Touchscreen
The generation of smartphones.
Touchscreen utilization
As the price of the Touchsreen monitors had dropped over the past 10 years, they became very commonly utilized. Apart of the smartphones, touchscreens are also installed in some of the PCs and laptops. Such as "Asus" or "Toshiba" laptops, photos of which I've posted below.
How does it work ?
There are 3 main systems that are used to recognize the person's touch, here is one of them:
Resistive - consists of a normal glass panel that is covered with two metallic layers. These 2 layers are held apart by spacers, and scratch resistant layer is placed on the top of whole setup. When a person touches the screen while the monitor is active, the electric current runs throught the two layers, and they make contact in that exact spot.
