    Abstract: Various embodiments of an optical construction and an electronic device that includes such optical construction are disclosed. The optical construction includes a lens film having an outermost structured first major surface and an opposing outermost substantially planar second major surface. The structured first major surface includes a plurality of microlenses. The optical construction also includes a mask disposed adjacent to the second major surface of the lens film and includes a plurality of laser-ablated openings disposed through the mask. The openings are aligned to the microlenses in a one-to-one correspondence. The mask further includes a UV-cured polymer material and an optically absorptive material.

    Abstract: An optical construction includes a lens film having outermost first and second major surfaces. The first major surface includes a plurality of microlenses. A multilayer mask having an average thickness of less than about 0.5 times an average focal length of the microlenses and an optical density of greater than about 2 is disposed on the second major surface. The multilayer mask includes polymeric first and second mask layers where each of the first and second mask layers has an optical density of greater than about 0.3. The multilayer mask defines a plurality of laser-ablated through openings therein that are aligned to the microlenses in a one-to-one correspondence. An optical transmittance of the optical construction as a function of the incident angle has a transmitted peak having a peak transmittance T1 and a corresponding full width at 20 percent of maximum W1, where T1/W1≥2.4%/degree.
