[0036] Please refer to Figures 3 to 4 The first aspect provided in the embodiments of the present application provides an NFC assembly, which comprises an antenna 10, a chip 30, a display module 20 and a substrate 50. The display module 20 is arranged below the substrate 50. The substrate 50 can be a liquid crystal panel, an OLED panel, a glass panel or a PMMA cover plate, etc. The antenna 10 is arranged at the outer periphery of the display module 20; the chip 30 is electrically connected with the antenna 10. For the convenience of description, in the embodiments of the present application, the display module 20 is arranged on the substrate 50, and the chip 30 is arranged on the substrate 50. Figure 3In the present embodiment, the normal direction of the substrate 50 in the horizontal state is the vertical direction, that is Figure 3 In the present embodiment, the y-axis direction is the vertical direction, and the x-axis direction is the horizontal direction.

[0037] In the prior art as shown in Figure 2 In the prior art, the NFC module 1 is far away from the end of the device in order to avoid metal interference, and thus there is a problem of poor inductive signal. In the present application, the antenna 10 is arranged in any of the above manners, and the antenna 10 is attached to the display module 20 and closely combined with the substrate 50 to form a compact mechanism, so that the antenna 10 is only covered by one layer of substrate 50, and the inductive stability of the antenna 10 to the signal source is ensured without occupying additional space.

[0038] In actual application, when the signal source is close, the antenna 10 can induct and transmit the inductive signal to the chip 30. When the device is close to the signal source for inductive, the signal source is usually located above the device. In the embodiments provided in the present application, the antenna 10 is arranged at the outer periphery of the display module 20, so that the antenna 10 also has inductive capability to the signal source on the side, and the metal in the display module 20 does not interfere with the antenna 10, so that the NFC assembly has the advantages of compact structure, strong inductive stability, no need to modify the display module 20, and wider material selection range of the display module 20.

[0039] As an embodiment, the chip 30 can be connected to the antenna 10 through a flexible printed circuit board 31.

[0040] By using the flexible printed circuit board 31, the chip 30 can be arranged in different areas as needed, for example Figure 4 As shown in the figure, the chip 30 can be arranged in the horizontal direction of the antenna 10, and at this time, the chip 30 can be flush with the antenna 10, or can be located below the side of the antenna 10. In other embodiments, the chip 30 can be folded to the lower side of the display module 20 through the flexible printed circuit board 31.

[0041] In one embodiment, the NFC assembly further comprises a display driving circuit 40; the display driving circuit 40 is electrically connected to the display module 20; and the chip 30 is integrated on the display driving circuit 40.

[0042] In the present embodiment, the chip 30 is arranged on the display driving circuit 40, so that the arrangement position is separated from the arrangement area of the mainboard and does not occupy the space of the mainboard, which is helpful to reduce the occupied area of the mainboard.

[0043] In another embodiment, the NFC assembly further comprises a signal adjusting circuit; the signal adjusting circuit is electrically connected to the antenna 10 and the chip 30; and the signal adjusting circuit is integrated on the display driving circuit 40.

[0044] It should be noted that the chip 30 and the signal conditioning circuit can be packaged on the display driver circuit 40 using precision packaging technology.

[0045] In this embodiment, the signal conditioning circuit is used to condition the NFC signal, which can further reduce material interference in the display module 20 and ensure the stability and effectiveness of the signal.

[0046] In practical applications, signal conditioning circuits can include impedance matching, filtering, signal amplification, and phase adjustment sections.

[0047] The filtering section may include filtering components such as capacitors and inductors to achieve filtering functions and remove interference signals; the signal amplification section mainly consists of amplification components such as transistors and operational amplifiers to amplify the input signal; the phase adjustment section uses phase adjustment components such as phase shifters and RC circuits to change the phase of the signal to achieve phase adjustment.

[0048] In one embodiment, such as Figure 4 As shown, antenna 10 is a quadrilateral frame antenna; antenna 10 is disposed on the outer periphery of display module 20, which enables antenna 10 to increase the sensing range and at the same time reduce the impact of antenna 10 on the display effect of display module 20.

[0049] In one embodiment, a touch sensor wiring area is provided inside the display module 20; the antenna 10 may be disposed on the outer periphery of the touch sensor wiring area.

[0050] In one embodiment, antenna 10 is a transparent antenna. Specifically, antenna 10 is made of a conductive transparent material, such as ITO and indium tin oxide to make an ITO antenna or an indium tin oxide antenna, which can ensure that antenna 10 does not affect the transparency and display effect of display layer 21.

The electronic device provided in this embodiment can be, for example, a mobile phone, tablet, POS machine, PDA, or other terminal electronic device, which integrates touch and NFC functions, improving the integration of the electronic device and the user experience.

[0052] In the NFC component and electronic device provided in this application embodiment, the antenna 10 can be attached to the display module 20, thereby reserving more structural space for the whole device and reducing the size and complexity of the device. Meanwhile, the chip 30 is integrated on the display driver circuit 40, which can reserve more space for component wiring on the motherboard. Furthermore, the NFC component can perform stable and effective sensing without the need for an additional NFC antenna, saving materials and reducing costs.

[0053] The above is only a preferred embodiment of the present application and is not intended to limit the present application.
