Alas, have you ever been flashed by the giant LED advertising screen in the mall when you are shopping? Or staring at the subway station at scrolling subtitles to see a missed shuttle bus? Let’s talk about how many ways are there to open these luminous "electronic walls"? You may not believe it if you say it. Do you believe it? Even the toilet mirror can turn into an LED screen?

Break the stereotype first

Do you think LED screens can only be hung on the exterior walls of the mall for advertising? That really underestimates it! Last year, I played the project for an island in Southeast Asia:
​• Navigation floor tiles screen on the beach——Automatically display safe evacuation route when high tide
​• Transparent window screen of Tree House B&B——It is glass during the day, but it changes to the top of the starry sky at night
​• Priced electronic scales in seafood market——Weighing and displaying the origin traceability information

The most amazing thing is the conveyor belt screen made for a sushi restaurant in Tokyo. When sushi passes by, 3D ingredients will automatically pop up. The masters all say that since they installed this thing, the number of orders for customers has increased by 30% - it seems that foodies also love high technology!

Metamorphosis of commercial space

​​1. Seventy-two changes in outdoor advertising screens​

• Giant screen on the roof: common but there is a pit - you have to withstand a level 12 typhoon
• Bus stop sign: There is black technology hidden - minus 20℃ still displays clearly
• Gas station ceiling: It is necessary to solve the problem of heat dissipation - the double test of gasoline vapor + high temperature

To give a practical example: the arc screen on a commercial street in Singapore can maintain 4K image quality with a curve of 120°. The secret is to use a spring needle structure at the connection of the box, so even if it expands and contracts, it is not afraid of the picture tear. This screen has been installed for three years and has experienced heavy rain and sunshine. Until now, there is no color difference.

Teammates of the stage performing arts

​2. Secret weapon of performance venue​
• The floor tiles screen must be resistant to stepping—the impact force of the dancer's high heel heel can reach 200kg/cm²
• The background screen can "breathe" - automatically adjust the brightness fluctuations according to the rhythm of the music
• The heartbeat of the air hoisting screen--the weight per square meter must be controlled within 18kg

The circular floor tiles screen made for a certain electronic music festival last year was exciting enough. When DJ plays DJ, the ground screen will vibrate with the bass, but the picture is as stable as an old dog. The secret is that it uses a three-layer shock absorption structure, with a peak load-bearing capacity of 1.5 tons/m² - to put it bluntly, there is no problem with elephant dancing!

Hardcore players in professional fields

​3. The invisible battlefield you cannot see​

• Operating room consultation screen: must pass medical certification, the color difference must be less than ΔE1.5
• Stadium fence screen: IP65 waterproofing is the basis, and it also needs to prevent fans from splashing beer
• Traffic induction screen: Work normally between minus 30℃ and 70℃

There are some considerations for fence screens made for a gymnasium in Seoul. It should be used as a billboard and a safety guardrail. The final plan used a 6mm thick explosion-proof panel, and the actual test was that there were no cracks even when hit by the ice hockey. The most amazing thing is the voice control function - the celebration animation will be automatically triggered when the goal is scored.

Self-question time

​​Q: How long does the LED screen last?​​
It depends on how to use it. Convenience store signs usually last for 5 years, but the control room monitoring screen can last for 8-10 years. There is an airport's flight screen that took 11 years and only changed the power module twice during this period - it is equivalent to "cardiac bypass surgery" for humans.

​​Q: How much does it cost to add a special shape?​​
The price of special-shaped screens such as round and wavy is usually 1.2-1.8 times that of square screens. However, although the circular tunnel screen made for the aquarium last year was 40%, the number of tourists doubled directly - no matter how you calculate this account, it is worth it, right?

Editor's opinion time

If you ask me, choosing an LED screen is like finding a house - you have to think clearly about what you want to do first. The most outrageous case I have ever seen: A hot pot restaurant installed a normal screen in the soup base area, but was shorted three times by steam in half a year. Later, I changed the anti-fog screen and added a pumping slot on the edge of the screen - now I have become an internet celebrity check-in point, and even the spicy soup base shows the temperature in real time on the screen.

When we make plans for our customers, we always ask three questions:

1. What is the most extreme environment in this place? (Storm? Oil stains? Low temperature?)
2. Need to interact with people? (Touch? Voice control? Somatosensory?)
3. What other features do you want to upgrade in five years? (AR linkage? Metauniverse entrance?)

So remember, good screens are not bought, they are “seeded” – they have to be tailored to the usage scenario. Just like the fitting mirror screen we made for a shopping mall in Tokyo, it can be used as a mirror and try on virtual clothes. Now it has driven an average daily sales increase by 17% - this is the live textbook for technology to empower retail!
