Hey, lately I’ve been hearing people say that those light-emitting glass walls in shopping malls are really cool. When I took a closer look—oh! It can actually play videos! Isn’t this black technology a transparent LED display? Don't be in a hurry to place an order, this thing is very deep! Today we are going to talk about something real. I guarantee that after reading this you will know more about it than the person who sells the equipment!

1. What can a transparent screen do? Don’t be fooled by merchants!

​​Question: Isn’t this thing just a piece of glass that emits light? ​ ​
Don't tell me, someone really spent a lot of money to buy it back and use it as a decoration! In fact, the core value of transparent screens depends on the scene:

• ​​shopping mall window​ ​: It displays products normally during the day and turns into an advertising screen at night. I have personally seen a convenience store’s customer traffic increase by 25% after using it.
• ​​Museum showcase​ ​: Directly "stick" the cultural relic introduction video on the glass. An exhibition hall in Beijing used this trick, and the visitor's stay time was doubled.
• ​​stage background​ ​: The artist can come out from behind the screen, and with a light transmittance of over 86%, the visual effect is amazing

​​personal opinion​ ​: Don’t believe the nonsense about “universal screen”! You have to first think clearly about what problem you want it to solve - is it traffic drainage? Or improve your skills? This determines which configuration you want to buy.

2. Three parameters determine wallet thickness

You have to keep your eyes open and look carefully here! Last year, a friend bought a so-called "highly transparent screen" for cheap. As a result, he couldn't see the screen clearly in broad daylight. Why? I didn’t understand the parameters thoroughly!

1. ​​permeability​​：
   Don't listen to merchants bragging about "more than 90%". Only those with actual measured data exceeding 86% are qualified. A restaurant owner complained to me that the screen he bought was transparent enough, but the display effect looked like a mosaic - the pixel spacing was too bad!
2. ​​Pixel pitch​​：
   Available from P3.9 to P7.8, it is recommended to choose P5 or below in retail scenarios. Do you know why the window of a luxury store in Seoul is so clear? The screens they use are P3.9 density screens.
3. ​​Brightness adaptive​​：
   A good screen can automatically adjust the brightness from 4000-7500cd/m², saving 30% of power than manual adjustment! An office building in Shenzhen installed a screen with this function, saving more than 20,000 yuan in electricity bills per month.

3. There are so many installation pitfalls that you can’t imagine

I made a joke last month when I was helping someone inspect the project - the screen was installed, but the power cord was completely exposed! So, buying a screen is just the beginning, installation is the highlight!
​​Details that must be paid close attention to​​：

• Require the manufacturer to issue a structural stress report (especially for suspended installations)
• Ask about the heat dissipation plan. In a shopping mall in Tokyo, poor heat dissipation caused the screen to deform.
• Make sure the wiring is concealed and don’t let the wires ruin the overall aesthetics.
• Test the screen splicing seams. If the gap visible to the naked eye exceeds 1mm, return it immediately.

A customer shared with me his overturning experience: I hired a small workshop to install it cheaply, but the screen overheated and crashed after running for half an hour. Later, I spent an extra 80,000 yuan on rework!

4. Maintenance is really expensive

Do you think that’s it after you buy it? Too naive! The most outrageous case I have ever seen: a certain theater’s transparent screen was used for half a year, and the repair cost was more expensive than buying a new screen!
​​Money Saving Tips​​：

1. Choose a screen with a modular design. If a single module is broken, it can be quickly replaced.
2. Make sure the manufacturer provides 24-hour response service. Don’t wait for the screen to go black before calling someone.
3. When signing the contract, specify the frequency of dust removal and maintenance. It is best to include three years of free service.
4. It is required to provide spare modules, especially those used in key occasions such as concerts.

I heard that a sports venue was very clever. When signing the contract, it asked the manufacturer to send 5% more spare modules. As a result, a malfunction occurred before the start of the game, but it did not affect the live broadcast of the game!

5. Price water can squeeze out a whale

Finally, let’s talk about the most sensitive issue of money bags! The quotations for transparent screens of the same size range from 100,000 to 1 million. There are many ways to do this:

• Aluminum-magnesium-zinc alloy cabinets are 15% more expensive than ordinary materials, but have a service life of 3 years longer
• The one with smart brightness adjustment function is 20% more expensive, but the electricity bill will pay for itself in two years.
• Anti-glare coating requires an extra 8% of the budget, but it is just needed for displaying jewelry, cars, etc.

There is very interesting data: manufacturers that comply with ISO9001 certification generally have a product failure rate that is more than 60% lower. So, it’s easy to suffer a big loss just by looking at the price!

Let me tell you, choosing a transparent LED screen is like looking for a partner - you can't just look at the face, you have to find out the details! For those merchants who are boasting so much, let them use the test reports to speak for themselves. Remember:​ ​A good screen dares to show you a 72-hour burn-in test video, but a bad screen even dodges the boot-up demonstration.​ ​! Next time you meet a salesperson, follow these questions and I will make sure he doesn’t dare to lie!
