Problems solved by technology

Due to the limited internal space of smart electronic devices and the limited thickness of ferrite material substrates, it is difficult to further improve near-field communication (NFC) antennas and wireless charging antennas in a limited space.
[0004] At the same time, the connection between the conventional near-field communication (NFC) antenna module and the wireless charging antenna module needs to use metal shrapnel and other connectors between the main printed circuit board (PCB), because the cloth on the main printed circuit board (PCB) Board space is tight, and the location of the metal shrapnel is limited, which also brings difficulties to engineering design

Abstract

The invention discloses an electronic device integrating a near-field communication NFC antenna, wireless charging and a display screen. The electronic device comprises a near-field communication NFCantenna and/or wireless charging antenna and display screen integrated assembly, a main printed circuit board PCB and a battery. The near-field communication NFC antenna and/or wireless charging antenna and display screen integrated assembly comprises a display screen assembly and a near-field communication NFC antenna and/or wireless charging antenna assembly. The display screen assembly comprises a flexible printed circuit board FPC and a display module. The flexible printed circuit board FPC comprises an area for providing a driving IC or a touch control IC, a connector for interconnectingwith the main printed circuit board PCB and a protruding portion area. The near-field communication NFC antenna and/or wireless charging antenna assembly is arranged on the protruding portion area ofthe flexible printed circuit board FPC. The electronic device can effectively utilize the space of the device, improves integration level, reduces metal spring assemblies, reduces assembly link and saves cost.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device integrating a near-field communication NFC antenna, wireless charging and a display screen. Background technique [0002] At present, with the development of wireless communication technology and mobile terminals, the functions of smart electronic devices such as smartphones, tablet computers, and e-books are becoming more and more abundant, and more and more products integrate NFC (Near Field Communication) and wireless charging. (Wireless Charging) function, widely used in wireless payment, data transmission and other fields. Near Field Communication (NFC) technology uses a frequency band of 13.56MHz for two-way point-to-point non-contact near-field wireless communication between terminals. Wireless charging is non-contact charging by placing smart electronic devices on or near a charger. Compared with the traditional wired charging mode, wireless charging can char...
