Touch monitorsTouch Monitors: Practical and Cost-Effective Solutions for Business and Personal Use
Touch screens offer exceptional convenience and accessibility for a variety of computing and technological applications. Touch monitors are especially useful in this regard, since they combine the properties of an advanced display system with the functionality of touch screen input. Durable and versatile, touch monitors have been integrated into medical environments, vehicle control systems and the ordering processes in fast food establishments as valuable tools that allow faster response times. Tablet computers and touchscreen cell phones are among the most popular versions of touch monitor systems and provide easy portability along with advanced graphical user interfaces.
Like other touch screens, touch monitors use one of three basic methods to register the presence or pressure of a finger on the screen.
Resistive touch monitors require a certain amount of pressure in order to function properly, since these devices depend on an interruption in the electrical field generated just between a conductive and a resistive layer. When pressure is applied to the panel, the electrical charge is interrupted and advanced software records the location of the interruption for interpretation and action. Resistive touch monitors typically produce lower contrast images than the other two types of touch monitors.
Capacitive touch monitor systems incorporate a charged layer on the surface of the glass panel. When a conductive object touches the panel, the charge is interrupted and the data interpreted in the same way as with resistive monitors. However, the item used to touch the screen must be conductive; rubber gloves and other nonconductors will not create the proper connection with the screen.
Surface Acoustic Wave
One of the newest and most advanced technologies for touch monitors is the surface acoustic wave system. This method uses a receiving and a transmitting transducer that actually detects wave disturbances in the electrical field, allowing it to be more responsive than other methods. Additionally, this method does not reduce the amount of light produced by the screen, allowing brighter, sharper images to shine through. These systems can be activated by touch or by light pressure, allowing them to be functional in a larger variety of environments and work conditions as well.
Touch monitors are part of everyday life and offer significant benefits to companies and individuals interested in saving time and working more effectively. Additionally, touch monitors can help to eliminate errors by controlling the number of possible responses and providing feedback when the input is unexpected and may be in error. High quality touch monitors provide years of service in office, medical, kiosk and other work settings and the increased productivity these systems can provide more than justifies the initial costs of purchase.
