Not only 4: 3 touch screen, we also supply the following wide screen SAW TOUCH SCREEN / Surface acoustic wave touchscreen(16: 9)

Surface wave technology:
Surface acoustic wave (SAW) technology sends 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. In a strain gauge touch screen, the screen is spring mounted on the four corners and strain gauges are used to determine deflection when the screen is touched. This touch screen display technology can also measure the Z-axis.

Surface acoustic wave touchscreen is incomparable for clarity and reliability, even in public environment. It mainly features pure glass for durable scratch-resistant surface, superior image clarity, and light transmission. Furthermore, it is sensitive and fast on response, accurate touch position performance.

Advantage of SAW touch screen:
1. High touch resolution
2. High conductive speed
3. Highest image clarity
4. Reliable and long life to use
5. Durable, scratch-resistant glass surface, continue to work if scratched.
6. High touch point density
7. All glass panel, no coatings or layers that can wear out or damage
