Description

Technical Field

[0001] This utility model relates to the technical field of LED display screen equipment, and in particular to a holographic transparent display module and display device. Background Technology

[0002] LED holographic transparent display modules are a new type of display technology developed on the basis of traditional LED displays. Through special structural design (such as hollowing, transparent substrate, high light transmittance LED beads, etc.), the screen can maintain high transparency while displaying images, thereby achieving the effect of "being able to see the content on the screen and also see the objects behind the screen".

[0003] Currently, existing LED holographic transparent display modules suffer from the following technical problems: 1. Low transmittance: The display effect of existing LED holographic displays is affected by different ambient light conditions. For example, in strong light, the screen may lack clarity due to insufficient brightness; in low light, excessive brightness will significantly reduce the transparency, affecting the display effect. 2. Poor heat dissipation: LED beads generate a lot of heat during operation. If heat dissipation is not timely and effective, the temperature of the beads will rise, affecting their luminous efficiency and lifespan. Moreover, high temperatures may also cause malfunctions of internal electronic components, reducing the stability and reliability of the screen. 3. Inconvenient installation and maintenance: Existing LED holographic transparent display modules require complete disassembly of the microcontroller box. The installation and disassembly processes are relatively complex, usually requiring specialized tools and techniques. This not only increases installation costs and time but also places high demands on the technical skills of the installers. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a holographic transparent display module and display device, which solves the problems of low transparency, poor heat dissipation, and inconvenient installation and maintenance of LED holographic transparent display modules in the prior art.

[0005] To achieve the above objectives, this utility model provides a holographic transparent display module, comprising:

[0006] The display component includes a transparent light panel and a plurality of light-emitting units disposed on the transparent light panel;

[0007] The microcontroller assembly includes a microcontroller box, a connection structure, and a heat dissipation structure. The microcontroller box is installed on one side of the transparent light panel to reduce the obstruction of light passing through the transparent light panel.

[0008] The microcontroller box includes: a box body, an electrical unit disposed in the box body, and a box cover that cooperates with the box body. The box cover is closed or opened with the box body through the connection structure to facilitate maintenance.

[0009] The heat dissipation structure is disposed on the cover to dissipate heat from the electrical unit.

[0010] As a preferred approach, the heat dissipation structure includes multiple spaced-apart heat dissipation fins disposed on the outer surface of the housing cover, allowing the heat generated by the microcontroller components to dissipate promptly. By increasing the heat dissipation surface area, the heat dissipation fins significantly increase the area in contact with air, making it easier for heat to dissipate through convection (natural or forced) and radiation. By creating a low-resistance, high-efficiency heat conduction path from the electrical unit → housing → housing cover → heat dissipation fins → air, a low-resistance, high-efficiency heat conduction path is formed, effectively preventing electrical components (such as control cards) within the microcontroller housing from experiencing frequency reduction, aging, or failure due to high temperatures, thus improving the overall stability and lifespan of the module. Furthermore, since the heat dissipation fins are disposed on the outer surface of the housing cover, and the housing cover itself is mounted on one side of the transparent light panel, the fins are not directly located in the display light path or affect the light-transmitting area of ​​the transparent light panel. The spaced-apart design also avoids large areas of continuous obstruction, further reducing interference with the display effect.

[0011] As a preferred embodiment, the connection structure includes a connecting seat disposed on the housing and a connecting latch disposed on the edge of the housing cover. The connecting seat and the connecting latch cooperate to open or close the housing cover relative to the housing body. This connection structure achieves a simple and flexible connection between the housing cover and the housing body. Users can easily open or close the housing cover with simple operations (such as pressing, rotating, or flicking the connecting latch) without the need for additional tools, greatly improving the efficiency of maintenance and repair. In addition, this connection structure can effectively fix the housing cover in the closed state, ensuring that it fits tightly against the housing body. This not only enhances the overall structural stability but also provides reliable physical protection for the delicate internal electrical components, preventing damage to the components from external dust, moisture, or accidental collisions, thereby improving the module's service life and operational reliability. Furthermore, since both the connecting seat and the connecting latch are located at the edges of the housing body and the housing cover, this design does not occupy internal space, which is conducive to achieving a compact layout of the microcontroller components and even the entire display module, realizing reasonable space utilization.

[0012] As a more preferred embodiment, the connecting latch includes a base, a handle, and a latch. One end of the handle is rotatably mounted on the base, and one end of the latch is rotatably hinged to the handle. This connecting latch achieves a simple and smooth user experience by rotating the handle to drive the latch, allowing for easy operation and smooth opening and closing. Users only need to apply a small force to the handle (such as a light press or flick) to move the latch through leverage, thus unlocking or locking the lid. No complicated operating steps or tools are required, greatly improving the convenience of maintenance and repair. Furthermore, because the latch and handle are connected by a rotatable hinge, the latch can flexibly adjust its angle according to the shape of the mating surface, enhancing its adaptability to the connecting seat or slot and ensuring a firm and reliable locking effect under different usage conditions, thus improving the stability and security of the connection. In addition, the compact layout of the "base + handle + buckle" structure, with all components located on the edge of the lid or body, does not occupy additional internal space. This facilitates the thinning and integration of the micro-control components and the overall display module, meeting the current high requirements of electronic devices for miniaturization and space utilization.

[0013] As a preferred embodiment, the electrical unit further includes a control card, a power port, a communication port, and an adapter board. The power port and communication port are mounted on the adapter board, and the control card is installed inside the housing. This design achieves modular management of the interfaces by centrally arranging the external interfaces (power and communication) on the adapter board and rationally separating and connecting them with the control card. This not only makes the access of external cables more convenient and neat but also reduces the risk of signal interference or accidental contact caused by spatial overlap and chaotic arrangement between the interfaces and the internal core circuitry, thus improving the electrical safety and signal integrity of the system. Furthermore, this design independently installs the control card inside the housing, away from the external interface area, which helps reduce the impact of external electromagnetic interference on the core control signals. It also facilitates heat dissipation layout and protection design for the control card, further improving the operational stability and reliability of the core control circuitry. Moreover, since the power port and communication port are concentrated on the adapter board, this design allows for pre-installation and pre-testing of the interfaces during assembly, simplifying the overall assembly process and improving production efficiency and product consistency.

[0014] As a preferred embodiment, the transparent light panel is further provided with at least one connecting post fixedly connected to the microcontroller box, and a connector for connecting power signals. By providing the connecting post on the transparent light panel, a direct and stable mechanical connection between the transparent light panel and the microcontroller box can be achieved, allowing for precise alignment and a secure connection between the two. This enhances the overall structural strength and vibration and deformation resistance of the module, making it particularly suitable for applications requiring long-term stable operation or installation in dynamic environments. Furthermore, by integrating the power signal connector on the transparent light panel, standardized and modular access to the power supply required by the light-emitting unit is achieved. This avoids problems such as loose power cable solder joints, poor contact, or maintenance difficulties that may exist in traditional methods. The connector not only improves the reliability and safety of the power connection but also makes power line access more convenient and pluggable, facilitating subsequent maintenance and replacement, and improving overall production efficiency and product consistency. Furthermore, this design integrates the connecting pillars and power signal connectors onto the transparent light panel, enabling the transparent light panel to not only perform the display function in the display module, but also to become the structural and electrical hub connecting the microcontroller box and the light-emitting unit. This helps to achieve a compact layout, coordinated optimization, and functional integration among the various components (transparent light panel, microcontroller box, and light-emitting unit) within the display module, further reducing the overall size and assembly complexity.

[0015] As a preferred approach, the transparent light panel features perforations on its back to increase visual transparency. This design, by removing a portion of the solid material from the non-display surface (back) of the transparent light panel to create a perforated area, effectively reduces visual obstruction caused by structural components, fixed columns, or mounting bases when viewing from behind the light panel. This allows users to obtain a clearer, more continuous, and unobstructed visual experience when observing scenes, objects, or environments behind the light panel, thereby enhancing the core characteristics of the transparent display module: high transparency and a sense of perspective. This is particularly suitable for applications requiring high background transparency, such as display cases, shop windows, glass curtain walls, or vehicle-mounted transparent displays. Furthermore, the perforated design does not affect the display function on the front of the transparent light panel, as the light-emitting units can still be normally installed on the front of the light panel or embedded in the transparent substrate. The perforated area is only located on the back and does not directly overlap or interfere with the display area. This ensures the integrity and consistency of the display effect while improving the perspective, achieving a balance between structural optimization and display performance. Furthermore, the shape, size, distribution density, and position of the perforated holes can be customized according to the actual installation structure and optical effect requirements, thereby meeting the personalized needs of different application scenarios.

[0016] As a preferred approach, the heat sink fins are made of aluminum or copper, with gaps between adjacent fins to form heat dissipation channels. By using metals with extremely high thermal conductivity, such as aluminum or copper, the heat sink fins can quickly absorb and conduct heat from the electrical units, significantly shortening the time it takes for heat to transfer from the heat source to the heat dissipation interface. This effectively reduces the operating temperature of internal components, avoiding performance degradation, shortened lifespan, or failure risks caused by overheating, thereby improving the overall operational stability and reliability of the holographic transparent display module. Furthermore, by maintaining appropriate gaps between adjacent heat sink fins to form multiple parallel heat dissipation channels, this design significantly increases the contact area between the heat sink and the surrounding air, as well as airflow. This facilitates the rise of hot air and the replenishment of cold air under natural convection conditions, further improving heat dissipation efficiency and achieving more efficient temperature control.

[0017] As a preferred approach, a holographic transparent display module device includes a light-transmitting carrier and the holographic transparent display module, with the transparent light panel adhered to the light-transmitting carrier. By directly adhering the transparent light panel to the light-transmitting carrier, the display module and the light-transmitting carrier can be integrated into a single structure. This not only simplifies the additional complex assembly structure that might be required in traditional designs but also significantly improves the installation and assembly efficiency of the entire display device. Furthermore, this design allows the transparent light panel and the light-transmitting carrier to form a continuous transparent display area at the optical level, which helps reduce light refraction, reflection, or scattering losses caused by intermediate layers or air gaps. This optimizes the contrast, brightness uniformity, and visual clarity of the displayed image, providing users with a more natural, coherent, and highly transparent visual experience when viewing from one side of the display surface. This strengthens the core characteristics of "holographic transparent display" and enhances the overall display effect and user immersion. Furthermore, by using adhesive bonding, a stable and reliable physical connection can be achieved between the transparent light panel and the light-transmitting carrier. This not only enhances the structural stability and anti-detachment ability of the module during long-term use, but also simplifies the disassembly and assembly operations during subsequent maintenance or replacement, thereby improving the durability of the equipment and the convenience of engineering implementation.

[0018] As a preferred approach, the holographic transparent display module display device includes multiple holographic transparent display modules, which are assembled into a complete transparent screen on the light-transmitting carrier. This modular assembly method enables the construction of large-size transparent display screens, meeting current market demands for large images, high transparency, and continuous visual effects. It is particularly suitable for large commercial display windows, ultra-long glass curtain walls, and other similar scenarios. Furthermore, the modular design allows each holographic transparent display module to be independently controlled, maintained, or replaced. In the event of a partial failure, the entire screen does not need to be replaced; only the problematic module needs repair or replacement, reducing operating and maintenance costs and improving the reliability, serviceability, and long-term economic efficiency of the entire display device. Moreover, this assembly design offers excellent scalability and adaptability. Users can freely choose the number, arrangement (horizontal / vertical / matrix), and layout density of modules based on the size of the installation area and the required display content resolution. This allows for on-demand customization of transparent screens from small to large sizes, meeting the personalized needs of different application scenarios and expanding the product's market application scope.

[0019] As described above, the holographic transparent display module display device of this utility model has the following beneficial effects: When the holographic transparent display module display device of this utility model is used, the transparent light panel is pasted on the transparent light panel. The light-emitting units on the transparent light panel have good light transmission characteristics, which can maintain the perspective effect of the background scenery to the greatest extent while realizing the display of images or information, thereby improving the user experience of the product.

[0020] The microcontroller unit is used for centralized management and control of parameters such as display content, brightness, and color of the light-emitting units. It comprises a microcontroller box, a connection structure, and a heat dissipation structure, featuring a rational layout and high functional integration. The microcontroller box is installed on one side of the transparent light panel, its position designed to minimize light obstruction, ensuring that the light transmittance of the transparent light panel is not significantly affected by the internal control components, thus maintaining the core advantage of holographic transparent displays.

[0021] In addition, the microcontroller box adopts a structure in which the box body and the cover fit together, and the cover and the box body are closed or opened through a connecting structure. This design makes the maintenance of electrical units (such as control cards, power modules, communication modules, etc.) more convenient. Users or technicians do not need to disassemble the entire module. They can simply open the cover to inspect, replace or upgrade the internal circuits or control components, which greatly reduces the difficulty and cost of maintenance, while improving the serviceability and long-term reliability of the equipment.

[0022] By placing the heat dissipation structure on the cover and using the cover as a heat dissipation surface, the heat generated by the electrical unit during operation can be effectively dissipated, avoiding the performance degradation or shortened lifespan of electronic components due to excessive temperature. This ensures the stable operation of the control system and extends the service life of the module. At the same time, the external heat dissipation method also avoids interference with the internal display area and light transmission performance. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.

[0050] like Figures 1 to 6 As shown, this utility model provides a holographic transparent display module, comprising:

[0051] Display component 1, the display component 1 includes a transparent light panel 11 and a plurality of light-emitting units disposed on the transparent light panel 11;

[0052] The microcontroller component 2 includes a microcontroller box 21, a connection structure 22, and a heat dissipation structure 23. The microcontroller box 21 is installed on one side of the transparent light panel 11 to reduce the obstruction of light passing through the transparent light panel 11.

[0053] The microcontroller box 21 includes: a box body 211, an electrical unit 213 disposed within the box body 211, and a box cover 212 that cooperates with the box body 211. The box cover 212 is closed or opened with the box body 211 through the connecting structure 22 to facilitate maintenance.

[0054] The heat dissipation structure 23 is disposed on the cover 212 to dissipate heat from the electrical unit 213.

[0055] In some embodiments of this utility model, such as Figures 1 to 3As shown, the heat dissipation structure 23 includes multiple spaced heat dissipation fins 231, which are disposed on the outer surface of the cover 212 to dissipate the heat generated by the microcontroller component 2 in a timely manner. The heat dissipation fins 231 significantly increase the surface area in contact with air by increasing the heat dissipation surface area, making it easier for heat to dissipate through convection (natural or forced) and radiation. By creating a low-resistance, high-efficiency heat conduction path from the electrical unit 213 → housing 211 → cover 212 → heat dissipation fins 231 → air, a low-resistance, high-efficiency heat conduction path is formed, effectively preventing electrical components (such as control cards) inside the microcontroller box 21 from experiencing frequency reduction, aging, or failure due to high temperatures, thus improving the overall stability and lifespan of the module. Furthermore, since the heat dissipation fins 231 are disposed on the outer surface of the cover 212, and the cover 212 itself is installed on one side of the transparent light panel 11, the fins are not directly located in the display light path or affect the light-transmitting area of ​​the transparent light panel 11. The spaced design also avoids large-area continuous obstructions, further reducing interference with the display effect.

[0056] In some embodiments of this utility model, such as Figure 3 As shown, the connection structure 22 includes a connecting seat 222 disposed on the housing 211 and a connecting latch 221 disposed on the edge of the lid 212. The connecting seat 222 and the connecting latch 221 are connected to each other to allow the lid 212 to open or close relative to the housing 211. This connection structure 22 achieves the effect of simple connection and flexible operation between the lid 212 and the housing 211. Users can easily open or close the lid 212 with simple operations (such as pressing, rotating, or flicking the connecting latch 221) without the need for additional tools, greatly improving the efficiency of maintenance and repair. In addition, the connection structure 22 can effectively fix the lid 212 in the closed state, ensuring that it fits tightly with the housing 211. This not only enhances the stability of the overall structure but also provides reliable physical protection for the delicate internal electrical components, preventing damage to the components from external dust, moisture, or accidental collisions, thereby improving the service life and operational reliability of the module. Furthermore, since both the connector 222 and the connector latch 221 are located at the edges of the housing 211 and the cover 212, this design does not occupy internal space, which is conducive to achieving a compact layout of the microcontroller component 2 and even the entire display module, and realizing reasonable space utilization.

[0057] In some embodiments of this utility model, such as Figure 3As shown, the connecting latch 221 includes a base, a handle, and a latch. One end of the handle is rotatably mounted on the base, and one end of the latch is rotatably hinged to the handle. In use, the user applies an operating force to the handle of the connecting latch 221, causing the handle to rotate and the latch to rotate. Since one end of the latch is rotatably hinged to the handle, when the handle rotates, the latch will also change its angle accordingly. This rotation will cause the latch portion, which was originally tightly engaged with the connecting seat 222, to disengage from the engaging position of the connecting seat 222 (e.g., exit from the slot, separate from the hook, or release mechanical interference); the latch is released, and the lid 212 can be opened; the lid 212 is then aligned with... Align the box body 211 with the connecting latch 221 close to the connecting seat 222, and manually adjust the position of the box cover 212 so that the latch aligns with the engaging part (such as a slot or hook) on the connecting seat 222. Reverse the rotation of the handle (e.g., release the press, rotate the handle, or push the latch) to allow the latch to rotate again and engage with the connecting seat 222, restoring the engagement. Once the latch and connecting seat 222 have re-established a stable fit, the box cover 212 is locked onto the box body 211, returning to the closed state. This connecting latch 221, driven by the rotation of the handle, provides a simple and smooth opening and closing experience. Users only need to apply a small force to the handle (such as a light press or flick) to move the latch through leverage, thus unlocking or locking the box cover 212. No complicated operating steps or tools are required, greatly improving the convenience of maintenance and repair. Secondly, due to the hinged connection between the buckle and the rotating handle, the buckle can flexibly adjust its angle according to the shape of the actual mating surface, enhancing its adaptability to the connecting seat 222 or the slot. This ensures a firm and reliable locking effect under different usage conditions, improving the stability and security of the connection. Furthermore, the compact layout of the "base + rotating handle + buckle" structure, with all components located at the edge of the cover 212 or the body 211, does not occupy additional internal space. This facilitates the slim and integrated design of the microcontroller component 2 and the overall display module, meeting the current high requirements of miniaturization and space utilization in electronic devices.

[0058] In some embodiments of this utility model, such as Figure 1As shown, the electrical unit 213 also includes a control card, a power port, a communication port, and an adapter board. The power port and communication port are mounted on the adapter board, and the control card is installed inside the housing 211. This design achieves modular management of the interfaces by centrally arranging the external interfaces (power and communication) on the adapter board and rationally separating and connecting them with the control card. This not only makes the access of external cables more convenient and neat, but also reduces the risk of signal interference or accidental contact caused by spatial overlap and chaotic arrangement between the interfaces and the internal core circuit, thus improving the electrical safety and signal integrity of the system. In addition, this design independently installs the control card inside the housing 211, away from the external interface area, which helps to reduce the impact of external electromagnetic interference on the core control signals. It also facilitates heat dissipation layout and protection design for the control card, further improving the operational stability and reliability of the core control circuit. Furthermore, since the power port and communication port are concentrated on the adapter board, this design allows for pre-installation and pre-testing of the interfaces during assembly, simplifying the overall assembly process and improving production efficiency and product consistency.

[0059] In some embodiments of this utility model, such as Figures 5 to 6 As shown, the transparent light panel 11 is also provided with at least one connecting post 111 fixedly connected to the microcontroller box 21, and a connector 112 for connecting power signals. By providing the connecting post 111 on the transparent light panel 11, a direct and stable mechanical connection between the transparent light panel 11 and the microcontroller box 21 can be achieved, enabling the transparent light panel 11 and the microcontroller box 21 to be precisely aligned and firmly connected, enhancing the overall structural strength and vibration and deformation resistance of the module, which is especially suitable for application scenarios requiring long-term stable operation or installation in dynamic environments. In addition, by integrating the power signal connector 112 on the transparent light panel 11, the standardized and modular access of the power required by the light-emitting unit is achieved, avoiding problems such as loose power line solder joints, poor contact, or maintenance difficulties that may exist in traditional methods. Through the connector 112, not only is the reliability and safety of the power connection improved, but the access of the power line is also more convenient and pluggable, facilitating subsequent maintenance and replacement, and improving overall production efficiency and product consistency. Furthermore, this design integrates both the connecting post 111 and the power signal connector 112 onto the transparent light panel 11, so that the transparent light panel 11 not only undertakes the display function in the display module, but also becomes the structural and electrical hub connecting the microcontroller box 21 and the light-emitting unit. This helps to achieve a compact layout, coordinated optimization and functional integration among the various components (transparent light panel 11, microcontroller box 21, and light-emitting unit) inside the display module, further reducing the overall size and assembly complexity.

[0060] In some embodiments of this utility model, such as Figures 5 to 6As shown, the transparent light panel 11 has a perforated hole on its back to increase the visual transparency of the back of the transparent light panel 11. This design, by removing part of the solid material from the non-display surface (back) of the transparent light panel 11 to form a perforated area, effectively reduces visual obstruction caused by structural components, fixed columns, or mounting bases when viewing from behind the light panel. This allows users to obtain a clearer, more continuous, and unobstructed visual experience when observing the scene, objects, or environment behind the light panel, thereby enhancing the core characteristics of the transparent display module: "high transparency" and "perspective." It is particularly suitable for applications with high requirements for background perspective, such as display cabinets, shop windows, glass curtain walls, or vehicle-mounted transparent displays. In addition, the perforated hole design does not affect the display function of the front of the transparent light panel 11, because the light-emitting unit can still be installed normally on the front of the light panel or embedded in the transparent substrate. The perforated area is only located on the back and does not directly overlap or interfere with the display area. Thus, while improving the perspective effect, it ensures the integrity and consistency of the display effect, achieving a balance between structural optimization and display performance. For example, the shape, size, distribution density, and position of the perforated holes can be customized according to the actual installation structure and optical effect requirements, thereby meeting the personalized needs of different application scenarios.

[0061] In some embodiments of this utility model, such as Figure 1 As shown, the heat dissipation fins 231 are made of aluminum or copper, and there are gaps between adjacent heat dissipation fins 231 to form heat dissipation channels. By using metals with extremely high thermal conductivity, such as aluminum or copper, the heat dissipation fins 231 can quickly absorb and conduct heat from the electrical unit 213, significantly shortening the time for heat to transfer from the heat source to the heat dissipation interface, effectively reducing the operating temperature of internal components, and avoiding performance degradation, shortened lifespan, or failure risks caused by overheating, thereby improving the overall operational stability and reliability of the holographic transparent display module. In addition, by maintaining appropriate gaps between adjacent heat dissipation fins 231 to form multiple parallel heat dissipation channels, this design significantly increases the contact area between the heat sink and the surrounding air and the airflow, which is conducive to the rise of hot air and the replenishment of cold air under natural convection conditions, thereby further improving heat dissipation efficiency and achieving more efficient temperature control.

[0062] In some embodiments of this utility model, such as Figures 5 to 6As shown, a holographic transparent display module device includes a light-transmitting carrier 12 and the holographic transparent display module, with a transparent light panel 11 attached to the light-transmitting carrier 12. By directly attaching the transparent light panel 11 to the light-transmitting carrier 12 (such as glass, acrylic, etc.), the display module and the light-transmitting carrier 12 can be integrated into a single structure. This not only simplifies the additional complex assembly structure that may be required in traditional designs but also significantly improves the installation and assembly efficiency of the entire display device. Furthermore, this design allows the transparent light panel 11 and the light-transmitting carrier 12 to form a continuous transparent display area at the optical level. This helps reduce light refraction, reflection, or scattering losses caused by intermediate layers or air gaps, optimizing the contrast, brightness uniformity, and visual clarity of the displayed image. This allows users to obtain a more natural, coherent, and highly transparent visual experience when viewing from one side of the display surface, thereby strengthening the core characteristics of "holographic transparent display" and improving the overall display effect and user immersion. Furthermore, by using adhesive bonding, a stable and reliable physical connection can be achieved between the transparent light panel 11 and the light-transmitting carrier 12. This not only enhances the structural stability and anti-detachment ability of the module during long-term use, but also simplifies the disassembly and assembly operations during subsequent maintenance or replacement, thereby improving the durability of the equipment and the convenience of engineering implementation.

[0063] In some embodiments of this utility model, such as Figures 5 to 6 As shown, the holographic transparent display module display device includes multiple holographic transparent display modules, and the multiple display components 1 are assembled into a complete transparent screen on the light-transmitting carrier 12. Through modular assembly, a large-size transparent display screen can be constructed, meeting the current market demand for large screens, high transparency, and continuous visual effects, making it particularly suitable for large commercial display windows, ultra-long glass curtain walls, and other scenarios. Furthermore, the modular design allows each holographic transparent display module to be independently controlled, maintained, or replaced. In the event of a partial failure, there is no need to replace the entire screen; only the problematic module needs to be repaired or replaced, reducing operating and maintenance costs and improving the reliability, serviceability, and long-term economic efficiency of the entire display device. Moreover, this assembly design possesses excellent scalability and flexible adaptability. Users can freely choose the number, arrangement (horizontal / vertical / matrix), and layout density of modules according to the size of the installation area and the resolution requirements of the display content, thereby achieving on-demand customization from small to ultra-large sizes of transparent screens, meeting the personalized needs of different application scenarios, and expanding the market application scope of the product.

[0064] As described above, the holographic transparent display module display device of this utility model has the following beneficial effects: When the holographic transparent display module display device of this utility model is used, the transparent light panel 11 is pasted on the transparent light panel 11. The light-emitting units on the transparent light panel 11 have good light transmission characteristics, which can maintain the perspective effect of the background scenery to the greatest extent while realizing the display of images or information, thereby improving the user experience of the product.

[0065] The microcontroller component 2 is used to centrally manage and control the display content, brightness, color, and other parameters of the light-emitting unit. The microcontroller component 2 includes a microcontroller box 21, a connecting structure 22, and a heat dissipation structure 23, featuring a reasonable structural layout and high functional integration. The microcontroller box 21 is installed on one side of the transparent light panel 11, and its position design fully considers minimizing light obstruction, ensuring that the light transmission performance of the transparent light panel 11 is not significantly affected by the internal control components, thereby maintaining the core advantage of holographic transparent display.

[0066] In addition, the microcontroller box 21 adopts a structure in which the box body 211 and the box cover 212 cooperate, and the box cover 212 and the box body 211 are closed or opened through the connecting structure 22. This design makes the maintenance of electrical units 213 (such as control cards, power modules, communication modules, etc.) more convenient. Users or technicians do not need to disassemble the entire module. They can simply open the box cover 212 to inspect, replace or upgrade the internal circuits or control components, which greatly reduces the difficulty and cost of maintenance, while improving the serviceability and long-term reliability of the equipment.

[0067] The heat dissipation structure 23 is set on the cover 212. Using the cover 212 as a heat dissipation surface, the heat generated by the electrical unit 213 during operation can be effectively dissipated, avoiding the degradation of electronic component performance or shortening of life due to excessive temperature. This ensures the stable operation of the control system and extends the service life of the module. At the same time, the external heat dissipation method also avoids interference with the internal display area and light transmission performance.

[0068] In summary, the holographic transparent display module display device of this utility model has the following advantages:

[0069] 1. Modular design for convenient and efficient maintenance:

[0070] The microcontroller box 21 adopts a structure in which the box body 211 and the box cover 212 cooperate. The box cover 212 can be easily opened and closed through the connecting structure 22, so that the maintenance of the electrical unit 213 (such as control card, power module, communication module, etc.) does not require the overall disassembly of the module. It can be operated simply by opening the box cover 212, which greatly reduces the maintenance difficulty and cost.

[0071] 2. Efficient heat dissipation ensures stable system operation:

[0072] The heat dissipation structure 23 is set on the cover 212. Using the cover 212 as a heat dissipation surface, it can effectively dissipate the heat generated by the electrical unit 213, avoid the impact of high temperature on the performance and life of electronic components, and ensure the stable operation of the control system.

[0073] 3. High transparency and good perspective:

[0074] The transparent light panel 11 has excellent light transmission characteristics. While displaying images or information, the light-emitting unit can maintain the perspective effect of the background objects to the greatest extent, which enhances the visual hierarchy of the product and the user experience, and fully reflects the core advantage of "transparent display".

[0075] 4. High visual transparency:

[0076] The micro-control box 21 is installed on one side of the transparent light panel 11. Its scientifically designed position effectively reduces the obstruction of light passing through the transparent light panel 11, ensuring that the light transmission performance of the transparent light panel 11 is not significantly affected by the internal control components, and maintaining the visual transparency of the holographic transparent display.

[0077] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
