1.   RESISTIVE
2.   SURFACE ACOUSTIC WAVE
3.   CAPACITIVE

In resistive system a normal glass panel is covered with a conductive and a metallic layer of resistive. By spacers the two layers are separated from each other and the whole set up covered by a scratch resistant layer on the top so when users touches the screen the two layers make contact with each other with that exact spot and the change in electrical field is recorded and this coordination is calculated by the computer.
In surface acoustic system two sensors (one transmitter and one receiver) are placed with the horizontal and vertical axis of the monitor’s glass plate. If the wave has been disturbed, the receiving sensor will be able to detect and accordingly locate it .It do not leave any metallic layers on the screen and produce an absolute perfect picture quality. This makes the surface acoustic wave system best for displaying graphics.
In capacitive system a glass panel is placed with a layer of stored electrical charges and some of the charge is transferred to the users when he or she touches the monitor so charge of the capacitive layer decreases in the monitor where circuits located in each corner of the monitor measures the decrease of the charge.

This type of technology is obviously very beneficial as in this technology you don’t have to input any extra device such as mouse or a key board. the user only need his or her finger to manipulate the chosen device so the possibilities with touch screen monitors are endless .Touch screen computers are commonly used in medical field , stores ,industrial applications , cell phones , ATM machines etc. Touch screen technology used in I Phone has provided user a new leap in using various applications in a single touch.
