Capacitive touch is a common touch mode. When industrial capacitive screen fails, how to solve it? What are the principles to follow? Here let's talk about it.


The so-called "Drift phenomenon" of capacitive screen mainly refers to the following situations:


1. Making mistake action to touch operation, i.e. when touching point A location, touching response from point B location; 

2. Without touching, but shows a mistake action, it refers to the body or conductive material is close to the screen, and has not touched, but it will make a touching response;
