The latest report comes courtesy of the Wall Street Journal, which states that the first line of sapphire screens for its smartphones and watches is expected to come off production lines by the end of August.
Sapphire is currently used in the iPhone’s camera lens covers and the Touch ID fingerprint scanner on the iPhone 5S. It’s an expensive material to use, which may not be as much of a concern with regards to the iWatch, but the iPhone’s price could rise. After all, it will be significantly more expensive to produce enough to cover the entire face of a – potentially larger – device.
It shouldn’t come as any real surprise if Apple does utilise sapphire whenever possible. A sapphire display is much tougher than other displays, which is necessary on something like a watch. Plus, it was previously reported that Apple invested $700 million in a sapphire-production factory with GT Advanced Technologies, so it might as well get some bang for its buck.
