The upcoming iPhone is reportedly being designed with a Sapphire Crystal display after Apple and GT Advanced landed a deal to institute a facility in Mesa, Ariz. dedicated to manufacturing sapphire crystal components.

Apple has been reported to be "aggressively" pushing to start up the operations of the said facility earlier this year and is purported to produce a "critical" and "new" sub-component for the upcoming Apple devices.

The company has kept mum regarding their joint plans with GT Advanced but new documents reveal information that provided a peek of Apple's design. It shows records of GT Advanced's orders of Intego Sirius Sapphire Display Inspection Tool components. The documents were shared by analyst Matt Margolis to 9to5Mac.

Contrary to previous news that these sapphire crystals will form part of cameras or home buttons, the machines are shown be specifically for display-grade elements. They are shown to be large and capable of simultaneously processing sapphire crystal screen covers.

GT Advanced has also ordered other tools in the past months, most notably a number of furnaces and chambers. Together, these separate pieces convert the sapphire crystal into large hockey pucks called "boules." After which, they are polished and made into shapes of displays.

As indicated in shipping documents from Margolis, 518 units have been received by GT Advanced while another 420 of it are pending assembly. These machines are said to build 5-inch displays numbering from 103 million to as much as 115 million annually.

The other machines scheduled to add to their growing plethora of equipment could double up the number they can make every year with around 84 to 94 million covers. Their orders also include 100 tons of graphite material that will be used to heat the furnaces.

If Apple will produce sapphire crystal displays for their future iPhones, it would mean a much stronger and scratch-resistant display. The iPhone 6 is said to have a larger screen with curved glass edges.
