Supply Of The iPhone’s Touch Sensitive Coating Is Running Out


Avocado for iPhone

When the iPhone was unveiled back in 2007, its touch screen was a revelation to the industry. You don’t need a stylus; you just touch it with your finger and it responds almost instantaneously.

While the iPhone’s touch display may feel a bit magical, the glass is coated in a thin, transparent material called indium tin oxide (ITO) that can sense when you touch the display. It’s one of those little tiny feats of engineering that you never really notice, except according to a new report from the U.S. government, supplies of ITO are dwindling and researchers are hustling to find a replacement.
