46 and 55 double size coverage-from small and medium control room to large command center, a brand full scene delivery
The wall width is 46 inches for 2m grade and 55 inches for 2.5m grade, which can be flexibly adapted according to the project conditions.
The single side is about 0.44mm, and the cross-screen map, data and monitoring picture are more continuous.
Type selection → signal scheme → bracket → installation → calibration → acceptance full process support
RS232 LAN centralized control, compatible with mainstream splicing processor and CMS platform
This is the core B2B selection tool on this page. The first question most often asked by integrators and end-point buyers is "46 or 55". Look at the core differences first, then take the seats according to the scene.
| Comparison dimension | 46 inches | 55 inches |
|---|---|---|
| Single-screen display area | About 0.58 ㎡(1019 × 574mm) | About 0.82 ㎡(1210 × 681mm) |
| Total width of 2 × 2 splicing | Approximately 2.04m | Approximately 2.42m |
| Total width of 3 × 3 splicing | Approximately 3.06m | Approximately 3.63m |
| Reference Unit Price Range (2025) | Others: about 7,500 yuan/fast Qunmao: about 5,xxx yuan/piece | Others: about 9,900 yuan/piece Qunmao: about 7,xxx yuan |
| Positioning | Supplementary Scheme for Space Constrained Scenarios | Industry mainstream standard scheme |
| Panel Source | BOE | LG / BOE |
| Project conditions | Recommended size | Reason |
|---|---|---|
| Wall width <2.5m,2 × 2 splicing | 46 inches | The total width is about 2.04m, leaving access for maintenance |
| Wall width> 3m,2 x 2 or 3 x 3 | 55 inches | The total width is 2.42m, and the visual impact is stronger |
| Budget sensitive but requires 0.88mm patchwork | 46 inches | The cost per unit is about 24% lower than 55 inches |
| Command Center/High-end Exhibition Hall/Exhibition Hall C | 55 inches | Industry standard size, large screen experience is better |
| Small and medium-sized meeting rooms/control rooms with limited space | 46 inches | 46 inches is exactly for the scene of "55 inches can't fit" |
Industry data show that operation and maintenance costs account for 60%-70% of the TCO of the splicing screen. Purchasing decision makers who focus only on the unit price of purchases will pay far more than expected within 5 years.
| Cost module (3 × 3 splicing wall · 9 sets) | 46 inches 3 x 3 | 55 inches 3 x 3 | Description |
|---|---|---|---|
| Splicing unit (9 units) | About 68000 yuan (benchmark) | About 89000 yuan (+ about 32%) | Calculated according to the reference unit price of 7,500 / 9,900 yuan/set |
| Video wall processor | Redundancy by total pixels x 1.2 | Redundancy by total pixels x 1.2 | Pixels with load = total screen pixels x 1.2 redundancy |
| Support and installation | Precision Trim Bracket | Precision Trim Bracket | 0.88mm requires high precision of bracket |
| 5-year energy consumption (estimated) | about 63000 yuan | about 95000 yuan | 55 inches power consumption is slightly higher |
| 5 years maintenance/spare parts | Low (industrial grade) | Low (industrial grade) | Modular design, single screen can be changed |
| 5 year TCO | Baseline | + about 20% ~ 25% | 55 inches higher total cost but better experience |
* Caliber Description: Energy consumption is estimated according to continuous operation at full load and commercial electricity price of about 0.8 yuan/degree (46 inches about 200W and 55 inches about 300W), which is actually subject to project configuration and local electricity price. The amount of splicing unit is calculated according to the reference unit price, only for comparison and reference, and the actual quotation is subject to the project configuration.
The average power consumption of the 55-inch splicing unit is about 300W, and the annual power consumption of a single unit for 24 hours is about 2,628 degrees. 46 inches is about 200W, and the annual power consumption of a single unit is about 1,752 degrees.
The average annual downtime of non-industrial splicing screens is about 8-15 hours. Industrial panels with modular design can minimize the downtime, and the failure of one screen will not affect the operation of the whole wall.
A 3 × 4 55 inch splicing wall project: the initial purchase of the cheap scheme is 480000 yuan, the 5-year operation and maintenance is 380000 yuan, and the total TCO is 860000 yuan; The initial 600000 yuan of the high-quality scheme is 180000 yuan for 5 years, and the total TCO is 780000 yuan-the high-quality scheme saves 80000 yuan in 5 years.
The purchase decision of 0.88mm splicing screen is not to compare the price of a single screen, but to calculate the total cost of ownership of the whole system for 5 years. Choose industrial-grade panels and modular design, is in for the next 5 years to save money.
The patchwork parameters directly affect the look and feel of cross-screen content. We make the true level of 0.88mm clear, allowing you to make the right choice by content type.
It means that the total double-sided patchwork seam of two adjacent screens is 0.88mm and the single-sided border is about 0.44mm. We don't write "zero patchwork", "completely seamless".
During installation, an optical space of about 1-2mm should be reserved between the screens (subject to passing through a piece of A4 paper smoothly), and the actual patchwork seam is about 1.9mm-this is not a quality problem, but a necessary process spacing to protect the screen.
Compared with the 3.5mm/1.8mm scheme, the visual cutting sense of cross-screen map, dashboard, GIS track and monitoring screen is significantly reduced. For a viewing distance of more than 3 meters, the actual seam of 1.9mm is almost negligible.
Text/Chart/Map/Dashboard → Recommended 0.88mm; Pure video/long-distance advertising → 1.8mm or 3.5mm, without paying for the stitching grade that is not needed.
| Patchwork grade | physical patchwork | Recommended viewing distance | Applicable content |
|---|---|---|---|
| 0.88mm | 0.88mm | More than 1.5m | Maps/Dashboard/Text/Drawings |
| 1.8mm | 1.8mm | More than 2.5m | Surveillance/Video/General Data |
| 3.5mm | 3.5mm | More than 3m | Video/Advertising/Remote Display |
The native resolution of a single screen is 1920 × 1080, and the total physical pixels after splicing can reach 4K or even 8K; The brightness is selected according to the ambient light conditions to avoid "indistinct" or "too dazzling".
1920 × 1080 native resolution; The total physical pixels are 3840 × 2160(4K) after 2 × 2 splicing and 7680 × 4320(8K) after 4 × 4 splicing.
500nits suitable for control room, conference room, indoor exhibition hall; 700nits suitable for glass curtain wall lobby, bright commercial space.
The control room operating seats and the side view of the conference space maintain stable color and brightness, and are visible from multiple angles.
Reduce environmental reflection interference, the picture is still clear and readable in strong light environment.
The narrower the seam, the higher the installation accuracy requirements. The 0.88mm splicing screen shall be calibrated block by block with a six-axis fine-tuning bracket, and the flat seam shall be monitored in real time with a feeler gauge to ensure that the horizontal and vertical gaps are completely unified.
Support up and down/left and right/front and back multi-dimensional fine adjustment, flat-splice precision control of ± 0.5mm, block-by-block calibration to ensure the unity of the gap.
Maintenance in front of hydraulic support, suitable for embedded lobby and narrow equipment room; optical space is reserved between screens during installation to avoid scratching the screen when popping up.
