Earlier this month it was reported that Apple has signed an agreement with GT Advanced Technologies, a company that processes the sapphire.
Cupertino has reportedly invested $578 million to make up a stock of sapphire panels high enough to meet demand in the coming years.
In addition, a company called Twin Creeks has developed a hydrogen ion particle accelerator that allows cutting very thin slices of sapphire glass which could help simplify the cutting process.
A Forbes article by Nigam Arora gives several reasons on why the next iPhone might incorporate a sapphire display.
This sapphire isn’t of a natural type, it is rather a man-made version of the substance.
One factor that could make Apple choose this type of screen refers to the fact that it makes the display very scratch-resistant and nearly unbreakable thanks to the aluminum oxide-based substance.
Another advantage is its quality of being extremely thin, much thinner than the frequently-used Corning Gorilla Glass.
An interesting aspect about such a display is connected to an Apple patent about the use of sapphire layers to form a screen.
This could be done by fusing an outer sapphire layer with an inner glass one.
Do you think Apple would debut such a technology in the iPhone 6?
