| What is a surface acoustic wave touch screen? |
* Answer
| Surface acoustic waves are a type of ultrasonic wave that is a mechanical energy wave that propagates shallowly on the surface of a medium such as glass.The surface acoustic wave performance is stable, easy to analyze, and has very sharp frequency characteristics during the transverse wave transfer process.The surface acoustic wave touch screen is very stable, free from environmental factors such as temperature and humidity. It has a long life (about 50 million touches), high light transmittance and high definition, no color distortion and drift, no need to be calibrated after installation.Good scratch resistance, can withstand all kinds of rough touches, and is most suitable for use in public places. |
