Abstract: A light control layer includes alternating transmissive and absorptive regions, along one or two dimensions. The light control layer may be substantially transparent, or have high transmission, for light incident at or near a normal angle to its surface, while absorbing light incident at angles away from normal. The height of the absorptive region, defined orthogonal to the local display surface, may be much greater than the width of the absorptive region resulting in a high aspect ratio structure. The width of the absorptive region may be relatively thin compared to the width of a pixel in a display. The light control layer may be applied to a display or incorporated into a display. The light control layer may be part of a film stack including other functional layers that cooperatively provide desirable optical properties.

CPC classification number: H10K59/879 , G02B3/08
Abstract: An optical system includes an optical film curved about a first axis and a light control film curved about the first axis. The light control film can be disposed between a light source and the optical film. The optical film includes a microstructured first major surface and an opposing second major surface. The microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending longitudinally along the first axis. The first major surface of the optical film faces the light control film. The light control film can include a plurality of alternating optically transmissive and optically absorptive regions extending longitudinally along the first axis such that in a cross-section orthogonal to the first axis, for at least a majority of the optically transmissive regions, a centerline between adjacent optically absorptive regions is substantially normal to a major surface of the light control film.

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.
