Abstract
An optical construction includes a lens film having a plurality of optically transparent first beads at least partially embedded in a first layer. A light blocking second layer is disposed on the lens film and defines a plurality of through openings therein extending at least partially between opposite major top and bottom surfaces of the second layer. The through openings are aligned to the first beads in a one-to-one correspondence.
Claims3
An optical construction comprising:
- a first layer comprising a plurality of optically transparent first beads at least partially embedded therein,
- bottom-most portions of the first beads disposed at, or proximate to, a major bottom surface, opposite a major top surface, of the first layer, the bottom-most portions of the first beads and the major bottom surface defining a plurality of contact or near contact regions therebetween;
- and
- a light blocking second layer disposed on the major bottom surface side of the first layer and defining a plurality of through openings therein extending between opposite major top and bottom surfaces of the second layer, the through openings aligned to the contact or near contact regions in a one-to-one correspondence.
