It looks like Apple has already paved its track to mass-produce scratch-proof sapphire crystals for its future iPhones. So most probably, the days of screen protectors are close to getting extinct, at least for iPhone users.
According to the report from 9to5Mac, the Cupertino giant has already made a move to set up a manufacturing plant in Mesa, Arizona in collaboration with the New Hampshire-based GT Advanced Technologies. The plant is reportedly said to be capable of producing 100 to 200 million smartphone-sized displays per year.
Moreover, the New Hampshire-based GT Advanced Technologies which will be operating the plant, reports suggest that it has received hundreds of furnace and chamber systems for producing "boules" of sapphire crystal. With further processing and polishing, these "boules" can become screen-sized sheets of sapphire.
When it comes to how the company plans to use the sapphire crystal, there are various possibilities. Apple might use it for display protection, as camera lens covers, TouchID home button embedded on iPads and iWatch.
However, Apple's sapphire crystal technology is just a speculations as of now. May be the same will feature in the company's this year's flagship device, the iPhone 6.
