Even a Knife Can't Scratch This 'iPhone 6' Display

A video purporting to show Apple's upcoming 4.7-inch iPhone 6's new display demonstrates how even a sharp knife can't scratch its surface.

YouTube user Marques Brownlee says he has gotten his hands on the super-durable sapphire crystal display and demonstrated just how much of a beating it can take. In addition to a knife, he scrapes keys on the glass surface display and not a single mark is left behind.

"This isn't a mockup," Brownlee said. 

"This is an actual, straight-off-the-assembly-line iPhone 6 part from Apple."

Brownlee thanks Sonny Dickson, who has a long history in obtaining iPhone parts ahead of launches, for obtaining the display.

Unlike Gorilla Glass, the protecting layer on the iPhone 5S, sapphire crystal is paper thin (the actual thickness of paper) and can endure intense pressure. Apple already uses sapphire crystal for its iPhone 5S camera, and the material is often found in high-end watches as well as some other camera lenses.

The video also shows how bendable the display is; Brownlee uses his shoe to try to bend and break the surface.

This not only means next-generation iPhones could be unscratchable, but users may not need a screen protector anymore, either.
