Description

Technical Field

[0001] This utility model relates to the field of immersive media display equipment technology, specifically a vertical cylindrical rounded corner still frame panoramic digital RVR naked-eye immersive display device. Background Technology

[0002] Traditional flat screens or curved projections struggle to achieve immersive, all-around visual experience. Dome or panoramic cinemas, on the other hand, rely heavily on projection splicing or VR headsets, which suffer from uneven brightness, noticeable seams, high equipment costs, and discomfort. In recent years, panoramic display devices based on LEDs or light boxes have gradually emerged, but most are horizontal cylindrical or cubic structures, allowing viewers to see only the side wall images and lacking top visual elements, resulting in limited immersion.

[0003] Existing vertical panoramic equipment often uses right-angle stitching or simple curved surfaces, which easily leads to wrinkles, distortions, or seams in the image at corners, affecting visual continuity. Inadequate support structure design and poor fit between the frame and the image cause bulging or loosening of flexible image layers such as UV-printed fabric. Backlighting systems are often centralized or irregularly arranged, resulting in uneven illumination, bright spots, or dark areas, severely impacting display quality. Some equipment does not consider efficient light utilization, causing a large amount of light to be absorbed by the inner walls, resulting in high energy consumption and low brightness.

[0004] In addition, the methods of fixing the screen are mostly nailing or using clips to press the edges, which are prone to loosening after long-term use and are inconvenient to maintain.

[0005] Meanwhile, if a right-angle transition is used at the connection between the closed end face and the side wall, it will create a visual hard edge and destroy the sense of immersion. Existing technologies lack effective solutions for structural adaptation and image support for rounded corner areas. Utility Model Content

[0027] 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.

[0028] Please see Figure 1-4 The present invention relates to a vertical cylindrical rounded corner still frame panoramic digital RVR naked-eye immersive display device, comprising a vertical cylindrical frame 1, a display module and a viewing platform;

[0029] The vertical cylindrical frame 1 is a hollow structure, one end of the vertical cylindrical frame 1 is a closed surface 10, the sides of the closed surface 10 of the vertical cylindrical frame 1 are rounded, and the viewing platform is located at the bottom of the vertical cylindrical frame 1.

[0030] The display module includes a support member, a UV inkjet printing cloth image layer 7, and LED light strips 5. The support member is arranged along the inner wall of the vertical cylindrical frame 1 and the closed surface 10 of the vertical cylindrical frame 1. The UV inkjet printing cloth image layer 7 is fixed on the support member, and the LED light strips 5 are evenly arranged behind the UV inkjet printing cloth image layer 7.

[0031] The vertical cylindrical frame 1 provides overall structural support for the equipment, forming a 360° panoramic display space. Its rounded corner closed surface 10 design eliminates visual edge sharpness and enhances immersion.

[0032] It adopts a hollow cylindrical structure, which is spliced ​​from high-strength aluminum alloy profiles. The bottom is fixed to the ground and the bottom is a closed surface 10. The sides of the closed surface 10 are designed with rounded corners. The rounded corners smoothly transition with the sides of the cylinder, solving the problem of image edge distortion caused by traditional right-angle structures. This allows the observer's field of view to extend from 360° horizontally to 120° at the top, expanding the immersive field of view.

[0033] The inner wall of the frame has pre-drilled mounting holes for fixing the support components and display module, ensuring structural stability.

[0034] The display module, through the synergistic effect of the UV inkjet cloth image layer 7 and the LED light strip 5, presents a high-definition, high-brightness 360° panoramic static image, achieving a naked-eye immersive visual experience.

[0035] The support is fixed along the inner wall of the cylindrical frame and the closed surface 10 to form a support structure, ensuring that the UV inkjet cloth image layer 7 is flat and wrinkle-free.

[0036] The UV inkjet printing fabric layer 7 uses seamless splicing technology to cover the inner wall of the cylindrical frame and the closed surface 10, forming a complete panoramic image; the content of the image can be customized according to needs, such as natural scenery, virtual scenes, etc.

[0037] The LED light strips 5 are evenly arranged behind the image layer, illuminating the printing cloth through diffuse reflection, which improves the color saturation of the image and eliminates the heat dissipation noise of the projection equipment.

[0038] LED light strip 5 supports zoned brightness adjustment, which can adjust the local brightness according to the content of the picture to enhance the sense of layering of the picture.

[0039] The observation platform provides a stable and safe viewing position, ensuring that observers are at the best vantage point for panoramic views and enhancing the immersive experience.

[0040] The viewing platform is located in the central area at the bottom of the cylindrical frame, and uses tempered glass 8 as the platform to ensure that observers can have a 360° unobstructed view of the surrounding and top views.

[0041] Support column 9 is fixed to the corner of the glass and connected to the bottom of the cylindrical frame, which can accommodate 5-10 people to stand and observe at the same time.

[0042] LED light strips 5 are arranged along the inner wall of the cylindrical frame and the closed surface 10, and are located in the gaps between several supporting members.

[0043] This solution embeds LED light strip 5 into the gap of the support component to ensure that the light travels a consistent distance through the inkjet cloth;

[0044] The gap arrangement reduces the obstruction of light by the support components, and together with the constant current drive design of the LED light strip 5, the brightness uniformity of the screen is ≥90%.

[0045] Reflective sequins are laid on the inner wall and closed surface 10 of the vertical cylindrical frame 1.

[0046] The reflective sequins are made of PET material, with a surface covered with micro-prism structures, and are laid between the support and the LED light strip 5;

[0047] When the LED light strip 5 emits light, the reflective glitter focuses and reflects the scattered light onto the UV inkjet fabric image layer 7, thereby increasing the brightness of the image and reducing the ineffective loss of light into the frame.

[0048] The diffuse reflection properties of the sequins can soften the graininess of the LED light strip 5, making the transition of the image more natural, and it is especially suitable for close-up viewing.

[0049] The support components include rectangular keel 2, arc-shaped keel 3 and circular keel 4, which are respectively adapted to the inner wall, rounded corners and closed surface 10.

[0050] Rectangular keel 2: Arranged in a ring along the inner wall of the vertical cylindrical frame 1 to ensure a flat inner wall surface.

[0051] Circular keel 4: Arranged step by step along the diameter towards the center on the closed surface 10, and fixed to the bottom image in accordance with the curvature of the closed surface 10;

[0052] Arc-shaped keel 3: It is arranged around the rounded corner structure on the side of the closed surface 10, connecting the rectangular keel 2 and the circular keel 4, eliminating the wrinkles at the corners of the image;

[0053] The three types of keel are connected by bolts to form an overall frame.

[0054] All three types of keels are equipped with H-code or F-code clamping grooves, and the UV inkjet printing cloth image layer is pressed into the grooves on all seven sides and bonded and fixed.

[0055] The edges of the printed fabric are pre-coated with special adhesive, pressed into the groove, and fixed by mechanical pressure for 24 hours to achieve a seamless effect that is visible to the naked eye.

[0056] The viewing platform is composed of tempered glass 8 and supporting columns 9, arranged along the bottom of the cylindrical frame.

[0057] The tempered glass 8 undergoes homogenization treatment, has a surface film to prevent breakage and splashing, and has rounded edges to avoid scratches;

[0058] The support column 9 is equipped with a shock-absorbing pad, which can absorb ground vibration and prevent noise from glass resonance.

[0059] The platform height is designed to be 300-500mm, so that the observer's line of sight is aligned with the vertical center line of the image, ensuring that a complete 360° image is formed on the retina and reducing visual fatigue.
