For integrators and terminal procurement55 inch splicing screenProject plan: in the video and image-based display scene, the visual integrity of the 0.88mm scheme is used to save about 15-20% of the splicing unit budget. One-stop delivery of selection, signal, bracket, installation, calibration and acceptance.
More complete than 3.5mm, save 15-20% splicing unit cost than 0.88mm
Corporate lobby/showroom/conference room/commercial space
Selection → signal scheme → bracket → installation → calibration → acceptance
RS232 LAN centralized control, compatible with mainstream splicing processor
SelectLCD splicing screenSet the seam first.Ultra-narrow side splicing screen0.88mm, 1.7mm and 3.5mm respectively correspond to different viewing distances and content types -1.7mm is not a compromise, but the optimal solution for 2-4 m viewing and video images. The table below helps you quickly locate.
| Comparison dimension | 0.88mm patchwork | 1.7mm patchwork (recommended) | 3.5mm patchwork |
|---|---|---|---|
| visual continuity | Extremely high, close to integration | Higher, balanced scheme | Medium |
| Cross-screen text/chart | Very suitable | Suitable | Basically available |
| Maps/Drawings/Dashboard | Recommendation | Optional | Depending on the content |
| Corporate showroom/high-end lobby | Recommendation | Recommendation | Suitable for ordinary display |
| Commercial Space/Advertising | Optional | Recommendation | Suitable for long-distance viewing |
| Project budget | Higher | Medium (15-20% more than 0.88mm) | Lower |
| Recommended viewing distance | Close to Medium Distance | 2-4 m | More than 3 meters more appropriate |
We don't write "zero patchwork" "completely seamless". There is a physical border on the LCD splicing screen. Only by clearly spelling out the parameters can we help you make the right selection-this is also our rightProcurement of splicing screenThe basic attitude of the project.
Refers to the splicing of two adjacent screensBilateral general patchwork, the unilateral border is about 0.85mm. This is the physical parameters of the panel itself, the industry common nominal caliber.
About 1-2mm optical space should be reserved between the screen and the screen during installation,The actual patchwork seam is about 2.5mm. This is not a quality problem, but the necessary process spacing to protect the screen and prevent thermal expansion and extrusion.
Compared with the 3.5mm scheme, the visual cutting sense of cross-screen video, image and data is significantly reduced. At a viewing distance of 2-4 meters, the actual seam of 2.5mm is almost imperceptible.
| Patchwork grade | physical patchwork | Actual patchwork (including process spacing) | Recommended viewing distance | Applicable content |
|---|---|---|---|---|
| 0.88mm | 0.88mm | Approximately 1.9mm | More than 1.5m | Maps/Dashboard/Text/Drawings |
| 1.7mm | 1.7mm | About 2.5mm | 2-4 m | Video/Image/Brand Content |
| 3.5mm | 3.5mm | Approximately 5mm | More than 3m | Video/Advertising/Remote Display |
The first question most often asked by integrators and terminal buyers is "which seam should I choose for my scene". This oneSelection of splicing screenThe comparison table and the distance-content matrix are determined.Meeting room splicing screen, exhibition hall splicing screen, monitoring splicing screenThe first step of the layout.
| Project conditions | Recommended patchwork | Reason |
|---|---|---|
| Viewing distance <2 meters, mainly data/text | 0.88mm | Close-range lower patchwork has obvious influence, and ultra-narrow patchwork is required. |
| Viewing distance 2-4 meters, mainly video/image | 1.7mm | Balance Point, Visual Integrity and Budget |
| Viewing distance> 4 meters, mainly advertising/video | 3.5mm | Low perception of long-distance lower patchwork and optimal budget |
| Adequate budget calls for "near-seamless" | 0.88mm | Command Center/High-end Exhibition Hall C |
| Budget sensitive, but requires picture integrity | 1.7mm | The price-performance option for large-scale deployment |
| Corporate lobby/showroom/conference room | 1.7mm | Medium viewing distance, mixed video/graphic |
| Commercial complex/hotel information release | 1.7mm | Intensive areas, requiring some visual integrity |
| Security Monitoring/Command Center | 0.88mm | Data-intensive, high cross-screen continuity requirements |
Don't just look at the unit price of a single screen when buying a splicing screen. Let's take a 3 × 3 splicing wall (9 55-inch units) as an example and compare the 5-year total cost of ownership (TCO) of the 0.88mm / 1.7mm / 3.5mm scheme-taking into account units, brackets, processors, energy consumption and maintenance.
| Cost Module | 0.88mm scheme | 1.7mm scheme (recommended) | 3.5mm scheme |
|---|---|---|---|
| Splicing unit (9 units) | ¥ 72,000 (baseline) | ¥59,400（-17.5%） | ¥43,200（-40%） |
| Support and installation | 12,000 Precision Trim Bracket | ¥ 9,000 Precision Trim Bracket | ¥ 5,000 Standard Bracket |
| Video wall processor | ¥ 28,000 to match high bandwidth | 15,000 to be matched with belt load | 10,000 basic type is enough |
| 5-year energy consumption (estimated) | Approximately 56,800 | Approximately 56,800 | Approximately 56,800 |
| 5 years maintenance/spare parts | 2,000 (industrial grade) | 2,000 (industrial grade) | 2,000 (industrial grade) |
| Total 5-year TCO | ¥ 170,800 (REF) | ¥142,200（-16.7%） | ¥117,000（-31.5%） |
Calculation caliber: 3 × 3, 9 55-inch units; The unit price is estimated according to the median value of the mainstream quotation interval in the open market (0.88mm about 8,000/set, 1.7mm about 6,600/set, 3.5mm about 4,800/set, for reference only, subject to the actual quotation of the project); Energy consumption is estimated according to the typical power consumption of 180W for a single screen, 24/7 continuous operation, and the industrial electricity price is about 0.8/kWh, the power consumption of the three schemes is similar, and the processor is estimated according to the load and bandwidth requirements. The actual cost varies with the panel brand, brightness version, layout and construction conditions.
The 55-inch splicing screen can be seen clearly and for a long time, relying on the panel and driving details. Single-screen FHD, optional brightness, wide viewing angle, anti-glare-selecting brightness according to ambient light is the first step for commercial display solutions without errors.
Single screen 1920 × 1080 native resolution; The total physical pixels are 3840 × 2160(4K) after 2 × 2 splicing and 7680 × 4320 after 4 × 4 splicing. The display effect depends on the load capacity of the signal source and the splicing controller.
500nits is suitable for conference rooms, exhibition halls and corporate lobbies. 700nits is suitable for strong light environments such as glass curtain wall lobbies and bright commercial spaces. The picture is not gray or white.
The moving line of the exhibition hall and the passenger flow area of the lobby are still stable, and the moving line of business negotiation and visit is not restricted by the air space.
Reduce the interference of environmental reflection, improve the visibility and picture transparency of fluorescent lamp and spotlight environment.

The above are the typical public parameters of the 55-inch 1.7mm splicing screen, subject to the technical specification of the corresponding model.
The narrower the joint, the higher the installation accuracy requirements. The 1.7mm splicing screen needs to be calibrated block by block with a fine-tuning bracket to ensure uniform horizontal and vertical gaps-this is why we insist on on-site installation by the project team.
Support up and down/left and right/front and back multi-dimensional fine-tuning,Precision control of flat-laid seam ± 0.5mmTo ensure that the whole wall gap is unified and the picture is even.
The hydraulic support realizes pre-maintenance and is suitable for embedded lobbies and narrow equipment rooms. During installation, optical space is reserved between the screens to avoid scratching the screen when popping up.
