Sapphire just costs too much and doesn't make for good screens
Apple Inc. Reveals Bigger-Screen iPhones Alongside Wearables
Why Apple Didn’t Use Sapphire iPhone Screens
Apple’s long-awaited announcement of its new iPhone 6 and iPhone 6 Plus last fall came with an unexpected twist: Contrary to rumors, the company opted not to use an ultra-strong glass called sapphire for the devices’ screens. That was startling because Apple was involved in a major deal with sapphire company GT Advanced, ostensibly to provide the material for Apple’s newest phones.
After Apple announced its sans-sapphire iPhones, it was revealed that GT Advanced couldn’t deliver the amount of the material Apple required on time because of production issues. In a column I wrote last fall, I said Apple never planned to put sapphire screens in the iPhone 6 regardless of GT Advanced’s problems. However, it turns out that Apple did in fact enter into the GT Advanced deal wanting to use sapphire screens in its new iPhones, but by late 2013, the company realized that issues at GT Advanced meant that just wasn’t going to happen. Apple changed direction at the beginning of 2014, when it began working with Corning to deliver its newest version of Gorilla Glass for use on the iPhone 6.
Not long after the iPhone 6 was announced, the relationship between Apple and GT Advanced imploded, with the latter filing for bankruptcy. As of today, there’s no indication Apple is still seeking sapphire screens for any new iPhones — but its patent filings mean it’s impossible to rule out this possibility.
But there are other reasons sapphire won’t see the light of day in smartphones. First, it’s incredibly difficult to make sapphire screens in serious quantities at a cost that would make them feasible for even top-of-the-line smartphones. Also, the smartphone market’s trend toward bigger screens is making sapphire even more expensive to produce and buy.
