Monitor Touch Screen has become more and more commonplace over the past decade. Besides a huge price drop in these years, Monitor Touch Screen are relatively easier to operate and this marks the increasing popularity of Monitor Touch Screen. There are three basic systems that are used to recognize a person's touch in a Monitor Touch Screen. They are resistive, capacitive and surface acoustic wave system.

The Monitor Touch Screen, with the resistive system consists of a normal glass panel that is covered with a conductive and a resistive metallic layer. An electrical current runs through the two layers, while the Monitor Touch Screen is operational. When a user touches Monitor Touch Screen, the two layers make contact in that exact spot. Once the coordinates on the Monitor Touch Screen are known, a special driver translates the touch into something that the system can understand.

In a Monitor Touch Screen with a capacitive system, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the Monitor Touch Screen with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the Monitor Touch Screen. The computer calculates where the touch event took place and then relays that information to the Monitor Touch Screen driver software.

Monitor Touch Screen with the wave system has a receiving transducer, which can tell if a wave has been disturbed by a touch event at any instant, and can locate it accordingly. The wave setup has no metallic layers on the Monitor Touch Screen, allowing for 100-percent light throughout and perfect image clarity. This makes the surface acoustic wave system, the best system for displaying detailed graphics on a Monitor Touch Screen.
