Touch Screen

Before the emergence of Smartphone, Touch Screen was a thing of fantasy and extreme luxury. Old
models of Smartphone were featured with a stylus by its side to use its highly delicate touch screen. Now touch-screen has become the
fundamental identity of a Smartphone. This is further enhanced by the multi-touch functionality which can track gestures of multiple
touches.

Recent findings of Apple’s patent demonstrated a new technology in material science which could merge screen and touch pad together.
Though this might sound simple, it has the capability of changing the form factor of Smartphone. Currently, a touch pad is layered on
top of the screen panel. Therefore the thickness of the phone is controlled by the thickness of these two sections. But once these
become a part of each other, the size is reduced making phones compact.

There are a lot of speculations regarding Touch Screen Technology due to the emerging interest in Tablet which is the laptop size screen
with multi-touch facility. The technology is also going to change the way we might design an interface for the Smartphone.
