[0042] With the development of display technology and wireless communication technology, the requirements for the communication performance of wireless communication devices are becoming increasingly higher. Intelligent Reflecting Surface (IRS) is an important communication design that has received widespread attention and research investment. This is because it can change the direction and number of reflected beams incident from wireless signal sources by regulating the amplitude and phase of the electrical signals on multiple reflective units on this surface (that is, by changing the electrical load of the reflective units). For example, this reflected beam can be maintained as one or divided into multiple reflected beams and steered to focus on the direction of one or more communication targets, thereby significantly improving the quality of wireless communication. The IRS can be located on the interior or exterior walls of a building. In addition, the antenna is also an important functional component of a wireless communication device for transmitting wireless signals.

[0043] An IRS typically consists of a three-layer structure. The top layer consists of reflective elements, which are conductive structures used to reflect wireless signals. Below the reflective elements is a metal plate, such as copper, that blocks and reflects wireless signals. A control circuit board is located on the side of the metal plate facing away from the reflective elements. The control circuitry on this board is connected to the reflective elements and is used to control the signal amplitude and phase of each reflective element, thereby controlling the direction and number of reflected beams. These three layers are not visually transparent to the human eye, making the IRS also not visually transparent.

[0044] In order to improve the communication performance of the wireless communication device, the present application integrates an IRS into the wireless communication device and multiplexes the reflection unit in the IRS and the antenna unit in the antenna to improve the wireless communication performance of the wireless communication device.

[0045] In order to solve the above problems, the present application is proposed. In order to better understand the present application, the display panel, wireless communication device and multi-functional component of the embodiments of the present application are described in detail with reference to Figures 1 to 31 below.

[0046] Please refer to Figures 1 to 3. Figure 1 is a schematic structural diagram of a display panel 10 provided in an embodiment of the present application. Figure 2 is a cross-sectional view taken at AA in Figure 1. Figure 3 is a cross-sectional view taken at BB in Figure 1.

[0047] As shown in Figures 1 to 3, the display panel 10 includes: a substrate 11, a functional layer 100, a shielding layer 200, and an antenna assembly 900. The functional layer 100 is provided on the substrate 11 and includes a multi-function unit 120, which is used to reflect wireless signals; the shielding layer 200 is provided on the side of the multi-function unit 120 facing the substrate 11; the antenna assembly 900 includes a non-millimeter wave antenna unit 920 and a millimeter wave antenna unit 910, and the multi-function unit 120 is multiplexed as a part of the millimeter wave antenna unit 910 and the non-millimeter wave antenna unit 920. The position of the non-millimeter wave antenna unit 920 is indicated by a dotted box in Figure 1, and the dotted box does not constitute a limitation on the structure of the display panel 10 in the embodiment of the present application.

[0048] In the display panel 10 provided in the embodiment of the present application, the display panel 10 includes a substrate 11, a functional layer 100, a shielding layer 200, and an antenna assembly 900. The functional layer 100 includes a multi-function unit 120, which can reflect wireless signals, thereby improving the wireless performance of the display panel 10; the shielding layer 200 is arranged on the side of the functional layer 100 away from the display surface of the display panel 10, and is used to block wireless signals incident from the display surface. The antenna assembly 900 includes a millimeter wave antenna unit 910 and a non-millimeter wave antenna unit 920, so that the display panel 10 can be used to transmit millimeter wave antenna signals and non-millimeter wave antenna signals, which can further enrich the wireless communication function of the display panel 10. In addition, the multi-function unit 120 is multiplexed as a part of the millimeter wave antenna unit 910 and the non-millimeter wave antenna unit 920, which can simplify the structure of the display panel 10.

[0049] Optionally, the shielding layer 200 serves as a metal plate in the above-mentioned IRS to shield and reflect wireless signals.

[0050] The multiplexing of the multi-function unit 120 as a part of the millimeter wave antenna unit 910 and the non-millimeter wave antenna unit 920 means that the multi-function unit 120 is multiplexed as the millimeter wave antenna unit 910 and the multi-function unit 120 is also multiplexed as a part of the non-millimeter wave antenna unit 920 .

[0051] Optionally, the multi-function unit 120 is multiplexed into the millimeter wave antenna unit 910, and the multi-function unit 120 can also be used to transmit millimeter wave antenna signals.

[0052] Optionally, the multiplexing of the multi-function unit 120 as part of the non-millimeter-wave antenna unit 920 may be: one multi-function unit 120 is multiplexed as part of the non-millimeter-wave antenna unit 920; or at least two adjacent multi-function units 120 are connected via a connecting signal line 130 and multiplexed as part of the non-millimeter-wave antenna unit 920; or at least two adjacent multi-function units 120 are connected via a connecting signal line 130 and multiplexed as the non-millimeter-wave antenna unit 920. Multiplexing the multi-function unit 120 as part of the non-millimeter-wave antenna unit 920 means that the multi-function unit 120 can have the functions of the non-millimeter-wave antenna unit 920 and be used to transmit and receive non-millimeter-wave wireless signals.

[0053] Optionally, when at least two adjacent multi-function units 120 are connected via a connecting signal line 130 and multiplexed as part of a non-millimeter wave antenna unit 920, the at least two adjacent multi-function units 120 are connected in series and / or in parallel with each other via a connecting signal line 130 and multiplexed as part of a non-millimeter wave antenna unit 920.

[0054] Optionally, the multi-function unit 120 multiplexed as the millimeter wave antenna unit 910 and the multi-function unit 120 multiplexed as a part of the non-millimeter wave antenna unit 920 may be the same multi-function unit 120 or different multi-function units 120 .

[0055] Optionally, the millimeter wave antenna unit 910 is the radiating portion of the millimeter wave antenna, or the millimeter wave antenna unit 910 includes a millimeter wave feed portion and a millimeter wave radiating portion, and the multi-function unit 120 can be multiplexed as the millimeter wave radiating portion. Optionally, the non-millimeter wave antenna unit 920 is the radiating portion of the non-millimeter wave antenna, or the non-millimeter wave antenna unit 920 includes a non-millimeter wave feed portion and a non-millimeter wave radiating portion, and the multi-function unit 120 is multiplexed as a part of the non-millimeter wave radiating portion.

[0056] Optionally, when the display panel 10 is used in a wireless communication device, and the wireless communication device includes a control component 600, and the control component 600 includes a control circuit 610 and a radio frequency circuit 620, the multi-function unit 120 and the control circuit 610 are electrically connected to each other, so that the control circuit 610 changes the electrical load of the multi-function unit 120. The radio frequency circuit 620 includes a millimeter-wave radio frequency circuit 621 and a non-millimeter-wave radio frequency circuit 622. The millimeter-wave radio frequency circuit 621 is connected to at least one multi-function unit 120 so that the multi-function unit 120 is multiplexed into a millimeter-wave antenna unit 910 and used to transmit millimeter-wave antenna signals. The non-millimeter-wave radio frequency circuit 622 is connected to at least one multi-function unit 120 so that the multi-function unit 120 is multiplexed into a portion of the non-millimeter-wave antenna unit 920 and used to transmit non-millimeter-wave antenna signals. Optionally, the control component 600 can also be provided in the display panel 10, that is, the display panel 10 includes the aforementioned control component 600.

[0057] In some optional embodiments, the same multi-function unit 120 is multiplexed as part of the millimeter wave antenna unit 910 and the non-millimeter wave antenna unit 920, that is, the same multi-function unit 120 can be used to transmit both millimeter wave antenna signals and non-millimeter wave antenna signals, which can further simplify the structure of the display panel 10.

[0058] In other embodiments, at least one of the multiple multi-function units 120 is multiplexed into the millimeter-wave antenna unit 910, and at least one of the remaining multi-function units 120 is multiplexed into a portion of the non-millimeter-wave antenna unit 920. That is, the multi-function unit 120 multiplexed into the millimeter-wave antenna unit 910 and the multi-function unit 120 multiplexed into a portion of the non-millimeter-wave antenna unit 920 are different multi-function units 120, which can improve mutual crosstalk between signals.

[0059] Optionally, as shown in FIG4 , the number of non-millimeter wave antenna units 920 and / or millimeter wave antenna units 910 may be multiple to improve the ability of the display panel 10 to transmit non-millimeter wave signals and / or millimeter wave signals. Alternatively, as shown in FIG1 and FIG5 , the number of non-millimeter wave antenna units 920 may be one. FIG5 differs from FIG1 in that the number of multi-function units 120 included in the non-millimeter wave antenna unit 920 is different.

[0060] Optionally, the display panel 10 includes a control line 300 and a multi-function unit 120, wherein the control line 300 connects the control circuit 610 and the multi-function unit 120. As shown in Figures 1 to 3, the control line 300 and the multi-function unit 120 can be arranged in the same layer. Alternatively, as shown in Figures 6 and 7, the control line 300 and the multi-function unit 120 can be arranged in different layers. In Figures 6 and 7, the multi-function unit 120 and the reflective unit 110 are arranged in the same layer. Therefore, when the control line 300 and the multi-function unit 120 are arranged in different layers, as shown in Figure 7, the control line 300 and the reflective unit 110 are arranged in different layers.

[0061] As shown in Figures 6 to 8, the same multi-function unit 120 is connected to both the control circuit 610 and the millimeter-wave RF circuit 621 and the non-millimeter-wave RF circuit 622, so that the same multi-function unit 120 can be multiplexed as a part of the reflecting surface, the millimeter-wave antenna unit 910 and the non-millimeter-wave antenna unit 920.

[0062] In some optional embodiments, as shown in Figure 9, the display panel 10 also includes a multi-function control feeder 820, one end of the multi-function control feeder 820 is connected to the multi-function unit 120, and the other end of the multi-function control feeder 820 is used to connect the control circuit 610 and the radio frequency circuit 620, so that the control circuit 610 and the radio frequency circuit 620 can transmit control signals to the multi-function unit 120 through the multi-function control feeder 820.

[0063] In these optional embodiments, the multi-function control feed line 820 can be used to connect the control circuit 610 and the multi-function unit 120 , and can also be used to connect the RF circuit 620 and the multi-function unit 120 , which can further simplify the structure of the display panel 10 .

[0064] When the multi-function unit 120 is multiplexed as the millimeter-wave antenna unit 910, the other end of the multi-function control feeder 820 is connected to the millimeter-wave RF circuit 621. When the multi-function unit 120 is multiplexed as a non-millimeter-wave antenna unit 920, the other end of the multi-function control feeder 820 is connected to the non-millimeter-wave RF circuit 622. When the same multi-function unit 120 is multiplexed as part of the millimeter-wave antenna unit 910 and the non-millimeter-wave antenna unit 920, the other end of the multi-function control feeder 820 is connected to the millimeter-wave RF circuit 621 and the non-millimeter-wave RF circuit 622.

[0065] Optionally, as shown in Figures 6 to 8, the display panel 10 further includes a radio frequency line 810, which connects the radio frequency circuit 620 and the multi-function unit 120. The radio frequency line 810 includes a millimeter wave feed line 811 and a non-millimeter wave feed line 812. The multi-function control feed line 820 can be multiplexed into at least two of the millimeter wave feed line 811, the non-millimeter wave feed line 812, and the control line 300.

[0066] As shown in Figures 9 and 10, the multi-function control feeder 820 is multiplexed into a millimeter-wave feeder 811 and a control line 300. The display panel 10 includes a non-millimeter-wave feeder 812 and a multi-function control feeder 820. The non-millimeter-wave feeder 812 connects the non-millimeter-wave RF circuit 622 and the multi-function unit 120, and the multi-function control feeder 820 connects the multi-function unit 120 with the millimeter-wave RF circuit 621 and the control circuit 610. Alternatively, as shown in Figure 11, the multi-function control feeder 820 is multiplexed into a millimeter-wave feeder 811 and a non-millimeter-wave feeder 812. The display panel 10 includes a control line 300 and a multi-function control feeder 820. The control line 300 connects the control circuit 610 and the multi-function unit 120, and the multi-function control feeder 820 connects the multi-function unit 120 with the millimeter-wave RF circuit 621 and the non-millimeter-wave RF circuit 622. 12 and 13 , the multi-function control feeder 820 is multiplexed into the millimeter wave feeder 811, the non-millimeter wave feeder 812, and the control line 300. The multi-function control feeder 820 connects the multi-function unit 120 with the millimeter wave RF circuit 621, the non-millimeter wave RF circuit 622, and the control circuit 610.

[0067] In some optional embodiments, as shown in Figures 1 to 13, more than two multi-function units 120 are interconnected through a connecting signal line 130 and multiplexed into a non-millimeter wave antenna unit 920, that is, the non-millimeter wave antenna unit 920 is formed by multiplexing more than two multi-function units 120, which can further simplify the structure of the non-millimeter wave antenna unit 920.

[0068] Optionally, at least one of the two or more multi-function units 120 multiplexed into the non-millimeter wave antenna unit 920 is multiplexed into the millimeter wave antenna unit 910 to further simplify the structure of the display panel 10 .

[0069] In any of the above embodiments, there are various ways to set up the connecting signal line 130. For example, the connecting signal line 130 may include one conductor, or the connecting signal line 130 may include multiple conductors arranged side by side, or the connecting signal line 130 may include multiple conductors arranged side by side and a bridge line connecting the conductors arranged side by side.

[0070] When the interconnected multi-function units 120 that are multiplexed into non-millimeter-wave antenna units 920 are also multiplexed into millimeter-wave antenna units 910, the line width of at least a portion of the connecting signal line 130 is no greater than the width of the millimeter-wave antenna unit 910. Optionally, the millimeter-wave antenna unit 910 includes a millimeter-wave conductive line, and the line width of at least a portion of the connecting signal line 130 is no greater than the width of the millimeter-wave conductive line within the millimeter-wave antenna unit 910.

[0071] When the millimeter wave antenna unit 910 is block-shaped, the millimeter wave antenna unit 910 can be understood as including a millimeter wave conductor; when the millimeter wave antenna unit 910 includes multiple millimeter wave conductors, the line width of at least a portion of the area connecting the signal line 130 is smaller than the width of the millimeter wave antenna unit 910, which means that the line width of at least a portion of the area connecting the signal line 130 is smaller than the sum of the widths of the multiple millimeter wave conductors in the millimeter wave antenna unit 910.

[0072] In the embodiment of the present application, when the line width of at least a portion of the connecting signal line 130 is no greater than the width of the millimeter-wave conductor within the millimeter-wave antenna unit 910, the line width of the connecting signal line 130 is relatively narrow, and therefore the connecting signal line 130 has a relatively high impedance. Therefore, the connecting signal line 130 has a relatively good filtering and blocking effect on currents in the millimeter-wave band. However, the connecting signal line 130 can also have a relatively good passing effect on non-millimeter-wave currents. Therefore, in the embodiment of the present application, non-millimeter-wave currents can pass through the connecting signal line 130 relatively well, while millimeter-wave currents are blocked by the connecting signal line 130.

[0073] The millimeter wave current refers to the current corresponding to the millimeter wave band wireless signal frequency band received and transmitted by the millimeter wave antenna unit 910 , and the non-millimeter wave current refers to the current corresponding to the non-millimeter wave band wireless signal frequency band received and transmitted by the non-millimeter wave antenna unit 920 .

[0074] Optionally, when the width of at least a portion of the connecting signal line 130 is no greater than the width of the millimeter-wave antenna unit 910, as shown in FIG1 , when the connecting signal line 130 comprises a single conductor, the width of a single conductor within the connecting signal line 130 is no greater than the sum of the widths of the millimeter-wave conductors in the millimeter-wave antenna unit 910 extending in the same direction as the connecting signal line 130. In other embodiments, when the connecting signal line 130 comprises multiple conductors, the sum of the widths of the multiple conductors within the connecting signal line 130 is no greater than the sum of the widths of the millimeter-wave conductors in the millimeter-wave antenna unit 910 extending in the same direction as the connecting signal line 130. As shown in FIG1 , when the first direction X and the second direction Y are perpendicular and the connecting signal line 130 extends along the second direction Y, the width of the connecting signal line 130 is in the first direction X, and the width of the millimeter-wave conductor is also in the first direction X.

[0075] In an embodiment of the present application, when the sum of the widths of the wires in the connecting signal line 130 is not greater than the sum of the widths of the millimeter-wave wires in the millimeter-wave antenna unit 910 that extend in the same direction as the connecting signal line 130, that is, the width of the connecting signal line 130 is narrower, the connecting signal line 130 has a higher impedance, and therefore the connecting signal line 130 has a better filtering and blocking effect on currents in the millimeter-wave band.

[0076] The signal lines 130 can be configured in a variety of ways. The signal lines 130 can be straight, meaning they extend in the same direction. Alternatively, they can be zigzag, meaning they extend along a meandering path. Alternatively, they can be curved. Alternatively, the signal lines 130 can be a combination of at least two of a straight line, a zigzag, and an arc.

[0077] In some optional embodiments, as shown in Figures 9 and 13, at least one non-millimeter wave antenna unit 920 is connected to a first signal voltage 140. The first signal voltage 140 may be a negative voltage signal, or the first signal voltage 140 may be a ground voltage signal.

[0078] Optionally, the non-millimeter wave antenna unit 920 can be connected to the first signal voltage 140 through a multiplexed multi-function unit 120, that is, at least one multi-function unit 120 multiplexed as a non-millimeter wave antenna unit 920 is connected to the first signal voltage 140, or the non-millimeter wave antenna unit 920 can be connected to the first signal voltage 140 through a connecting signal line 130.

[0079] Optionally, when there are multiple non-millimeter wave antenna units 920 , at least one non-millimeter wave antenna unit 920 only needs to be connected to the first signal voltage 140 .

[0080] Optionally, in any of the above embodiments, the millimeter wave antenna unit 910 is used to transmit and receive millimeter wave band wireless signals, that is, to receive and / or transmit millimeter wave band wireless signals. Similarly, the non-millimeter wave antenna unit 920 is used to transmit and receive non-millimeter wave band wireless signals, that is, to receive and / or transmit non-millimeter wave band wireless signals.

[0081] Two or more millimeter-wave antenna units 910 are spaced apart around the perimeter of the display panel 10, with the millimeter-wave antenna units 910 located at different locations on the display panel 10. When a user uses different gestures to operate the display panel 10, one of the millimeter-wave antenna units 910 is always in a position that is not blocked by the user. This improves the stability of the millimeter-wave antenna units 910 in transmitting and receiving wireless signals, thereby better ensuring the user's wireless experience.

[0082] Optionally, the non-millimeter wave antenna units 920 are spaced around the periphery of the display panel 10, and the non-millimeter wave antenna units 920 are distributed at different positions on the display panel 10. When the user uses different gestures to operate the display panel 10, the non-millimeter wave antenna units 920 are always in a position that is not blocked by the user, thereby improving the stability of the non-millimeter wave antenna units 920 in transmitting and receiving wireless signals, and better ensuring the user's wireless experience.

[0083] In any of the above embodiments, optionally, the multi-function unit 120 is located in the display area of ​​the display panel 10, and the transmittance of the multi-function unit 120 and the shielding layer 200 is greater than or equal to 50%, so as to reduce the impact of the multi-function unit 120 on the display effect of the display panel 10. In other embodiments, when the multi-function unit 120 is disposed in the non-display area of ​​the display panel 10, the transmittance of the multi-function unit 120 is not limited.

[0084] The display surface of the display panel 10, i.e., the light-emitting surface of the display panel 10, is located closer to the light-emitting surface of the display panel 10 than the shielding layer 200. When a wireless signal is incident on the light-emitting surface of the display panel 10, it first enters the functional layer 100 and is reflected by the multifunctional unit 120 of the functional layer 100. Some of the wireless signal enters the shielding layer 200 through the gaps between adjacent functional units and is blocked by the shielding layer 200.

Optionally, each reflection unit 110 and each multi-function unit 120 are connected to different control circuits 610. For example, each reflection unit 110 and each multi-function unit 120 are connected to a control circuit 610, in which case the number of control circuits 610 is the sum of the number of reflection units 110 and the number of multi-function units 120. The reflection units 110 and the control circuits 610 are provided in a one-to-one correspondence, and the multi-function units 120 and the control circuits 610 are provided in a one-to-one correspondence.

[0097] In some optional embodiments, the display panel 10 further includes a control line 300 for connecting the reflective unit 110 and the control circuit 610. That is, the control line 300 is also used to connect the reflective unit 110 and the control circuit 610. The control line 300 and the multi-function control feeder 820 are arranged on the same layer, so that the control line 300 and the multi-function control feeder 820 can be manufactured and formed in the same process step, which can simplify the manufacturing process of the display panel 10. In other embodiments, the control line 300 and the multi-function control feeder 820 can also be arranged on different layers to facilitate more flexible routing of the control line 300 and the multi-function control feeder 820.

[0111] Optionally, the orthographic projections of the first reflective units 111 on the substrate 11 and the orthographic projections of the second reflective units 112 on the substrate 11 are arranged so as to at least partially overlap. This reduces the overall distribution area of ​​the two or more reflective units 110, reduces the size of the reflective surface assembly, and can reflect wireless signals in multiple frequency bands.

Optionally, the connecting portion 400 is multiplexed as a portion of at least one of the multi-function control feed line 820, the control line 300, and the RF line 810.

[0115] In these optional embodiments, the connecting portion 400 is arranged in the overlapping area of ​​the first multi-functional unit 121 and the second multi-functional unit 122, so that the connecting portion 400 extends along the thickness direction of the display panel 10 to simultaneously connect the first multi-functional unit 121 and the second multi-functional unit 122, which can simplify the structure of the connecting portion 400.

[0116] Optionally, a connecting portion 400 is also provided in the overlapping region of the first reflecting unit 111 and the second reflecting unit 112, with one end of the connecting portion 400 connected to the first multi-function unit 121 and the second multi-function unit 122, and the other end of the connecting portion 400 connected to the control line 300. By extending the connecting portion 400 along the thickness direction of the display panel 10, the first reflecting unit 111 and the second reflecting unit 112 can be simultaneously connected, thereby simplifying the structure of the connecting portion 400.

[0117] Optionally, the orthographic projection shape of the first reflecting unit 111 on the substrate 11 and the orthographic projection shape of the second reflecting unit 112 on the substrate 11 may be the same or different.

[0120] In these optional embodiments, since the first multifunctional unit 121 is relatively small, two or more first multifunctional units 121 are provided corresponding to the same second multifunctional unit 122, which can increase the number of arranged first multifunctional units 121 and improve the wireless communication performance of the first functional layer 101. The orthographic projections of the two or more first multifunctional units 121 on the substrate 11 are located within the orthographic projection of the same second multifunctional unit 122 on the substrate 11, making the arrangement of the first multifunctional units 121 and the second multifunctional units 122 more regular and facilitating preparation and molding.

[0121] Alternatively, the first reflecting unit 111 and the second reflecting unit 112 may be provided in a one-to-one correspondence.

[0132] In some optional embodiments, as shown in Figures 1 and 21, the display panel 10 further includes a signal line layer 11a. The multi-function unit 120 and the multi-function control feeder 820 can be disposed on the same layer and both located on the signal line layer 11a to simplify the structure of the display panel 10. Alternatively, as described above, when the multi-function unit 120 and the multi-function control feeder 820 are on different layers, as shown in Figure 22, the multi-function unit 120 is disposed on the signal line layer 11a, and the multi-function control feeder 820 is disposed on another conductive layer.

Alternatively, the multi-function control feeder 820 may be arranged in a conductive layer between the functional layer 100 and the shielding layer 200. For example, the multi-function control feeder 820 may be arranged in the signal line layer 11a, which may be located between the functional layer 100 and the shielding layer 200. Optionally, the reflective unit 110 and the multi-function unit 120 may be on the same layer, and the control line 300 connecting the reflective unit 110 may be on the same layer as the multi-function control feeder 820.

[0134] The signal line layer 11a can be arranged in various ways. For example, as shown in Figures 1 to 16, the signal line layer 11a includes a grid of metal wiring, at least some of which is multiplexed into at least one of the multi-function unit 120, the multi-function control feed line 820, the reflector unit 110, the control line 300, and the RF line 810.

The common electrode layer 11d is located on the side of the array substrate 11c facing the display surface of the display panel 10. The common electrode layer 11d is reused as a shielding layer 200. This allows the shielding layer 200 to reuse the original layer structure of the display panel 10, thereby simplifying the structure of the display panel 10.

[0143] As shown in Figures 27 to 31, embodiments of the present application further provide a wireless communication device, comprising the display panel 10 according to any of the first aspects described above. Since the wireless communication device provided in embodiments of the present application comprises the display panel 10 according to any of the above embodiments, the wireless communication device provided in embodiments of the present application has the beneficial effects of the display panel 10 according to any of the above embodiments of the first aspect, and thus will not be further elaborated here.

[0144] The wireless communication devices in the embodiments of the present application include but are not limited to mobile phones, wireless wearable devices, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, consoles, electronic billboards, transparent substrate billboards, and other devices with display functions.

[0145] In some optional embodiments, the wireless communication device further includes the aforementioned control component 600 , and controls the multi-function unit 120 to transmit antenna signals or reflect wireless signals through the radio frequency circuit 620 and the control circuit 610 of the control component 600 .

[0146] In some optional embodiments, as shown in Figures 28 to 31, the wireless communication device further includes a circuit board 500, which may be a flexible circuit board. At least one of the control circuit 610, the millimeter-wave RF circuit 621, and the non-millimeter-wave RF circuit 622 is disposed on the circuit board 500. The circuit board 500 can provide support for at least one of the control circuit 610, the millimeter-wave RF circuit 621, and the non-millimeter-wave RF circuit 622.

[0147] Optionally, the circuit board 500 has a bending region 502 and a mounting region 501. The bending region 502 is bent so that the mounting region 501 is located on the non-display side of the display panel 10. At least one of the control circuit 610, the millimeter-wave RF circuit 621, and the non-millimeter-wave RF circuit 622 is disposed in the mounting region 501. This can reduce the number of components on the display side and increase the display area ratio of the wireless communication device.

[0148] There are various ways to configure the number of circuit boards 500. The number of circuit boards 500 can be one, with the control circuit 610, millimeter-wave RF circuit 621, and non-millimeter-wave RF circuit 622 being disposed on the same circuit board 500. Alternatively, the number of circuit boards 500 can be two or more, with at least two of the control circuit 610, millimeter-wave RF circuit 621, and non-millimeter-wave RF circuit 622 disposed on different circuit boards 500. For example, the control circuit 610 is disposed on one circuit board 500, while the millimeter-wave RF circuit 621 and non-millimeter-wave RF circuit 622 are disposed on another circuit board 500. The control circuit 610 is used to control the multi-function unit 120 to reflect wireless signals. Configuring the control circuit 610 and the RF circuit 620 on different circuit boards 500 can alleviate signal crosstalk. The millimeter-wave RF circuit 621 and non-millimeter-wave RF circuit 622 are both used to control the multi-function unit 120 to transmit antenna signals. Configuring the millimeter-wave RF circuit 621 and non-millimeter-wave RF circuit 622 on the same circuit board 500 can simplify the structure of the wireless communication device.

[0149] Optionally, when the display panel 10 includes a multi-function control feeder 820, the RF circuit 620 and the control circuit 610 are both disposed on the circuit board 500. Optionally, a first signal line and a second signal line are disposed on the circuit board 500. The first signal line connects the multi-function control feeder 820 and the RF circuit 620, and the second signal line connects the multi-function control feeder 820 and the control circuit 610. Optionally, when the RF circuit 620 includes a millimeter-wave RF circuit 621 and a non-millimeter-wave RF circuit 622, the second signal line includes a first sub-line and a second sub-line. The first sub-line connects the multi-function control feeder 820 and the millimeter-wave RF circuit 621, and the second sub-line connects the non-millimeter-wave RF circuit 622 and the multi-function control feeder 820. Optionally, the multi-function control feeder 820 is disposed on the substrate 11. For example, the multi-function control feeder 820 can be disposed within the substrate 11 of the display panel 10, and the RF circuit 620 and the control circuit 610 are disposed on the circuit board 500. The multi-function control feeder 820 in the display panel 10 is connected to the RF circuit 620 and the control circuit 610 respectively through the first signal line and the second signal line on the flexible circuit board 500 .

[0150] In some optional embodiments, as shown in Figures 8, 10, 13, and 20, the wireless communication device further includes a baseband 700, which is configured to control the electrical connection or disconnection between the multi-function unit 120 and the control circuit 610. When the multi-function unit 120 functions as a reflector assembly and reflects wireless signals, the baseband 700 controls the electrical connection between the multi-function unit 120 and the control circuit 610. When the multi-function unit 120 functions as an antenna assembly 900, the baseband 700 controls the electrical disconnection between the multi-function unit 120 and the control circuit 610. The connection and disconnection herein refer to electrical connection and disconnection. When the multi-function unit 120 and the control circuit 610 are electrically connected, the control circuit 610 can change the electrical load of the multi-function unit 120. When the multi-function unit 120 and the control circuit 610 are electrically disconnected, the control circuit 610 cannot change the electrical load of the multi-function unit 120.

[0151] The baseband 700 can control the electrical connection or disconnection between the multi-function unit 120 and the control circuit 610 in various ways. For example, the baseband 700 can control the electrical connection or disconnection between the multi-function unit 120 and the control circuit 610 according to a preset time sequence and duration. For example, the baseband 700 controls the electrical connection between the multi-function unit 120 and the control circuit 610 for a time period t1, then controls the electrical disconnection between the multi-function unit 120 and the control circuit 610 for a time period t2, and then controls the electrical connection between the multi-function unit 120 and the control circuit 610 for a time period t1, and so on. The time period t1 and the time period t2 can be the same or different.

[0152] Optionally, when the wireless communication device includes a circuit board 500 connected to the display panel 10, the baseband 700 may be provided on the circuit board 500. The control circuit 610, the radio frequency circuit 620, and the baseband 700 may be provided on the same circuit board 500, or at least two of the control circuit 610, the radio frequency circuit 620, and the baseband 700 may be provided on the same circuit board 500, or the control circuit 610, the radio frequency circuit 620, and the baseband 700 may be provided on different flexible circuit boards 500.

[0153] In other optional embodiments, the display panel 10 further includes a reflection unit 110, and the baseband 700 is further used to obtain a first RF operating current of the multi-function unit 120 and a second RF operating current of at least one reflection unit 110. The baseband 700 is further used to control the multi-function unit 120 and the control circuit 610 to be electrically disconnected when the absolute value of the current difference between the first RF operating current and the second RF operating current is greater than or equal to a first preset threshold.

[0154] When the multi-function unit 120 is multiplexed into the antenna assembly 900, the operating current within the multi-function unit 120 is different from the operating current within the reflector unit 110, which is solely used to reflect wireless signals. In these optional embodiments, the baseband 700 is capable of obtaining the first RF operating current and the second RF operating current. When the absolute value of the difference between the first RF operating current and the second RF operating current is greater than a first preset threshold, the operating current difference between the multi-function unit 120 and the reflector unit 110 is too large. The multi-function unit 120 is multiplexed into the antenna assembly 900, and the baseband 700 controls the multi-function unit 120 to be electrically disconnected from the control circuit 610, so that the multi-function unit 120 can be in the operating mode of the antenna assembly 900.

[0155] The first preset threshold can be set according to the actual usage requirements of the user, and can be determined based on the dynamic range of the RF device connected to the antenna component 900 to be reused by the multi-function unit 120, the dynamic range of the RF device connected to the reflection unit 110, and the sensitivity of the baseband platform. As long as the absolute value of the RF current difference is greater than or equal to the first preset threshold, it can be determined that the multi-function unit 120 is currently reused as the antenna component 900 rather than the reflection surface component.

[0156] Optionally, the baseband 700 is further configured to control the multi-function unit 120 to be electrically connected to the control circuit 610 when the absolute value of the current difference between the first RF operating current and the second RF operating current is less than a first preset threshold. That is, when the absolute value of the RF current difference is less than the first preset threshold, it indicates that the operating current of the multi-function unit 120 and the RF operating current of the reflector unit 110 are substantially similar, and the multi-function unit 120 is multiplexed as a reflective surface component and reflects wireless signals together with the reflector unit 110. Therefore, the multi-function unit 120 and the control circuit 610 are electrically connected, and the control circuit 610 can control the operating state of the multi-function unit 120 when it is multiplexed as a reflective surface.

[0157] Optionally, the baseband 700 is further configured to obtain the second RF operating current as the RF operating current of the reflector unit 110 adjacent to the multi-function unit 120. That is, the baseband 700 is configured to obtain the first RF operating current of the multi-function unit 120 and the second RF operating current of the reflector unit 110 adjacent to the multi-function unit 120. Determining whether the multi-function unit 120 is multiplexed as a reflector surface based on the operating current of the reflector unit 110 adjacent to the multi-function unit 120 can improve determination accuracy, thereby improving control accuracy of the baseband 700.

[0158] In some optional embodiments, the wireless communication device further includes a low-noise amplifier 720 connected between the multi-function unit 120 and / or the reflector unit 110 and the baseband 700 to reduce the impact of noise signals on control accuracy. The baseband 700 can control the electrical connection or disconnection between the multi-function unit 120 and the control circuit 610 by controlling the low-noise amplifier 720. The low-noise amplifier 720 can be connected between the multi-function unit 120 and the baseband 700, or between the reflector unit 110 and the baseband 700, or both between the multi-function unit 120 and the baseband 700 and the reflector unit 110 and the baseband 700. Optionally, a filter 710 is further included, connected between the multi-function unit 120 and / or the reflector unit 110 and the baseband 700.

[0159] The control circuit 610 can be configured in a variety of ways. In some optional embodiments, the control circuit 610 includes a variable resistor 611, which is connected between the multi-function unit 120 and / or the reflector unit 110 and the baseband 700. When the control circuit 610 is used to control the multi-function unit 120, the variable resistor 611 is connected between the multi-function unit 120 and the baseband 700. By adjusting the resistance value of the variable resistor 611, the amplitude of the multi-function unit 120 when it is on the reflective surface can be adjusted. When the control circuit 610 is used to control the reflector unit 110, the variable resistor 611 is connected between the reflector unit 110 and the baseband 700. By changing the resistance value of the variable resistor 611, the amplitude of the reflector unit 110 can be adjusted.

[0160] Optionally, when the wireless communication device includes a low noise amplifier 720 , the variable resistor 611 may be connected between the low noise amplifier 720 and the baseband 700 .

[0161] Optionally, when the wireless communication device includes a circuit board 500 and a display panel 10 , the variable resistor 611 may be provided on the display panel 10 or the circuit board 500 .

[0162] Optionally, the control circuit 610 further includes a variable capacitor 613 and / or a variable inductor 612, and the variable capacitor 613 and / or the variable inductor 612 are connected between the multi-function unit 120 and the variable resistor 611. Alternatively, the variable capacitor 613 and / or the variable inductor 612 are connected between the reflector unit 110 and the variable resistor 611. When the control circuit 610 is used to control the multi-function unit 120, the variable capacitor 613 and / or the variable inductor 612 are connected between the multi-function unit 120 and the variable resistor 611. When the control circuit 610 is used to control the reflector unit 110, the variable capacitor 613 and / or the variable inductor 612 are connected between the reflector unit 110 and the variable resistor 611. By providing the variable capacitor 613 and / or the variable inductor 612 within the control circuit 610, characteristics such as the phase of the multi-function unit 120 and / or the reflector unit 110 can be controlled.

[0163] Optionally, the control circuit 610 also includes a second switch 614, which is used to control which circuit the multi-function unit 120 and / or the reflection unit 110 and the variable resistor 611 are electrically connected to each other. For example, the second switch 614 is used to control whether the multi-function unit 120 and / or the reflection unit 110 are directly electrically connected to the variable resistor 611, or whether the multi-function unit 120 and / or the reflection unit 110 are electrically connected to the variable resistor 611 via the variable capacitor 613, or whether the multi-function unit 120 and / or the reflection unit 110 are electrically connected to the variable resistor 611 via the variable inductor 612.

[0164] For example, the second switch 614 is a single-pole multi-throw switch, one end of the second switch 614 is connected to the multi-function unit 120 and / or the reflection unit 110, and the other end of the second switch 614 is provided with three lines, one line is directly electrically connected to the variable resistor 611, another line is electrically connected to the variable resistor 611 via the variable capacitor 613, and the last line is electrically connected to the variable resistor 611 via the variable inductor 612. By controlling the electrical connection relationship within the second switch 614, it can be determined via which line the multi-function unit 120 and / or the reflection unit 110 and the variable resistor 611 are connected to each other.

[0165] Optionally, the control circuit 610 further includes a downconverter 615 , which is connected between the variable resistor 611 and the baseband 700 .

[0166] The third aspect of the present application further provides a multifunctional component, comprising a functional layer 100, a shielding layer 200, and an antenna assembly 900.

[0167] In the embodiment of the present application, the functional layer 100 includes a multi-function unit 120, which can reflect wireless signals, thereby improving the wireless performance of the multi-function component. The shielding layer 200 is disposed on one side of the functional layer 100 to block wireless signals incident from the back of the functional layer 100. The antenna assembly 900 includes a millimeter wave antenna unit 910 and a non-millimeter wave antenna unit 920, enabling the multi-function component to transmit both millimeter wave antenna signals and non-millimeter wave antenna signals, further enriching the wireless communication capabilities of the multi-function component.
