The company invested $578 million in order to make up a stock of sapphire panels high enough to meet demand in the coming years.
But Apple’s move could signal a major change in the future as the company is rumored to be planning to use sapphire displays in its next-generation iPhone instead of the current Gorilla Glass.
According to TechCrunch, a company called Twin Creeks has developed a hydrogen ion particle accelerator that allows cutting very thin slices of sapphire glass.
The new particle accelerator could simplify the cutting process, as sapphire is known to be very hard and difficult to cut, and reduce production costs for the manufacturing of sapphire screens.
The iPhone 6 is expected to feature the rumored sapphire display.
