Are you also curious about where those magical floors that light up and change patterns when you step on them are made? Let alone ordinary people, I went to a concert last year and when I saw fireworks exploding on the stage floor with special effects, my first reaction was to take out my mobile phone and check the address of the manufacturer - and guess what? The home of these high-tech gadgets is actually right under our noses!

The secret base in the heart of manufacturing

When it comes to the source of LED floor tile screens, eight out of ten companies are gathered here.​ ​Pearl River Delta​ ​. Taking 70% of the country's LED production capacity as an example, there are hundreds of related companies in Bao'an District of Shenzhen alone. There is an unwritten rule here: drive around three kilometers and you can find a complete set of suppliers from chips to cabinets.

There is a company that has been deeply involved in the industry for more than ten years, and its headquarters is directly located in Shenzhen.​ ​Shiyan Science and Technology Park​ ​. I visited their production base last year. It has two floors of automated assembly lines, and the robot arm can grab the box faster than my hands can play games. What shocked me the most was the quality inspection process - each floor tile screen has to undergo 72 hours of non-stop testing.​ ​Heavy rain mode + stampede test​ ​, no wonder he was not spoiled by the stars dancing all night long at the concert.

Why do everyone like to squeeze in here?

At first I was wondering, why don’t such high-tech things go to Beijing and Shanghai? Later, after drinking with a master in the industry, I found out the truth:

1. ​​The supply chain is more convenient than takeout​ ​: I need a driver chip in the morning. Just make a phone call and it will be delivered to the factory gate in the afternoon.
2. ​​Skilled workers are everywhere​ ​: In Shenzhen, there are more masters who can program LED control systems than taxi drivers.
3. ​​Going to sea is like visiting a house​ ​: Shipping goods from Yantian Port to Southeast Asia is faster than taking the high-speed rail from Shenzhen back to my hometown.

Speaking of which, a real story comes to mind: Last year, a top Korean boy band went on tour, and the stage director made a temporary request to expedite a 300-square-meter floor tile screen. As a result, from order receipt to air delivery in Shenzhen, it only took​ ​96 hours​ ​, I heard that I also helped them debug the support color gradient program.

Black technology hidden in the factory

Do you think floor tile screens are just glowing tiles? That would be to underestimate these manufacturers. Once I saw a new product being tested in the workshop, and the technical parameters made me stare:

• ​​The refresh rate soars to 1920Hz​ ​: In layman’s terms, the screen switching is 60 times faster than the blink of an eye, and there will be no smear at all.
• ​​Brightness intelligent adjustment system​ ​: It can reach 7,500 nits outdoors in bright sunlight during the day, and automatically drops to a non-dazzling level at night.
• ​​Exclusive earthquake-resistant structure​ ​: The box body is made of aviation-grade aluminum-magnesium alloy, and it will not be deformed when a truck drives it over it.

The most amazing thing is their home​ ​Transparent screen technology​ ​, I have personally seen a sample with a light transmittance of 86%. It can be installed in a shopping mall window to display advertisements without blocking the view. No wonder even luxury stores in Ginza, Tokyo are rushing to get it.

How does global order work?

You may not imagine that these companies hidden in industrial parks are actually engaged in "international events" every day. For example, during the World Cup in Qatar last year, there was a circular floor tile screen project for the venue. From design to installation, only​ ​45 days​ ​Construction period. The manufacturer directly dispatched a technical team of 20 people to station at the site, debugging during the day and training local workers at night. In the end, the countdown was completed to complete the delivery.

Now their container trucks are equipped with GPS positioning systems. I have seen the large screen in the control room flashing the transportation logos of more than 30 countries at the same time. Once while chatting with the sales director, an alert suddenly popped up on his mobile phone - it turned out that the freighter bound for Singapore encountered a typhoon detour, and the system automatically activated the emergency plan. The response speed was faster than my router at home disconnecting and reconnecting.

Editor's opinion

Seriously, the next time you see the discolored sidewalks in a shopping mall or the exploding special effects on the ground at a concert, don’t just take photos and post them on Moments. Think about these technology companies hidden in industrial zones. They have taken Chinese manufacturing to a new level - using Shenzhen speed for research and development, using German standards for quality control, and finally letting the whole world pay for our black technology. Isn’t this more exciting than chasing stars?
