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： Polymer fibers are formed with concentric alternating layers of different polymer materials. The layers pairs have cross-sectional thicknesses selected for reflecting light at a selected visible wavelength. A cross-sectional dimension of the core is at least ten times an average of the selected thicknesses of the alternating layers. Some articles formed by the fibers are formed by attaching one fiber to another: the color of the fibers at the point of attachment is different from the colors of the fibers elsewhere. The fibers may be deformed to change its color properties by elongating the cross-section of the polymer fiber along a first cross-sectional axis. In some embodiments, the fibers are polarization sensitive.

摘要： A light with integrated light and thermal guides, and having solid state light sources such as LEDs. The light guide includes a material having a first surface and a second surface opposite the first surface and forming an interior volume. The light guide is coupled to the LEDs for receiving and distributing light from them through the first surface, and the light is transported through the light guide until the light is extracted from the first or second surface. The light guide can include alignment features such as fiducials that mate with a base. The thermal guide is contained within the interior volume and integrated with the light guide for providing thermal conduction from the LEDs for cooling the light. The thermal guide can be vented to provide for internal cross flow of air for the cooling.

摘要： A scanning backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide formed from a plurality of segments. Each segment has a first side and a second side opposite the first side, and a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. The plurality of segments are arranged substantially in parallel and with the second surfaces transmitting light in substantially the same direction to provide backlighting for a stereoscopic 3D liquid crystal display. A first light source is disposed along the first side of each segment for transmitting light into the light guide from the first side, and a second light source is disposed along the second side of each segment for transmitting light into the light guide from the second side. Each segment first and second light source is selectively turned on and off in a particular pattern and each segment light source selectively transmits light into the light guide first side or light guide second side to form a scanning backlight.

摘要： 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.
