Description

Technical Field

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

[0002] With the development of digital display technology, immersive visual experiences are widely used in museums, science and technology museums, commercial spaces, and themed exhibitions. Traditional display methods mostly use flat screens or projection systems, which have problems such as limited viewing angles, fragmented images, and weak immersion, making it difficult to meet users' needs for realistic scene reproduction and all-round visual immersion.

[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

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a semi-cube panoramic digital RVR naked-eye still frame immersive display device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: The semi-cubic panoramic digital RVR naked-eye still-frame immersive display device of this utility model includes:

[0008] A semi-cube hollow frame, the inner wall of which is covered with a lightbox image;

[0009] A display layer is disposed on the surface of the lightbox display, and the lightbox display has a display slot. The edge of the display layer is fixed by the display slot.

[0010] The light-emitting layer is located on the inner side of the lightbox image and includes a base plate and LED light strips evenly arranged on the base plate.

[0011] The viewing platform includes tempered glass and support columns supporting the tempered glass. The support columns are distributed at the bottom center of a semi-cubic hollow frame. The tempered glass is installed on the top of the support columns and covers the ground portion of the lightbox image.

[0012] Preferably, the lightbox image adopts a rectangular frame structure, and the image slot is set at the edge of the lightbox image. The image slot adopts an H code or F code structure.

[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 semi-cubic panoramic digital RVR naked-eye still-frame immersive display device, comprising:

[0029] A semi-cube hollow frame 1, the inner wall of which is covered with a lightbox image 2;

[0030] The image layer 4 is disposed on the surface of the lightbox image 2. The lightbox image 2 is provided with an image slot 7, and the edge of the image layer 4 is fixed by the image slot 7.

[0031] The light-emitting layer is located on the inner side of the lightbox screen 2, and includes a base plate 9 and LED light strips 6 evenly arranged on the base plate 9;

[0032] The viewing platform includes tempered glass 3 and support columns 10 supporting the tempered glass 3. The support columns 10 are distributed at the bottom center of the semi-cubic hollow frame 1. The tempered glass 3 is installed on the top of the support columns 10 and covers the ground part of the lightbox screen 2.

[0033] This technical solution achieves a 720-degree immersive still-frame display without glasses through a core mechanism of "enclosed space construction - layered display collaboration - light and shadow fusion adaptation". The core logic is as follows: a semi-cubic hollow frame 1 serves as the supporting base, with its inner walls covered by lightbox images 2 forming an enclosed six-sided display space (ground and four walls); the image layer 4 (UV-printed fabric) is fixed to the surface of the lightbox image 2 via image slots 7, presenting panoramic still-frame content; the LED light strips 6 of the inner light-emitting layer are evenly illuminated by the base plate 9, ensuring consistent image brightness; the tempered glass 3 of the viewing platform provides a place for users to stand, while the acrylic support columns 10 bear the weight while avoiding obstruction of the ground image; reflective glitter in the image slots 7 eliminates splicing shadows, and the fixing frame 8 and expansion bolts ensure overall structural stability. Ultimately, the six-sided images form a surround visual enclosure within the enclosed space, allowing users to enjoy a 720-degree immersive experience without wearing any devices.

[0034] Semi-cube hollow frame 1 and lightbox image 2

[0035] Structural Coordination: The semi-cube hollow frame 1 is constructed of metal, and the inner wall is covered with a rectangular frame structure lightbox screen 2. The length of the rectangular frame edges is designed according to the needs of the scene to ensure that there are no blind spots in the user's view.

[0036] Working principle: The lightbox image 2 is fixed to the inner wall of the semi-cube hollow frame 1 by the fixing bracket 8 and expansion bolts (through the fixing bracket 8), providing stable support for the image layer 4 and the light-emitting layer, and ensuring the integrity of the image coverage.

[0037] Image layer 4 and image slot 7 (H code / F code)

[0038] Image Layer 4 Fixing Mechanism: Image Layer 4 uses UV inkjet fabric (resolution ≥ 300dpi), and its edges are inserted into the H-code or F-code slots on the frame of the lightbox image 2. The H-code / F-code is an industry standard profile with a "groove" shaped cross-section. The groove width is adapted to the thickness of the UV inkjet fabric (usually 0.5-1mm). The elastic clamping force of the slots tightly fixes the image edges to prevent loosening or warping, or it is fixed to the frame of the lightbox image 2 by clips and screws to ensure the installation stability of the slots themselves.

[0039] The function of reflective sequins: Reflective sequins (made of highly reflective metal or PET film) are embedded in the picture slot 7. When the LED light strip 6 is lit, the sequins reflect the light to the picture splicing seam, eliminating the shadows caused by uneven illumination of the light strip and ensuring a natural transition between adjacent pictures (sponging visual error ≤1mm).

[0040] Light-emitting layer (9 base plates + 6 LED light strips)

[0041] Uniform lighting principle: The base plate 9 is made of PVC, aluminum composite panel or acrylic material (white matte finish). The LED light strips 6 are installed through the light openings 5 ​​on the frame of the lightbox picture 2 and are evenly arranged along the base plate 9. After the LED light strips 6 emit light, the light is diffusely reflected by the base plate 9, so that the brightness of the picture layer 4 is uniform (brightness deviation ≤5%), avoiding local over-brightness or under-brightness that affects the visual experience.

[0042] LED strip fixing method: The LED strip is pasted on the base plate 9. The base plate 9 is fixed to the inner wall of the semi-cube hollow frame 1 by expansion bolts (through the base plate 9). The lamp opening 5 and the LED strip 6 are fitted with a clearance. The two ends of the LED strip are connected to the power supply through wires to ensure that the LED strip does not wobble in the lamp opening 5 and will not shift due to vibration during long-term use.

[0043] Viewing platform (3 tempered glass panels + 10 acrylic support columns)

[0044] Balance between load-bearing capacity and light transmission: Tempered glass 3 covers the ground portion of the lightbox image 2, providing a place for the user to stand without obstructing the image content. Acrylic support columns 10 are evenly distributed below the tempered glass 3 (usually 4-6 in a rectangular arrangement), utilizing the high strength of acrylic to support the weight of the glass and the user.

[0045] Anti-interference design: The bottom of the support column 10 is isolated from the ground part of the light box screen 2 by a silicone pad to avoid hard contact that could cause screen abrasion; the tempered glass 3 is covered with an anti-glare coating to reduce the interference of LED light strip 6 reflections on screen viewing.

[0046] Detailed Workflow

[0047] Equipment installation phase (1-2 days)

[0048] Step 1: Frame and Fixture Assembly

[0049] ① Assemble the semi-cube hollow frame 1, ensuring that the perpendicularity deviation of the six sides is ≤2mm;

[0050] ② Fix the rectangular frame of the lightbox image 2 to the inner wall of the frame, and adjust its position using the fixing bracket 8 so that the image border fits the frame;

[0051] ③ Drive the expansion bolts through to the fixing frame 8 and into the ground / wall, and tighten the bolts to make the frame rigidly connected to the building structure.

[0052] Step 2: Install the light-emitting layer

[0053] ① Install the base plate 9 inside the lightbox image 2 (fixed with screws or adhesive), ensuring that the surface of the base plate 9 is flat;

[0054] ② Pass the LED light strips 6 through the light openings 5 ​​on the border of the lightbox image 2 and arrange them evenly along the vertical direction of the base plate 9. The spacing between the light strips is set according to the size of the image (usually 8cm).

[0055] ③ Connect the LED strip wires to the power supply, test the brightness uniformity after powering on, and adjust the position of the LED strip to eliminate dark areas.

[0056] Step 3: Fix the image layer 4 to the card slot

[0057] ① Cover the surface of the lightbox image 2 with a UV inkjet cloth (pre-printed with a panoramic still image), aligning the edges of the image with the lightbox frame;

[0058] ② Insert the edge of the image into the groove of the H-code / F-code card slot, and press along the length of the slot to make the image fit snugly;

[0059] ③ Embed reflective sequins in the slots at the seams of the images to ensure that the sequins completely cover the shadow area of ​​the seams.

[0060] Step 4: Building the viewing platform

[0061] ① Mark the position of the support column 10 at the center of the bottom of the semi-cube frame (in a rectangular distribution), place the acrylic support column 10 and fix it (by gluing or screwing the bottom).

[0062] ② Place the tempered glass 3 stably on top of the support column 10, adjust the level, and ensure that the edge of the glass is aligned with the ground image.

[0063] Operation and maintenance phase

[0064] Step 1: Start the device

[0065] ① Connect the LED strip 6 to the power supply (usually AC power) and adjust the brightness (usually 500-800 cd / m²). 2 This allows for realistic color reproduction in the image;

[0066] ② Check if there are shadows at the splicing points of the images. If so, fine-tune the position of the reflective glitter until the shadows are eliminated.

[0067] ③ The user stands in the center of the tempered glass 3 and gets a 720-degree naked-eye immersive experience through the six-sided surround screen.

[0068] Step 2: Routine Maintenance

[0069] ① Regularly (monthly) check whether the image layer 4 is loose. If it is found to be warped, reinsert it into the slot and press it to fix it.

[0070] ② Clean dust from the surface of image layer 4 (quarterly) to ensure luminous efficiency;

[0071] ③ Check whether the connection between the tempered glass 3 and the support column 10 is secure, and tighten it in time if it is loose.

[0072] Screen replacement process (as needed)

[0073] ① Disconnect the power supply to LED light strip 6 and pull out the old UV inkjet cloth from the image card slot 7;

[0074] ② Insert the edge of the new image into the slot and fix it in place as described in step 3 of the installation process;

[0075] ③ Power on the device to check the splicing and brightness of the new image, and adjust the reflective glitter if necessary.
