[0003] In related technologies, to enable a display device to have multiple functions such as data download and data sharing, multiple wireless antennas need to be provided inside the display device. However, interference may occur between the signals of multiple wireless antennas, causing delays and lags in the display device and affecting the wireless performance of the display device. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a wireless component and a display device to improve the interference phenomenon between multiple wireless antennas in the display device and enhance the wireless performance of the display device. The specific technical solutions are as follows:

[0005] An embodiment of the first aspect of this application provides a wireless component applied to a display device. The wireless component includes a circuit board, at least one wireless module, at least one antenna module, and isolation traces.

The first section and the second section are located between two adjacent antennas and are oppositely disposed, and the first section and the second section are respectively connected to the ground terminals of the two antennas.

[0006] In some embodiments, along the direction perpendicular to the extension direction of the first section, the distance between the first section and the second section is 0.8 mm to 1.4 mm.

[0007] In some embodiments, each antenna module includes two antennas. The isolation traces further include a third section that is electrically connected to the first section and the second section. The third section is perpendicular to the first section and the second section. The third section and the first section define a first region, and the second section and the third section define a second region. The two antennas are respectively located in the first region and the second region.

[0008] In some embodiments, the wireless component further includes an inductor, which is serially disposed on the isolation trace, and the inductor is used to adjust the isolation frequency of the at least two antennas.

[0009] In some embodiments, the wireless component includes two wireless modules and two antenna modules, and the two antenna modules are electrically connected to the two wireless modules respectively.

[0010] In some embodiments, the two antenna modules are respectively disposed on two sides of the circuit board along the long side direction.

[0011] In some embodiments, the wireless component further includes a feeding structure, which is disposed on the circuit board and electrically connected to the at least one wireless module.

[0034] To improve the isolation between multiple wireless antennas, so as to improve the interference phenomenon between multiple wireless antennas in a display device and improve the wireless performance of the display device, the embodiments of the present application provide a wireless component, which can be applied to a display device. The wireless component and the display device provided by the present application will be described in detail below with reference to the drawings. Among them, the isolation of an antenna refers to the ratio of the signal transmitted by one antenna to the signal received by another antenna. Specifically, the less signal received by one antenna from another antenna transmitting signal, the higher the ratio of the signal transmitted by this antenna to the signal received by another antenna, the better the isolation between the two antennas, and the lower the degree of interference to the antenna.

[0035] Such as Figures 1 to 4As shown in the figure, an embodiment of the first aspect of the present application provides a wireless component 2, which includes a circuit board 200, at least one wireless module 20, at least one antenna module 21, and an isolation trace 30. At least one wireless module 20 is disposed on the circuit board 200; at least one antenna module 21 is electrically connected to at least one wireless module 20, and at least one antenna module 21 includes at least two antennas disposed on the circuit board 200. As Figure 2 shown, the isolation trace 30 is disposed on the circuit board 200, and the isolation trace 30 includes a first section 301 and a second section 302 that are electrically connected. The first section 301 and the second section 302 are located between two adjacent antennas and are oppositely arranged, and the first section 301 and the second section 302 are respectively connected to the ground terminals 2111 of the two antennas.

[0036] In the embodiment of the present application, at least one antenna module 21 includes at least two antennas disposed on the circuit board 200. The at least two antennas can be metal antennas, PCB (Printed Circuit Board) board-mounted antennas, FPC (Flexible Printed Circuit) antennas, rod-shaped external antennas, etc. The antenna form can be set according to actual needs, and the present application does not limit this. Among them, the number of antennas included in each antenna module 21 can also be set according to actual needs, and the present application does not make specific limitations on this either. For example, each antenna module 21 can include two antennas that are oppositely arranged.

[0037] In the embodiment of the present application, the isolation trace 30 is disposed on the circuit board 200. Specifically, the isolation trace 30 can be a trace printed on the circuit board 200 and can be an integral structure with the circuit board 200. The first section 301 and the second section 302 are electrically connected and are located between two adjacent antennas. Specifically, the first section 301 and the second section 302 are respectively disposed close to one antenna. Further, as Figure 2 shown, the first section 301 and the second section 302 are arranged in parallel. Among them, the first section 301 and the second section 302 are respectively connected to the ground terminals 2111 of the two antennas, that is, both ends of the isolation trace 30 are respectively connected to the ground terminals 2111 of the two antennas.

[0038] Among them, there are various connection methods between the at least two antennas included in the antenna module 21 and the circuit board 200. For example, when the at least two antennas are metal antennas, they can be connected to the circuit board 200 by welding. As Figures 4 to 7As shown, each antenna can be provided with three welding points, and the three welding points can include a grounding terminal 2111 and two feeding terminals 2112. Among them, the feeding terminal 2112 of the antenna can be used to be electrically connected to the wireless module 20, and the feeding terminal 2112 can also be electrically connected to other power supply devices to supply electrical energy to the antenna.

[0039] In the embodiments of the present application, as Figure 2 shown, two antennas are arranged adjacent to each other, and an isolation trace 30 is arranged between the two antennas. The first section 301 and the second section 302 of the isolation trace 30 are respectively connected to the grounding terminals 2111 of the two antennas. Among them, the first section 301 and the second section 302 are electrically connected and are oppositely arranged between the adjacent two antennas. Since the first section 301 and the second section 302 are respectively connected to the grounding terminals 2111 of the two antennas, during the operation of the wireless component 2, currents with opposite directions will be generated in the first section 301 and the second section 302, so that the two antennas generate radiation currents with opposite directions around the first section 301 and the second section 302, and further eliminate the mutual coupling effect generated between the adjacent two antennas through the radiation currents with opposite directions, thereby reducing the influence of the mutual coupling effect generated by the two antennas due to the too close distance on the antenna performance, improving the isolation degree between the antennas, so as to improve the interference phenomenon between multiple wireless antennas in the display device 1 and improve the wireless performance of the display device 1.

[0040] In some embodiments of the present application, along the direction perpendicular to the extension direction of the first section 301, the distance between the first section 301 and the second section 302 is 0.8 mm to 1.4 mm.

[0041] In the embodiments of the present application, as Figure 2 shown, the distance between the first section 301 and the second section 302 of the isolation trace 30 is 0.8 mm to 1.4 mm. For example, the trace width D of the isolation trace 30 at the first section 301 and the second section 302 can be 1.2 mm. The trace width D can also be set according to specific circumstances, and the present application does not limit this. Since the first section 301 and the second section 302 of the isolation trace 30 are located between the adjacent two antennas, and the trace width D of the isolation trace 30 is 0.8 mm to 1.4 mm, that is, along the direction perpendicular to the extension direction of the first section 301 or the second section 302, the distance between the two antennas is relatively large, further reducing the probability that the mutual coupling effect generated by the two antennas due to the close distance affects the antenna performance.

[0042] In some embodiments of the present application, the trace length of the isolation trace 30 can be set according to actual needs. For example, since the size of the frequency band corresponding to the isolation degree will affect the length of the isolation trace 30, the trace length can be set according to the isolation frequency band corresponding to the isolation degree required by the wireless component 2.

[0043] For example, as Figure 2 shown, at least one antenna group may include a first antenna 2101 and a second antenna 2102. The isolation requirement between the first antenna 2101 and the second antenna 2102 at the 2.4 GHz frequency band is not less than 15 dB. However, without changing the trace length of the isolation trace 30, the measured isolation after actual testing is below 10 dB, that is, the current wireless component 2 does not meet the actual design requirements. At this time, the trace length of the isolation trace 30 can be adjusted accordingly to adjust the isolation between the first antenna 2101 and the second antenna 2102. Specifically, the frequency band where the minimum isolation is located can be measured by an instrument as 2.44 GHz, and the trace length of the isolation trace 30 is adjusted to one-quarter wavelength of the 2.44 GHz frequency band, and then the isolation between the first antenna 2101 and the second antenna 2102 is tested again to see if it is improved to meet the actual design requirements. If the improvement effect is not obvious after adjustment, the length of the isolation trace 30 is finely adjusted to make the isolation greater than 15 dB so that the wireless component 2 meets the requirements.

[0044] In some embodiments of the present application, as Figure 2 and Figure 3 shown, each antenna module 21 includes two antennas. The isolation trace 30 further includes a third section 303 electrically connected to the first section 301 and the second section 302. The third section 303 is perpendicular to the first section 301 and the second section 302. The third section 303 and the first section 301 define a first region A, and the second section 302 and the third section 303 define a second region B. The two antennas are respectively located in the first region A and the second region B.

[0045] In the embodiments of the present application, as Figure 2 and Figure 3 shown, the overall shape of the isolation trace 30 can be generally T-shaped. As Figure 2 shown, the isolation trace 30 includes a first section 301, a second section 302, and a third section 303. For example, when the isolation trace 30 is T-shaped, the third section 303 is the upper part of the T, and the lower part is the first section 301 and the second section 302. The third section 303 is perpendicular to the first section 301 and the second section 302. The third section 303 and the first section 301 define a first region A, and the second section 302 and the third section 303 define a second region B. The first section 301 and the second section 302 are located between the two antennas and are oppositely arranged. Setting the third section 303 can increase the length of the isolation trace 30, and setting the two antennas in different regions defined by the isolation trace 30 can further improve the isolation of the antennas.

[0046] In the embodiments of the present application, the overall shape of the isolation trace 30 can also be linear, etc. The shape can be set according to the length of the isolation trace 30, the space between adjacent antennas, the magnitude of the required isolation degree, etc. The present application does not limit this.

[0047] In some embodiments of the present application, as Figure 3 shown, the wireless component 2 further includes an inductor 40. The inductor 40 is serially disposed on the isolation trace 30, and the inductor 40 is used to adjust the isolation frequency of at least two antennas.

[0048] In the embodiments of the present application, as Figure 3 shown, an inductor 40 can be serially disposed on the isolation trace 30. The inductor 40 is used to adjust the isolation frequency when the length of the isolation trace 30 cannot be increased due to limited space on the circuit board 200, so that the isolation frequency band of the wireless component 2 does not meet the isolation frequency band corresponding to the target isolation degree, so as to adjust the isolation degree of the wireless component 2 to the target isolation degree by adjusting the isolation frequency band. For example, if the available space or area of the circuit board 200 is small and cannot provide sufficient layout space for the isolation trace 30, or the installation area provided by the display device 1 for the wireless component 2 is small, resulting in a relatively dense arrangement of components on the wireless component 2 and a small layout space for the isolation trace 30, thus resulting in a small length of the isolation trace 30, the isolation frequency band of the wireless component 2 can be adjusted to the isolation frequency band corresponding to the target isolation degree by the inductor 40. In addition, the inductor 40 is also used to convert electrical energy into magnetic energy and store it. The inductor 40 is also used to perform functions such as filtering, oscillation, delay, and notch in the isolation trace 30, as well as functions such as signal screening, noise filtering, current stabilization, and electromagnetic wave interference suppression.

[0049] In some embodiments of the present application, as Figure 1 、 Figure 4 and Figure 5 shown, the wireless component 2 includes two wireless modules 20 and two antenna modules 21. The two antenna modules 21 are electrically connected to the two wireless modules 20 respectively.

[0050] In the embodiments of the present application, as Figure 1 、 Figure 4 and Figure 5As shown, the wireless component 2 includes two wireless modules 20, and the two wireless modules 20 include a first wireless module 201 and a second wireless module 202. The two wireless modules 20 can be in different working states. For example, when the first wireless module 201 is a terminal, the second wireless module 202 can be a hotspot; when the first wireless module 201 is a hotspot, the second wireless module 202 can be a terminal; the two wireless modules 20 can also both be terminals or hotspots. In addition, under the condition of meeting the usage requirements, only one wireless module 20 can be set to the working state. At this time, this wireless module 20 can be a terminal or a hotspot. That is, the user can set the working state of the wireless component 2 according to the needs to meet different application scenarios, and the present application does not limit this.

[0051] In addition, in extreme situations such as thunderstorm weather, or when the number of users is large, resulting in unstable wireless signal transmission, and states such as information transmission stop or jamming occur, the two wireless modules 20 can work together, and the two antenna modules 21 that are arranged in a matching manner and electrically connected to the two wireless modules 20 also work together, so as to enhance the wireless signal strength of the wireless component 2, make the performance of the wireless component 2 reliable and stable, and meet more usage requirements.

[0052] Among them, as Figures 4 to 7 shown, the positions of the two wireless modules 20 on the circuit board 200 can be adjusted according to the positions of each component on the circuit board 200. For example, the two wireless modules 20 can be arranged on both sides of the circuit board 200, and the two wireless modules 20 can also be arranged adjacent to each other. The present application does not limit this.

[0053] In some embodiments of the present application, as Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown, the two antenna modules 21 are respectively arranged on both sides of the circuit board 200 along the long side direction.

[0054] In the embodiments of the present application, the two antenna modules 21 include a first antenna module 211 corresponding to the first wireless module 201 and a second antenna module 212 corresponding to the second wireless module 202. The two antenna modules 21 are respectively arranged on both sides of the circuit board 200 along the long side direction. At this time, the distance between the first antenna module 211 and the second antenna module 212 is relatively large, which can reduce the probability of mutual coupling effect between the two antenna modules 21, reduce the radiation influence between the two antennas on both sides, and reduce the probability of co-frequency interference between the wireless signals generated by multiple antennas, so as to further improve the interference phenomenon between multiple wireless antennas in the display device 1 and improve the wireless performance of the display device 1.

[0055] In some embodiments of the present application, as Figure 1As shown, the wireless component 2 further includes at least one interface 240. The at least one interface 240 is disposed on the circuit board 200 and is used for electrically connecting with at least one wireless module 20 and the controller 10 in the display device 1.

[0056] In the embodiment of the present application, the at least one interface 240 is used for electrically connecting with at least one wireless module 20 and the controller 10 in the display device 1 to achieve current and data transmission between the at least one wireless module 20 and the controller 10. Specifically, as Figure 1 shown, the at least one interface 240 can receive the data sent by the controller 10 in the display device 1, then transmit the data to the wireless module 20 electrically connected thereto, and then convey it to the antenna electrically connected thereto via the wireless module 20, and then radiate it out via the antenna.

[0057] Among them, the at least one interface 240 includes but is not limited to a PCIE interface (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard), or an SDIO interface (Secure Digital Input And Output), or a USB interface (Universal Serial Bus), etc. The type of the interface 240 can be set according to actual needs, and the present application does not limit this.

[0058] In some embodiments of the present application, as Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the at least one interface 240 is disposed on a side of the at least one wireless module 20 away from the at least one antenna module 21, or the at least one interface 240 is located between the at least one wireless module 20 and the at least one antenna module 21.

[0059] In the embodiment of the present application, as Figure 4 shown, the at least one interface 240 can be disposed on a side of the at least one wireless module 20 away from the at least one antenna module 21. As Figure 5 , Figure 6 and Figure 7 shown, the at least one interface 240 is located between the at least one wireless module 20 and the at least one antenna module 21. The position of the at least one interface 240 can be set according to the shape and size of the circuit board 200 and the arrangement of the components on the wireless component 2, and the present application does not limit this.

[0060] Furthermore, the relative position of the at least one interface 240 with respect to the antenna can also be adjusted according to actual needs, such as Figure 5 and Figure 7As shown, the interface 240 can be arranged side by side with an antenna along the short side direction of the circuit board 200; as Figure 6 shown, the interface 240 can be located between the antenna module 21 and the wireless module 20, and this application does not limit this. In addition, as Figures 5 to 7 shown, the relative positions between two antennas belonging to the same antenna module 21 can also be adjusted according to requirements, and this application does not limit this either. It only needs to ensure that there is a certain gap between adjacent two antennas, and the mutual coupling effect generated due to the close distance between adjacent two antennas is small, and the probability of affecting the antenna performance is low.

[0061] In some embodiments of this application, as Figure 1 shown, the wireless component 2 further includes a feeding structure 230, and the feeding structure 230 is arranged on the circuit board 200 and electrically connected to at least one wireless module 20.

[0062] In the embodiments of this application, the feeding structure 230 can provide different working power supplies for at least one wireless module 20 according to actual requirements. At least one wireless module 20 is electrically connected to the controller 10 in the display device 1, and the display device 1 can provide part of the current for at least one wireless module 20. However, when a large amount of data needs to be transmitted between the display device 1 and the wireless component 2, and the current provided by the display device 1 is not enough to support the working requirements of at least one wireless component 2, the feeding structure 230 can provide a larger working current for at least one wireless module 20 to meet the current required for the operation of at least one wireless module 20. In addition, when the wireless component 2 includes multiple wireless modules 20, the feeding structure 230 can also provide sufficient working current for the multiple wireless modules 20.

[0063] In some embodiments, the wireless component 2 includes a housing, the housing has an accommodating space, and the circuit board 200 and each component integrated on the circuit board 200 can be placed in the accommodating space. The housing can be connected to the display device 1 through a connecting piece.

[0064] Furthermore, the housing and the connecting piece can be made of a metal material with good thermal conductivity, so that the housing and the fixing piece can also be used as heat dissipation components of the wireless component 2 to dissipate heat from the wireless component 2. In addition, a radiator can also be integrally arranged on the circuit board 200, or heat dissipation holes can be opened on the housing to further improve the heat dissipation performance of the wireless component 2.

[0065] Embodiments of the second aspect of this application provide a display device 1, as Figure 1 shown, the display device 1 includes the wireless component 2 according to any one of the above, and the display device 1 further includes a controller 10, and the controller 10 is used to be electrically connected to at least one wireless module 20 in the wireless component 2.

[0066] In the embodiments of this application, as Figure 1As shown in the figure, the display device 1 further includes a display screen 110, a camera 120, a power supply device 130, a USB HUB chip 140 (UniversAl SeriAlBus HuB, universal serial bus hub), etc. The wireless component 2 can be fixedly arranged inside the display device 1 and is an integral structure with the display device 1. The wireless component 2 can also be connected to the display device 1 as a separate wireless device accessory. When the wireless component 2 is arranged inside the display device 1, the connection manners between the wireless component 2 and the display device 1 include but are not limited to locking connection and snap connection, etc. When the wireless component 2 is connected to the display device 1 as a separate wireless device accessory, it can be connected to the display device 1 through a PCIE interface or an SDIO interface or a USB interface, etc. An interface matching the wireless component 2 is arranged on the display device 1, and the type of the interface can be set according to actual requirements, which is not limited in this application.

[0067] In the wireless component 2 of the display device 1 provided by the embodiment of the present application, the first section 301 and the second section 302 are oppositely arranged between two adjacent antennas, and the first section 301 and the second section 302 are respectively connected to the grounding ends 2111 of the two antennas. Among them, the first section 301 and the second section 302 are electrically connected and oppositely arranged between two adjacent antennas. Since the first section 301 and the second section 302 are respectively connected to the grounding ends 2111 of the two antennas, during the operation of the wireless component 2, currents with opposite directions will be generated in the first section 301 and the second section 302, so that the two antennas generate radiation currents with opposite directions around the first section 301 and the second section 302, and further eliminate the mutual coupling effect generated between the two adjacent antennas through the radiation currents with opposite directions, thereby reducing the influence on the antenna performance caused by the mutual coupling effect generated due to the too-close distance between the two antennas, improving the isolation degree between the antennas, improving the interference phenomenon among multiple wireless antennas in the display device 1, and improving the wireless performance of the display device 1.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered by the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
