Been thinking about this, just curiously mystified.
The industrial panels that I know of all use resistive touch, rather than kapacitive touch.
Now why is that ?
I can only think of disadvantages with resistive touch, especially in an industrial environment.
The touch function is by a plastic film over the glass (or plastic). This film is quite sensitive to damage and wear. Use it with a sharp object and it is busted. Even if it survives, it gets worn over the time. I have seen lots of panels where the touch film has become completely dim and opaque where the operators press most frequently.
On my smartphone I have a glass touch screen that is remarkably resistant to scratches, and even after some serious abuse that has left some scratches, it still works perfectly.
Just curious ?
