FLEXIBLE LIGHT GUIDE
First Claim
1. A light guide comprising a first flexible layer and a second flexible layer, each layer having a first major surface and a second major surface, the second major surface of the first flexible layer being in contact with the first major surface of the second flexible layer, the first major surface of the first flexible layer having a plurality of discrete light extractors capable of extracting light propagating in the light guide such that light is extracted uniformly over substantially the entire first major surface of the first flexible layer.

Abstract
A flexible light guide and a display system incorporating same are disclosed. The light guide includes a first flexible layer and a second flexible layer. Each flexible layer has a first major surface and a second major surface. The second major surface of the first flexible layer is in contact with the first major surface of the second flexible layer. The first major surface of the first flexible layer has a plurality of discrete light extractors capable of extracting light propagating in the light guide such that light is extracted uniformly over the entire first major surface of the first flexible layer.
