SAW touch screen description:

GreenTouch Surface Acoustic Wave (SAW) touch screen uses ultrasonic waves that pass

over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed.

This change in the ultrasonic waves registers the position of the touch event and sends this

information to the controller for processing. Surface wave touchscreen panels can be damaged

by outside elements. Contaminants on the surface can also interfere with the functionality of

the touchscreen.

GreenTouch Surface Acoustic Wave (SAW) touch screen is based on sending acoustic waves

across a clear glass panel with a series of transducers and reflectors. When a finger touches the

screen, the waves are absorbed, causing a touch event to be detected at that point. SAW touch

screen technology is recommended for public information kiosks and other high traffic indoor

environments.
