    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: In one aspect, the invention provides a light control film having an indicium visible at a range of viewing angles. The light control film comprises a light input surface and a light output surface opposite the light input surface. The control film further comprises alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. Each absorptive region has a height and a length, wherein the heights of the absorptive regions corresponding to the indicium are different that the heights of the absorptive regions that surround the absorptive regions corresponding to indicium.
