Capacitive Touch Screen

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.

What Does Capacitive Touch Screen Mean?

A capacitive touch screen is a device display screen that relies on finger pressure for interaction. Capacitive touch screen devices are typically handheld, and connect to networks or computers via an architecture that supports various components, including satellite navigation devices, personal digital assistants and mobile phones.
A capacitive touch screen is activated by human touch, which serves as an electrical conductor used to stimulate the electrostatic field of the touch screen. However, special gloves that produce static electricity or specialized stylus pens may be used.
Capacitive touch screens are built into input devices, including all-in-one computers, smartphones and tablet PCs.

Capacitive touch screens are control displays that utilise the electrical properties of the human body as input. When a finger (or specialised input device, such as stylus) comes in contact with the display it detects when and where on the display the user touches it. As a result capacitive displays can receive accurate input from very light touches.
