Alas, when I was watching short videos recently, I always saw moving product advertisements floating in the shopping mall windows, and the subway station channel suddenly turned into an underwater world - are you also curious about where this black technology is done? The novice Xiaobai wanted to get a transparent LED screen to install a store, but when he searched the Internet, he was full of professional terms, which made people's brain hurt. Don't worry, let's break it up and talk about this matter today.

First understand what kind of transparent screen you want

Last week, I met a boss who opened a milk tea shop and spent a lot of money to install a transparent screen. I found that the reflection during the day was severe and I couldn't see clearly. So, three things you must think clearly before buying:
​​• Install indoor or outdoor? ​ ​ The indoor transmissibility is more than 85% (like the clothing store windows), and the outdoors are able to withstand the sun and rain.
​​• How long does it take to light up every day? ​ ​ Convenience stores may be always bright 24 hours a day, so the heat dissipation structure must be specially designed.
​​• Do you want an interactive function? ​ ​ Some high-end screens can be switched using gesture control

To give a practical example: a certain international airport uses a transparent screen with a temperature control system, and still broadcasts flight information smoothly at minus 20 degrees. This requires a manufacturer that can customize special glass.

Don't step on these pitfalls on the market

The most outrageous case I have ever seen: a scenic spot bought a second-hand screen with a cheap price, but the screen directly evolved into a water curtain cave on rainy days. Here are the key points for you:
​​① Don't believe in the gimmick of "ultra-high light transmittance 90%"​ ​——The screen with an actual transmittance of more than 80% is already like ordinary glass from the side
​​② Beware of splicing seams exceeding 1mm​ ​ The real good screen is almost invisible when you put it together, just like a mobile phone with anti-peeping film.
​​③ The control box must be equipped with intelligent dimming​ ​ Otherwise, you will have to manually change the brightness day and night, and you will be exhausted

A clothing brand installed 300 window screens last year, but it was because it did not require automatic brightness adjustment function. The clerk had to climb the ladder to adjust the parameters eight times every day.

Finding the right place can save ten years of hard work

There are three mainstream procurement channels now:

1. ​​E-commerce platform price comparison​ ​——Suitable for small-area purchases, but remember to let the seller post real-life videos (pay attention to the craftsmanship details of the screen frame)
2. ​​Offline exhibition experience​ ​——Like Shenzhen Optical Expo, you can touch the display effects of different models with your own hands
3. ​​Direct connection with manufacturers​ ​——Especially for custom-made special-shaped screens (such as arc or wavy). Shenzhen has a manufacturer with a monthly output of 10,000 square meters. The anti-smog coating screens made for Japan and South Korea can not turn yellow for three years.

Last year, a chain of convenience stores was ordered directly from manufacturers. From design to installation, they completed 500 stores across the country. The key was that they also trained two technicians.

These parameters are more important than price

You must be most concerned about how much money you are, right? Hold it first, and then take out your wallet after reading these:
​​▶ The refresh rate must be ≥1920Hz​ ​——Otherwise, the fast-moving screen will be dragged, just like watching old-fashioned video tapes
​​▶ Brightness must be automatically adjusted​ ​——800-1200 nits indoors are just right, but outdoors have to reach more than 4000 nits
​​▶ The heat dissipation structure depends on the real thing​ ​——Touch the screen temperature two hours after turning on the computer, some cheap screens can fry eggs

There was a bar owner who bought a screen that was cheap, but when DJ was playing DJ, the screen flashed with the rhythm of the music. In the end, it was discovered that the power module did not meet the standards.

The installation and maintenance path is deep

Do you think it's all done if you buy it? A big mistake! Last year, a shopping mall installed a hanging transparent screen almost hit people because it was not accurate to calculate the load-bearing. Must be aware of:
• Stress testing should be done in advance for the renovation of glass curtain walls
• The power supply line must be independently wired (cannot be mixed with lighting circuits)
• You must use special detergents to maintain every week (there will be water stains when wiped with tap water)

The most amazing thing is a certain automobile 4S store, which makes the transparent screen into a rotating booth, and automatically changes the display angle every half hour - this kind of operation requires on-site debugging by the manufacturer's technical team.

You have to know the price range

Let me give you a brief introduction: the 1-meter x 2-meter transparent screen used in ordinary stores floats between 28,000 and 45,000. But be aware:
✔️ Three-year warranty not included
✔️ Is the control system the latest version
✔️ Is the installation fee calculated separately or the packaging price

A customer found that when comparing the price, A company reported 30,000 yuan and B company reported 36,000 yuan. As a result, when signing the contract, A company suddenly charged an additional software license fee of 8,000 yuan - this kind of routine is hard to defend against.

Editor's opinion

To be honest, buying a transparent LED screen is like finding a partner - you can't just look at the appearance, but also look at the "inner beauty". It is recommended to choose manufacturers who dare to show you project case videos and can provide 24-hour technical support. Recently I heard that some manufacturers launched "use first and pay later" experience service, which is particularly friendly to novices. Remember, a good screen can last for seven or eight years, don’t discount the quality!
