[0041] Due to its excellent display effect and mature display control technology, the LED display screen has a high market acceptance and has been widely used. When the LED display screen is actually applied, a single display screen is a unit, and one or more LED modules are installed on each display screen. It is necessary to splice multiple display units to form a large display screen for display placement. Therefore, it is necessary to assemble and splice the display screen during application. With different display requirements, it may be necessary to perform planar splicing on the display screen to form a large planar display screen, or it may be necessary to perform 90° splicing on the display screen to form a large display screen with two or more vertical display surfaces. In order to ensure the display effect, it is necessary to minimize the splicing gap. In the related prior art, this is generally achieved by keeping the boxes of the display screen in mutual contact and using connecting pieces to connect and fix them. However, since most of the display screens are for rental business, they need to be frequently disassembled, transported, and transferred according to different placement sites. During this process, the box corners of the display screen are easily bumped and deformed, affecting the splicing operation and the final splicing effect.

[0042] The present utility model provides a display screen, which can solve the problem of the box corners being bumped and deformed during disassembly, transportation, and transfer.

[0043] Refer to Figures 1 to 9, a display screen according to an embodiment of the present utility model includes a box body 100, an LED module 200, and a corner guard assembly 300. One or more module installation positions are provided at the front end of the box body 100, which can be flexibly set according to requirements such as size. The LED module 200 is installed at the module installation position at the front end of the box body 100, and its quantity is set according to the quantity of the module installation positions. The corner guard assembly 300 includes a folding part 304 and a corner guard part 301. The corner guard part 301 has at least a first position and a second position. In the first position, the corner guard part 301 covers the outside of the top corner of the box body 100. In the second position, the corner guard part 301 is flush with the outer surface of the box body 100 or is concave with respect to the outer surface of the box body 100. The folding part 304 is rotatably connected between the corner guard part 301 and the box body 100, and is used to drive the corner guard part 301 to switch between the first position and the second position. Since the box body 100 generally has four corners, four corner guard assemblies 300 can be correspondingly provided, or according to experience, the corner guard assemblies 300 can be provided only at the corner positions that are easily bumped and deformed.

[0044] Referring to Figures 6 to 9 , it can be understood that the position of the corner guard part 301 in this embodiment is switched by the rotation of the folding part 304. When installing the display screen, only need to push the corner guard part 301 to the second position to perform normal assembly. When disassembling, switch the corner guard part 301 to the first position to protect the top corner of the box body 100 from being bumped and deformed during transportation, and solve the installation problem caused by corner deformation.

[0045] Referring to Figures 6 to 9 , in some embodiments of the present utility model, the folding part 304 is provided with a reset structure, and the reset structure is used to keep the folding part 304 in an unfolded state relative to the box body 100 and the corner guard part 301, so that the corner guard part 301 stably remains in the first position when not affected by external forces. In this embodiment, the reset structure is used to ensure that the folding part 304 is in an unfolded state when not affected by external forces, which is beneficial to the protection of the top corner of the box body 100 by the corner guard part 301. Under the action of the reset structure, the corner guard part 301 can ensure the stability of being in the top corner protection position of the box body 100, and avoid the situation that the corner guard part 301 is uncontrollably displaced and the top corner of the box body 100 is damaged by being bumped.

[0046] Referring to Figure 8 and Figure 9, in some embodiments of the present utility model, the corner guard assembly 300 further includes a locking portion 307. The locking portion 307 is used to abut against the corner guard portion 301 and / or the folding portion 304 when the corner guard portion 301 is in the second position, so as to restrict the corner guard portion 301 from switching to the first position. And the locking portion 307 can be separated from the folding portion 304 or the corner guard portion 301 under the action of an external force. Combining the foregoing analysis, the corner guard portion 301 will automatically rotate to the first position under the action of the reset structure when not subjected to an external force. However, during the assembly of the box body 100 and the working period after the assembly of the box body 100, the corner guard portion 301 needs to be stably maintained in the second position. In this embodiment, by providing the locking portion 307, the corner guard portion 301 is locked when it is in the second position, so as to overcome the acting force of the reset structure and ensure that the corner guard portion 301 is stably in the second position state, which is convenient for the disassembly and assembly operations of the box body 100. During actual assembly, the corner guard portion 301 is in the position of unfolding to protect the top corner of the box body 100. The staff manually pushes the corner guard portion 301 to rotate backward until it abuts against the locking portion 307 to complete the folding of the corner guard portion 301, and then the box body 100 is assembled. During actual disassembly, after the staff removes the box body 100, the locking portion 307 is adjusted to release the locking. The folding portion 304 and the corner guard portion 301 are unfolded under the action of the reset structure, and the corner guard portion 301 covers the top corner of the box body 100 again for protection.

[0047] Referring to Figures 6 to 9 , in some embodiments of the present utility model, the corner guard assembly 300 further includes a base plate 306, and the base plate 306 is fixed to the box body 100 by bolts. The folding portion 304 includes a folding member, one end of the folding member is rotatably connected to the base plate 306, and the other end of the folding member is rotatably connected to the corner guard portion 301. The reset structure includes a first reset member 305 and a second reset member 302. The first reset member 305 is disposed between the folding member and the base plate 306 and is used to keep the folding member unfolded relative to the base plate 306. The second reset member 302 is disposed between the folding member and the corner guard portion 301 and is used to keep the corner guard portion 301 unfolded relative to the folding member. In the folded state, the base plate 306, the folding member and the corner guard portion 301 are stacked in a Z shape. With the structural arrangement of this embodiment, when the folding portion 304 is unfolded relative to the base plate 306, the corner guard portion 301 can be moved outward and forward, and at the same time, the corner guard portion 301 is unfolded relative to the folding member and will protrude outward relative to the folding member, which can effectively cover the outside of the top corner of the box body 100 and avoid the influence of the folding member.

[0048] Referring to Figure 7 , in some embodiments of the present utility model, the folding member is provided with a relief opening 303, and the locking portion 307 passes through the relief opening 303 and abuts against the corner guard portion 301. This is beneficial to improving the structural integrity of the corner guard assembly 300 and reducing the installation space.

[0049] Reference Figure 8 and Figure 9 In some embodiments of the present invention, a platform 3011 is provided on the corner protector 301, protruding toward the position of the clearance opening 303. A snap-fitting recess 3012 is provided at one end of the platform 3011, which is away from the rotation center of the corner protector 301. The snap-fitting recess 3012 extends in a direction close to the rotation center of the corner protector 301. The locking portion 307 is provided with a lock 3071 that engages with the snap-fitting recess 3012. Furthermore, a matching guide structure is provided between the platform 3011 and the lock 3071. When the foldable member rotates from the unfolded state to the folded state, the guide structures between the platform 3011 and the lock 3071 interact, causing the lock 3071 to first avoid the platform 3011. When the snap-fitting recess 3012 aligns with the lock 3071, the lock 3071 snaps into the snap-fitting recess 3012. It is understandable that the avoidance of the lock buckle 3071 can be achieved by utilizing the elasticity of its own material, or the lock buckle 3071 can be set as a rotating structure or a movable structure.

[0050] In some embodiments of the present invention, the locking portion 307 is movable and adjustable, and the lock catch 3071 can be withdrawn from the engaging recess 3012 as the locking portion 307 moves. In this way, the locking portion 307 only needs to be pushed to move the lock catch 3071 out of the engaging recess 3012, and the corner protector 301 can be expanded to cover the top corner of the box body 100 under the action of the first and second restoring members 305 and 302.

[0051] Reference Figure 8 and Figure 9 In some embodiments of the present invention, the corner protector assembly 300 further includes a third reset member 308, which acts on the locking portion 307 to restrict movement of the locking portion 307 in the direction where the lock catch 3071 exits the engagement recess 3012. By providing the third reset member 308, this embodiment enables automatic reset of the locking portion 307. It is understood that the movement direction of the locking portion 307 can be flexibly adjusted as needed; it only needs to be able to move a certain distance to ensure smooth deployment of the corner protector 301.

[0052] Furthermore, considering that in the related prior art, LED display screens cannot meet the requirements of right-angle splicing and plane splicing at the same time, it is often necessary to produce LED display screens of two specifications. Figures 1 to 5, in some embodiments of the present utility model, the box body 100 includes multiple groups of splicing beams 101 arranged oppositely. On the outer side walls of two opposite splicing beams 101, 45° inclined surfaces 1011 are symmetrically arranged. Along the front end of the box body 100 towards the rear end direction of the box body 100, the inclined surfaces 1011 extend towards the center direction of the box body 100. With the structural arrangement of this embodiment, the splicing beam 101 can achieve 90° splicing by setting the 45° inclined surface 1011, and at the same time, it can also perform planar splicing by using the design of the connecting piece. Therefore, the above problems can be effectively solved and the cost can be reduced.

[0053] Referring to Figures 3 to 5 , in some embodiments of the present utility model, on the inclined surfaces 1011 of two opposite splicing beams 101, installation platforms 1012 are symmetrically recessed. And the display screen further includes a first splicing component and a second splicing component.

[0054] Referring to Figure 10 and Figure 11 , the first splicing component includes a first splicing seat 400 and a first splicing head 500. The first splicing seat 400 and the first splicing head 500 are structures that are matched and snap-connected to each other. The first splicing seat 400 and the first splicing head 500 can be detachably installed on two opposite installation platforms 1012 on both sides. And when installed on the installation platform 1012, the connection direction of the first splicing seat 400 is perpendicular to the connection direction of the first splicing head 500 for vertical splicing.

[0055] Referring to Figure 12 and Figure 13 , the second splicing component includes a second splicing seat 700 and a second splicing head 600. The second splicing seat 700 and the second splicing head 600 are structures that are matched and snap-connected to each other. The second splicing seat 700 and the second splicing head 600 can be detachably installed on two opposite installation platforms 1012 on both sides. And when installed on the installation platform 1012, the connection direction of the second splicing seat 700 is opposite to the connection direction of the second splicing head 600 for planar splicing.

[0056] Therefore, when the first splicing component is installed on the box body 100, vertical splicing can be performed between two box bodies 100. When the second splicing component is installed on the box body 100, planar splicing can be performed between two box bodies 100.

[0057] In summary, first, a 45° inclined surface 1011 is provided on the splicing beam 101 of the box body 100, so that there is no interference between the splicing beams 101 when the two box bodies 100 are spliced at 90°, providing a basis for compatible planar splicing and vertical splicing. Secondly, there are two types of splicing components. In the first splicing component, the splicing directions of the first splicing seat 400 and the first splicing head 500 are perpendicular to each other, so that the two box bodies 100 can be vertically spliced through the first splicing component. In the second splicing component, the splicing directions of the second splicing seat 700 and the second splicing head 600 are opposite, so that the two box bodies 100 can be planar spliced through the second splicing component. Furthermore, both the first splicing component and the second splicing component are installed on the box body 100 through the installation platform 1012. During application, the first splicing component or the second splicing component can be selected according to the splicing requirements, without reserving too much installation position and without affecting the strength of the box body 100. Therefore, the display screen of this embodiment can be vertically spliced and can also be planar spliced, solving the splicing problem in the prior art and being beneficial to reducing the equipment input cost.

[0058] Specifically, referring to Figure 5 and Figures 10 to 13 , in some embodiments of the present invention, a support portion 102 is provided on the installation platform 1012. The first splicing seat 400, the first splicing head 500, the second splicing seat 700, and the second splicing head 600 are all provided with installation portions 1001 matching the support portion 102 and are detachably connected to the support portion 102 through the installation portions 1001.

[0059] Referring to Figure 5 , in some embodiments of the present invention, since the installation platform 1012 is formed by the concave of the inclined surface 1011, the installation platform 1012 has two opposite platform side walls. In this embodiment, the support portion 102 protrudes on the two platform side walls, and the support portion 102 is located at one end of the platform side wall close to the center of the box body 100, so as to reserve enough space in the outer region of the support portion 102 for the installation and matching of the splicing components. Correspondingly, the two sides of the first splicing seat 400, the first splicing head 500, the second splicing seat 700, and the second splicing head 600 are all provided with installation portions 1001 to connect the support portions 102 on both sides.

[0060] In some embodiments of the present utility model, the support portion 102 is provided with a mounting hole and a positioning hole. The mounting portion 1001 is connected to the mounting hole by a screw, and the mounting portion 1001 is provided with a positioning protrusion that matches the positioning hole. The positioning protrusion can be a positioning post or a positioning ball plunger. With the structural arrangement of this embodiment, the quick disassembly and assembly of the mounting portion 1001 and the support portion 102 can be realized, which can not only ensure the mounting stability of the mounting portion 1001, and further ensure the mounting stability of the first splicing seat 400, the first splicing head 500, the second splicing seat 700, and the second splicing head 600, but also quickly disassemble the first splicing seat 400, the first splicing head 500, the second splicing seat 700, and the second splicing head 600 for replacement.

[0061] Referring Figure 10 and Figure 11 In some embodiments of the present utility model, the first splicing seat 400 is provided with a first splicing hole 402 and a first unlocking member 403. The first splicing hole 402 is arranged on the rear end face of the first splicing seat 400 along the direction from the rear to the front. The first unlocking member 403 penetrates into the first splicing hole 402 and can withdraw from the first splicing hole 402 under the action of an external force. The first splicing head 500 is provided with a first connecting shaft 502. The first connecting shaft 502 can be adjusted to move in the left - right or up - down direction. The shaft diameter of the first connecting shaft 502 is adapted to the first splicing hole 402 and can be inserted into the first splicing hole 402. And a first card slot 503 for the first unlocking member 403 to be inserted is arranged on the first connecting shaft 502. With the structural arrangement of this embodiment, when the first splicing seat 400 and the first splicing head 500 are installed on two opposite mounting platforms 1012, since the first connecting shaft 502 of the first splicing head 500 moves in the left - right or up - down direction, and the first splicing hole 402 is opened on the rear end face of the first splicing seat 400, when the first connecting shaft 502 on one box body 100 is inserted into the first splicing hole 402 on the other box body 100 between the two box bodies 100, the front end faces of the two box bodies 100 are perpendicular to each other, realizing a 90° splicing.

[0062] Specifically, the first unlocking member 403 is slidably installed on the first splicing seat 400. At the same time, a first spring is arranged between the first unlocking member 403 and the first splicing seat 400. Through the holding action of the first spring, one end of the first unlocking member 403 is located in the first splicing hole 402, and the other end extends to the side of the first splicing seat 400 close to the center of the box body 100. The end of the first connecting shaft 502 is provided with a taper, so that the first unlocking member 403 is automatically pushed away during insertion to complete the clamping. And during disassembly, only by pushing the end of the first unlocking member 403 outwards can the other end of it withdraw from the first splicing hole 402.

[0063] In some embodiments of the present utility model, the first splicing joint 500 is provided with a first locking assembly 504. The first locking assembly 504 can lock the first connecting shaft 502 to limit the movement of the first connecting shaft 502. In this way, after the first connecting shaft 502 is inserted into the first splicing hole 402 and the first locking member is snapped into the first card slot 503, the first connecting shaft 502 is locked by the first locking assembly 504 to prevent the first connecting shaft 502 from being uncontrollably withdrawn, which can improve the reliability of splicing. The first locking assembly 504 can be configured with the structures in related prior arts, as long as it can lock the first connecting shaft 502 and limit the movement of the first connecting shaft 502.

[0064] In some embodiments of the present utility model, the sizes of the first splicing base 400 and the first splicing joint 500 satisfy that when the first splicing base 400 is docked with the first splicing joint 500, the two opposite inclined surfaces 1011 on the two boxes 100 are in contact.

[0065] Refer to Figures 10 to 11 , in some embodiments, a first splicing surface 401 is provided at the rear end of the first splicing base 400. The first splicing surface 401 is perpendicular to the front-rear direction and parallel to the length direction of the splicing beam 101 where the first splicing base 400 is located. The first splicing hole 402 is opened on the first splicing surface 401. When installed on the installation platform 1012, the first splicing surface 401 is flush with the upper end of the platform side wall, and the outer side edge is flush with the outer side edge of the installation platform 1012 or retracted inward relative to the outer side edge of the installation platform 1012. A second splicing surface 501 is provided on the outer side (i.e., the side away from the center of the box 100) of the first splicing joint 500. The second splicing surface 501 is perpendicular to the front-rear direction and parallel to the length direction of the splicing beam 101 where it is located. The second splicing surface 501 is retracted inward relative to the outer side edge of the installation platform 1012, so as to form a space capable of accommodating the part of the first splicing base 400 protruding relative to the inclined surface 1011 between the second splicing surface 501 and the installation platform 1012. When the first splicing base 400 and the first splicing joint 500 are docked, the first splicing surface 401 and the second splicing surface 501 are in contact, and at the same time, the inclined surfaces 1011 of the two boxes 100 are in contact. The contact area is large, which is beneficial to improving the stability of splicing and can achieve seamless splicing between the two boxes 100.

[0066] Refer to Figure 12 and Figure 13, in some embodiments of the present utility model, the second splicing base 700 is provided with a third splicing surface 701, and the second splicing head 600 is provided with a fourth splicing surface 601. The third splicing surface 701 and the fourth splicing surface 601 are distributed along the front-back direction of the box body 100 and are parallel to the length direction of the splicing beam 101 where they are located. The third splicing surface 701 and the fourth splicing surface 601 are flush with the outer edge of the splicing beam 101 where they are located. In this way, when the second splicing base 700 and the second splicing head 600 are docked, planar splicing can be achieved through the abutting and fitting of the third splicing surface 701 and the fourth splicing surface 601, and a supporting force can be provided.

[0067] Refer to Figure 12 and Figure 13 , in some embodiments of the present utility model, the second splicing base 700 is provided with a second splicing hole 702 and a second unlocking member 703. The second splicing hole 702 is vertically arranged on the third splicing surface 701. The second unlocking member 703 penetrates into the second splicing hole 702 and can withdraw from the second splicing hole 702 under the action of an external force. The second splicing head 600 is provided with a second connecting shaft 602. The movement adjustment of the second connecting shaft 602 is parallel to the pore direction of the second splicing hole 702. The shaft diameter of the second connecting shaft 602 is adapted to the second splicing hole 702 and can be inserted into the second splicing hole 702. And the second connecting shaft 602 is provided with a second card slot 603 into which the second unlocking member 703 can be snapped. And further, the second splicing head 600 is also provided with a second locking component for locking the movement of the second connecting shaft 602, and the corresponding structural settings can all refer to the first splicing component for setting, which will not be elaborated here.

[0068] In some embodiments of the present utility model, the splicing beam 101 includes a first splicing beam 101 that is relatively upper and lower and a second splicing beam 101 that is relatively left and right. One of the first splicing component and the second splicing component is arranged on the first splicing beam 101, and the other is arranged on the second splicing beam 101. In this way, the box body 100 can be spliced flatly between left and right, vertically between up and down, or vertically between left and right, and flatly between up and down.

[0069] Refer to Figure 3 , two installation platforms 1012 are arranged on each splicing beam 101, so that there are two splicing components for connection and fixation between two adjacent box bodies 100.

[0070] In some embodiments of the present utility model, the box body 100 is further provided with a handle for carrying the display screen through the handle. Specifically, the handle is arranged in a way that can be separated from the box body 100, so as to be flexibly disassembled and assembled according to needs.

[0071] The separable design of the handle can be flexibly set. For example, it can be detachably connected to the box body 100, or the handle can be formed on the first splicing component and the second splicing component. Since the first splicing component and the second splicing component are detachably installed, the handle can be separated from the box body 100.

[0072] In some embodiments of the present utility model, the splicing beam 101 is provided with a magnetic attraction part on the inclined surface 1011. Since the splicing beam 101 in this embodiment is provided with the inclined surface 1011, it is not conducive for workers to use the already installed and fixed display screen as a fulcrum when assembling. In this embodiment, by setting the magnetic attraction part, the display screen can be placed on the already installed and fixed display screen and fixed through the magnetic attraction part for temporary fixation, reducing the labor intensity of workers.

[0073] Refer to Figure 4 , in some embodiments of the present utility model, the module installation position has a maintenance window 201 that is hollowed out front and back, and the maximum width dimension of the maintenance window 201 is sufficient for the LED module 200 to pass through. Specifically, the box body 100 is recessed at a pair of top corners corresponding to each module installation position for avoidance, thereby increasing the maximum width dimension of the maintenance window 201 and making it meet the requirement for the LED module 200 to pass through.

[0074] Moreover, the box body 100 is provided with a plurality of magnetic attraction parts at the module installation position, and at the same time, the LED module 200 is also provided with magnetic attraction parts, and is fixedly installed in the module installation position through magnetic attraction.

[0075] With the structural arrangement of this embodiment, the LED module 200 can be maintained from the front or the back, that is, it can be taken out from the rear of the box body 100, with stronger flexibility.

[0076] Refer to Figures 1 to 13 , in some embodiments of the present utility model, the display screen includes a box body 100, an LED module 200, a corner guard assembly 300, and a splicing assembly.

[0077] Specifically, the box body 100 is provided with four splicing beams 101 on the upper, lower, left and right sides. A bottom plate 1014 is arranged between the upper and lower splicing beams 101 for installing a power control box. A reinforcing rib 1015 is arranged between the left and right splicing beams 101, and four maintenance windows 201 are divided thereby. Moreover, the lower end of the bottom plate 1014 is recessed on the left and right sides to increase the diagonal distance of the two lower maintenance windows 201. Four module installation positions are arranged at the front end of the box body 100 corresponding to the four maintenance windows 201. Four LED modules 200 are provided and installed in the four module installation positions correspondingly. The size of the LED module 200 meets the requirement that it can pass through the two lower maintenance windows 201. The outer side walls of the four splicing beams 101 are symmetrically provided with inclined surfaces 1011 inclined at 45° from the outside to the inside, and four inclined corners are correspondingly formed. The box body 100 is recessed with a storage platform 1013 at the rear end of each of the four corners. Four corner protection components 300 are provided and installed on the four storage platforms 1013 correspondingly.

[0078] The corner protection component 300 includes a base plate 306, a folding part 304, a corner protection part 301, and a locking part 307. The base plate 306 is fixed to the bottom surface of the storage platform 1013 by screws. The folding part 304 is rotatably installed on the base plate 306, and a torsion spring is arranged between the folding part 304 and the base plate 306. The torsion spring is used to keep the folding part 304 open relative to the base plate 306 when no external force acts. The corner protection part 301 is rotatably installed at the end of the folding part 304, and a torsion spring is also arranged between the two, which is used to keep the corner protection part 301 open relative to the folding part 304 when no external force acts. Through the rotational connection, the folding part 304 and the corner protection part 301 can be folded and stored in the concave space formed by the storage platform 1013, avoiding protrusion and affecting the splicing of the box body 100. When unfolded, the opening direction is specifically as follows: the folding part 304 swings forward from the rear relative to the base plate 306, driving the corner protection part 301 to move from the rear to the outside of the corner of the box body 100. The locking part 307 is slidably installed on the box body 100, and a spring is arranged between the locking part 307 and the box body 100 for resetting, forming a pressing structure. A matching buckle structure is arranged between the end of the locking part 307 and the inner side of the corner protection part 301. By pressing the locking part 307, when the locking part 307 is forced to move against the spring action, the buckle structure is separated, and the corner protection part 301 can be automatically unfolded. When the corner protection part 301 is folded forcefully, the buckle structure can be used to limit the corner protection part 301.

[0079] Two installation platforms 1012 are arranged along the length direction of the splicing beam 101. The installation platforms 1012 are recessed from the inclined surface 1011. The two opposite installation platforms 1012 are used for installing splicing components to realize the splicing of the box body 100.

[0080] The splicing component includes a first splicing component and a second splicing component. The first splicing component includes a first splicing base 400 and a first splicing head 500. The first splicing base 400 and the first splicing head 500 are structures that are matched and snap-connected to each other. The first splicing base 400 and the first splicing head 500 can be detachably installed on two opposite installation platforms 1012 on both sides. And when installed on the installation platform 1012, the connection direction of the first splicing base 400 is perpendicular to the connection direction of the first splicing head 500. In this way, when splicing, it is necessary to keep the two boxes 100 perpendicular to each other to perform splicing, so as to achieve 90° splicing.

[0081] The second splicing component includes a second splicing base 700 and a second splicing head 600. The second splicing base 700 and the second splicing head 600 are structures that are matched and snap-connected to each other. The second splicing base 700 and the second splicing head 600 can be detachably installed on two opposite installation platforms 1012 on both sides. And when installed on the installation platform 1012, the connection direction of the second splicing base 700 is opposite to the connection direction of the second splicing head 600. In this way, the two boxes 100 can be spliced when they are flush with each other, that is, planar splicing is achieved.

[0082] Both the first splicing component and the second splicing component are provided with an installation structure consistent with the installation platform 1012, so as to achieve replacement and interchange.

[0083] In summary, the display screen in the present utility model has the following advantages:

[0084] 1. The box 100 has a 45° chamfer, which can meet planar splicing, 90° splicing and multi-sided magic cube splicing;

[0085] 2. By designing appropriate connecting pieces, it can be spliced with the display screens existing in the prior art;
