Leak: The 'undestructable' Apple's iPhone 6 screen

Marques Brownlee, a YouTube video maker claims to have gotten hold of one what appeared to be the screen of the Apple’s iPhone 6 made from sapphire crystal, and has subjected it to a variety of extreme stress test, from stabbing it with a knife and keys to bending and twisting it.

In the video, after subjecting it to a variety of extreme stress test, the screen emerges totally unscathed, raising hopes is could lead to a far more resilient handset from Apple.

'I slowly realized there is absolutely no way I can break this display under my own power,' he said.

'The worst blemish on the surface was actually my fingerprint marks and the dust from handling it so much.'

The only explanation Brownlee offered for how we came into possession of the new 4.7-inch screen was "it's 2014; everything leaks"—a maxim proved by Steve Hemmerstoffer's YouTube channel, which has uploaded a Chinese-language video showing the same screen being subjected to even more outrageous tests.

Apple already uses a small amount of sapphire glass for the 'Home' button and camera lens in the iPhone 5S.

Reports Apple was experimenting with sapphire displays began last year, yet sources claimed at the time Apple found the technology ‘infeasible.’

This was because sapphire glass is more expensive to produce than normal screens.

However, Apple recently announced plans to open a mineral plant in Arizona with sapphire glass experts GT Advanced Technologies.

The facility is expected to employ around 700 people to manufacture sapphire crystal and sapphire glass, and this technology could make its way onto the screens of the next iPhone.

 

The iPhone 6 is scheduled for an official unveiling on Sept. 19, and will go on sale shortly after.
