From the latest rumors about Apple 6, one of the concerns is about the size and sapphire screen. Apple has been using Corning reinforced glass with high durability and scratch resistance in mobile phones. However, the latest news shows that with the launch of the iPhone 6, Apple will terminate the cooperation with Corning, because Apple will use sapphire glass in future iPhone series products. This is Apple's most secret weapon to defeat Samsung.
Sapphire screen of Apple will greatly improve the service life, and the appearance will be very exciting. Maybe in the near future, all Apple mobile phones will adopt this kind of material. Will the large screen sapphire glass Apple phone become the secret weapon to overwhelm Samsung?
Sapphire glass has the characteristics of high hardness and wear resistance, which is mainly used for the surface of high-grade watches. Currently, the sapphire glass has been used in camera lens of iPhone and fingerprint scanning sensor of iPhone 5S.
Apple is said to have invested $500-700 million in the first six months to produce sapphire glass, because the cost of producing sapphire glass screens is 3-4 times higher than that of Corning Glass screens.
