Are you also worried about buying an LED display but don’t know where to start? Just like a novice who wants to buy a mobile phone, he is immediately confused when faced with the full screen parameters. What’s even more troublesome is that for the same P3 pitch display, some people quoted 8,000 while others asked for 30,000. The water here is deep enough to support whales. Today we are going to talk about something practical and teach you how to avoid the "tuition fees" we paid in those years.

​​The first pitfall: How to choose offline physical stores VS online platforms​​
Last year, a restaurant owner bought an indoor screen from the building materials market. It looked very cheap, but after three months, color patches appeared. After taking it apart, I found that the power module was actually second-hand! Here's a tip - when buying a screen offline, you must read the manufacturer's "Production Qualification Certificate" and "Shipping Inspection Report," just like buying a car requires reading the brochure. As for the online platform, don't look at the hype on the details page, focus on the "Ask Everyone" section. If you see comments like "The installation took half a month" or "The after-sales phone call cannot be reached", quickly cross it out.

​​The second trick: Understand the parameters so you don’t suffer.​​
Let's take a real case: A shopping mall bought an outdoor screen, and the parameters read "maximum brightness 4500cd/㎡", but it turned out that it was impossible to see clearly during the day. Why? Because the seller is playing a word game - this brightness can only be maintained for 10 minutes, and it will automatically reduce the brightness to 2500 after long-term use. Remember these key indicators:

• ​​continuous brightness​ ​: Outdoors must be ≥4000cd/㎡ (like the projects we do for Southeast Asia, they are all stable above 5000)
• ​​refresh rate​ ​: At least 1920Hz is required, otherwise the screen will be full of ripples when taken with a mobile phone.
• ​​Protection level​ ​: IP65 is the bottom line for outdoor screens. Splashing mineral water on it should look like water droplets rolling on a lotus leaf.

​​The third level: the sharp eyes during acceptance​​
Don’t rush to sign when you receive the goods. I’ll teach you three unique tricks for inspecting goods:

1. Hold the phone camera close to the screen and set it to slow motion mode. You won’t be able to see the scanning lines on a good screen.
2. Play a pure red picture, use a magnifying glass to see if the color of the lamp beads is consistent. If there is yellowing, it is an inferior lamp.
3. Touch the temperature of the screen frame. If the temperature exceeds 50℃ after 2 hours of operation, return it immediately.

Someone asked: Would it be more cost-effective to customize the screen? This needs to be said twice. For example, the curved fence screen we made for the Tokyo Stadium is indeed 15% cheaper than the standard product, but the minimum order quantity is 200 square meters. If it is a small shop that wants to install a front screen, it is more reliable to choose the standard size. After all, the mold opening fee is enough to buy half a screen.

Finally, let me talk about the hidden rules of the industry: Never believe the nonsense of "lifetime warranty". All serious manufacturers offer a three-year warranty and provide paid maintenance in the fifth year. Those who dare to claim a lifetime warranty will probably switch to selling seafood after only three years. Remember, a good screen is like finding a partner - the key is the after-sales response speed. The one that can come to your door for repair within 24 hours is really reliable.

The next time you pass by a shopping mall, you might as well keep an eye out for those display screens that can withstand the elements. You will find that a truly good product never needs to be plastered with slogans of "low price". Its stability and image quality speak for themselves. When it comes to buying LED screens, in the final analysis, don’t be greedy for small gains. Find a supplier who can clearly explain the technical parameters and use case photos without beautification. That’s better than anything else.
