Abstract: Optical systems are disclosed. More particularly, optical systems including an asymmetric turning film (110) with at least a first (120) and second light source (130) are disclosed. Selection of geometries for the asymmetric turning film can enable different output viewing angles depending on the selective illumination of the first light source, the second light source, or both. The optical systems disclosed may be suitable in both luminaires and displays.

Abstract: This application describes a back- lit transmissive display including a transmissive display ( 620 ) and a variable index light extraction layer ( 640 ) optically coupled to a lightguide ( 630 ). The variable index light extraction layer has first regions ( 140 ) of nanovoided polymeric material and second regions ( 130 ) of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.
