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.
