Earlier today we got a quick look at a flexible iPhone 6 display, but a new video from YouTuber Marques Brownlee (embedded below) takes the supposed next-gen screen through a more complete durability test. In the video, Brownlee not only bends the flexible sapphire panel, but takes a set of keys and even a knife to it in an attempt to leave a scratch.

The beginning of video features a look at the sapphire crystal that will reportedly make up the next-generation iPhone’s display. As demonstrated in the video, the glass is extremely clear (which is why Apple currently uses it in the iPhone’s camera lens and the Touch ID sensor on the 5s). After a quick examination of the crystal-clear glass, Brownlee really put it to the test…


In the second half of the video, Brownlee puts the iPhone display through a quick scratch test using a pocket knife and a set of keys. When he’s unable to leave so much as a tiny scratch on the panel’s surface, he moves on to a bend test with similar results, as you can see in the video above.

Though there’s still much testing to be done, the sapphire crystal display held up very well. By the end of the test, Brownlee concluded that he would be unable to actually leave a mark on the panel without mechanical assistance.

At the end of last month, 9to5Mac exclusively uncovered comparison photos of both the black and white versions of the soon-to-be-announced iPhone 6 display. It’s also been rumored that the upcoming device will not feature as much additional battery life as many users were hoping for due to its thinner design.
