Key points for site selection of LED scrolling screen production base, how to choose core parameters

2025-12-10 199

​What are the power configuration standards for the production base? ​
Measured data in an industrial park in the Pearl River Delta shows that the rolling screen production line needs to meet the three-phase 380V ±5% voltage fluctuation range, and each thousand square meters of production capacity corresponds to a 500kVA transformer capacity. ​ ​It is recommended to choose a park equipped with a dual-circuit power supply system​ ​, so that in the event of a sudden power outage, the reflow soldering equipment can maintain a slow shutdown for 15 minutes, avoiding the loss of original parts worth 230,000 yuan/batch.


​Aluminum or steel for box structure? ​
Comparative test data reveals (36 months of outdoor use):

Deformation≤0.8mm/m²≥2.3mm/m²
Cooling efficiency38W/m·K16W/m·K
Salt spray test life3000 hours1200 hours
​Preferred 6 series aviation aluminum materials​​, combined with the dovetail splicing structure, the box splicing seams can be controlled within 0.1mm.

​What parameters should we pay attention to when selecting a driver IC? ​
The experience of a smart transportation project shows:

  • Scanning method: 1/16 scan saves 27% energy than 1/8 scan
  • Gray scale: 16bit has 4 times smoother color transition than 14bit
  • Refresh rate: ≥1920Hz can eliminate scanning lines during high-speed capture
    Focus on verification​ ​Temperature compensation function​ ​, in the -20℃ environment test, the color coordinate offset of the IC with compensation function Δu'v'≤0.003.

​How does the optical coating affect the display effect? ​
Comparison of three common membrane materials:

typetransmittanceAnti-UV indexViewing range
Ordinary diffusion film82%Level 3140°
Nanoprism film91%Level 5160°
microstructured membrane88%Level 7170°
​It is recommended to choose a composite film with anti-glare coating​​, so that the screen contrast can still maintain ≥5000:1 in a strong direct light environment.

Remember to bring a light meter during the on-site inspection - measure the brightness difference between the four corners and the center of the screen at a distance of 3 meters. High-quality products should be controlled within 15%. A municipal project ignored this detail, resulting in a 28% reduction in visual distance at night. Remember, real professional manufacturers will equip a dark room test area in the workshop and use standard color cards to demonstrate the color restoration process on-site. This process can best reveal the depth of technical strength.
