[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-4 The present invention relates to a dynamic naked-eye panoramic fully digital immersive display device with a lower-cut horizontal cylindrical body, comprising a horizontal cylindrical frame 1, an LED display module 4, a rectangular galvanized steel pipe 2, and a fixing component 3. The LED display module 4 is spliced ​​to form a 360-degree annular display surface. The bottom of the horizontal cylindrical frame 1 is provided with a lower cut surface. The rectangular galvanized steel pipe 2 is distributed along the axial direction of the horizontal cylindrical frame 1 and fixes the LED display module 4. The fixing component 3 connects the rectangular galvanized steel pipe 2 and the LED display module 4.

[0035] Imaging principle of transverse cylinder with lower cut surface

[0036] The device supports the curved LED display module 4 via a horizontal cylindrical frame 1, forming a horizontally cylindrical space with an open bottom and a slanted surface. The panoramic (720-degree) dynamic film is segmented into sub-screens that match the curved LED surface using an algorithm. After being displayed synchronously by each module, it forms a continuous surround image within the cylinder. Viewers enter from the open area of ​​the slanted surface and can watch the seamless 360-degree panoramic view from the top and sides without wearing any equipment, achieving an immersive experience with sound field positioning.

[0037] Structural support and fixing principles

[0038] Horizontal cylindrical frame 1 and rectangular galvanized steel pipe 2:

[0039] The rectangular galvanized steel pipes 2 are evenly distributed along the axial direction of the transverse cylindrical frame 1. The inner groove and U-shaped clamp cooperate to form a fixed structure of "steel pipe-groove-U-shaped clamp". The rectangular galvanized steel pipes 2 can be installed inside the transverse cylindrical frame 1 by bolting.

[0040] U-shaped clips for magnetic fixation:

[0041] The U-shaped clamp has a built-in magnet that magnetically attaches to the clamping groove, enabling quick installation and removal of the LED display module 4, thus avoiding damage to the screen body caused by welding.

[0042] Fixed frame 6 stable support:

[0043] The fixed frames 6 at both ends of the horizontal cylindrical frame 1 are ring-shaped metal profiles. After assembly, they are fixed to the ground by the counterweight base 7 (with built-in expansion bolts 8) to ensure the equipment's anti-overturning stability. The fixed frame 6 is installed on the horizontal cylindrical frame 1 using a bolt structure, and the counterweight base 7 is installed using a bolt structure.

[0044] Principles of Optimal Technical Solution

[0045] Curvature matching of curved screens:

[0046] Curved screen design: Each display screen 5 has a specific radius of curvature that matches the diameter of the horizontal cylindrical frame 1, ensuring that a complete 360-degree cylindrical display surface is formed after splicing. The display screen 5 can be protected by covering it with tempered glass.

[0047] Modular design: Supports flexible combination of LED screens of different sizes and resolutions to adapt to various application scenarios.

[0048] Preferred solution for fastener 3

[0049] U-shaped clip + magnetic sheet structure:

[0050] The U-shaped clamp fits tightly with the galvanized steel pipe through a slot.

[0051] The inner arm is embedded with a magnetic piece, which generates an adsorption force with the surface of the galvanized steel pipe, improving the connection rigidity;

[0052] It can be quickly installed / removed, reducing maintenance difficulty.

[0053] Preferred Scheme 2 for Rectangular Galvanized Steel Pipe

[0054] Groove structure: A strip groove is set along the inner side of the pipe body to precisely fit the U-shaped clamp and ensure accurate installation positioning;

[0055] Bolted connection at both ends: The two ends of the steel pipe are connected to the transverse cylindrical frame 1 by bolts to enhance the overall structural rigidity and disassembly.

[0056] Preferred configuration of transverse cylindrical frame 1 and fixed frame 6

[0057] Fixed frame 6 set structure: It is fitted at both ends of the horizontal cylindrical frame 1, which combines aesthetics and functionality, and facilitates wiring management and structural reinforcement.

[0058] Preferred solution for counterweight base 7 and expansion bolt 8

[0059] Counterweight base 7: Contains internal weights (such as concrete or metal blocks) to improve equipment stability;

[0060] Expansion bolt 8: Securely anchor the base to the ground to prevent displacement or tilting.

[0061] Open design with lower facets:

[0062] The bottom bevel creates an entrance and exit passage for the audience, while preserving the surround image effect on the top and sides. Soft protective edging is provided along the edges of the bevel to prevent collisions and enhance safety.

[0063] Modular signal processing: The panoramic video is divided into sub-screens corresponding to the number of LED modules (e.g., 12 screens correspond to 12 signals) by an algorithm. Each screen is driven to display synchronously by a synchronous controller, with a delay error of ≤10ms, ensuring the continuity of dynamic images.

[0064] Video segmentation algorithm

[0065] Video segmentation is the process of dividing a panoramic video source into multiple sub-frames, with each sub-frame corresponding to an LED module. This is a common technique in the fields of image processing and computer vision.

[0066] Frame segmentation algorithm: Based on screen resolution and layout, each frame image is segmented into sub-images corresponding to the number of LED modules. For example, for a 360-degree panoramic video, if 12 screens are used for display, each frame image needs to be evenly divided into 12 parts.

[0067] Content-aware segmentation: More advanced segmentation methods may consider the video content itself to optimize segmentation strategies and avoid cutting or distorting key content.

[0068] Synchronization control algorithm

[0069] The synchronization controller is responsible for managing the synchronized display between all LED modules, ensuring that all screens can start playing their respective parts at the same time and maintain a consistent speed and timeline.

[0070] Time synchronization protocols (such as PTP, Precision Time Protocol): are used to accurately synchronize the time of distributed devices in a network environment, which is crucial for the synchronization of multi-screen systems.

[0071] Buffering and Latency Compensation: Due to potential delays introduced by network transmission or hardware processing, the system employs appropriate buffering mechanisms to minimize the impact of these delays, ensuring that content on all screens is as synchronized as possible. A latency error requirement of ≤10ms means the system must adjust the playback timing between each screen with extremely high precision.

[0072] Ensuring the continuity of dynamic images

[0073] To ensure the continuity of dynamic images displayed on multiple screens, in addition to the synchronization control mentioned above, the following points should also be noted:

[0074] Color calibration and brightness matching: Ensure consistent color performance and brightness levels across all screens to avoid visual discontinuity caused by hardware differences.

[0075] Edge blending technology: If there are physical seams between screens, edge blending technology can be used to soften the boundaries and make the transition smoother and more natural.

[0076] The device has a compact structure and a strong visual immersion, making it suitable for scenarios such as virtual reality, exhibitions, and gaming experiences, and enabling high-quality naked-eye panoramic dynamic image presentation.

[0077] Detailed Workflow

[0082] Insert the curved LED display module 4 into the U-shaped clip in sequence, and fix it using the magnetic attraction and slot structure;

[0083] The mounting frame 6 is fitted onto both ends of the horizontal cylindrical frame 1, serving to reinforce the structure and guide wiring.

[0084] Install the counterweight base 7 and fix it to the ground using expansion bolts 8;

[0085] Connect the power supply, control circuitry, and network interface.

[0086] Step 2: Signal Access and Debugging Phase

[0087] Input a panoramic video source, and the signal processor will perform split-screen processing to generate sub-screens corresponding to the number of LED modules;

[0088] Each sub-screen signal is transmitted to the corresponding display screen 5, and is uniformly scheduled by the synchronization controller to ensure that the playback delay error is ≤10ms;

[0089] Activate the naked-eye stereo vision optimization algorithm to adjust parallax and rendering effects in real time based on the user's position.

[0090] Step 3: Immersive Display Operation Phase

[0091] Multiple displays 5 simultaneously play sub-screens, forming a continuous 360-degree panoramic image;

[0092] Viewers can move freely inside the cylinder, gaining a completely immersive visual experience without blind spots;

[0093] The system continuously monitors signal synchronization status and environmental parameters such as temperature and humidity, and automatically adjusts brightness and color performance accordingly.

[0094] To replace or repair display screen 5, simply loosen the corresponding U-shaped clip for quick disassembly.
