Abstract: A recycling cavity such as used in a backlight or similar extended area source includes a front and back reflector, the front reflector being partially transmissive to provide an output illumination area. The recycling cavity also includes a component that provides the cavity with a balance of specular and diffuse characteristics so as to balance cavity efficiency and brightness uniformity over the output area. The component can be characterized by a transport ratio of greater than 15% for a 15 degree incidence angle, and less than 95% for a 45 degree incidence angle.

Abstract: A system for on-product projection and display of electronic content. The system includes a projector for projecting electronic content, a mirror film stack having a reflective surface facing the projector, and a product having an exterior surface facing the reflective surface of the mirror film stack. A graphic is located on a surface of the mirror film stack opposite the reflective surface. The electronic content from the projector is projected onto the exterior surface of the product via the reflective surface of the mirror film stack. The graphic can be located on a display window and hide the mirror from a viewer without completely blocking a view of the projected electronic content. The product can include a removable projection screen for displaying the electronic content, and the projection screen can include a removable label on its non-viewer side to advertise or promote the product.

Abstract: A detector system is described that includes a detector that is sensitive to wavelengths in a detection wavelength range. The detector system further includes a light control film that is disposed on the detector and includes a plurality of alternating first and second regions. Each first region has a width W and a height H, where H/W≥1. Each first region has a substantially low transmission in a first portion of the detection wavelength range and a substantially high transmission in the remaining portion of the detection wavelength range. Each second region has a substantially high transmission in the detection wavelength range.

Abstract: A retroreflective system is disclosed that includes a retroreflective sheet for retroreflecting light, and a light control film disposed on the retroreflective sheet. For a first wavelength, light incident on the light control film at each of a first and second angles of incidence is retroreflected.

Abstract: A multilayer optical film has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film. Heating element(s) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered region(s) of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered region(s) to pattern the film. The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered region(s), while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered region(s).
