How Does a Touch Screen Work?

Answer

A touch screen sensor detects a voltage change caused by the electricity from the cells that form our fingers and that voltage change is used to determine the exact location where the screen was touched. To accomplish this, the touch sensor is placed over a display screen so that the responsive area of the glass panel covers absolutely all the viewable areas of the screen. Once the voltage change has been located, a controller transforms this input into something that a computer can understand. A software driver then tells the computer how to interpret the touched information that comes from the controller.
