Touch screen monitor
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 offers a simple, intuitive interface for a computer or other data processing device. Rather than using a keyboard for data entry, a user can transfer information through a touch screen by touching an icon or by writing or drawing on a screen. 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. Touch screens or touch panels are used as data input units to enable users to interact with a computer system for e.g. factory automation equipment, office automation equipment or automatic measuring device. Information can be displayed on the display and the user touches the display at a desired location corresponding to the desired information, image, or icon. When the user touches the touch detection overlay, the electrical parameters are changed, and by sensing the change from various positions at the edge of the overlay the position where the user touched the overlay can be inferred. Touch screen panels generally comprise an insulative substrate and a resistive layer disposed on the insulative substrate. A pattern of conductive edge electrodes are then formed on the edges of the resistive layer. The conductive electrodes form orthogonal electric fields in the X and Y directions across the resistive layer. Touch sensitive screen user interfaces facilitate the selection of copying parameters on a reprographic system. Such systems allow users to visually determine the copying feature set that has been selected prior to starting the job, as well as the status of the job during execution. Many display applications such as personal data assistants (PDAs), global positioning systems (GPS) and navigation systems incorporating GPS, airline check-in terminals, public computer kiosks, as well as a variety of other system and devices include touch screens that are added onto an information display panel so that a user may effectively see an icon or graphic for a data item or action, and by pressing a finger or stylus on that icon, select data item or action. Touch screen panels can be driven by resistive, capacitive, ultrasonic or infrared mechanism.
