Improve ESD protection on mobile phone with capacitive touch screen

With the new technological products become to more and more friendly man-machine interface, the intuition type interface of touch screen make the user very easily use, therefore its need continuously grows up. After Apple releases iPhone, it leads a great deal of usage of touch screen. The electrostatic discharge (ESD) is categorized for the following four kinds: Human-Body Model, Machine Model, Charged-Device Model, and Field-Induced Model. The capacitive touch screen has control effect through fingers touch the touch screen causes some field change, so it is easy to meet problem of human-body discharge, making the ESD protection becomes very important. Today's 3C products require frivolous shortness, usually single components are all right, but whole assemble together can't pass ESD test, the combination with the body is very important.
