[0002] With the continuous development of digital display technology and the demand for immersive experiences, traditional flat-panel displays can no longer meet users' requirements for panoramic and stereoscopic visual experiences. To provide more realistic visual effects and a deeper sense of immersion, various solutions have emerged in the market, including virtual reality (VR) and augmented reality (AR) devices. However, these solutions typically require wearing specialized hardware, such as VR glasses or headsets, which not only increases the user's cost but may also cause discomfort due to prolonged wear.

[0003] Currently, some immersive display devices on the market adopt circular, dome, or multi-screen splicing formats, but they generally suffer from drawbacks such as complex structures, difficult installation, high maintenance costs, and insufficient brightness and contrast. Furthermore, most devices still rely on glasses or other auxiliary equipment to achieve stereoscopic visual effects, limiting user freedom and experience comfort. In addition, regarding static content display, the lack of efficient lighting and reflection design results in weak image layering, poor detail, and a negative impact on overall visual impact. The fixing methods for lightbox images often rely on adhesives or frame pressing, which easily leads to image warping, cumbersome replacement, and a lack of optimized design for light reflection and brightness. An unreasonable LED light source layout can easily cause uneven lighting, dark areas, or glare. Utility Model Content

[0015] 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.

[0016] Please see Figure 1-6 The present invention relates to a semi-cubic rounded corner still frame panoramic digital RVR naked-eye immersive display device, comprising: A semi-cube rounded corner frame 1, the inner wall of which is covered with a light box layer, the light box layer including a rectangular light box 2, an arc-shaped light box 11 and an arc-shaped triangular light box 12, the rectangular light box 2 being arranged on the inner wall of the semi-cube rounded corner frame 1, the arc-shaped light box 11 being arranged at the rounded corner structure of the semi-cube rounded corner frame 1, and the arc-shaped triangular light box 12 being arranged at the intersection of multiple rounded corner structures of the semi-cube rounded corner frame 1; The image layer 4 is disposed on the surface of the light box layer. The rectangular light box 2, the arc light box 11 and the arc-shaped triangular light box 12 are all provided with image slots 7 on their sides. The edge of the image layer 4 is fixed by the image slots 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 semi-cube rounded corner frame 1.

[0017] This technical solution achieves a naked-eye 720-degree immersive still-frame display through core mechanisms such as enclosed space construction, layered display collaboration, and light and shadow fusion adaptation. Through structural adaptation, uniform illumination, and panoramic image coverage, it allows users to experience an immersive visual experience surrounded by the image without the need for auxiliary devices such as VR glasses. The specific principles are as follows: The inner wall is covered with a lightbox layer. The rectangular lightbox 2 is adapted to the flat inner wall of the frame, such as the front, back, left, right, top and bottom six sides. The arc lightbox 11 is adapted to the rounded corner structure of the frame to avoid the image breaking at the corner. The arc-shaped triangular lightbox 12 is adapted to the intersection of multiple rounded corners, such as the corner connecting the top and the side. The three are spliced ​​together to form a panoramic inner wall without visual breaks, providing a continuous load-bearing foundation for the image layer 4. Light-emitting layer: The evenly arranged LED light strips 6 provide a stable surface light source without dark areas, and the light shines evenly on the inside of the light box layer to ensure that the picture layer 4 has full color rendering; Lightbox layer: As a transitional carrier between the light-emitting layer and the image layer 4, its rectangular / arc / arc triangular structure adapts to the frame shape, while the image layer 4 is fixed by the image slot 7 of the frame to prevent the image from shifting or wrinkling. Image layer 4: Covers the surface of the light box layer, and presents still images such as panoramic landscapes and digital art through the uniform lighting of the light-emitting layer. The enclosed structure of the semi-cube rounded corner frame 1 allows the image to cover the user 720°, 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 semi-cube rounded corner frame 1. When users stand / stay on it, they are in the center of the screen layer 4, with no blind spots, no horizontal screen breaks, and vertical coverage from the ground to the top of the frame. Furthermore, the design of the tempered glass 3 and acrylic support columns 10 does not obstruct the screen, further enhancing the immersive and enveloping experience.

[0018] The light-emitting layer consists of a rigid base plate 9, such as an aluminum alloy plate, and LED light strips 6. The light strips are evenly arranged along the length / width direction of the base plate 9. The power of the light strips is consistent, such as 0.5W / LED, and the color temperature is 5000K-6500K cool white light. The spacing between the light strips is designed according to the light emission angle of the light strips, such as 120°. The illumination range of adjacent light strips overlaps to avoid dark areas and ensure that the colors of each area of ​​the image layer 4 are uniform, without bright spots / dark spots that would disrupt the immersive experience. The rigid base plate 9 provides a fixed carrier for the light strip, preventing the light strip from shifting and causing uneven lighting. At the same time, the aluminum alloy base plate 9 can help dissipate heat from the light strip and extend its lifespan. The LED light strip 6 supports PWM dimming with a brightness range of 10%-100%, which can be adjusted according to the ambient light intensity. For example, it can be adjusted to 80% during the day and 50% at night to ensure image clarity while avoiding glare.

[0019] The viewing platform consists of tempered glass 3 and acrylic support columns 10. The support columns 10 are evenly distributed, such as 4 columns, located below the four corners of the glass. The tempered glass 3 covers the ground area of ​​the light box layer at the bottom of the frame. The high strength of tempered glass 3 allows multiple people to stand on it at the same time, such as 2-3 people, and when broken, it breaks into blunt-angled particles, posing no safety hazard. The acrylic support column 10 is made of a highly transparent material, which will not block the image of the ground lightbox layer. Users can see the ground image when they are standing, achieving full visual coverage in all directions. The height of the support column 10 is designed so that the user's eyes are level with the center of the screen layer 4 when standing. For example, the platform height is 12cm, which is suitable for users with an average height of 160-180cm, ensuring that the center of vision is aligned with the core area of ​​the screen and optimizing the immersive experience.

[0020] The lightbox layer is a lightweight rectangular frame made of materials such as aluminum alloy. The frame has H-code or F-code image slots 7, and reflective sequins are pasted on the inside of the slots. The H / F code slot has a side-insertion structure. The edge of the image layer 4 can be inserted from one side of the slot and slid along the slot until it completely covers the light box layer. This structure not only avoids damage caused by image pasting, but also allows the image edges of adjacent light boxes to be tightly connected, achieving a seamless panoramic image. 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% and compensating for the slight brightness differences that may occur between the light strips, ensuring that the overall color rendering of the image is uniform. The aluminum alloy frame is not easily deformed, which can maintain the precise position of the slot for a long time and prevent the image from wrinkling due to frame deformation.

[0021] Metal fixing bracket 8 is welded or screwed to the inside of the light box layer. Both the fixing bracket 8 and the bottom plate 9 of the light-emitting layer pass through through holes adapted to expansion bolts. After the expansion bolts pass through the through holes, they are fixed to the inner wall of the semi-cube frame. The base plate 9 is rigidly connected to the fixing frame 8 by expansion bolts to prevent the light-emitting layer from shifting due to vibration, such as when the user walks around, thus ensuring the stability of the illumination position.

[0022] Light openings 5 ​​are evenly distributed along the length of the frame of the light box, and LED light strips 6 pass through the light openings 5 ​​at both ends or in the middle. The light strips are embedded into the frame of the light box layer through the light port 5 to prevent the light strips from shifting on the base plate 9. If they slide, the spacing will be uneven, ensuring that the light-emitting area of ​​each light strip accurately corresponds to the image area of ​​the light box layer. U-shaped lamp holder 5 allows the LED strip to be quickly inserted from the outside, enabling replacement of faulty LED strips without disassembling the lamp housing layer. For example, the old LED strip can be pulled out from lamp holder 5 and a new LED strip can be inserted: The light outlet 5 faces the inside of the light box layer, guiding the LED light to concentrate on the light box layer, reducing light leakage to the outside of the frame, and improving light utilization efficiency.

[0023] The image layer 4 is made of UV inkjet cloth, and the support column 10 is made of transparent acrylic material; UV inkjet printing cloth features high color fidelity, color gamut coverage of ≥90%, strong light resistance, no obvious fading after 6 months of outdoor exposure, good flexibility, and can adapt to the curvature of curved light boxes 11. It can accurately present still frame panoramic images and avoid color deviation that would damage the immersive experience. The transparent acrylic support column 10 hardly obstructs the view of the ground or the light box below. When users look down at the ground from the viewing platform, there are no obvious visual breaks caused by the support column 10, ensuring the integrity of the panoramic view. 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 or wrinkles, further enhancing the immersive experience of the image.

[0024] Detailed Workflow Phase 1: Equipment Assembly Step 1: Assemble the semi-cube rounded corner frame 1 Assemble a semi-cube rounded corner frame 1 to ensure that the inner wall of the frame, the rounded corner structure, and the intersection of multiple rounded corners, such as the top corner, are accurately sized to avoid incompatibility with the subsequent lightbox layer; Check the semi-open areas of the frame, such as the size of the side openings, to ensure that users can enter normally, while reserving space at the bottom of the frame for the installation of a viewing platform.

[0025] Step 2: Installation and fixing of the light box layer Install rectangular light boxes 2, arc-shaped light boxes 11 and arc-shaped triangular light boxes 12 according to the frame structure: rectangular light boxes 2 are fixed to the inner wall of the frame plane, arc-shaped light boxes 11 fit the rounded corner structure, and arc-shaped triangular light boxes 12 are connected to the intersection of multiple rounded corners to ensure that the gap between the edges of adjacent light boxes is ≤0.2mm. A metal mounting bracket 8 is installed inside the light box layer. The mounting bracket 8 is rigidly connected to the inner wall of the frame by expansion bolts to ensure that the light box layer does not shake. Light openings 5 ​​are made on the frame of the light box layer, with the light openings 5 ​​facing inwards to ensure that the subsequent LED light strips 6 can be accurately embedded.

[0026] Step 3: Install the light-emitting layer Fix the LED light strips 6 evenly on the base plate 9 and connect the light strip driver power supply, such as a 12V DC power supply; Connect the base plate 9 to the fixing frame 8 of the light box layer using expansion bolts, and adjust the distance between the base plate 9 and the light box layer to 5-8mm to ensure that the light strip is facing the inside of the light box layer. Test the light-emitting layer by powering it on and use a lux meter to check the brightness of each area inside the light box layer to ensure that the brightness deviation is ≤5% and there are no dark areas; if there are dark areas, adjust the position of the light strips or increase the number of light strips.

[0027] Step 4: Installation of the viewing platform Four acrylic support columns 10 are evenly arranged in the center area at the bottom of the frame. The bottom of the support columns 10 is fixed to the bottom of the frame, such as by screws. Tempered glass 3 was placed on top of the support column 10, with the gap between the edge of the glass and the inner wall of the frame ≤1cm to ensure that the glass was level. In the load test, a 50kg weight was placed on the glass and there was no obvious deformation.

[0028] Phase Two: Screen Installation and Display Debugging Step 1: Clipping and Installing Image Layer 4 According to the dimensions of each lightbox layer, cut the UV inkjet fabric image into rectangles, arcs, or arc triangles, leaving a 1-2cm margin at the edge of the image for inserting the card slot; Insert the cut image into the H / F code slot on the lightbox layer, slide it along the slot until the image 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, ensuring there are no exposed areas on the inner wall of the frame, and no breaks in the image at rounded corners and intersections.

[0029] 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 whether the color is accurately reproduced. If compared with the design draft, the color deviation is ≤ΔE762.0. Standing in the center of the viewing platform, simulate the user's perspective and check for any image breaks or uneven brightness within the horizontal 360° and vertical 120° field of view; if any problems are found, adjust the brightness of the light strips or realign the image. Test the stability of the screen, such as by slightly shaking the frame, to ensure that the screen does not shift, and that the screen remains flat after long-term use.

[0030] Phase Three: Immersive Viewing for Users Step 1: User Entry and Location When a user enters the viewing platform and stands in the center, their eyes are aligned with the center of layer 4 of the screen.

[0031] Step 2: Naked-eye immersive experience The light-emitting layer continuously provides uniform light source to the image layer 4. The panoramic still frame image presented by the UV inkjet cloth, such as natural scenery and digital art scenes, surrounds the user, achieving 360° field of view coverage in the horizontal direction and vertical coverage from the ground to the top of the frame. Because the screen is seamless, the brightness is uniform, and the user is positioned at the center of the screen, they can have a naked-eye immersive experience without wearing VR devices. The visual focus can be freely switched to any direction of the screen without visual fatigue.

[0032] 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 slot in the light box layer; Install the newly cut UV inkjet canvas and realign the edges of the canvas; Test the display effect of the new screen after powering it on to ensure uniform color rendering.

[0033] Step 2: Maintenance of the light-emitting layer If a certain LED strip 6 malfunctions, such as being dimly lit or not lit at all, after powering off, pull out the malfunctioning LED strip 6 from the lamp opening 5 in the light box layer and insert a new LED strip 6. Regularly, such as every 3 months, clean the dust on the surface of the base plate 9 and LED light strip 6 to prevent dust from blocking the light and causing a decrease in brightness; Check the LED strip driver power supply to ensure stable voltage and avoid voltage fluctuations that could damage the LED strip.

[0034] Step 3: Framework and Platform Maintenance Regularly, such as every 6 months, check the fixing bolts of the frame and light box layer, and tighten them in time if they are loose. Clean the surface of the tempered glass 3 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.
