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: 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 nano structured 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 nano structured 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 nano structured bilayer.
