No.1 Single touch screen can adapt to all kinds of harsh environment,and it can accurately touch the resistance screen.

No.2 The service life of single touch is longer than that of multi-touch capacitor screen.

No.3 Single touch only means you can touch one place at a time, and if you touch another place, it doesn't work.

Multi-touch screen:
