摘要： Lightguides are disclosed. More particularly, lightguides that include a lightguiding layer and a light extracting layer having a structured surface are disclosed. The light guiding layer is optically coupled to a first set of structures of the structured surface at given locations, and is not optically coupled to a second set of structures at given locations, thereby producing total internal reflection at the second locations. The selective optical coupling may be achieved by a number of different contemplated means as discussed herein. The lightguides allow for distribution of light along with redirection towards an image viewer without a number of commonly required optical elements in backlights.

摘要： A method for cutting a pattern in a work piece (50), wherein the pattern includes adjacent features (52,53) separated by a pitch spacing P. The method includes providing a cutting tool assembly (74) having a first tool shank with a first cutting tip (22) to create a first feature (52) in the work piece (50) and a second tool shank with a second cutting tip (23) to create a second feature (53) in the work piece (50), wherein a distance Y between the first cutting tip and the second cutting tip is equal to nP, and wherein n is an odd integer greater than 1. The work piece is rotated (C) with respect to the cutting tool assembly (74), and the cutting tool is advanced along a lateral direction (B) with respect to the rotating work piece (50), wherein the cutting tool (74) is advanced along the lateral direction a distance of 2P for each rotation of the work piece (50).
