One of the biggest questions iPhone fans have about Apple’s next flagship smartphone is whether it will have a display made from sapphire. AppleInsider has found a newly published patent application that gives us fresh evidence that Apple has been toying around with sapphire displays, as it describes a method for coating sapphire displays to make them resistant to oily fingerprints.
AppleInsider notes that Apple first used such oil-resistant coatings with its iPhone 3GS, whose display was much smaller than what the iPhone 6’s display will likely be and wasn’t made of anything as fancy as sapphire.
We still don’t know for sure whether the upcoming iPhone 6 will have a sapphire display but between this patent application and the impressive sapphire production capabilities Apple has with its new plant in Arizona, we’d say it’s a distinct possibility.
