Overview
Alternative to resistive touch screens. Capacitive touch screens can sense specific touch locations . Capacitive touch screens do not require any actual force to be applied to the screen’s surface. Capacitive are resistant to scratches and abrasion
Product Details
Working Principle
Please see the picture which shows the basic working principle: When body, as the earth capacitance, touches the electrode, capacitance CF will be formed between the induction electrode with the earth. The induction capacitance usually ranges from several pF to tens of pF. Making use of this basic principle, related circuit outside is established, and IC can detect if body touches electrode by the changing of capacitance.
Applications
The capacitive touch keypad owns durability, temperature resistance, water-proof, low cost and other advantages. It’s widely applied to home appliances and industrial control.
