    摘要： Optical stack is disclosed. The optical stack includes a light redirecting film that includes a first structured major surface that includes a plurality of unitary discrete structures. The optical stack also includes an optical adhesive layer that is disposed on the light directing film. At least portions of at least some unitary discrete structures in the plurality of unitary discrete structures penetrate into the optical adhesive layer. At least portions of at least some unitary discrete structures in the plurality of unitary discrete structures do not penetrate into the optical adhesive layer. The peel strength of the light redirecting film and the optical adhesive layer is greater than about 30 grams/inch. The average effective transmission of the optical stack is not less or is less than by no more than about 10% as compared to an optical stack that has the same construction except that no unitary discrete structure penetrates into the optical adhesive layer.

    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 light guide including a light guide body having a light re-directing side positioned opposite from a light output side. A plurality of elongate prisms are located adjacent the light output side of the light guide body. The prisms extend side-by-side relative to one another along lengths. The prisms include upper edges defining heights of the prisms. The upper edges extend along the lengths of the prisms. Each upper edge includes a plurality of edge segments having different magnitudes of slope. The light guide also includes a plurality of light extraction structures located adjacent the light re-directing side of the light guide body for reflecting light toward the light output side. The light extraction structures include elongated projections each having a plateau segment and first and second facets. The elongated projections are separated by lands that are recessed relative to the plateau segments. The first and second facets extend from the plateau segments to the lands.

    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.
