exit opening defined by said second surface;
at least one light emitting device; and
a light diffuser associated with said exit opening of said penetration;
each said light emitting device mounted to said first surface of said substrate proximate the entrance opening of a corresponding penetration and adapted to selectively admit light to said penetration via said entrance opening; and
each said light emitting device being electrically connected to a corresponding electrical conductor attached to said first surface of said substrate.

Abstract
A panel, such as a component carrier or substrate, is provided with one or more penetrations. A light source associated with a surface of the panel and the corresponding end of each penetration provides light to the interior of the penetration, which guides the light to the other end of the penetration and corresponding surface of the panel. The penetration can be coated with a reflective material to improve its performance as a light guide. Alternatively or additionally, the penetration can be filled with a refractive material. A diffuser can be provided to diffuse light exiting the penetration. The light sources provides light to selected penetrations on demand such that the penetrations function as displays or elements of a display.

29. An integrated low profile display apparatus, comprising:
-
a substrate having a first surface and a second surface; said substrate defining at least one cavity; said cavity having a substantially opaque side wall, an entrance opening defined by said first surface, and a closed end; and at least one light emitting device; each said light emitting device mounted to said first surface of said substrate proximate the entrance opening of a corresponding cavity and adapted to selectively admit light to said cavity via said entrance opening, and each said light emitting device electrically coupled to an electrical conductor attached to said first surface of said substrate. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 57, 58)
