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.
