    摘要: Shaped refractive articles having compound curved surfaces enable a light source to provide substantially uniform illumination of a linear or planar target. The refractive articles can comprise an input edge or face and an output edge or face, the input edge or face having at least one shaped notch or cavity that can at least partially envelop a light source, wherein the notch or cavity has at least two oppositely signed curved portions shaped to provide substantially uniform illumination of a target by the source. The articles can also be optically coupled to and at least partially envelop a light source, and can have an output edge or surface having at least two oppositely signed curved portions shaped to provide substantially uniform illumination of a target region by the source. The shaped articles can be used in, for example, lighting devices, frontlights, backlights and electronic displays.

    摘要: A wedge-shaped light extractor having a light-redirecting surface with a plurality of projections having a riser segment, a plateau segment, and a facet segment, with land segments flanking the projections. The projections improve extraction efficiency, thereby facilitating use of available light from a light source.

    摘要: An illumination system for a reflective display is particularly useful for microdisplays that use reflective displays. The light source and the reflective image display unit are mounted in a coplanar manner, thus permitting the light source and the display unit to be mounted on a single board, or even on a single substrate. The display unit may include a first light source directing light generally along a first axis and a reflective image display unit disposed with an optical axis substantially parallel to the first axis. A reflective polarizing film is disposed to direct light from the first light source to the reflective image light display unit.

    摘要: A cavity diffuses light received from a light source so as to produce a uniform light output. The cavity is formed from a unitary structure having one or more portions that diffusely reflect light within the cavity and another portion that transmits the uniform light output. The cavity is a unitary structure, formed from an optically diffusive material, that defines a diffusing cavity having an access aperture. A portion of the unitary structure defines diffusely reflective walls and another portion of the unitary structure defines a diffusely transmitting screen. A portion of the diffusely reflecting walls has a portion that has a thickness being greater than a thickness of the diffusely transmitting screen. The diffusely reflective walls reflect and mix light within the diffusing cavity. The diffusing cavity may be employed in an illuminated display device, having a light source and an imaging device which imposes an image on light received from the cavity.

    摘要: A backlight assembly for use in a transmissive display system is described. The backlight assembly includes a light source that illuminates a light chamber. A transmissive display is positioned adjacent the light chamber so that light that exits the chamber illuminates the transmissive display. The backlight assembly may include one or more specular reflectors and one or more other optical elements to ensure that the light that exits the light chamber has the desired spatial uniformity, polarization, color, and/or angular distribution
