Surface Acoustic Wave (SAW)

Touch Technology

A D Metro offers a complete line of Surface Acoustic Wave (SAW) touch screens kits, consisting of touch screen and controller.

SAW offers an excellent alternative for many touch applications requiring a light touch, excellent optical characteristics and a very durable surface. Since the sensor is basically a glass plate with no coatings, the technology is quite robust and offers excellent optical characteristics.

How do Surface Acoustic Wave Touch Screens Work?

Surface Acoustic Wave (SAW) touch screen sensors use ultra-sonic sound waves over the touch screen surface, aided by a reflective pattern around the periphery of the sensor. When touched by a finger, the ultra-sonic waves are disturbed and the touch location can be detected. Since active sensing is around the perimeter of the sensor, the touch screen can offer excellent optical clarity.
