Recently published patents reveal that Apple has plans to further expand its use of sapphire as a construction material for the iPhone 6.
When you think of sapphire, you imagine a lavish, blueish jewel — not a critical construction material for a smartphone. However, the use of sapphire has continued to increase with the iPhone, and recent patents suggest that the iPhone 6 could feature a significant amount of sapphire used to protect its screen.
According to an article in the IBTimes, a relatively new Apple patent reveals a new ” . . . method of fusing a sapphire laminate sheet to a device’s cover glass,” according to Patently Apple. The purpose of adding sapphire to the cover glass is not to add “bling” to the device, but rather to significantly bolster its strength and resilience.
To wit, sapphire has been used on the iPhone for a while now: the rear camera’s lens on the iPhone 5 features a sapphire coating. After rumors of sapphire increasing in Apple’s supply chain this year, we’re seen it further implemented with the iPhone 5s’ new capacitive, fingerprint-scanning home button. The iPhone 6 is anticipated to further increase the use of the material to protect the entire screen.
The iPhone already features pretty tough “gorilla glass.” However, it is anticipated that the sapphire-sealed glass on the Phone 6 would be virtually impervious to scratches.
