What exactly is the requirement for LED displays?

2025-05-30 34

Alas, I wonder if you have noticed that you can see LED screens wherever you go now - hanging on the exterior walls of the mall, rolling in the subway, and even on the counters of the milk tea shop. Why did this thing suddenly become so popular? Today we will talk about where the demand for LED displays came out.

LED显示屏需求到底在哪里?

1. "Electronic Skin" in the City

To be honest, modern cities are like a glowing giant, and LED screens are its skin. Why do you say that? Look:

  1. ​Face project in commercial district

    • The brightness of those advertising screens on the street that are dozens of meters high can reach 4000-7500cd/m², and can still be seen clearly under the sun. I heard that after some business districts installed such screens, the customer flow increased by more than 30%.
    • Nowadays, even milk tea shops are popular with small poster screens. Not only can you change menus at any time, but you can also create some animation effects to attract young people.
  2. ​"Living Map" of Public Facilities​

    • Those scrolling prompt screens in subway stations can instantly become emergency command system when encountering emergencies.
    • The LED screen installed on the stadium fence can not only broadcast advertisements but also display scores. I heard that the protection level is IP65, and I don’t have to worry about heavy rain.
  3. ​Ammoth group of entertainment venues​

    • The floor tiles screen of the disco are now flashing with the rhythm of the music, and there are also interactive effects when you step on it.
    • The theater stage background screen uses low brightness and high gray technology, and the brightness of 800cd/m² can still display 16 bit gray levels.

2. Hard core technology hidden behind demand

At this time, some friends may ask: Why do you have to use LED screens? Isn't traditional displays fragrant? Let's talk with the data:

Demand scenariosPain points of traditional solutionsAdvantages of LED solutions
Outdoor advertisingCan't see clearly in the sun7500cd/m² ultra high brightness
Stage performanceColor fault/drag≥1920Hz refresh rate +16bit grayscale
Traffic InductionHigh maintenance costIP65 protection + remote control
Commercial windowCovering product display86% transparent screen

There is a key breakthrough here—​Low bright high gray technology​. Simply put, the screen can maintain a delicate transition of light and darkness when it is low in brightness. This is especially effective in places such as banks and hospitals that require a quiet environment. Just like the indoor screen used in some high-end places, the brightness can be automatically adjusted to the range of 800-1200cd/m², which is neither dazzling nor clear in detail.


3. Three major promoters of demand explosion

  1. ​Policy is an invisible hand

    • Now that smart cities are being built, many places have directly included LED screen construction in urban planning indicators
    • Environmental protection policies force traditional light box advertising to be upgraded, and LED screen energy consumption is reduced by 30%-50%
  2. ​Technical iteration cannot be stopped

    • In the past, the cost of making a curved screen was extremely high, but now the modular design can allow a 10㎡ screen to be installed in 15 minutes.
    • After the popularity of 5G network, remote control of tens of thousands of screens is as simple as playing with a mobile phone.
  3. ​Consumption habits turn

    • Young people now see static advertisements and take a look, the click rate of dynamic content can be 3 times higher.
    • The "virtual live broadcast room" that brings goods and is popular, behind it is LED background screens supporting the scene

4. Where can I work hard in the future?

Although LED screens are blooming everywhere now, the demand is far from reaching the peak. Let’s talk about some new directions that are visible to the naked eye:

  • Car display​: The sunroof and center console of new energy vehicles are testing the flexible screen
  • Digital Twins​: The factory starts to use LED screens to perform full-process visual monitoring
  • ​The entrance to the metaverse​: AR glasses need to be linked to the real world, and LED screens are indispensable as "coordinate points"

But then again, this industry is not something that can make money by lying down. Now some places have started rolling prices, and I heard that domestic sales fell by 2.56% last year. So, those who can survive in the future will definitely be those who fight hard to fight the technology - just like some manufacturers have achieved pixel spacing to P0.625, which can be used in medical operating rooms.


Finally, I would like to say a few words: LED screens are no longer just "big TVs", they are now more like the city's data interface. From the weather prompts when you go out in the morning to the naked eye 3D advertisements you encounter when shopping at night, this display system is supported by it. Next time you see the LED screen on the street, you might as well take a look at it - maybe you are standing on the "neuron" of the future city.
