Embodiment Construction

[0013] Please also refer to Figure 1-2 , a portable electronic device 100 with an NFC antenna, comprising a touch screen 20 and a first printed circuit board 30 and a second printed circuit board 40 arranged on the back of the touch screen 20 . Wherein, the electronic device 100 includes but not limited to a mobile phone or a watch. The touch screen 20 includes a touch area 21 and a non-touch area 22 surrounding the touch area 21 .

[0014] In this embodiment, the first printed circuit board 30 is pasted directly behind the touch screen 20, and the position corresponding to the non-touch area 22 of the touch screen 20 on the first printed circuit board 30 is provided with a parallel NFC antenna 311 and touch sensing circuit 321 . In order to reduce the impact of the touch screen 20 on the performance of the NFC antenna 311 , the material of the touch screen 20 is preferably carbon nanotubes.

[0015] In this embodiment, the second printed circuit board 40 is a flexible pri...

Abstract

A portable electronic device with an NFC antenna comprises a touch screen and a first printed circuit board arranged on the back side of the touch screen. The touch screen comprises a touch area and a non-touch area surrounding the touch area. The upper surface of the first printed circuit board, corresponding to the non-touch area of the touch screen, is imprinted with an NFC antenna and a touch-sensitive circuit side by side. The lower surface of the first circuit board, corresponding to the NFC antenna, is equipped with a shielding layer so as to isolate the NFC antenna from other components arranged below the first circuit board. According to the electronic device, the NFC antenna and the touch-sensitive circuit are printed on the circuit board side by side and are correspondingly adhered to the non-touch area of the touch screen. Thus, the NFC antenna keeps away from a main circuit board of the electronic device; the influence of components on the main circuit board on performance of the NFC antenna is avoided; the space occupied by the NFC antenna in the electronic device is saved; and then the electronic device is allowed to have a thin size.

Description

technical field [0001] The invention relates to the technical field of short-distance wireless communication, in particular to a portable electronic device with an NFC antenna. Background technique [0002] NFC (Near Field Communication, near-field communication technology) is a technology based on portable electronic devices such as mobile phones to achieve short-range wireless communication. In recent years, NFC payment has expanded from only supporting a single business application to supporting multiple applications at the same time, such as integrating multiple application functions for different purposes such as bus cards, credit cards, access cards, bank cards, and membership cards into the same card with NFC On the physical card of the module, it provides great convenience for the daily life of the public. However, the traditional NFC antenna needs to occupy a large space on the PCB board of the electronic device. If the NFC antenna is too close to the components on...
