[0055] In the description of this application, unless otherwise specified, "plurality" means more than two. Terms such as "upper," "lower," "left," "right," "inner," and "outer" to indicate positions or relationships are intended solely for the purpose of facilitating and simplifying the description of this application. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0056] The directional words that appear in the following description refer to the directions shown in the figures and do not limit the specific structure of the embodiments of this application. In the description of this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0057] With the development of display and wireless communication technologies, the requirements for the communication performance of wireless communication equipment are becoming increasingly higher. Intelligent Reflecting Surfaces (IRS) are an important communication design that is currently receiving widespread attention and research investment. This is because they 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 the surface (that is, by changing the electrical load of the reflective units). For example, the 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, antennas are also important functional components for wireless communication equipment for transmitting and receiving wireless signals.

[0058] 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. Beneath 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 electrically connected to the reflective elements and is used to regulate 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.

[0059] A metasurface is a planar design with periodic conductive patterns, which helps to enhance electromagnetic performance. Therefore, metasurfaces can be used to improve antenna performance.

[0060] In order to better understand the present application, the display panel assembly, multi-function assembly, transceiver assembly and wireless communication device of the embodiment of the present application are described in detail below with reference to Figures 1 to 42.

[0061] Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a schematic structural diagram of a display panel assembly 10 provided in an embodiment of the present application, and FIG. 2 is a cross-sectional view taken at AA in FIG. 1 .

[0062] As shown in Figures 1 and 2, an embodiment of the first aspect of the present application provides a display panel assembly 10, which includes a substrate 11, an antenna assembly 900, and a metasurface assembly. The antenna assembly 900 is disposed on the substrate 11 and includes an antenna unit 901, which is used to transmit and receive wireless signals. The metasurface assembly is disposed on the substrate 11 and includes a plurality of metasurface units 130, which are used to improve the performance of wireless signals transmitted and received by the antenna unit 901. Both the antenna assembly 900 and the metasurface assembly include a transparent structural layer.

[0063] In the display panel assembly 10 provided in the embodiment of the present application, the display panel assembly 10 includes a substrate 11, an antenna assembly 900, and a metasurface assembly. The antenna unit 901 in the antenna assembly 900 is capable of transmitting and receiving wireless signals. The metasurface unit 130 of the metasurface assembly can improve the performance of wireless signals transmitted and received by the antenna unit 901, improve the transceiver performance of the antenna unit 901, and thus enhance the wireless communication performance of the display panel assembly 10. In addition, both the antenna assembly 900 and the metasurface assembly include a transparent structural layer, which can improve the impact of the antenna assembly 900 and the metasurface assembly on the display effect of the display panel assembly 10.

[0064] Optionally, both the antenna unit 901 and the metasurface unit 130 are used to transmit and receive wireless signals. The difference between the metasurface unit 130 and the antenna unit 901 is that the antenna unit 901 is connected to a feed and is connected to the RF circuit through the feed; while there is no direct electrical connection between the metasurface unit 130 and the RF circuit or the antenna unit 901. Optionally, the metasurface unit 130 is suspended within the display panel assembly 10. The suspension of the metasurface unit 130 means that while the metasurface unit 130 is used to improve the performance of the antenna unit 901 in transmitting and receiving wireless signals, it is not directly electrically connected to other components.

[0065] There are many ways to set up the transparent structural layer. For example, as shown in Figure 1, the transparent structural layer includes a grid-shaped metal wiring. For example, the transparent structural layer is a grid structural layer of a light-transmitting portion 170 formed by a plurality of grid bars 160 and a plurality of grid bars 160. For example, the antenna component 900 and / or the super-surface component is arranged in the grid structural layer, and at least a portion of the grid bars 160 of the grid structural layer forms the antenna unit 901 and / or the super-surface unit 130. In the same grid structural layer, the grid bars 160 used as the antenna unit 901 and / or the super-surface unit 130 are insulated from the grid bars 160 at other positions to avoid short-circuiting of the antenna unit 901 and / or the super-surface unit 130 with other grid bars 160. In Figure 1, light gray lines illustrate a way of setting up the grid structure, and black lines illustrate the setting positions of the antenna unit 901 and the super-surface unit 130.

[0066] Optionally, the display panel assembly 10 further includes a pixel definition layer, which includes a pixel defining portion and a pixel opening enclosed by the pixel defining portion. The transparent structural layer is located on the side of the pixel definition layer facing away from the substrate, and the orthographic projection of at least some of the grid bars 160 on the substrate 11 is located within the orthographic projection of the pixel defining portion on the substrate 11. The pixel opening is used to dispose a light-emitting unit to achieve a light-emitting display of the display panel assembly 10.

[0067] In these optional embodiments, at least part of the grid bars 160 are projected onto the substrate 11 within the projection of the pixel defining portion onto the substrate 11 , so that this part of the grid bars 160 does not affect the light emission of the light-emitting unit, thereby improving the display effect of the display panel assembly 10 .

[0068] Optionally, the orthographic projections of the grid bars 160 on the substrate 11 are all located within the orthographic projections of the pixel defining portions on the substrate 11 .

[0069] In other optional embodiments, as shown in FIG3 , the transparent structural layer includes a light-transmitting conductive layer, and the light-transmitting conductive layer includes a light-transmitting conductive material. The light-transmitting conductive material includes, for example, indium tin oxide (ITO), indium zinc oxide, and the like, so that the transparent structural layer is both conductive and light-transmitting. In these optional embodiments, the antenna assembly 900 and / or the metasurface assembly includes a transparent structural layer, that is, at least part of the antenna unit 901 and / or the metasurface unit 130 is made of a light-transmitting conductive material, so that at least part of the antenna unit 901 and / or the metasurface unit 130 has both light-transmitting and conductive properties, thereby improving its effect on the display effect of the display panel assembly 10.

[0070] Optionally, the light transmittance of the transparent structural layer is greater than or equal to 50%, for example, the light transmittance of the transparent structural layer is greater than or equal to 60%, 62%, 65%, 70%, 78%, 80%, 86%, or even 90%, so as to better improve the influence of the antenna unit 901 and / or the metasurface unit 130 on the display effect of the display panel assembly 10.

[0071] Optionally, the transparent structural layer included in the antenna assembly 900 and the transparent structural layer included in the metasurface assembly may be arranged in the same or different manners. For example, the transparent structural layers included in the antenna assembly 900 and the metasurface assembly are both grid structural layers, or the antenna assembly 900 and the metasurface assembly include light-transmitting conductive materials. Alternatively, the transparent structural layer included in the antenna assembly 900 is a grid structural layer, and the transparent structural layer included in the metasurface assembly includes a light-transmitting conductive material. Alternatively, the transparent structural layer included in the antenna assembly 900 includes a light-transmitting conductive material, and the transparent structural layer included in the metasurface assembly is a grid structural layer.

[0072] Optionally, the display panel assembly 10 further includes a conductive functional structure, and the antenna unit 901 and / or the super-surface unit 130 are arranged in the same layer as the conductive functional structure. Optionally, the conductive functional structure may be a touch electrode structure of the display panel, and the antenna unit 901 and / or the super-surface unit 130 and the touch electrode structure are arranged in the touch layer. Alternatively, the conductive functional structure may be a pixel electrode and / or a common electrode of the display panel, and the antenna unit 901 and / or the super-surface unit 130 and the pixel electrode are arranged in the pixel electrode layer. Alternatively, the common electrode layer includes a plurality of mutually insulated common electrodes, and the antenna unit 901 and / or the super-surface unit 130 and the common electrode are arranged in the common electrode layer.

[0073] In some optional embodiments, as shown in Figures 4 to 6, the display panel assembly 10 further includes a smart reflective surface, which includes a reflective component and a conductive layer 200. The conductive layer 200 is disposed on the side of the reflective component facing the substrate 11. The reflective component includes a plurality of reflective units 110, each of which is configured to reflect wireless signals. At least one reflective unit 110 is multiplexed into at least one metasurface unit 130, and / or at least one reflective unit 110 is multiplexed into at least one antenna unit 901. The conductive layer 200 acts as the metal plate of the aforementioned IRS to shield and reflect wireless signals.

[0074] In the display panel assembly 10 provided in the embodiment of the present application, the reflective unit 110 of the reflective assembly is capable of reflecting wireless signals, enabling the display panel assembly 10 to not only transmit and receive wireless signals via the antenna unit 901 but also reflect wireless signals via the reflective unit 110, thereby enriching the wireless communication functionality of the display panel assembly 10. The reflective unit 110 is multiplexed as one of the metasurface unit 130 and the antenna unit 901, simplifying the structure of the display panel assembly 10. The conductive layer 200 can shield signals incident from two adjacent reflective units 110 to support the normal operation of the smart reflective surface.

[0075] When the reflective unit 110 is multiplexed into the metasurface unit 130, the reflective unit 110 has both a reflective function and a metasurface function, that is, the reflective unit 110 can be used as a smart reflective surface to reflect wireless signals transmitted from the outside toward the display panel assembly 10, and the reflective unit 110 can also enhance the antenna signals transmitted and received by the antenna unit 901. When the reflective unit 110 is multiplexed into the antenna unit 901, the reflective unit 110 has both a reflective function and a function of transmitting and receiving wireless signals, that is, the reflective unit 110 can be used as a smart reflective surface to reflect wireless signals transmitted from the outside toward the display panel assembly 10, and the reflective unit 110 can also transmit and receive wireless signals.

[0076] In some optional embodiments, referring to Figures 4 to 6 , at least one reflective unit 110 and at least one metasurface unit 130 are multiplexed into a first multi-functional unit 120a. That is, at least one reflective unit 110 and at least one metasurface unit 130 integrally form a first multi-functional unit 120a, and the orthographic projection of at least one first multi-functional unit 120a on the substrate 11 at least partially overlaps with the orthographic projection of the antenna unit 901 on the substrate 11. The dotted line in Figure 1 illustrates the layout of the antenna unit 901.

[0077] In these optional embodiments, the first multi-functional unit 120a has reflection and metasurface effects, and at least one first multi-functional unit 120a overlaps with the antenna unit 901, so that the first multi-functional unit 120a can better improve the transceiver performance of the antenna unit 901.

[0078] Optionally, the display panel assembly 10 includes a control line 300 and a radio frequency line 810, the radio frequency line 810 is used to connect the antenna unit 901 and the radio frequency circuit 620, and the control line 300 is used to connect the reflection unit 110 and the control circuit 610. The position of the radio frequency line 810 is indicated by a dotted line in Figure 4. Optionally, the control circuit 610 can be set in the display panel assembly 10. Alternatively, when the display panel assembly 10 is used in a wireless communication device, the control circuit 610 is set in the wireless communication device. Optionally, the radio frequency circuit 620 can be set in the display panel assembly 10. Alternatively, when the display panel assembly 10 is used in a wireless communication device, the radio frequency circuit 620 is set in the wireless communication device. Optionally, the first multi-function unit 120a is connected to the control circuit 610 via the control line 300 to be multiplexed as the reflection unit 110, and the first multi-function unit 120a is electrically disconnected from the control circuit 610 when it is multiplexed as the metasurface unit 130. That is, the first multi-function unit 120a in the metasurface working mode has no direct electrical connection with the control circuit 610 and the RF circuit 620, the metasurface unit 130 has no direct electrical connection with the RF circuit 620, and the antenna unit 901 is electrically connected to the RF circuit 620 through the RF line 810.

[0079] Continuing with FIG1 , the RF line 810 is formed by a grid structure, and the RF line 810 includes multiple metal wires extending in different directions. Alternatively, as shown in FIG4 , the RF line 810 is formed by two parallel metal wires. In other embodiments, the RF line 810 may also include only one wire, or the RF line may include multiple metal wires, etc., as long as the RF line 810 can connect the antenna unit 901 and the RF circuit 620. Similarly, there may be multiple ways to set up other wires (such as the control line 300).

[0080] When the reflective unit 110 and the metasurface unit 130 are multiplexed into the first multifunctional unit 120a, the reflective component and the metasurface component are disposed on the same layer. The first multifunctional unit 120a can be disposed in various locations. The first multifunctional unit 120a can be disposed on the side of the antenna assembly 900 facing toward or away from the substrate 11.

[0081] In some optional embodiments, as shown in Figures 5 and 6, the first multifunctional unit 120a is located on the side of the antenna unit 901 facing the display surface of the display panel assembly 10. That is, the first multifunctional unit 120a is located on the side of the antenna unit 901 facing away from the substrate 11. When the first multifunctional unit 120a is in the working state of the reflection unit 110 and is used to reflect the wireless signal line, it can prevent the first multifunctional unit 120a from being blocked by the antenna unit 901 and affecting the operation of the first multifunctional unit 120a.

[0082] Optionally, the first multi-function unit 120a and the antenna unit 901 can be arranged in a one-to-one correspondence, that is, the orthographic projection of each first multi-function unit 120a on the substrate 11 and the orthographic projection of each antenna unit 901 on the substrate 11 are at least partially overlapped, so that each antenna unit 901 can be amplified by the first multi-function unit 120a.

[0083] In other embodiments, the first multi-function unit 120a and the antenna unit 901 may be arranged in a one-to-many or many-to-one configuration, i.e., the same first multi-function unit 120a is configured to correspond to multiple antenna units 901, and the orthographic projections of the same first multi-function unit 120a on the substrate 11 and the orthographic projections of the multiple antenna units 901 on the substrate 11 at least partially overlap. Alternatively, multiple first multi-function units 120a are configured to correspond to the same antenna unit 901, and the orthographic projections of the multiple first multi-function units 120a on the substrate 11 are located within the orthographic projection of the same antenna unit 901 on the substrate 11.

[0084] In some other embodiments, among the multiple first multi-functional units 120a, the orthographic projections of some first multi-functional units 120a on the substrate 11 and the orthographic projections of the antenna unit 901 on the substrate 11 at least partially overlap, and the orthographic projections of other first multi-functional units 120a on the substrate 11 and the orthographic projections of the antenna unit 901 on the substrate 11 are staggered with each other. As long as there is at least one first multi-functional unit 120a whose orthographic projection on the substrate 11 and the orthographic projection of the antenna unit 901 on the substrate 11 at least partially overlap, it will be sufficient.

[0085] Optionally, the orthographic projection shapes and sizes of the plurality of first multi-function units 120 a on the substrate 11 may be the same or different.

[0086] In some optional embodiments, as shown in FIG7 , the metasurface assembly further includes an auxiliary metasurface unit 131, which is located on at least one side of the first multi-function unit 120a. The auxiliary metasurface unit 131 and the first multi-function unit 120a are configured to jointly enhance the wireless signals received and transmitted by the antenna unit 901, thereby further enhancing the performance improvement of the metasurface assembly on the antenna assembly 900.

[0087] Optionally, at least one auxiliary metasurface unit 131 is provided on the circumferential side of at least one first multi-function unit 120a. Optionally, at least one auxiliary metasurface unit 131 is provided on the circumferential side of each first multi-function unit 120a. Optionally, two or more auxiliary metasurface units 131 distributed at intervals are provided on the circumferential side of each first multi-function unit 120a. Optionally, the arrangement of the two or more auxiliary metasurface units 131 provided on the circumferential side of each first multi-function unit 120a is the same, so that the performance improvement effect of the metasurface component on each antenna unit 901 is similar.

[0088] Optionally, the orthographic projection of each auxiliary metasurface unit 131 on the substrate 11 at least partially overlaps with the orthographic projection of each antenna unit 901 on the substrate 11 , so as to enhance the performance improvement effect of the auxiliary metasurface unit 131 on the antenna unit 901 .

[0089] Optionally, the shapes and sizes of the multiple auxiliary metasurface units 131 located on the periphery of the same first multi-function unit 120a may be the same or different.

[0090] Optionally, the auxiliary metasurface unit 131 and the first multifunctional unit 120 a are arranged in the same layer, so that the auxiliary metasurface unit 131 and the first multifunctional unit 120 a can be prepared and formed in the same process step to simplify the preparation process of the display panel assembly 10 .

[0091] In other optional embodiments, as shown in Figures 8 and 9, at least one reflective unit 110 and at least one antenna unit 901 are multiplexed into a second multi-functional unit 120b. That is, the second multi-functional unit 120b has a reflective function and a function of transmitting and receiving wireless signals. The second multi-functional unit 120b can be used as a reflective surface to reflect wireless signals transmitted from the outside toward the display panel assembly 10, and the second multi-functional unit 120b can also be used as an antenna to transmit and receive wireless signals. Therefore, the second multi-functional unit 120b can be connected to the control circuit 610 via the control line 300, and can also be connected to the radio frequency circuit 620 via the radio frequency line 810. The location of the metasurface unit 130 is indicated by a dotted line in Figure 5.

[0092] Optionally, in FIG. 8 , the control line 300 may be formed of a plurality of metal wires extending in different directions, or the control line 300 may include a single metal wire, as long as the control line 300 can achieve electrical connection between the second multi-function unit 120 b and the control circuit 610 .

[0093] When the reflection unit 110 and the antenna unit 901 are multiplexed into the second multi-function unit 120b, the second multi-function unit 120b and the metasurface component can be arranged in the same layer or in different layers.

[0094] For example, as shown in Figures 10 and 11, the second multi-function unit 120b and the metasurface assembly are arranged in the same layer, and the metasurface unit 130 is located on at least one side of the second multi-function unit 120b in the circumferential direction. Optionally, at least one second multi-function unit 120b is provided with at least one metasurface unit 130 in the circumferential direction.

This allows the metasurface unit 130 to improve the performance of the antenna wireless signal received and transmitted by the second multi-function unit 120b.

[0096] When the second multi-functional unit 120b and the metasurface component are arranged in different layers, as shown in FIG8 , the second multi-functional unit 120b and the metasurface unit 130 are arranged in a one-to-one correspondence, that is, the orthographic projection of each second multi-functional unit 120b on the substrate 11 and the orthographic projection of each metasurface unit 130 on the substrate 11 at least partially overlap. Alternatively, as shown in FIG12 and FIG13 , a plurality of metasurface units 130 are arranged in correspondence with the same second multi-functional unit 120b. When a plurality of metasurface units 130 and the same second multi-functional unit 120b are arranged in correspondence, the orthographic projection of at least one of the plurality of metasurface units 130 on the substrate 11 at least partially overlaps with the orthographic projection of its corresponding second multi-functional unit 120b on the substrate 11, so as to enhance the performance improvement effect of the metasurface unit 130 on the second multi-functional unit 120b.

[0097] When the second multi-functional unit 120b and the metasurface assembly are arranged in different layers, at least part of the metasurface units 130 are located on the side of the second multi-functional unit 120b facing the display surface of the display panel assembly 10, and / or, at least part of the metasurface units 130 are located on the side of the second multi-functional unit 120b away from the display surface of the display panel assembly 10. That is, at least part of the metasurface units 130 are located on the side of the second multi-functional unit 120b facing away from the substrate 11, and / or, at least part of the metasurface units 130 are located on the side of the second multi-functional unit 120b facing the substrate 11.

[0098] For example, multiple super-surface units 130 are arranged in the same layer, and these super-surface units 130 can be located on the side of the second multi-functional unit 120b facing the display surface of the display panel assembly 10, or, as shown in Figure 14, these super-surface units 130 can be located on the side of the second multi-functional unit 120b facing away from the display surface of the display panel assembly 10.

[0099] Alternatively, multiple super-surface units 130 are arranged in different layers, and a part of the multiple super-surface units 130 are located on the side of the second multi-functional unit 120b facing the display surface of the display panel assembly 10, and the other part is located on the side of the second multi-functional unit 120b facing away from the display surface of the display panel assembly 10.

[0102] Optionally, when the reflection unit 110 and the antenna assembly 900 are multiplexed into a second multi-function unit 120b, as shown in Figures 15 and 16, the RF line 810 and the control line 300 can be multiplexed into a multi-function control feeder 820, so that the second multi-function unit 120b can be simultaneously connected to the RF circuit 620 and the control circuit 610 through the multi-function control feeder 820.

[0103] As shown in Figures 17 and 18, the number of multi-function control feeders 820 connected to the same second multi-function unit 120b is more than two, and the same second multi-function unit 120b can be connected to more than two control circuits 610 and / or RF circuits 620 through more than two multi-function control feeders 820.

The RF circuit 620 includes a millimeter wave RF circuit 621 and a non-millimeter wave RF circuit 622.

[0105] Optionally, the second multi-function unit 120b is multiplexed into the millimeter wave antenna unit 910, and the second multi-function unit 120b can also be used to transmit and receive millimeter wave antenna signals.

[0106] Optionally, the second multi-function unit 120b may be multiplexed as a part of the non-millimeter wave antenna unit 920 by: one second multi-function unit 120b being multiplexed as a part of the non-millimeter wave antenna unit 920; or at least two adjacent second multi-function units 120b being connected via a connection signal line 150 and multiplexed as a part of the non-millimeter wave antenna unit 920; or at least two adjacent second multi-function units 120b being connected via a connection signal line 150 and multiplexed as a part of the non-millimeter wave antenna unit 920. The second multi-function unit 120b being multiplexed as a part of the non-millimeter wave antenna unit 920 means that the second multi-function unit 120b can have the functions of the non-millimeter wave antenna unit 920 and be used to transmit and receive non-millimeter wave wireless signals.

[0107] Optionally, when at least two adjacent second multi-function units 120b are connected through the connecting signal line 150 and multiplexed as part of the non-millimeter wave antenna unit 920, the at least two adjacent second multi-function units 120b are connected in series and / or in parallel with each other through the connecting signal line 150 and multiplexed as part of the non-millimeter wave antenna unit 920.

[0108] Optionally, the second multi-function unit 120b multiplexed as the millimeter wave antenna unit 910 and the second multi-function unit 120b multiplexed as a part of the non-millimeter wave antenna unit 920 can be the same second multi-function unit 120b, or the second multi-function unit 120b multiplexed as the millimeter wave antenna unit 910 and the second multi-function unit 120b multiplexed as a part of the non-millimeter wave antenna unit 920 can be different second multi-function units 120b.

[0109] 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 second multi-function unit 120b can be multiplexed as the millimeter wave radiating portion.

[0110] For example, when the display panel assembly 10 is used in a wireless communication device that includes a control circuit 610 and a radio frequency circuit 620, the second multi-function unit 120b and the control circuit 610 are electrically connected to each other, so that the control circuit 610 can control the second multi-function unit 120b to reflect wireless signals. 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 second multi-function unit 120b so that the second multi-function unit 120b is multiplexed into a millimeter-wave antenna unit 910 and is used to transmit and receive millimeter-wave wireless signals. The non-millimeter-wave radio frequency circuit 622 is connected to at least one second multi-function unit 120b so that the second multi-function unit 120b is multiplexed into a portion of the non-millimeter-wave antenna unit 920 and is used to transmit and receive non-millimeter-wave wireless signals.

[0112] In other embodiments, at least one of the plurality of second multifunctional units 120b is multiplexed into the millimeter-wave antenna unit 910, and at least one of the remaining second multifunctional units 120b is multiplexed into a portion of the non-millimeter-wave antenna unit 920. That is, the second multifunctional unit 120b multiplexed into the millimeter-wave antenna unit 910 and the second multifunctional unit 120b multiplexed into a portion of the non-millimeter-wave antenna unit 920 are different second multifunctional units 120b, which can improve mutual crosstalk between signals.

[0113] Optionally, as shown in FIG21 , the number of non-millimeter wave antenna units 920 and / or millimeter wave antenna units 910 can be multiple to improve the ability of the display panel assembly 10 to transmit and receive non-millimeter wave signals and / or millimeter wave signals. Alternatively, as shown in FIG19 and FIG22 , the number of non-millimeter wave antenna units 920 can be one. FIG22 differs from FIG19 in that the number of second multi-function units 120b included in the non-millimeter wave antenna unit 920 is different.

[0114] Optionally, when the display panel assembly 10 includes the control line 300 and the second multi-function unit 120b, as shown in Figure 2, the control line 300 and the second multi-function unit 120b can be arranged in the same layer.

[0116] In some optional embodiments, as shown in Figures 19 and 20, as described above, the display panel assembly 10 also includes a multi-function control feeder 820, one end of the multi-function control feeder 820 is connected to the second multi-function unit 120b, 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 second multi-function unit 120b through the multi-function control feeder 820.

[0117] When the second multi-function unit 120b 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 second multi-function unit 120b is multiplexed as the 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 second multi-function unit 120b 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.

[0118] Optionally, as shown in Figures 19 to 24, the display panel assembly 10 further includes a radio frequency line 810, which connects the radio frequency circuit 620 to the second multi-function unit 120b. 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.

[0119] Optionally, the multi-function control feeder 820 is multiplexed into the millimeter-wave feeder 811 and the control line 300. The display panel assembly 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 second multi-function unit 120b. The multi-function control feeder 820 connects the second multi-function unit 120b with the millimeter-wave RF circuit 621 and the control circuit 610. Alternatively, the multi-function control feeder 820 is multiplexed into the millimeter-wave feeder 811 and the non-millimeter-wave feeder 812. The display panel assembly 10 includes a control line 300 and a multi-function control feeder 820. The control line 300 connects the control circuit 610 and the second multi-function unit 120b. The multi-function control feeder 820 connects the second multi-function unit 120b with the millimeter-wave RF circuit 621 and the non-millimeter-wave RF circuit 622. Alternatively, 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 second multi-function unit 120b with the millimeter wave RF circuit 621, the non-millimeter wave RF circuit 622 and the control circuit 610.

[0120] In some optional embodiments, as shown in Figures 16 to 26, more than two second multi-function units 120b are interconnected through a connecting signal line 150 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 second multi-function units 120b, which can further simplify the structure of the non-millimeter wave antenna unit 920.

[0121] Optionally, at least one of the two or more second multi-function units 120 b 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 assembly 10 .

[0122] In any of the above embodiments, there are various ways to set up the connecting signal line 150. For example, the connecting signal line 150 may include one conductor, or the connecting signal line 150 may include multiple conductors arranged side by side, or the connecting signal line 150 may include multiple conductors arranged side by side and a bridge line connecting the conductors arranged side by side.

[0123] When the second multifunctional units 120b, which are interconnected and 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 150 is no greater than the width of the millimeter-wave antenna units 910. Optionally, the millimeter-wave antenna units 910 include millimeter-wave conductive lines, and the line width of at least a portion of the connecting signal line 150 is no greater than the width of the millimeter-wave conductive lines within the millimeter-wave antenna units 910.

[0124] 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 part of the area connecting the signal line 150 is smaller than the width of the millimeter wave antenna unit 910, which means that the line width of at least a part of the area connecting the signal line 150 is smaller than the sum of the widths of the multiple millimeter wave conductors in the millimeter wave antenna unit 910.

[0125] In the embodiment of the present application, when the line width of at least a portion of the connecting signal line 150 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 150 is relatively narrow, and therefore the connecting signal line 150 has a relatively high impedance. Therefore, the connecting signal line 150 has a relatively good filtering and blocking effect on currents in the millimeter-wave band. However, the connecting signal line 150 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 150 relatively well, while millimeter-wave currents are blocked by the connecting signal line 150.

[0126] The millimeter wave current refers to the current corresponding to the millimeter wave band wireless signal transmitted and received 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 transmitted and received by the non-millimeter wave antenna unit 920.

[0127] Optionally, when the width of at least a portion of the connecting signal line 150 is no greater than the width of the millimeter-wave antenna unit 910, as shown in FIG19 , when the connecting signal line 150 includes a single conductor, the width of a single conductor within the connecting signal line 150 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 150. In other embodiments, when the connecting signal line 150 includes multiple conductors, the sum of the widths of the multiple conductors within the connecting signal line 150 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 150. As shown in FIG19 , when the first direction X and the second direction Y are perpendicular and the connecting signal line 150 extends along the second direction Y, the width of the connecting signal line 150 is in the first direction X, and the width of the millimeter-wave conductor is also in the first direction X.

[0128] In an embodiment of the present application, when the sum of the widths of the wires in the connecting signal line 150 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 150, that is, the width of the connecting signal line 150 is narrower, the connecting signal line 150 has a higher impedance, and therefore the connecting signal line 150 has a better filtering and blocking effect on the current in the millimeter-wave band.

[0129] The signal lines 150 can be configured in a variety of ways. They 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, they can be a combination of at least two of a straight, zigzag, and curved shape.

[0130] In some optional embodiments, as shown in Figures 20 and 26, 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.

[0131] Optionally, the non-millimeter wave antenna unit 920 can be connected to the first signal voltage 140 through a multiplexed second multi-function unit 120b, that is, at least one second multi-function unit 120b 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 150.

[0132] 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 .

[0133] 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.

[0134] Two or more millimeter-wave antenna units 910 are spaced apart around the perimeter of the display panel assembly 10, and the millimeter-wave antenna units 910 are located at different locations within the display panel assembly 10. When a user uses various gestures to operate the display panel assembly 10, the millimeter-wave antenna units 910 are more likely to be unobstructed by the user, thereby improving the stability of the millimeter-wave antenna units 910 in transmitting and receiving wireless signals, thereby better ensuring the user's wireless experience.

[0135] Optionally, the non-millimeter wave antenna units 920 are spaced around the periphery of the display panel assembly 10, and the non-millimeter wave antenna units 920 are distributed at different locations on the display panel assembly 10. When the user uses different gestures to operate the display panel assembly 10, the non-millimeter wave antenna units 920 are more likely to be 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, thereby better ensuring the user's wireless experience.

[0136] Optionally, each second multi-function unit 120b is connected to at least one control circuit 610, and different second multi-function units 120b are connected to different control circuits 610, so that each second multi-function unit 120b is individually controlled by the control circuit 610. Optionally, each second multi-function unit 120b is connected to at least one radio frequency circuit 620, for example, each second multi-function unit 120b is connected to at least one millimeter-wave radio frequency circuit 621 and at least one non-millimeter-wave radio frequency circuit 622, and different second multi-function units 120b are connected to different radio frequency circuits 620, so that each second multi-function unit 120b is individually controlled by the radio frequency circuit 620.

[0137] Optionally, the orthographic projections of the two or more second multi-function units 120 b on the substrate 11 are located within the orthographic projection of the conductive layer 200 on the substrate 11 .

[0138] Optionally, at least one reflective unit 110 is multiplexed into one of the metasurface unit 130 and the antenna unit 901 to form a multi-function unit 120. The display panel assembly 10 further includes a functional layer 100, and the multi-function unit 120 is disposed on the functional layer 100. That is, the first multi-function unit 120a and the second multi-function unit 120b can be collectively referred to as the multi-function unit 120, and the multi-function unit 120 is located on the functional layer 100.

[0139] In some optional embodiments, as shown in FIG. 27 , the number of the functional layers 100 is two or more, and at least two multifunctional units 120 located in different functional layers 100 have different orthographic projection areas on the substrate 11 .

[0140] In these optional embodiments, by providing two or more functional layers 100 and disposing multi-function units 120 of different sizes in different functional layers 100, the multi-function units 120 can reflect wireless signals of different frequency bands, or can transmit and receive antenna signals of different frequency bands, thereby further improving the wireless communication performance of the display panel assembly 10. The multi-function unit 120 can be a first multi-function unit 120a and / or a second multi-function unit 120b.

[0141] In some optional embodiments, a portion of the multiple reflective units 110 is multiplexed into the antenna unit 901, that is, a portion of the multiple reflective units 110 is multiplexed with the antenna unit 901 into the second multi-function unit 120b, and another portion of the multiple reflective units 110 can be multiplexed into a metasurface, or another portion of the multiple reflective units 110 exists only as reflective units 110. For example, the multiple reflective units 110 include a first reflective unit 111 and a second reflective unit 112, the first reflective unit 111 is multiplexed with the antenna unit 901 into the second multi-function unit 120b, and the second reflective unit 112 exists only as the reflective unit 110, and the second reflective unit 112 is not multiplexed into the antenna unit 901 or the metasurface unit 130.

[0142] Optionally, the first reflective unit 111 and the antenna unit 901 are multiplexed into a second multi-function unit 120b. The second reflective unit 112 and the second multi-function unit 120b are both connected to a control circuit 610. The control circuit 610 is configured to control the second reflective unit 112 and the second multi-function unit 120b to reflect wireless signals. Optionally, each second reflective unit 112 and each second multi-function unit 120b is connected to a different control circuit 610. Optionally, two or more second multi-function units 120b are arranged in an array within the same functional layer 100.

[0143] Optionally, the orthographic projection of the second reflecting unit 112 on the substrate 11 is located within the orthographic projection of the conductive layer 200 on the substrate 11 , so that the conductive layer 200 can also block wireless signals that are not reflected by the second reflecting unit 112 .

[0144] In some optional embodiments, the first reflective unit 111 and the antenna unit 901 are multiplexed into a second multi-function unit 120b. Multiple second reflective units 112 are combined to form a reflective group, and the second multi-function unit 120b is located on at least one side of the reflective group in a circumferential direction. That is, the second multi-function unit 120b, which is multiplexed into the antenna unit 901 and the reflective unit 110, is disposed on the circumference of the reflective group solely for reflecting wireless signals. The second multi-function unit 120b is disposed closer to the edge of the wireless communication device to reduce the impact of the second multi-function unit 120b on the display effect of the wireless communication device.

[0145] Optionally, at least some of the second multi-function units 120b and the second reflective unit 112 are disposed in the same layer, for example, all of the second multi-function units 120b and the second reflective unit 112 are disposed in the same layer, so that the second multi-function units 120b and the second reflective unit 112 can be manufactured and formed in the same process step, thereby simplifying the manufacturing process of the wireless communication device. Optionally, the orthographic projection size and shape of the second multi-function units 120b disposed in the same layer on the substrate 11 are the same as the orthographic projection size and shape of the second reflective unit 112 on the substrate 11, thereby simplifying the shape arrangement of the second multi-function units 120b and the second reflective unit 112 disposed in the same layer.

[0146] Optionally, the multi-function control feed line 820 and the second multi-function unit 120 b may be provided on the same layer to simplify the number of layer structures of the display panel assembly 10 .

[0147] Alternatively, optionally, the multi-function control feeder 820 and the second multi-function unit 120 b may be arranged in different layers, so that the arrangement of the second multi-function unit 120 b and the arrangement of the multi-function control feeder 820 do not affect each other.

[0198] Optionally, the transparent structural layer, the antenna unit 901 in the antenna assembly 900, and the super-surface unit 130 of the super-surface assembly are arranged as described in the display panel assembly 10 provided in the first aspect above. The arrangements of the antenna unit 901 and the super-surface unit 130 of the super-surface assembly in the display panel assembly 10 provided in the first aspect embodiment above can be applied to the wireless signal transceiver assembly provided in the third aspect embodiment, and will not be repeated here.

Since the wireless communication device provided in embodiments of the present application comprises the display panel assembly 10, or the multi-function assembly, or the wireless signal transceiver assembly of any of the above embodiments, the wireless communication device provided in embodiments of the present application has the beneficial effects of the display panel assembly 10, or the multi-function assembly, or the wireless signal transceiver assembly of any of the above embodiments of the first aspect, and no further details are given here.

[0201] In some optional embodiments, the wireless communication device further includes a control component 600, which includes a radio frequency circuit 620 and a control circuit 610, and the radio frequency circuit 620 and the control circuit 610 of the control component 600 control the multi-function unit 120 to transmit and receive antenna signals or reflect wireless signals.

[0202] In some optional embodiments, as shown in Figures 38 to 42, 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.

[0203] 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 assembly 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.

[0204] 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 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 change the electrical load of the second multi-function unit 120b. 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 second multi-function unit 120b in transmitting and receiving 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.

[0205] Optionally, when the display panel assembly 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 assembly 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 assembly 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 .

[0206] In some optional embodiments, as shown in Figures 11, 13, 16, and 23, the wireless communication device further includes a baseband 700, which is used to control the electrical connection or disconnection between the multi-function unit 120 and the control circuit 610. When the multi-function unit 120 is multiplexed as the reflection unit 110 and used to reflect 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 is multiplexed as the antenna unit 901 or the metasurface unit 130, the baseband 700 controls the electrical disconnection between the multi-function unit 120 and the control circuit 610. The electrical connection and disconnection here refer to electrical connection and disconnection in terms of electrical connection. When the multi-function unit 120 and the control circuit 610 are electrically connected, the control circuit 610 changes 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.

[0207] When the multi-function unit 120 is the first multi-function unit 120a and is multiplexed as the metasurface unit 130, the first multi-function unit 120a can improve the performance of the wireless signal received and transmitted by the antenna unit 901. When the multi-function unit 120 is the second multi-function unit 120b and is multiplexed as the antenna unit 901, the second multi-function unit 120b can also transmit and receive antenna signals. When the multi-function unit 120 transmits and receives antenna signals and reflects wireless signals, the magnitude of the current flowing through the multi-function unit 120 is different. Therefore, by comparing the current flowing through the multi-function unit 120, it is possible to determine whether the multi-function unit 120 is in the working state of the metasurface unit 130 or the antenna unit 901, or is processing the working state of the reflection unit 110.

[0208] 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.

[0209] Optionally, when the wireless communication device includes a circuit board 500 connected to the display panel assembly 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.

[0210] In other optional embodiments, as described above, the display panel assembly 10 further includes a second reflection unit 112, and the baseband 700 is further used to obtain the first RF operating current of the multi-function unit 120 and the second RF operating current of at least one second reflection unit 112. 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.

[0211] When the multi-function unit 120 is multiplexed into the antenna assembly 900 or the metasurface unit 130, the RF operating current in the multi-function unit 120 is different from the RF operating current in the second reflective unit 112, 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 difference between the RF operating currents of the multi-function unit 120 and the second reflective unit 112 is too large. The multi-function unit 120 is multiplexed into the antenna assembly 900 or the metasurface unit 130. 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.

[0212] The first preset threshold can be set according to the actual usage needs of the user, and can be determined jointly 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 or the metasurface unit 130 rather than the reflection surface component.

[0213] 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 current difference is less than the first preset threshold, it indicates that the RF operating current of the multi-function unit 120 and the RF operating current of the second reflector unit 112 are substantially similar, and the multi-function unit 120 is multiplexed as the reflector unit 110 and reflects wireless signals together with the second reflector unit 112. Therefore, the multi-function unit 120 is electrically connected to the control circuit 610, and the control circuit 610 can control the operating state of the multi-function unit 120 when it is multiplexed as the reflector unit 110.

[0214] Optionally, the second RF operating current acquired by the baseband 700 is the RF operating current of the second reflector unit 112 adjacent to the multi-function unit 120. That is, the acquisition unit is configured to acquire the first RF operating current of the multi-function unit 120 and the second RF operating current of the second reflector unit 112 adjacent to the multi-function unit 120. Determining whether the multi-function unit 120 is multiplexed as a reflector surface based on the RF operating current of the second reflector unit 112 adjacent to the multi-function unit 120 can improve determination accuracy, thereby improving control accuracy of the baseband 700.

[0215] 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 second reflector unit 112 and the baseband 700 to reduce the impact of noise signals on control accuracy. The baseband 700 is configured to control the electrical connection or disconnection between the multi-function unit 120 and the control circuit 610 via 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 second reflector unit 112 and the baseband 700, or both between the multi-function unit 120 and the baseband 700 and the second reflector unit 112 and the baseband 700. Optionally, the wireless communication device further includes a filter 710 connected between the multi-function unit 120 and / or the second reflector unit 112 and the baseband 700.

[0216] The control circuit 610 can be configured in various 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 second reflector unit 112 and the baseband 700. When the control circuit 610 is used to change the electrical load of 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 electrical load on the multi-function unit 120 can be adjusted. When the control circuit 610 is used to control the second reflector unit 112, the variable resistor 611 is connected between the second reflector unit 112 and the baseband 700. By changing the resistance value of the variable resistor 611, the amplitude of the electrical load on the second reflector unit 112 can be adjusted.

[0217] 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 .

[0218] Optionally, when the wireless communication device includes a circuit board 500 and a display panel assembly 10 , the variable resistor 611 may be provided in the display panel assembly 10 or the circuit board 500 .

[0219] Optionally, the control circuit 610 further includes a variable capacitor 613 and / or a variable inductor 612, which are connected between the multi-function unit 120 and the variable resistor 611. The variable capacitor 613 and / or the variable inductor 612 are connected between the second reflector 112 and the variable resistor 611. When the control circuit 610 is used to change the electrical load of 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 change the electrical load of the second reflector 112, the variable capacitor 613 and / or the variable inductor 612 are connected between the second reflector 112 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 electrical load on the multi-function unit 120 and / or the second reflector 112 can be adjusted.

[0220] 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 second reflection unit 112 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 second reflection unit 112 are directly electrically connected to the variable resistor 611, or whether the multi-function unit 120 and / or the second reflection unit 112 are electrically connected to the variable resistor 611 via the variable capacitor 613, or whether the multi-function unit 120 and / or the second reflection unit 112 are electrically connected to the variable resistor 611 via the variable inductor 612.

[0221] 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 second reflecting unit 112, 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 second reflecting unit 112 and the variable resistor 611 are connected to each other.

[0222] Optionally, the control circuit 610 further includes a downconverter 615 , which is connected between the variable resistor 611 and the baseband 700 .
