A touch screen is a device placed over or above a display which provides a signal when the screen is mechanically touched. A touch screen allows the user of a terminal to enter a menu selection or data by placing a finger or other object at a location on the display screen that corresponds to the menu item, function or data numeral to be entered. Touch screens are becoming more prevalent as data input interfaces as computers and other electronic devices become more ubiquitous. For example, touch screens may now be found in workshops, warehouses, manufacturing facilities, restaurants, and on personal digital assistants, automatic teller machines, cash register-inventory control devices, CRTs and flat panel displays,  POS (point of sale), kiosks, gaming systems, industrial control, telephone, control devices and general purpose computers. Touch screens are frequently used in combination with conventional soft displays such as cathode ray tubes (CRTs), liquid crystal displays (LCDs), plasma displays and electroluminescent displays. The touch screens are manufactured as separate devices and mechanically mated to the viewing surfaces of the displays. There are a variety of detection methods used in touch screen devices, including capacitive, surface acoustic wave, infrared, and resistive (with either 4 wires, 5 wires, or 8 wires). The two most popular touch technologies are analog capacitive and resistive touch screens. Resistive wire touch screens are built upon a substrate that is coated with a resistive film, typically indium tin oxide (ITO) at a specified thickness, uniformity and resistivity. The resistive touch screen works by applying a voltage across a resistor network and measuring the change in resistance at a given point on the network where a screen is touched by an external source. A capacitive touch screen generally includes a capacitive sensing circuit with multiple sensor bars that each produce an electric field. A touch in proximity to one or more of the sensor bars modulates the electric field and creates a signal. In general, capacitive and resistive touch technologies both rely on overlays, whereas infrared and SAW configurations typically do not require overlays. Touch screens can be activated by many different types of contacts, including by finger, pen, and stylus.
