The iPhone 6, which is expected to be released next year, may come equipped with a sapphire glass screen. To achieve this goal, Apple has already spent $578 million. Currently, Sapphire material is only used on Apple products for the iPhone 5s Touch ID fingerprint sensor and lens protection glass. If the iPhone 6 uses sapphire glass, the demand for this material will be very high.\
\According to Jeff Nestel-Patt, marketing director at GT Advanced Technology, sapphire material does not scratch. Its durability is 2.5 times that of the well-known Corning Gorilla Glass, which is currently used in many smartphones on the market. At present, if sapphire screens are to be used on the iPhone 6, two factors need to be considered: mass production and the cost of the material. GT Advanced Technology states that the cost of sapphire material is four times that of Corning Gorilla Glass. Of course, large-scale production can further reduce the cost, and this material is likely to become the standard for future smartphones.\
\Linda Reinhard, Vice President of Business Development and Product Management at GT Advanced Technology, describes the company's product as being very suitable for protecting smartphones and camera lenses. Glass can only have its strength increased through chemical or other methods, whereas sapphire material is inherently strong. To accelerate the mass production process of the next generation of sapphire material at GT Advanced Technology, Apple invested $578 million.\It is believed that the iPhone 6, expected to be released in 2014, will feature an entirely new design. Many analysts and mainstream media believe that the iPhone 6 will come with a larger display.
