iPhone 6 to Have Sapphire Phone Screen



Forbes published an article yesterday claiming to have proof that Apple is going to use a scratch proof Sapphire screen in its upcoming iPhone 6. The article also says that the phone will be released in the second half of this year and not in May as some had expected. The iPhone 6 Is Not Coming In May, But It Is Coming With Sapphire - Forbes

Most high end smartphones these days are made using Gorilla Glass. Gorilla Glass is the registered trademark for an alkali-aluminosilicate sheet toughened glass manufactured by U.S. glassmaker Corning Inc. However even the best gorilla screens are still very prone to scratch crack, break, and shatter. So another company - GT Advanced has come up with synthetic Sapphire as a replacement for glass. Sapphire is a naturally growing crystal and is the second hardest substance on earth. It’s so hard, only diamond-tipped saws can cut it. It really has excellent scratch resistant properties as demonstrated in the video above.



GT Advanced grows sapphire and then melts and hardens them into 115kg cylindrical ‘boules’. Those cylinders are then cut into screen shapes


Apparently Apple has placed large orders for Sapphire with GT Advanced and this is the basis for Forbes report. Corning responded to the reports by saying that "Sapphire's performance as a cover for high-end watches probably leads to the current speculation. But those covers are much smaller than a mobile phone and are two to three times thicker than Gorilla Glass. In one of our commonly accepted strength tests, sapphire breaks more easily than Gorilla Glass after the same simulated use. Additionally, sapphire’s cost and environmental hit are huge issues."

Apple will be the first smartphone maker to use Sapphire screens on such a large scale. It will be interesting to see how this works out in general mass use.

Re: iPhone 6 to Have Sapphire Phone Screen

Now this is something new. Good move.
Atleast its better than the pathetic crap peddled by Samsung as SGS 5

Re: iPhone 6 to Have Sapphire Phone Screen

I am highly impressed, this is a welcome step for the world.
But why does Corning give the impression that it breaks easily ..

They are trying to be sore loosers..

Re: iPhone 6 to Have Sapphire Phone Screen



BTW, the iPhone will not be the first smartphone to use a Sapphire screen. The Vertu Constellation which is a Android phone was the first smartphone to use a sapphire screen.

Synthetic sapphire is also used as the glass in high end watches. It has also been used in military and aerospace applications from many years.

Re: iPhone 6 to Have Sapphire Phone Screen

This looks good.
With the recent acquisition of large scale production technology for synthetic Sapphire, there there is no reason why Apple wouldn't choose Sapphire.
They wouldn't need to purchase Gorilla from Corning, which would give them additional flexibility in contract timing, etc.

I hope Apple can meet the demands (if iP6 sell that is), and not end in a shortage of phones.
