    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.

    Abstract: Display devices that include: an organic light emitting diode panel having a multilayer construction including one or more adhesive films; and a polymeric film incorporated within the multilayer construction of the organic light emitting diode panel. The polymeric film includes: a first polymeric layer having two major surfaces, wherein the first polymeric layer includes: a first polymer region including a first material having a refractive index of n1; a second region including a network of interconnected pores and channels within the first polymer region; wherein the pores and channels comprise a second material having a refractive index of n2; wherein n1 is different than n2; wherein the first material includes a first elastic polymeric material and optional particles; and wherein the second material includes: a second polymeric material and optional particles; and/or air; and wherein the polymeric film has: a clarity of at least 90%; a visible light transmission of at least 80%; and a bulk haze of 25% to 80%.

    Abstract: A structured optical surface and an optical imaging system including the structured optical surface is described. The structured optical surface includes a plurality of structures formed by an intersection of at least first and second Fresnel patterns, such that when the structured optical surface is incorporated in an optical imaging system comprising a pixelated display surface with at least one pixel comprising at least two sub-pixels spaced apart by a gap, the structured optical surface images the at least two sub-pixels onto an image surface as at least two corresponding imaged sub-pixels spaced apart by a corresponding imaged gap, and the structured optical surface diffracts light so that the diffracted light at least partially fills the imaged gap without substantially overlapping any of the at least two imaged sub-pixels.
