    Abstract: An optical film assembly comprising a first optical film, a coupling member, and a second optical film wherein the first optical film comprises a prismatic film, the second optical film comprises a diffuser, wherein the coupling member is bonded to the first optical film and to the second optical film such that the first optical film and second optical film are physically coupled, and the coupling member is bonded to at least one of the first optical film and the second optical film non-continuously such that an optically effective air gap is provided. Also, a method for making such optical film assemblies.

    Abstract: An optical construction includes a lens film having an outermost structured first major surface and an opposing outermost substantially planar second major surface. The first major surface includes a plurality of microlenses. A radiation cured optically opaque mask layer is disposed on the second major surface of the lens film. The mask layer has an average thickness of less than about 10 microns and defines a plurality of laser-ablated through openings therein. The through openings are aligned to the microlenses in a one-to-one correspondence, such that for a light incident on the structured first major surface along an incident direction forming an incident angle with the second major surface, an optical transmittance of the optical construction as a function of a transmitted angle includes a first transmitted peak having a first peak transmittance T1≥40%. The first transmitted peak can be within about 10 degrees of the incident angle.

    Abstract: An optical system includes a lens layer including a plurality of microlenses arranged along orthogonal first and second directions, and at least one optically opaque mask layer spaced apart from the lens layer and defining a plurality of through openings therein arranged along the first and second directions. There is a one-to-one correspondence between the microlenses and the openings, such that for each microlens, the microlens and corresponding openings are substantially centered on a straight line making a same oblique angle with the lens layer. An optical layer can include the lens layer and the optically opaque mask layer embedded in the optical layer.

    Abstract: An optical system is disclosed and includes an image sensor (112), a plurality of microlenses (142), at least one microlens of the plurality of microlenses defining a microlens height and a microlens diameter. The optical system also includes a plurality of light-blocking structures (146), at least one light-blocking structure of the plurality of light-blocking structures defining a light-blocking structure height and a light-blocking structure width. An aperture array (134) includes a plurality of apertures (138), each aperture being aligned with a microlens of the plurality of microlenses, and the microlenses and the light-blocking structures extend from the aperture array toward the image sensor. The systems, structures and features disclosed herein can improve a signal-to-noise ratio when detecting images, via the optical sensor, from behind a display.
