Hey friends, the cool advertising screens you see every day when you pass by shopping malls, the background walls that blind your eyes at concerts, and even the fence screens in stadiums that broadcast live games - where did these LED displays come from? Are they all high-end goods imported from abroad? Today we will explain this matter in detail, and I’m sure you will slap your thigh after listening to it: “So that’s what happened! "

1. What does the "manufacturing map" of global LED screens look like?

You may not believe it, but now in every 10 LED screens in the world,​ ​At least 7 pieces are labeled "MADE IN CHINA"​ ​. Especially in the Pearl River Delta region, a complete industrial chain from chip packaging to complete machine assembly is gathered here. For example, at an automated factory in a science and technology park in Shenzhen, the production line alone is as big as a football field. The monthly production capacity easily exceeds 10,000 square meters, and the fastest time from order placement to shipment is 72 hours.

​​The three major industries will teach you:​​

1. ​​Pearl River Delta​ ​: Focusing on high-end customized screens, black technologies such as transparent screens with 86% light transmittance
2. ​​Yangtze River Delta​ ​: Specializing in commercial advertising screens, the market share of outdoor large screens exceeds 60%
3. ​​Chengdu and Chongqing regions​ ​: Focus on the development of rental screens, and the technology of quick disassembly and assembly of boxes is unparalleled in the world.

Here’s a little trivia: LED screens with the same parameters can vary in price by 20% from different places of origin! For example, the IP65 waterproof screens used in sports venues are 15% more expensive than those produced in the Mainland, but their lifespan is generally 2-3 years longer.

2. Where is the "heart" of a good screen?

To judge the origin of the LED screen, the key is to look at these three parts:

There was a classic case last year: a music festival used two sets of rental screens at the same time. As a result, half of the screens went black during a heavy rainstorm. Later, when I dismantled the machine, I found that the bad power modules were all cheap ones, and the protection level could not reach the nominal IP65 at all.

3. Why is it said that "origin ≠ quality"?

I need to pour some cold water here.——​ ​Don’t close your eyes and buy when you see “Made in Shenzhen”​ ​! Products from the Pearl River Delta may differ greatly in quality. Teach you three ways to distinguish authenticity:

1. Touch the heat dissipation holes: If the temperature exceeds 50°C under working conditions, 80% of them use inferior power supplies.
2. Look at the certification marks: Look for hard-core certifications such as CE and CCC, especially for models exported to Japan and South Korea.
3. Check production traceability: regular major manufacturers can provide chip batch traceability reports

Take the transparent screen as an example. It is a product with a real light transmittance of 86%. If you move your hand behind the screen, you can clearly see the outline of your five fingers. If it is blurry like frosted glass, go to the seller to discuss it!

4. The soul torture that novices are most concerned about

​​Q: Can I buy cheap screens online? ​ ​
A: It depends on the situation! If it is a standard-size indoor poster screen, the price difference is mainly in the brightness uniformity (top-level screens can achieve more than 95%). But don’t be greedy for cheap when it comes to large outdoor screens. Last year, a billboard in a third-tier city collapsed because of the use of second-hand refurbished modules.

​​Q: Are imported screens really better than domestic ones? ​ ​
A: This was true ten years ago, but now the parameters of domestic high-end screens are more radical. For example, the special screen for studios that supports 1920Hz refresh rate, the price of domestic products is only two-thirds of imported products, and it also comes with a five-year warranty.

​​Q: How long does it take to customize the screen? ​ ​
A: It depends on the strength of the factory. A Shenzhen company received an order for a curved screen for the Tokyo Stadium. It only took 28 days from design to installation. The key is that they have an automated workshop of 10,000 square meters, and even the cabinets are formed in one go by CNC machines.

Editor's opinion

Let me tell you, choosing an LED screen now is like buying a mobile phone.——​ ​Don’t just look at the brand, take it apart and look at the configuration.​ ​. Why do those large manufacturers with a monthly production capacity of over 10,000 square meters dare to promise 24-hour technical response? There are tens of thousands of universal modules in their warehouse! Remember this the next time you purchase: asking the manufacturer to show you a video of the workshop is much more effective than reading a brochure. The future LED market will definitely focus on technical reserves and service speed. Do you think this is the truth?
