Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] In the field of stage equipment, stages with display functions have been applied to various performances and public events. A stage typically has at least a horizontally arranged display screen, with the display surface facing upwards, enabling the stage surface to display a variety of rich content and enhancing the stage's visual effects and interactivity. Existing stage displays are usually composed of multiple display modules spliced ​​together, with adjacent display modules connected by a connector to ensure relative stability between the modules.

[0003] Existing connectors can only withstand the horizontal tension between two adjacent display modules, and their ability to withstand vertical forces is weak. Furthermore, the connectors protrude from the back of the display modules; when the entire display screen is placed on a supporting surface, each connector directly contacts the surface, thus bearing the weight of the entire display screen and any personnel or materials it may support, making the connectors highly susceptible to damage. Currently, a transparent panel is installed on the stage for support, and the display screen is placed below this panel. The transparent panel then bears the weight of the display screen and any personnel or materials above it.

[0004] However, the addition of transparent panels inevitably increases the overall thickness of the stage, making it unsuitable for some applications where stage thickness is strictly limited. Furthermore, the transparent panels can cause refraction and reflection of the display light, potentially reducing the display's clarity, contrast, and brightness, thus affecting its overall display performance. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a display device to solve the problems of the current stage display screens being too thick and having poor display effects.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A display device includes a connecting component, an electrical box, and multiple display modules;

[0008] The back of the display module is provided with a first protrusion, and a first step is formed around the first protrusion. One end of the connecting component is connected to the first step of one of the display modules, and the other end of the connecting component is connected to the first step of the other display module.

[0009] A mounting groove is formed between the first protrusions of two adjacent display modules, and part or all of the electrical box is located in the mounting groove, and the electrical box is detachably connected to the first step or the first protrusion.

[0010] Preferably, a second boss is provided on the first boss, and a second step is formed around the second boss;

[0011] The connecting component has a first joining part and a second joining part that are adjacent and staggered. The first joining part is detachably connected to the first step, and the second joining part is detachably connected to the second step.

[0012] Preferably, the electrical box includes a first box body and a second box body, the first box body being connected to the first step, and the second box body overlapping the first box body;

[0013] The first housing has a first opening on the side away from the display module, exposing the interior of the first housing to the outside. The second housing has a second opening on the side away from the display module, exposing the interior of the second housing to the outside. Both the first opening and the second opening are filled with sealant.

[0014] Both the first box and the second box are located within the mounting groove.

[0015] Preferably, the electrical box includes a third box body, which overlaps the second box body;

[0016] The third housing has a third opening on the side opposite to the display module, which exposes the interior of the third housing to the outside, and the third opening is filled with the sealant.

[0017] Preferably, it also includes a base plate;

[0018] The multiple display modules are arranged in a matrix;

[0019] The second protrusion is provided with a connecting structure, which is detachably connected to the base plate, so that there is a gap between the second protrusion and the base plate.

[0020] Preferably, the two ends of the connecting component are respectively spliced ​​to two adjacent display modules, and the middle part of the connecting component is provided with a clearance groove, which is arranged opposite to the mounting groove so that the two form a clearance through hole;

[0021] The first housing and / or the second housing pass through the clearance through hole.

[0022] Preferably, the display module has a plurality of first water-permeable holes, which penetrate the front and back sides of the display module.

[0023] Preferably, the connecting component has a plurality of second water-permeable holes, which are oriented toward the display module.

[0024] Preferably, it further includes a first connecting strip, the first connecting strip having adjacent and mutually perpendicular first connecting surfaces and second connecting surfaces;

[0025] At least two of the adjacent display modules are arranged perpendicularly to each other, the first connecting surface is detachably connected to the first step of one of the display modules, and the second connecting surface is detachably connected to the first step of the other display module.

[0026] Preferably, the back edge of the display module is provided with a mounting bevel, and the angle between the mounting bevel and the back edge of the display module is less than or equal to 45°.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] The back of the display module is provided with a first protrusion, and a first step is formed around the back of the display module around the first protrusion. The two ends of the connecting component are respectively spliced ​​to the first step of the two adjacent display modules. The top surface of the first protrusion and the connecting component form a bearing plane. When the bearing plane is placed on the ground or other placement plane, the first protrusion and the connecting component jointly bear the pressure transmitted from the display module and above, which greatly improves the bearing performance of the display device. The mounting groove formed between the first protrusions of the two adjacent display modules is used to house the electrical box, so as to reduce or completely avoid the electrical box protruding from the bearing plane. The display device does not need to be provided with an additional transparent panel, which can reduce the thickness of the entire display device and improve the actual visible display effect of the display module.

[0050] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0051] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] Example 1

[0054] Combination Figures 1 to 16 As shown, the display device 1 of the present invention is schematically illustrated, including a connecting component 20, an electrical box 30, and a plurality of display modules 10.

[0055] Combination Figure 1 and Figure 2 Multiple display modules 10 are arranged in a matrix. The row direction of the multiple display modules 10 in the matrix is ​​denoted as the first direction X, the column direction of the multiple display modules 10 in the matrix is ​​denoted as the second direction Y, and the direction perpendicular to the display surface of the display module 10 is denoted as the third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0056] like Figure 5 The display module 10 has a front surface 10a and a back surface 10b. The front surface 10a of the display module 10 is the display surface. The back surface 10b of the display module 10 is provided with a first protrusion 11. A first step 13 is formed around the back surface 10b of the display module 10 around the first protrusion 11. The first protrusion 11 is located in the middle of the back surface 10b of the display module 10, so the first step 13 is square, annular, or other shapes. Figure 6 The display module 10 includes a face mask 18 and a base shell 19. The face mask 18 is made of a transparent material, such as transparent resin or glass. The base shell 19 has a cavity, within which is a lamp board 191 with several LED light-emitting units. The LED light-emitting units can be LED beads or LED light-emitting chips. When the face mask 18 is connected to the base shell 19, the light emitted by the LED light-emitting units passes through the face mask and is scattered to the outside. The front side 10a of the display module 10 is located on the face mask 18, and the back side 10b of the display module 10 is located on the base shell 19. One of the face mask 18 and the base shell 19 has a sealing rib 181, and the other has a sealing groove 192. The sealing rib 181 passes through the sealing groove 192, and the two fit together to prevent moisture from entering between the face mask 18 and the base shell 19, thereby protecting the lamp board 191 located between the face mask 18 and the base shell 19.

[0057] Specifically, such as Figure 4 and Figure 5The display module 10 has multiple first water-permeable holes 16, which penetrate the front 10a and back 10b of the display module 10. These first water-permeable holes 16 can be arranged in a matrix. The first water-permeable holes 16 are used for drainage, especially when the display device 1 is placed on a stage. Since the front 10a of the display module 10 is parallel to the horizontal plane, rainwater or water generated during stage atmosphere creation can flow from the front 10a to the back 10b of the display module 10 through the first water-permeable holes 16, preventing excessive water accumulation on the front 10a. The numerous first water-permeable holes 16 reduce the weight of the display module 10. Furthermore, because the axis of the first water-permeable holes 16 is perpendicular to the front 10a of the display module 10, the hole walls of the first water-permeable holes 16 can act as a support structure and bear the downward pressure on the display module 10 in the third direction Z, thereby improving the load-bearing capacity of the display module 10.

[0058] Combination Figure 3 , Figure 8 , Figure 10 and Figure 11 As shown, the connecting component 20 is used to connect two adjacent display modules 10. One end of the connecting component 20 is connected to the first step 13 of one of the display modules 10, and the other end of the connecting component 20 is connected to the first step 13 of the other display module 10. The connecting component 20 and the first step 13 can be connected by existing fasteners such as screws and bolts, or by existing interlocking structures. When the connecting component 20 and the first step 13 are joined together, the downward pressure from the display modules 10 and other personnel and materials above them forces the connecting component 20 and the first step 13 to fit tightly together. This structure ensures that the greater the downward pressure, the higher the connection stability between the connecting component 20 and the first step 13.

[0059] like Figure 8 A mounting groove 40 is formed between the first protrusions 11 of two adjacent display modules 10. Since multiple display modules 10 are arranged in a matrix, there are multiple mounting grooves 40. Some mounting grooves 40 extend along the first direction X, and some extend along the second direction Y. Part or all of the electrical box 30 is located within the mounting groove 40, and the electrical box 30 is detachably connected to the first step 13 or the first protrusion 11. The mounting groove 40 can not only accommodate the electrical box 30, reducing or completely preventing the electrical box 30 from protruding outwards from the bearing plane in the third direction Z, thereby reducing the overall thickness of the display device 1 (height in the third direction Z), but also accommodate the cables 80 connected to the electrical box 30 and the display modules 10, thus eliminating the need for additional cable channels on the back 10b of the display modules 10.

[0060] Combination Figures 9 to 11In order to avoid the electrical box 30 in the mounting groove 40, the size of the connecting component 20 also needs to be adapted. For example, two adjacent display modules 10 in the first direction X are connected by a connecting component 20. The electrical box 30 is provided in the mounting groove 40 between the first bosses 11 of the two display modules 10. The width of the connecting component 20 in the second direction Y should be adapted to reduce the width of the electrical box 30 in the second direction Y so as to leave more space for the electrical box 30.

[0061] Furthermore, a second boss 12 is provided on the first boss 11, such as... Figure 4 A second step 14 is formed on the top surface of the first protrusion 11 surrounding the second protrusion 12. The second protrusion 12 is located in the middle of the first protrusion 11, so the second step 14 is square-ring or other shapes. The projected area of ​​the first protrusion 11 and the second protrusion 12 on the back surface 10b of the display module 10 gradually decreases, which provides a structural basis for two adjacent display modules 10 to be arranged perpendicularly to each other and connected. The first protrusion 11 and the second protrusion 12 of one display module 10 and the first protrusion 11 and the second protrusion 12 of the other display module 10 form the aforementioned mounting groove 40. The arrangement of the second protrusion 12 makes the volume of the mounting groove 40 larger, and the mounting groove 40 can accommodate more cables 80 or a larger electrical box 30. The top surface of the second protrusion 12 is coplanar with the top surface of the connecting component 20, forming a bearing plane. When the display device 1 is placed on the ground or a placement plane, the bearing plane is in contact with the ground (or placement plane), that is, the top surface of the second protrusion 12 is in contact with the ground (or placement plane), and the top surface of the connecting component 20 is in contact with the ground (or placement plane). The downward pressure of the display module 10 itself and the personnel and materials above it is borne by the second protrusion 12 and the connecting component 20 together. This can significantly improve the bearing capacity of the display device 1, and the display device 1 with this structure does not need to be provided with an additional transparent panel for bearing, which can reduce the overall thickness of the display device 1 (height in the third direction Z).

[0062] Correspondingly, combined Figure 10 and Figure 11The connecting component 20 has adjacent and staggered first splicing parts 21 and second splicing parts 22. Both ends of the connecting component 20 have first splicing parts 21 and second splicing parts 22. The distance between the two first splicing parts 21 is smaller than the distance between the two second splicing parts 22. The two first splicing parts 21 are arranged opposite each other, and the two second splicing parts 22 are arranged back to back. The height of the first splicing part 21 in the third direction Z is greater than the height of the second splicing part 22 in the third direction Z. The first splicing part 21 is detachably connected to the first step 13, and the second splicing part 22 is detachably connected to the second step 14. The arrangement of the first splicing part 21 and the second splicing part 22 can increase the connection area between the connecting component 20 and the display module 10, reduce the pressure at the connection point between the connecting component 20 and the display module 10, and improve the load-bearing capacity of the display device 1 when the connecting component 20 and the display module 10 are made of the same material. Specifically, the end of the first splicing part 21 is connected to the first step 13, and the end of the second splicing part 22 is connected to the second step 14. The staggered arrangement of the ends of the first splicing part 21 and the second splicing part 22 can prevent the connecting member 20 from swaying relative to the display module 10. For example, two adjacent display modules 10 in the first direction X are connected by a connecting member 20. The arrangement of the first splicing part 21 and the second splicing part 22 can prevent the connecting member 20 from swaying relative to the display module 10 with the second direction Y as the axis of rotation, thereby improving the connection rigidity between the connecting member 20 and the display module 10 to a certain extent.

[0063] To improve the water permeability of the connecting component 20, the connecting component 20 is provided with a plurality of second water permeable holes 24. The second water permeable holes 24 are arranged facing the display module 10, that is, the hole axis of the second water permeable hole 24 is arranged along the third direction Z. Water that seeps into the gap between two adjacent display modules 10 and the first water permeable hole 16 of the display module 10 can be quickly discharged through the second water permeable holes 24, so as to prevent excessive water accumulation in the display device 1, which would increase the weight of the display device 1.

[0064] like Figures 12 to 16The electrical box 30 includes a first box 31, a second box 32, and a third box 33. The internal volume of the first box 31 is smaller than that of the second box 32, and the internal volume of the second box 32 is smaller than that of the third box 33. A first circuit board 312 is provided inside the first box 31, a second circuit board 322 is provided inside the second box 32, and a third circuit board 332 is provided inside the third box 33. A first terminal 15 electrically connected to the lamp board 191 is provided on the first step 13. A first pin 313 is provided on the side of the first box 31 facing the display module 10. The first box 31 is connected to the first step 13, and the first pin 313 is inserted into the first terminal 15. The first box 31 is located between the first steps 13 of two adjacent display modules 10 (i.e., within the mounting groove 40). In this embodiment, the first housing 31 is provided with four sets of first pins 313, each set of first pins 313 corresponding to one display module 10. Therefore, each first housing 31 can be connected to four display modules 10 and transmit power or control signals. The side of the first housing 31 facing away from the display module 10 is provided with a first opening 311 that exposes the interior of the first housing 31 to the outside. The first circuit board 312 is provided with a second terminal 3121 facing the first opening 311. The side of the second housing 32 facing the display module 10 is provided with a second pin 323. The second housing 32 overlaps the first housing 31 and the two are arranged perpendicularly. The second pin 323 is inserted into the second terminal 3121. Then, sealant can be injected into the first housing 31 through the first opening 311 to make the first housing 31 waterproof. The second housing 32 is located between the first steps 13 of two adjacent display modules 10 (i.e., within the mounting groove 40). In this embodiment, the second housing 32 is provided with two sets of second pins 323, and two sets of first pins 313 are respectively located at both ends of the second housing 32. Each set of second pins 323 corresponds to one first housing 31, so each second housing 32 can connect to two first housings 31. The side of the second housing 32 away from the display module 10 is provided with a second opening 321 that exposes the interior of the second housing 32 to the outside. The second circuit board 322 is provided with a third terminal 3221 facing the second opening 321. The third housing 33 is provided with two sets of third pins 333, and the two sets of third pins 333 are respectively located at both ends of the third housing 33. Each set of third pins 333 corresponds to one second housing 32, so each third housing 33 can connect to two second housings 32. The third pins 333 on the third housing 33 are inserted into the third terminal 3221. Sealant is injected into the second housing 32 through the second opening 321 to make the first housing 31 waterproof. The third box 33 overlaps the second box 32 and the two are arranged perpendicular to each other. Part or all of the third box 33 is located between the second protrusions 12 of two adjacent display modules 10. Sealant is injected into the third opening 331 of the third box 33 to make the third box 33 waterproof.The first box 31, the second box 32, and the third box 33 are stacked in the third direction Z, resembling a multi-layered terraced structure. During the assembly process, the structure is assembled according to the first box 31, the second box 32, and the third box 33, and the pins are welded to the corresponding terminals.

[0065] More specifically, the two ends of the connecting component 20 are respectively spliced ​​to two adjacent display modules 10. The middle part of the connecting component 20 is provided with a U-shaped clearance groove 23. The clearance groove 23 is arranged opposite to the mounting groove 40 so that the two form a clearance through hole 23a. The first box 31 and / or the second box 32 pass through the clearance through hole 23a. This allows the connecting component 20 to not only splice two adjacent display modules 10 and provide support force in the third direction Z, but also to limit the first box 31 and / or the second box 32. In addition, the cables 80 related to the display device 1 can also pass through the clearance through hole 23a to prevent the cables 80 from being tangled together without restriction.

[0066] Example 2

[0067] Combination Figure 3 and Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the display device 1 further includes a base plate 50, which is preferably a 3mm thick steel plate. A connecting structure 121 is provided on the second protrusion 12, which is detachably connected to the base plate 50, creating a gap between the second protrusion 12 and the base plate 50. An existing actuator (such as a hydraulic rod or electric actuator) forces the base plate 50 to bend and deform, causing the display modules 10 connected to the base plate 50 to move. This allows the display device 1 to switch between a flat screen (where the front faces 10a of multiple display modules 10 are on the same plane) and a curved screen (where the front faces 10a of multiple display modules 10 are on different screens). Simultaneously, the base plate 50 can also serve as a placement plane, connecting to each display module 10. The connection structure 121 creates a gap between the second protrusion 12 and the base plate 50, allowing each display module 10 to swing relative to the curved base plate 50, thus forming the aforementioned curved screen. Specifically, the connecting structure 121 is plate-shaped and has multiple mounting holes. Existing screws, bolts and other fasteners are passed through the mounting holes to connect the connecting structure 121, the second boss 12 and the base plate 50.

[0068] like Figure 8A gap 10c is provided between two adjacent display modules 10, allowing the two adjacent display modules 10 to swing relative to each other. Especially when the display device 1 switches to curved screen mode, the display modules 10 may encroach on the aforementioned gap 10c. In addition, the first splicing part 21 of the connecting component 20 is provided with a first connecting post 211, and the second splicing part 22 is provided with a second connecting post 223. Correspondingly, the first step 13 is provided with a first connecting hole 131, and the second step 14 is provided with a second connecting hole 141. The first connecting post 211 passes through the first connecting hole 131, and the second connecting post 223 passes through the second connecting hole 141. In this embodiment, the second splicing part 22 is provided with a receiving hole 221. The axis of the second connecting post 223 is collinear with the axis of the hole of the receiving hole 221, and the second connecting post 223 is located inside the receiving hole 221. The outer wall surface of the second connecting post 223 is connected to the inner wall surface of the receiving hole 221 through the connecting block 222. The connecting block 222 and the first connecting post 211 have deformation capability. For example, when subjected to a shear force of 50N, the first connecting post 211 can deform and swing relative to the first splicing part 21. The connecting block 222 deforms so that the second connecting post 223 can swing relative to the receiving hole 221. This structure can realize the swing of the display module 10 relative to the connecting component 20.

[0069] Example 3

[0070] Combination Figure 5 , Figures 17 to 20 As shown, the difference between this embodiment and embodiment 1 is that the display device 1 has at least two adjacent display modules 10 arranged perpendicularly to each other, at least one display module 10 is arranged horizontally and serves as the top surface of the stage, and at least one display module 10 is arranged vertically and serves as the side surface of the stage. Each surface of the stage can display images, improving the interactivity and aesthetics of the stage.

[0071] like Figure 19 and Figure 20 The display device 1 in this embodiment further includes a first connecting strip 60 and a second connecting strip 70. The first connecting strip 60 has adjacent and mutually perpendicular first connecting surfaces 61 and second connecting surfaces 62, and the second connecting strip 70 has adjacent and mutually perpendicular third connecting surfaces 71 and fourth connecting surfaces 72. In this embodiment, both the first connecting strip 60 and the second connecting strip 70 are strip-shaped cuboids, with both end faces of each connecting strip being squares and all four sides of each connecting strip being rectangles.

[0072] The first connecting surface 61 is detachably connected to the first step 13 of one of the display modules 10, and the second connecting surface 62 is detachably connected to the first step 13 of the other display module 10; simultaneously, the third connecting surface 71 is detachably connected to the second step 14 of one of the display modules 10, and the fourth connecting surface 72 is detachably connected to the second step 14 of the other display module 10. The first connecting strip 60 and the second connecting strip 70 can connect two adjacent and perpendicular display modules 10 and maintain the perpendicularity of the two display modules 10.

[0073] The display device 1 also includes a base frame, which can be welded from existing square tubing. The base frame is used to connect to the connecting structure 121 on the second boss 12 using existing fasteners such as screws and bolts, so that each display module 10 is connected to the base frame, which serves as the main load-bearing structure. The first connecting strip 60 and the second connecting strip 70 are used to reinforce two adjacent and perpendicularly arranged display modules 10. In the actual assembly process, multiple first connecting strips 60 and multiple second connecting strips 70 can be provided between two adjacent and perpendicularly arranged display modules 10.

[0074] In addition, such as Figure 5 The back surface 10b of the display module 10 is provided with a mounting bevel 17. The angle between the mounting bevel 17 and the back surface 10b of the display module 10 is less than or equal to 45°. When two adjacent and perpendicular display modules 10 are spliced ​​together, the mounting bevel 17 can avoid structural interference.

[0075] In summary, the back surface 10b of the display module 10 is provided with a first protrusion 11, and the back surface 10b of the display module 10 around the first protrusion 11 forms a first step 13. The two ends of the connecting component 20 are respectively spliced ​​to the first step 13 of two adjacent display modules 10. The top surface of the first protrusion 11 and the connecting component 20 form a bearing plane. When the bearing plane is placed on the ground or other placement plane, the first protrusion 11 and the connecting component 20 jointly bear the pressure transmitted from the display module 10 and above, which greatly improves the bearing performance of the display device 1. The mounting groove 40 formed between the first protrusions 11 of two adjacent display modules 10 is used to house the electrical box 30, so as to reduce or completely avoid the electrical box 30 protruding from the bearing plane. The display device 1 does not need to be provided with an additional transparent panel, which can reduce the thickness of the entire display device 1 and improve the actual visible display effect of the display module 10.

[0076] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
