In the lead-up to the iPhone 6, everyone expected Apple to give it a sapphire glass display. Sapphire glass, it was said, would lead to nigh-indestructible screens: Scratched and shattered iPhone displays would become a thing of the past.
Of course, we all know what happened from there. Apple’s sapphire partner, GT Advanced Technologies, completely collapsed, and the iPhone 6 shipped with plain old Gorilla Glass. Yet even if it hadn’t, Apple might not have used sapphire glass, which was much more reflective and harder to read in ambient light than Gorilla Glass.
But here’s the key word: was. A new technology has emerged that might make sapphire glass every bit as good when it comes to viewability as Gorilla Glass.
