In another embodiment, the NFC tag 3 is attached to the left side of the housing body 2, so that the NFC tag 3 can be used by a user with a left hand.

Fig. 2 is a schematic structural diagram of a display screen 1 according to an embodiment of the present application. The display screen 1 comprises a display panel 12, a light guide sheet 13, a reflecting film 14 and a supporting plate 11, wherein the display panel 12, the light guide sheet 13, the reflecting film 14 and the supporting plate 11 are sequentially stacked together. In this embodiment, the display screen 1 is an LCD screen, and the LCD screen is an LCD display screen used in the prior art, and the specific structure of the LCD screen will not be described in detail in this application. Fig. 3 is a schematic diagram of a portion of an electronic device 100 according to an embodiment of the disclosure. In this embodiment, the housing body 2 includes a screen back member 21, and the support plate 11 is fixedly mounted on the screen back member 21 of the housing body 2. For example, the support plate 11 is fixedly mounted on the screen rear surface part 21 of the housing body 2 by screws. Referring to fig. 4, in the present embodiment, the material of the screen back member 21 of the housing body 2 is an aluminum alloy or a magnesium alloy, or a plastic material. In this embodiment, since the NFC information is transmitted through electromagnetic induction coupling of radio frequency in the frequency spectrum, in order to avoid weakening or no signal of the NFC signal strength caused by the absorption and interference of electromagnetic waves by the support plate 11 during the communication with the NFC external device by the NFC tag 3 of the electronic device 100, referring to fig. 3, the support plate 11 is provided with an opening 111, one surface of the screen back component 21 facing the support plate 11 forms the inner surface of the housing body 2, and the NFC tag 3 is attached to the inner surface of the housing body 2 and faces the opening 111 of the support plate 11. The front projection of the aperture 111 on the inner surface overlaps the NFC tag 3. In this way, the interference of the supporting plate 11 to the electromagnetic wave signal received or transmitted by the NFC tag 3 is avoided. In this embodiment, the overlapping of the front projection of the opening 111 on the inner surface with the NFC tag means that the NFC tag 3 is located within the front projection of the opening 111 on the inner surface of the housing body 2, or the projection area formed by the front projection of the opening 111 on the inner surface of the housing body 2 includes or covers the NFC tag 3 attached on the inner surface of the housing body 2.

In this embodiment, the material of the support plate 11 includes iron, nickel, chromium, titanium, aluminum, magnesium, or an alloy thereof. In one embodiment, the supporting plate 11 is a steel sheet, and the steel sheet is a demagnetized steel sheet. The steel sheet is made of stainless steel. In this embodiment, the demagnetization process refers to a process of losing magnetism of an object having magnetism. In one embodiment, demagnetizing treatment may be performed on the support plate 11 by using a demagnetizer. In another embodiment, the support plate 11 may be demagnetized by heating the support plate 11 to a preset temperature (e.g., 770 degrees celsius). In other embodiments, the support plate 11 may be demagnetized by an alternating magnetic field generated by an alternating current welder.

In this embodiment, after the support plate 11 is demagnetized, the openings 111 are punched at preset positions of the support plate 11 according to preset dimensions. For example, referring to fig. 3, an opening 111 is punched at the right side of the support plate 11 in a preset size. To avoid the influence of the support plate 11 on the NFC tag 3, the predetermined size of the opening 111 is larger than the size of the NFC tag 3. In one embodiment, the predetermined size of the opening 111 includes an area of the opening 111. For example, the rectangular opening 111 has a rectangular area defined by the length and width of the opening 111. In another embodiment, the predetermined size of the opening 111 includes a diameter length of the opening 111. For example, the size of the circular opening 111 is the diameter length of the opening 111. In an embodiment, the predetermined dimension of the opening 111 may be a dimension formed by expanding 5mm from the peripheral side of the NFC tag 3. In an embodiment, the shape of the opening 111 matches the shape of the NFC tag 3. In this embodiment, the shape of the opening 111 matches the shape of the NFC tag 3 means that the shape of the opening 111 is the same as or similar to the shape of the NFC tag 3. In an embodiment, the shape of the opening 11 is designed according to the shape of the NFC tag 3. For example, if the NFC tag 3 is rectangular in shape, the shape of the aperture 11 may be die cut into a rectangular shape.

It should be noted that, the NFC tag 3 is flatly attached to the housing body 2, so that instability of electromagnetic wave signals when the NFC external device recognizes the NFC tag 3 in the recognition area 10 of the display screen 1 due to wrinkling of the NFC tag 3 is avoided. For the purpose of flatly attaching the NFC tag 3 to the housing body 2, the NFC tag 3 may be made of polyvinyl chloride (Polyvinyl chloride, PVC) or polyethylene terephthalate (polyethylene terephthalate, PET). In this embodiment, the NFC tag 3 does not perform the appearance ink processing of the pattern prompt, for example, the NFC tag 3 does not perform the appearance ink processing of the pattern prompt of the print identification character, so as to reduce the design cost of the NFC tag 3.

Fig. 5 is a schematic structural diagram of a display screen 1 according to another embodiment of the present application. The display screen 1 comprises a display panel 12. The display panel 12 is mounted on the housing body 2. For example, the display panel 12 is mounted on the housing body by means of adhesion. The NFC tag 3 is attached to the inner surface of the housing body 2 and faces the display panel 12. In this way, the electronic apparatus 100 is ensured to be neat in appearance. In this embodiment, the display screen 1 is an OLED display screen.

Referring to fig. 6, after the NFC external device is placed in the NFC identification area of the NFC tag 3, the electronic device 100 may automatically identify the NFC external device and establish a Wifi or bluetooth direct connection channel, so as to implement signal connection between the electronic device 100 and the NFC external device. Referring to table one, a table of NFC recognition ranges when different types of mobile phones and electronic devices 100 perform NFC recognition is shown. The NFC identification range refers to a distance range in which the NFC external device can perform NFC connection with the electronic device 100. For example, in the following relationship, the NFC recognition range of the NFC recognition between the model 1 mobile phone and the electronic device 100 is 0mm-7mm, and the NFC recognition range of the NFC recognition between the model 2 mobile phone and the electronic device 100 is 0mm-13mm. In this embodiment, the electronic device 100 may be a notebook computer, a tablet, a display screen, or the like. The NFC external device can be a mobile phone, a tablet, a wearable device and the like.

In step S703, device information of the NFC external device is acquired according to the connection request and a communication connection is established with the NFC external device.

In this embodiment, the connection request carries device information of the mobile phone. The PC responds to the connection request, acquires the type information of the mobile phone from the connection request, and sends a reply signal to the mobile phone. After receiving the reply signal sent by the PC, the mobile phone establishes communication connection with the PC. For example, after receiving the reply signal sent by the PC, the mobile phone establishes communication connection with the PC through a WiFi communication mode, a bluetooth communication mode or an NFC communication mode. It should be noted that, the process of establishing communication connection between the mobile phone and the PC through the WiFi communication mode, the bluetooth communication mode or the NFC communication mode is the prior art, and specific contents of establishing the communication connection process between the mobile phone and the PC will not be described in detail here. Step S704, displaying the screen content of the NFC external device in the second area of the display screen 1 according to the device information of the NFC external device.

Referring to fig. 8c, the pc acquires the screen content of the mobile phone, and displays the screen content of the mobile phone in the second area 82 of the display screen 1 according to the device information of the mobile phone.

Referring to fig. 9, a flowchart of a method for determining device information of an NFC external device in an embodiment of the present application is shown. In this embodiment, the connection request includes NFC tag identity Information (ID) of the NFC external device. The NFC tag identity information is a character string consisting of numbers or letters and is used for identifying the NFC tag. The method for determining the device information of the NFC external device comprises the following steps.

Step S901 extracts the NFC tag ID from the connection request.

In step S902, device information of the NFC external device is obtained according to the NFC tag ID.

It should be noted that, the device information of the NFC external device includes information such as a type of the NFC external device, a model number of the NFC external device, a size of the NFC external device, a manufacturer of the NFC external device, and the like, and when the manufacturer of the NFC external device produces the NFC external device (such as a mobile phone), the NFC tag ID of the NFC external device is already bound with the model number of the external device, the manufacturer, and the like. The NFC tag ID of the NFC external device and the device information of the NFC external device are stored in the database in advance. After extracting the NFC tag ID of the NFC external device from the connection request, the electronic device 100 queries in a database according to the NFC tag ID of the NFC external device, and determines device information corresponding to the NFC tag ID of the NFC external device. In this embodiment, the database includes a correspondence between NFC tag IDs of the NFC external devices and device information of the NFC external devices, where device type information of different NFC external devices corresponds to different NFC tag IDs. In an embodiment, the database is stored in a local memory of the electronic device 100, and the electronic device 100 may obtain the data of the database from the local memory. In another embodiment, the database is stored in a remote server from which the electronic device 100 may retrieve the database data.

Referring to fig. 10, a flowchart of a method for determining device information of an NFC external device in another embodiment of the present application is shown. The method for determining the device information of the NFC external device comprises the following steps.

In step S1001, the electromagnetic wave signal characteristics of the NFC external device are detected.

Step S1002, determining device information of the NFC external device according to the electromagnetic wave signal feature.

In this embodiment, since there are differences (such as differences in the number and size of coils) between NFC coils in NFC tags of different NFC external devices, there are differences between electromagnetic wave signal characteristics (such as electromagnetic wave signal intensities) sent by the NFC external devices to the electronic device 100. The electronic device 100 determines device information corresponding to the acquired electromagnetic wave signal characteristics by looking up a database according to the acquired electromagnetic wave signal characteristics.
