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: An optical film assembly comprises a light redirecting film (110) having a first structured major surface (112) and a second, opposed major surface (114). An optical adhesive layer (120) is disposed on the second major surface of the light redirecting film. A light diffusion film (140) comprises a first major surface (142) comprising a light diffusion surface and a second, opposed major surface (144). A plurality of discrete optical decoupling structures (146) project from the light diffusion surface and contact the optical adhesive layer. An air gap (148) is defined between the first major surface of the light diffusion film and the optical adhesive layer. Embodiments of optical film assemblies described herein are useful, for example, for hiding optical defects and improving the brightness uniformity of light emitted by a light source.

Abstract: An optical construction includes a lens film having opposing first and second major surfaces. The first major surface includes a plurality of microlenses arranged along orthogonal directions. An optically opaque mask layer including a UV-cured polymer material is disposed on the second major surface of the lens film and defines a plurality of laser-ablated through openings therein. The openings are aligned to the microlenses in a one-to-one correspondence. For a substantially collimated light incident on the first major surface along an incident direction, an optical transmittance of the optical construction as a function of a transmitted angle includes a first transmitted peak having a first transmittance T1 at a first transmitted angle within about 10 degrees of the incident direction, and a second transmitted peak having a second transmittance T2 at a second transmitted angle between about 30 to 60 degrees of the incident direction, wherein T2/T1 ≥ 0.01.

Abstract: An optical light redirecting film that can be made by microreplication, and that is suitable for use in an autostereoscopic backlight or display, includes opposed first and second structured surfaces. The first structured surface includes lenticular features and the second structured surface includes prismatic features. In some cases, at least a first prismatic feature has a first prism optical axis that is tilted relative to a thickness axis of the film perpendicular to the film plane. In some cases, at least a first lenticular feature has a first lenticular optical axis that is tilted relative to the thickness axis. In some cases, the film may have a central film caliper (thickness) at a central portion of the film and an edge film caliper at a first edge portion of the film, the central film caliper being greater than the edge film caliper.
