[0040] 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 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 to be steered and focused toward 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 transmitting and receiving wireless signals on wireless communication equipment.

[0041] 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. This control circuit board is connected to the reflective elements and controls 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.

[0042] In order to improve the communication performance of the wireless communication device, the present application integrates the 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.

[0043] In order to better understand the present application, the multifunctional component, wireless communication device and display panel of the embodiments of the present application are described in detail below with reference to Figures 1 to 28.

[0044] Please refer to Figures 1 to 4. Figure 1 is a schematic diagram of the structure of a wireless communication device provided in an embodiment of the present application. Figure 2 is a schematic diagram of the structure of a display panel 10 of a wireless communication device provided in an embodiment of the present application. Figure 3 is a cross-sectional view taken at AA in Figure 2, and Figure 4 is a cross-sectional view taken at BB in Figure 2.

[0045] As shown in Figures 1 to 4, an embodiment of the first aspect of the present application provides a wireless communication device, which includes a substrate 11, a functional layer 100, a shielding layer 200 and a control component 600. The functional layer 100 is arranged on the substrate 11 and includes a plurality of multi-functional units 120; the shielding layer 200 is arranged on the side of the functional layer 100 facing the substrate 11; the control component 600 is arranged on the substrate 11 and includes a radio frequency circuit 620 and a control circuit 610. The radio frequency circuit 620 is connected to the multi-functional unit 120 to control the wireless signal of the multi-functional unit 120 to receive and transmit the antenna, and the control circuit 610 is connected to the multi-functional unit 120 to change the electrical load of the multi-functional unit 120 and thereby regulate its reflected signal.

[0046] In the wireless communication device provided in the embodiment of the present application, the wireless communication device includes a substrate 11, a functional layer 100, a shielding layer 200, and a control component 600. A multi-function unit 120 is provided within the functional layer 100. The multi-function unit 120 is connected to the radio frequency circuit 620 and the control circuit 610 of the control component 600, so that the control circuit 610 can change the electrical load of the multi-function unit 120 and thereby regulate its reflected wireless signal. The radio frequency circuit 620 can control the wireless signal transmitted and received by the antenna of the multi-function unit 120. The multi-function unit 120 has both reflective and antenna functions, which can effectively improve the wireless communication performance of the wireless communication device. The shielding layer 200 is provided on the side of the functional layer 100 facing away from the display surface of the wireless communication device. The shielding layer 200 can block and reflect wireless signals, thereby causing the wireless signals to be reflected from the multi-function unit 120 and reducing the impact of wireless signals on components within the wireless communication device.

[0047] Optionally, the shielding layer 200 may be used as the metal plate in the above-mentioned IRS to shield and reflect wireless signals.

[0048] 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.

[0049] Optionally, the multi-function unit 120 is located in the display area of ​​the wireless communication device, and both the multi-function unit 120 and the shielding layer 200 are transparent structural layers. For example, the transmittance of the multi-function unit 120 and the shielding layer 200 is greater than or equal to 50%, thereby reducing the impact of the multi-function unit 120 on the display effect of the wireless communication device. In other embodiments, when the multi-function unit 120 is located in the non-display area of ​​the wireless communication device, the transmittance of the multi-function unit 120 is not limited.

[0050] The display surface of the wireless communication device, i.e., the light-emitting surface of the wireless communication device, is located closer to the functional layer 100 than the shielding layer 200. When a wireless signal enters the light-emitting surface of the wireless communication device, it first enters the functional layer 100 and is reflected by the multi-function units 120 of the functional layer 100. Some of the wireless signal then passes through the gaps between adjacent multi-function units 120 and enters the shielding layer 200, where it is blocked.

[0051] Optionally, the wireless communication device includes a display panel 10, and the substrate 11, functional layer 100, and shielding layer 200 can be disposed on the display panel 10 to integrate the multi-function unit 120 and shielding layer 200 into the display panel 10, thereby simplifying the structure of the wireless communication device. Optionally, at least part of the control circuit 610 and the radio frequency circuit 620 can also be disposed within the display panel 10, or the wireless communication device further includes a circuit board 500 connected to the display panel 10, and the control circuit 610 and the radio frequency circuit 620 can be disposed on the circuit board 500.

[0052] Optionally, each multi-function unit 120 is connected to at least one control circuit 610, and different multi-function units 120 are connected to different control circuits 610, so that each multi-function unit 120 is separately controlled by the control circuit 610. Optionally, each multi-function unit 120 is connected to at least one radio frequency circuit 620, and different multi-function units 120 are connected to different radio frequency circuits 620, so that each multi-function unit 120 is separately controlled by the radio frequency circuit 620.

[0053] Optionally, the orthographic projections of the two or more multi-function units 120 on the substrate 11 are located within the orthographic projection of the shielding layer 200 on the substrate 11 .

[0054] In some optional embodiments, as shown in FIG2 , the wireless communication device further includes a reflection group, comprising a plurality of reflection units 110. The reflection units 110 are connected to a control circuit 610, and the control circuit 610 is configured to change the electrical load of the reflection units 110. Alternatively, the reflection group is formed by combining a plurality of reflection units 110. Alternatively, each reflection unit 110 and each multi-function unit 120 are connected to a different control circuit 610. For example, each reflection unit 110 and each multi-function unit 120 are connected to a control circuit 610, and 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. In these optional embodiments, by adding a reflection unit 110 solely for reflecting wireless signals, the wireless communication performance of the wireless communication device can be further improved.

[0055] Optionally, when the wireless communication device includes a display panel 10 , the reflection group (ie, the reflection unit 110 ) may be disposed within the display panel 10 .

[0056] Optionally, the orthographic projection of the reflective unit 110 on the substrate 11 is located within the orthographic projection of the shielding layer 200 on the substrate 11 , so that the shielding layer 200 can also shield wireless signals that are not reflected by the reflective unit 110 .

[0057] In some optional embodiments, multiple reflective units 110 within a reflective group are arranged in an array, with the multi-function unit 120 located on at least one side of the reflective group in a circumferential direction. Specifically, the multi-function unit 120, which functions as both an antenna and a reflective surface, is located on the periphery of the reflective group solely for reflecting wireless signals. The multi-function unit 120 is positioned closer to the edge of the wireless communication device to minimize its impact on the display quality of the wireless communication device. As shown in FIG2 , the multi-function unit 120 is located on one side of the multiple reflective units 110 in a first direction.

[0058] Optionally, at least some of the multi-function units 120 and the reflective units 110 are arranged on the same layer, for example, all of the multi-function units 120 and the reflective units 110 are arranged on the same layer, and the reflective units 110 are also arranged on the functional layer 100, so that the multi-function units 120 and the reflective units 110 can be prepared and formed in the same process step, which can simplify the preparation process of the wireless communication device.

[0059] Optionally, as shown in Figure 2, the orthographic projection size and shape of the multi-function unit 120 set on the same layer on the substrate 11 are the same as the orthographic projection size and shape of the reflective unit 110 on the substrate 11, so as to simplify the shape arrangement of the multi-function unit 120 and the reflective unit 110 set on the same layer.

[0060] Optionally, the reflective unit 110 is disposed in the display area of ​​the wireless communication device, and the transmittance of the reflective unit 110 is greater than or equal to 50%, thereby reducing the impact of the reflective unit 110 on the display effect of the wireless communication device. In other embodiments, when the reflective unit 110 is disposed in the non-display area of ​​the wireless communication device, the transmittance of the reflective unit 110 is not limited.

[0061] In some optional embodiments, as shown in Figures 1 to 5, 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, 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.

[0062] 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 multi-function unit 120 and the control circuit 610 to connect or disconnect the electrical frequency band for a period of time t1, then controls the multi-function unit 120 and the control circuit 610 to disconnect for a period of time t2, and then controls the multi-function unit 120 and the control circuit 610 to connect for a period of time t1, and so on. The period of time t1 and the period of time t2 can be the same or different.

[0063] 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 circuit boards 500.

[0064] In other optional embodiments, 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 reflection unit 110, and the baseband 700 is further used to control the multi-function unit 120 and the control circuit 610 to disconnect 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.

[0065] When the multi-function unit 120 is multiplexed as an antenna, the RF operating current in the multi-function unit 120 is different from the RF operating current in 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, it indicates that the RF operating current of the multi-function unit 120 and the reflector unit 110 differ too much, and the multi-function unit 120 is multiplexed as an antenna. 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 is in the antenna operating mode.

[0066] The first preset threshold can be set according to the actual usage requirements of the user. For example, it can be determined based on the dynamic range of the RF device connected to the multi-function unit 120, the dynamic range of the RF device connected to the frequency band of the band reflection unit 110, and the sensitivity of the baseband 700 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 multiplexed as an antenna rather than a reflecting surface.

[0067] 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 operating current of the multi-function unit 120 and the operating current of the reflector unit 110 are substantially similar, and the multi-function unit 120 is multiplexed as a reflective surface 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.

[0068] Optionally, the second RF operating current acquired by the baseband 700 is the RF operating current of the reflector unit 110 adjacent to the multi-function unit 120. That is, the baseband 700 is configured to acquire 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 RF 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.

[0069] In some optional embodiments, the wireless communication device further includes a low-noise amplifier 720, which is 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. Optionally, the baseband 700 is further configured to control the electrical connection or disconnection between the control circuit 610 and the multi-function unit 120 through 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 between the reflector unit 110 and the baseband 700.

[0070] Optionally, the wireless communication device further includes a filter 710 connected between the multi-function unit 120 and the low noise amplifier 720 .

[0071] The control circuit 610 can be configured in a variety of ways. In some optional embodiments, as shown in FIG5 , 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 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 magnitude of the electrical load of the multi-function unit 120 when it is on the reflective surface is adjusted. When the control circuit 610 is used to change the electrical load of the reflector unit 110, the variable resistor 611 is connected between the reflector unit 110 and the baseband 700. The magnitude of the reflector unit 110 can be adjusted by changing the resistance value of the variable resistor 611. Optionally, the baseband 700 is connected to the variable resistor 611, enabling the baseband 700 to adjust the resistance value of the variable resistor 611.

[0072] 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 .

[0073] 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 .

[0074] 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 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 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 electrical phase of the multi-function unit 120 and / or the reflector unit 110 can be changed. Optionally, the baseband 700 is connected to the variable capacitor 613 so that the baseband 700 can adjust the capacitance value of the variable capacitor 613. Optionally, the baseband 700 is connected to the variable inductor 612 so that the baseband 700 can adjust the capacitance value of the variable inductor 612.

[0075] 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 connected to each other through. For example, the second switch 614 is used to control the multi-function unit 120 and / or the reflection unit 110 to be directly connected to the variable resistor 611, or the second switch 614 is used to control the multi-function unit 120 and / or the reflection unit 110 to be connected to the variable resistor 611 via the variable capacitor 613, or the second switch 614 is used to control the multi-function unit 120 and / or the reflection unit 110 to be connected to the variable resistor 611 via the variable inductor 612.

[0076] For example, the second switch 614 includes two single-pole multi-throw switches, 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 connected to the variable resistor 611, another line is connected to the variable resistor 611 via the variable capacitor 613, and the last line is connected to the variable resistor 611 via the variable inductor 612. By controlling the connectivity 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.

[0077] Optionally, the control circuit 610 further includes a downconverter 615 , which is connected between the variable resistor 611 and the baseband 700 .

[0078] Optionally, the wireless communication device includes a control line 300, through which the multi-function unit 120 is connected to the control circuit 610. Optionally, the wireless communication device also includes a radio frequency line 810, through which the multi-function unit 120 is connected to the radio frequency circuit 620. As shown in Figures 2 to 4, the multi-function unit 120 is arranged on the same layer as the control line 300 and / or the radio frequency line 810.

[0080] Optionally, the multi-function control feeder 820 and the multi-function unit 120 may be provided on the same layer to simplify the number of layer structures of the wireless communication device.

[0081] Alternatively, optionally, the multi-function control feeder 820 and the multi-function unit 120 may be arranged in different layers, so that the arrangement of the multi-function unit 120 and the arrangement of the multi-function control feeder 820 do not affect each other.

To simplify the structure of the wireless communication device, the multi-function units 120 connected to the RF line 810 and the multi-function control feeder 820 may be different. Optionally, the multi-function units 120 connected to the RF line 810 are also connected to the control line 300. That is, among the multiple multi-function units 120, some multi-function units 120 are connected to the RF circuit 620 and the control circuit 610 via the multi-function control feeder 820, while another portion of the multi-function units 120 are connected to the RF circuit 620 via the RF line 810 and to the control circuit 610 via the control line 300.

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 within the display panel 10 is connected to the RF circuit 620 and the control circuit 610, respectively, via the first signal line L1 and the second signal line L2 on the circuit board 500.

[0086] Optionally, as shown in Figures 12 to 14 , the circuit board 500 may be a flexible circuit board. The circuit board 500 is bent so that the control circuit 610 and the RF circuit 620 can be disposed on the non-display side of the wireless communication device by bending the flexible circuit board. This increases the display panel 10's occupancy rate on the wireless communication device.

On the other hand, the sizes of the first reflective unit 111 and the second reflective unit 112 are different, so they can reflect wireless signals of multiple frequency bands, allowing the display screen 10 to control the reflected signals for wireless signals of different frequency bands.

[0097] Optionally, the orthographic projections of each first multi-function unit 121 on the substrate 11 and the orthographic projections of each second multi-function unit 122 on the substrate 11 are arranged to at least partially overlap.

As shown in Figure 22, the multi-function unit 120 and the multi-function control feeder 820 can be arranged on the same layer and both located on the signal line layer 11a to simplify the structure of the display panel 10.

The extension direction of the grid metal wiring intersects with the length direction of the display panel 10, that is, the extension direction of the first signal line and / or the second signal line intersects with the extension direction of the first side, which can reduce the influence of the grid metal wiring on the display effect of the display panel 10. As shown in FIG25 , when the extension direction of the grid metal wiring intersects with the length direction of the display panel 10, the multi-function unit 120 may also be connected to two multi-function control feeders 820.

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.
