The video posted on Sony Dickson's Twitter and YouTube channels shows a pair of hands bending the sapphire screen with considerable force, and each way that the glass is bent once the tension is released the glass goes straight back into its original shape.
It's been very heavily rumoured that the iPhone 6 will launch with a sapphire display and the recent leak seems to confirm all of our suspicions.
Sapphire has some very desirable qualities that make it an ideal material to use in smartphone displays. As you'd expect it's very transparent between 150nm (ultraviolet) and 5500nm (far-infrared).
It is also ridiculously strong compared to normal glass, and screen scratches on your iPhone will become a thing of the past, as it’s one of the most scratch-resistant materials in the world. It scores 9 on the Mohs scale of mineral hardness, one down from diamond’s 10.
From the video below it's unclear whether the screen being flexed is from a 4.7-inch or 5.5-inch iPhone 6.
Sonny Dickson has released the full version of his look at the which is confirmed to be a 4.7-inch glass panel for the white iPhone 6.
