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.
