BRIGHTNESS ENHANCEMENT FILM HAVING A LIGHT-GUIDING STRUCTURE
First Claim
1. A brightness enhancement film having a light-guiding structure comprising:
- a substrate having a light incident surface and a light emission surface, the substrate made from a first transparent material which permits penetrating light through the substrate;
a light-refracting layer arranged on the light incident surface of the substrate, the light-refracting layer providing changes in curvature so as to refract the light projecting from a light source; and
a light-guiding layer formed between the light incident surface and the light emission surface of the substrate so as to guide the refracted light transmitting from the light incident surface to the light emission surface.

Abstract
A brightness enhancement film having a light-guiding structure includes a substrate, which has a light-guiding layer and a plurality of light-refracting microstructures. The substrate has a light incident surface and a light emission surface opposite thereto. The light-refracting microstructures are arranged on the light incident surface of the substrate, and provided for varying surface curvatures to refract incident light. The light-guiding layer is arranged on the light emission surface of the substrate, and provided for guiding refracted light to generate homogeneous light to emit therefrom.
