Where are LED full-color displays used? You will understand after reading this

2025-06-01 30


​1. Let’s talk about it first: This thing is really not an ordinary light box

Do you often see giant screens that move in shopping malls and gymnasiums? I may have muttered in my mind: "How much does it cost?" In fact, LED full-color displays are no longer exclusive to the rich. From street shops to international competitions, this thing has long penetrated into every corner of life. But the problem is-​Where exactly do you need to use this high-tech display? Can ordinary merchants afford it?​

LED全彩显示屏到底用在哪?看完这篇你就懂了

To give a down-to-earth example, I went to eat hot pot two days ago and found that there was a display screen that would change color behind the cashier, and the menu and activity information were broadcast in turn. The boss’s wife said to me, “This thing is much more convenient than changing posters, and you don’t have to worry about getting wet on rainy days.” Look, you even use it in small restaurants!


​2. A big understatement of application scenarios: It turns out that so many places are used

1. Three essential scenarios for doing business

​"My store is small, is it too exaggerating to install this?"​ Don’t say that the display is not as big as possible now. The key is to use it:

  • Doorhead advertising​: A 2-meter-wide shop can also install a 1.5-meter-wide bar screen, with automatic brightness adjustment, so you can see clearly under the sun
  • Indoor poster​: Replace traditional light boxes, you can change content on your mobile phone, and change the promotions on holidays at any time
  • ​Interactive display​: A block screen is installed at the door of the fitting room of the clothing store, so customers can see the effect of their outfit when choosing clothes

2. Hard core requirements for professional places​

​"The super large screen of ordinary people in the gymnasium can't use it, right?"​ In fact, the principles are the same, but they are more resistant to creation:

  • The stadium fence is equipped with a display screen, with wide viewing angles, and you have to see the score clearly when you watch the competition area at 160 degrees.
  • The stage floor tiles screen must be able to withstand the singers jumping and jumping, and the load-bearing 2 tons per square meter is the basic operation
  • The outdoor advertising screen is still lit when encountering typhoons and heavy rains, and military-grade protection is standard

​3. Technical information: You have to look at these tricks on good screens​

​"How to judge the quality of the display screen? I feel dizzy when I see the parameters!"​Don't panic, just remember three keywords:

  1. ​"Low bright high gray"​​: Simply put, it is not dazzling at night, it is not white during the day, and it is as smart as the automatic brightness of the mobile phone
  2. ​"Refresh Rate"​: Starting at 1920Hz, you won’t have a scan line when shooting videos
  3. ​"Protection Level"​​: At least IP65 for outdoor use, use a high-pressure water gun to rush it for half an hour

Here is a comparison and you will understand:

  • The power supply must be turned off on ordinary screens on rainy days, and the screen works as usual on rainy days.
  • The color difference starts after using the cheap goods for half a year. Good screens basically do not need to be repaired within the five-year warranty period.

​4. Selection guide: Xiaobai’s pit avoidance manual

​"I heard that the water is very deep, how can I choose a reliable one?"​ Teach you three tricks to prevent deception:

  1. See certification​: ISO9001 is the basics, and CE certification represents exports to Europe and the United States
  2. ​Ask after-sales service​​: Those who dare to promise 24 hours of technical support are considered confident
  3. ​Breaking cases​: Please watch real-life videos of the same type of scene, don’t believe in the effect picture

A friend opened a gym and bought a second-hand screen in a cheap way. As a result, the screen flashed on the day of opening, and the manufacturer had already run away. In the end, I found a home that could provide a five-year warranty. Although it was a little more expensive, it never went wrong in three years.


​5. Global case: Seeing is true

​"It's so awesome, how are you actually using it?"​ Let me give you a few real things:

  • The curved screen of a commercial center in Southeast Asia bent into an S-shaped building, becoming an internet celebrity check-in point.
  • The transparent screens of many subway stations in Japan and Korea can be used as glass curtain walls and broadcast advertisements, both for one and two purposes
  • The fence screen at the international event site is still clear on the rainy days, and the referee's seat can clearly see it

​6. Future trend: It’s not too late to use it now​

​“Will it be too late to enter now?”​ Let me tell you a data: the global digital signage market has grown by 13% every year, and it’s just starting! Today's new technology can make the display as thin as a mobile phone and roll it up and transport it. In another two years, it is estimated that all street milk tea shops will have to come with a display screen as standard.


I have to say that LED full-color display is like the smartphones of the past. At first, I thought it was expensive, but I couldn’t do it when I used it. The key is to find the right manufacturer and don’t buy counterfeit goods with greed for cheapness. Nowadays, reliable manufacturers provide one-stop service from design to installation, and even outsiders like us can easily get started. Do you think this is the reason?
