How does a Capacitive Touchscreen Work?
Capacitive touch screens are built with a thin layer of conductive material, such as copper or Indium Tin Oxide (ITO), printed onto the underside of the display's insulating outer layer. When a finger touches the screen, a small electrical charge is drawn to the point of contact, which effectively becomes a functioning capacitor. The resulting change in the electrostatic field is then measured to pinpoint where the contact took place.
Projected Capacitive (PCap) touchscreens are used on the vast
majority of smartphones and tablets. PCap screens consist of a
layer of glass, a matrix of electrodes and a protective film. The
matrix of electrodes creates a three dimensional electrostatic
field that registers even the slightest change in electrical
current. So, when a conductive object, such as your finger or a
stylus, comes into contact with the matrix of electrodes, the
electric field is changed slightly, and the screen registers your
touch.

Capacitance Touchscreen Construction
Several techniques are available to construct a capacitance touchscreen. These include conductive wire construction or the application of transparent conductive materials, such as Indium Tin Oxide (ITO), to a polyester (PET) film layer "sandwich" or to a glass substrate.
