Apple Patents Sapphire Growing, Harvesting and Cutting Methods for Ultra-Tough Displays

By Gary Cutlack on at

Apple's been queuing up at the patent office again, this time filing a list of various methods of creating and cutting pure lumps of sapphire, for use as extra-strong screens in the new technology of the middle-distant future.

The actual patent uses some slightly opaque language, describing the creation and cutting of "sapphire windows" that may one day be used in gadgets. The wording then goes on to say these sapphire sheets would replace today's glass fronts used in phones, tablets and everything else, with Apple explaining at great length the many methods it may one day be asking the work experience kids at Foxconn to use in their manufacture.
