Capacitive Touch Display

Capacitive touch display consist of a display and a touchpad. Controls are usually already integrated. Some people refer to the capacitive touch screen panel as a touch pad. In any case, it involves the possibility of making inputs in a larger area in order to read outputs or display the keyboard and inputs or outputs at the same time.

How does a capacitive touch display work?

Capacitive touch display consist of a thin layer of conductive material, such as copper or indium tin oxide (ITO), printed on the underside of the insulating outer layer of the display. When a finger touches the screen, a small charge is attracted to the point of contact, effectively turning it into a functional capacitor. The resulting change in the electrostatic field is then measured to pinpoint where the contact occurs.
