​​Alas, have you seen LED screens that can play advertisements by themselves without even having to computers? ​ ​
I believe you have seen large screens that can play advertisements in shopping malls and subway stations, but you may not know these​ ​A display that can work independently​​There is a professional name called LED asynchronous screen. To put it bluntly, it is a display screen with its own "brain". It does not require real-time signal cables to store the content into the screen to play it yourself. This kind of technology is everywhere on the street now, but do you know where these screens pop up?

​​1. What is an LED asynchronous screen? ​ ​
Let’s first clarify the concept. The biggest difference between an asynchronous screen and an ordinary LED screen is like a mobile phone and a landline——​ ​One has a built-in processor, and the other must be wired to use it​​. To give a specific example, the screen that circulates discount information every day at the door of your convenience store downstairs is a 90% asynchronous screen. It contains control cards and memory chips. The clerk can just use a USB flash drive to update the content, and there is no need to use a computer to watch it.

The most awesome thing about this kind of screen is that​​Super adaptable​​: From the Northeast Ice and Snow World at minus 20℃ to the Hainan scenic spot with high temperature of 40℃, it can be used as long as it is installed in a waterproof box. Just like the fence screen made by our company for Tokyo Stadium in Japan, the IP65 protection level can withstand heavy rain and hail. It has not failed after three years of use.

​​2. Where are these magical screens hidden? ​ ​
If you think that asynchronous screens can only display advertisements, you will underestimate it too much. I have sorted out several of the most common application scenarios:

• ​​Shopping mall windows​​: The popular transparent LED screen now has an 86% transmittance that does not affect lighting, and will automatically broadcast promotion information at night
• ​​Bus stop​​: Screen with light sensing, automatically increase brightness at dawn, and automatically reduce power consumption during dark
• ​​Warehouse board​​: Can directly access the warehouse management system and display inventory data in real time
• ​​Temporary Activities​​: Use quick disassembly and assemble the box, and you can set up a concert-level background wall in two hours

There is a particularly interesting case. A supermarket in South Korea used our floor tiles to lay the fresh food area. When customers stepped on the hairtail pattern area, the cooking tutorial video immediately popped up on the screen. This​ ​Interactive gameplay​​Now it is getting more and more popular. Last year, the creative interactive orders alone accounted for 35% of our total sales.

​​3. What are the tricks to choose an asynchronous screen? ​ ​
The easiest pit for beginners to take is to only look at the price. Let me tell you the tips for choosing only a few experts:

1. ​​Control card depends on memory​​: You must be able to save at least 500 pictures + 10 hours of videos, don't buy cheap goods that can only save dozens of pictures
2. ​​The brightness will change by itself​​: Our indoor screen comes with 800-1200 nits of intelligent dimming, and it can be seen clearly at midday sunlight.
3. ​​The heat dissipation design is the lifeblood​​: Touch the back of the prototype, and the hot pass is the real thing - the aluminum-magnesium alloy box is the real product

A customer used to buy a miscellaneous screen with cheap pictures, but after using it in the humid and hot weather in Guangzhou, it took three months to spend the screen. Later, we changed our rental screen.​ ​Quick disassembly and assemble structure​​With dual fans, it is fine to use it with high intensity for 48 hours. So there is a reason to be expensive, and key components really cannot be saved.

​​4. The factory location is hidden in industry secrets​​
You may not have imagined that 80% of the world's LED asynchronous screens are produced in China, and​ ​Shenzhen is the core of the core​​. Why so concentrated? Three reasons are straightforward:

• ​​You can buy accessories when you go downstairs​​: Find all parts within a radius of 20 kilometers from chip to box
• ​​Technical iteration is faster than reading books​​: Like the 1920Hz refresh rate technology we developed, it only took 8 months from laboratory to mass production.
• ​​Save half of logistics costs​​: The port and airport are all at your doorstep, and shipping to Southeast Asia is faster than free shipping in Jiangsu, Zhejiang and Shanghai

Our factory is located in Shiyan, Shenzhen, in a 100,000-square-meter automation workshop. It uses robotic arms to operate from patches to assembly. Last month, I just customized a curved advertising screen for Singapore, and it only took 17 days from ordering to installing it - this speed is not something else in other cities.

​​Finally, say something heart-wrenching​​
After ten years of working in this industry, I have seen too many people blindly pursue new technologies. actually​ ​Stability and reliability are the lifeblood of asynchronous screens​​, like our products exported to Japan, 87% of our customers are repeat customers. Next time you choose a screen, first ask the manufacturer if you dare to sign a three-year warranty agreement, which is much more powerful than listening to sales bragging.

Now, do you know where these screens that can "think" for yourself come from? From the smart factory in Shenzhen to the convenience store downstairs of your home, it is not only technology, but also the wisdom of a complete supply chain. Next time I pass by the shopping mall window, maybe take a look at it - maybe that's what we did!
