[0001] This utility model relates to the field of display screen technology, and in particular to an LED splicing display screen. Background Technology

[0002] Display screens are widely used in outdoor advertising, subtitles, and stage background effects due to their high luminous efficiency, long lifespan, safety, reliability, and energy efficiency. Since these applications typically require large display screens, it's necessary to splice different screens together. Existing splicing methods are relatively simple, using magnets or screws to join two screens, resulting in poor splicing and positioning, often leading to gaps and misalignment between screens. Utility Model Content

[0003] The main purpose of this utility model is to provide an LED splicing display screen that achieves seamless splicing and high-precision alignment, good positioning effect, and convenient and quick splicing.

[0004] To achieve the above objectives, this utility model proposes an LED splicing display screen, comprising:

[0005] Multiple support plates, each support plate having a front and a back, the front being covered with a display screen, and the back being provided with a splicing strip protruding from its edge. The splicing strips of any two support plates can be fitted together and abutted against each other. A fixing surface is formed on the side of the splicing strip away from the back, and a plurality of first fixing holes are provided on the fixing surface.

[0006] The fixing piece can be attached to the fixing surface of multiple abutting splicing strips, and the surface of the fixing piece is provided with a second fixing hole corresponding to the first fixing hole on the multiple fixing surfaces.

[0007] In one possible implementation, the edge of the fixing piece is detachably connected to a plurality of first supports.

[0008] In one possible implementation, the back of the support plate is further provided with a receiving chamber, the receiving chamber forming a receiving cavity, and the receiving chamber is provided with a cover.

[0009] In one possible implementation, a control motherboard and a second support member are disposed within the accommodating cavity.

[0010] In one possible implementation, the splicing strip has multiple weight-reducing holes on its surface.

[0011] In one possible implementation, the first support member includes a connecting screw and a support head, the connecting screw fixing the support head to the edge of the fixing plate.

[0012] This utility model's technical solution achieves seamless splicing and high-precision alignment by quickly locking the splicing strips on the back of the support plate with fixing plates. Combined with a detachable first support component, it can adapt to various installation scenarios such as wall mounting and floor stands, ensuring the stability of the large screen. The control motherboard and second support component are integrated within the cavity on the back of the support plate, along with an openable cover, enabling centralized management and rapid maintenance of power supplies, signal lines, and core components, reducing downtime. Weight-reducing holes on the surface of the splicing strips reduce overall weight while aiding airflow and heat dissipation, and also conceal wiring, balancing practicality and industrial aesthetics. The modular design allows for scaling up or down the screen as needed, with the cavity reserving upgrade space. Combined with standardized splicing components, it significantly reduces transportation, installation, and subsequent maintenance costs. Attached Figure Description

[0019] 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.

[0020] Reference Figures 1 to 2This utility model proposes an LED splicing display screen, including multiple support plates 1 and multiple fixing pieces 4. The support plates 1 have a front and a back. The front is covered with a display screen 2, and the back edge is provided with splicing strips 3. The splicing strips 3 of any two support plates 1 can be attached to each other. A fixing surface 31 is formed on the side of the splicing strip 3 away from the back. A plurality of first fixing holes 32 are opened on the fixing surface 31. The fixing pieces 4 can be attached to the fixing surfaces 31 of the multiple splicing strips 3 that abut against each other, and the surface of the fixing pieces 4 is provided with second fixing holes 41 corresponding to the first fixing holes 32 on the multiple fixing surfaces 31.

[0021] Understandably, the support plate 1 has a front and a back. The front is fitted with an LED display screen 2, while the back edge has raised splicing strips 3. The splicing strips 3 of two or more support plates 1 can be fitted together to splice multiple displays. The end face of the splicing strip 3 away from the back is a fixing surface 31, which has several first fixing holes 32 for connecting fixing pieces 4. The fixing pieces 4 can cover the fixing surfaces 31 of multiple splicing strips 3 that have been joined together. Furthermore, the fixing pieces 4 also have second fixing holes 41 corresponding to the positions of each first fixing hole 32 to ensure that the holes are aligned.

[0022] The display screen is assembled as follows: after the splicing strips 3 of the two support plates 1 are joined together, their fixing surfaces 31 are covered with fixing pieces 4. By aligning the first fixing hole 32 and the second fixing hole 41, screws or bolts are used to fix them, thereby firmly connecting the multiple support plates 1.

[0023] Reference Figures 1 to 2 In one embodiment of this utility model, the edge of the fixing piece 4 is detachably connected to a plurality of first support members 5.

[0024] Understandably, the outer edge of the fixing piece 4 is detachably connected to the first support member 5 (e.g., by screws, clips, magnets, etc.) for easy installation, adjustment, or replacement. The first support member 5 is a component that assists in fixing or enhancing structural stability, such as a support leg or bracket, used to fix the display screen to a wall or frame, or to provide support when placed on the ground. In addition, the first support member 5 may also be a hook or bolt, which can be directly fixed to the wall or connected to a column to form an independent support structure.

[0025] Reference Figures 1 to 2 In one embodiment of the present invention, a receiving chamber 6 is also provided on the back of the support plate 1, the receiving chamber 6 forms a receiving cavity inside, and a cover 61 is provided on the receiving chamber 6.

[0026] Understandably, the housing 6 is located on the back of the support plate 1. The back edge of the support plate 1 has splicing strips 3 for modular splicing, and the housing 6 is located in the center of the back between the splicing strips 3, without interfering with the splicing function. The interior of the housing 6 is a hollow structure used to store specific components, such as power supplies, control modules, and cables. The housing 6 is equipped with an openable cover for easy maintenance or replacement of internal components. The cover 61 can prevent dust and moisture from entering the housing cavity, extending the life of internal components; at the same time, it facilitates maintenance, allowing for inspection or replacement of components without disassembling the entire display screen.

[0027] Reference Figures 1 to 2 In one embodiment of this utility model, a control motherboard 62 and a second support member 63 are provided in the accommodating cavity.

[0028] Understandably, the control motherboard 62 is the control center of the LED display screen, responsible for receiving video signals, processing data such as color correction and refresh rate control, and distributing signals to the LED screens on the front of each support plate 1. The control motherboard 62, as a core component, is housed within a recessed cavity, avoiding exposed cables and improving aesthetics and safety. The cavity can be designed with ventilation holes or heat sinks in conjunction with the cover 61 to optimize motherboard heat dissipation. Furthermore, the motherboard can be quickly inspected or replaced by opening the cover 61, making maintenance convenient. The second support member 63 is fixed within the cavity and can be a metal bracket, plastic block, or other structure. Its function is to provide physical support for the support plate 1. When the display screen is used as floor tiles, the second support member 63 can provide support for the support plate 1, preventing the screen from deforming under external forces.

[0029] Reference Figures 1 to 2 In one embodiment of this utility model, the splicing strip 3 has a plurality of weight-reducing holes 33 on its surface.

[0030] Understandably, creating multiple holes in the splicing strip 3 reduces the overall weight of the support plate 1, making the display screen lighter and easier to transport and install. A well-designed weight-reducing hole 33 can reduce material usage and optimize costs without affecting the structural strength of the splicing strip 3. These holes are located on the side of the splicing strip 3 but do not affect its docking function or the installation of the fixing piece 4. Besides reducing weight, the weight-reducing hole 33 also increases airflow, aiding in heat dissipation for the LED display screen; some cables (such as power lines and signal lines) can be concealed through the weight-reducing hole 33, maintaining neatness; some weight-reducing holes 33 can be designed as auxiliary positioning holes for temporary alignment and fixation during splicing.

[0031] Reference Figures 1 to 2 In one embodiment of the present invention, the first support member 5 includes a connecting screw 51 and a support head 52, and the connecting screw 51 fixes the support head 52 to the edge of the fixing piece 4.

[0032] Understandably, the connecting screw 51 acts as a fastener, used to fix the support head 52 to the edge of the fixing plate 4. It directly contacts external support structures such as walls and brackets, providing support or suspension functions. It can be designed as a spherical, flat washer, or hook-shaped structure to adapt to different installation requirements. The connecting screw 51 is detachable, facilitating adjustment of the support head 52's position or replacement of the support type, such as changing a short screw to a longer one. Tightening the screw's threads prevents the support head 52 from loosening, ensuring the overall stability of the large screen after splicing.

[0033] This utility model's technical solution achieves seamless splicing and high-precision alignment by quickly locking the splicing strip 3 on the back of the support plate 1 with fixing pieces 4. Combined with the detachable first support component 5, it can adapt to various installation scenarios such as wall mounting and floor stands, ensuring the stability of the large screen. The control motherboard 62 and the second support component 63 are integrated within the accommodating cavity on the back of the support plate 1, along with the openable cover 61, enabling centralized management and rapid maintenance of power, signal lines, and core components, reducing downtime. The weight-reducing holes 33 on the surface of the splicing strip 3 reduce overall weight while aiding airflow and heat dissipation, and also conceal wiring, balancing practicality and industrial aesthetics. The modular design supports increasing or decreasing the screen size as needed, with the accommodating cavity reserving upgrade space. Combined with standardized splicing components, it significantly reduces transportation, installation, and subsequent maintenance costs.
