Alas, many friends recently asked me: "I want to install a cool LED large screen at the entrance of the mall. Which splicing technology is better?" To be honest, this problem is like finding a partner - looking at a lot of glamorous people, it is difficult to find someone who really wants to live a down-to-earth life. Today we will talk about how to avoid those fancy routines and find truly reliable LED splicing services.

1. Look at the technical parameters like a physical examination report

Let me give you an example first: choosing a splicing screen is like a physical examination, and the data will not be lie. ​**If the refresh rate is lower than 1920Hz, don’t touch ​**, otherwise you will play a fast moving picture and make a real shadow for you, just like an old TV snowflake screen. Last time we installed interactive floor tiles for the mall, the customer insisted on saving the money. As a result, the parkour video was displayed on the opening day, and the customers said they were dizzy and wanted to vomit.

Let’s talk about brightness adjustment, indoor and outdoor are all two different things.​If the indoor screen of 800-1200cd/m² is installed outdoors, it will be like a mosaic when the sun is shining.​. Last year, I helped the gym install a front desk sign. A colleague used low-end products with cheap prices. Now I have to use sunshades in broad daylight. Are you embarrassed?

2. Service guarantee is more important than dating

Do you know what's the most annoying thing? Even after installing the screen, the person disappeared. The most outrageous case I have ever seen is that the advertising screen of a supermarket chain was installed for three months, and it suddenly turned black on a rainy day. I contacted the manufacturer and said that the technician had changed jobs. So now we recommend service providers to customers. The 24-hour technical response is the bottom line, just like buying insurance. You can do it without it but you can't do it without it.

Let me reveal another insider of the industry: the so-called "full-process service" of many manufacturers, but in fact they just let go after installation and debugging. What is truly reliable is to start from the design drawings. We did three times the curved screen solution we made for Singapore shopping malls. The customer boss also said at the time: "You are so serious, it's like building an airplane."

3. Product certification is not a decoration

To be honest, those manufacturers who cannot provide ISO9001 certification are as dangerous as those who go on the road without a driver's license. Last year, a supplier was selected for a rental screen in the exhibition center. But when he saw that the CE certification was fake, the aluminum, magnesium, zinc box was actually painted with iron, and it was directly deformed and scrapped during transportation.

The key is to give you three hard rules:

• ​IP65 protection level starts​, especially the stadium fence screen, you are not afraid of rain or wind
• ​​Transparent screen with a transmissivity of over 85%​You can only use it as a window, otherwise it would be like a matte film
• ​​The box splicing error must be less than 0.1mm​​, try this with a bank card

4. Actual cases are more realistic than advertising slogans

Let’s take the transparent window screen in Korea for example. The customer first started looking for a small workshop with cheap pictures, but the screen thickness exceeded the standard, and after installing it, the window turned into a safe. Later, I found a 3.5mm ultra-thin screen made by a professional team. Now I play videos of new bags. Passers-by can see the leather texture through the glass, and sales have increased by 30%.

There is also the stadium project in Japan that is more interesting. The original fence screen was played with a goal replay, and the pictures were torn when the players ran. After changing to professional-grade equipment, even the afterimage of fans waving the flag can be captured clearly. The venue operator praised everyone: "This money is worth spending!"

5. Teach you three tricks to prevent pits

Finally, let’s give some tips to newbies: 1. ​**Don’t believe in the "lowest price in the industry"***. The LED screen cost is very transparent, and excessively cheap will cause evil. 2. ​**​Watch the aging test on site. Only those who have no dead points in continuous roasters for 48 hours are qualified. 3. ​**The contract must clearly write the warranty scope***, especially the details of waterproofing and dustproofing.

A customer was very funny two days ago and asked me with a quote from five companies: "The price difference is as good as a vegetable market. What should I choose?" I took him directly to the factory to see the automated production line. It was better than anything else when I saw it. Now their shopping mall's 4K advertising screen has been running for half a year, and even a bad point has not appeared.

After all, looking for LED splicing services is like finding a doctor and an expert—​Look at qualifications, cases, and after-sales service​​, only by completing three things can you be at ease. Next time someone will yell "It's absolutely okay" to you, so I will throw this article to him, so I will definitely leave him speechless. Remember, good screens are not afraid of being too late, but they are afraid of losing money by being greedy for cheap things!
