FILM, BACKLIGHT DISPLAYS, AND METHODS FOR MAKING THE SAME
First Claim
1. A film, comprising:
- a surface comprising a plurality of prism structures, wherein each prism structure has a lateral modulation in the w direction of ±
2% to ±
20% of an average pitch of the prism structures;
wherein the plurality of prism structures have a variation in the w direction of prism peak height that is discrete and/or continuous.

Abstract
In one embodiment a film can comprises a surface comprising a plurality of prism structures. Each prism structure has a lateral modulation in the w direction of less than or equal to ±20% of an average pitch of the prism structures. The plurality of prism structures can have a variation in the w direction of prism peak height that is discrete and/or continuous. In one embodiment, a method for making a film can comprise forming a plurality of prism structures on a surface. The plurality of prism structures can have a lateral modulation in the w direction of less than or equal to ±20% of an average pitch of the prism structures, and wherein the plurality of prism structures have a variation in the w direction of prism peak height that is discrete and/or continuous.

13. A film, comprising:
-
a surface comprising a plurality of prism structures; wherein each prism structure has a lateral modulation in the w direction of ±
2% to ±
15% of an average pitch of the prisms;wherein the plurality of prism structures has a variation in the w direction of prism peak height that is discrete and/or continuous; and wherein with a highest prism peak height is sinusoidal and periodic at an interval measured in the w direction of greater than or equal to five times an average pitch, wherein the average pitch is determined over a sample length in the w direction of 100 mm, wherein the interval w direction is perpendicular to the l direction.
