Display having thin cross-section and/or multi-colored output
First Claim
1. A display apparatus comprising:
- a first substrate having a first side and a second side;
said first substrate defining a first optical path extending from said first side of said first substrate to said second side of said first substrate; and
a first light source associated with said first side of said first substrate and further associated with said first optical path such that light emitted by said first light source propagates from said light source to said second side of said substrate via said first optical path but not in a single straight line.

Abstract
A display includes a substrate having front and rear sides and defining one or more optical paths. A light source corresponding to each optical path is associated with the rear side of the substrate. Light propagates from the light source to the front side of the substrate through the corresponding optical path. Offsetting the light source from the centerline of the optical path improves light diffusion by promoting light reflection off the sides of the optical path. Multiple light sources of different colors can be associated with each optical path to provide for variable color output from each optical path at the front side of the substrate.

11. A display apparatus comprising:
-
a first substrate having a first side and a second side;
said first substrate defining a first optical path extending from said first side of said first substrate to said second side of said first substrate; and
a first light source associated with said first side of said first substrate such that light emitted by said first light source is visible from said second side of said substrate and such that the majority of said light emitted by said first light source propagates from said light source to said second side of said substrate via said first optical path but not in a single straight line.

12. A display apparatus comprising:
-
a first substrate having a first side;
said first substrate comprising a first optical path extending to said first side of said first substrate; and
a first plurality of light sources associated with said first optical path such that light emitted from a first of said plurality of light sources blends with light emitted from a second of said plurality of light sources and such that the blended light propagates to said first side of said substrate via said first optical path. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
