Review:
Surface Acoustic Wave (saw) Touchscreens
overall review score: 3.7
⭐⭐⭐⭐
score is between 0 and 5
Surface Acoustic Wave (SAW) touchscreens utilize surface acoustic waves that pass across the screen's surface to detect touch input. When a user touches the screen, it causes a disturbance in the acoustic wave pattern, which is then interpreted as a touch point. This technology is often used in interactive kiosks, industrial displays, and point-of-sale systems due to its durability and optical clarity.
