About Touch Screen Sensors

Touch screen sensors are composed of a transparent touch screen surface surrounded by a sensor array that provides positional information to a processor. A touch screen sensor enables the display to be used as input device and replaces the keyboard or mouse as the primary method of input for interacting with a display's content. Touch screen sensors can be attached to computers and handheld devices. Touch screen technology is used by banks in the form of automatic teller machines (ATMs).

There are several basic types of touch screen sensors. Examples include capacitive glass touch screen sensors, resistive touch screens, and complete touch screen systems. A capacitive glass touch screen sensor is placed on a touch screen panel that is coated with indium tin oxide. The panel conducts a continuous electrical current across the sensor in order to detect changes in capacitance. A resistive touch screen panel is also coated with a thin-film, but in order to produce an electrically resistive layer. Each change in electrical resistance is marked as a touch event and sent to a controller for processing. A complete touch screen system allows a user to operate a computer or terminal by touching the display screen. A touch screen system consists of a touch screen sensor array, a controller card, and a software driver.
