Washington: Apple iPhone 6 is rumored to get a sapphire crystal display cover glass, which is currently used for small surface parts only. At present the sapphire crystal cover glass has only been used selectively, the iPhone 5S home button uses a sapphire cover.
Sonny Dickson, a source of past Apple rumors, was one of the first to post a video showing a 4.7-inch flexible sapphire crystal display cover glass, CNET reported.
Another video uploaded by Marques Brownlee shows a test of the display screen. Brownlee proceeds to give the display a torture test of sorts by trying to scratch it and chip it with a knife, with apparently no scratches or damage to the display. He then bends and flexes the saying that there is absolutely no way one can break this display under my own power.
One of the questions that observers have raised is whether Apple would risk using its first sapphire display cover on a high-volume product with a relatively large display, like the rumored 4.7-inch iPhone 6. To date, Apple has used sapphire only on parts with small surface areas like the iPhone 5S home button and camera lens, the report added.
