US 2013/0154994 A1 · TRANSPARENT CAPACITIVE TOUCH PANEL WITH ELECTROMAGNETIC SHIELDING EFFECT

Abstract

A transparent capacitive touch panel has electromagnetic shielding effect. No extra process and cost is increased. A side of the capacitive touch panel facing electromagnetic interference is formed with an electromagnetic (EM) shielding for avoiding the interference of EMI and RFI. As comparing with the prior art, advantages of the present invention are that the present invention achieves a complete EM-proof effect so as to provide a preferred EM shielding; the effect of EM proof of the present invention has no relation with the arrangement of X traces, Y traces; and the gaps between the traces of the present invention can be widened for having a better effect of EM proof so as to simplify the technology in manufacturing with a higher yield ratio and a lower cost.
