[0001] This application relates to the field of LED (Light Emitting Diode) displays, and in particular, to a bonding module and Bonded display I related.

Background Art

[0002] Currently, displays used in, for example, outdoor displays, large exhibitions, conferences, etc. usually consist of a plurality of display devices with small display areas joined together to form a single large display, and each display device cooperates under the control of a controller to realize the display function. In some current joining methods, when joining two display devices, it is necessary to use a joining sheet, and due to the insufficient engagement degree between the joining sheet of the prior art and the display, it is difficult to improve the mounting efficiency.

Summary of the Invention

Means for Solving the Problems

[0003] This application provides a joining sheet for joining at least two middle frames. The middle frame has a front side where a display module is to be mounted and a rear side opposite to the front side. The outer contour of the middle frame is rectangular, and there is one vertex region at each of the four corners of the rectangle. At least one vertex region is provided with a joining sheet mounting region for engaging with the joining sheet. The joining sheet mounting region includes a pre-mounting region and a post-mounting region located on the front side and the rear side of the middle frame respectively. Both the pre-mounting region and the post-mounting region are provided with joining screw holes and positioning pin holes. The joining sheet includes a sheet body, a joining through hole and a positioning pin located on the sheet body. The positioning pin is integrally formed with the sheet body and is arranged to engage with the positioning pin hole. The joining through hole and the joining screw hole are arranged to engage with a first screw fastener so as to fasten the joining sheet and the middle frame. <​The above-mentioned joining sheet assists in joining the intermediate frame from the front or rear side. The provision of pins on the joining sheet is advantageous in improving the load-bearing capacity of the joining sheet to the intermediate frame. Furthermore, the positioning pins on the joining sheet are arranged to engage with the positioning pin holes in the intermediate frame, and the joining through-holes on the joining sheet are arranged to be fastened with the joining screw holes in the intermediate frame by the first screw fastener. When installing the joining sheet, it is not only fastened by the first screw fastener, but hole-pin engagement can also be achieved by the positioning pins and positioning pin holes. On the other hand, hole-pin engagement allows for rapid "pre-connection" between the intermediate frame and the joining sheet by quickly engaging the positioning pins with the positioning pin holes in the intermediate frame when mounting the joining sheet and the intermediate frame. This is suitable for the joining through-holes on the joining sheet to be quickly fastened with the joining screw holes in the intermediate frame by the first screw fastener by maintaining the relative positional relationship between the intermediate frame and the joining sheet before the first screw fastener functions. This facilitates the installation and locking of the first screw fastener, while simultaneously integrally molding the sheet body and positioning pin in the joining sheet. When the joining through-hole and positioning pin engage, the sheet body of the joining sheet is used as a reference to accurately determine the position of the joining through-hole and positioning pin. By using the position of the positioning pin as an engagement reference and engaging it with the positioning pin hole in the middle frame, the engagement accuracy between the joining sheet and the middle frame is improved to some extent, the degree of engagement between the joining sheet and the middle frame is improved, the joining seam is reduced, and the quality of the joining display by joining is improved.

[Modes for carrying out the invention]

[0006] Hereinafter, the present application will be described more comprehensively with reference to the relevant drawings to facilitate understanding of the present application. Preferred embodiments of the present application are shown in the drawings. However, the present application is not limited to the embodiments described herein and may be realized in many different forms. Conversely, the purpose of providing these embodiments is to provide a more complete understanding of the disclosure of the present application.

[0007] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein are solely for the purpose of describing modes for carrying out the invention and are not intended to limit this application.

[0008] Example 1 This embodiment addresses the problem of difficulty in improving installation efficiency due to insufficient engagement between the bonding sheet and the intermediate frame in the prior art by providing a bonding sheet. As shown in Figures 2 and 5, the bonding sheet 20 is for bonding at least two intermediate frames, and the intermediate frame 10 The structure is as shown in Figure 1.

[0009] In this embodiment, the inner frame 10 is also called the "housing" and has high strength and load-bearing capacity as a mounting carrier for major components such as the display module (also called the display panel), power supply, and signal adapter card in the display device. For example, in some examples, the inner frame 10 is made of metal or alloy material. The inner frame 10 has a frame structure and has four side beams 11, the four side beams 11 being at least endless so that the outer contour of the inner frame 10 forms a rectangle. The rectangular inner frame 10 has four vertices, i.e., four vertex angles, and in this embodiment, the areas corresponding to the vertex angles are referred to as "vertex angle areas". At least one of the four vertex angle areas of the inner frame 10 is provided with a bonding sheet mounting area for engaging with the bonding sheet 20, and the bonding sheet 20 is for joining at least two inner frames 10 by at least two first screw fasteners 30. Therefore, when joining the inner frames 10, the bonding sheet 20 is connected and fixed simultaneously with at least two inner frames 10. In this embodiment, the side of the middle frame 10 to which the display module is attached is referred to as the front side of the middle frame 10, and the side opposite the front side is referred to as the rear side of the middle frame 10. Typically, the rear cover of the display device is attached to the rear side of the middle frame 10.

[0010] In this embodiment, the joining sheet 20 includes a sheet-like sheet body, joining through holes and positioning pins provided in the sheet body. Refer to the schematic diagram of the connection between the joining sheet 20 and the first screw fastener 30 provided in Figure 2. The joining sheet 20 is provided with at least two screwless joining through holes 201, and these at least two joining through holes 201 correspond to at least two intermediate frames 10, refer to Figure 1 for the intermediate frames. In Figure 2, the joining sheet 20 is substantially rectangular and has four joining through holes 201 located at each of the four corners of the joining sheet, and each joining through hole 201 corresponds to one intermediate frame 10, so the joining sheet 20 shown in Figure 2 can join four intermediate frames 10. A joining screw hole 101 is provided in the joining sheet mounting area (see Figures 1 and 3), the joining screw hole 101 penetrates the front and rear sides of the middle frame 10, and the joining screw hole 101 corresponds one-to-one with the joining through hole 201, both of which engage with the first screw fastener 30, and one end of the first screw fastener 30 passes through the joining through hole 201 to the middle frame10 The joining screw holes 101 and screw connections lock the joining sheet 20 and the middle frame 10 together.

[0011] In this embodiment, referring to the areas shown by the dashed lines in Figures 1 and 3, the bonding sheet mounting area includes a pre-mounting area 100a located on the front side of the middle frame 10 and a post-mounting area 100b located on the rear side of the middle frame 10, with the pre-mounting area 100a and the post-mounting area 100b being located opposite each other. In this embodiment, when joining the middle frame 10, the bonding sheet 20 may be placed on the front side of the middle frame 10 and engaged with the pre-mounting area 100a (see Figure 4), and the bonding sheet 20 The middle frame 10 may be positioned on the rear side and engaged with the post-mount region 100b (see Figures 6-1 and 6-2). In some examples, a bonding sheet may be placed between the pre-mount region 100a and the post-mount region 100b of the middle frame 10. 20 They may be provided simultaneously. However, in the usual case, only one side of a single bonding sheet mounting area has a bonding sheet. 20 You just need to engage with it.

[0012] Referring to Figures 1 to 3, when the pre-mounting region 100a engages with the bonding sheet 20, the bonding sheet 20 is located on the front side of the middle frame 10, suitable for a scenario where the installer joins and mounts the display module from the front side of the middle frame 10. In this case, one end of the first screw fastener 30 is fastened to the bonding screw hole 101 by screw connection through the bonding through hole 201, starting from the front side of the middle frame 10 (see Figures 1 and 4). When the post-mounting region 100b engages with the bonding sheet 20, the bonding sheet 20 is located on the rear side of the middle frame 10, suitable for a scenario where the installer joins and mounts the display module from the rear side of the middle frame 10. In this case, one end of the first screw fastener 30 is fastened to the bonding screw hole 101 by screw connection through the bonding through hole 201, starting from the rear side of the middle frame 10 (see Figures 3 and 6-1, 6-2).

[0013] Continuing to refer to Figure 1, in some examples, the pre-mounting region 100a is at least partially recessed, so that when the bonding sheet 20 engages with its pre-mounting region 100a, a portion of the bonding sheet 20 fits into the pre-mounting region 100a through this recess, reducing the overall thickness after the bonding sheet and the middle frame 10 are engaged, and preventing the outward protrusion of the bonding sheet on the front side of the middle frame 10 from being too high and affecting the mounting of the display module to the front side of the middle frame 10. In some examples, the depth of the recess in the pre-mounting region 100a is greater than or equal to the thickness of the bonding sheet 20, so that the bonding sheet 20 does not protrude to the front of the middle frame 10. In any case, the bonding sheet 20 is never fully fitted into one middle frame 10, because one bonding sheet needs to engage with at least two middle frames 10 simultaneously, and therefore only a portion of it fits into each middle frame 10, at the same time, at least a portion may be exposed from the middle frame 10. However, the fitted portion may be completely fitted into the inner frame 10 when viewed from the thickness direction of the bonding sheet 20.

[0014] Continuing to refer to Figures 1 to 3, in some examples, a positioning pin hole 102 is provided in the bonding sheet mounting area of ​​the middle frame 10 for engaging with a positioning pin 202 in the bonding sheet 20. The hole-pin engagement is simple, does not require tools, and is easy to implement. When bonding the bonding sheet 20 to the bonding sheet mounting area 100 of the middle frame 10, the hole-pin engagement between the positioning pin hole 102 and the positioning pin 202 is already completed, that is, the positioning pin 202 is inserted into the positioning pin hole 102. At this time, the first screw fastener 30 has not completed engagement with the bonding screw hole 101 and the bonding through hole 201. Therefore, it is understood that the hole-pin engagement allows for initial fixing or "pre-fixing" of the bonding sheet 20 in the mounting connection area 100 before the middle frame 10 and the bonding sheet 20 are fully locked together. After the hole-pin engagement is achieved, the joining through hole 201 and the joining screw hole 101 are aligned, providing convenient conditions for engaging the first screw fastener 30 with the joining sheet 20 and the middle frame 10. In this embodiment, the engagement accuracy of the hole-pin engagement is higher than that of the screw engagement. For example, in this embodiment, the positioning pin hole 102 and the positioning pin 20 2 The gap between the first screw fastener 30 and the joining screw hole 101 is 0.15 mm, while the engagement gap between the first screw fastener 30 and the joining screw hole 101 is 0.5 mm. The function of the first screw fastener 30 and the joining screw hole 101 is to lock the joining sheet 20 and the middle frame from the axial direction of the first screw fastener 30, therefore, in terms of mounting accuracy, the positioning pin hole 102 and the positioning pin 20 2 The engagement accuracy may be lower than that of the first screw fastener 30, and during implementation, the first screw fastener 30 can be easily screwed into the joining screw hole 101 and installed quickly.

[0015] In some examples, the sheet body and positioning pin 202 in the bonding sheet 20 may be integrally molded, for example by die casting, and the quality of the bonding sheet 20 can be significantly improved by forming the bonding sheet 20 through an integral molding process. For example, in one example, the positioning pin 202 and the sheet body are integrally molded, and the diameter of the positioning pin 202 reaches 8 mm or more, thereby ensuring that the sheet body and positioning pin 202 can withstand a pressure of 500 kilograms or more.

[0016] In this embodiment, the positioning pin holes 102 provided in the bonding sheet mounting area 100 may be blind holes or through holes. If they are blind holes, the positioning pin holes 102 corresponding to the pre-mounting area 100a and the post-mounting area 100b are always independent of each other. If the positioning pin holes 102 are through holes, that is, the pre-mounting area 100a and post-implementation area 100b Corresponding positioning pin holes 102 If they are connected, the positioning pin holes 102 corresponding to the pre-mounting area 100a and the post-mounting area 100b may be the same. In some examples, in order to reduce the number of open holes in the bonded sheet mounting area 100 and maintain the load-bearing capacity of the bonded sheet mounting area 100, the pre-mounting area 100a and the post-mounting area 100b can be provided to share one positioning pin hole 102. In this case, a positioning pin 202 is inserted from the front of the middle frame 10 into one end of the positioning pin hole 102 facing the front of the middle frame 10, and a positioning pin 202 is inserted from the rear of the middle frame 10 into the other end.

[0017] Continuing to refer to Figures 1 and 2, in some examples, a vertex projection 103 is provided between the pre-mounting region 100a and the vertex of the rectangle corresponding to the vertex region in which it is located. Accordingly, the bonding sheet 20 that engages with the pre-mounting region 100 is provided with a first position limiting groove 203 for the vertex projection 103 to pass through. The first position limiting groove 203 penetrates the bonding sheet 20, and the vertex projection 103 is , thisWhen the bonding sheet 20 engages with the pre-mounting area 100a, it passes through the first position limiting groove 203 of the bonding sheet 20. When the bonding sheet 20 is fitted into the pre-mounting area 100a, the apex projections 103 are engaged with the first position limiting groove 203 so that the bonding sheet 20 is fitted onto the apex projections 203 of the four intermediate frames 10. This pre-fixing between adjacent intermediate frames 10 in a direction parallel to the display surface ensures that at least four intermediate frames 10 do not separate from each other in a direction parallel to the display surface.

[0018] Furthermore, since the display module needs to be attached to the front of the middle frame 10, the pre-implementation area 100a is the middle frame. 10 If the rear side is recessed, a vertex projection 103 is provided between the pre-mounting area 100a and the vertex of the rectangle corresponding to the vertex region where it is located. This avoids the problem that the corner region of the display module attached to the front side of the middle frame 10 is not supported by the middle frame 10 because the entire vertex region of the middle frame 10 is recessed. ru. The provision of the apex projection 103 improves the support capacity of the front display module from the middle frame 10, and improves the flatness of the display surface of the display device or bonded display provided by the middle frame 10.

[0019] In Figure 2, the first position limiting groove 203 of the bonding sheet 20 is located in the middle of the bonding sheet 20 and is surrounded by the body of the bonding sheet 20. However, in some other examples of this embodiment, the bonding sheet 20 may have other structures. For example, in the schematic diagram of another bonding sheet 20 and the first screw fastener 30 shown in Figure 5, the body of the bonding sheet 20 does not form a closed annular shape, and the first position limiting groove 203 is not completely surrounded by the body of the bonding sheet 20. It is understood that the bonding sheet 20 shown in Figure 2 is used to bond four intermediate frames 10, and the bonding sheet 20 shown in Figure 5 is used to bond two intermediate frames 10. In the entire bonded display, Depending on the joining location, different shapes of joining sheets 20 can be selected. As shown in Figures 4 and 5, a joining sheet 20 having two first screw fasteners 30 may be used for the peripheral area of ​​the joined display, while a joining sheet 20 having four first screw fasteners 30, as shown in Figure 2, may be used for other areas of the joined display. .

[0020] Continuing to refer to Figures 2 and 5, in some examples, When joining, The plane in contact between the bonding sheet 20 and the bonding sheet mounting area 100 is the plane of the boss 204 formed on the bonding sheet 20. The bonding sheet 20 includes at least two bosses 204, and the planes of each boss 204 are located at the same horizontal height, and the planes in contact with the planes of the bosses 204 in the same intermediate frame 10 are also located at the same horizontal height. When different intermediate frames 10 are in close contact with the bosses 204 corresponding to the bonding sheet 20, it is possible to ensure that the entirety of these intermediate frames 10 are on the same plane. The bosses 204 are smooth planes, and accordingly, the surfaces of the intermediate frame that are in contact with and connected to the bosses 204 are also smooth planes. The bonding through-hole 201 is provided in the bosses 204. Other than the smooth plane of the bosses 204, other surfaces of the bonding sheet 20 may be relatively rough to reduce manufacturing costs, and accordingly, other surfaces of the intermediate frame, other than the surface in contact with the bosses 204, may be relatively rough to reduce manufacturing costs. In this embodiment, as shown in Figure 3, each post-mounting region 100b on the rear side of the middle frame is provided with a boss 106 corresponding to the boss 204 of the bonding sheet 20. Each boss 106 is located at the same horizontal height and is a smooth plane. Each boss 106 protrudes from the rear side of the middle frame 10 to facilitate polishing and to ensure that each boss 106 is located at the same horizontal height. The engagement between each boss 204 of the bonding sheet 20 and the bosses 106 on the back surface of the different middle frames ensures flatness after multiple middle frames are joined. It is understood that the same bosses as the bosses 106 may also be provided in each post-mounting region 100a on the front side of the middle frame.

[0021] In order to fix a jointed display, which is formed by joining two inner frames 10, to a mounting carrier such as a mounting bracket or a wall, it is necessary to fix the inner frame 10 to the mounting carrier. It is understood that there are two methods for fixing the inner frame 10 to the mounting carrier: one is to directly apply an external fastener to the inner frame 10, thereby fixing the inner frame 10 to the mounting carrier, and the other is to apply an external fastener to the joint sheet 20, which is fixed to the inner frame 10, thereby indirectly achieving the connection and fixing between the inner frame 10 and the mounting carrier through the joint sheet 20. In the former method, fixing holes are usually provided in the inner frame 10, and in the latter method, fixing holes are provided in the joint sheet 20.

[0022] Continuing to refer to Figures 1 to 6-2, in some examples, the installer mounts and joins the intermediate frame 10 from the front side to form a joined display, and this mounting method is sometimes simply called "front mounting." In this case, the installer may not first attach the display module to the front side of the intermediate frame 10, but instead first attach the joining sheet 20 to the front side of the intermediate frame 10, complete the locking of the joining sheet 20 and the intermediate frame 10 together with the first screw fastener 30, and complete the joining of multiple intermediate frames 10. Alternatively, the installer can attach the intermediate frame 10 to the mounting bracket (i.e., mounting carrier) using the second connecting sheet 64 (see Figure 6-2) and the second external fastener 65. Multiple inner frames 10 to be fixed are positioned on the front side of the mounting bracket, and the second connecting sheet 64 is positioned on the rear side of the mounting bracket. Then, one end of the second external fastener 65 is inserted from the front side of the inner frame 10 into an external fixing hole 104 provided in the end corner region of the inner frame 10. After the one end of the second external fastener 65 passes through the external fixing hole 104 (see Figure 4), it is inserted into the second connecting hole in the second connecting sheet 64. Here, the external fixing hole 104 is a through hole (without threads), the second connecting hole is a threaded hole or a through hole, and the second external fastener 65 may be a screw fastener such as a bolt, but is not limited to this. The second external fastener 65 is screwed through the second connecting hole or connected and fixed to the second connecting hole with a nut, thereby fixing the mounting bracket and the inner frame 10. After the locking is complete, the inner frame 10 and the second connecting sheet 64 are attached to the mounting bracket. 63 of in between Sandwich I am After the middle frame 10 is secured, the installer can attach the display module from the front of the middle frame 10 to obtain a bonded display fixed to the mounting bracket. In other examples, the mounting carrier is mounted using a mounting bracket. 63 The wall may be changed to one with load-bearing capacity, in which case the external fixing hole 104 in the middle frame 10 may engage with a third fastener, the third fastener may be a screw fastener such as a tapping screw or an expansion screw, and one end of the third fastener is inserted into the wall through the external fixing hole 104 in the middle frame 10, thereby fixing the middle frame 10 to the wall.

[0023] In some examples, the external fixing holes 104 and the bonding sheet mounting area 100 may be located in the same corner region or distributed in different corner regions. In some examples, the bonding sheet mounting area 100 and the external fixing holes 104 are provided in any of the four corner regions of the middle frame 10. In this case, there is no need to distinguish the arrangement position of the middle frame 10, regardless of whether the middle frame 10 is joined or attached to an external wall or bracket, which is advantageous in improving the operational efficiency of the installer and reducing the operational burden.

[0024] In this embodiment, the installer mounts and joins the middle frame 10 from the rear side to form a joined display, and this mounting method is simply called "post-installation". In this case, the middle frame 10 is not fixed to the mounting bracket by external fixing holes 104, but rather the joining sheet 20 is provided with a third connection hole 205 having female threads, so that the joining sheet 20 joins multiple middle frames 10, while also being fixed to the external first connecting sheet 62 by the third connection hole 205 having female threads, thereby achieving connection between the middle frame 10 and the first connecting sheet 62. Referring to Figures 2 and 6-1, first, the installer may attach the connecting sheet 20 to the rear side of the middle frame 10 and complete the locking of the connecting sheet 20 and the middle frame 10 with the first screw fastener 30. Next, one end of the first external fastener 61 (which may be a screw fastener, but is not limited thereto) is passed from the rear side of the first connecting sheet 62 through the first connecting hole without threads in the through hole in the first connecting sheet 62, and then fastened to the third connecting hole 205 having a female thread in the connecting sheet 20, thereby completing the connection and fixing of the connecting sheet 20 and the first connecting sheet 62. In Figure 6-1, the connecting sheet 20 and the first connecting sheet 62 are located on the front and rear sides of the mounting bracket 63, respectively. In the post-installation configuration, the middle frame 10 does not need to be connected to the first connecting sheet 62, and there is no need to provide a separate hole in the middle frame 10 for connection to the first connecting sheet 62, thus simplifying the structure of the middle frame 10.

[0025] This embodiment further provides a joining assembly including a joining sheet provided in any one of the above examples, wherein the joining assembly further includes a first screw fastener, a first connecting sheet, a first external fastener, a second connecting sheet, and a second external fastener, where the joining sheet is for joining a plurality of intermediate frames, for example, two or four intermediate frames. The first and second connecting sheets are for securing the joined plurality of intermediate frames or a joined display formed after joining to a mounting carrier. When the joined middle frame is fixed to a mounting carrier such as a mounting bracket, one can choose to use either the first connecting sheet or the second connecting sheet. For example, if the "rear mounting" configuration is selected, the first connecting sheet is used, and if the "front mounting" configuration is selected, the second connecting sheet is used. In the "rear mounting" configuration, the first connecting sheet engages with the joining sheet by the first screw fastener, specifically passing through the first sub-connecting sheet and then through the connecting hole in the joining sheet. In the "front mounting" configuration, the second connecting sheet engages with the middle frame, specifically passing through the first screw fastener from the front of the middle frame, through the external fixing hole in the middle frame, and then through the second connecting sheet. The joining sheet according to this embodiment is for joining the inner frame from the front or rear. The joining sheet engages with the positioning pin holes of the inner frame by positioning pins, and the boss surface of the joining sheet is positioned on the same horizontal plane and in close contact with the inner frame, thereby reducing the joining seam and improving the flatness of the joining. At the same time, the inner frame may be used for joining from the front or from the rear, making the installation operation simple and allowing for a wide range of applications.

[0026] This embodiment provides a bonded display comprising at least two bonded frames, at least two display modules, and at least two rear covers, wherein each display module is mounted on the front side of each frame, and each rear cover is mounted on the rear side of each frame.

[0027] The intermediate frames in this embodiment may, but are not limited to, the joining sheets in each of the above examples. The joining display 7 includes a joining sheet 20, at least two first screw fasteners 30, and at least two intermediate frames 10, as shown in Figures 7 and 8. Since the intermediate frames 10 are fixed to the joining sheet 20 by the first screw fasteners 30, the joining sheet 20 is used as a "bridge" to join different intermediate frames 10. A single joining display 7 may include two or more joining sheets 20 that are not exactly the same in structure. For example, in Figure 7, some of the joining sheets 20 in the joining display 7 may be used to join four intermediate frames 10, while other joining sheets 20 may be used to join only two intermediate frames 10, so that one joining sheet 20 corresponds to at least two intermediate frames 10, and simultaneously, one intermediate frame 10 It is understood that this may correspond to at least two bonding sheets 20.

[0028] The bonded display 7 further includes a plurality of display modules 40 attached to the front side of the middle frame 10, as shown in Figure 8. In some examples, the display modules 40 may be removably fixed to the middle frame 10 by means of magnetic attraction, locking, screwing, or even adhesive. For example, referring further to Figures 9 and 13, a first magnetic attraction member 411 is provided on the display module 40, and a second magnetic attraction member 111 is provided on the front side of the middle frame 10, and the first magnetic attraction member 411 and the second magnetic attraction member 111 are positioned opposite each other when the display module 40 is attached to the middle frame 10 and are attracted to each other. One of the first magnetic attraction member 411 and the second magnetic attraction member 111 may be a magnet, the other may contain a ferromagnetic metal such as iron, cobalt, or nickel, or both may be magnets.

[0029] In some examples, the second magnetic attraction member 111 is connected to the connecting rod 1111 and magnetic chuck 1112Referring to the second magnetic attraction member 111 shown in Figure 10 or Figure 12, functionally, the second magnetic attraction member 111 comprises a magnetic attraction front end 111a and a fixed rear end 111b, the magnetic attraction front end 111a and the fixed rear end 111b are located at both ends of the connecting rod 1111, and referring to Figure 11, the inner frame 10 is provided with a magnetic attraction member fixing hole 1110, the fixed rear end 111b is inserted into the magnetic attraction member fixing hole 1110, while the magnetic attraction front end 111a is exposed on the front side of the outer frame 10 in order to engage with the first magnetic attraction member 411 in the display module (see Figures 9 and 13). Here, the height to which the connecting rod 1111 is exposed on the front side of the inner frame 10 is called the exposure height, and in this embodiment, the exposure height is adjustable, that is, the distance between the magnetic attraction front end 111a and the inner frame 10 on the connecting rod 1111 is adjustable, thereby the magnetic attraction front end 111a The distance between the connected display module 40 and the middle frame 10 can be adjusted, and with this installation, the middle frame 10 can be joined to form a joined display. 7 After forming, the bonded display 7 The distance between each display module 40 and the central frame 10 can be flexibly adjusted, thereby ensuring that the display surfaces of each display module are on the same plane, and the bonded display 7 This can improve the overall display effect.

[0030] In this embodiment, the magnetic attraction front end 111a includes a front operating section designed to be engageable with an external tool (e.g., a screwdriver, sleeve, etc.), thereby allowing the front side of the middle frame 10 to adjust the exposed height of the connecting rod 1111. Therefore, if it is necessary to adjust the distance between a display module and the middle frame 10, the installer may first remove the display module 40, then operate the front operating section with an external tool, and after the adjustment is complete, reattach the display module 40 to the middle frame 10. In some examples, the fixed rear end 111b is exposed at least in part to the rear side of the outer frame 10, and the fixed rear end 111b also includes an operating section for adjusting the exposed height of the connecting rod 1111, and is referred to as the "rear operating section" in correspondence with the front operating section. Furthermore, if the installer attempts to adjust the exposed height of the connecting rod 1111 using the rear operation unit, it must be operated from the rear side of the middle frame 10. In this case, the installer can choose to adjust the height without removing the display module 40, which is convenient for the installer to identify the difference between the display surface of this display module 40 and the display surface of other display modules 40 in real time. The exposed height of the connecting rod 1111 in the second magnetic attraction member 111 is supported by adjustment from both the front and rear sides of the middle frame 10, making it convenient for the installer to flexibly select the adjustment method according to the application scene to improve the flatness of the display surface.

[0031] In some examples, the connecting rod 1111 and the magnetic attraction member fixing hole 1110 are screwed together, with male threads on the surface of the connecting rod 1111 and female threads on the inner wall of the magnetic attraction member fixing hole 1110, and the threads of both are compatible with each other, so that the connecting rod 1111 can move along its axial direction through the magnetic attraction member fixing hole 1110 by rotation. In some examples, the front operating part may be a recessed pattern provided on the magnetic attraction front end 111a, and / or the rear operating part is fixed rearThe recessed pattern may be provided on the end 111b, and the recessed pattern may include, but is not limited to, non-circular patterns such as a roughly "one" shape, a roughly "cross" shape, or a roughly "*" shape, a pentagonal pattern, or a hexagonal pattern. Accordingly, the external tool should be provided with an end that can be inserted into and conforms to such a recessed pattern, for example, the external tool may be a screwdriver. In some other examples of this embodiment, the front operating part may be a non-circular contour on the end face of the magnetic attraction front end 111a, and / or the rear operating part may be a non-circular contour on the end face of the fixed rear end 111b, where non-circular contour refers to non-circular shapes such as triangles, rectangles, parallelograms, regular hexagons, and regular octagons, and accordingly, the external tool should have a recessed hole of a shape and size that can engage with such an end face, for example, the external tool may be a sleeve.

[0032] In some examples, the second magnetic attraction member 111 shown in Figure 12 may further have a magnetic chuck 1112 in addition to the connecting rod 1111, and the magnetic chuck 1112 is fixed to the end of the connecting rod 1111 that is close to the magnetic attraction front end 111a and can be attracted to the first magnetic attraction member 411. In this case, the magnetic attraction front end 111a is actually the end where the magnetic chuck 1112 is located, and the magnetic attraction function of the magnetic attraction front end 111a is realized by the magnetic chuck 1112. In some examples, the magnetic chuck 1112 may be a magnet, and since the area of ​​the outer contour of the magnetic chuck 1112 is larger than the end face of the connecting rod 1111 that is close to the magnetic attraction front end 111a, the magnetic chuck 1112 and the first magnetic attraction member 411 Through magnetic attraction engagement, the magnetic attraction front end 111a of the connecting rod 1111 and the first magnetic attraction member are engaged. 411 Compared to the case of direct use of magnetic attraction engagement between the second magnetic attraction member 111 and the first magnetic attraction member 411 This increases the area between them that faces each other, improving the mutual attractive force between them, and the display module 40 Center frame 10 This can improve the reliability of the fixation to the target.

[0033] In some examples, the end face of the magnetic chuck 1112 away from the connecting rod 1111 may be provided with a recessed pattern to form a front operating section, which may include, but is not limited to, a roughly "straight" shaped pattern. These recessed patterns make it easier for the installer to rotate the magnetic chuck 1112 using a screwdriver or other attachment / detachment tool, and further drive the connecting rod 1111 to move along its axis as the magnetic chuck 1112 rotates. In other examples of this embodiment, the outer contour of the magnetic chuck 1112 may be a shape other than a circle, such as a regular hexagon, making it easier for the installer to adjust the distance between the magnetic chuck 1112 and the surface of the inner frame 10 using an external tool such as a sleeve. In one example of this embodiment, as shown in Figure 12, the magnetic attraction front end of the second magnetic attraction member 111 111a A magnetic chuck with a regular hexagonal outer contour is provided, forming a front operating section, and a fixed rear end 111b The end face is provided with a recessed pattern that can be operated by a screwdriver, and this recessed pattern forms a rear operating section. In another example, both ends of the connecting rod 1111 of the second magnetic attraction member 111 are provided with magnetic chucks 1112, each having a non-circular outer contour, and the end face of the magnetic chuck 1112 away from the connecting rod 1111 is further provided with a recessed pattern.

[0034] In some examples, the display module 40 The inner frame is constructed with a hole-pin structure. 10It can be engaged with, for example, continuing to refer to Figures 9 and 13, a second hole-pin connector 112 is provided on the front side of the middle frame 10 and a first hole-pin connector 412 is provided on the rear side of the display module 40. In the example corresponding to Figure 9, the second hole-pin connector 112 may be a pin, but the first hole-pin connector 412 may be a pinhole, and it is understood that in some other examples of this embodiment, the specific embodiments of the first hole-pin connector 412 and the second hole-pin connector 112 may be interchangeable. However, as shown in Figure 9, by providing a pin on the middle frame 10 and only a pinhole on the display module 40, the flatness of the surface of the display module 40 can be ensured, and the packaging and transport of the display module 40 can be facilitated.

[0035] In some examples, as shown in Figure 13, a fixing ring 413 is further provided on the back of the display module 40, and a fixing rope (not shown) that engages with the fixing ring 413 is tied to the fixing ring 413, while the middle frame 10 This connects to, and as a result, bonded display 7 The environment in which they are located is affected by earthquakes, typhoons, etc. Disaster Even if harm occurs, the display module 40 will remain within the middle frame. 10 It will not easily detach (fall) from the display module 40, preventing damage from falling and more reliably preventing injury to people if the display module 40 falls, thus protecting property and personal safety.

[0036] Bonded display according to this embodiment 7 Each display module 40 in the middle frame is attracted by magnetic force. 10 It is provided in such a way that attachment and detachment are made easy, and the joint display 7 Reduces the burden of attaching and detaching, and connects to the display. 7 This is advantageous for improving the installation efficiency of the middle frame. 10 Display module in 40 A second magnetic attraction member that engages with 111 Connecting rod 1111 Because the exposure height can be adjusted, the middle frame 10 After the connection is complete, each display module40 The display surfaces can be ensured to be on the same plane, thereby improving the display effect. In this embodiment, the second magnetic attraction member 111 Connecting rod 1111 The exposure height is the middle frame 10 Adjustments from the front are also supported, and the middle frame 10 Rear-side adjustments are also supported, allowing the installer to connect the display. 7 Depending on the application scenario, the adjustment method can be flexibly selected to improve the flatness of the display surface.

[0037] In this embodiment, the central frame and its corresponding display module may constitute a single display device or display means having a display function; therefore, the bonded display in the above embodiment may be considered to be formed by joining multiple display devices. In this embodiment, for ease of understanding, the display devices 8 This will be explained from this point of view. In this embodiment, the display device 8 The middle frame 10 and display module 40 and usually one inner frame 10 two display modules 40 It corresponds to one inner frame 10 Fewer or more display modules 40 This does not exclude cases where a display device is installed. In some cases, 8 This further includes a rear cover. As shown in Figure 14, in the schematic diagram of the divided display device 8, the rear cover 50 is attached to the rear side of the middle frame 10, and the display module of the display device 8 is accessible from the rear side of the middle frame 10. 40 This supports the following. In this embodiment, the support module is the display module. 40 This refers to a module that provides the necessary support for the display, and the support display module includes, but is not limited to, a power supply and a signal relay board, and the rear cover. 50 This may shield the back of the display module 40, improving the appearance of the display device 8, while also serving a function such as moisture protection and dust protection.

[0038] In some examples, the rear cover 50 may be fixed to the inner frame 10 by screwing, fastening, or even adhesive. In some other examples of this embodiment, the rear cover 50 may engage with the inner frame 10 by magnetic attraction, similar to the display module 40. For example, referring further to Figure 15, the inner frame 10 is provided with a fourth magnetic attraction member 114, and the rear cover 50 is provided with a third magnetic attraction member 511 that engages with the fourth magnetic attraction member 114. The third magnetic attraction member 511 and the fourth magnetic attraction member 114 are positioned opposite each other when the rear cover 50 is attached to the inner frame 10, and they attract each other. It is understood that one of the third magnetic attraction member 511 and the fourth magnetic attraction member 114 may be a magnet, the other may contain a ferromagnetic metal, or both may be magnets.

[0039] In some examples, the mounting of the rear cover 50 to the intermediate frame 10 does not affect the rear post-mounting area 100b of the intermediate frame 10. The intermediate frame 10 includes a rear cover shielding area, which is the area of ​​the intermediate frame 10 that is shielded by the rear cover after the rear cover 50 is mounted to the intermediate frame 10. In this embodiment, the rear cover shielding area is the intermediate frame 10 It does not overlap with the bonded sheet mounting area. In the example corresponding to Figure 6-1 or Figure 15, the rear cover 50 is fitted into the middle frame 10 and can cover the area surrounded by the side beams of the middle frame 10. The four corners of the rear cover 50 are provided with corresponding notches. When the rear cover 50 is installed, it does not obstruct the post-installation area 100b, so the bonding sheet is installed in the post-installation area 100b. 20 When multiple inner frames 10 (or display devices 8) are joined together, the joining sheet 20 This does not interfere with the attachment of the rear cover 50 to the inner frame 10.

[0040] In some cases, a protruding locking tab is attached to one side of the rear cover 50. 512A locking tongue 512 is provided on the bottom edge of the rear cover 50, as shown in Figure 15, and a locking tongue groove 1151 for accommodating the locking tongue 512 is also provided on the corresponding bottom side beam of the middle frame 10. The locking tongue groove 1151 extends away from the rear cover 50, and a shielding portion 1152 is provided in a portion of the area above the groove opening of the locking tongue groove 1151. The shielding portion 1152 protrudes to the side beam so as to provide a accommodating space above the locking tongue groove 1151, into which the locking tongue 512 is inserted below the shielding portion 1152 in a direction parallel to the groove opening, and the portion of the groove opening not covered by the shielding portion 1152 is inserted into the locking tongue groove 1151. The locking tongue 512 can be inserted into the housing space from a direction substantially parallel to the groove opening of the locking tongue groove 1151, and the internal space of the locking tongue groove 1151 can rotate with the rear cover 50 from a state parallel to the groove opening to a state perpendicular to the groove opening, that is, the internal space of the locking tongue groove 1151 can be used when the rear cover 50 loads the locking tongue 512 into the display device 8 It can be rotated from a direction perpendicular to the display surface to a direction parallel to the display surface.

[0041] When the rear cover 50 is mounted on the inner frame 10 by the third magnetic attraction member 511 and the locking tongue 512, the rear cover 50 is detachable from the rear side of the inner frame 10, making the attachment and detachment operation simple and easy to achieve. Furthermore, the rear cover 50 does not need to be provided with screw holes or the like for engaging with the inner frame 10, which is advantageous in improving the processing efficiency and integrity of the rear cover 50. At the same time, when the rear cover 50 is installed, the rear cover 50 is positioned perpendicular to the display surface, the locking tongue 512 is inserted into the locking tongue groove 1151, and the rear cover 50 is quickly positioned on the middle frame 10. Subsequently, by rotating the rear cover 50 to a direction parallel to the display surface, the third magnetic attraction member 511 on the rear cover 50 is accurately attracted to the fourth magnetic attraction member 114 on the middle frame 10, enabling quick installation of the rear cover. This avoids the need to manually align the third magnetic attraction member 511 and the fourth magnetic attraction member 114 when installing the rear cover 50, thereby improving the installation efficiency of the rear cover 50. On the other hand, after the locking tongue 512 is inserted into the locking tongue groove 1151, the side beams, locking tongue groove 1151, and shielding portion 1152 of the middle frame 10 also support the rear cover 10 to some extent, limiting its position, thereby improving the reliability of the connection between the rear cover 50 and the middle frame 10.

[0042] In some examples, the inner frame 10 is provided with a cutout area 113 large enough for the display module 40 to pass through on both the front and back sides. For example, if the cutout area 113 is rectangular, at least the size of the diagonal of the rectangle is larger than the size of the shorter side of the display surface of the display module 40. In some examples, if the cutout area 113 is rectangular, the size of the longer side of the cutout area 113 is also larger than the size of the shorter side of the display surface of the display module 40. However, as a person skilled in the art will understand, since structures such as bonded sheet mounting areas are provided in the vertex corner areas of the inner frame 10, the cutout area 113 is usually not a perfect rectangle. In this case, the length of the line connecting at least two points in the contour of the cutout area 113 is larger than the size of the shorter side of the display surface of the display module 40. The size of the cutout area 113 is such that the display module 40 can pass through on both the front and back sides of the inner frame 10. Therefore, after the front display module 40 of the inner frame 10 is removed, the display module 40 may reach the rear side of the inner frame 10 through the cutout area 113.

[0043] In some examples, the central frame 10 has a single hollow region 113 formed by being surrounded only by four side beams, but in some other examples of this embodiment, the central frame 10 has at least one intermediate beam in addition to the four side beams 12 This further includes the following. As shown in Figure 1, the four side beams 11 are at least endless, and the outline of the vertical projection on the display surface is approximately rectangular. Since both ends of one intermediate beam 12 are connected to two opposing side beams 11, the intermediate beam 12 is divided into two hollow regions 113 within the area enclosed by the side beams 11. 10 Intermediate beam in 12 If there is more than one, then there are two or more hollow areas. 113 The intermediate beam may be partitioned. In some examples, each intermediate beam 12 These are arranged parallel to each other, and in some examples, each intermediate beam 12 There may be some that are partially perpendicular to each other, and in some examples, each intermediate beam 12 There may be elements that are partially perpendicular to each other, and the middle frame 10Inside are two mutually perpendicular intermediate beams 12 Includes intermediate beam 12 It forms a "cross" and has a central frame. 10 There are four hollow areas inside. 113 It includes.

[0044] In this embodiment, the display module 40 The middle frame 10 Attachment and detachment from the front is also supported, and the middle frame 10 The display module can also be attached and detached from the rear. 40 Referring to Figures 14 and 15, when the display module 40 is attached to the inner frame 10 by magnetic attraction, the installer can then remove the display module from the front using a tool such as a chuck. 40 The installer can detach the display module 40 from the inner frame 10 by first removing the rear cover 50 from the rear of the inner frame 10, and then applying a pressing force to the display module 40 from the rear of the inner frame 10. At the same time, the display module 40 does not escape the installer's control and remains held by the installer or connected to a detachment tool controlled by the installer. Subsequently, the installer, who is at the rear of the inner frame 10, can achieve the effect of completing the removal of the display module 40 from the rear of the inner frame 10 through the cutout area 113 in the inner frame 10 by rotating the orientation of the display module 40 and moving the display module 40.

[0045] In some examples, a module gripping portion may be provided on the rear side of the display module 40 to facilitate removal of the display module 40 from the rear side of the inner frame 10. Referring to the schematic structural diagrams of the display module 40 shown in Figures 13 and 16, a handle is provided on the rear side of the display module 40 as a module gripping portion 414, allowing the installer to remove the inner frame 10When attaching or detaching the display module 40 from the rear, the module gripping portion 414 can be used to operate it, making it easier for the installer to operate and improving safety in the process of removing or attaching the display module 40 compared to cases where the module gripping portion 414 is not provided.

[0046] As shown in Figure 16, the display device 8 In this configuration, the display support module 60 is mounted on the middle frame 10 and located on the rear side of the middle frame 10. In some examples, the display support module 60 is mounted on the side beams of the middle frame 10, and in some other examples, the display support module 60 is mounted on the middle beams of the middle frame 10. 12 It is attached to the middle frame 10. In some examples, the display support module 60 is supported for attachment and detachment from both the front and rear sides of the middle frame 10. Therefore, in some examples, the display support module 60 is fixed to the middle frame 10 using a double operating end fixture. The double operating end fixture, as its name suggests, has two operating ends, each located on the front and rear sides of the middle frame 10, and both operating ends may be used to attach and detach the display support module 60. For example, the double operating end fixture may be a stud or stud bolt, both of which have recessed patterns on their end faces. In some examples, the double operating end fixture for fixing the display support module 60 may be a stud pin.

[0047] The following is the display module. 40 To briefly describe the other structures, referring to Figure 17, the display module 40 includes a lamp panel 401 and a bottom case 402. The lamp panel 401 is provided with a chip array consisting of multiple light-emitting chips, such as an LED array, a Micro-LED (micro light-emitting diode) array, a Mini-LED (mini light-emitting diode) array, and an OLED (organic light-emitting semiconductor) array. The lamp panel 401 is fixed to the front side of the bottom case 402, and the display module 40 is in the middle frame. 10 When installed, the rear of the bottom case 402 becomes the middle frame10 It faces the rear.

[0048] Furthermore, since the operation of the display module 40 requires current drive and also requires the reception of display control signals, the middle frame 10 Since it is necessary to electrically connect to the display support module 60 provided therein and connect to the signal, the display module 40 is provided with a power interface corresponding to the power supply and a signal interface corresponding to the signal adapter board. For the display module 40, all of these interfaces belong to the external interfaces of the display module 40, and the middle frame 10 It is used to connect to the module interface in the display module. In some examples, the display module 40 further includes a distribution board 403, as shown in Figure 17, the distribution board 403 is located on the rear side of the bottom case 402, i.e., on the side of the bottom case 402 facing the lamp panel 40. The external interface of the display module 40 is provided on the distribution board 403. In some examples, the distribution board 403 is provided with only one set of external interfaces, including various externally connected interfaces that the display module 40 needs to operate. In other examples of this embodiment, the distribution board 403 It may also include two sets of external interfaces, as shown in Figure 13, in the display module 40 shown in Figure 13, external interfaces 4030, which are the left interface and the right interface, are provided on both the left and right sides of the distribution board 403, and one display module 40 is a central frame 10 In addition to supporting mounting on the left side, the middle frame 10 It also supports mounting on the right side, eliminating the need for installers to distinguish the mounting position of the display module 40 when installing it on-site, thereby increasing the versatility of the display module 40 and improving the installation efficiency of the display module 40.

[0049] Display device according to this embodiment 8 In the display support module 60Double backup is provided to at least one of the power and signal adapter boards in the system, for example, one display device 8 This includes one main power supply and at least one backup power supply, one main signal adapter board and at least one backup signal adapter board. (Display device) 8 Display support module in 60 If there is a backup, one of the display support modules 60 If it malfunctions, the display device 8 The display support module is backed up accordingly. 60 Switched to and continued operating, display device 8 It may continue to display on the display device. 8 If applied to a conference room, the installer will be responsible for the display equipment. 8 A faulty display support module is located at the rear. 60 This allows for maintenance, and in this way, maintenance work does not affect the order and image of the conference room, nor does it affect the continuation of the meeting, thus contributing to an improved user experience. Referring to Figures 17 and 13, since a large number of light-emitting chips are provided on the front side of the lamp panel 401 and a large number of drive chips are provided on the rear side of the lamp panel 401, when the lamp panel 401 is operated by electric current, a large amount of heat is generated, and heat dissipation must be considered to avoid the impact on the performance of the light-emitting chips and drive chips due to the high-temperature environment. In some examples, a heat conductive material is provided between the lamp panel 401 and the bottom case 402, and the heat conductive material guides the heat from the lamp panel 401 to the bottom case 402 side, allowing it to be released from the bottom case 402. Furthermore, in some examples, a plurality of heat dissipation fins 4020 are provided on the surface of the bottom case 402 away from the lamp panel 401, and the heat dissipation fins 4020 increase the surface area of ​​the bottom case 402, which is advantageous in improving the heat dissipation efficiency of the bottom case 402.

[0050] In this disclosure, in order to ensure the heat dissipation efficiency of the bottom case 402, the surface of the wiring plate 403 located on the side of the bottom case 402 away from the lamp panel 401 is usually made small, and thus the wiring plate 40 3 This avoids the heat dissipation fins 4020 from being obscured. Furthermore, in order to ensure that the module gripping portion 414 provided on the bottom case 402 can be exposed to the wiring plate 403, in this disclosure the central portion of the wiring plate 403 is perforated, and the module gripping portion 414 is perforated through the central portion and can extend from the wiring plate 403.

[0051] In the display device according to this disclosure, the display module is detachable from both the front and rear sides of the inner frame, the rear cover is detachable from the rear side of the inner frame, and the display support module is also fixed to the inner frame using a double operating end fixing device, so the display support module is also detachable from both the front and rear sides of the inner frame. This makes it convenient for installers to maintain each component of the display device in different scenarios, improving the flexibility and efficiency of maintenance of the display device and reducing the maintenance workload. Furthermore, since two sets of external interfaces may be provided on the distribution plate of the display module, the versatility of the display module is increased and the installation efficiency of the display module is improved. At the same time, a heat conductive material may be provided between the lamp panel and the bottom case of the display module, and heat dissipation fins may be provided on the rear side of the bottom case. By installing these, the heat dissipation capacity of the display module to the outside is improved and the quality of the display module is improved.

[0052] Continuing to refer to Figure 14, the display device 8 is primarily supported by the middle frame 10, while the display module 40 and rear cover 50 do not require much load. Therefore, when the display device 8 needs to be transported, the middle frame 10 is usually used as the load-bearing body. In some examples, the middle frame 10 is provided with a lifting handle to facilitate transport. Figure 1 5 and figure 16 The middle frame 10This is a schematic diagram of a partial structure, where the lifting handle 105 is located on the rear side of the middle frame 10 and positioned for a person to grip. In some examples, the lifting handle 105 is positioned on the middle frame 1 so that the installer can maintain as upright a posture as possible when applying force to lift the middle frame 10. 0 It may also be provided on the upper rear side. In some examples, the lifting handle 105 is provided in an area where the rear of the middle frame 10 is shielded by the rear cover 50, thereby ensuring the external appearance of the display device 8. However, at the same time, it is necessary to remove the shielding of the lifting handle 105 by the rear cover 50 when transporting the display device 8, and in some cases, it may be chosen to remove the rear cover 50 before transporting the display device 8 and then attach the rear cover to the middle frame 10 after transporting it to its destination.

[0053] In some examples, a handle window is provided in the rear cover 50 of the display device 8 at a location corresponding to the lift handle 105, thereby ensuring that the installer can access the lift handle 105 located on the inner frame 10 without removing the rear cover 50. However, the opening of the handle window in the rear cover 50 affects the integrity of the rear cover 50 and reduces its ability to protect the inside of the display device 8 from moisture and dust. Referring to Figures 18 and 19, in other examples of this embodiment, the rear cover 50 includes a rear cover body 501 and a window stopper 502, and the lift handle is located in the rear cover body 501. 105 Since a handle window 5010 is provided in the opposite location, the installer can put their hand through the handle window 5010 and then pull up the handle. 105 It can be grasped. The handle window 5010 may be rectangular, trapezoidal, or inverted trapezoidal, etc. In Figures 18 and 19, the handle window 5010 is inverted trapezoidal. The window stopper 502 is movablely connected to the rear cover body 501 via a connector, and the window stopper 502 may shield the handle window 5010 in a first state, or expose at least a portion of the handle window 5010 in a second state. Display device having such a rear cover 50 8In contrast, if there is a need for transport, the window stopper 502 can be moved to the second state without removing the rear cover 50, thereby providing a lifting handle. 105 As if gripping Through the handle window 5010 display equipment 8 It is possible to reach inside directly from the outside. When there is no need for transport, the window stopper 502 is a handle window. 5010 Shielding the display device 8 The internal modules may be protected.

[0054] In some examples, the window stopper 502 may be connected to the rear cover body 501 by a snap fit, magnetic attraction, or the like. In this embodiment, the window stopper 502 and the rear cover body 501 may be connected via a rotary connector, as shown in Figure 20, which is a partially enlarged schematic diagram of area Q in Figure 19. The rotary connector 503 is the display module of the rear cover 50. 40 The rotating connector 503 is located on the side facing the rear cover 50, that is, inside the rear cover 50. The rotating connector 503 comprises a first connecting end 5031, a second connecting end 5032, and a rotating shaft 5033. Both the first connecting end 5031 and the second connecting end 5032 are connected to the rotating shaft 5033, and the first connecting end 5031 and the second connecting end 5032 are fixed to the window stopper 502 and the rear cover body 501, respectively. In this embodiment, the first connecting end 5031 may be rotatably connected to the rotating shaft 5033, so the window stopper 502 fixed to the first connecting end 5031 is rotatable with respect to the rotating shaft 5033. The rear cover body 501 is the middle frame 10 After being attached to the rear, the installer lifts it up using the handle. 105 If it is necessary to use the window stopper 502, the window stopper 502 can be rotated relative to the rear cover body 501 by pressing the window stopper 502 so that at least a portion of the handle window 5010 in the rear cover body 501 that is shielding it is exposed. 105 If there is no need to use it, the window stopper 502 can be returned to a state where it is flush with the rear cover body 501.

[0055] Since one end of the rotating connector 503 is connected to the window stopper 502 and the other end is connected to the rear cover body 501, the rotating shaft 5033 of the rotating connector 503 should be located near the side edge of the handle window 5010, and it goes without saying that the axial direction of the rotating shaft 5033 runs along the side edge in which it is located. In some examples, the axial direction of the rotating shaft 5033 is parallel to the upper and lower edges of the handle window 5010, and in some further examples, the axial direction of the rotating shaft 5033 may be parallel to the left and right edges of the handle window 5010. Typically, the upper and lower edges of the handle window 5010 are parallel to the upper and lower edges of the rear cover 50, and simultaneously the pull-up handle 105 Also, because the upper and lower edges of the rear cover 50 are parallel, the person carrying it can insert their four fingers into the inside of the rear cover 50 with their palm facing upwards, pull it up, and smoothly grip the handle, displaying the device 8 This is convenient for performing lifting operations.

[0056] Furthermore, if the rotating shaft 5033 is located above the handle window 5010 and is provided along the upper edge of the handle window 5010, the window stopper 502 will naturally block the handle window 5010 due to the effect of gravity, even when no external force is acting on it. In this case, if the installer needs to use the handle window 5010, they can move the window stopper 502 to the middle frame by waving their hand over it. 10 The handle window 5010 can be opened simply by pushing it inward, and once the installer's hand is out, the external force is removed, so the window stopper 502 Cover the handle window 5010 It will automatically recover.

[0057] In some examples, the rotating connector 503 is a spring hinge, with one of the two hinges of the spring hinge being the first connecting end 5031 and the other being the second connecting end 5032, and the spring hinge includes a return spring that automatically returns the two hinges when no external force is acting on them. In this case, automatic return of the window stopper 502 can be achieved regardless of which side of the handle window 5010 the pivot shaft 5033 is located on. In some examples, the pivot shaft 5033 is located on the lower side of the handle window 5010 and is provided along the lower side of the handle window 5010, in which case when the installer pushes the window stopper 502 by hand, the window stopper 502 rotates downward toward the inside. Referring to Figure 20, in some examples of this embodiment, the window stopper 502 consists of a window stopper body and an inner frame 10 The window stopper body includes a connecting wedge 5020 provided on one side, the window stopper body being the main body of the window stopper 502 and being substantially sheet-like, the connecting wedge 5020 protruding from the surface of the window stopper body and being generally wedge-shaped, the height of which the protrusion increases as the distance from the rotating shaft 5033 increases. In other words, the greater the distance from the rotating shaft 5033 to the connecting wedge 5020, the greater the height of the protrusion from the surface of the window stopper 502. A screw hole is provided in the connecting wedge 5020, and the first connecting end 5031 of the rotating connector 503 is fixed to the connecting wedge 5020 by a screw, the screw being screwed through the connecting hole of the first connecting end 5031 and then into the screw hole of the connecting wedge 5020. In some examples, when the window stopper 502 is in the first state, the plane on which the window stopper 502 exists and the plane on which the rear cover body 501 exists overlap. Here, "overlap" means that the plane on which the rear cover body 501 exists and the plane on which the window stopper 502 exists substantially overlap, but do not absolutely overlap. At the same time, when the window stopper 502 obstructs the handle window 5010, the spring hinge becomes partially open, i.e., half-open, and a certain biasing force is applied to the window stopper 50, and the window stopper 50 2 To avoid loosening, window stopper 50 2 To further ensure its integrity.

[0058] On the other hand, the height of the projection of the connecting wedge 5020 can provide sufficient space for a screw to lock the first connecting end 5031, and in some examples the screw hole provided in the connecting wedge 5020 is a blind hole, and the height of the projection of the connecting wedge 5020 can provide sufficient length for the screw to engage with the screw, thereby achieving locking to the screw. When the screw hole is a blind hole, the screw is in the middle frame of the window retainer 502 10 It does not pass through to the side facing away from it, that is, the rear cover 50 From the outside, the screws connected to the window retainer 502 are not visible, so the rear cover 50 This can improve the appearance. In some examples, the inner frame of the rear cover 50. 10 The thickness in the region near the apex can be thinner than the thickness in other regions. stomach. Referring to Figure 19, in this embodiment, such a relatively thin area in the rear cover 50 is called a "thin edge region" 5011. In Figure 19, two thin edge regions 5011 are provided in the rear cover 50, but in some other examples of this embodiment, the thin edge region 5011 is in the middle frame of the rear cover 50. 10 It may be distributed to all areas near the apex angle region, and in this case, it will be obvious to those skilled in the art that four thin edge regions 5011 may be provided on one rear cover 50. Because the thin edge regions 5011 are thinner than the other regions, these thin edge regions 5011 are easily damaged by external forces, and the installation worker may damage the middle frame 10 If it is necessary to have a hole in the rear cover 50 to allow the internal signal lines or power lines to be routed out from the rear cover 50, the thin edge region 5011 may be directly removed by cutting or the like, or a hole may be formed in the rear cover 50. Display device according to this embodiment 8 The middle frame 10 Pull-up handle 105 A rear cover is provided. 50 It has a pull-up handle. 105 A handle window facing the opposite 5010 By providing this, the display device 8 If it needs to be transported, the installer's hands remain on the rear cover. 50The pull-up handle 105 can be grasped through it. More importantly, the handle window 5010 A window stopper 502 is further provided, and the window stopper 502 In the first state, the handle window 5010 By shielding it, the rear cover 50 To improve the overall appearance and the rear cover 50 Display devices 8 This ensures protection for internal components. (Second state) 5010 At least a portion of the rear cover can be exposed. 50 window handle 5010 By providing this, the installation worker can cover the rear cover 50 It can be attached and removed, and the handle window 5010 If not, the installer will need to attach and detach it, especially the rear cover. 50 When removing the rear cover, 50 Finding the right point of force becomes difficult, increasing the difficulty of operation, but the handle window 5010 If a handle is provided, the installer should place their fingers on the window handle. 5010 By placing it inside, the attachment and detachment process can be completed, improving the convenience of operation.

[0059] Example 2 Since a bonded display includes at least two display modules, the inner frames of each display module need to be electrically connected to facilitate coordinated control between them. The conventional method involves providing through-holes in the adjacent side walls of each inner frame and connecting the circuits of each display module using flexible power connectors through these through-holes. However, flexible power connectors lack a fixed position and are prone to movement. It makes the installation process difficult for the installer. The installer works within the narrow space of the inner frame. 、 It is necessary to operate the electrical interfaces of the two inner frames with both hands, which is inconvenient to operate, the lines become complicated, and power line couplings are prone to colliding with the internal circuitry, causing circuit failure. This disclosure addresses this problem by providing a first electrical interface module and a second electrical interface between two adjacently joined inner frame bodies. moduleThe present invention further provides a bonded display equipped with the following. The first electrical interface module includes a slidable first electrical interface, the positions of the first and second electrical interfaces are fixed, and the first and second electrical interfaces are brought into contact and separated by the linear sliding of a movable device, eliminating the need for installers to insert and remove cables in the narrow space on the side of the inner frame, avoiding the problem of power line connectors easily colliding with the internal circuit and causing circuit failure, making it easy and convenient to operate, the circuit neat and aesthetically pleasing, and the reliability of the interface connection good. The structure of the inner frame, bonding sheet, etc. used in the bonded display in this embodiment may be the structure shown in Embodiment 1 above, or other structures may be used, that is, the bonded display according to this embodiment can be implemented independently of Embodiment 1 above, and for ease of understanding, it will be described below illustratively with reference to the drawings.

[0060] As shown in Figures 21 and 22, this embodiment provides a bonded display formed by joining four display devices 8. In other examples, the user can decide how many display devices 8 are needed depending on the screen size to be displayed, but the bonded display requires at least two display devices 8 to be joined. Referring to Figures 21 to 24, the bonded display according to this embodiment includes at least two interconnected intermediate frames. In this embodiment, the intermediate frames are understood to be relative, with the first intermediate frame 110 and the second intermediate frame 120 being examples. A display module 40 is attached to the front of each intermediate frame (first intermediate frame 110, second intermediate frame 120), and a rear cover 50 (also called a back plate in this embodiment) is attached to the rear. Each intermediate frame (first intermediate frame 110, second intermediate frame 120) includes a side beam 11 (also called a side plate in this embodiment), and the sides of the side beam 11 and the rear cover 50 are fusible to fasten. As shown in Figures 25 to 27, adjacent side beams 11 between the first middle frame 110 and the second middle frame 120 are provided with a first electrical through-hole 151 and a second electrical through-hole 152, respectively, whose positions correspond to each other. After the alignment and joining of the first middle frame 110 and the second middle frame 120 is completed, the first electrical through-hole 151 and the second electrical through-hole 152 can communicate with each other.A first electrical interface module 160 is provided on a rear cover 50 attached to a first intermediate frame 110, and the first electrical interface module 160 includes a bracket 161 and a first electrical interface 162, the bracket 161 includes a fastener 1611 and a movable part 1612 that is movably connected to the fastener 1611, the fastener 1611 is fixed to the rear cover 50, and the movable part 1612 is limited to sliding relative to the fastener 1611 in a first direction, the movable part 1612 is also located on the rear side of the rear cover 50, and the first electrical interface The surface 162 is connected to the movable part 1612 via a second fastener, and the second middle frame 120 is provided with a second electrical interface 171 opposite to the first electrical interface 162, the second electrical interface 171 is fixed to the second middle frame 120 and exposed to the outside through a second electrical through-hole 152, and the first electrical interface 162 slides in the first direction via the movable part 1612 because it is connected to or separated from the second electrical interface 171 via the first electrical through-hole 151. When it is necessary to bring the two inner frames into contact or separate them, the operator can directly or indirectly drive the movable part 1612 located on the back surface of the rear cover 50 to slide the first electrical interface 162 toward the second electrical interface 171 along the first direction (sliding in the forward direction, the direction indicated by the arrow in Figure 29) to bring it into contact with the second electrical interface 171, or slide the first electrical interface 162 toward the second electrical interface 171 (sliding in the reverse direction, i.e., the opposite direction to the forward sliding described above) to detach it from the second electrical interface 171. The first electrical interface 162 and the second electrical interface 171 are brought into contact and separated by the linear sliding of the movable part 1612, eliminating the need for the installer to insert and remove cables in the narrow space on the side of the inner frame, avoiding the problem of power line connectors easily colliding with the internal circuit and causing circuit failure, making operation simple and convenient, the circuit neat and aesthetically pleasing, and ensuring reliable interface connections.

[0061] Referring to the state diagram in Figure 27 where the first electrical interface 162 is not connected to the second electrical interface 171 (i.e., the first electrical interface 162 is separated from the second electrical interface 171), and the state diagram in Figure 29 where the first electrical interface 162 is connected to the second electrical interface 171, the first electrical interface 162 can extend into the second electrical interface 171 of the second intermediate frame 120 (not shown in Figure 29), conduct the circuit, and also has a positioning and position limiting effect between the intermediate frames.

[0062] In some examples, the first middle frame 110 further includes an operating member 180, as shown in Figures 28 to 31, the operating member 180 including a rotating shaft 181, a link 182, and a push rod 183, the rotating shaft 181 being rotatably connected to the rear cover 50, the push rod 183 being connected to the movable part 1612, and the link 182 connecting the rotating shaft 181 and the push rod 183, and having a through hole for attaching a second fastener to the rotating shaft 181, the second fastener may be a socket head cap screw or the like to lock the rotating shaft 181 and stably and reliably connect the first electrical interface 162 and the second electrical interface 171. The rotating shaft 181 may rotate to drive the movable device 1612 by sliding it in the forward or reverse direction along the first direction, and the connection of the link 182 to the rotating shaft 181 allows for the use of a relatively long moment arm, the movement of the rotating shaft 181 is relatively labor-saving, and the movable device 1612 may be easily and reliably driven to slide in the forward or reverse direction along the first direction. The operating member 180 may remain mounted on the first middle frame 110 or may be a removable attachment tool.

[0063] In some examples, as shown in Figures 28 to 31, a handle portion 184 is provided on the link 182, and the handle portion 184 is a plate that protrudes from the link 182 and is provided along the direction of extension of the link 182. The handle portion 184 protrudes from the back surface of the rear cover 50 to facilitate operation by allowing the operator to rotate the entire rotating shaft 181 by manipulating the link 182 via the handle portion 184.

[0064] In some examples, as shown in Figures 28 to 30, the movable device 1612 is provided with a second position limiting groove 1613, and the push rod 183 is positioned within the second position limiting groove 1613, thereby allowing the push rod 183 to apply both pressing and tensile forces to the movable device 1612.

[0065] In some examples, as shown in Figures 28 to 30, a guide groove 1614 is provided in the movable part 1612, and at least a portion of the fixed part 1611 is located within the guide groove 1614, so that the movable part 1612 can move along a first direction under the positional constraint of the guide groove 1614, thereby limiting the maximum stroke of the movable part 1612, preventing damage to the interface due to overtightening of the connection between the first electrical interface 162 and the second electrical interface 171, preventing the associated cables from being excessively pulled, which is advantageous in ensuring structural stability and reliability.

[0066] In this experiment, the fastener 1611 is the rear cover 50 and integrally molded S The boss is perfectly positioned within the guide groove 1614, reducing the assembly procedure and ensuring structural integrity.

[0067] In some examples, a positioning device 190 is provided on the movable part 1612, and an elastic projection 191 connected to the rear cover 50 is provided on the positioning device 190, and the positioning device 190 has a first position (shown in Figure 33) and a second position (shown in Figure 34) in a first direction, and a first positioning hole 141 and a second positioning hole 142 are provided on the rear cover 50 of the first middle frame 110, and the positioning device 190 engages with the first positioning hole 141 and the second positioning hole 142 in the first and second positions, respectively. As shown in Figures 27 and 33, when the positioning device 190 engages with the first positioning hole 141 in the first position, the first electrical interface 162 is not connected to the second electrical interface 171. As shown in Figures 29 and 34, when the positioning device 190 engages with the second positioning hole 142 in the second position, the first electrical interface 162 is connected to the second electrical interface 171.

[0068] In some examples, the top of the fastener 1611 is further provided with a retaining piece 1615 to prevent the movable part 1612 from detaching from the fastener 1611, as shown in Figures 28 to 30, which is advantageous in ensuring structural reliability. A retaining plate 1616 is provided on the retaining piece 1615 to restrain the cable, preventing it from shifting, becoming entangled, or being subjected to unintended pressure.

[0069] In some examples, the first middle frame 110 is provided with a first circuit board electrically connected to the first electrical interface 162, and the second middle frame 120 is provided with a second electrical interface 17 1 A second circuit board is provided, which is electrically connected to the first circuit board. The first circuit board is connected to the display module 40 of the first middle frame 110, and the second circuit board is connected to the display module 40 of the second middle frame 120.

[0070] In some examples, the first and second intermediate frames 110 and 120 may both be similarly provided with the first electrical interface module 160 and the second electrical interface module 170, and the first and second electrical interface modules 160 and 170 may be provided opposite each other at the top and bottom of the intermediate frames to facilitate joining of multiple intermediate frames, and of course, the first interface module 160 and the second electrical interface module 170 may be provided opposite each other at the left and right sides of the intermediate frame.

[0071] As shown in Figure 32, the positioning device 190 includes a hollow bolt 192, a spring 193 and a steel ball 194 located inside the hollow bolt 192, and a portion of the steel ball 194 is pushed out to the end of the hollow bolt 192 by the spring 193. elasticity A projection 191 is formed The elastic projection 191 can be inserted into the first positioning hole 141 or the second positioning hole 142. The operator can determine whether the movable part 1612 slides to a predetermined position using the positioning structure of the spring 193 and steel ball 194. This prevents problems such as looseness, malfunction, and abnormal noise in the interface connection caused by the movable part 1612 sliding unintentionally, thus improving the reliability of the structure.

[0072] In this embodiment of the bonded display, when it is necessary to bring the two inner frames into contact or separate them, the operator can directly or indirectly drive the movable device 1612 located on the back surface of the rear cover 50 to slide the first electrical interface 162 toward the second electrical interface 171 along the first direction (sliding in the forward direction, the direction indicated by the arrow in Figure 29) to bring it into contact with the second electrical interface 171, or slide the first electrical interface 162 toward the second electrical interface 171 (sliding in the reverse direction, i.e., the opposite direction to the forward sliding direction) to detach it from the second electrical interface 171. The first electrical interface 162 and the second electrical interface 171 are brought into contact and separated by the linear sliding of the movable device 1612, eliminating the need for the installer to insert and remove cables in the narrow space on the side of the inner frame, avoiding the problem of power line connectors easily colliding with the internal circuit and causing circuit failure, resulting in convenient operation, a clean circuit, and good reliability of interface connections.

[0073] Example 3 For bonded displays, in order to ensure uniformity and completeness of the display, the requirements for mounting accuracy in the bonding process are very high. If there are many display means that need to be bonded, different mounting errors can accumulate, causing a large difference between the mounting position of a display means at a certain location and the expected position, affecting the mounting effect and potentially making mounting impossible. Therefore, improving mounting error tolerance while ensuring mounting accuracy is a problem that needs to be solved urgently. This embodiment provides an inner frame to address this problem. The inner frame in this embodiment may be applied to the bonded displays shown in each of the above embodiments, but is not limited thereto. It may also be applied to other bonded displays. In other words, the bonded display according to this embodiment may be implemented independently of each of the above embodiments, and is not limited thereto.

[0074] The basic configuration of the display means according to this embodiment includes three parts: a display module 40, an inner frame 10, and a rear cover 50. Referring to Figure 35, the inner frame 10 according to this embodiment includes four side beams 11, which are integrally molded to form the inner frame 10, and the inner frame 10 has a hollowed-out area within the structure enclosed by the four side beams 11. Regarding the display module as a whole, the outermost edge of the inner frame 10 is also the outermost edge of the display module 40, and the outermost edge of the display module 40 is at most flush with the inner frame 10 and not located outside the inner frame 10, thus ensuring support and protection of the display module 40 by the inner frame 10. 10 The four side beams 11 may be divided into an upper side beam located above, a lower side beam located below, and side beams located on both sides, depending on the positional relationship of their joints. In order to support and protect the central frame 10 from the display module 40, the central frame 10 may be provided with mounting components corresponding to the display module 40 (mounting methods include, but are not limited to, snap-fit, magnetic adsorption, screw fastening, adhesive, etc., and the embodiments of this application are not limited to specific mounting methods).

[0075] Adjacent display modules 40 Because they are connected, they are connected by multiple middle frames 10. Referring to Figure 36, the middle frames 10 It has multiple side beams 11, of which at least two Side beam 11 is They are set up facing each other. ,on the other hand Side beam 11 One side is provided with a pair of first fixing holes 131 and a first adjustment hole 132 that penetrates the side beam 11, while the other side is provided with at least one second fixing hole 133 corresponding to the first fixing holes 131. Figure 37 shows adjacent middle frames. 10 This is a schematic diagram showing the connection between adjacent display modules. 40 If it is implemented and connected, the side beam 11 at the corresponding position is also attached and connected.

[0076] Of the two opposing side beams 11, one side beam 11 is provided with a set of two holes: a first fixing hole 131 and a first adjustment hole 132. The first fixing hole 131 is for the adjacent display module 40 The first fastener 139 engages with the second fixing hole 133 and fastens the display module 40 Although the fixing between them is achieved, the action of the first adjustment hole 132 is performed by the first adjuster 138 on the display module 40 The goal is to fine-tune its position.

[0077] Here, the first adjustment hole 132 includes a screw hole, and the first adjuster 138 includes a first bolt member, the screw hole being positioned so as to adjust the gap between adjacent middle frames 10, after the first bolt member has been screwed in and extended, to abut against the side beam 11 of the adjacent middle frame 10.

[0078] In this embodiment, the first bolt member includes a bolt head 1381 and a stud 1382 (i.e., the first bolt member has a cylindrical portion of a screw), and the length of the stud 1382 is greater than the depth of the first adjustment hole 132, so that in the process of connecting and engaging the first bolt member with the first adjustment hole 132, the first bolt member abuts against the side beam 11 of the adjacent middle frame 10. 132It is permitted to protrude normally from there. In this embodiment, the first fastener 139 and the first adjuster 138 may both be bolts, each having a bolt head and a recess at the end of each nut for engagement of an operating tool (the cross-section of the recess may be a regular hexagon, a straight line, a cross shape, a triangle, etc., and is not limited in this embodiment), and can be tightened or loosened by the corresponding operating tool. The first adjustment hole 132 may be configured as a through hole that penetrates the side beam 11 on which it is positioned, and by providing an internal thread in the first adjustment hole 132, the corresponding first bolt member can be inserted into the first adjustment hole 132, and the relative position between the first bolt member and the first adjustment hole 132, in particular the protruding position of the first bolt member relative to the first adjustment hole 132, can be adjusted by the engagement of the threads.

[0079] To achieve the above objective, the stud of the first bolt member 1382 The length of the bolt member is greater than the depth of the first adjustment hole 132, thereby allowing the first bolt member to extend out of the first adjustment hole 132. When the first bolt member extends out of the first adjustment hole 132, it creates a pushing action, pushing the first bolt member into the adjacent display module. 40 By bringing it into contact with the middle frame 10, the display module 40 This allows for fine-tuning of the position. This fine-tuning can be performed on other display modules. 40 It can provide redundant space for mounting errors and other display modules 40 After the mounting position is shifted, position correction can be achieved by engaging it with the first bolt member via the first adjustment hole 132. 1382 This refers to the bolt head in the first bolt member. 1381 This refers to structures other than those mentioned above, and typically includes columnar structures with threaded portions, where the threaded portions may cover the entire columnar structure or only a part of it, and this embodiment is not limited to this.

[0080] In some examples, the first bolt member may be a stud, and the outer diameter of the end of the stud is smaller than the outer diameter of its threaded portion. Compared to a normal bolt, the stud does not have a stud head that is larger in dimensions than the threaded portion, has relatively uniform overall dimensions, and the outer diameter of its end is smaller than the outer diameter of the threaded portion. In this case, the length of the stud may be less than or equal to the depth of the first adjustment hole 132, and the stud may advance into the first adjustment hole 132 so that it sinks out so that the bottom of the stud protrudes from the first adjustment hole 132 and abuts against the side beam 11 of the adjacent middle frame 10. Referring to Figure 39, Figure 39 shows a specific mounting structure in which the first bolt member includes a stud 1383, and because the outer diameter of the end of the stud 1383 is smaller than the outer diameter of the threaded portion, the end of the stud 1383 is also inserted into the first adjustment hole 132, so that even if the length of the stud 1383 is less than the depth of the first adjustment hole 132, the stud 1383 abuts against the adjacent middle frame 10 side beam 11 This does not affect contact with the other components, and the length of the stud 1383 shown in Figure 39 is shorter than the depth of the first adjustment hole 132. Thus, after the stud 1383 and the first adjustment hole 132 are mounted, the stud 1383 can be fully retracted into the first adjustment hole 132, resulting in a good overall appearance of the inner frame 10 and not affecting the mounting of other components. During the mounting process, the stud 1383 can be screwed into and out of the first adjustment hole 132 by operating a corresponding operating tool. Figure 39 also shows that if there is a hexagonal socket recess at the end of the stud 1383, it can be rotated by operating a corresponding hex wrench.

[0081] Furthermore, large displays formed by joining multiple display means are typically used in harsh environments such as outdoors, where the ground is often uneven. In such scenarios, a first adjustment hole 132 is provided in the lower side beam 11, and the display module can be adjusted by the first adjustment tool 138. 40By adjusting the position between the display and the ground, the stability of the field mounting of the display can be improved. Specifically, as shown in Figure 40, the first adjustment hole 132 is positioned so that the first adjuster 138 penetrates the side beam 11 in which the first adjustment hole 132 is located from the outside to the inside of the middle frame 10. In the process of joining multiple middle frames 10, the lower side beam of the bottommost middle frame 10 is joined to the other middle frames 10 side beam 11 Since it does not need to be installed together with the other middle frame, the corresponding first adjuster 138 is also not required to be installed together with the other middle frame. 10 side beam 11 There is no need to contact it. In such cases, the mounting environment at the bottom, i.e., the display device 8 To adapt to the installation environment, the first adjustment tool 138 is inserted from the outside into the first adjustment hole 132, making it easy to operate the first adjustment tool 138 from the outside, and to adjust to the degree of unevenness of the base, ground, support frame, and other components on which it is placed, thereby allowing the display equipment to be adjusted. 8 The overall mounting balance can be achieved, and referring to Figure 41, A is the display device. 8 This indicates the mounting surface, such as the base, ground, or support frame on which the object is placed.

[0082] In some examples, the first fastener 139 may specifically include a second bolt member, the second bolt member including an integrally molded bolt head and stud. Referring to Figure 36, at least one of the first fixing hole 131 and the second fixing hole 133 is a through hole, and at least the other is a threaded hole, and the stud of the second bolt member is threaded through the through hole and then screwed into the threaded hole. The specific type of the second bolt member is a screw or bolt with a large nut portion, the male thread of the stud engaging with the female thread in the threaded hole to achieve fastening, and the stud may be used to restrict the position of the second bolt member. To accommodate the installation of the second bolt member, at least one of the first fixing hole 131 and the second fixing hole 133 is a through hole and the other is a threaded hole, and thus the second bolt member is connected to the threaded hole through the through hole, thereby achieving fastening between the corresponding side beams 11. For the stability of the connection, a gasket may be provided when connecting with the second screw fastener.

[0083] In some examples, both the first fixing hole 131 and the second fixing hole 133 are threaded holes. When both the first fixing hole 131 and the second fixing hole 133 are threaded holes, the male thread of the second bolt member can engage with the female threads of the first fixing hole 131 and the second fixing hole 133 simultaneously to achieve fastening, effectively improving the stability of the connection. Of course, in such cases, the thread directions of the first fixing hole 131 and the second fixing hole 133 should coincide and also coincide with the thread direction of the second bolt member.

[0084] In some examples, the first fixing hole 131 and the second fixing hole 133 are both through holes, and the first fastener 139 includes a third bolt member and a nut, where the threads in the stud of the third bolt member pass through the first fixing hole 131 and the second fixing hole 133 before being screwed into the nut. In addition to screwing the third bolt member into the female threads of the first fixing hole 131 and the second fixing hole 133, the first fixing hole 131 and the second fixing hole 133 may both be provided as through holes, and the engagement of the third bolt member and the nut provides fastening between adjacent side beams 11. In such scenarios, the first fixing hole 131 and the second fixing hole 133 may both be smooth through holes, and it is not necessary to provide female threads within them. The third bolt member can be directly passed through the first fixing hole 131 and the second fixing hole 133, and the end of the third bolt member can be secured in combination with a nut to connect the corresponding side beam 11. In some examples, to ensure mounting reliability and symmetry, two sets of first fixing holes 131 are provided on the same side beam 11, each located at the longitudinal end of the side beam 11.

[0085] In some examples, the line connecting the center points of the same pair of first fixing holes 131 and first adjustment holes 132 provided on the same side beam 11 is perpendicular to the longitudinal direction of the side beam 11. As shown in Figures 35 and 36, the positions where the first fixing holes 131 and first adjustment holes 132 are provided are located at the same coordinates on the side beam 11 with respect to the longitudinal direction of the side beam 11. In other words, by making the distance between the first fixing holes 131 and the first adjustment holes 132 somewhat small, the distance between the first fixing holes 131 and the first adjustment holes 132 can be kept small, and thus the curvature deformation during joining can be reduced.

[0086] In some examples, the first fixing hole 131 and the second fixing hole 133 may be provided in the upper and lower side beams 11, respectively, or in the left and right side beams 11. That is, referring to Figure 42, the first fixing hole 131 is in the middle frame 10The second fixing hole 133 is located in the lower side beam of the middle frame 10 The upper side beam is provided, and / or the first fixing hole 131 is located in the middle frame. 10 The second fixing hole 133 is located in one of the side beams of the middle frame. 10 It is provided corresponding to the other side beam. When provided on the two upper and lower side beams 11, it is possible to connect with the central frame 10 provided in the two upper and lower directions, while when provided on the two left and right side beams 11, it is possible to connect with the display modules provided in the two left and right directions. 40 This enables connection with the display device. 8 The joining process is always from bottom to top, meaning that the display module located at the bottom is joined first. 40 It is provided in the corresponding location, and then the display module is provided. 40 Display module above 40 An additional display module was added, located above and below the adjacent display module. 40 In a configuration in which a first fixing hole 131 and a second fixing hole 133 are provided to simplify the connection, the first fixing hole 131 is the middle frame 10 The lower side beam is provided in the middle frame, and the second fixing hole 133 is located in the middle frame 10 It is preferable that it is provided in correspondence with the upper side beam in such a structure. In such a structure, the display module located below 40 After it is installed, the second fixing hole 133 of the upper side beam is openly positioned upward, and the display module that is superimposed on it 40 The lower side beam is positioned such that the first fixing hole 131 corresponds to the second fixing hole 133, and then the corresponding first fastener 139 is inserted through the first fixing hole 131, passes through the first fixing hole 131, and then engages with the second fixing hole 133 to connect to the display module. 40To achieve overlapping and fixing, if adjustment is needed, the first adjuster 138 can be screwed into the first adjustment hole 132 to achieve screwing, and then the bottom of the first bolt member (i.e., the first adjuster 138) is positioned above the display module. 40 The display module extends from the bottom of the lower side beam and is located below. 40 By contacting the upper side beam, the two display modules 40 By increasing the gap between them, relative positional adjustments can be achieved.

[0087] In some examples, depending on the location of the first fixing hole 131, a corresponding first adjustment hole 132 is provided accordingly. Specifically, the first adjustment hole 132 is provided in the lower side beam 11 where the first fixing hole 131 is located, and the first adjuster 138 penetrates the lower side beam 11 from the inside to the outside of the middle frame 10 through the first adjustment hole 132. Alternatively, as shown in Figure 43, the first adjustment hole 132 is provided in the side beam 11 where the first fixing hole 131 is located, and the first adjuster 138 penetrates the side beam 11 from the inside to the outside of the middle frame 10 through the first adjustment hole 132.

[0088] In some examples, a second adjustment hole 137 may be included to improve adjustment flexibility, referring to Figure 44, where the second adjustment hole 137 is located in the same side beam 11 as the second fixing hole 133, and is offset from the first adjustment hole 132. In addition to the first adjustment hole 132 being located in the same side beam 11 as the first fixing hole 131, the second adjustment hole 137 may also be located in the same side beam 11 as the second fixing hole 133, and then adjusted by the second adjustment hole 137. To prevent interference between the first adjustment hole 132 and the second adjustment hole 137, the location where the second adjustment hole 137 is provided is offset from the first adjustment hole 132, and the second adjustment hole 137If the upper side beam 11 is provided, the second adjuster corresponding to the second adjustment hole 137 penetrates the upper side beam 11 from bottom to top, and in the adjustment process, after the second adjuster penetrates the upper side beam 11, the middle frame located above it 10 It abuts against the lower side beam 11, or the second adjustment hole 137 If the second adjustment tool is provided in the side beam 11, the second adjustment tool corresponding to the second adjustment hole 137 penetrates the side beam 11 from the inside to the outside, and in the adjustment process, after the second adjustment tool penetrates the side beam 11, the middle frame located on the side 10 It abuts against the side beam 11.

[0089] Frame of this embodiment 10 The first fixing hole is in the side beam 11 of the middle frame 10. 131 and second fixing hole 133 By providing this, two display modules 40 This enables joint mounting between the parts, and also provides a first adjustment hole. According to 132 First adjuster 138 and Display module 40 By enabling adjustment of the relative position between them, the display module 40 This improves the tolerance for installation errors and ensures the display effect of large-screen bonded displays.

[0090] In some examples, at least one side beam 11 is provided with a wire passage hole 134. The provision of the wire passage hole 134 allows the hollow area formed by the side beam 11 to communicate with the outside, thus enabling wiring to be routed, and the display module 40 The internal and external parts can be connected while ensuring the integrity of the structure. Referring to Figure 35, the wire passage holes 134 may be provided in any of the side beams 11, or in one or more side beams 11, and one or more wire passage holes 134 may be provided in the same side beam 11.

[0091] In some examples, continuing to refer to Figure 45, at least one side beam 11 may be provided with a collision prevention projection 135, the collision prevention projection 135 extending outward from the outer surface of the side beam 11, and at least one side beam 11 may further be provided with a collision prevention groove 136, the collision prevention groove 136 recessing inward from the outer surface of the side beam 11, adjacent to other display modules 40 It is aligned with the collision prevention projection 135 on the side beam 11. In accordance with the installation of the collision prevention projection 135, a collision prevention groove 136 is provided, and other display modules 40 The collision prevention protrusions 135 on the side beam 11 may be aligned with the collision prevention grooves 136. Furthermore, the collision prevention protrusions 135 and collision prevention grooves 136 may be provided on the same side beam 11, and the corresponding collision prevention protrusions 135 and collision prevention grooves 136 may be provided on other display modules accordingly. 40 It may also be provided on the same side beam 11, which can further improve the interlocking stability, and the display module 40 By improving the stability of the connections between them, the structural reliability of the configured joint indicator means can be ensured.

[0092] The bonded display according to this embodiment includes at least two sets of display means, where adjacent display means are fixed by engaging with a first fastener through first and second fixing holes in adjacent side beams. This allows for relative positional adjustment between groups of display means, thereby improving the tolerance of mounting errors for the display means and ensuring the display effect of the bonded display.

[0093] Example 4 Light panels are used in applications in the display or lighting fields, such as display modules and planar lighting fixtures. To support and fix the lamp panel, it is usually necessary to fix it with rigid members such as supports. This fixing ensures the flatness of the lamp panel and improves its strength after mounting. In the prior art, a common method for achieving fixation between the support and the lamp panel involves welding nut holes with multiple female threads to the mounting surface of the lamp panel, and then fixing the support to the lamp panel with a screw member having male threads. It is. The biggest drawback of this type of connection is that, with welding, the lamp panel is prone to localized thermal deformation, and once the solder is fixed, it is difficult to correct if the position is incorrect. This requires a high level of precision in the processing of the lamp panel, resulting in high processing costs and low production efficiency for the lamp panel assembly. This embodiment addresses this problem by providing a lamp panel assembly and its mounting method that significantly reduces the error rate while ensuring mounting reliability and improving production efficiency. Furthermore, the lamp panel assembly according to this embodiment may be applied to the display modules shown in each of the above embodiments, or to other display modules, planar lighting fixtures, etc. In other words, the lamp panel assembly according to this embodiment can be implemented independently of each of the above embodiments, and is not limited thereto.

[0094] As shown in Figures 46 to 49 and 50a, the lamp panel assembly 9 according to this embodiment includes a support 93, a lamp panel 90, and a connecting assembly 97. The connecting assembly 97 includes a first connector 98 and a second connector 99. The support 93 has a first surface 931 for connection to the lamp panel 90 and a second surface 932 facing the first surface 931. The lamp panel 90 has a third surface 901 for connection to the support 93 and a fourth surface 902 facing the third surface 901. A mounting hole 94 is provided in the support 93 and penetrates its first surface 931 and second surface 932.

[0095] The first connector 98 is tightly coupled to the second connector 99 via the mounting hole 94, forming a strong but separable connection. This connection can be removed with a tool or manually, while ensuring that there is no looseness at the connection point. The second connector 99 is attached to the first surface 931. Adhesive 92 is provided at the location of the second connector 99 on the third surface 901, and the adhesive 92 adheres the second connector 99 to the third surface 901 of the lamp panel 90, while the support 93 does not come into contact with the adhesive 92, thus avoiding difficulty in removal during the process of mounting the lamp panel assembly 9.

[0096] The lamp panel assembly according to this embodiment avoids localized thermal deformation of the lamp panel caused by welding processes used in the prior art by connecting the second connectors 99 using adhesive glue 92. Furthermore, the adhesive glue 92 is easier to maintain than solder, and even if the bonding position of a second connector 99 is incorrect, it is easy to correct.

[0097] The lamp panel assembly 9 in this embodiment may include, depending on the type, an indicator lamp panel or an illumination lamp panel. Specifically, the indicator lamp panel may include a direct-lit backlight lamp panel or an LED straight lamp panel. As shown in Figure 51, the light source provided in the lamp panel 90 includes a plurality of light-emitting chips provided on the light-emitting surface 902. The light-emitting chips are usually arranged at equal intervals in the lateral and vertical directions, that is, the distance between two adjacent light-emitting chips in the lateral direction is equal, and the distance between two adjacent light-emitting chips in the vertical direction is equal. Depending on the manufacturing process, die bonding of the light-emitting chips in the lamp panel 90 may occur before or after mounting the lamp panel 90 to the support 93.

[0098] Here, the material of the support 93 (also called the bottom case) is rigid, has a relatively stable form, and is resistant to elastic or inelastic deformation. For example, it may be a metal containing an alloy, or a hard plastic. The form of the support 93 is typically that of a lamp panel. 90The integrated structure is sized to match the lamp panel 90, and for example, the support 93 may be an integrated support plate sized to match the lamp panel 90, or a housing structure with a contour, the contour being a display that needs to be mounted on the lamp panel assembly 9. 8 It may be provided to match, and also, considering factors such as weight reduction or cost, the support 93 may be a frame structure consisting of some reinforcing ribs, insofar as it satisfies the conditions required for the specific application scene of the lamp panel assembly 9. The fixing of the lamp panel 90 and the support 93 is in the lamp panel assembly in this embodiment 9 This is achieved through the implementation method.

[0099] The structure of the lamp panel 90 in this embodiment mainly consists of a circuit board or various other boards, on which multiple light-emitting chips are mounted. Mounting holes 94 are provided to the connection assembly 97 to provide a basis for pre-connection with the support 93. These mounting holes 94 are arranged regularly on the support 93, that is, they are regularly provided on the support 93, and in the usual case, the number of connection assemblies 97 is equal to the number of mounting holes 94 This matches the number of mounting holes 94. Within the limits of the allowable structural strength, fewer connection assemblies 97 than the number of mounting holes 94 may be used, meaning that not all of the mounting holes 94 in the support 93 need to be used to secure the connection assemblies, thus providing a certain degree of design flexibility.

[0100] The connection between the connection assembly 97 and the support member 93 is removable. The connection assembly 97 includes two components, a first connector 98 and a second connector 99, to achieve this removable connection. The first connector 98 and the second connector 99 are connected through a through hole, forming a removable fastening between the three components: the first connector 98, the second connector 99, and the support member 93. Based on this removable connection design, once the connection is removed, separation can be achieved between the support member 93 and the lamp panel 90 after installation, and this separation operation does not break the adhesive structure between the connection assembly 97 and the lamp panel 90. In this embodiment, the first connector 98 and the second connector 99 are removablely connected by mounting holes 94 in the support member 93. Specific connection configurations include, but are not limited to, snap-fit ​​connections, mortise and tenon connections, and screw connections.

[0101] In various alternative embodiments, as shown in Figures 48 and 49, using a screw connection as an example, the first connector 98 includes a second threaded member with a male thread, and the second connector 99 includes a nut hole with a female thread, and the second threaded member and the nut hole achieve a removable connection by internal and external screwing. The second threaded member is located on the upper side of the support 93, and the threaded portion with the male thread may pass through the mounting hole 94 of the support 93. The nut hole is located on the lower side of the support 93, and the male thread of the second threaded member is inserted into the female thread of the nut hole, achieving a removable fixation between the second threaded member and the nut hole by internal and external screwing, and the bottom of the nut hole is bonded to the lamp panel 90 by adhesive glue 92, and in this way, after the subsequent mounting of the lamp panel 90 and the support 93 is completed, the lamp panel 90 and the support 93 can be separated by unscrewing the connection between the second threaded member and the nut hole, as shown in Figure 49. later Lamp panel assembly 9 This is a schematic diagram of the removal process.

[0102] In some examples, referring to Figure 48, to improve the reliability of adhesion between the nut hole and the lamp panel 90, the nut hole may specifically include an integrally molded threaded hole portion 991 and a base 992, the base 992 being closer to the lamp panel 90 than the threaded hole portion 991, the base 992 sealing the bottom of the nut hole to avoid contact between the adhesive 92 and the second threaded member, the bottom area of ​​the base 992 being larger than the bottom surface of the threaded hole portion 991 to increase the contact surface between the base 992 and the adhesive 92 and to strengthen the bonding force between the nut hole and the third surface 901 of the lamp panel 90. In this embodiment, the threaded hole portion 991 is cylindrical, and the shape of the base 992 is circular, and the base 992 The outer diameter of the base is larger than the outer diameter of the screw hole portion 991. In another embodiment, the base 992 The shape may be a square or an ellipse, or any other shape.

[0103] In the diagram As shown, in this embodiment, the lamp panel assembly 9 To realize the implementation, the connection assembly 97 is pre-attached to the support member 93, and in order to facilitate fixing the connection assembly 97 to the support member 93, at least a portion of the part where the second connector 99 (nut hole in this embodiment) and the first connector 98 (second screw member in this embodiment) are connected is fitted into the mounting hole 94, that is, the portion of the mounting hole 94 facing the first connector 98 can accommodate a portion of the first connector 98, and the portion of the mounting hole 94 facing the second connector 99 can accommodate a portion of the second connector 99 so that the mounting hole 94 has a position-restricting effect on the first connector 98 and the second connector 99, and pre-restricts the position of the second connector 99 when the second connector 99 is attached to the support member 93, making it easier to connect to the first connector 98. ru. Specifically, in this embodiment, the first connector 98 is a second threaded member, and the second threaded member has a bolt head portion 981 and a screw portion 982, with the diameter of the bolt head portion 981 being larger than that of the screw portion 982. The second connector 99 is a nut hole, and the mounting hole 94 is a stepped hole. Here. , mounting hole 94 of The first hole diameter 941 on the side facing the second threaded member is larger than the diameter of the screw portion 982 and smaller than the diameter of the bolt head portion 981, and the first hole diameter 942 on the side facing the nut hole of the mounting hole 94 is larger than the outer diameter of the nut hole. stomach. During installation, a portion of the nut hole can be fitted into the mounting hole 94 before connecting the second screw member to the nut hole, making the installation of the second screw member and the nut hole easy and resulting in high installation efficiency. The edge of the mounting hole 94 may be provided with a first protrusion 95 facing the lamp panel 90, and the first protrusion 95 can extend the mounting hole 94 and support the 93 The amount of material used can be reduced, and costs can be lowered. In this embodiment, the first protrusion 95 can abut against the base 992 of the nut hole, and the area of ​​the base 992 is larger than the edge of the first protrusion 95, separating the first protrusion 95 from the adhesive glue 92, and the first protrusion 95 This avoids the need to connect the connection to the adhesive glue 92. After the connection assembly 97 is fixed to the support 93, the support 93 with the connection assembly 97 mounted on it is obtained, and since the relative positions of each connection assembly 97 on the support 93 are already fixed, the individual connectors (first connectors) 98 or second connector 99 The position of the ) will not be misaligned with the positions of other connectors. Next, the lamp panel 90 is positioned horizontally, with the third surface 901 (mounting surface) of the lamp panel 90 facing upwards, and the support 93 on which the connection assembly 97 is mounted is positioned above the lamp panel 90.

[0104] The mounting surface is provided with multiple connection areas 903 corresponding to the locations of the second connector 99, and adhesive glue 92 is pre-applied to the connection areas 903 in preparation for bonding the subsequent lamp panel 90 to the support. Referring to Figure 52, this figure shows each connection area 903 provided on the mounting surface of the lamp panel 90 (i.e., the third surface 901), and the adhesive glue 92 provided on the mounting surface of the lamp panel 90 is located in each connection area 903, and the position of the connection area 903 corresponds to the position of the second connector 99 provided on the support 93. The position of the connection area 903 here corresponds to the position of the second connector 99, and the two must coincide perfectly. In practice, however, it is sufficient that when the adhesive glue 92 is applied, each second connector 99 is properly bonded to the third surface 901 via the adhesive glue 92, and that the bonding result satisfies the required bonding strength, and a certain positional misalignment between the second connector 99 and the connection area 903 is permitted when actually bonding. The third surface 901 is the corresponding surface on the lamp panel 90 when the lamp panel 90 and the support 93 are connected, and generally faces the light-emitting surface of the lamp panel 90 (in this embodiment, the fourth surface 902 of the lamp panel, shown in Figure 51), where the light-emitting surface refers to the surface on which the light-emitting chip is provided. After the lamp panel 90 is manufactured, its light-emitting surface may be very flat and it may be placed horizontally downwards.

[0105] Next, the second connector 99 is aligned with the adhesive 92, and the third surface 901 of the lamp panel 90 and the first surface 931 of the support 93 are pressed together to bond the second connector 99 to the adhesive 92, while preventing the support 93 from contacting the adhesive 92. Each of the second connectors 99 is bonded to the connection area 903 by the adhesive 92. After the adhesive 92 has cured, the desired lamp panel assembly can be formed. Since the support 93 and the connection assembly 97 are detachable, the lamp panel 90 and the support 93 are also detachable after the adhesive 92 has cured, so as to separate the support 93 from the lamp panel 90.

[0106] In this embodiment, in the crimping process, a certain gap is created between the second connector 99 and the lamp panel 90 to accommodate the adhesive glue 92. A second protrusion 96 is provided on the support 93, facing the lamp panel 90. The second protrusion 96 is the part of the support 93 closest to the lamp panel 90, and the distance from the second protrusion 96 to the lamp panel 90 is greater than the distance from the second connector 99 to the lamp panel 90. In this embodiment, the second protrusion 96 is in contact with the lamp panel 90. In another embodiment, other components such as a spacer may be provided between the second protrusion 96 and the lamp panel 90. In this embodiment, the second protrusion 96 makes the force acting on the lamp panel 90 by the first protrusion 95 relatively uniform, and the second protrusion 96 is in contact with the lamp panel 90 It can surround the edge of the lamp panel 90 The second protrusions 96 are provided in strip form and in multiple quantities, and are located on the edges and intermediate portions of the support member 93, so as to provide dust protection to the edge portion. In one embodiment, the second protrusions 96 may be in a columnar shape such as a cylindrical or prismatic shape, and are arranged dispersedly on the first surface 931 of the support member 93 (i.e., each second protrusion 96 A gap is formed between them for air to circulate, which creates more space between the support 93 and the lamp panel 90, which is advantageous for heat dissipation of the lamp panel 90. Since the second protrusion 96 is the part closest to the lamp panel 90, when the lamp panel 90 and the support 93 are pressed together, the second protrusion 96 acts as a support point, preventing the second connector 99 from pressing too hard on the adhesive glue 92, ensuring that the adhesive glue 92 has a constant thickness, and the adhesive glue 92 and the lamp panel 90 and the second connector 99 To ensure adhesive strength with the adhesive, 92 This reduces the amount of adhesive that protrudes onto the outer circumference of the second connector 99. Because the adhesive 92 has a certain containment space and the adhesive 92 has good plasticity, the second connector 99Even if the bottom or connection area is not flat, it does not affect the accuracy of the connection between the second connector 99 and the first connector 98. If the pre-connected position and orientation of the first connector 98 and the second connector 99 are correct, the accuracy of the connection between the first connector 98 and the second connector 99 can be maintained after the adhesive glue 92 has hardened. Thus, the plasticity of the adhesive glue 92 reduces the error rate in the bonding process.

[0107] In another embodiment, as shown in Figure 50b, the third surface 901 (mounting surface) of the lamp panel 90 may be oriented downwards, and the support 93 on which the connection assembly 97 is mounted may be positioned below the lamp panel 90. The first surface 931 of the support 93 is placed horizontally, and then adhesive glue 92 is pre-applied to the bottom of the second connector 99, after which the lamp panel 90 and the support 93 are pressed together. After the adhesive glue 92 has cured, the lamp panel assembly 9 is also obtained. The adhesive glue 92 is provided to bond the lamp panel 90 and the support 93, but in order to maintain the flatness of the lamp panel 90, the adhesive glue 92 provided in this embodiment has a certain thickness. ru. In this structure, the thickness of the adhesive glue 92 itself does not affect the flatness of the lamp panel 90, and the second connector in a different orientation 99 and mounting surface 901 It can be adapted for bonding between the two. Specifically, by ensuring that the settable thickness of the adhesive 92 is greater than or equal to a first preset threshold, the second connector 99 on the support 93 can be brought into sufficient contact with the adhesive 92 during mounting. In this case, even if the second connector 99 is tilted, or if the position of the second connector 99 is misaligned with the corresponding preset mounting area, the adhesive will still adhere. 92 The second connector 99 is properly bonded to it, and the relative positions between all the second connectors 99 after bonding may be fixed.

[0108] In some cases, to reduce the overflow of adhesive 92 due to too much adhesive being applied, the thickness of the adhesive 92 may be set to be below a second preset threshold when adhesive 92 is applied to each preset connection area 903 of the third surface 901. Here, the second preset threshold is greater than the first preset threshold, and an upper limit is set for the thickness of the adhesive 92 to prevent excessive application of adhesive 92 from overflowing from the preset connection areas 903 during bonding and affecting the function of other parts of the lamp panel 90. Furthermore, in addition to being able to set an upper limit on the thickness of the adhesive 92, a first adhesive storage groove 904 may be provided in the connection area 903 to reduce the possibility of adhesive overflow (see Figure 50b). That is, several recesses are provided at the bottom of the connection area 903 to place the adhesive 92 and restrict its flow, and the first adhesive storage groove 904 ensures that the adhesive 92 has a certain thickness, thereby strengthening the adhesive force between the adhesive 92 and the lamp panel 90 and the second connector 99. Additionally, a second adhesive storage groove 993 may be provided at the bottom of the second connector 99 to reduce the possibility of adhesive overflow (see Figures 50a and 51). That is, several recesses are provided at the bottom of the second connector 99, allowing excess adhesive 92 to be placed in the recesses, reducing the likelihood of the adhesive 92 overflowing when the second connector 99 is pressed. The shape of the recess may be any of the following shapes: a "straight" shape, a "cross" shape, a circle, an ellipse, a wave shape, a grid shape, etc. The recess may increase the bonding surface between the adhesive 92 and the second connector 99 in order to strengthen the adhesion between the adhesive 92 and the lamp panel 90 and the second connector 99.
