Description

Installation component and splicing screen Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a wall-mounted component and a spliced ​​screen. Background Art

[0002] A splicing screen is a display device that combines two or more display screens to form a larger screen, providing a larger display image and better visual effects. Due to its various advantages, splicing screens are increasingly in demand in commercial displays, monitoring centers, classrooms, conference rooms, large-scale event venues, and other places.

[0003] In the related art, when using spliced ​​screens, installers are required to mount each screen to a wall or other mounting surface to combine multiple screens into a larger display device. However, in the related art, when installing spliced ​​screens, installers are required to lift the screens and mount them to the mounting surface. This makes it difficult to align the positions of adjacent screens, which can easily lead to problems such as large splicing gaps and step differences between adjacent screens, thus affecting the user experience after splicing.

[0004] Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a splicing screen with an installation component, which can improve the position alignment effect between adjacent screen bodies, improve the splicing gap and step difference problems after the adjacent screen bodies are spliced ​​together, provide a better user experience of the splicing screen, and make the installation process of the splicing screen more convenient and time-saving.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] A mounting assembly, the mounting assembly being used to mount a screen body to a mounting surface and to adjust the position of the screen body; the mounting assembly comprising a first wall-mounting assembly and a second wall-mounting assembly;

[0011] The first wall-mounted assembly is provided on the rear side of at least one of the screen bodies; the first wall-mounted assembly is used to mount the screen body to a mounting surface and to adjust the left-right position of the screen body; the first hanging member is connected to the screen body, and the first support member supports the first hanging member, and when the screen body drives the first hanging member to move in the left-right direction relative to the first support member, the rolling member rotates;

[0012] The rear side of at least one of the screen bodies is provided with the second wall-mounted component; the second wall-mounted component is used to install the screen body to the installation surface, and to adjust the up and down position and / or front and back position of the screen body; the second hanging member is connected to the screen body, and the second support member supports the second hanging member; the first adjusting member is used to adjust the up and down position of the screen body by adjusting the up and down position of the first hanging member, and the second adjusting member is used to adjust the front and back position of the screen body by adjusting the front and back position of the first hanging member.

[0013] The beneficial effects of the present application are as follows: when the installation component is applied to the installation of a single screen in a spliced ​​screen, it is beneficial to make the left and right position of the screen easier to adjust during the installation process, and to make the front and rear position and / or the up and down position of the screen easier to adjust, thereby making the splicing gap between adjacent screens smaller, the step difference smaller, and the flatness better, making the splicing screen installation process more time-saving and labor-saving, and making the splicing screen installation effect and use effect better.

[0014] In a spliced ​​screen, the relative positions of adjacent screens in the left-right, up-down, and front-to-back directions can be adjusted via the first and second mounting assemblies. This makes splicing operations between adjacent screens easier during installation, allowing for more accurate left-right splicing, up-down alignment, and front-to-back alignment.

[0018] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0019] In the description of this application, unless otherwise specified or limited, the terms "connected" and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0020] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0021] A splicing screen is formed by splicing two or more display screens together to form a larger display screen. A splicing screen can also be called a splicing display device or a splicing interactive flat panel. In the field of display equipment, with the development of market demand, the application of double-splicing products made of two screens and multi-splicing products made of three or more screens is becoming more and more widespread. For example, splicing screens can be used in shopping malls, exhibitions and other places to display products, advertisements and other information; they can be used in monitoring centers to display multiple monitoring screens; they can be used in conference rooms or classrooms to display meeting content or teaching content, and provide touch interaction functions. Splicing smart blackboards used in classrooms, splicing conference flat panels used in conference rooms, and splicing interactive flat panels used in exhibition halls are all splicing screens.

[0022] In the related art, when installing a spliced ​​screen, each independent screen is generally mounted on a mounting surface, which is generally a wall surface. However, during the installation of each screen of the spliced ​​screen, the relative positioning of the screens may not meet the requirements due to various reasons. Problems may arise, such as large splicing gaps between adjacent screens, uneven widths of splicing gaps between adjacent screens, uneven vertical alignment between adjacent screens, and uneven front-to-back differences between adjacent screens.

[0023] Here are some examples of problems that currently exist in the installation of splicing screens:

[0024] First, due to the uneven wall surface, the display surfaces of adjacent screens are not in the same plane, which will cause a front-to-back segment difference between the adjacent screens, resulting in the display surface of one screen being forward and the display surface of the other screen being backward at the junction of the adjacent screens. For example, in the two screens 10 shown in FIG20 , one screen 10 is tilted backward relative to the other screen 10. The front-to-back segment difference between the screens not only makes the spliced ​​screen unsightly and affects the integrity; for spliced ​​screens with writing and touch functions, when the writing track needs to cover two adjacent screens, the front-to-back segment difference between the screens will cause writing to be stuck, affecting the writing experience.

[0025] Second, during installation, the support member is fixed to the mounting surface, and the screen body is then hung on the support member to provide support for the screen body. However, when the support member is installed on the mounting surface, the actual installation position of the support member may be higher or lower than the set installation position due to installation errors by the installer. This will cause the upper and lower positions of the entire screen body to be inaccurate. The upper and lower positioning inaccuracy may be that one of the screen bodies is lower than the other screen body, or one of the screen bodies may be tilted as a whole. For example, Figure 21 shows the left screen body 10 tilted to the left as a whole, and Figure 22 shows the right screen body 10 tilted to the right as a whole. The upper and lower positions of adjacent screen bodies are not aligned, which not only affects the overall appearance. As shown in Figures 21 and 22, if one of the screen bodies 10 is tilted as a whole, a seam may appear between the adjacent screen bodies 10, and the width of the seam is inconsistent at different positions. For splicing screens with writing and touch functions, when the writing track needs to cover two adjacent screen bodies, the seam will cause the writing track to be interrupted, affecting the writing experience.

[0026] Third, the weight of a single screen in a spliced ​​screen is relatively heavy. Taking a spliced ​​smart blackboard or a spliced ​​interactive tablet as an example, a single 86-inch display screen weighs about 65 kg. During installation, the first screen is generally installed first, and then the second screen. When installing the second screen, the second screen needs to be close to the first screen, so that the sides of the two screens are as close as possible. However, due to the heavy weight of a single screen, it is difficult for the installer to effectively control the position of the second screen by simply moving the second screen close to the first screen, which will cause a splicing gap between the two screens, and it is also easy to have an uneven splicing gap. For example, Figure 23 illustrates the situation where a splicing gap appears between the screens when two screens 10 are spliced. The splicing seams between adjacent screens, as well as the uneven splicing seams, will not only cause black lines in the display of the spliced ​​screen, affecting the display effect, but also affect the appearance and integrity of the spliced ​​screen, and also affect the writing and touch experience.

[0027] Of course, in addition to the specific problems mentioned above during the installation process, other factors may also cause the left and right, up and down, front and back positions of the screens to be inaccurate and difficult to adjust during installation, thus affecting the integrity and use effect of the splicing screen.

[0028] It should be noted that in this application, in order to facilitate the illustration and description of the relative positions of the various components, in the accompanying drawings, the left and right directions of the splicing screen and each component are indicated by the x direction, the up and down directions of the splicing screen and each component are indicated by the y direction, and the front and back directions of the splicing screen and each component are indicated by the z direction. When the splicing screen is used, the front side of the splicing screen is the side facing the user, and the back side is the side facing the installation surface. For the convenience of description in this application, the left and right directions and the up and down directions of the splicing screen and each component refer to the left and right directions and the up and down directions of the user when the splicing screen is used and the display surface of the splicing screen is facing the user. In other cases, the left and right directions and the up and down directions of the splicing screen and each component may also be other directions.

[0029] Based on the installation difficulties of splicing screens in the related art, with reference to Figures 1 to 19 and 28, the present application provides a mounting assembly and a splicing screen.

[0030] The splicing screen includes multiple screens and mounting components, and the mounting components include a first hanging component and a second hanging component. The first hanging component is used to install the screen to the mounting surface, and is used to adjust the left and right position of the screen. The second hanging component is used to install the screen to the mounting surface, and is used to adjust the front and back position and / or the up and down position of the screen. Through the two hanging components, while realizing the installation of the screen, it is convenient to adjust the left and right position, front and back position, and up and down position of the screen, making the splicing operation between adjacent screens easier, and making the left and right splicing, up and down alignment, and front and back alignment between adjacent screens more accurate, thereby improving the installation effect of the splicing screen, improving the appearance and integrity of the splicing screen, and improving the user experience of the splicing screen. The splicing screen has higher flatness and smaller splicing gaps. The display effect of the splicing screen meets higher requirements and provides a better writing experience.

[0031] For the convenience of description, this application takes a spliced ​​screen as an example to illustrate the installation components and the spliced ​​screen.

[0032] Based on the installation difficulties of splicing screens in the related art, with reference to Figures 1 to 19 and 28, the present application provides a mounting assembly and a splicing screen.

[0033] The splicing screen includes a plurality of screen bodies 10 and mounting components, and the mounting components include a first hanging component and a second hanging component. The first hanging component is used to install the screen body 10 to the mounting surface, and is used to adjust the left and right position of the screen body 10. The second hanging component is used to install the screen body 10 to the mounting surface, and is used to adjust the front and back position and / or the up and down position of the screen body 10. Through the two hanging components, while realizing the installation of the screen body 10, it is convenient to adjust the left and right position, front and back position, and up and down position of the screen body 10, making the splicing operation between adjacent screen bodies 10 easier, and making the left and right splicing, up and down alignment, and front and back alignment between adjacent screen bodies 10 more accurate, thereby improving the installation effect of the splicing screen, improving the appearance and integrity of the splicing screen, and improving the user experience of the splicing screen. The splicing screen has higher flatness and smaller splicing gaps. The display effect of the splicing screen meets higher requirements and provides a better writing experience.

[0034] For the convenience of description, this application takes a spliced ​​screen as an example to illustrate the installation components and the spliced ​​screen.

[0035] Please refer to Figures 1 to 19 and 28. The splicing screen includes multiple first wall-mounted components 20 and second wall-mounted components 30. Multiple screen bodies 10 refer to two or more screen bodies 10. The screen body 10 can be, but is not limited to, a display screen. Among the multiple screen bodies 10, each screen body 10 is arranged adjacent to at least another screen body 10, so as to form a larger screen by assembling multiple screen bodies 10. When the splicing screen is installed, a wall-mounted component is set on the rear side of each screen body 10, and the screen body 10 is installed to the installation surface through the wall-mounted component. The installation surface refers to a wall surface, a curtain wall surface, etc. In some cases, the installation surface may also be an installation surface provided by a steel frame or a steel plate.

[0036] The first wall-mounted component 20 is used to support the screen body 10 and to facilitate adjustment of the position of the screen body 10 in the left-right direction. The first wall-mounted component 20 is provided on the rear side of at least one screen body 10. The first wall-mounted component 20 includes a first hanging member 21, a first support member 22, and a rolling member 23. The first hanging member 21 can be fixed to the screen body 10 by screws or the like, and the first support member 22 can be fixed to the mounting surface by screws or the like. The first support member 22 supports the first hanging member 21, thereby supporting the screen body 10 through the first support member 22. Between the first hanging member 21 and the first support member 22, at least one extends in the left-right direction so that the first hanging member 21 can move left and right on the first support member 22. The rolling member 23 is provided between the first hanging member 21 and the first support member 22. The rolling member 23 can be, but is not limited to, a rotatable pin, a bearing, a ball, etc. The rolling member 23 abuts against the first support member 22 or the first mounting member 21. When the first mounting member 21 moves left and right relative to the first support member 22 under an external force, the rolling member 23 rotates due to friction, thereby reducing the frictional resistance between the first mounting member 21 and the first support member 22. The first wall-mounting assembly 20 not only provides a track for the left and right lateral movement of the screen 10, but also reduces the resistance to the left and right lateral movement of the screen 10 by configuring the rolling member 23.

[0037] The second wall-mounted component 30 is used to support the screen body 10 and to adjust the position of the screen body 10 in the up and down direction and / or the front and back direction. The second wall-mounted component 30 is provided on the rear side of at least one screen body 10. The second wall-mounted component 30 includes a second hanging member 31, a second support member 32, and also includes a first adjustment member 33 and / or a second adjustment member 34. The second hanging member 31 is mounted and fixed to the screen body 10, and the second support member 32 is used to be mounted and fixed to the mounting surface. The second support member 32 supports the second hanging member 31, thereby supporting the screen body 10 through the second support member 32. When the second wall-mounted component 30 includes the first adjustment member 33, the first adjustment member 33 can be operated manually or automatically by the device to adjust the up and down position of the second hanging member 31 through the first adjustment member 33, and the hanging member support member thereby adjusts the up and down position of the screen body 10. When the second wall-mounted component 30 includes a second adjusting member 34 , the second adjusting member 34 can be operated manually or automatically by a device to adjust the front and rear position of the second hanging member 31 , and the hanging member support member thereby adjusts the front and rear position of the screen body 10 .

[0038] It should be noted that, in the present application, adjusting the upper and lower positions of a certain component means: the position of the component can only be adjusted upward, or the position of the component can only be adjusted downward, or the position of the component can be adjusted both upward and downward. In the present application, adjusting the front and rear positions of a certain component means: the position of the component can only be adjusted forward, or the position of the component can only be adjusted backward, or the position of the component can be adjusted both forward and backward. It can be understood that, for the screen body 10 with the first wall-mounted component 20 provided on the rear side, when the screen body 10 moves to the left or right, it can drive the first hanging component 21 to move to the left or right. For the screen body 10 with the second wall-mounted component 30 provided on the rear side, when the second hanging component 31 moves upward, downward, forward, or backward, the second hanging component 31 can drive the screen body 10 to follow its movement.

[0039] In one embodiment, the rear side of each of the two adjacent screens 10 arranged in the left-right direction is provided with a first wall-mounting assembly 20. In other embodiments, the rear side of only one of the two adjacent screens 10 arranged in the left-right direction is provided with a first wall-mounting assembly 20.

[0040] In one embodiment, the rear side of each screen 10 is provided with a second wall-mounted assembly 30. In other embodiments, only one of every two adjacent screens 10 is provided with a second wall-mounted assembly 30 on its rear side.

[0041] In order to facilitate the understanding of the splicing screen installation process, a splicing screen installation method is provided by taking an example in which a splicing screen includes two screen bodies 10, and a first wall-mounted component 20 and a second wall-mounted component 30 are provided on the rear side of the second screen body 10, and combining Figures 2 and 3:

[0042] S1: Install the first support members 22 on two installation areas corresponding to the left and right screen bodies 10 respectively on the installation surface.

[0043] S2: Install the second support members 32 on two installation areas on the installation surface corresponding to the left and right screen bodies 10 respectively; install multiple second support members 32 in each installation area.

[0044] S3: A first hanging member 21 and a second hanging member 31 are provided on the rear side of the first screen 10. The first hanging member 21 is hung on the first support member 22, thereby hanging the first screen 10 on the first support member 22. On the rear side of the first screen 10, the first support member 22 supports the first hanging member 21 at least from bottom to top.

[0045] S4: A first hanging member 21 and a second hanging member 31 are provided on the rear side of the second screen 10. The first hanging member 21 is hung on the first support member 22, so that the second screen 10 is hung on the first support member 22. On the rear side of the second screen 10, the first support member 22 supports the first hanging member 21 at least from bottom to top.

[0046] S5: Push the first screen 10 left and right, and / or push the second screen 10 left and right, until the left and right sides of the two screens 10 abut against each other. At this point, on the rear side of each screen 10, at least a portion of the first hanging member 21 is located above the first support member 22, and at least a portion of the second hanging member 31 is located above the second support member 32.

[0047] S6: Check the vertical alignment of the two screen bodies 10. If the vertical alignment is not satisfied (as shown in Figures 21 and 22, the upper side edges 12 of the two screen bodies 10 are not in a straight line, or the lower side edges 13 are not in a straight line), adjust the first adjustment member 33 in the second wall-mounted component 30 on the rear side of at least one screen body 10 to adjust the position of the screen body 10 in the vertical direction so that the two screen bodies 10 are aligned as much as possible; if the vertical alignment is satisfied (as shown in Figure 24, there is no vertical position difference between the two screen bodies 10 or the vertical position difference is within the error range), do not operate the first adjustment member 33.

[0048] S7: Check the front-to-back alignment of the two screens 10. If the front-to-back alignment is not satisfied (as shown in FIG. 20 , the display surfaces 14 of the two screens 10 are not in the same plane), adjust the second adjustment member 34 in the second wall-mounted assembly 30 on the rear side of at least one screen 10 to adjust the position of the screen 10 in the front-to-back direction, so that the two screens 10 are aligned as much as possible front-to-back to avoid front-to-back step differences between adjacent screens 10. If the front-to-back alignment is satisfied, do not operate the second adjustment member 34.

[0049] Optionally, in some installation steps, after the left-right relative position, the front-back relative position, and the top-bottom relative position of the two screen bodies 10 meet the requirements, the two screen bodies 10 are connected and fixed by the connecting member 24 .

[0050] The order of steps S5, S6, and S7 can be reversed. However, it is understood that by first bringing the left and right screens 10 as close together and minimizing the gap between the two screens 10, it is easier to check the vertical alignment and front-to-back alignment between the two adjacent screens 10, the inspection results are more accurate, and the vertical and front-to-back position adjustment of the screens 10 is also more accurate. The above installation method is only an example, and the spliced ​​screen of this application is not limited to being installed using the above method.

[0051] It should be noted that in step S6, the operator can mainly use the first adjustment member 33 to adjust the position of the screen body 10 upward. When the distance the screen body 10 is adjusted upward exceeds the expected adjustment distance, the first adjustment member 33 can be used to adjust the position of the screen body 10 downward. For example, when the upper side 12 of the first screen body 10 is higher than the upper side 12 of the second screen body 10, the first adjustment member 33 on the rear side of the second screen body 10 can be operated to adjust the overall position of the second screen body 10 upward until the upper side 12 of the second screen body 10 is flush with the upper side 12 of the first screen body 10.

[0052] It is understandable that when no rolling member 23 is provided between the first hanging member 21 and the first wall hanging member, and when the left and right directions of the splicing screen and its components are consistent with the left and right directions when used by the user, the screen body 10 is erected and the screen body 10 is hung on the first wall hanging member through the first hanging member 21. If the screen body 10 needs to be moved left and right, due to the heavy weight of the screen body 10, a large friction force will be generated between the first hanging member 21 and the first wall hanging member, resulting in the first hanging member 21 and the screen body 10 being difficult to move left and right when the first wall hanging member supports the first hanging member 21. In this way, multiple installers are required to lift the screen body 10 and separate the first hanging member 21 from the first wall hanging member before the left and right position of the screen body 10 can be adjusted, which is troublesome and laborious. The splicing screen of the present application is configured with a rolling member 23 in the first wall-mounted component 20, which can reduce the friction resistance of the first hanging member 21 and the screen body 10 moving left and right when the first wall-mounted member supports the first hanging member 21. When the left and right position of the screen body 10 needs to be adjusted, there is no need for multiple installers to lift the screen body 10 again. The installers can directly push the screen body 10 left and right, thereby reducing the labor intensity and difficulty of the installers in adjusting the left and right screen bodies 10 to a state where the sides are against each other, thereby improving the splicing tightness between adjacent screen bodies 10, reducing or avoiding splicing gaps, and the adjustment process is easier.

[0053] The splicing screen of the present application is also equipped with a first adjustment member 33 and / or a second adjustment member 34 in the second wall-mounted component 30, which facilitates the vertical alignment and front-to-back alignment of the two screen bodies 10, improves the alignment of the two screen bodies 10, improves the integrity, reduces or avoids the splicing seams, reduces or avoids the front-to-back step difference, improves the user experience, and improves the writing experience of the splicing screen with touch writing function.

[0054] The splicing screen of the present application can adjust the position of the screen body 10 in multiple directions, such as left and right, up and down, front and back, during installation, thereby solving the problems of inaccurate left and right position of the screen body 10, misalignment of the up and down position, misalignment of the front and back position, and uneven size of the splicing gaps and uneven step differences between the screen bodies 10 caused by the tilt of the screen body 10 after being hung on the wall. The splicing gaps between adjacent screen bodies 10 can be reduced or eliminated, and the step differences between adjacent screen bodies 10 can be made smaller and flatter. For splicing screens with a large number of screen bodies 10, the position of each screen body 10 in multiple directions is easy to adjust, so that the splicing integrity between each two screen bodies 10 is better, so that the installation effect of the entire large splicing screen is better, uniform small gaps or seamless splicing are achieved, and the display surface 14 of the splicing screen is flat, the display effect is better, and the touch writing experience is better.

[0055] The spliced ​​screen of the present application reduces the difficulty of on-site installation, improves the problems of inconvenient lifting and difficult installation caused by the heavy weight of the screen body 10 at the installation site, and makes installation more convenient and time-saving.

[0056] It is understandable that in some cases in the relevant technology, the requirements for the position of the screen 10 are not high. When installing the screen 10, the screen 10 is directly lifted manually to adjust the position of the screen 10. Although it is impossible to achieve more precise position adjustment of the screen 10 due to the heavy weight of the screen 10 and the difficulty of multi-person collaboration, it can meet the installation requirements. However, for some splicing screens, there are high requirements for the relative position between the screen bodies 10. For example, after the overall installation of the splicing screen is completed, it is required that when the splicing screen is viewed from the front, the display area of ​​the splicing screen has no gaps and no black edges, so that when the splicing screen displays the picture, the user feels that the entire splicing screen is a whole large screen rather than multiple small screens, and it is required that the front surface of the splicing screen is flat when viewed from the left or right side of the splicing screen. At this time, the first wall-mounted component 20 and the second wall-mounted component 30 of the present application are used to install the screen body 10, and the left and right, front and back, and up and down positions of the screen body 10 can be adjusted to meet higher screen body 10 position requirements and splicing requirements between screen bodies 10.

[0057] For example, in one embodiment, when the individual screen bodies 10 of the spliced ​​screen are installed on the mounting surface, the position requirements between adjacent screen bodies 10 are relatively high. However, by installing the screen bodies 10 using the first wall-mounted assembly 20 and the second wall-mounted assembly 30 of the present application, the need for more precise adjustment of the position of the screen bodies 10 can be met. As shown in Figures 25 to 28, the screen body 10 is the main display screen; the main display screen includes a screen fixing structure 81 and a main display module, and the spliced ​​screen includes a secondary display module 90, both of which are used to display images. The secondary display module 90 can be, but is not limited to, a miniLED, which is a small LED display module. The main display module includes a display panel 82 and a glass cover plate 83. The display panel 82 is fixed to the front side of the screen fixing structure 81, and the glass cover plate 83 is fixed to the front side of the display panel 82. The edge area of ​​the first side of the display panel 82 is a first edge area 821. The first sides of adjacent display panels 82 are close to each other, and the glass cover plates 83 avoid the first edge area 821 to expose the front side of the first edge area 821. A mounting groove is formed between adjacent screen fixing structures 81 and adjacent glass cover plates 83. The auxiliary display module 90 is mounted in the mounting groove, and the auxiliary display module 90 covers the front side of the first edge area 821. The display panel 82 can be, but is not limited to, a liquid crystal panel. Optionally, the glass cover plates 83 on both sides of the auxiliary display module 90 respectively abut against each other.

[0058] As shown in FIG25, when the splicing screen is in the state of being installed, a secondary installation groove 801 is formed between adjacent main display modules. As shown in FIG26 and FIG27, the secondary display module 90 is arranged in the secondary installation groove 801, and the two sides of the secondary display module 90 respectively abut the main display modules on both sides. Firstly, by eliminating the outer frame surrounding the outer side of the main display module in conventional technology, the black edge caused by the thickness of the outer frame can be avoided; secondly, by adding the secondary display module 90 between adjacent main display modules, even if there is a certain black edge area at the edge of the display panel 82 of the main display screen, the black edge area can be covered by the secondary display screen. Thus, after the entire splicing screen is installed, the following effect is achieved: As shown in FIG27, the left main display module, the secondary display module 90, and the right main display module seen from the front of the splicing screen are all areas that can display images, without black edge areas, and the overall display effect is better; taking the image example indicated by the dotted line in the figure, when the splicing screen displays the image of a mountain, the overall image is not cut off. It is understandable that after the adjacent screen bodies 10 are installed on the installation surface, before the auxiliary display module 90 is installed between the adjacent main display modules, the left and right positions between the adjacent screen bodies 10 need to be more accurately adjusted through the first wall-mounted component 20 of the present application, so that the left and right sides of the auxiliary display module 90 abut the main display module, so that there is no splicing gap in the display screen; the upper and lower positions and the front and back positions between the adjacent screen bodies 10 are more accurately adjusted through the second wall-mounted component 30 of the present application, and the integrity and display effect of the spliced ​​screen are improved. In one embodiment, the screen fixing structure 81 includes a back panel, a support frame 812 and a middle frame 813. The support frame 812 is installed on the back panel, and the support frame 812 is used to support the optical film located between the main display module and the back panel. The middle frame 813 is installed on the support frame 812, and the middle frame 813 supports the edge area on the rear side of the main display module.

[0059] Referring to Figures 2 to 4 and 13 , the first wall-mounted assembly 20 includes a first support member 22 and a plurality of first hanging members 21. The first support member 22 is a wall-mounted plate extending in the left-right direction, and the plurality of first hanging members 21 are spaced apart in the left-right direction. The first support member 22 supports the plurality of first hanging members 21.

[0060] Among them, the first support member 22 is a wall-mounted plate extending in the left-right direction. On the one hand, the first wall-mounted component 20 plays the role of supporting the overall weight of the screen body 10. The first support member 22 is set as a long wall-mounted plate structure with a certain length. In this way, the first support member 22 can be fastened to the installation surface by multiple fasteners. The more firmly the first support member 22 is fixed to the installation surface, the greater the weight that the first support member 22 can support. The first support member 22 can support the heavy screen body 10 more reliably. On the other hand, the first support member 22 extends in the left-right direction and has a certain length. The first support member 22 can provide a left-right sliding track for the first hanging member 21 and the screen body 10, so that after the screen body 10 is hung by the first wall-mounted component 20, the screen body 10 can be pushed left-right to approach another screen body 10.

[0061] In addition, when the first support member 22 provides a track for the left-right movement of the first hanging member 21 and the screen body 10, the screen body 10 cooperates with the first support member 22 through multiple first hanging members 21 arranged at intervals. It can stably support the screen body 10 by supporting the screen body 10 in a dispersed manner at multiple positions, and at the same time reduce the weight and volume of the first hanging member 21, thereby reducing the load on the first support member 22. Referring to Figures 1 and 2, when first wall-mounted components 20 are provided on the rear sides of two adjacent screen bodies 10 in the left and right directions, multiple first hanging members 21 arranged at intervals are used in each first wall-mounted component 20, which can reduce the size of the first hanging member 21 in the left and right directions, and can avoid the first hanging members 21 in adjacent components from interfering with each other after the screen bodies 10 are close to each other and abut against each other on the left and right sides.

[0062] Referring to Figures 13 and 16 , the first support member 22 is provided with a plurality of fixing holes 2202, through which fasteners can be passed to secure the first support member 22 to the mounting surface. The plurality of fixing holes 2202 are spaced apart in the left-right direction, allowing the first support member 22 to be secured to the mounting surface via the plurality of fasteners, thereby enhancing the securing strength of the first support member 22. In one embodiment, the fixing holes 2202 are waist-shaped holes extending in the left-right direction. During installation, the installer is required to pre-drill the mounting holes in the wall. When attaching the first support member 22, the fasteners pass through the first support member 22 and into the wall mounting holes. The elongated waist-shaped fixing holes 2202 can accommodate certain drilling errors in the wall mounting holes, thus preventing the first support member 22 from being unable to be mounted on the wall due to drilling errors in the wall mounting holes. It is understood that even if the first support member 22 has a certain left-right error in its installation position on the wall due to some error in the position of the wall mounting holes, the screen 10 can be accurately aligned by subsequently adjusting the left-right or vertical position of the screen 10. In one embodiment, referring to Figures 15 and 16 , the first support member 22 is a wall-mounted plate. The length of the first support member 22 corresponds to the left-right direction of the spliced ​​screen, and the width of the first support member 22 corresponds to the up-down direction of the spliced ​​screen. The first support member 22 is provided with a plurality of fixing holes 2202 , with each pair of adjacent fixing holes 2202 spaced apart in the left-right direction and the up-down direction to stably secure the first support member 22 .

[0063] Continuing to refer to Figures 4, 7, 10 to 12, the rolling member 23 is rotatably mounted on the first hanging member 21, and the rolling member 23 abuts against the first support member 22. In one embodiment, in the first wall-mounted assembly 20, the first support member 22 is a long strip structure extending in the left-right direction and a plurality of first hanging members 21 are arranged at intervals. If the rolling member 23 is arranged on the long first support member 22, more rolling members 23 need to be arranged on the first support member 22 so that the first hanging member 21 contacts the rolling member 23 during the lateral movement. In this embodiment, however, the rolling member 23 is installed on the first hanging member 21, which can maintain rolling friction between each first hanging member 21 and the first support member 22 and reduce the number of rolling members 23 arranged.

[0064] 10 , at least two first rolling members 23 are arranged in each first hanging member 21 at intervals along the left-right direction, so as to improve the left-right sliding smoothness of the first hanging member 21 on the first support member 22 .

[0065] Referring to Figures 4 and 13 , the upper side of the first support member 22 serves as the support surface, and the first rolling member 23 abuts the support surface at the top of the first support member 22. In this way, the weight of the screen 10 is transferred to the support surface at the top of the first support member 22 via the first hanging member 21 and the first rolling member 23. When the screen 10 and the first hanging member 21 move in the left-right direction, the rolling member 23 located at the top of the first support member 22 effectively reduces the resistance to the left-right movement of the screen 10. In other embodiments, the rolling member 23 can also be located on the front or rear side of the first support member 22.

[0066] In other embodiments, the first wall-mounted assembly 20 may also include multiple first support members 22 and one first hanging member 21, wherein the first hanging member 21 is a wall-mounted plate extending in the left-right direction, and the multiple first support members 22 are spaced apart in the left-right direction, supporting the first hanging member 21. Alternatively, the first wall-mounted assembly 20 may include a single elongated first support member 22 and a single elongated first hanging member 21.

[0067] Please refer to Figure 28. Optionally, the first hanging member 21 includes a first mounting portion 201 and a first hanging portion 202 connected to each other, and the first mounting portion 201 is used to connect to the display screen; the first support member 22 includes a second mounting portion 203 and a first support portion 204 connected to each other, and the second mounting portion 203 is used to connect to the mounting surface.

[0068] In one embodiment, as shown in Figures 10 to 12 , for the first hanging member 21, the first mounting portion 201 is a fixing plate 211, and the first hanging portion 202 is a hanging plate 212. For the first supporting member 22, the second mounting portion 203 includes a back plate 221, an upper side plate 222, a lower side plate 223, an upper limit plate 224, and a lower limit plate 225.

[0069] The first mounting portion 202 and the first support portion 204 are inserted and engaged in the vertical direction. The first support portion 204 supports the first mounting portion 202 from bottom to top, so that the first support member 22 supports the first mounting member 21; the first mounting member 21 can move relative to the first mounting portion 21 in the left-right direction under the action of an external force. The first mounting portion 202 and the first support portion 204 are inserted and engaged in the vertical direction, which means that at least a portion of the first support portion 204 is located in front of and / or behind the first mounting portion 202. When the first mounting member and the screen 10 move synchronously left and right, the front and rear movement limits of the first mounting portion 202 can be limited by the first support portion 204. During the left-right movement of the screen 10, even if the operator slightly pushes the screen 10 away from the mounting surface, the platform can prevent the first mounting portion 202 from moving too far forward and thus separating from the first support portion 204. Compared with the solution in which the first support member 22 is completely arranged below the first hanging member 21 and the first support member 22 has no front and rear limiting effect on the first hanging member 21, this embodiment ensures that when the position of the screen body 10 is adjusted left and right, the first support part 204 always maintains support for the first hanging part 202 by inserting the first support part 204 and the first hanging part 202 up and down.

[0070] Optionally, the first mounting portion 201 and the first hanging portion 202 are arranged in the up-down direction, and the second mounting portion 203 and the first supporting portion 204 are arranged in the up-down direction. This makes it convenient for the operator to lock the first mounting portion 201 to the rear side of the screen body 10 from back to front, and to lock the second mounting portion 203 to the mounting surface from front to back using fasteners; the size of the first wall-mounted component 20 in the front-to-back direction is also controlled as much as possible to reduce the distance between the back side 15 of the screen body 10 and the mounting surface.

[0071] The first supporting portion 204 and the first hanging portion 202 can be inserted into each other in the vertical direction in at least two ways.

[0072] Method 1 for inserting the first supporting portion into the first hanging portion 202:

[0073] Referring to Figure 28, the first hanging part 202 is provided with a groove 2101, and the lower side of the first hanging part 202 is provided with a bottom groove connected to the groove 2101, and the first support part 204 is inserted into the groove 2101 through the bottom groove. When the first support part 204 is inserted into the groove 2101 of the first hanging part 202 from bottom to top, it can not only support the first hanging part 202 from bottom to top, but also cooperate with the groove walls on the front and rear sides of the groove 2101 of the first hanging part 202 to limit the forward and backward movement of the first hanging part 21, and prevent the first hanging part 21 from falling off while supporting the first hanging part 21. In this way, the groove 2101 of the first hanging part 202 integrates multiple functions such as left and right sliding guide, support, and limit, and has a simple structure.

[0074] Optionally, the left and right ends of the first hanging portion 202 form end notches connected to the groove 2101. In other words, the groove 2101 of the first hanging portion 202 is a left-right through structure, and the two ends of the first support portion 204 extend to the outside of the groove 2101 through the end notches respectively. In this way, the first hanging portion 202 can be allowed to move left and right on the first support portion 204 without restriction. In addition, when the left and right dimensions of the first support portion 204 are longer, the left and right dimensions of the first hanging portion 202 can be configured to be shorter, which can also meet the left and right movement stroke of the screen body 10 relative to the mounting surface and reduce the weight of the screen body 10 plus the first hanging member 21. On the other hand, it also avoids the left and right dimensions of the first hanging portion 202 being longer, thereby avoiding mutual interference and blocking by the first hanging portion 202 on the rear side of the adjacent screen body 10 when it moves left and right with the screen body 10. Of course, in other embodiments, the left and right ends of the first hanging portion 202 may also be closed without end notches, but the left and right dimensions of the first hanging portion 202 need to be set longer to provide a groove 2101 of a certain length so that the first hanging member 21 has the freedom to move left and right relative to the first support member 22.

[0075] Optionally, referring to Figures 11, 12, and 28, there is a front-to-back position adjustment margin between the first hanging member and the first support member. In this way, after the display screen is installed on the wall, the front-to-back position adjustment margin allows the operator to fine-tune the front-to-back position of the display screen and the first hanging member fixed to the display screen, so as to make the front-to-back segment difference between adjacent display screens smaller and flatter, and avoid the situation where one high and one low appear between the display surfaces 14 of adjacent display screens, so as to improve the display effect and writing effect. In one embodiment, the groove 2101 extends in the left-right direction, and the front and rear sides of the groove 2101 respectively have a front groove wall 21011 and a rear groove wall 21012. There is a fitting gap between the first support portion 204 and the front groove wall 21011 and / or a fitting gap between the first support portion 204 and the rear groove wall 21012. The fitting gap provides a front and rear adjustment margin. When the front and rear position of the screen body 10 needs to be adjusted, the screen body 10 moves forward and backward in a small range, driving the first hanging part to move forward and backward. Due to the existence of the fitting gap, the first hanging part 202 can move forward and backward in a small range relative to the first support portion 204 without being blocked by the first support portion 204 fixed to the mounting surface.

[0076] It can be understood that when there is no fitting gap between the first support portion 204 and the rear groove wall 21012 or the front groove wall 21011, the first hanging portion 202 is blocked by the first support portion 204, and the screen body 10 cannot be adjusted backward or forward. The position between the screen body 10 and the installation surface is fixed. At this time, if there is a front-to-back distance difference between the screen body 10 and the display surface 14 on the front side of the adjacent screen body 10, and there is a front-to-back step difference between the adjacent display surfaces 14, to adjust the front-to-back position of the screen body 10, it is necessary to remove the installed screen body 10, replace the first wall-mounted component 20 of another size, and then reinstall the screen body 10, so that the distance between the screen body 10 and the installation surface is increased or decreased to adjust the front-to-back step difference between the adjacent screen bodies 10. However, this adjustment method is cumbersome. In the first wall-mounted component 20 of this embodiment, a front-to-rear adjustment margin is reserved between the first supporting portion 204 and the first hanging portion 202, and a second wall-mounted component 30 for adjusting the front-to-rear position of the screen body 10 is also provided on the rear side of the screen body 10. After the screen body 10 is installed on the installation surface, the front-to-rear position of the screen body 10 can be adjusted without re-disassembling the screen body 10, and the adjustment is convenient and quick.

[0077] Second method of inserting the first supporting portion 204 into the first hanging portion:

[0078] The first supporting portion 204 is provided with a groove, and a top notch communicating with the groove is provided on the upper side of the first supporting portion 204 , and the first hanging portion 202 is inserted into the groove through the top notch.

[0079] Optionally, the front and rear sides of the groove respectively have a front groove wall and a rear groove wall, and a fitting clearance is provided between the first hanging portion 202 and the front groove wall and / or a fitting clearance is provided between the first hanging portion 202 and the rear groove wall. It is understood that the provision of the fitting clearance is mainly to provide margin for front-to-back position adjustment of the screen body 10 and the first hanging member 21.

[0080] Continuing with Figures 10 to 12 , in one embodiment, the groove 2101 is configured on the first mounting member 21 as follows: the first mounting member 21 includes a fixed plate 211 and a mounting plate 212, the first mounting portion 201 being the fixed plate 211, and the first mounting portion 202 being the mounting plate 212. The fixed plate 211 is used for assembly with the screen body 10, and the mounting plate 212 is used for assembly with the first support member 22. The fixed plate 211 is connected to the screen body 10 by fasteners, snap-fit ​​connections, welding, or other methods. The mounting plate 212 includes a first hanging plate 2121, a second hanging plate 2122 and a third hanging plate 2123. The first hanging plate 2121 is connected to the fixed plate 211, the second hanging plate 2122 is connected to the first hanging plate 2121 at an angle, and the third hanging plate 2123 is connected to the second hanging plate 2122 at an angle. A groove 2101 is formed between the first hanging plate 2121, the second hanging plate 2122 and the third hanging plate 2123.

[0081] 12 and 28 , the first support portion 204 is inserted into the groove 2101 of the mounting plate 212 , allowing the first mounting portion 202 to be mounted on the first support portion 204 . The first mounting plate 2121 and the third mounting plate 2123 are located on either side of the first support portion 204 in the front-to-back direction. After the first mounting portion 202 is mounted on the first support portion 204 , the front-to-back position of the first mounting portion 202 is restricted by the front first mounting plate 2121 and the rear third mounting plate 2123 , respectively. This prevents the first mounting portion 202 from falling off the first support portion 204 , ensuring reliable installation. The second mounting plate 2122 is located above the first supporting portion 204 , allowing the first supporting portion 204 to support the second mounting plate 2122 from bottom to top, thereby supporting the first mounting portion 202 and the screen body 10 .

[0082] In one embodiment, the fixing plate 211 and the mounting plate 212 of the first mounting member 21 are integrally formed. The first mounting member 21 is a structure formed by a bending process or a structure formed by injection molding.

[0083] In one embodiment, referring to Figures 12 and 28, the rear side of the first hanging plate 2121 and the front side of the first support member 22 are clearance-fitted in the front-to-back direction, and the rear side of the first support member 22 and the front side of the third hanging plate 2123 are clearance-fitted in the front-to-back direction. In this way, when the first hanging member 21 is hung on the first support member 22, the first hanging member 21 has the freedom to move forward or backward a certain distance relative to the first support member 22, that is, the screen body 10 has the freedom to move forward or backward a certain distance relative to the installation surface. In conjunction with Figures 3 and 12, after both screen bodies 10 are erected and hung on the installation surface, if the front-to-back positions of the two screen bodies 10 are misaligned, the front-to-back position of one of the screen bodies 10 can be adjusted. The clearance fit between the first hanging plate 2121 and the first support member 22, and the clearance fit between the third hanging plate 2123 and the first support member 22, ensures that the first support member 22 does not hinder the fine adjustment of the front-to-back distance between the first hanging member 21 and the screen body 10.

[0084] In one embodiment, referring to Figures 10 to 12, the first hanging member 21 further includes a horizontal plate 213, through which the fixing plate 211 is connected to the hanging plate 212. The fixing plate 211 is a vertical plate extending in the up-down direction. The fixing plate 211 can be attached to the back side of the screen body 10 to provide good support for the screen body 10 after the fixing plate 211 is fixed to the screen body 10. The horizontal plate 213 extends in the front-to-back direction to space the fixing plate 211 and the hanging plate 212 in the front-to-back direction, thereby ensuring a clearance fit between the fixing plate 211 and the first support member 22 in the front-to-back direction. In this way, even if the front-to-back position of the screen body 10 is slightly adjusted, the first support member 22 will not interfere with the fixing plate 211.

[0085] Referring to Figures 4, 7, 10 to 12, and 28, the rolling member 23 is rotatably mounted on the first hanging member 21. The first hanging member 21 is provided with a groove 2101, within which the rolling member 23 is positioned. The two ends of the rolling member 23 are rotatably mounted to the front and rear walls 21012 of the groove 2101. The groove 2101 provides a clear position for the installation of the rolling member 23. The position of the rolling member 23 can also be seen through the groove 2101, making installation of the rolling member 23 quick and easy. In this embodiment, the two ends of the rolling member 23 are rotatably mounted to the first hanging plate 2121 and the third hanging plate 2123, respectively. The rolling member 23 can rotate relative to the first hanging member 21, and the rotation axis of the rolling member 23 extends in the front-to-back direction. In this way, referring to Figure 28, the supporting surface at the top of the first support member 22 supports the rolling member 23. When the first hanging member 21 moves relative to the first support member 22 in the left and right directions, the rolling member 23 rotates around its rotation axis, and the rolling member 23 rolls on the top of the first support member 22, reducing the friction resistance of the first hanging member 21 moving left and right.

[0086] Continuing with Figure 11 , in one embodiment, the rolling member 23 includes a shaft portion 231 extending forward and backward, and cap portions 232 disposed at the front and rear ends of the shaft portion 231. The shaft portion 231 of the rolling member 23 passes through the first hanging plate 2121, the groove 2101, and the second hanging plate 2122. One cap portion 232 of the rolling member 23 is located on the side of the first hanging plate 2121 facing away from the third hanging plate 2123, and the other cap portion 232 of the rolling member 23 is located on the side of the third hanging plate 2123 facing away from the first hanging plate 2121. In this embodiment, the cap portions 232 at both ends of the intermediate shaft portion 231 enable the rolling member 23 to be rotatably mounted on the first hanging member 21. This allows for quick and easy installation of the rolling member 23, prevents it from becoming loose, and ensures smooth rotation.

[0087] Referring to Figure 28 , the first mounting portion protrudes upward and rearward relative to the first mounting portion 201, and the first support portion 204 protrudes upward and forward relative to the second mounting portion 203. This allows the second mounting portion 203 to be mounted to the mounting surface from front to back using fasteners, without the first support portion 204 obstructing the fastener's locking path. Furthermore, the first mounting portion 201 can be mounted to the back surface 15 of the screen 10 from back to front using fasteners, without the first mounting portion 202 obstructing the fastener's locking path. Furthermore, when the screen 10 drives the first mounting portion 202 to be mounted on the first support portion 204 from top to bottom, the first support portion 204 inserts from bottom to top into the groove 2101 of the first mounting portion 202, thereby supporting the first mounting portion 202 from bottom to top, facilitating the screen 10 to be reliably and movably mounted on the first support member 22. The first mounting portion 201 is located in front of the second mounting portion 203.

[0088] In other embodiments, the first hanging portion 202 may also be disposed on the lower side of the first mounting portion 201 , and the first supporting portion 204 may also be disposed on the lower side of the second mounting portion 203 .

[0089] 2 , 3 , and 7 , the first wall-mounted assembly 20 is disposed in the upper-middle or middle region of the rear surface 15 of the screen 10. For a screen 10 having the first wall-mounted assembly 20 disposed on the rear side, the first wall-mounted assembly 20 supports the weight of the screen 10. Placing the first wall-mounted assembly 20 in the upper-middle or middle region helps stabilize the screen 10 and prevent it from tipping over.

[0090] During the installation process, the screen body 10 is first hung on the first support member 22 through the first hanging member 21, and the first support member 22 is used to bear part of the weight of the screen body 10, so that the installer can adjust the left and right position of the screen body 10 more effortlessly. Therefore, the first wall-mounted component 20 is set in the upper middle area or the middle area, which can well support the screen body 10, making the adjustment of the left and right position of the screen body 10 more effortless and efficient. Please refer to Figure 7. The two side edges of the screen body 10 along the up and down direction (y direction) are the upper side edge 12 and the lower side edge 13 of the screen body 10. The distance between the upper side edge 12 and the lower side edge 13 is a, and the distance between the upper side edge 12 and the first hanging member 21 is b, b<a / 2, and the first wall-mounted component 20 is set in the upper middle area. In other embodiments, b=a / 2 and the first wall-mounted component 20 is set in the middle area.

[0091] Please refer to Figures 2, 3, and 8. The back surfaces 15 of two adjacent screen bodies 10 arranged in the left-right direction are both provided with first wall-mounted components 20. The first support members 22 in the two adjacent first wall-mounted components 20 are both wall-mounted panels with long strip structures extending in the left-right direction. In one embodiment, adjacent first support members 22 are connected by a connecting member 24. Each first support member 22 is used to cooperate with a screen body 10. During installation, the number of first support members 22 can be flexibly selected according to the number of screen bodies 10 to be spliced, making the assembly of the display screen more flexible. In other embodiments, adjacent first support members 22 are integrally formed.

[0092] The following describes the first wall-mounted assembly 20 by taking the example of connecting adjacent first support members 22 via a connector 24: The first wall-mounted assembly 20 further includes a connector 24 disposed between two adjacent first support members 22. The two ends of the connector 24 are respectively engaged with the first support members 22 on either side in a vertical direction (y-direction) for limiting position, and / or the two ends of the connector 24 are respectively engaged with the first support members 22 on either side in a front-to-back direction (z-direction) for limiting position, so that the vertical alignment and / or front-to-back alignment of the two adjacent first support members 22 are more accurate. As a result, after the two adjacent screens 10 are respectively hung on the two first support members 22, the vertical difference between the two adjacent screens 10 is smaller, the vertical alignment is more accurate, the front-to-back flatness of the two adjacent screens 10 is improved, and the front-to-back alignment is more accurate. This reduces the adjustment range required using the first adjustment member 33 and / or the second adjustment member 34, making on-site installation of the spliced ​​screen more convenient and time-saving.

[0093] For example, by first using the connector 24 to align and position two adjacent first support members 22, and then mounting the two screens 10, the front-to-back misalignment between adjacent screens 10, as shown in FIG20, and the top-to-bottom misalignment between screens 10, as shown in FIG21 and FIG22, can be avoided. FIG15(a) to FIG15(c) illustrate the assembly steps for installing the connector 24 between the two first support members 22.

[0094] It should be noted that the aforementioned position-limiting cooperation between the connecting member 24 and the first support member 22 is achieved by surface-to-surface contact. In other embodiments, the connecting member 24 and the first support members 22 at both ends may also be position-limited only in the vertical direction (y direction) or only in the front-to-back direction (z direction).

[0095] Please refer to Figures 12, 13, 15, and 16. In order to make the assembly between the first support member 22 and the connecting member 24 more convenient and quick, the first support member 22 and the connecting member 24 are plugged into each other. Specifically, the two ends of the connecting member 24 are plugged into the first support members 22 on the left and right sides respectively. During installation, the first first support member 22 is fixed to the wall, the first end of the connecting member 24 is plugged into the first first support member 22, and then the second first support member 22 is plugged into the second end of the connecting member 24, and then the second first support member 22 is fixed to the wall. Of course, during installation, the two first support members 22 can also be plugged into each other through the connecting member 24 to form an assembly, and then the first support member 22 is fixed to the wall. In this application, the first support member 22 and the connecting member 24 are assembled by plugging into each other on the left and right sides. The assembly process does not require particularly precise alignment, and the operation process is convenient and quick. 15( a ) to 15 ( c ), the connector 24 is inserted into the first support member 22 on the right side, and the first support member 22 on the left side is inserted into the connector 24 . Both operations can be performed from left to right. The two insertion directions are consistent, and the assembly efficiency is high.

[0096] In order to better align the relative positions of the two adjacent first support members 22 in advance, the first support members 22 on both sides are connected to the two ends of the connecting member 24 by fasteners. After the relative positions of the two adjacent first support members 22 in the vertical direction and the front-to-back direction are adjusted and aligned under the limitation of the connecting member 24, the first support members 22 and the connecting member 24 are locked by fasteners, locking the relative positions of the two adjacent first support members 22 in the x-direction, y-direction, and z-direction, thereby aligning the vertical positions and the front-to-back positions of the two screen bodies 10 hung on the first support members 22 on both sides as much as possible. Referring to Figures 12 and 16, the first support member 22 is provided with a first connecting hole 2201, and the connecting member 24 is provided with a second connecting hole 2401. Fasteners are inserted through the second connecting hole 2401 and the first connecting hole 2201 to achieve the locking and fixation of the connecting member 24 and the first support member 22.

[0097] In one embodiment, the first support member 22 is provided with a slot, and the connector 24 is inserted into the slot of the first support member 22 to achieve insertion and limited fit. The left or right end of the first support member 22 forms an end notch that communicates with the slot. The connector 24 is a connecting plate. The connector 24 can be inserted into the slot of the first support member 22 through the end notch, facilitating insertion from left to right or right to left, and achieving limited fit between the connector 24 and the first support member 22 in the vertical direction and in the front-to-back direction.

[0098] Referring to Figures 13 and 16 , the front side of the first support member 22 is further provided with a front notch (not labeled in the figures) that communicates with the slot. The front notch is used to expose at least a portion of the structure of the connector 24, making it easier to observe whether the connector 24 is properly positioned within the slot. The front notch also conveniently exposes the second connection hole 2401 on the connector 24 for fasteners such as screws to pass through, making it easier for the installer to use fasteners to lock the connector 24 to the first support member 22. The front notch can improve installation efficiency. The front side of the first support member 22 refers to the side of the first support member 22 that is away from the installation surface and closer to the screen body 10.

[0099] In one embodiment, referring to Figures 12, 14 and 16, the first support member 22 includes a back plate 221, an upper side plate 222, a lower side plate 223, an upper limit plate 224 and a lower limit plate 225, the upper limit plate 224 and the back plate 221, and the lower limit plate 225 and the back plate 221 are spaced apart in the front-to-back direction; the upper limit plate 224 and the lower limit plate 225 are spaced apart in the up-down direction, the upper limit plate 224 is connected to the back plate 221 through the upper side plate 222, and the lower limit plate 225 is connected to the back plate 221 through the lower side plate 223.

[0100] The back plate 221, the upper side plate 222, and the upper limit plate 224 define a first slot 2203, while the back plate 221, the lower side plate 223, and the lower limit plate 225 define a second slot 2204. The slot of the first support member 22 includes the first slot 2203 and the second slot 2204. The upper limit plate 224 and the lower limit plate 225 are spaced apart in the front-to-back direction to form a front notch of the slot. The ends of the connector 24 in the upper and lower directions are respectively inserted into the first slot 2203 and the second slot 2204. The rear side of the connector 24 abuts against the back plate 221, and the upper portion of the front side of the connector 24 abuts against the first limit plate, while the lower portion abuts against the second limit plate, thereby achieving a limited fit between the connector 24 and the first support member 22 in the front-to-back direction. The upper side surface of the connecting member 24 abuts against the upper side plate 222 , and the lower side surface of the connecting member 24 abuts against the lower side plate 223 , so as to achieve position-limiting cooperation between the connecting member 24 and the first supporting member 22 in the upper and lower directions.

[0101] Several configurations of the second wall-mounted component 30 in the spliced ​​screen are provided below.

[0102] Configuration method 1: A second wall-mounted assembly 30 is provided on the rear side of each screen 10. Furthermore, a first adjustment member 33 and a second adjustment member 34 are provided in the second wall-mounted assembly 30 on the rear side of each screen 10. Thus, the vertical position of the two screens 10 can be adjusted via the first adjustment member 33 on the rear side, and the front-to-back position of the two screens 10 can be adjusted via the second adjustment member 34 on the rear side. This provides more flexible adjustment, more efficient adjustment of the vertical alignment and front-to-back alignment between the two screens 10, and better reduction of the vertical and front-to-back gaps between the two screens 10.

[0103] Configuration mode 2: A second wall-mounted assembly 30 is provided on the rear side of each screen 10. Furthermore, of the two screens 10, all second wall-mounted assemblies 30 on the rear side of one screen 10 are provided with a first adjustment member 33, and all second wall-mounted assemblies 30 on the rear side of the other screen 10 are provided with a second adjustment member 34. Of the two screens 10, the vertical position of one screen 10 is adjustable, and the front-to-back position of the other screen 10 is adjustable.

[0104] Configuration mode three: among every two adjacent screen bodies 10 , only one screen body 10 is provided with a second wall-mounted component 30 on its rear side, and the second wall-mounted component 30 is provided with a first adjusting member 33 and a second adjusting member 34 .

[0105] For the screen 10 with a second wall-mounted assembly 30 on the rear side, the second wall-mounted assembly 30 can be installed at a corner of the screen 10 or in an area near the side edge of the screen 10. This not only facilitates the installer to operate and adjust the first adjustment member 33 or the second adjustment member 34, but also provides reliable support for the screen 10. The corner of the screen 10 is the location near the intersection of two adjacent outer edges of the screen 10.

[0106] In one embodiment, each screen 10 has four corners: an upper left corner 111, an upper right corner 112, a lower left corner 113, and a lower right corner 114. For example, the upper left corner 111 is located near the intersection of the left side of the screen and the upper side 13. The locations indicated by the dotted circles in Figures 21 to 23 are the locations of the four corners of the back surface 15 of the screen 10. In the splicing screen, for the screen body 10 with a second wall-mounted component 30 on the rear side, the second wall-mounted components 30 are all set at the four corners of the rear side of the screen body 10. Referring to Figures 2 and 3, the second wall-mounted components 30 are all set at the four corners of the screen body 10. On the first hand, the second wall-mounted components 30 with the function of adjusting the up and down position and the front and back position of the screen body 10 are arranged at the corners of the screen body 10, and the position of the adjustment member is close to the outer edge of the screen body 10, which is convenient for the installer to operate the first adjustment member 33 or the second adjustment member 34 from the side to achieve position adjustment; on the second hand, the four second wall-mounted components 30 not only support the four corners of the screen body 10 from bottom to top, so as to disperse and evenly bear the weight of the screen body 10 and improve the hanging stability of the screen body 10; on the third hand, after the position adjustment of the four corners is determined, the up and down position or the front and back position of the display surface 14 of the screen body 10 can be accurately adjusted, effectively avoiding the up and down position gap or the front and back segment difference between the screen bodies 10.

[0107] In one embodiment, in the second wall-mounted assembly 30, the first adjustment member 33 is less than 70 cm from at least one outer edge of the screen body 10, and the second adjustment member 34 is less than 70 cm from at least one outer edge of the screen body 10. This makes it easier for an operator to reach into the gap between the screen body 10 and the mounting surface to operate the adjustment member. Optionally, in the second wall-mounted assembly 30, the first adjustment member 33 is less than 30 cm, or less than 15 cm, or less than 8 cm from at least one outer edge of the screen body 10, and the second adjustment member 34 is less than 30 cm, or less than 15 cm, or less than 8 cm from at least one outer edge of the screen body 10. When the adjustment member is closer to the outer edge, it is easier for an operator to perform adjustment operations, such as rotating the adjustment member, by simply reaching a finger into the gap between the screen body 10 and the mounting surface. Furthermore, by adjusting the second hanging assembly 30 at the four corners, the position of the screen body 10 can be adjusted from the four corners simultaneously, making the overall position adjustment of the screen body 10 more precise.

[0108] Optionally, the four corners of the rear side of each screen body 10 are provided with a second wall-mounted component 30, and each set of the second wall-mounted components 30 includes a first adjustment member 33 and a second adjustment member 34. In other words, the up and down positions and the front and back positions of the four corners of each screen body 10 can be adjusted. In this way, the up and down positions and the front and back positions of the second hanging members 31 provided at the four corners of the back side 15 of each screen body 10 can be adjusted, and the adjustment operation is more convenient, flexible, and fast, and can adapt to more situations. When, as shown in Figure 21, the left screen body 10 is tilted to the left as a whole and the right screen body 10 is horizontal, the first adjustment members 33 at the four corners of the left screen body 10 can be used to adjust the left screen body 10 to a horizontal state as shown in Figure 24. In this way, the upper side edges 12 of the left and right screen bodies 10 are located in the same horizontal plane, and the left and right screen bodies 10 are aligned in the up and down directions to meet the requirements. When, as shown in FIG20 , one of the two screen bodies 10 tilts backward, the second adjustment members 34 at the four corners of the rear side of the tilted screen body 10 can be used to adjust the two screen bodies 10 to a state where the two display surfaces 14 are located in the same plane, thereby achieving zero-step difference fit between the two screen bodies 10.

[0109] In other embodiments, for the screen 10 having the second wall-mounted assembly 30 on the rear side, the second wall-mounted assembly 30 having the first adjustment member 33 can be respectively arranged near the left and right sides of the screen 10, and the second wall-mounted assembly 30 having the second adjustment member 34 can be respectively arranged near the upper side 12 and the lower side 13 of the screen 10. In this way, the vertical position of the left side of the screen 10 can be adjusted by the first adjustment member 33 arranged near the left side, and the vertical position of the right side of the screen 10 can be adjusted by the first adjustment member 33 arranged near the right side, thereby achieving efficient adjustment of the vertical position of the entire screen 10. For example, when the adjacent screens 10 are in the state of FIG21 , the vertical position of the left screen 10 is mainly adjusted by the first adjustment member 33 on the left side (not shown in the figure), so as to adjust the left screen 10 to an overall horizontal state, so that the left and right screens 10 tend to the state shown in FIG24 . The front and rear position of the upper side 12 of the screen body 10 can be adjusted by the second adjustment member 34 arranged near the upper side 12, and the front and rear position of the right side of the screen body 10 can be adjusted by the second adjustment member 34 arranged near the right side, thereby achieving efficient adjustment of the front and rear position of the entire screen body 10.

[0110] In other embodiments, the layout of the first wall-mounted assembly 20 and the second wall-mounted assembly 30 on the rear side of each screen 10 may also be as follows: the back side 15 of each screen 10 on the rear side of the screen 10 has an upper region and a lower region distributed along its vertical direction, wherein, as shown in FIG2 , the back side 15 of each screen 10 has a virtual transverse centerline 151, and the distance from the transverse centerline 151 to the upper side 12 of the screen 10 and the distance from the lower side 13 of the screen 10 are the same, the upper region is located above the transverse centerline 151, and the lower region is located below the transverse centerline 151. As shown in FIG7 , along the vertical direction of the screen 10, the size of the upper region is c, and the size of the lower region is d, where c=d. Optionally, the first wall-mounted component 20 is provided in the upper area, and at least two groups of second wall-mounted components 30 spaced apart along the left-right direction are provided in the lower area. In other words, the upper half of the screen body 10 is mounted on the mounting surface via the first wall-mounted component 20, and the lower half of the screen body 10 can be mounted on the mounting surface via the second wall-mounted component 30. In the case where the first support member 22 or the first hanging member 21 in the first wall-mounted component 20 is a long strip-shaped structure, the first wall-mounted component 20 provided at the top plays the main role in bearing the weight of the screen body 10, and the multiple second wall-mounted components 30 provided at the bottom can play the role of auxiliary bearing the weight of the screen body 10. At the same time, the multiple second wall-mounted components 30 provided at the bottom are spaced apart at least along the left-right direction, which can ensure that the front-back position or the up-down position of the screen body 10 can be adjusted at multiple positions distributed at the left and right sides, thereby ensuring a better front-back and up-down position adjustment effect of the screen body 10.

[0111] In other embodiments, multiple groups of second wall-mounted components 30 are arranged at intervals along the left-right direction on the upper and lower sides of the first wall-mounted component 20. The multiple groups of second wall-mounted components 30 can not only assist in supporting the screen body 10 from around the first wall-mounted component 20, but also adjust the front and rear positions and the up and down positions of the screen body 10 from multiple positions, and the position adjustment effect of the entire screen is good.

[0112] In one embodiment, a first adjusting member 33 is disposed between the second hanging member 31 and the second support member 32. The first adjusting member 33 extends in the vertical direction and may be, but is not limited to, a stud. Referring to Figures 3, 5, and 17 to 19, the first adjusting member 33 is threadedly connected to the second hanging member 31, with its end abutting against the second support member 32; or, referring to Figures 3, 6, and 9, the first adjusting member 33 is threadedly connected to the second support member 32, with its end abutting against the second hanging member 31. In one embodiment, when a second adjusting member 34 is disposed between the second hanging member 31 and the second support member 32, the second adjusting member 34 extends in the front-to-back direction and may be, but is not limited to, a stud. Referring to Figures 3, 5, 6, 9, and 17 to 19, the second adjusting member 34 is threadedly connected to the second hanging member 31, with its end abutting against the second support member 32; or, referring to Figures 3, 6, 9, and 17 to 19, the second adjusting member 34 is threadedly connected to the second support member 32, with its end abutting against the second hanging member 31 (not shown).

[0113] It can be understood that, between the second hanging member 31 and the second supporting member 32, one is threadedly connected to the first adjusting member 33 or the second adjusting member 34, and the other is against the first adjusting member 33 or the second adjusting member 34. In this way, by utilizing the thread engagement force and the mutual abutment force, when the first adjusting member 33 or the second adjusting member 34 is rotated, the second hanging member 31 can move up and down or forward and backward relative to the second supporting member 32.

[0114] Referring to Figures 17 to 19, in the second wall-mounted component 30, a first adjustment member 33 and a second adjustment member 34 are provided between the second hanging member 31 and the second support member 32. The second hanging member 31 includes a screen fixing portion 311, a second hanging portion 312 connected to the screen fixing portion 311, and a third mounting portion 313 connected to the screen fixing portion 311. The screen fixing portion 311 is used to connect and fix to the screen body 10, the second hanging portion 312 is connected to the upper side of the screen fixing portion 311, and the third mounting portion 313 is connected to the left or right side of the screen fixing portion 311. Referring to Figure 19, the second hanging portion 312 is located at the top of the second support member 32, the screen fixing portion 311 is provided on the front side of the second support member 32, and the third mounting portion 313 is located on the front side of the second support member 32. The second support member 32 includes a wall fixing portion 321 and a second support portion 322 connected to the wall fixing portion 321. The wall fixing portion 321 is used to be connected and fixed to the installation surface, and the second supporting portion 322 is connected to the front side of the wall fixing portion 321 .

[0115] Continuing with reference to Figures 17 to 19, the first adjusting member 33 is configured as follows: the first adjusting member 33 passes through the second hanging portion 312 of the second hanging member 31, the first adjusting member 33 is threadedly connected to the second hanging portion 312, and the end of the first adjusting member 33 abuts the second support portion 322 of the second support member 32; or the first adjusting member 33 passes through the second support portion 322 of the second support member 32, and the end of the first adjusting member 33 abuts the second hanging portion 312 of the second hanging member 31. Optionally, for the second wall-mounted assembly 30 disposed near the upper side 12 of the screen body 10, the first adjusting member 33 is threadedly connected to the second hanging portion 312, and the bottom of the first adjusting member 33 abuts the top of the second support member 32. In this way, the second support member 32 supports the second hanging member 31 by supporting the first adjusting member 33. At this time, the first adjusting member 33 can be adjusted from the top, making it easier for the installer to operate the first adjusting member 33 near the upper side of the screen body 10. Optionally, for the second wall-mounted component 30 arranged near the lower side 13 of the screen body 10, the first adjusting member 33 is threadedly connected to the second supporting member 32, and the top of the second adjusting member 34 abuts against the bottom of the second hanging part 312. In this way, the second hanging member 31 can be supported by the first adjusting member 33. At this time, the first adjusting member 33 can be adjusted from the bottom side, which is convenient for the installer to operate the first adjusting member 33 near the lower side of the screen body 10.

[0116] Continuing with Figures 17 to 19 , the second adjusting member 34 is configured as follows: the second adjusting member 34 passes through the third mounting portion 313 of the second hanging member 31 and is threadedly connected to the third mounting portion 313. The end of the second adjusting member 34 abuts against the second supporting portion 322 of the second supporting member 32. This allows the second adjusting member 34 to be adjusted within the gap between the screen body 10 and the mounting surface.

[0117] Continuing to refer to Figures 17 to 19, for the second hanging member 31, the third mounting portion 313 is disposed in the middle of the screen fixing portion 311, so that there is a certain gap between the front side of the third mounting portion 313 and the front side of the screen fixing portion 311. This gap provides an adjustment clearance space for the operator. The second adjusting member 34 is used to provide a portion for adjusting the operating position and is located in this gap. For example, the second adjusting member 34 is a bolt, and the screw head of the second adjusting member 34 is located in this gap. In this way, after the screen body 10 is installed on the mounting surface, it is convenient for the operator to insert an operating tool such as a wrench into the gap to rotate the second adjusting member 34, thereby rotating the adjusting member forward or backward to achieve front-to-back position adjustment of the second hanging member 31.

[0118] Referring to Figure 9 , after the left-right, up-down, and front-back relative positions of adjacent screens 10 are adjusted, the adjacent screens 10 are connected and relatively fixed via a first fixing member 40, thereby locking the two screens 10 together and preventing relative movement between the two screens 10 that could affect the display and user experience. Optionally, the first fixing member 40 extends in the left-right direction to span between the two adjacent screens 10.

[0119] Continuing with Figures 8 and 9, in the second hanging assembly disposed near the lower side 13 of the screen body 10, the second hanging member 31 and the second support member 32 are connected and relatively fixed by a second fixing member 50, thereby locking the relative position between the second hanging member 31 and the second support member 32. Referring to Figure 9, the second fixing member 50 extends in the front-to-back direction, and the second fixing member 50 is disposed horizontally between the screen body 10 and the mounting surface. The second fixing member 50 also serves to strengthen the support, preventing the lower side of the screen body 10 from tilting toward the mounting surface during use of the spliced ​​screen.
