You pass by shopping malls and subway stations every day. Have you ever noticed those bright and large screens? They switch to advertisements, news and even interactive games like magic—all of which are the credit of the LED display! But many people may not know that this thing is no longer exclusive to the mall. From the bus schedule you swipe in the morning, to the concert background you watch at night, and even data monitoring in the hospital operating room... LED screens are quietly occupying our lives.
Scene 1: Commercial advertising and information dissemination
The most familiar stranger is the huge advertisement on the exterior wall of the mall. But you may not know that LED screens have evolved to be "invisible":Transparent screen with 86% transmissivityEmbed directly in the glass window, it does not affect the lighting during the day, and becomes a cool display window at night. What's even more amazing is that some screens can automatically adjust the brightness according to the traffic flow - use 4000nit to highlight the eyeballs at 8 o'clock in the morning, and it will drop to 800nit late at night without being dazzling.
In places like airports and high-speed rail stations, LED screens are simply the information center.Small-pitch screen below P4Can display dense flight information and can also connect to traffic big data in real time. There is an interesting phenomenon: after an international airport in China uses LED aeronautical display system, the average road search time for passengers is shortened by 15 minutes, and the probability of error is reduced by 30%.
Scene 2: Culture, Sports and Entertainment and Digital Art
Friends who have chased the concert must have seen the flowing light and shadow on the stage floor, that isDance floor LED floor tiles screen's credit. This kind of screen must withstand the trampling of ten thousand people and also prevent the drink from spilling. What's even more amazing is that with the tracking camera, it can generate light effects that follow the dancers' footsteps in real time - 40% of the stage special effects cost was spent on this last year's tour of a top singer.
Sports venues are even more of LED. The fence screen, scoreboard and circular screen are three-in-one, and even the auditorium handrail has begun to be equipped with interactive small screens. There is a cold knowledge: screens for professional competitionsRefresh rate must be ≥1920Hz, otherwise the high-speed sports football will leave a drag on the screen, and the referee may misjudgment when watching the replay.
Scenario 3: Urban Management and Public Services
When waiting for the red light, staring at the large screen at the intersection to watch the countdown? That is already a basic operation. The new generation of smart traffic screens can adjust guidance information based on real-time traffic flow, and can also be connected with navigation APP data. On a pilot section of Shenzhen, thisIntelligent variable intelligence screenThis has increased the efficiency of traffic during peak periods by 22%.
What is even more unexpected is the medical field. Medical-grade LED screens began to appear next to the shadowless lights in the operating room, specifically used to display patients' vital signs. This screen must doZero delay + zero error, after all, doctors can't wait for the buffering to circle. The actual test data from a Grade A hospital shows that after using professional medical screens, the consultation efficiency of multiple departments has increased by 40%.
Scene 4: Virtual production and immersion experience
The green screen is being replaced by LED walls in the virtual shooting studio that has been popular in the past two years. Imagine: the actor stands in front of the 270° surround screen, and the camera directly captures a well-synthesised spaceship background - this is the new technology used in "The Wandering Earth 3". This studio is usedP1.2 micro-pitch screens below, even the actor's eyelash reflection can be accurately presented.
The museum has also made new tricks. Last year, there was a Han Dynasty cultural relics exhibition, which used LED screen + motion capture to create a "time travel" interactive area. The audience gestures, and the Han figurines on the screen will dance the corresponding dynasty, and the explanation of cultural relics becomes more interesting than watching Douyin.
Technical time control: Why can LED screens replace traditional display devices?
Many people will ask: Don’t projectors and LCD screens taste good? Let's talk with the data:
- Lifespan gap: The ordinary LCD screen is about 30,000 hours, and the LED screen easily exceeds 50,000 hours.
- Energy saving comparison: At the same size, LED power consumption is more than 60% lower than that of projectors
- Environmental adaptation: From the outdoors in the northeast at -30℃ to the tropical construction site at 50℃, the LED screen works as usual
EspeciallySeamless splicing technology, allow LEDs to form any shape. Last year, the main stage of a music festival was made of 576 curved screens to form a spherical stage with a diameter of 18 meters. This kind of operation of traditional equipment could not be done at all.
The future is here: a new way to play you may not think of
Recently, there is a particularly hot trend in the industry—Transparent screen + AR navigation. Imagine: walking in the mall, the glass guardrail in front of you suddenly displays a virtual arrow, and can also mark store discount information in real time. This technology has been piloted in some cities and is expected to be popularized within three years.
There is also a black technology calledXR Virtual Shooting, combine LED screen with virtual engine. There is no need to shoot the whole world when shooting advertisements. You can switch to the Paris Tower and the tropical rainforest in the studio. The key is that the light and shadow effect produced is more than ten times more realistic than the green screen.
Editor's opinion:
I used to think that LED screens were just for advertising, but now I find that they are simply the visual nerve of modern society. From the price list of coffee shops you drink in the morning, to the variety show stage you chase in the evening, to traffic guidance in urgent times... These glowing small squares are redefining the way to "see". Next time you wait for the red light, you might as well observe the screen at the lower intersection carefully - maybe it is making the city smarter in a way that you can't detect.
