Have you ever thought that the same kind of black technology is hidden behind the commercial streets you pass by, the gymnasiums you watch concerts, and even the information cards in the hospital every day? Yes, I'm talking about LED displays. These colorful screens are like the city's "electronic skin", quietly changing our lives. Today we will break it apart and talk about where these screens are shining and hot, and how to choose to avoid placing a pit.

​​1. Commercial Advertising: City Vision Bomber​​
When it comes to the most conspicuous existence of LED screens, there must be large outdoor advertising screens. For example, the P4 curved advertising screen installed by our company in Singapore is hung on the exterior wall of a 30-story building, and carousels of advertisements during day and night. What is better than traditional spray-painted posters? To put it bluntly, just three points:

• ​​Brightness is harsh enough​ ​: The brightness of the outdoor screen is 4000-7500cd/m², and it can still be seen clearly in the sun at noon
• ​​Resistant to fabric​ ​: IP65 protection level, no black screen when it is rained on typhoons for three hours
• ​​Flexible content​ ​: Selling cars today and promoting milk tea tomorrow, you can change advertisements by clicking on the mouse in the background

There is a way here - when choosing an outdoor screen, don't just look at the price. Last year, a shopping mall bought low-end goods with a bargain, but the color blocks fell off in less than half a year, and the repair cost was three times more than the money I saved at the beginning. Remember, the advertising screen must be selected with intelligent brightness adjustment, which is not dazzling during the day and does not consume electricity at night.

​​2. Stage performance: the creator of dream space​​
Now that the concert is held, I feel embarrassed to say that I am a top star without a few LED floor tiles. Our dance floor tiles screen is at a Korean music festival. The screen of singers’ three-hour dancer is still moving, relying on these hard-core configurations:

• ​​Refresh rate ≥1920Hz​ ​: The camera can't see the scanning line even if it is close to the face
• ​​Quick disassembly design​ ​: The tour team can set up a 500㎡ stage background in 2 hours
• ​​Low bright high gray technology​ ​: Black is as pure as a black hole during dark scene performance

There is a pit here: Don’t choose welding structures for rental screens. Once, I saved a music festival in Southeast Asia and found that their previous welding screen was disassembled and assembled by 30%, and our aluminum magnesium zinc box was disassembled and assembled by 20 times without deformation.

​​3. Sports events: Hot blood boiling catalyst​​
The fenced screen on the side of the football field is now standard, but there are many things to pay attention to. Why can the fenced screen used in a stadium in Tokyo withstand the crazy beating of fans? The key lies in these three designs:

• ​​Viewing angle 178°​ ​: Audiences at the top of the mountain can also see the score clearly
• ​​Anti-glare coating​ ​: The competition at noon is not reflected
• ​​Customized content​ ​: The goal will automatically trigger the celebration animation immediately

There is a real case: a Southeast Asian stadium picture bought a universal screen at a cheap price, but the player's white clothes reflected, causing the live broadcast screen to be overexposed, and in the end, he could only pull the sunshade network throughout the game. Therefore, sports screens must be customized, just like a jersey needs to be tailored.

​​4. Smart City: Invisible Information Manager​​
LED signs at the hospital registration office and flight information screens at the airport, these inconspicuous screens actually test the technology the most. The secret to the three-year zero failure of the navigation system we made for an international airport is:

• ​​24 hours continuous operation​ ​: The brightness automatically matches the ambient light, and it won't be dazzling in the middle of the night
• ​​Remote cluster management​ ​: The content of 200 screens is updated synchronously in 10 minutes
• ​​Ultra-wide temperature design​ ​: It can work normally between -20℃ and 50℃

Here is a tip: choose the indoor screen and look at the resolution. For screens used in hospitals, the most important thing is grayscale expression, so that the details of X-rays can be clearly displayed. Ordinary advertising screens cannot do this.

After all, choosing an LED screen is like finding a partner - the most important thing is to be suitable. Outdoor advertising should be solid and durable, stage performances should be flexible and varied, and sports events must be customized. Next time you see the shiny screens on the street, you might as well think about the tricks behind it - after all, the value a good screen can bring is far more than the light you see in front of you.
