Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0023] Currently, near-field communication (NFC) sensors for display devices are typically located on the main body of the display device, rather than on the screen. This not only forces users to move closer to the main body of the display device to use the NFC sensors, reducing the convenience of the display device, but also increases its size, preventing further improvements in the thinness and lightness of the display device.

[0024] Please see Figure 1 , Figure 1 This is a schematic structural diagram of a display device provided in an embodiment of this application. Figure 1 As shown, the display device 11 may include a device body 111 and a screen 112 mounted on the device body. Furthermore, the display device 11 may also include a near-field communication sensor 113 mounted on the screen 112.

[0025] The display device 11 can communicate with external devices via a near-field communication sensor 113. For example, external devices may include, but are not limited to, electronic devices such as mobile phones and computers.

[0026] Specifically, the near-field communication sensor 113 can be used to acquire data sent by an external device and can send the data sent by the external device to the control module of the display device 11; the near-field communication sensor 113 can also be used to acquire data sent by the control module of the display device 11 and can send the data sent by the control module of the display device 11 to an external device.

[0027] The near-field communication sensing device 113 may include a plurality of near-field communication sensing antennas 1131.

[0028] The display device 11 may also include a near-field communication reader 114, and each near-field communication sensing antenna 1131 may be connected in series, and the near-field communication sensing antenna 1131 at the end of each near-field communication sensing antenna 1131 may be connected to the near-field communication reader 114.

[0029] Each near-field communication sensing antenna 1131 can be used to acquire data sent by an external device and can send the data sent by the external device to the near-field communication reader 114 of the display device 11. Each near-field communication sensing antenna 1131 can also be used to acquire data sent by the near-field communication reader 114 and can send the data sent by the near-field communication reader 114 to an external device.

[0030] In one possible implementation, the display device 11 may also include a control module 115. The control module 115 may be connected to the near-field communication reader 114.

[0031] The near-field communication reader 114 can be specifically used to receive data sent by each near-field communication induction antenna 1131 and send the data sent by each near-field communication induction antenna 1131 to the control module 115; the near-field communication reader 114 can also be specifically used to receive data sent by the control module 115 and send the data sent by the control module 115 to each near-field communication induction antenna 1131.

[0032] The control module 115 can be specifically used to receive data sent by the near-field communication reader 114 and to send data to the near-field communication reader 114. The near-field communication reader 114 is also used to send data to the control module 115 and to receive data sent by the control module 115.

[0033] For example, when near-field communication sensing antenna A needs to send data to near-field communication reader 114, near-field communication sensing antenna A can first send data to near-field communication sensing antenna B, instructing near-field communication sensing antenna B to send data to near-field communication sensing antenna C, and instructing near-field communication sensing antenna C to send data to near-field communication sensing antenna D, and so on, until the data is sent to the end near-field communication sensing antenna R. After receiving the data, the end near-field communication sensing antenna R will send the data to near-field communication reader 114, thus completing the process of near-field communication sensing antenna A sending data to near-field communication reader 114.

[0034] Similarly, when the near-field communication sensing antennas 1131 are connected in series, the near-field communication reader 114 that needs to send data to the near-field communication sensing antenna 1131 can send data to the near-field communication reader 114 through other near-field communication sensing antennas 1131, including the near-field communication sensing antenna 1131 at the end.

[0035] For example, when the near-field communication reader 114 needs to send data to the near-field communication sensing antenna A, the near-field communication reader 114 can first send the data to the end near-field communication sensing antenna R to instruct the near-field communication sensing antenna R to send the data to the near-field communication sensing antenna Q, and instruct the near-field communication sensing antenna Q to send the data to the near-field communication sensing antenna P, and so on, until the data is sent to the near-field communication sensing antenna A, thereby completing the process of the near-field communication reader 114 sending data to the near-field communication sensing antenna A.

[0036] When the near-field communication reader 114 receives data sent by any near-field communication induction antenna 1131, it can send the data to the control module 115. The control module 115 can determine the near-field communication induction antenna 1131 to send the data based on the electromagnetic wave parameter characteristics of the received data.

[0037] In practical applications, each near-field communication induction antenna 1131 can be made of nano-silver or metallic ink.

[0038] In one possible implementation, the screen 111 may include a glass substrate and / or tempered glass. Accordingly, each near-field communication sensing antenna 1131 may be disposed on the glass substrate and / or tempered glass.

[0039] In another possible implementation, the screen 111 may include a thin film. Based on this, the various near-field communication sensing antennas 1131 can be disposed on the thin film.

[0040] In one possible implementation, screen 112 may include several preset areas, the number of which is the same as the number of near-field communication (NFC) sensors 113. Each NFC antenna 1131 in any NFC sensor 113 is disposed in the corresponding preset area of ​​the NFC sensor 113. In practical applications, the preset areas of the NFC sensors 113 on screen 111 can be set according to actual needs. For example, the NFC sensors 113 can be disposed in all areas of screen 111, in which case the user can use the NFC sensors 113 in the vicinity of the entire screen 1111; for example, the NFC sensors 113 can be disposed in several preset areas of screen 111, in which case the user can use the NFC sensors 113 in the vicinity of these preset areas.

[0041] Please see Figure 2 , Figure 2 This is a schematic structural diagram of a display device provided for another embodiment of this application.

[0042] Figure 2 The display device 11 shown is Figure 1The difference between the display device 11 shown is that the near-field communication sensing antennas 1131 are arranged in a two-dimensional matrix, with all near-field communication sensing antennas 1131 in each first direction connected in series and all near-field communication sensing antennas 1131 in each second direction connected in series.

[0043] In one possible implementation, the display device 11 may further include a first antenna signal switcher 116 and a second antenna signal switcher 117.

[0044] The first antenna signal switcher 116 is connected to the end of the near-field communication induction antenna 1131 in each of the near-field communication induction antennas 1131 in each of the first directions; the second antenna signal switcher 117 is connected to the end of the near-field communication induction antenna 1131 in each of the second directions.

[0045] In addition, the first antenna signal switcher 116 and the second antenna signal switcher 117 are both connected to the near-field communication reader 114.

[0046] When the near-field communication sensing antennas 1131 are arranged in a two-dimensional matrix, the near-field communication sensing antennas 1131 that need to send data to the near-field communication reader 114 can first send the data to the near-field communication sensing antennas 1131 at the end of the first direction and the near-field communication sensing antennas 1131 at the end of the second direction through other near-field communication sensing antennas 1131. This instructs the near-field communication sensing antennas 1131 at the end of the first direction to send the data to the first antenna signal switcher 116, and instructs the near-field communication sensing antennas 1131 at the end of the second direction to send the data to the second antenna signal switcher 117. The first antenna signal switcher 116 and the second antenna signal switcher 117 are then instructed to send the data to the near-field communication reader 114, thereby realizing the transmission of data to the near-field communication reader 114.

[0047] For example, when the near-field communication sensing antenna H needs to send data to the near-field communication reader 114, the near-field communication sensing antenna H can send data to the near-field communication sensing antenna G to instruct the near-field communication sensing antenna G to send data to the first antenna signal switcher 116, and instruct the first antenna signal switcher 116 to send data to the near-field communication reader 114. In addition, the near-field communication sensing antenna H can send data to the near-field communication sensing antenna E to instruct the near-field communication sensing antenna E to send data to the second antenna signal switcher 117, and instruct the second antenna signal switcher 117 to send data to the near-field communication reader 114, thereby realizing the transmission of data sent by the near-field communication sensing antenna H to the near-field communication reader 114.

[0048] Similarly, when the near-field communication sensing antennas 1131 are arranged in a two-dimensional matrix, the near-field communication reader 114, which needs to send data to the near-field communication sensing antenna 1131 of the target, can first send the data to the first antenna signal switcher 116 and the second antenna signal switcher 117 respectively, so as to instruct the first antenna signal switcher 116 to send the data to the near-field communication sensing antenna 1131 at the end of the first direction, and instruct the second antenna signal switcher 117 to send the data to the near-field communication sensing antenna 1131 at the end of the second direction, and instruct the near-field communication sensing antenna 1131 at the end of the first direction to send the data to the near-field communication sensing antenna 1131 of the target through other near-field communication sensing antennas 1131, and instruct the near-field communication sensing antenna 1131 at the end of the second direction to send the data to the near-field communication sensing antenna 1131 of the target through other near-field communication sensing antennas 1131, thereby realizing the transmission of the data sent by the near-field communication reader 114 to the near-field communication sensing antenna of the target.

[0049] For example, when the near-field communication reader 114 needs to send data to the near-field communication sensing antenna H, the near-field communication reader 114 can first send the data to the first antenna signal switcher 116 and the second antenna signal switcher 117 respectively, so as to instruct the first antenna signal switcher 116 to send the data to the near-field communication sensing antenna G, and instruct the near-field communication sensing antenna G to send the data to the near-field communication sensing antenna H, and instruct the second antenna signal switcher 117 to send the data to the near-field communication sensing antenna E, and also instruct the near-field communication sensing antenna E to send the data to the near-field communication sensing antenna H, thereby realizing the transmission of the data sent by the near-field communication reader 114 to the near-field communication sensing antenna H.

[0050] In practical applications, the first antenna signal switcher 116 can acquire data transmitted by each near-field communication sensing antenna 1131 in a first direction at preset time intervals. For example, the first antenna signal switcher 116 can first acquire data transmitted by near-field communication sensing antennas A to F. After a preset time, the first antenna signal switcher 116 can acquire data transmitted by near-field communication sensing antennas G to L. After a preset time, the first antenna signal switcher 116 can acquire data transmitted by near-field communication sensing antennas M to R. After a preset time, the first antenna signal switcher 116 can acquire data transmitted by near-field communication sensing antennas A to F, and so on.

[0051] In practical applications, the second antenna signal switcher 117 can acquire data transmitted by each near-field communication induction antenna 1131 in a second direction at preset intervals. For example, the second antenna signal switcher 117 can first acquire data transmitted by near-field communication induction antennas A, L, and M. After a preset time, the second antenna signal switcher 117 can acquire data transmitted by near-field communication induction antennas B, K, and N. After a preset time, the second antenna signal switcher 117 can acquire data transmitted by near-field communication induction antennas C, J, and O. After a preset time, the second antenna signal switcher 117 can acquire data transmitted by near-field communication induction antennas D, I, and P. After a preset time, the second antenna signal switcher 117 can acquire data transmitted by near-field communication induction antennas E, H, and Q. After a preset time, the second antenna signal switcher 117 can acquire data transmitted by near-field communication induction antennas F, H, and R.

[0052] The first antenna signal switcher 116 and the second antenna signal switcher 117 can also transmit data to the control module 115 via the near-field communication reader / writer 114. Based on this, the control module 115 can combine the signals transmitted by the first antenna signal switcher 116 and the second antenna signal switcher 117 to determine the near-field communication induction antenna 1131 for transmitting data.

The display device also includes a near-field communication sensing device installed at the screen position. The display device communicates with external devices through the near-field communication sensing device. The near-field communication sensing device includes several near-field communication sensing antennas, and the display device also includes a near-field communication reader / writer. Each near-field communication sensing antenna is connected in series, and the near-field communication sensing antenna at the end of each near-field communication sensing antenna is connected to the near-field communication reader / writer. The near-field communication sensing device in the display device provided in this application is located at the screen position of the display device. Therefore, the user only needs to be near the screen of the display device to use the near-field communication sensing device, so that the user does not need to move to the vicinity of the device body to use the near-field communication sensing device, thus improving the convenience of the display device. For example, in some scenarios where presentations are given through a display device, the user usually needs to stand near the screen of the display device.
