Hey, many bosses have asked me recently: "Want to install a stunning LED advertising screen in the city center, but don't know where to start?" "This thing is just like buying a house. It looks similar, but the doorways inside are quite deep! Don't panic, today we will chat about this matter, and I'm sure you will feel enlightened after listening to it.

​​1. First understand these hard indicators​​
Buying an LED advertising screen is not like going to the market, you have to look for a few first​ ​Key parameters​​：
• ​​Bright enough​ ​: If you can't see clearly under the sun during the day, then the money will be wasted. The brightness of outdoor screens must be at least 4000cd/m². Those that can automatically adjust the brightness are even smarter. The brightness can soar to 7500 in the middle of the day, and automatically lower it on cloudy days to save power.
• ​​Waterproofing must be excellent​ ​: IP65 protection level is the bottom line, and it is still as stable as an old dog in heavy rain. Here’s a little bit of trivia – a good screen can fit an A4 paper into the seams without any water seeping in.
• ​​Don’t be fooled by pixel spacing​ ​: The smaller the numbers P6 and P8 are, the clearer they are, but the prices are also rising. Use P6 for shopping mall exterior walls and P10 for highway intersections. Don’t use it the other way around.

Let’s take a real case: Last year, a chain restaurant brand bought a screen that was not bright enough. As a result, customers could not see the promotional information clearly during the day. Customer flow dropped by 15% in three months, which was a huge loss!

​​2. How to choose purchasing channels​​
Now comes the important point, who should I buy from? There are three situations:
​​Situation 1: Urgent need​ ​ →Find a local supplier with a warehouse (logistics saves 3-5 days)
​​Situation 2: Need to customize​ ​ →Directly contact manufacturers with R&D teams (can save 15%-20% of the middleman price difference)
​​Situation 3: Overseas projects​ ​ →Look for CE/FCC certification (a necessary stepping stone for customs clearance)

Here’s an insider’s secret:​ ​Monthly production capacity exceeds 10,000 square meters​ ​The quality stability of these manufacturers is two levels higher than that of small workshops. Why? Even the screws in their production line are tightened by robots, and the error is no more than the thickness of a hair!

​​3. Guide to avoid pitfalls (heart-breaking version)​​
When buying a screen, you are most afraid of encountering these pitfalls:
• ​​Quotation plays word games​ ​(Installation fees and software fees are calculated separately? )
• ​​Deceiving people with renderings​ ​(Remember to watch the video factory inspection to see the actual product! )
• ​​The after-sales phone line is always busy​ ​(The worst thing is to lose the chain at the critical moment)

Last year, a friend fell into this trap. The screen he bought went black after three months of installation. As a result, the manufacturer moved the warehouse and couldn't find anyone. So,​ ​24-hour technical response​ ​This must be written into the contract, only if it is written in black and white!

​​4. Hidden skills that only experts know​​
Teach you three tips to save worry and money:

1. You can get a 5%-8% discount on year-end purchases (you know how manufacturers compete for performance)
2. Comes with a three-year extended warranty (save 10,000 less than buying it alone)
3. You can negotiate installments for bulk purchases (cash flow pressure is halved)

Nowadays, all high-end screens have​ ​Remote diagnostic function​ ​, if there is any minor problem, engineers can fix it via video guidance, especially for overseas projects, you no longer have to wait for cross-border air tickets.

​​Editor's opinion​​
After working for so many years, I feel that buying an LED advertising screen is like looking for a partner - appearance depends on parameters, but living a life depends more on "temper and temperament". Next time I go to inspect suppliers, focus on their​ ​Aging test workshop​ ​and​ ​Spare parts warehouse​ ​, these are the two places where the real skills are hidden. By the way, remember to let the technician demonstrate it in person​ ​Heavy rain simulation test​ ​, whether it is a mule or a horse, you will know after taking it out for a walk!
