Kinds of Touch Screen technology

• The resistive touch screen technology has functioning layers made up of electrically metallic conductive and resistive sheets which gathers voltage from back to front to permit the controller to compute the user's needs. This type of touch screen is affordable and resists dust and water, but it can be damaged by sharp items which come to contact.

• The surface wave touch screen technology on the other hand applies ultrasonic waves on the screen panel. This in turn sends the information required to process the user's activities. This is the most advance technology available for a touch screen.

• The capacitive touch screen technology is layered and stores electrical charges. Upon the user's touch, it is immediately transmitted for the processing of the information. It can only use fingers to harness the screen unlike the resistive and surface wave technologies which can make use of both fingers and stylus for navigation.
