Abstract: An electronic device display and a display cover layer may be coupled to a housing. The display may have an array of pixels that are configured to emit light. One or more light redirecting elements may be incorporated into the electronic device that redirect and thereby change the direction of light rays emitted from peripheral pixels in the display. The light redirecting elements may be used to enlarge the effective size of the display, to create images on sidewall surfaces of the display cover layer, and/or to create diffuse glowing areas around the periphery of the device. Light redirecting elements may be formed as integral portions of a display cover layer, as laminated optical films on a display cover layer, or as coating layers on a display cover layer. Afocal optical systems may be formed by placing first and second light redirecting elements on opposing first and second sides of a display cover layer.

Abstract: An optical power prism that may be used in folded lens systems that consists of a glass prism and a glass lens attached to a surface of the prism using a thin layer of optical glue or by optical contact. The glass lens does not have a flange and thus the prism can be smaller than prisms used in conventional power prisms with the same lens effective area, thus reducing the Z-height of the power prism when compared to conventional power prisms. An optical glass may be used for the lens that has a higher refractive index than can be provided by optical plastic which allows the lens to be thinner than plastic lenses. The lenses may be formed by molding a glass wafer to form lens shapes on a first surface of the wafer; the molded wafer is then ground from a second surface to singulate the lenses.
