    摘要： Lightguides are disclosed. More particularly, lightguides that include a lightguiding layer and a light extracting layer having a structured surface are disclosed. The light guiding layer is optically coupled to a first set of structures of the structured surface at given locations, and is not optically coupled to a second set of structures at given locations, thereby producing total internal reflection at the second locations. The selective optical coupling may be achieved by a number of different contemplated means as discussed herein. The lightguides allow for distribution of light along with redirection towards an image viewer without a number of commonly required optical elements in backlights.

    摘要： A frontlit touch panel for use with a reflective light valve, comprising a front light guide having at least one light input face that supplies light to the guide, a viewing face, a light output face opposite the viewing face, and at least one component of a touch-sensitive transducer, the light output face having a light extraction layer thereon having a substantially flat light exit face and containing buried reflective facets that extract supplied light from the guide through the light exit face. The touch panel can be used with a light source, reflective light valve and suitable control electronics to form a compact, efficient illuminated touch panel display assembly.

    摘要： In one aspect, the invention provides a light control film having an indicium visible at a range of viewing angles. The light control film comprises a light input surface and a light output surface opposite the light input surface. The control film further comprises alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. Each absorptive region has a height and a length, wherein the heights of the absorptive regions corresponding to the indicium are different that the heights of the absorptive regions that surround the absorptive regions corresponding to indicium.

    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.
