Uniform curved surface structure of a brightness unit for a brightness enhancement film
First Claim
Patent Images
1. A brightness enhancement film having a uniform curved surface structure, comprising:
- a waved film including a top surface and a bottom surface through which penetrating light that is refracted;
a plurality of brightness units arranged on the top surface of the waved film to form an array, each of the brightness units able to refract light in two dimensions for condensing light; and
a plurality of curved bottom edges located at a bottom portion of each of the brightness units so that an adjacent surface to the curved bottom edge formed with a uniform curved surface that has an adequate curvature to generate a two-dimensional retraction with respect to the top surface of the wave film.

Abstract
A brightness enhancement film includes a top surface, a bottom surface and a plurality of brightness units arranged to form an array on the top surface. The brightness unit is consisted of a first cured surface and a second curved surface. Each of the first cured surface and the second curved surface is extended downward to terminate at a curved bottom edge so as to form a uniform curvature of the curved surface.
