What Goes into a Cell Phone Screen?
Perhaps one of the top features that makes modern cell phones so popular is the touch screen. It seems hard to imagine now, but only a little longer than a decade ago, the idea of swiping, pinching and zooming an electronic display on a personal phone was unknown outside of science fiction.
Most modern cell phones use a technology known as capacitive touch, which allows multi-touch operation. Unfortunately, this isn't as sturdy as the older, simpler one-touch screens, like those used in ATMs.
So, while the technology works brilliantly, it does mean that phones with multi-touch screens are a little more fragile than older models – and if the screen fails, the phone could be more or less unusable.
However, more recent screens have been toughened up using a special type of glass, called Gorilla Glass.
