Abstract
A portable electronic device includes a touch screen and a first PCB. The touch screen includes an effective touch area and an ineffective touch area surrounding the effective touch area. The first PCB is mounted to a rear surface of the touch screen. An NFC antenna and a touch-sensing circuit are arranged around a peripheral area of a front surface of the first PCB and spatially correspond to the ineffective touch area. A transparent shielding layer is arranged on a rear surface of the first PCB and spatially corresponds to the peripheral area of the front surface to shield the NFC antenna from electrostatic interference caused by electrical elements located under the first PCB.
