The super-tough sapphire glass screen will be included in the iPhone 6, which is not just a rumor or a wish any more, since an expert who spoke to Apple confirmed it with the Guardian.
You might be impressed with a video leaked this Monday, showing a 4.7-inch sapphire screen being attacked by a knife and a bunch of keys, and bent under a foot without any scratch, dent or break.
Now the alleged sapphire screen could "well be legitimate," according to Professor Neil Alford of the department of materials at Imperial College, London.
“I think Apple have been quite cunning,” Alford tells the Guardian. “What I think they’ve done is make a screen out of sapphire, which is incredibly scratch resistant, incredibly hard and has a high elastic modulus – meaning it’s very stiff.”
In fact, the Cupertino-based company has been working on that as early as 18 months ago. “I remember the Apple folk coming to speak to me about 18 months ago to discuss sapphire screens,” Alford says. "They’ve obviously been busy since then, working with a sapphire manufacturer."
“It’s not a surprising thing to do, but it’s quite a large area they’re producing and that’s really quite a challenge. I’m pretty impressed with that, actually,” Alford continued.
Alford even comments on the Youtube video aforementioned, saying “In my opinion the screen being shown off in the video could well be a sapphire screen. If you make sapphire thin enough, and it’s flaw free, you can bend it quite considerably because it has an enormous strength.”
Sapphire crystal has been used for the iPhone’s camera lenses and the cover of the iPhone 5S's Touch ID fingerprint sensor, but the durable material will be the first time to be used for its front cover.
In addition to an excellent display, the iPhone 6 will possibly include a thinner housing, improved camera, A8, iOS8 and more.
