[0039] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0040] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means that the related objects before and after are in an "or" relationship.

[0041] The following will, with reference to the accompanying drawings, describe in detail the display screen, electronic device, and LED display device provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0042] Referring to Figures 1-13 , a display screen 400 provided in an embodiment of the present application may include a lamp board 100, a shielding member 200, and a bottom case 300. The shielding member 200 may be disposed between the lamp board 100 and the bottom case 300 to play an electromagnetic shielding role.

[0043] The shielding member 200 may include a conductive shielding layer 210. The lamp board 100 may be electrically connected to the conductive shielding layer 210. A grounding element 340 may be provided on the bottom case 300. The conductive shielding layer 210 or the lamp board 100 may be electrically connected to the grounding element 340 to achieve grounding of the conductive shielding layer 210. In this way, the connection between the conductive shielding layer 210 and the lamp board 100 can play an electromagnetic shielding role, so that the electromagnetic interference generated by the lamp board 100 will not spread outwards, effectively shielding the electromagnetic radiation generated when the display screen 400 works to avoid interfering with other circuits, and can shield external interference signals to avoid external interference signals from interfering with the lamp board 100, thereby ensuring that the display screen 400 can work properly.

[0044] Here, the conductive shielding layer 210 may be made of a thin and light conductive metal sheet. Specifically, the conductive shielding layer 210 may be made of aluminum foil, copper foil, etc.

[0045] Such as Figure 6As shown, the shielding member 200 may further include an insulating isolation layer 220. The insulating isolation layer 220 may cover the side of the conductive shielding layer 210 close to the lamp board 100. In this way, it can effectively prevent the conductive shielding layer 210 from being connected to the devices on the lamp board 100, thus causing a short circuit, reducing the risk of short circuit of the display screen 400, and improving the safety performance of the display screen 400.

[0046] In an alternative embodiment of the present application, the conductive shielding layer 210 may be a mesh structure. In this way, the weight of the shielding member 200 can be reduced, and thus the overall weight of the display screen 400 will not be increased. Moreover, at least some of the mesh holes 230 of the mesh structure may be first avoidance holes, and the first avoidance holes may be used to avoid the devices on the lamp board 100. In this way, it can be avoided that the devices on the lamp board 100 come into contact with the conductive shielding layer 210, resulting in a short circuit or wear, and it is beneficial to reduce the distance between the shielding member 200 and the lamp board 100, so as to be more conducive to reducing the thickness of the display screen 400 and making the display screen 400 thinner and lighter.

[0047] Here, the first avoidance holes can avoid the devices on the lamp board 100 that are relatively high in height in the thickness direction of the lamp board 100.

[0048] It should be noted that the mesh density of the conductive shielding layer 210 is related to the size of the lamp board 100, the routing and parameters of the internal circuit, etc. Moreover, the external shape and size of the shielding member 200 can be determined according to the specific shielding area required and the size of the exposed area formed after the display screen 400 is installed in the housing 500 of the electronic device.

[0049] In other embodiments, the conductive shielding layer 210 may not be set as a mesh structure. For example, it may be set as a plate-like structure without mesh holes.

[0050] In an alternative embodiment, the shape of the mesh holes 230 may be circular, triangular, square, pentagonal, etc. As Figure 4 and Figure 7 shown, optionally, the mesh holes 230 may be square holes, and the length of the diagonal of the mesh holes 230 may be less than or equal to 70 mm. In this way, the hollowed-out area of the shielding member can be made smaller, and then the part used to achieve the shielding effect is as much as possible, so as to ensure that the conductive shielding layer 210 captures most of the electromagnetic signals, thereby ensuring the shielding performance of the conductive shielding layer 210.

[0051] Of course, the length of the diagonal of the mesh holes 230 may be greater than 70 mm, or the mesh holes 230 may be circular holes, and the diameter of the mesh holes 230 may be greater than 70 mm.

[0052] In an alternative embodiment, the insulating isolation layer 220 may cover the side of the conduction shielding layer 210 close to the lamp board 100. In this way, the insulation effect can be improved to further reduce the risk of short circuit in the display screen 400. Here, the insulating isolation layer 220 may cover the entire area of the side of the conduction shielding layer 210 close to the lamp board 100 to enhance the strength of the conduction shielding layer 210. It should be noted that the entire area of the side of the conduction shielding layer 210 close to the lamp board 100 refers to the entire area of the remaining solid part of the conduction shielding layer 210 after the mesh holes 230 are formed, close to the lamp board 100. Optionally, the insulating isolation layer 220 may further cover some of the mesh holes 230 on the conduction shielding layer 210. For example, the insulating isolation layer 220 may cover the mesh holes 230 opposite to the part of the lamp board 100 without components. In this way, the strength of the conduction shielding layer 210 can be further enhanced to prevent the conduction shielding layer 210 from deforming, and there will be no interference with the components on the lamp board 100.

[0053] Certainly, the insulating isolation layer 220 may also only cover a part of the conduction shielding layer 210, and the coverage area of the insulating isolation layer 220 may be greater than or equal to half of the area of the conduction shielding layer 210, and further, may be less than or equal to twice the area of the conduction shielding layer 210. In this way, on the basis of ensuring the strength of the conduction shielding layer 210, the insulation effect can be ensured and the weight of the display screen 400 can be reduced. It should be noted that the area of the conduction shielding layer 210 here refers to the area of the side of the conduction shielding layer 210 close to the lamp board 100. Specifically, in order to ensure the strength of the conduction shielding layer 210, the insulating isolation layer 220 may include an annular insulating layer and a strip-shaped insulating layer. The annular insulating layer covers the circumferential edge of the conduction shielding layer 210, and the strip-shaped insulating layer covers some ribs of the conduction shielding layer 210. For example, multiple strip-shaped insulating layers may be distributed in a "well" shape.

[0054] Alternatively, the insulating isolation layer 220 may also only cover the part of the conduction shielding layer 210 opposite to the components on the lamp board 100. In this way, it is beneficial to reduce the weight of the shielding member 200.

[0055] In some embodiments, the insulating isolation layer 220 may be bonded to the conduction shielding layer 210 through an adhesive. Certainly, the insulating isolation layer 220 may also not be bonded to the conduction shielding layer 210 through an adhesive. Specifically, the insulating isolation layer 220 may be fixed to the conduction shielding layer 210 by fixing nails such as screws or pins or directly injection-molded on the conduction shielding layer 210.

[0056] Here, the insulating isolation layer 220 can be made of a plastic material or other insulating materials, and the insulating isolation layer 220 can have a certain strength, which can improve the rigidity of the entire shielding member 200, making the shielding member 200 unable to be bent randomly, and at the same time facilitating the thermal fusion connection between the shielding member 200 and the thermal fusion posts 310 described below.

[0057] In an alternative embodiment, the shielding member 200 can be mounted on the bottom case 300. Specifically, multiple connection holes 250 can be provided on one of the shielding member 200 and the bottom case 300, and multiple thermal fusion posts 310 can be provided on the other. Each thermal fusion post 310 can correspond to and be connected to each connection hole 250 respectively to achieve the connection between the shielding member 200 and the bottom case 300. Of course, the shielding member 200 can also be connected to the bottom case 300 by screws or the like.

[0058] In this embodiment, multiple thermal fusion posts 310 can be provided on the bottom case 300, and multiple connection holes 250 can be provided on the shielding member 200. Here, after each thermal fusion post 310 passes through the connection hole 250, the thermal fusion post 310 can be thermally fused so that each thermal fusion post 310 is connected to the hole wall of the connection hole 250 to form an integral structure, or each thermal fusion post 310 is thermally fused to the insulating isolation layer 220 of the shielding member 200 to form an integral structure, thereby realizing the connection between the shielding member 200 and the bottom case 300.

[0059] Optionally, the lamp board 100 can be connected to the bottom case 300 by screws.

[0060] It should be noted that the above bottom case 300 can be made of an insulating material. Specifically, the bottom case 300 can be made of a plastic material.

[0061] In an alternative embodiment of the present application, as Figure 3 shown, a first elastic piece 111 and a second elastic piece 112 can be provided on the lamp board 100. Both the first elastic piece 111 and the second elastic piece 112 can be electrically connected to the internal circuit of the lamp board 100, and the first elastic piece 111 can be electrically connected to the conducting shielding layer 210, and the second elastic piece 112 can be electrically connected to the grounding element 340. In this way, due to the elastic action of the first elastic piece 111 and the second elastic piece 112 themselves, there can be an active compression margin between the first elastic piece 111 and the conducting shielding layer 210 and between the second elastic piece 112 and the grounding element 340 to adapt to different gap sizes between the lamp board 100 and the conducting shielding layer 210, and a certain assembly tolerance can be overcome to ensure the reliability of the electrical connection.

[0062] In other embodiments, the lamp board 100 can be electrically connected to the conducting shielding layer 210 through a first connecting member, and the lamp board 100 can be electrically connected to the grounding element 340 through a second connecting member, and neither the first connecting member nor the second connecting member has elasticity.

[0063] In an alternative embodiment, as Figures 1-3 shown, at least two sets of elastic sheet components 110 may be provided in the edge region of the lamp board 100. Each elastic sheet component 110 may be circumferentially distributed along the lamp board 100, and each elastic sheet component 110 may include a first elastic sheet 111 and a second elastic sheet 112 arranged side by side. In this way, the number of connection points between the lamp board 100 and the shielding member 200 can be increased, which is beneficial to improving the shielding effect and the shielding uniformity of the shielding member 200. In addition, devices are prohibited from being arranged in the peripheral region of the elastic sheet component 110 on the lamp board 100, and when the lamp board 100 is connected to the shielding member 200, it is not easy for the conducting shielding layer 210 of the shielding member 200 to come into contact with the device and cause a short circuit.

[0064] Moreover, the distance between the first elastic sheet 111 and the second elastic sheet 112 may be less than a preset value. In this way, it is convenient for the first elastic sheet 111 and the second elastic sheet 112 to be connected to the internal circuit of the lamp board 100, and it is also convenient for arranging the elastic sheet component 110.

[0065] It should be noted that the number of the elastic sheet components 110 can be determined according to the actually required shielding effect.

[0066] Of course, only one set of elastic sheet components 110 may be provided at the edge of the lamp board 100.

[0067] In an alternative embodiment of the present application, the shielding member 200 may further include a conductive portion 240. Along the direction perpendicular to the thickness direction of the shielding member 200, the conductive portion 240 protrudes from the shielding member 200, and the conductive portion 240 may be electrically connected to the conducting shielding layer 210 and the lamp board 100 respectively. In this way, it is convenient to realize the electrical connection between the conducting shielding layer 210 and the lamp board 100.

[0068] Moreover, the conductive portion 240 may be a bent structure. In this way, the conductive portion 240 can be bent to the side of the conducting shielding layer 210 close to the lamp board 100, so that the conductive portion 240 can directly contact the first elastic sheet 111 on the lamp board 100. Specifically, as Figure 6 shown, the conductive portion 240 includes a first portion 241 and a second portion 242 connected to the first portion 241 and bent relative to the first portion 241. The first portion 241 is connected to the conducting shielding layer 210 through a conductive adhesive, and the second portion 242 is bent to the side of the conducting shielding layer 210 close to the lamp board 100.

[0069] Here, the conductive portion 240 can be made of conductive cloth, conductive foam, etc.

[0070] In other embodiments, the shielding member 200 may not be provided with the conductive portion 240, and the lamp board 100 and the conducting shielding layer 210 may be electrically connected through a wire.

[0071] Optionally, asFigure 7 and Figure 8 As shown in Figure 8 , the shielding member 200 may include a plurality of conductive portions 240, and the plurality of conductive portions 240 may be circumferentially distributed along the shielding member 200. In this way, the connection stability between the shielding member 200 and the lamp board 100 can be improved, and the shielding effect of the shielding member 200 and the shielding uniformity of the shielding member 200 can be improved.

[0072] It should be noted that the number of the conductive portions 240 may be determined according to the shielding level required by the display screen 400. Here, the number of the conductive portions 240 is not specifically limited.

[0073] Of course, the shielding member 200 may include only one conductive portion 240.

[0074] In an alternative embodiment, the plurality of conductive portions 240 may include at least one intermediate conductive portion 2401. The intermediate conductive portion 2401 may be connected to the edge of the conducting shielding layer 210, and the intermediate conductive portion 2401 may be located at the middle position of the edge of the conducting shielding layer 210. Specifically, the intermediate conductive portion 2401 is connected to the middle region of the edge of the conducting shielding layer 210. In this way, it is beneficial to improve the connection stability and balance between the conducting shielding layer 210 and the lamp board 100. Of course, the plurality of conductive portions 240 may also not include the intermediate conductive portion 2401.

[0075] Moreover, the intermediate conductive portion 2401 may be provided with a second avoidance hole 2402, and the second avoidance hole 2402 may be used to avoid components on the lamp board 100. In this way, it is convenient to arrange the shielding member 200, and it is beneficial to reduce the gap between the lamp board 100 and the shielding member 200, thereby being beneficial to reducing the thickness of the display screen 400. Of course, the intermediate conductive portion 2401 may also not be provided with the second avoidance hole 2402.

[0076] In an alternative embodiment of the present application, the grounding element 340 may be a telescopic structure. The grounding element 340 may include a needle body 341 and a needle head 342. The needle head 342 is telescopically arranged on the needle body 341 and is electrically connected to the needle body 341. Specifically, the grounding element 340 may be a spring needle, and the needle head 342 may be electromechanically connected to the needle body 341 through an elastic member. The needle body 341 may be connected to the bottom case 300, the needle head 342 may protrude from the bottom case 300 in a direction away from the lamp board 100, and the needle body 341 may be electrically connected to the lamp board 100, and the needle head 342 may be used for grounding. In this way, the needle head 342 can be adjusted according to the planar depth of the grounding end to be connected, so that the adaptability of the grounding element 340 is better and the error tolerance rate is higher. Moreover, when the needle head 342 is electromechanically connected to the needle body 341 through an elastic member, the grounding reliability of the needle head is higher under the elastic pressing action of the elastic member.

[0077] Here, the needle 342 may contact a ground terminal on the housing 500 of the electronic device.

[0078] In other embodiments, the grounding element 340 may be a non-stretchable conductive structure.

[0079] Optionally, the surface of the grounding element 340 can be provided with a plating layer. Specifically, the surfaces of the needle body 341 and the needle head 342 of the grounding element 340 can be provided with a plating layer. In this way, the grounding element 340 can be prevented from rusting, which is beneficial to extending the service life of the grounding element 340 and making the display screen 400 suitable for indoor and outdoor scenes.

[0080] In an optional embodiment, if Figure 10 and Figure 11 As shown, the bottom shell 300 may be provided with a mounting hole 330, the grounding element 340 may be provided in the mounting hole 330, the needle body 341 may be provided with a lap platform 343, the lap platform 343 may be provided at the end of the needle body 341 away from the needle head 342, the lap platform 343 may be electrically connected to the light board 100, and the lap platform 343 may be exposed on the side of the bottom shell 300 close to the light board 100, so that the lap platform 343 is easy to contact with the second elastic sheet 112 described above. The needle body 341 may also be provided with a waterproof platform 345, the waterproof platform 345 may be provided on the side wall of the needle body 341, and the waterproof platform 345 protrudes relative to the side wall of the needle body 341, and is sealed and connected with the hole wall of the mounting hole 330. In this way, the waterproof platform 345 can play a preliminary water-blocking role to prevent external water or dust from entering the mounting hole 330 , and further prevent external water or dust from entering the side of the bottom shell 300 close to the lamp board 100 through the mounting hole 330 .

[0081] Of course, the overlapping platform 343 and the waterproof platform 345 may not be provided on the needle body 341 .

[0082] Optionally, a fixing platform 344 may be provided on the side wall of the needle body 341, the fixing platform 344 may be located between the overlapping platform 343 and the waterproof platform 345, the fixing platform 344 may protrude relative to the side wall of the needle body 341, and the needle body 341, the fixing platform 344 and the hole wall of the mounting hole 330 may be connected to form an integrated structure by injection molding. In this way, the connection strength between the needle body 341 and the bottom shell 300 may be improved, and since the fixing platform 344 protrudes relative to the side wall of the needle body 341, the connection area between the needle body 341 and the injection molding may be increased, thereby improving the stability of the grounding element 340.

[0083] Here, one fixing platform 344 or at least two fixing platforms 344 can be provided on the side wall of the needle body 341, and the cross-sectional area of the fixing platform 344 can be less than or equal to the cross-sectional area of the waterproof platform 345. When the cross-sectional area of the fixing platform 344 is equal to the cross-sectional area of the waterproof platform 345, the contact area between the injection plastic and the fixing platform 344 can be increased, thereby improving the connection strength between the grounding element 340 and the bottom case 300; when the cross-sectional area of the fixing platform 344 is less than the cross-sectional area of the waterproof platform 345, it is convenient to place the grounding element 340 in the cavity of the injection mold. Of course, the cross-sectional area of the fixing platform 344 can also be greater than the cross-sectional area of the waterproof platform 345.

[0084] Optionally, the cross-sectional area of the overlapping platform 343 can be greater than or equal to the cross-sectional area of the fixing platform 344. In this way, it is beneficial to ensure the contact area between the grounding element 340 and the second elastic piece 112, and thus beneficial to improving the electrical conduction reliability between the grounding element 340 and the second elastic piece 112. Of course, the cross-sectional area of the overlapping platform 343 can also be less than the cross-sectional area of the fixing platform 344.

[0085] In other embodiments, the fixing platform 344 may not be provided on the side wall of the needle body 341, and the needle body 341 is not connected to the hole wall of the mounting hole 330.

[0086] It should be noted that the above-mentioned overlapping platform 343, fixing platform 344 and waterproof platform 345 can be circular structures or structures of other shapes, and the sizes of the overlapping platform 343, fixing platform 344 and waterproof platform 345 can be determined according to the reliability requirements of the area to be connected.

[0087] In the embodiments of the present application, as Figure 1 and Figure 2 shown, a signal connector 120, a first power connector 130 and a second power connector 140 can also be provided on the lamp board 100. The first power connector 130 and the second power connector 140 are respectively arranged on both sides of the signal connector 120, and the first power connector 130 and the second power connector 140 can be respectively electrically connected to the high-voltage end and the low-voltage end of the internal circuit of the lamp board 100. An interface 320 can also be provided on the bottom case 300. The signal connector 120 can be connected to other devices through the interface 320, and the first power connector 130 and the second power connector 140 can be connected to the power supply through the interface 320 to enable the power supply to supply electrical energy to the lamp board 100. And, an avoidance groove for avoiding the signal connector 120, the first power connector 130 and the second power connector 140 can be provided on the shielding member 200.

[0089] The shielding member 200 of the display screen 400 provided in the embodiment of the present application is overall thinner and lighter, with a maximum thickness of less than 1 mm. And the shielding member 200 is embedded inside the display screen 400, which does not affect the appearance of the display screen 400 and does not affect the overall structure of the product. The overall structure of the shielding member 200 is clear and simple, and the installation is convenient. The shielding member 200 is set as a mesh structure, which can not only reduce the weight of the shielding member 200 without increasing the overall weight of the display screen 400, but also avoid the high devices on the lamp board 100. In this way, the shielding effect on the external interference signal source is better, and the radiation escape of itself is also better, and the distance between the shielding plate and the lamp board 100 can be reduced; at the same time, since the insulating isolation layer 220 is provided on the side of the conduction shielding layer 210 of the shielding member 200 close to the lamp board 100, it can play a role of single-sided insulation, avoiding the connection between the conduction shielding layer 210 and the devices on the lamp board 100 and causing a short circuit, reducing the risk of short circuit of the display screen 400, and improving the safety performance of the display screen 400. Compared with the method of adding shielding magnetic rings on the cable or in a local area, the technical solution of the present application has a lower cost, stronger installability, and better compatibility with the product.

Here, the basic installation surface can be a wall or other installation structures. One of the bracket 600 and the housing 500 may be provided with at least one fixing member 620, and the other may be provided with at least one fixing hole 611. One end of the fixing member 620 can pass through the fixing hole 611 and be hooked to the fixing hole 611, so that the housing 500 is hooked on the bracket 600, and further the display screen 400 can be hooked on the basic installation surface. In this way, it is convenient for disassembly and assembly, and the quick installation of the display screen 400 can be realized, which is beneficial to improving the timeliness of installation.

[0094] In other embodiments, the bracket 600 and the housing 500 can be fixedly connected by fixing screws.

[0095] In an alternative embodiment, as Figure 16 shown, the fixing hole 611 may include a first through hole 6111 and two second through holes 6112, and both of the two second through holes 6112 can communicate with the first through hole 6111.

[0096] The fixing member 620 may include a hanging portion 621 and a rod portion 622 connected to the hanging portion 621. The width of the hanging portion 621 in a direction perpendicular to the connection direction of the first through hole 6111 and the second through hole 6112 is less than or equal to the aperture of the first through hole 6111 and greater than the aperture of the second through hole 6112.

[0097] Here, since the fixing hole 611 includes two second through holes 6112, and the two second through holes 6112 can be respectively located on opposite sides of the first through hole 6111, in this way, the fixing member 620 can form a hook connection with any one of the second through holes 6112. When installing the display screen 400, it is not necessary to distinguish the installation direction for installation, which is beneficial to improving the installation efficiency and making the bracket 600 have the characteristic of non-directionality during installation.
