摘要： A light guide (14) including a light guide body having a light re-directing side (22) positioned opposite from a light output side (20). 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 (14) also includes a plurality of light extraction structures located adjacent the light re-directing side (22) of the light guide body for reflecting light toward the light output side (20). The light extraction structures include elongated projections (50) each having a plateau segment (54) and first and second facets (56, 58). The elongated projections (50) are separated by lands (52) that are recessed relative to the plateau segments (54). The first and second facets (56, 58) extend from the plateau segments (54) to the lands (52).

摘要： An optical element, such as a lightguide or an optical film, is formed with a predetermined, programmed pattern of optical structures. The optical structures may be arranged to selectively correct for non-uniformities in the output of a lightguide, or may be arranged to otherwise enhance the performance of a display.

摘要： An optical turning film has a first surface including an array of prisms. The array has a plurality of first prisms, with each of the first prisms having a first prism configuration, and a plurality of second prisms, with each of the second prisms having a second prism configuration different from the first prism configuration. The optical film also has a second surface opposing the first surface, and light rays incident to the first surface are directed by the plurality of first prisms and the plurality of second prisms along a direction substantially parallel to a viewing axis.

摘要： A cutting tool assembly having a tool post capable of lateral movement along a work piece to be cut and a shank on the tool post holding at least one machined tool tip and possibly other tool tips. The tool tip has diffractive features in contact with the work piece in order to machine macro-scale features having nano-scale features. The machined work piece can be used to make articles having diffractive features such as optical films having lenslets.

摘要： A backlight includes a lightguide (16), a light source (12) disposed with respect to the lightguide (16) to introduce light into the lightguide (16) and a turning film. Optical structures (40) are formed in one of an output surface (18) and a back surface (20) of the lightguide (16). The optical structures (40) are arranged to extract light from the lightguide (16). A back reflector (24) is disposed adjacent the back surface (20). The optical structures (40) are formed to include a varying pattern arranged to mask non-uniformities in the output of the lightguide (16).

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).
