What are Capacitive Touch Screens?

Capacitive touch screens consist of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO). As the human body is also an electrical conductor, touching the surface of the screen results in a distortion of the screen's electrostatic field, measurable as a change in capacitance. In order to determine the location of the touch, you would use different technologies. Then, send the location to the controller for processing.

Capacitive touchscreens are those that respond to the electrical properties of the human body. This means that it is possible to control them with a light touch. So, the user doesn't need to exert heavy pressure on the screen. The drawback to a capacitive touchscreen, though, is that it usually cannot be controlled by a gloved finger or an input device, such as a stylus.

There are some input devices that have been optimized for use with capacitive touchscreens, though. Capacitive touchscreens also are the only ones capable of multi-touch, which allows the display to recognize more than one point of contact. Without multi-touch, you cannot use gestures such as pinching and spreading a screen to zoom in and out.
