    摘要： Collimating light engines, methods of making collimating light engines, and articles incorporating collimating light engines are disclosed. In one aspect, a light source and circuitry can be disposed between a reflector and a reflective baffle to form a collimating light engine. The light source is at least partially obscured from view by the reflective baffle. Light emitted from the light source is partially collimated upon leaving the light engine. Light uniformity of the output surface of a backlight can be proved by disposing an array of the collimating light engines in the backlight

    摘要： An 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.

    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 electrical connector assembly having an interleaved multilayer structure includes a first connector structure having at least a first connector layer, and a second connector structure having at least second and third connector layers. A plurality of conductive contact surfaces are disposed along edge portions of the connector layers. Upon engagement of the first connector structure and the second connector structure, the first connector layer is oriented to engage a gap defined between the second and third connector layers. The interleaved engagement of the connector layers results in an low-profile electrical connector assembly providing a large number of interconnections between respectively aligned contact surfaces with precise alignment and reliable electrical contact. The connector layers may include conductive contact surfaces on one or both sides of each layer to provide higher interconnection densities. The disposition of contact surfaces on both sides of a layer can relax alignment tolerances for a given interconnection density. Nevertheless, precise alignment can be ensured by the use of conventional lithographic techniques to print the contact surfaces. At least some of the connector layers can be made from a material capable of resilient deformation, and can be realized, for example, by flexible printed circuit board layers or flex circuit layers. The resiliently deformable material, when deformed, produces a force that resists deformation. Thus, when interleaved engagement of the connector layers produces deformation, the resisting force serves to bias the connector layers against one another to ensure good electrical contact force.
