Differentially-cured materials and process for forming same
First Claim
1. A light-collimating optical structure comprising a first side and a second side, the first side including an array of light-collimating prisms formed of a radiation-cured composition, wherein the array of light-collimating prisms includes a first portion and a second portion, the first portion has a first index of refraction and the second portion has a second index of refraction, the first portion and the second portion are both formed of the radiation-cured composition, and the first index of refraction is different from the second index of refraction.

Abstract
A light-redirecting optical structure includes a first side and a second side, the first side including plurality of linear prisms having a visibly random shaped surface on the prisms and a plurality of cross-cut prisms on first side which are oriented at an angle such that it is greater than zero degrees but less than 180 degrees. A backlight wedge includes a stepped structure on a bottom side that decreases in size traversing the wedge away from a light source which is positioned at an end and having a visibly random shaped surface on said wedge.
