12.1inch touch panel / saw touch screen kit / Surface Acoustic Wave Touch Scree Touch kit
Surface acoustic wave (SAW) technology 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 acoustic wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen
Standard SAW touch screen, adopts 3mm or 4mm optical glass with fantastic clarity. Transducers sink into glass beveled edge which can prevent transducers from crush dangerous and facilities assembly.
