Apple is planning to use sapphire crystal glass technology in its next iPhone, after details emerged of equipment it had purchased.

The iPhone maker has struck a deal with GT Technologies which will allow the firms to produce between 100 and 200 million displays at a manufacturing facility in Arizona.

Documents showing the import of materials were published by 9to5Mac and appear to confirm that Apple and GT Advanced will be working together to produce larger displays.
