Abstract: The disclosure describes asymmetric turning films (ATFs) that may be used in conjunction with multiple light sources in a liquid crystal display assembly to provide multiple different characteristic output distributions of light. In some examples, the ATFs include a structured surface defining a plurality of microstructures having two or more faces with each face configured to reflect light in different directions. The microstructure may define a microstructure axis and an angle gradient characterizing the rotation of the microstructure axis across the structured surface of the ATF.

Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, an absorptive layer or reflective layer is disposed between the alternating transmissive regions and absorptive regions and the light input surface and/or light output surface. In another embodiment, the alternating transmissive regions comprise an absorptive material. The light control film can exhibit low transmission of visible light and high transmission of near infrared light. Also described is a light detection system comprising such light control films and a microstructured film.

Abstract: A light redirecting film, a backlight including the light redirecting film, and a display system including the backlight are described. The light redirecting film may be a microstructured film including a plurality of substantially parallel spaced apart structures on a substrate. The backlight includes a plurality of discrete spaced apart light sources configured to illuminate a plurality of non-illumination zones in a display surface in a one-to-one correspondence relationship; and a microstructured film disposed on the plurality of light sources, such that when the display surface is disposed on the microstructured film and the light sources are energized, at least 80% of light emitted by each light source illuminates a corresponding illumination zone in the display surface, and a luminous intensity distribution across the plurality of the illumination zones has an average I and a standard deviation S, where S/I

Abstract: Brightness enhancing films with embedded diffusers are described. More specifically, films including a birefringent substrate, a prismatic layer carried by the substrate having linear prisms, and an embedded structured surface disposed between the substrate and the prismatic layer are disclosed. The embedded structured surface may include closely-packed structures. Processes for producing embedded structured surfaces having particular topographies are also disclosed.

Abstract: Optical films for redirecting light are described, and optical systems, such as display systems, incorporating such optical films are described. The optical film may include a first structured surface including a plurality of prismatic structures, and a second structured surface opposing the first structured surface and including a plurality of microstructures. An effective transmission of the optical film is not more than 1% less than a film with a comparable construction except for a smooth, non-structured second surface.
