    CPC classification number: G02B5/3083

    Abstract: An article for use in light spreading includes a body having first and second surfaces, and first and second in-plane axes that are orthogonal with respect to each other and a third axis that is mutually orthogonal to the first and second in-plane axes in a thickness direction of the body. A portion of the first surface is a birefringent structured surface. The portion is structured such that, when the article receives a light signal within a particular range of wavelengths, the structured surface causes splitting the light signal into a plurality of divergent light signals. The article can be used for color mixing such as in a cavity providing a backlight for LCD devices or other display devices requiring a backlight.

    Abstract: The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes at least one curved portion and a remote light source. The delivery and distribution system (i.e., light duct, redistribution plate, and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct.

    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 daylight-coupled display includes a plurality of passive backlights cascaded in a stack for backlighting of LCD panels or static display panels. The display includes a diffuser to transmit light to multiple cascaded curved reflectors, each of which reflects light for backlighting of the display. A polarization rotator is located within the backlight such that the reflectors provide the correct polarization of light to the LCD panel for backlighting of it. One daylight-coupled display can include an active light source to provide light to the reflectors. A secondary light source can provide light to at least one of the reflectors to provide backlighting of the display in low lighting conditions.
