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.

Resistive

A D Metro’s resistive touch products include two styles of sensors. Choose either our conventional, standard resistive sensors or our patented ULTRA armored resistive sensors. ULTRA sensors are proven in the most physically demanding touch applications.

Projected Capacitive (PCAP)

Projected Capacitive (PCAP) touch screens offer the user friendly multi-touch experience, associated with smartphones and tablets, operating with very light touch through a highly durable glass surface.

Infrared Optical

An infrared touch screen application is composed of a frame outfitted with LEDs and photodetectors. The frame has an optical bezel or protective cover that enables LEDs to emit infrared beams, invisible to the naked eye.
