SAW Touch Screen Technology


Surface Acoustic Wave (SAW) touch screen technology 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.

Like infrared technology, the panel is all glass, so there are no layers that can be worn, or damaged over time. This makes SAW touch screen technology highly durable and suitable for applications where high clarity is desired.


SAW touch screen technology is recommended for public information kiosks and other high traffic indoor environments.

In Australia SAW technology is usually one of the more expensive technologies. Since there are few applications where it is superior to infrared, infrared is more often the recommended solution where high durability and screen clarity is required.

Limitations of SAW Touch Screen Technology

  • Must be touched by finger, gloved hand, or soft-tip stylus. Something hard like a pen, credit card or finger nail won’t work
  • Can be affected by large amounts of dirt, dust, and / or water in the environment.
