A capacitive touch screen consists of a glass panel with a capacitive (charge
storing) material coating its surface. Circuits located at corners of the screen
measure the capacitance of a person touching the overlay. Frequency changes are
measured to determine the X and Y coordinates of the touch event.
Capacitive type touch screens are very durable, and have a high clarity.
They are used in a wide range of applications, from restaurant and POS use to
industrial controls and information kiosks.
