Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to an LED holographic display device that is easy to install and maintain. Background Technology

[0002] Currently, video wall display technology is widely used in commercial advertising, stage performances, command and control, and other scenarios. It primarily achieves large-size screen displays by physically splicing multiple LED or LCD screens. The mainstream solution uses metal or plastic frames to fix the individual screen units, assembled with latches or magnetic structures. However, these traditional video wall displays have significant drawbacks: First, the thick frames result in noticeable gaps between the panels, disrupting the overall image integrity, especially when displaying cross-screen content, creating a visual disjointedness. Second, the complex connection structure between modules requires specialized tools for installation, and maintenance often necessitates complete screen disassembly, leading to inefficiency. Furthermore, existing video wall displays lack sufficient corner protection, making the display units susceptible to damage during transportation and installation, increasing operating costs. These shortcomings severely limit the effectiveness of video wall displays in demanding scenarios. Utility Model Content

[0003] The main purpose of this invention is to provide an LED holographic display device that is easy to install and maintain, enabling the rapid installation and fixation of multiple displays and facilitating maintenance.

[0004] To achieve the above objectives, this utility model proposes an LED holographic display device that is easy to install and maintain, comprising:

[0005] The display assembly includes multiple displays and a connecting structure. Each display has a display surface and a bottom surface. The connecting structure is disposed on the bottom surface of the display and connects the multiple display surfaces sequentially.

[0006] An edge-binding assembly includes multiple edge-binding strips, one side of which has a fixing groove, and the edge of the display component is inserted into the fixing groove.

[0007] In one possible implementation, the connection structure includes a plurality of fixing plates and a connecting cable. The plurality of fixing plates are respectively disposed on the bottom surface of each of the display screens, and at least one mounting groove is formed between the fixing plates and the display screens. The mounting grooves on the plurality of display screens together constitute an installation channel, and the connecting cable passes through the installation channel.

[0008] In one possible implementation, the edge-binding assembly further includes corner protectors that cover the edge strips at the corners of the display assembly.

[0009] In one possible implementation, the corner protector has a notch corresponding to the display surface of the display screen.

[0010] In one possible implementation, the edging strip has a sloping surface on the side away from the display component.

[0011] In one possible implementation, a reinforcing rib is connected to the back of the slope.

[0012] This utility model's technical solution employs multiple displays connected by a bottom-mounted structure, supporting flexible expansion to meet different size requirements. The edge-binding assembly securely fixes the display edges with edge strips featuring fixing grooves, while corner protectors further reinforce the corners, ensuring overall structural stability. Simultaneously, its notch design prevents obstruction of the display screen, guaranteeing the complete presentation of holographic images. The beveled design on the outer side of the edge strip not only enhances safety by preventing sharp-angle impacts but also optimizes the visual appeal, making the display appear thinner and more modern. Reinforcing ribs on the back enhance impact and deformation resistance, making it particularly suitable for large-size screens or high-load scenarios. The entire display device balances aesthetics and functionality; installation requires only plugging and fixing, and damaged modules can be replaced individually during maintenance, significantly reducing operating costs.

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Reference Figures 1 to 4 This utility model proposes an LED holographic display device that is easy to install and maintain, including a display component and an edge-binding component. The display component includes multiple display screens 1 and a connecting structure 2. The display screens 1 have a display surface 11 and a bottom surface 12. The connecting structure 2 is disposed on the display screens 1 and connects the multiple display screens 1 in sequence. The edge-binding component includes multiple edge-binding strips 3. One side of the edge-binding strip 3 is provided with a fixing groove 31, and the edge of the display component is inserted into the fixing groove 31.

[0023] Understandably, the display assembly includes multiple display screens 1 and a connecting structure 2. Each display screen 1 has a display surface 11 and a bottom surface 12 for displaying images. The connecting structure 2 connects the bottom surfaces 12 of the multiple display screens 1 sequentially to form a complete display assembly. This design facilitates modular assembly and disassembly.

[0024] The edge-binding assembly includes multiple edge-binding strips 3 for fixing and protecting the display components. Each edge-binding strip 3 has a fixing groove 31 on its side, allowing the edge of the display component to be directly inserted into the fixing groove 31 for quick installation and stable fixation. Multiple displays 1 are spliced ​​together to form a display component via a connecting structure 2. The edges of the display components are inserted into the fixing grooves 31 of the edge-binding strips 3, and the overall structure is fixed by the edge-binding strips 3.

[0025] The above design facilitates installation, as the modular design of the display screen 1, which allows for individual connection, and the insertion method of the fixing slot 31 simplifies the assembly process. It also facilitates maintenance; if a section of the display screen 1 is damaged, it can be disassembled and replaced individually without disassembling the entire device. Furthermore, the structure is stable, with the edge banding 3 serving both a fixing function and protecting the edges of the display screen 1. This design is suitable for building large LED holographic display screens 1, balancing flexibility, durability, and ease of maintenance.

[0026] Reference Figures 2 to 4 In one embodiment of the present invention, the connecting structure 2 includes a plurality of fixing pieces 21 and a connecting cable 22. The plurality of fixing pieces 21 are respectively disposed on the bottom surface 12 of each display screen 1. At least one mounting groove 4 is formed between the fixing pieces 21 and the display screen 1. The mounting grooves 4 on the plurality of display screens 1 are jointly configured to form an installation channel. The connecting cable 22 passes through the installation channel.

[0027] Understandably, the fixing piece 21 is fixed to the bottom surface 12 of each display screen 1. The bottom surface 12 of the fixing piece 21, which is in contact with the display screen 1, has at least one groove or channel, forming a mounting groove 4. After the mounting grooves 4 of all the display screens 1 are aligned, they together form a continuous mounting channel. The connecting cable 22 is a flexible rope, such as a metal cable or high-strength fiber, that runs through the entire mounting channel, connecting all the display screens 1 in series, maintaining the linkage and rollability of the overall structure. When all the display screens 1 bend or unfold synchronously, they will pull or roll up the connecting cable 22. Through the above settings, it is ensured that the screens are seamlessly spliced ​​when unfolded and tightly folded when rolled up; the fixing piece 21 and the connecting cable 22 of the connecting structure 2 provide mechanical strength to achieve stable rolling.

[0028] Reference Figures 1 to 2 In one embodiment of the present invention, the edge-binding component further includes corner protectors 5, which cover the edge-binding strips 3 at the corners of the display component.

[0029] Understandably, the corner protector 5 serves to cover the edge banding strip 3 at the corners of the display component, making the overall structure more stable and aesthetically pleasing, and providing additional protection. At the corners of the display component, the corner protector 5 covers the ends of the adjacent edge banding strip 3 to prevent the edge banding strip 3 from loosening or falling off, thus enhancing structural stability. The corner protector 5 can be made of sturdy materials, such as metal or high-strength plastic, making the corners more impact-resistant and preventing deformation due to collisions. The corner protector 5 can also conceal the seams of the edge banding strip 3, making the display screen 1 look cleaner and more integrated.

[0030] The corner protector 5 can be installed in two ways: a covering installation, where the corner protector 5 is directly fitted onto the end of the adjacent edge banding strip 3 and fixed by screws, clips, or adhesive; or a plug-in installation, where the corner protector 5 has a slot that directly engages with the end of the edge banding strip 3. In this example, the plug-in installation is preferred.

[0031] Since the corners are the most vulnerable parts of the display screen 1, the corner protectors 5 can provide effective protection; the modular design means that even if the edge strips 3 or corner protectors 5 are replaced, the entire display screen 1 does not need to be disassembled; if the display screen 1 adopts an irregular design such as arc or polygon, the corner protectors 5 can be customized to match different angles.

[0032] Reference Figure 1 In one embodiment of this utility model, the corner protector 5 has a notch 51 corresponding to the display surface 11 of the display screen 1.

[0033] Understandably, to ensure that the display effect of the display surface 11 is not affected, the corner protector 5 has a notch 51 at the position corresponding to the display surface 11 of the display screen 1. This prevents the corner protector 5 from obstructing the display screen while still providing corner fixation and protection. The notch 51 partially avoids the visible area of ​​the display screen 1, ensuring the complete display of the holographic image without visual obstruction. Although the corner protector 5 has a notch 51, it can still firmly fix the adjacent edge strip 3, ensuring overall stability.

[0034] Reference Figure 1 In one embodiment of the present invention, the edging strip 3 has a sloping surface 32 on the side away from the display component.

[0035] Understandably, the sloping surface 32 is located on the outer side of the edge strip 3, away from the display component, and has a sloping or curved transition rather than a right-angle structure. This improves safety by avoiding the sharp edges of traditional right-angle edge strips 3, reducing the risk of bumps and knocks, making it suitable for high-traffic areas such as shopping malls and stages. It also optimizes the visual effect; the sloping design reduces the visual thickness of the edge strip 3, making the display screen 1 appear thinner and more modern. Furthermore, it enhances ambient light adaptability; the sloping surface reduces the reflection of outer light onto the display surface 11, reducing glare interference, which is especially crucial for holographic display effects. When the display screen 1 is placed on the ground, the sloping structure prevents dust or rainwater accumulation, facilitating cleaning and maintenance.

[0036] Reference Figures 2 to 4 In one embodiment of this utility model, a reinforcing rib 33 is connected to the back of the slope surface 32.

[0037] Understandably, the reinforcing rib 33 is located on the back of the slope surface 32 and has a longitudinal protruding structure. Alternatively, it can also be a grid-like protruding structure. The reinforcing rib 33 significantly improves the bending resistance of the edge strip 3, prevents deformation of the large-size display screen 1 during assembly, enhances the load-bearing capacity of the overall structure, and is suitable for scenarios such as floor tile screens that can be stepped on. It can also disperse some of the external impact force and protect the internal connection structure 2.

[0038] This utility model's technical solution employs multiple display screens 1 connected by a bottom surface 12 and a connecting structure 2, supporting flexible expansion to meet different size requirements. The edge-binding assembly securely fixes the edges of the display screens 1 with edge-binding strips 3 featuring fixing grooves 31, while corner protectors 5 further reinforce the corners, ensuring overall structural stability. Simultaneously, the notch 51 design prevents obstruction of the display screen, ensuring the complete presentation of the holographic image. The beveled surface 32 on the outer side of the edge-binding strip 3 not only enhances safety by preventing sharp-angle impacts but also optimizes the visual appeal, making the display screens 1 appear thinner and more modern. The back reinforcing ribs 33 enhance impact and deformation resistance, making it particularly suitable for large-size screens or high-load scenarios. The entire display device balances aesthetics and functionality; installation requires only plugging and fixing, and damaged modules can be replaced individually during maintenance, significantly reducing operating costs.
