    摘要： A system for projecting content onto a shaped screen. The system includes a projector configured for projecting content having a particular shape and a rear projection screen with an optically active light redirecting film, such as Fresnel lenses, for receiving and displaying the projected content. The rear projection screen and the optically active light redirecting film each have a shape substantially conforming to the particular shape of the content. The optically active light redirecting film, such as a Fresnel lens sheet, provides for brightness uniformity and a wide view angle. The rear projection screen can include a turning film for displaying content received from the projector at an angle.

    摘要： A passive daylight-coupled display having an LCD panel, a diffuser, and a curved reflector behind the LCD panel. For passive backlighting, the diffuser transmits daylight to the reflector, which reflects the daylight to the LCD panel and provides for substantially uniform distribution of the daylight on the LCD panel for backlighting it. An N-stack daylight-coupled display includes a plurality of passive backlights cascaded in a stack for backlighting of LCD panels or static display panels. One N-stack display can include an active light source to provide light to the reflectors, and a secondary light source to provide light to at least one of the reflectors to provide backlighting of the display in low lighting conditions. A collapsible daylight-coupled display includes a daylight-coupled backlight that is collapsible when not in use for hand-held or portable display devices.

    摘要： A stereoscopic 3D liquid crystal display module includes a liquid crystal display panel and a directional backlight positioned to provide light to the liquid crystal display panel. A double sided prism film is disposed between the liquid crystal display panel and the directional backlight. The prism film includes a first surface having a series of cylindrical lenses adjacent the liquid crystal display panel and a second surface, opposite the first surface, having a series of non-contiguous prisms adjacent the directional backlight. Each of the non-contiguous prisms is separated from adjacent prisms by a transmissive flat portion or an opaque portion.

    摘要： An optical low pass filter or blur filter, and method of making the filters, using an article having a birefringent surface for refracting incoming light when used with an image sensor. The birefringent surface of the article, such as a film, is structured or tilted such that, when the blur filter is placed within an optical path between a lens and the image sensor, the birefringent surface causes refraction of a light signal in the optical path into multiple light signals each being incident upon different sub-pixels within the pixels in the image sensor to prevent or reduce artifacts, such as undesirable color moiré effects, in the resulting digital image. The structures on the surface have a variable pitch or angles. The variable pitch can include a periodic, aperiodic, or quasi-aperiodic pitch, to reduce diffractive artifacts in the resulting image.
