history of the touch screens
how do touch screens work
Touch screens are similar to monitors because they have a bezel or an overlay on the screen. They act like a computer monitor. When the screen is touched, the sensitive layers on the screen are designed to convert touch into a signal, as the layers transfer electrical signals between each other. The signal usually is identified by various sensors that are installed in phones.
