"There has also been a reported $2.6bn investment in LCD production by Apple partner Foxconn. The new plant will begin mass production of LCD panels exclusively for Apple by the end of 2015, after
Apple made a request to ramp up production. This again dampens previous speculation that Apple will move to Oled display technology for its next iPhone.
While the design is unlikely to change much, rumours suggest that Apple might opt for a scratch-proof sapphire display in the next-generation iPhone, such as that found on the Apple Watch.
Production problems reportedly prevented the iPhone 6 launching with a sapphire screen, but speculation claims that Apple has teamed with Foxconn to get the tough displays ready in time."
