iphoneA recently uncovered patent suggests that Apple (NASDAQ:AAPL) may be considering using an alternative material for its future device displays, reports Apple Insider. Apple currently uses Corning’s (NYSE:GLW) Gorilla Glass as the primary covering material for the iPhone and iPad displays.

However, in a patent titled “Sapphire Laminates,” Apple outlines a method for mass-producing displays made from this gemstone material that is almost as hard as diamond. One embodiment describes a method for fusing sapphire sheets together in order to create an electronic device display or display cover.

Other embodiments outlined in the patent describe methods for fusing sapphire sheets to chemically-strengthened glass sheets. Still, other embodiments describe methods for fusing two sapphire sheets with “different crystal orientations” together in order to take advantage of the different characteristics found in different sapphire planes.
