Alas, recently several friends asked me how to buy LED grille screens? This thing looks simple, it’s just a lattice display! But if you really go around the market, you will be confused - the prices range from hundreds to tens of thousands per square meter, and the merchants are talking about "military-grade" and "imported chips" when running trains. Today we will break it apart and talk, and you will be sure to have the account in your heart after reading it!

​​1. Purchase misunderstanding: Why are there always people spending money in vain? ​ ​

​​Q: Where is the easiest thing to fall into when buying a grille screen? ​ ​
A: I have observed hundreds of procurement cases and found three typical pitfalls:

1. ​​Only look at the price and not the structure​​: Someone bought non-standard aluminum in cheap, but the box was deformed for half a year, and the repair fee was more expensive than the screen.
2. ​​Blindly pursue high brightness​​: The shopping mall must install an 8000cd/m² screen, and the customer will be sore after looking up for three seconds.
3. ​​Ignore the installation environment​​: The seaside project did not choose anti-salt spray coating, and the rust rate of lamp beads in three months is as high as 18%.

To give a real case: The P10 grille screen installed in a exhibition center last year did not consider ventilation and heat dissipation, and the death rate of high temperatures in summer sky soared to 5%, and it cost more than 200,000 yuan to be used for repairs alone!

​​2. Core parameters: These indicators are the real guys​​

​​Q: What parameters directly affect the user experience? ​ ​

1. ​​Structural strength​​：
   • Aluminum-magnesium-zinc alloy box has a flexural resistance of 3 times higher than ordinary aluminum
   • IP65 protective box used in sports venues can withstand heavy rain
2. ​​Optical properties​​：
   • Low brightness and high gray technology allows the screen to display 16 bits of fine gray scale at 800cd/m² brightness
   • Refresh rate ≥1920Hz, the vehicle can see dynamic information clearly when passing by 80 yards
3. ​​Energy-saving performance​​：

   project	Ordinary products	High-quality solutions
   Power consumption per square meter	650W	380W
   Five-year electricity bill difference	98,000 yuan	56,000 yuan

​​3. Scene adaptation: Buy the right one but not the expensive one​​

​​Q: How to choose configurations for different places? ​ ​

1. ​​Commercial complex​​
   • Transparent grille with a gate transparency of > 85%, can be used as an advertising screen without affecting the lighting
   • Case: A shopping mall embeds a grille screen in a glass curtain wall, and the decoration is turned into a display screen at night, and the passenger flow has increased by 23%.
2. ​​Stadium​​
   • Must have an anti-collision structure arc screen with an inclination angle of at least 25°
   • Tested data: The box with intelligent temperature control can accelerate the startup speed by 40% in -20℃ environment
3. ​​Transportation hub​​
   • It must be able to resist electromagnetic interference and support real-time switching of multilingual languages
   • A certain airport uses a P6 screen with light-sensitive adjustment, and the visual distance under strong light is increased to 80 meters.

​​4. Service guarantee: Don’t turn after-sales service into bottomless holes​​

​​Q: How to judge whether the manufacturer is reliable? ​ ​

• ​​Production strength verification​​：
  • Check if there is a level 10,000-level dust-free workshop, the mold accuracy must be controlled at ±0.1mm
  • Manufacturers with monthly production capacity less than 5,000 cubic meters, delivery in peak season can delay you for three months
• ​​Technical support system​​：
  • The 24-hour response technical team is not a decoration, it must be able to remotely diagnose faults
  • Modular design is really not a shame, it will be done in 15 minutes when changing the module on site.
• ​​Certification threshold​​：
  If you can’t get any basic certifications such as CCC and CE, please block them as soon as possible!

Just buy LED grille screens, just like finding a decoration team - you can't just look at how beautiful the model room is, you have to look at whether the hidden project is done well. Next time you go to inspect the suppliers and focus on their aging test workshop. The screen that can be continuously roasted in a 50℃ environment for 72 hours is absolutely not bad to use! Remember, good products + good service are really saving money. Those who are outrageously low in 80% cut corners in invisible places!
