Description
Technical Field
[0001] This invention relates to the field of flexible LED display module technology, specifically to an LED display module that is anti-crosstalk and flexible for splicing adaptation. Background Technology
[0002] Flexible LED display modules utilize flexible substrates and ultra-thin packaging technology, breaking the limitations of traditional rigid screens and possessing characteristics such as bendability, rollability, and lightweight design. The modules are equipped with high-density Mini / MicroLED chips, resulting in uniform color, high contrast, wide viewing angles, and clear, detailed display effects. Their thin overall thickness and low weight make them highly adaptable to various unconventional substrates such as curved walls, cylinders, and irregular shapes.
[0003] Existing flexible module splicing structures are rudimentary in design, often employing rigid butt joint fixing methods. These structures cannot adapt to deformation stress under curved surface bending and multi-module splicing conditions, easily leading to splicing gaps, module warping, pixel misalignment, and even cracking and damage. Their flexibility and structural stability are insufficient. In addition, traditional flexible modules lack dedicated dustproof and ventilation structures on the back. After long-term operation, dust and lint easily accumulate on the mounting surface and inside the frame cavity. This dust accumulation not only causes module bulging and flatness failure but also blocks heat dissipation space, resulting in heat buildup in the module and FPC circuitry, causing light decay and color shift. Summary of the Invention
[0004] The purpose of this invention is to provide a flexible, cross-linking LED display module that is resistant to light crosstalk and adaptable to various splicing methods, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a flexible LED display module with anti-crosstalk and splicing adaptability, comprising a flexible module body and an adhesive strip. The bottom of the flexible module body is provided with FPC circuitry, and the adhesive strip is installed on the outer surface of the FPC circuitry. A dust removal component for assisting dust removal is provided on the outside of the adhesive strip. The dust removal component includes suction holes, a corrugated connecting tube, an extension tube, an internal tube, and a dustproof backplate. Suction holes are equidistantly opened inside the dustproof backplate, and a corrugated connecting tube is installed in the middle of one end of the dustproof backplate. An internal tube is fixedly installed inside the corrugated connecting tube, and an extension tube is installed on the side of the dustproof backplate away from the corrugated connecting tube.
[0006] Furthermore, the dustproof back panel has a central hole structure inside and is rectangular in shape.
[0007] Furthermore, a connecting component for fixing the dustproof back panel is installed at the bottom of the dustproof back panel, and the connecting component includes a Velcro tab and a Velcro tab, with a Velcro tab installed on one side of the Velcro tab.
[0008] Furthermore, a flexible module LED light-emitting layer is installed on the top outer surface of the flexible module body, and a honeycomb light-shielding grid is provided on the outer surface of the flexible module LED light-emitting layer.
[0009] Furthermore, the outer surface of the honeycomb light-shielding grille is equipped with an AG anti-glare layer, and the bottom outer surface of the flexible module body is provided with magnetic suction columns.
[0010] Furthermore, the magnetic columns are evenly distributed along the rectangular path, and a flexible auxiliary strip is provided on the bottom outer surface of the flexible module body near the magnetic columns.
[0011] Furthermore, the flexible auxiliary strip has a "W" shaped cross-section and is symmetrically distributed about the center of the flexible module body.
[0012] Furthermore, the extension tube and the built-in tube are assembled by nesting and snapping, so that the dust removal components of adjacent multiple modules are interconnected to form a through airflow channel.
[0013] Furthermore, the adhesive strip covers the outside of the FPC circuit to form an annular sealed isolation structure, physically separating the front light-emitting area of the module from the back dust removal air duct area.
[0014] This invention provides a flexible, crosstalk-resistant LED display module with the following advantages: 1. This invention sequentially sets a honeycomb light-shielding grid and an AG anti-glare layer on the outer side of the flexible module LED light-emitting layer. The honeycomb light-shielding grid can form an independent physical light-shielding cavity for each LED pixel, completely blocking lateral stray light crosstalk and diffuse light leakage between pixels, greatly improving screen contrast and image purity, and eliminating problems such as blurry images and mixed colors. In conjunction with the AG anti-glare layer, the specular reflection is converted into soft diffuse reflection, effectively weakening the reflection of strong ambient light and the glare of direct human eye viewing, achieving a high-definition eye-protecting display effect. In addition, the dustproof back panel is quickly assembled to the equipment frame through the adhesive of Velcro and Velcro, which is convenient for disassembly and assembly, greatly reducing the difficulty of later equipment inspection and structural maintenance.
[0015] 2. This invention features an independently configured dust removal component for each module. Adjacent modules are fixed by nesting and engaging with the internal tubes via extension tubes, forming a continuous airflow channel. Combined with the evenly distributed suction holes on the dustproof backplate, the invention can thoroughly clean the dust and lint from the back cavity and mounting surface of the module using the negative pressure suction principle. This avoids problems such as module bulging, uneven force on the magnetic columns, and circuit oxidation caused by dust accumulation. The negative pressure airflow can simultaneously remove the heat generated by the flexible module body and FPC circuitry, achieving continuous dynamic ventilation and heat dissipation. This effectively reduces the module's operating temperature and eliminates faults such as high-temperature light decay, color shift, and magnetic demagnetization. No manual disassembly and maintenance are required, significantly reducing operation and maintenance costs. Attached Figure Description

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0019] like Figures 1-5As shown, a flexible LED display module with anti-crosstalk and splicing adaptability includes a flexible module body 1, a honeycomb light-shielding grille 2, an AG anti-glare layer 3, a flexible module LED light-emitting layer 4, a flexible auxiliary strip 5, a magnetic column 6, an adhesive strip 7, an FPC circuit 8, a connecting component 9, a Velcro 901, a Velcro 902, a dust removal component 10, a suction hole 1001, a corrugated connecting tube 1002, an extension tube 1003, an internal tube 1004, and a dustproof backplate 1005. The bottom of the flexible module body 1 is provided with an FPC... PC circuit 8, and adhesive strip 7 is installed on the outer surface of FPC circuit 8. A dust removal assembly 10 for auxiliary dust removal is provided on the outside of adhesive strip 7. The dust removal assembly 10 includes suction holes 1001, corrugated connecting pipe 1002, extension pipe 1003, internal pipe 1004, and dustproof backplate 1005. Suction holes 1001 are equidistantly arranged inside the dustproof backplate 1005, and a corrugated connecting pipe 1002 is installed at the middle of one end of the dustproof backplate 1005. An internal pipe is fixedly installed inside the corrugated connecting pipe 1002. 1004. An extension tube 1003 is installed on the side of the dustproof backplate 1005 away from the corrugated connecting pipe 1002. The interior of the dustproof backplate 1005 has a central hole structure and is rectangular. An adhesive strip 7 is fitted on the outside of the FPC circuit 8 at the bottom of the flexible module body 1 to form a ring-shaped sealed isolation structure, which completely physically isolates the display area of the LED light-emitting layer 4 of the front flexible module from the electrical connection area of the FPC circuit 8 on the back and the air duct area of the dust removal component 10, thus preventing the dust removal component from being blocked. During operation, the airflow and dust are prevented from entering the front-facing light-emitting area, ensuring a clean display surface free from light interference. Simultaneously, the electrical areas and the dust removal chamber operate independently, without interference. Each display module is independently equipped with a dust removal component 10, which includes a suction hole 1001, a corrugated connecting pipe 1002, an extension pipe 1003, an internal pipe 1004, and a dustproof backplate 1005. The inner side of the rectangular, perforated dustproof backplate 1005 forms a sealed dust removal and heat dissipation cavity with the back of the flexible module body 1. This structure employs a multi-module docking design, utilizing the corrugated connecting pipe 1002, extension pipe 1003, and internal pipe 1004 of adjacent modules for assembly. Precise fixation is achieved through the nested engagement of the extension pipe 1003 and the internal pipe 1004, ensuring interconnection of multiple dust removal pipes and forming a complete, continuous airflow channel. This guarantees unobstructed airflow in multi-module splicing scenarios.The suction holes 1001 evenly spaced inside the dustproof backplate 1005 serve as uniform dust collection and ventilation channels. During operation, an external fan generates negative pressure suction, which is uniformly conducted through the overall airflow channel composed of the interlocking extension tube 1003, corrugated connecting tube 1002, and internal tube 1004, ultimately acting on all the suction holes 1001 of the dustproof backplate 1005. Utilizing the principle of full-area negative pressure suction, on the one hand, it continuously adsorbs the floating dust, lint, and dust accumulation on the mounting surface of the module back, avoiding problems such as module bulging, poor heat dissipation, uneven force on the magnetic column 6, and dust accumulation and oxidation of the FPC circuit 8 caused by dust accumulation. On the other hand, through the continuous flow of negative pressure airflow, it can quickly remove the heat accumulated by the flexible module body 1 and the FPC circuit 8 during operation, achieving dynamic ventilation and heat dissipation, effectively reducing the overall operating temperature of the module, and avoiding faults such as light decay, color shift, high-temperature demagnetization, and circuit aging caused by high temperature. The corrugated connecting pipe 1002 has flexible deformation capability, which can be adapted synchronously with the bending and deformation of the flexible module body 1, ensuring that the air duct is sealed without air leakage in the curved screen state, and that dust cleaning and heat dissipation are uniform and without dead corners throughout the entire area, adapting to all flexible bending and multi-module splicing conditions.
[0020] like Figure 1 , Figure 2 and Figure 4As shown, a connecting component 9 for fixing the dustproof back panel 1005 is installed at the bottom. The connecting component 9 includes a Velcro 901 and a Velcro 902. The Velcro 902 is installed on one side of the Velcro 901. The bottom of the dustproof back panel 1005 is equipped with the connecting component 9, which consists of the Velcro 901 and the Velcro 902. Through the adhesive cooperation of the Velcro 901 and the Velcro 902, the dustproof back panel 1005 can be quickly attached and installed on the equipment frame, realizing quick disassembly and positioning, which is convenient for later air duct inspection and structural maintenance. The top outer surface of the flexible module body 1 is equipped with a flexible module LED light-emitting layer 4, and the outer surface of the flexible module LED light-emitting layer 4 is provided with a honeycomb light-shielding grille 2. The outer surface of the honeycomb light-shielding grille 2 is equipped with an AG anti-glare layer 3. The bottom outer surface of the flexible module body 1 is provided with magnetic pillars 6. The magnetic pillars 6 are arranged around rectangular paths, etc. The flexible module body 1 has a flexible auxiliary strip 5 on the bottom outer surface near the magnetic column 6. The cross-section of the flexible auxiliary strip 5 is W-shaped and symmetrically distributed about the center of the flexible module body 1. The magnetic columns 6 are evenly distributed at the bottom of the flexible module body 1. The module can be quickly aligned and installed by magnetic adsorption. It is easy to install and remove and is suitable for curved bending scenarios. The W-shaped flexible auxiliary strip 5 is symmetrically arranged at the bottom of the flexible module body 1. Utilizing its flexible deformation characteristics, it can adaptively buffer deformation stress during multi-module splicing and screen bending, offset splicing gap errors and bending tension stress, avoid module warping, cracking, and pixel misalignment, and greatly improve the overall splicing flatness and structural fatigue resistance. The flexible module body 1 is equipped with a flexible module LED light-emitting layer 4 as an imaging light source. The independent signal and power supply control of each pixel is realized through FPC circuit 8 to ensure accurate output of image color and brightness. A honeycomb light-shielding grid 2 and an AG anti-glare layer 3 are stacked sequentially on the outer side of the light-emitting layer. The honeycomb light-shielding grid 2 uses a honeycomb-shaped independent light-transmitting hole structure to physically shield and isolate the individual LED pixels of the flexible module LED light-emitting layer 4, effectively blocking stray light diffusion and lateral light crosstalk between adjacent pixels, completely eliminating problems such as blurry images, color mixing, and edge light leakage, and significantly improving screen contrast and image purity. The outer AG anti-glare layer 3 converts specular reflection into uniform diffuse reflection, weakens the reflection of strong ambient light and the glare of direct human eye viewing, reduces visual fatigue, and achieves a high-definition and soft display effect.
[0021] In summary, this anti-crosstalk and flexible splicing design is compatible with LED display modules, firstly based on... Figures 1-5The structure shown illustrates that, in use, the flexible module body 1 houses a flexible module LED light-emitting layer 4 as the imaging light source. Independent signal and power supply control for each pixel is achieved through FPC circuitry 8, ensuring accurate color and brightness output. A honeycomb light-shielding grille 2 and an AG anti-glare layer 3 are stacked sequentially on the outer side of the light-emitting layer. The honeycomb light-shielding grille 2 utilizes a honeycomb-shaped independent light-transmitting hole structure to physically shield and isolate the individual LED pixels of the flexible module LED light-emitting layer 4, effectively blocking stray light diffusion and lateral cross-lighting between adjacent pixels, completely eliminating problems such as blurry images, color mixing, and edge light leakage, significantly improving screen contrast and image purity. The outer AG anti-glare layer 3 converts specular reflection into uniform diffuse reflection, weakening ambient light reflection and direct eye glare, reducing visual fatigue, and achieving high contrast. The display effect is clear and smooth. Magnetic pillars 6 are evenly distributed at the bottom of the flexible module body 1, enabling quick alignment and installation of the module via magnetic adsorption. This facilitates easy assembly and disassembly and is suitable for curved surfaces. Symmetrically arranged W-shaped flexible auxiliary strips 5 at the bottom of the flexible module body 1 utilize their flexible deformation characteristics to adaptively buffer deformation stress during multi-module splicing and screen bending, offsetting splicing gap errors and bending tension stress. This prevents module warping, cracking, and pixel misalignment, significantly improving overall splicing flatness and structural fatigue resistance. The dustproof backplate 1005 is equipped with... The connecting component 9, composed of a hook and loop fastener 901 and a hook and loop fastener 902, allows the dustproof backplate 1005 to be quickly attached and installed on the equipment frame through the adhesive bonding of the hook and loop fastener 901 and the hook and loop fastener 902. This enables quick assembly and disassembly, facilitating subsequent air duct inspection and structural maintenance. An adhesive strip 7 is fitted around the FPC circuit 8 at the bottom of the flexible module body 1, forming a ring-shaped sealed isolation structure that connects the display area of the front flexible module LED light-emitting layer 4 with the electrical connection area of the back FPC circuit 8 and the air duct area of the dust removal component 10. Complete physical isolation prevents airflow and dust from entering the front light-emitting area during the operation of the dust removal component 10, ensuring a clean display surface free from light interference. Simultaneously, it allows for independent operation of the electrical areas and the dust removal cavity, ensuring no interference. Each display module is independently equipped with a dust removal component 10, which includes a suction hole 1001, a corrugated connecting pipe 1002, an extension pipe 1003, an internal pipe 1004, and a dustproof backplate 1005.
