Abstract: The disclosed computer-implemented method may include coupling an array of reflective polarizers to a back surface of a back optical substrate; coupling an array of quarter-wave plates to a front surface of the back optical substrate such that the array of quarter-wave plates is aligned with the array of reflective polarizers; molding the back optical substrate with at least one initial mold, wherein the at least one initial mold defines an initial array of optical element surfaces that is aligned with the array of quarter-wave plates; and twin-sheet thermoforming, between a front twin-sheet mold and a back twin-sheet mold, the back optical substrate with a front optical substrate, wherein the front twin-sheet mold defines a front array of optical element surfaces and the back mold defines a back array of optical element surfaces. Various other methods, apparatuses, and systems are also disclosed.

Abstract: Multilayered interlayers having improved acoustic properties comprising a stiff skin layer(s) and a soft core layer comprising EVA are disclosed. The multilayered interlayers comprise: a first polymer layer (skin layer); a second polymer layer (skin layer); and a third polymer layer (core layer) comprising ethylene vinyl acetate resin between the first polymer layer and the second polymer layer.
