LED advertising display battery position and usage and maintenance strategy

2025-08-08 159

Alas, friends who are just getting involved in LED screens, have you stared at the moving large screen outside the mall and stared at it? I thought about it secretly——​ ​Such a big guy, where is the "heart" battery that powers it?​​? Let’s talk about this today, so you can hear it clearly!

LED广告显示屏电瓶位置与使用维护全攻略

1. The battery is not what you think is "power bank""

Let’s correct a misunderstanding first. Many novices will imagine the battery of LED screens as the battery of electric vehicles. ​ ​In fact, the professional name is the switch power module​​, looks like a metal box, and specializes in converting 220V AC into DC power that can be used on the display screen.
Let’s give a practical example. Just like our NewScreen outdoor advertising screen, it uses military-grade lightning protection power supply. Last month, three large screens were installed on a commercial street in a tropical country in Southeast Asia. After several thunderstorms, they were still lit up.——​ ​The key is that the power bank has triple isolation protection​​。


2. The battery position depends on the "three major elements"

Finding a battery position is like playing hide-and-seek, mainly looking at these three aspects:

  1. ​Installation method​​: The column type is usually in the base, and the wall mounted is usually at the top maintenance port.
  2. ​Waterproofing requirements​​: The power chamber of the outdoor screen will be covered with "waterproof clothing". For example, the screen we made for the beach project, the power position is 20cm higher than the conventional model.
  3. ​Heat dissipation requirements​​: Last year, the arc screen made for a shopping mall in Seoul was specially distributed in four cooling zones.

3. Teach you step by step to position the battery

  1. ​Look at the structural drawings​​: Regular manufacturers will mark the inspection port position at the border, just like every screen we ships with QR code electronic instructions
  2. ​Touch temperature changes​​: After half an hour of power-on, touch the back of the screen with the back of your hand——​​Areas with obvious fever​​Eighty percent of the power supply area
  3. ​Listen to the sound to recognize​​: The power supply with good quality is basically silent. If you hear the "buzzing" sound, hurry up and contact a 24-hour technical team like ours

4. Position design directly affects life

Last year, there was a reverse textbook. The LED floor tiles screen in a certain amusement park has suffered frequent failures in just half a year. Later, when I opened it, I saw that the power supply was actually stuck to the cooling air outlet, and the condensate was dripping on the circuit board! ​ ​Our products are more particular about this​​:

  • Outdoor screen power bin comes with silicone moisture-proof pads
  • Quick release power tray for rental screens
  • Transparent screen made into independent split power supply
    Just like the fenced screen used in a stadium in Tokyo, the power module is specially placed under the auditorium to repair the well, and there has been no power supply failure in five years.

I have to tell you, the battery position seems to be a trivial matter, but it actually hides great knowledge. ​ ​A good power supply layout must not only consider heat dissipation and waterproofing, but also facilitate maintenance.​​Just like the 8K large screen we made for a landmark in Shenzhen, the power bank alone has iterated three versions. Next time you see the shiny LED advertising screen, you might as well guess where its "heart" is hidden - maybe it is designed according to the tricks we are talking about today!
