Apple gains patent for embedding sapphire displays into LiquidMetal chassis73
Although the title and the abstract of the filing use general terms, it does later call out sapphire glass and LiquidMetal by name. The patent essentially calls for metal in liquid form to be injection molded around a piece of glass in order to form the bond. In practical terms, this means that the glass display of your iPhone wouldn't simply be glued onto the digitizer assembly, it would be baked in to the chassis itself. Theoretically, this method would result in a more seamless transition from glass to metal, and could make the device feel nicer in the hand.
isn't even as good a choice as Gorilla Glass in many ways (though Corning is a bit biased).It could also make it impossible to fix your iPhone yourself, especially if Apple moves to a unibody design. It has actually gotten easier to fix a cracked display on a newer iPhone compared to the models from a few years ago, but a build design like this would essentially require a trip to the Apple Store. Sapphire glass is strong, but it is not unbreakable, and Corning would say that it
Of course, despite repeated rumors of LiquidMetal on the way, there is no indication that Apple will be using the material in an iPhone anytime in the near future. So, this patent is still quite a way off from becoming reality anyway.
