Where are the advertising LED display factories hidden?

Do you often see those cool LED large screens in shopping malls, stadiums and even on the roadside? A question must have flashed in my mind - these things that are dozens of meters wide at any timeAdvertising LED display, which mysterious factory was built from? Today, let’s take a look at the “screen building base” of this industry. After reading it, you will be clearer than those in the industry!

1. First draw the key points: the three major gathering places for China's LED factories

1. Pearl River Delta Golden Belt
To talk about the big screen makers,ShenzhenAbsolutely firmly sits in the top spot. Not only is there the world's most complete LED industry chain, but even the screws can be found within a radius of five kilometers. For example, a large factory with a monthly output of tens of thousands of square meters only takes 15 days from receiving orders to shipments, relying on a full set of suppliers within a half hour's drive.

2. Yangtze River Delta Innovation Circle
Shanghai and Suzhou are playing high-end routes, focusing onSmall spacingandTransparent screen. Last year, there was an Internet celebrity milk tea shop's front desk interactive screen, which was only as thin as a mobile phone, and it was the masterpiece of the factory here.

3. Chengdu-Chongqing New Forces
Don’t look in the inland area, Chongqing and Chengdu are now the "invisible champion" of outdoor screens. Why? The labor cost is 30% lower than that of the coastal areas, but the technical level is not bad at all. Many circular screens in stadiums are built here and shipped directly.

2. The secret to choosing a factory: teach you three tricks to see through the strength of the factory

The first trick: Looking at the workshop is more important than looking at the samples
A real big company dares to let you visit the production line! Focus on these three points:

Patch workshopIs there any fully automatic device (direct pass for manual patches)
Aging test areaIs it true that the screen is 24 hours a day (there is no problem when testing for 72 hours)
Packaging assembly lineIs there any anti-collision design (those who have broken the screen know how important this is)

The second trick: Don’t be fooled by the parameters
The easiest pit that Xiaobai stepped on is to believe the nonsense of "P". Remember this formula:
Effective viewing distance (meters) = pixel spacing (mm) × 2
For example, if you hang a 3-meter-high screen in the mall, selecting P3-P4 is enough. If you have to go to P1.5, it is purely a burning money!

The third trick: Don’t just look at ISO for certification
Truly reliable factories have these "amulets":

CE certification (Enough to export to the EU)
CCC certification(Domestic sales threshold)
ROHS Test Report(Environmental protection hard indicators)
Lightning protection certification(Outdoor screensaver symbol)

3. Reveal the industry: Why do big factories like to gather in Shenzhen?

Last year, a data shocked me - 60% of the country's LED displays are from Shenzhen! Why are you squeezing here? To put it bluntly, there are only three words:Fast, full, and conservative！

Quick: You need to modify the design drawings in the morning and you can get new samples in the afternoon. The mold factory, chip factory and driver factory are all on the next street, which is more convenient than ordering takeaway.

All: From the most ordinary door head screen to the 8K theater-level giant screen, there is no job that the Shenzhen factory cannot take on. I heard that a factory has created a three-in-one "dream combination screen" of arc + transparent + floor tiles for Dubai.

Save: The logistics cost is so low that you can't imagine. When transporting a container to Yantian Port, the freight rate is half that of other cities, which is why 87% of exported products go to Shenzhen.

4. Guide to avoid pits: Don’t choose these factories!

1. Guerrillas fighting price wars
What is the quote 30% lower than the market price? Be careful to use second-hand lamp beads! This kind of screen started to be blinded, and it started to "grow pockmarked" (dead light) after half a year.

2. Assembly plant without R&D department
The detection method is super simple - ask them about the latest patent number. Real-technical flow factories can issue five or six patents, and those who are hesitant are probably assembled by buying public modules.

3. The "cloud factory" that relies on express delivery after-sales service
Focus on after-sales terms! A reliable factory dares to write "2-hour response, 48-hour attendance", but will only say "I send it back to repair it in person". If the screen breaks, just wait and cry.

5. Future trend: What kind of black technology are the factories busy with?

Recently, I visited several major factories and found that their laboratory is fiddling with these things:

Self-repair screen: It can automatically repair minor scratches like skin
Zero power consumption standby: The shutdown state can maintain the basic display by relying on ambient light.
Smell display: The fragrance can really come out when displaying perfume advertisements
The most amazing thing is from a certain factory5G smart screen, the ad can be automatically switched according to the age and gender of the passing crowd, and it is said that the click-through rate has increased by 40%!

Editor's opinion

After working on the display screen for so many years, my biggest feeling is-The good screen really depends on the parents' home! Just like when choosing a partner, you can’t just look at your appearance, you have to find out your family’s background. Next time you have to order the screen, don’t rush to compare prices. First, ask if there is a fully automatic production line in the factory workshop, if the technical team has more than ten years of experience, and if the successful cases are real photos. Remember, those who dare to bring customers to the workshop are real big shots. Those who only show you PPTs should be blocked as soon as possible!
