    Abstract: An optical metasurface film includes a flexible polymeric film having a first major surface, a patterned polymer layer having a first surface proximate to the first major surface of the flexible polymeric film and having a second nanostructured surface opposite the first surface, and a refractive index contrast layer including a refractive index contrast material adjacent to the nanostructured surface of the patterned polymer layer forming a nanostructured bilayer with a nanostructured interface. The nanostructured bilayer comprising a plurality of nanostructures disposed on the flexible polymeric film. The nanostructured bilayer imparts a light phase shift that varies as a function of position of the nanostructured bilayer on the flexible polymeric film. The light phase shift of the nanostructured bilayer defines a predetermined operative phase profile of the optical metasurface film. A light reflecting layer is in optical communication with the nanostructured bilayer.

    Abstract: An idler roller having a fixed shaft with at least one spherical bearing and a second bearing which may, but need not be, a spherical bearing. In some embodiments, the second bearing is slidably- mounted on a central shaft. A shell is mounted between these bearings. Any changes in dimensions resulting from changes in temperature may them be accommodated by sliding movement of the second bearing, sparing the shell from distortion by bending or buckling. In other exemplary embodiments, the spherical bearing includes a first housing element fixedly-mounted on a central shaft and a complementary first free element disposed against the first housing element. A second bearing element is mounted on the central shaft, and a shell is attached to the first free element and rotatably-mounted to a second bearing element with a biasing element mounted on the central shaft urging a second free element away from the first free element.

    Abstract: A method of applying a pattern to a nonplanar surface. A stamp has a major surface with pattern elements having a lateral dimension of greater than 0 and less than about 5 microns. The major surface of the stamp has a functionalizing molecule with a functional group selected to chemically bind to the nonplanar surface. The stamp is positioned to initiate rolling contact with the nonplanar surface, and contacts the nonplanar surface to form a self-assembled monolayer (SAM) of the functionalizing material thereon and impart the arrangement of pattern elements thereto. The major surface of the stamp is translated with respect to the nonplanar surface such that: a contact pressure is controlled at an interface between the stamping surfaces and the nonplanar surface, and a contact force at the interface is allowed to vary while the stamping surfaces and the nonplanar surface are in contact with each other.

    Abstract: A method of making a reflective tray that is useful in backlight modules for electronic devices comprises (a) providing a reflective tray template comprising a polymeric dielectric multilayer reflector on a compliant pad, the reflective tray template having a first major surface, an opposing major surface, and a reflective tray bottom area having corners; and (b) pressing a blade into the first major surface of the polymeric dielectric multilayer reflector along the perimeter of at least one side of the reflective tray bottom area to form a reflective tray side extending perpendicular to the reflective tray bottom area.

    Abstract: A process including providing a coating head having an external opening in flow communication with a source of a first coating liquid, positioning the coating head relative to a substrate to define a gap between the external opening and the substrate, creating relative motion between the coating head and the substrate in a coating direction, and dispensing a predetermined quantity of the first coating liquid from the external opening onto at least a portion of at least one major surface of the substrate to form a discrete patch of the first coating liquid in a predetermined position on at least a portion of the major surface of the substrate. The first coating liquid as dispensed exhibits a viscosity of at least 1 Pascal-sec. In some exemplary embodiments, the first coating liquid is a liquid optically clear adhesive composition used in a laminate including a light emitting or reflecting device component.
