Have you found LED screens hidden in these places?
Two days ago, when I was shopping in the mall, my friend suddenly pointed to the ceiling and asked, "How can the top of the starry sky move? " After closer, I found out that it was P4 pitch LED screen Camouflage decorative top. Display screens today are no longer just advertising boards - they may be hidden in the floor tiles under your feet, or the glass curtain walls that turn into malls.
Five high-frequency application scenarios
-
Commercial complex:
- Arc screen of the atrium (radius of curvature ≥8 meters)
- Elevator hall poster screen (automatic brightness adjustment 800-1200cd/m²)
- Brand window transparent screen (light transmittance 86% does not affect lighting)
-
Transportation hub:
- Subway station information screen (IP65 waterproof and dustproof)
- Airport flight dynamic screen (supports 7×24 hours continuous operation)
- Bus station weather forecast screen (Wide temperature operation from -30℃ to 60℃)
Comparison of key points of indoor and outdoor installation
| Indoor environment | Outdoor environment |
|---|
| Brightness requirements | 800-1500cd/m² | 4000-7500cd/m² |
| Protection level | IP43 | IP65 |
| Maintenance cycle | 18 months | 6 months |
| Power supply configuration | 220V civilian electricity | 380V industrial electricity |
Special scenario installation case
- Stage performance : A music festival uses floor tiled screen + column screen combination to achieve 270° immersive visual effect
- Stadium : The basketball court fence screen is only 1.5 meters away from the auditorium, and it remains glare-free
- Commercial Exhibition Hall : The mirror screen at the reception desk is a decorative mirror during the day, and the information screen is transformed at night.
Installation restrictions you may be overlooking
- Strong electromagnetic interference zone:
Electromagnetic shielding needs to be installed within 30 meters of the transformer (a project has caused screen loss due to ignoring this point)
- Extreme temperature and humidity environment:
Car wash room installation must be equipped with a constant temperature box (internal temperature fluctuation ≤±3℃)
- Areas with frequent vibrations:
Seismic support should be used around the amusement facilities (the amplitude is controlled within 0.02mm)
If you ask me, selecting the display position is like finding a partner—— Appropriate is more important than expensive . The smartest solution I have ever seen is that the convenience store freezer door is embedded with a transparent screen, which not only displays promotional information but does not affect pickup. Next time you go shopping, you might as well pay more attention. Maybe you will encounter a wonderful combination of technology and art at the corner.
