Abstract

A film for a screen has a light transmitting substrate and a plurality of structures disposed on the substrate. An optical material at least partially fills cavities between the structures. A method of forming a film includes providing a light transmitting substrate having a plurality of structures disposed thereon and at least partially filling the cavities therebetween with an optical material.

Claims (7)

1. A method of forming a film comprising:

providing a first flexible substrate having opposite first and second major surfaces, the first surface having a plurality of structures;

providing a second flexible substrate having opposite first and second major surfaces; and

laminating the first flexible substrate to the second flexible substrate with an adhesive disposed between the first major surfaces of the first and second flexible substrates, the lamination resulting in a rigid film.

2. The method of claim 1 , wherein the adhesive is a light absorbing adhesive.

3. The method of claim 1 , wherein the plurality of structures define a plurality of cavities therebetween.

4. The method of claim 3 , wherein the adhesive at least partially fills the plurality of cavities.
