What it is 10 point touch ?

- Sep 17, 2019-

10 point touch means is capacitive touch screen, is a layer of transparent special metal conductive material attached to the surface of the glass. When the finger touches the metal layer, the capacitance of the contact changes, so that the frequency of the oscillator connected to it changes, and the position of the touch can be determined by measuring the frequency change. Since the capacitance varies with temperature, humidity, or grounding conditions, its stability is poor and it often causes drift.

In general, a capacitive touch screen is a human-computer interaction method that supports multi-touch.
