The Application Scene Of Various Touch Screens。

- Jul 29, 2019-

Capacitive sensing touch screen: Since the capacitance varies with temperature, humidity or grounding, its stability is poor and it often causes drift.  In case of electromagnetic field interference and drift, not easy to be controlled in industrial places and places with interference. It can be used for public information queries that require less precision; it needs to be calibrated and positioned frequently.

 

Infrared sensing touch screen: low resolution, but not subject to current, voltage and static interference, suitable for some harsh environmental conditions; suitable for all kinds of public places, offices without infrared and strong light interference, and industrial control site that is not very precise  

 

Surface acoustic wave touch screen: pure glass material, best light transmission, long service life, good scratch resistance, suitable for all kinds of public places of unknown users. However, it is better to use it in a clean environment  in case of long-term dust accumulation and oil staining. Otherwise, regular cleaning services are required.
