Friend, are you looking for LED display manufacturers on the streets of Huoqiu? I have read all the recommendations of a certain voice in the same city and found that there are quotations ranging from 300 yuan/㎡ to 3,000 yuan/㎡? Don't worry! Today we broke it apart and said - installing LED screens in a small place in Huoqiu, who should we find to avoid cheating?

1. Is there really an LED screen manufacturer in Huoqiu?

You may not believe it if you say it. Last year, I traveled around the Chengnan Building Materials Market, and eight of the ten signature stores said they could make LED screens. After careful investigation, I found that:

• ​​Real local production​ ​There are very few manufacturers
• Ninety percent of businesses​ ​Second-Dao dealer​ ​(Transferred from Wuhu, Hefei)
• The remaining 1% may not even see the SMT patch camera.

To give a real case: A supermarket in Chengdong installed a P5 indoor screen last year, and the screen was black three months later. After taking apart, I saw that the power cord was actually a network cable! The merchant had already run away, and in the end the supermarket owner could only spend double the money to find another manufacturer to rework.

2. Experts teach you three steps to lock in reliable service providers

​​Step 1: Check the hardware configuration list​​

• The lamp bead must be used​ ​Gold wire copper bracket​ ​(Life life≥100,000 hours)
• The power module must be​ ​Industrial-grade waterproof model​ ​(Certify IP65 certification)
• Control system with​ ​Intelligent temperature control function​ ​(It can automatically reduce frequency in summer)

​​Step 2: Ask for installation after-sales details​​

• Do you dare to sign​ ​Three-year contract agreement​​？
• Can I go to the door for maintenance within 2 hours on heavy rain?
• Is there any charge for control software updates?

​​Step 3: Check the actual shooting of the landing case​​
Don't believe in the promotional pictures! Directly to the customer site to see the effect:

• Watch at 12 noon​ ​Display effect under direct sunlight​​
• Touch the screen border with your hands​ ​Feel the heat dissipation situation​​
• Let the merchant demonstrate on the spot​ ​Emergency power outage recovery function​​

3. Comparison table of local vs foreign manufacturers

Let’s focus on the Pearl River Delta manufacturers - although they are far away, they can make a living! Last week I met a boss who was a wedding screen and ordered it directly from Guangdong.​ ​Flexible soft screen​ ​The wedding scene was heart-shaped, and the bride was so moved that she burst into tears!

4. I have stepped on these tricks for fellow villagers Huoqiu

​​Pit 1: Low-priced packages disappear​​
There is a merchant in Chengbei Building Materials Market quotation of 680 yuan/㎡, and the contract actually contains the overbearing terms of "not including control systems"! I will tell you that you will have to spend 20,000 yuan to buy software after installing the screen. Is this operation slutty?

​​Pit 2: One-stop parameter fraud​​
A businessman boasted about "P3 high-definition screen", but actually pretended to be blackened with the P4 screen! Teach you a ruthless trick: take a hand​ ​Electronic vernier caliper​ ​When measuring the spacing between lamp beads on site, the error exceeds 0.1mm, the alarm will be called directly!

​​Trap 3: Copycat after-sales service acts like a scoundrel​​
The most outrageous thing I have ever encountered: the control software given by the merchant was actually a pirated version bought by Taobao! After the system crashed, even the manufacturer could not be contacted, so in the end, he spent 30,000 yuan to ask Shenzhen engineers to rewrite the program.

The editor's experience in 10 years of tricks

When installing an LED screen in Huoqiu, my bloody experience is just three sentences:

1. ​​Don't be greedy for cheap selection of guerrillas​ ​(The money saved is not enough to repair the screen once)
2. ​​Death-fighting test report​ ​(Certify the three-piece set of CE+CCC+ISO9001)
3. ​​Must be inspected on the spot​ ​(Focus on whether there is dust removal equipment in the SMT workshop)

I've discovered a new trend recently:​ ​Remote operation and maintenance system​ ​It's becoming popular! The outdoor screen installed by a friend last month, the manufacturer can monitor the screen temperature and humidity in real time in Guangzhou, and automatically push warnings when it finds abnormalities. If this technology was popularized earlier, the owner of Chengdong Supermarket would not have lost half a year of profit...
