Abstract: Film articles with dual-sided structures are ones in which both of the major surfaces of the film have a structured surface. The structured film articles have a first major surface and second major surface, where each surface has a plurality of spaced apart protrusions forming a repeating pattern. Each repeating pattern has a major axis, where the major axis is one of the major axes in the translational direction of the repeating pattern. The major axis of the repeating pattern on the second major surface forms an oblique angle with the major axis on the first major surface, where the angle is in the range of 10-90% of the angle of rotational symmetry of the repeating pattern. The structured film is a unitary substrate. The structured film articles are prepared by providing a flowable material composition having two major surfaces and simultaneously contacting the major surfaces with a first microstructuring tool, and a second microstructuring tool. Each microstructuring tool has a structured surface including a pattern of a plurality of depressions.

Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between a light input surface and a light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, the alternating transmissive regions and absorptive regions have a transmission as measured with a spectrophotometer at a viewing angle of 0 degrees of at least 35, 40, 45, or 50% for a wavelength of the range 320-400 nm (UV) and/or at least 65, 70, 75, or 80% for a wavelength of the range 700-1400 nm (NIR). In another embodiment, the absorptive regions block light at the light input surface and light output surface and the maximum surface area that is blocked is less than 20% of the total alternating transmissive regions and absorptive regions. Also described are various optical communication systems comprising the light control films described herein and methods.

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.

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.
