Apple patent application details uses for synthetic sapphire glass

“An Apple patent application describing a method of mounting sapphire to an electronic device was discovered on Thursday, with example implementations possibly revealing how the company plans to employ the exotic material in future products,” Mikey Campbell reports for AppleInsider.

“The U.S. Patent and Trademark Office published Apple’s patent application for ‘Attachment techniques’ detailing various methods in which sapphire can be securely fastened to an electronic device,” Campbell reports. “For example, Apple notes sapphire may be attached to a portable device frame as a cover glass for a display. Current iPhones use Corning’s Gorilla Glass to protect the important component from scratches and damage, but it is possible that Apple may be looking to incorporate sapphire in future versions of the smartphone. While aluminosilicate glass solutions like Gorilla Glass perform well, certain advanced sapphire laminates can be even more resistant to daily wear and tear. ”

“Sapphire was first used in the iPhone 5 when Apple applied the hard material as a lens cover for the handset’s rear-facing camera. With the current iPhone 5s, sapphire plays a more critical (and functional) role as the cover glass for Apple’s Touch ID fingerprint sensor,” Campbell reports. “In November of 2013, crystal growth and solutions firm GT Advanced Technologies announced it had signed a $578 million contract to provide Apple with advanced sapphire products, almost guaranteeing future iDevice products will incorporate the material in some capacity.”

  1. By the by, does anyone know the relative cost of saphire glass v gorilla glass?
    I should imagine 30m plus iPhones account for several tones of the suff just for lens covers. Are the milling trimmings recoverable and reusable?

  2. That’s because – unlike the universe, iProducts aren’t created in 7 days.

    I’m pretty sure there is more $$$$ spent on figuring out how to make an iPhone then the device itself.

    Just as the advances in tech that led us to the iMac, iPod, iPhone, iPad – there is a whole new crop of things we haven’t even imagined being invented, patented, developed, engineered and produced in some way by apple.

    No other company, group, organization can come close to doing what Apple does on the scale it does time after time. And do it with the money they earned – not awarded..

    -t

    1. I agree, although I mistakenly gave one star by accident; I couldn’t add more, sorry.
      What I would dearly love to see with the iP6 is a Liquidmetal frame, sapphire glass front and rear, with a size around five inches, and 128Gb of storage.
      Just about perfection, as far as I’m concerned.
