Description

Technical Field

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

[0002] Existing immersive display solutions mostly rely on VR / AR headsets. Although they can achieve a sense of virtual immersion, they suffer from problems such as discomfort when worn, strong dizziness, and difficulty in sharing among multiple people, which limits their widespread application in exhibitions, public art, and other scenarios.

[0003] Some panoramic display devices employ multi-screen splicing or circular rear projection structures, but they commonly suffer from visual discontinuities at image transitions, uneven color and brightness, and limited viewing angles. This is particularly true in frame corner areas, where the image is prone to breakage or distortion, severely impacting immersion. Furthermore, traditional lightbox structures are mostly right-angle splicing, lacking design adaptation for rounded corners and areas where multiple angles intersect, resulting in poor image continuity. Uneven light source placement also frequently creates bright spots or dark areas, affecting visual effects.

[0004] In terms of structural design, existing equipment mostly uses adhesive or screws to fix the image, which is prone to damaging the image layer and is inconvenient to replace; the support platform often uses metal pillars, which can easily obstruct the view and damage the integrity of the image. At the same time, the overall structural stability is insufficient, and problems such as loose parts and image displacement are prone to occur after long-term use. Utility Model Content

[0016] 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.

[0017] Please see Figure 1-6 The present invention relates to a cube-shaped, rounded-corner, still-frame panoramic digital RVR naked-eye immersive display device, comprising: A cube-shaped rounded corner frame 1, the inner wall of which is covered with a light box layer; The image layer 4 is disposed on the surface of the light box layer, and the light box layer is provided with an image slot 7. The edge of the image layer 4 is fixed by the image slot 7. A light-emitting layer is disposed on the inner side of the light box layer; The viewing platform is located at the bottom center of the cube-shaped rounded corner frame 1.

[0018] This technical solution uses a cube-shaped rounded frame as a carrier and layers collaboratively constructs a naked-eye still-frame immersive environment without visual breaks as its core logic. This allows users to obtain an immersive visual experience surrounded by the screen in 360° without wearing auxiliary devices such as VR glasses. The specific principle is as follows: Panoramic support for the frame and lightbox layer: The cube-shaped rounded corner frame adopts a fully enclosed cube with rounded corner transition structure. The lightbox layer covering the inner wall is spliced ​​together by rectangular lightbox 2, arc lightbox 11, and arc-shaped triangular lightbox 12. The rectangular lightbox 2 fits the six planes of the inner wall of the frame, the arc lightbox 11 fits the rounded corner edges of the frame 12 to avoid the image breaking at the corners, and the arc-shaped triangular lightbox 12 connects the eight rounded corners of the frame, such as the corners at the top or bottom. The three form a continuous inner wall without splicing breaks, providing a complete load-bearing foundation for the image layer 4. Layered collaborative display core: Light-emitting layer: It consists of a base plate 9 and evenly arranged LED light strips 6. The LED light strips 6 are precisely positioned through the light openings 5 ​​of the light box layer to provide a stable surface light source without dark areas. The light shines evenly on the inside of the light box layer to ensure that the picture layer 4 displays full colors. Lightbox layer: As a transitional carrier between the light-emitting layer and the image layer 4, its multi-type lightbox structure adapts to the frame shape. At the same time, the image layer 4 is fixed by the H / F code image slot 7 of the frame to prevent the image from shifting or wrinkling. The reflective glitter in the slot can reflect and scatter light to enhance the brightness of the image. Image layer 4: UV inkjet cloth is used to cover the surface of the lightbox layer to present a still frame panoramic image, such as natural scenery, digital art, etc. The closed structure of the cube frame allows the image to cover the user's 360° horizontal field of view and 180° vertical field of view, creating a naked-eye immersive feeling with the viewing platform as the center. Optimized viewing platform experience: The platform is located at the bottom center of the frame. When the user stands on the tempered glass 3, they are surrounded by the image layer 4. The high light transmittance of the acrylic support column 10 does not obstruct the ground view, achieving full visual coverage in all directions: up, down, left, right, front, and back, further enhancing the immersive surround experience.

[0019] The rectangular light box 2 is adapted to the 6 inner walls of a cube, the curved light box 11 is adapted to 12 rounded edges, and the arc-shaped triangular light box 12 is adapted to 8 intersections of multiple rounded corners. The rectangular lightbox 2 covers the flat area, and the curved lightbox 11 fits the rounded corners and edges through its curved shape to avoid the image breaking at the flat surface or corners. Traditional right-angle frames are prone to image misalignment. The curved triangular lightbox 12 connects the intersection of 3 or more lightboxes, such as the front right corner of the top of a cube, filling the gaps between multiple faces and achieving full-area image coverage of 6 faces, 12 edges and 8 corners. All types of light boxes use lightweight metal frames, such as aluminum alloy, which can be stably fixed to the inner wall of the cube frame. They will not sag or deform after long-term use, ensuring the flatness of the image.

[0020] The viewing platform consists of 8-12mm thick tempered glass 3 and 5-8cm diameter acrylic support columns 10. 4-6 support columns 10 are evenly distributed. The tempered glass 3 covers the bottom light box layer of the frame. The high strength of tempered glass 3 allows multiple people to stand on it at the same time (2-3 people), and when broken, it breaks into blunt-angled particles, posing no safety hazard. Acrylic support column 10 has a light transmittance of ≥92%, which will not block the image of the ground light box layer. Users can see the ground image when standing, achieving full-directional visual immersion. Traditional metal support column 10 easily blocks the ground view. The height of the support column 10 is designed so that the user's eyes are level with the center of the image layer 4 when standing, ensuring that the center of vision is aligned with the core area of ​​the image and avoiding visual fatigue caused by looking up or down.

[0021] The image slot 7 is located at the edge of the lightbox layer, using an H-code or F-code cross section, and a reflective sequin with a reflectivity of ≥85% is pasted on the inside of the slot; The edge of the image layer 4 is inserted from one side of the image slot 7 and slides along the slot until it completely covers the lightbox layer. The edges of the images of adjacent lightboxes can be tightly joined, avoiding image wrinkles or splicing misalignment caused by traditional adhesive fixing. The reflective sequins can reflect the scattered light from the light-emitting layer and direct the light to the image layer 4, increasing the brightness of the image by 15%-20%. At the same time, they can compensate for the slight brightness differences that may occur between the LED light strips 6, such as increasing the brightness at the gaps between the light strips to more than 95% of the adjacent areas, ensuring that the overall color display of the image is uniform. H-code or F-code screen slot 7 facilitates screen replacement without removing the lightbox layer.

[0022] Metal fixing frame 8, such as angle steel, is welded to the inner side of the light box layer. Both the fixing frame 8 and the bottom plate of the light-emitting layer 9 are through holes with a diameter of 8-10mm. After the expansion bolts pass through the through holes, they are fixed to the inner wall of the cube frame. Expansion bolts rigidly connect the light box layer, the light-emitting layer, and the frame to prevent equipment vibration. If the user moves around, the light box layer may shift or the LED light strip 6 may become misaligned, ensuring that the lighting position accurately corresponds to the image layer 4 after long-term use.

[0023] Light openings 5 ​​are evenly distributed along the length of the frame of the light box layer, and LED light strips 6 pass through the light openings 5 ​​and are fixed to the bottom plate 9 of the light-emitting layer; The lamp holder 5 restricts the radial displacement of the LED strip 6 to ensure uniform spacing between the strips and prevent uneven lighting (such as local bright spots) caused by the sliding of the strips. The light strip can be quickly inserted / removed from the outside of the light socket 5, allowing for replacement of faulty light strips without disassembling the light box layer.

[0024] The high light transmittance of acrylic allows the support column 10 to almost blend into the picture. When users look at the ground or side from the viewing platform, there are no obvious visual breaks obstructed by the support column 10, ensuring the integrity of the panoramic picture. UV inkjet printing cloth features high color fidelity, color gamut coverage of ≥90%, strong light resistance, no fading after 6 months of outdoor exposure, good flexibility, and can fit the curvature of curved light boxes 11. It can accurately present still frame panoramic images and avoid color deviation or image wrinkles that would damage the immersive experience. The flexibility of the UV inkjet printing cloth is compatible with the curved / rectangular structure of the lightbox layer, allowing it to fit tightly against the surface of the lightbox layer without bubbles.

[0025] Detailed Workflow Phase 1: Equipment Assembly Step 1: Assemble the rounded corner frame of the cube The frame is made of a cube with rounded corners, and the material is stainless steel / aluminum alloy. It ensures that the dimensions of the frame’s 6 planes, 12 rounded corner edges and 8 intersections are accurate, and provides access for users. Check the flatness of the inner wall of the frame to avoid the light box layers not being able to fit tightly.

[0026] Step 2: Installation and fixing of the light box layer Install light boxes in sections according to the frame structure: Rectangular lightbox 2: It is fixed to the inner walls of the frame on 6 planes with screws, ensuring that the edges of the lightbox are aligned with the edges of the frame; Curved lightbox 11: Fits the 12 rounded corner edges of the frame and is spliced ​​to the rectangular lightbox 2 by snap-fit; Arc-shaped triangular light box 12: The 8 intersections of the connecting frame are fixed to the adjacent light boxes with screws; A metal fixing frame 8 is welded to the inside of the light box layer, and the fixing frame 8 is rigidly connected to the inner wall of the frame with expansion bolts to ensure that the light box layer does not shake. Light openings 5 ​​are made in the frame of the light box layer, with the light openings 5 ​​facing inwards to ensure that the LED light strips 6 can be accurately embedded.

[0027] Step 3: Install the light-emitting layer The LED light strips 6 are evenly fixed to the base plate 9, and designed with a 120° light emission angle of the LED light strips 6 to ensure overlapping light without dark areas. Connect the base plate 9 to the fixing frame 8 of the light box layer using expansion bolts to ensure that the LED light strip 6 passes through the light opening 5 of the light box layer; Power-on test of the light-emitting layer: Use an illuminance meter to test the brightness of each area inside the light box layer to ensure that the brightness is ≥300 lux. If there are dark areas, adjust the position of the light strips or increase the number of light strips.

[0028] Step 4: Installation of the viewing platform Four to six acrylic support columns 10 are evenly arranged in the central area at the bottom of the frame, and the bottom of the support columns 10 is screwed to the bottom of the frame. Tempered glass 3 is placed over the top of the support column 10. The levelness of the glass is checked with a level and a load-bearing test is performed. If a 50kg weight is placed, the glass does not deform significantly.

[0029] Phase Two: Screen Installation and Display Debugging Step 1: Clipping and Installing Image Layer 4 Cut the UV inkjet fabric image according to the dimensions of each lightbox (rectangular / arc / arc-triangular), leaving a 1-2cm margin at the edge of the image for inserting the card slot; Insert the cropped image into the H / F code image slot 7 of the lightbox layer, slide it along the slot until it completely covers the surface of the lightbox layer, and ensure that the edges of the images of adjacent lightboxes are aligned without wrinkles or bubbles. Check the integrity of the image coverage: Ensure that there are no exposed areas on the inner wall of the frame, and that there are no breaks in the image at rounded corners and intersections.

[0030] Step 2: Adjusting the lighting and visual effects Power on the light-emitting layer and adjust the brightness of LED strip 6, such as 80% during the day and 50% at night. Observe whether the color display of layer 4 is uniform and compare it with the design draft. The color deviation should be ≤ΔE762.0. Standing in the center of the viewing platform, simulate the user's perspective and check for any image breaks or uneven brightness in the 360° horizontal field of view and the 180° vertical field of view. If any problems are found, adjust the brightness of the light strips or realign the image. Screen stability test: Slight shaking of the frame did not cause the screen to shift; after 24 hours of continuous operation, the screen did not fade or decrease in brightness.

[0031] Phase Three: Immersive Viewing for Users Step 1: User Entry and Location Users enter the viewing platform through the reserved passage in the frame and stand in the center of the platform. At this time, the user's eyes are level with the center of the image layer 4, and the field of vision is unobstructed.

[0032] Step 2: Naked-eye immersive experience The luminescent layer continuously provides uniform light source to the image layer 4. The still panoramic image presented by the UV inkjet cloth, such as starry sky, forest, city panorama, etc., surrounds the user 360°. There is no image break in the horizontal direction and the vertical direction is covered from the ground to the top of the frame. Users can freely rotate their viewing angle. Because the screen has no gaps, uniform brightness, and is in an immersive environment, users can achieve a naked-eye immersive experience without the need for auxiliary equipment. The visual focus can be switched to any direction of the screen without visual fatigue.

[0033] Phase 4: Equipment Maintenance and Screen Update Step 1: Change the screen Power off the light-emitting layer and pull out the old image from one side of the light box layer slot; Install the newly cut UV inkjet canvas image according to step 1 of the second stage, and realign the edges; Test the color rendering of the new screen after powering it on to ensure there are no deviations.

[0034] Step 2: Maintenance of the light-emitting layer If LED strip 6 malfunctions and is dimly lit or not lit at all, after powering off, remove the faulty LED strip 6 from lamp port 5 and insert a new LED strip 6 of the same model. Clean the dust on the base plate 9 and LED light strip 6 every 3 months and blow it off with compressed air to prevent dust from blocking the light. Check the LED strip driver power supply, such as a 12V DC power supply, to ensure that the voltage is stable and to avoid voltage fluctuations damaging the LED strip.

[0035] Step 3: Framework and Platform Maintenance Check the fixing bolts of the frame and light box layer every 6 months, and tighten them if they are loose. Clean the surface of the tempered glass 3 with a neutral detergent to prevent stains from affecting the viewing of the ground image; Inspect the acrylic support column 10. Replace it promptly if there are scratches or damage to ensure stable support.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
