Dear friends, have you been dazzled by various advertisements of "local factory direct sales" recently? Especially friends who want to find LED display manufacturers near Yanbian, I guess they are all thinking: Where should I find this thing? Don’t panic! Let's talk about something real today-​​Don’t just stare at the map and look for the factory building. Maybe you can’t even figure out where the factory gate is opened!​​

1. Is there really an LED display factory in Yanbian?

Let me tell you the truth first,There are not many ready-made display factories in Yanbian​. Last year, a restaurant owner insisted on finding a "manufacturer at home", but he went all over Yanbian Korean Autonomous Prefecture and finally found that the so-called "factory" was actually a small assembly workshop. What does this tell us?​​When finding a factory, you can’t just look at the geographical location!​​

Why do you say that? Look:

• The LED display industry chain is basically concentrated in the Pearl River Delta and the Yangtze River Delta (for example, there are more than 500 related companies in Shenzhen)
• The core components of the screen, such as lamp beads, driver ICs, and power supplies, are shipped from Guangdong.
• Even if there is a factory located in Yanbian, the raw materials have to be shipped from the south, and the cost will be higher.

2. Find three core indicators for manufacturers

Since it is difficult to find local factories, what should I look at?​​Remember these three hard levers are better than anything else:​

​​1. Check the household registration by looking at the production qualifications​​
ISO9001 is the basic threshold, and CE and 3C certification must not be missing. A while ago, a customer looked for a small factory with cheap pictures, but the screen flashed after half a year. He sent it for testing and found that there was no RoHS environmental certification.

​2. It is better to see the implementation case than to listen to brag​
All serious manufacturers dare to show off real-life photography projects. International projects such as the transparent window screen in Myeongdong, Seoul and the fence screen in the Tokyo Stadium are not something that any factory can take.

​3. See if technical support can be available on call​
The key point is here! Some manufacturers disappear after signing a contract. The reliable ones range from design management to after-sales maintenance. I heard that some manufacturers set up 24-hour technical service stations in Japan and South Korea, and they can arrive for two hours if there is any problem in the middle of the night.

3. Teach you three tricks to identify manufacturers

Now the question is, how to judge whether the other party is a real factory?​​These three moves are definitely correct:​

​​The first trick: Video factory inspection​
Don't believe in the Internet pictures! Let the sales directly open a live video production line. Small workshops are reluctant to invest tens of millions of equipment such as automated patch machines and aging test rooms.

​​The second trick: Check the customs declaration form​
For manufacturers exported to Japan, South Korea and Southeast Asia, customs data cannot be faked. Last year, a Shenzhen company only had 87% of exports, which is not a pity.

​​The third trick: try to ask for samples​
The one who dares to send samples is the real boss. Pay attention to whether the arrangement of the lamp beads is "horizontal and vertical", and whether the splicing seams can be stuffed into the bank card (preferably ≤0.5mm)

4. Those doorways for transportation and installation

Even if you find a reliable manufacturer, there is still a hurdle—​How to safely transport screens from far away?​​ There is a lot of knowledge here:

• ​​Logistics should choose a dedicated line cold chain vehicle​(The temperature difference between ordinary trucks will cause module deformation)
• ​​The installation team must be certified to work​ (The most powerful person I have ever seen used a decoration team to decorate the stadium large screen, but the signal cable was connected to the reverse and the control card was burned)
• ​​Pre-test voltage stability​(Some places in Yanbian have large voltage fluctuations, so a voltage regulator must be installed)

To give a real case: Last year, an advertising screen purchased by a shopping mall in Yanji from other places was not made of shock-proof packaging, and all 32 modules were shattered when they arrived, with a loss of less than 200,000!

5. The thoughts of old purchasing

After working in purchasing for more than ten years, I finally gave some advice to novices:

1. ​Don't be fooled by "direct sales from manufacturers"​
   Many so-called direct sales are actually second-hand dealers. Teach you a ruthless trick: let the other party issue a raw material purchase invoice for the past three months

2. ​​The contract must state technical indicators​
   For example, refresh rate ≥1920Hz and automatic brightness adjustment range, so you won’t be afraid of being ripped off by white paper and black text.

3. ​​Reserve 10% warranty​
   Wait until the screen is stable and runs for three months before paying the final payment. I have seen too many acceptances and it will start to lose the link after using it for two months.

After all, finding an LED display manufacturer is like finding a partner—​​The key is to rely on internal strength, you cannot just look close to it.​. Next time someone will tell you "There is a factory in Yanbian", so you can throw this article to him. Remember, good screens can speak by themselves, and manufacturers that can stand the inspection of magnifying glass are truly worthy of entrusting partners!
