Recently, a friend who works in shopping mall decoration asked me: "If you want to build a transparent and cool display screen, how can a novice choose one so as not to be disappointed?" "This is the right person to ask! Nowadays, many physical stores want to set up online celebrity check-in points, and government departments want to build smart windows. LED transparent grille screens have suddenly become popular. But to be honest, this thing looks very high-end, and there are a lot of tricks in it...

​​First figure out what this thing looks like​​
You must have seen that kind of display screen that looks like an iron fence, right? It looks like an ordinary fence during the day, but it can actually play advertisements at night! The biggest feature of this screen is that​ ​The light transmittance is as high as 80% or more​ ​, installed in glass curtain walls or windows without affecting lighting at all. To give a practical example - many milk tea shops now make the ordering screen transparent. Customers can watch new product animations while queuing, which can increase the conversion rate by more than 30%.

​​Three hard indicators should be looked at when choosing a screen​​

1. ​​Pixel pitch​ ​: The smaller the value, the clearer it is. For example, P10 (10 mm spacing) is suitable for outdoor advertising viewed from a distance, and P5 (5 mm) is suitable for use in shopping mall windows.
2. ​​Brightness adjustment​ ​: The difference in brightness requirements between day and night is ten times! A good screen can automatically sense ambient light. For example, it can be adjusted to 4000 nits during the day to see clearly, and it can automatically drop to 800 nits at night so that it is not dazzling.
3. ​​Protection level​ ​: For outdoor use, it must be at least IP65 waterproof. In areas like the south where there are many typhoons, special attention must be paid to the sealing of the wiring port.

​​The most common pitfall for novices​​
Last year, a supermarket chain purchased the screen at a cheap price, but after half a year of use, uneven color patches appeared on the screen. Later, tests revealed that the driver chip had cut corners, and the repair cost was three times more than the original savings! Here are the key points:

• Don’t just look at the price, look at whether the manufacturer has a three-year warranty.
• You must see the prototype in person, focusing on whether the white screen is pure.
• Ask about the qualifications of the installation team. Many after-sales problems are actually caused by improper installation.

​​Where is the most reliable place to buy? ​ ​
There is a huge mix of good and bad people on the market now. I suggest you go directly to someone who has​ ​Own factory​ ​of suppliers. For example, there is a factory in Shenzhen that has been exporting for more than ten years. The transparent screens they make for Japan and South Korea are not afraid of typhoons. Focus on these hard conditions:
√ Only manufacturers with a monthly production capacity of over 10,000 square meters can have a guaranteed supply cycle.
√ For those that have passed CE/CCC certification, the quality inspection report must be available for inspection on the spot.
√ The technical team can respond 24 hours a day, especially for commercial projects, which are most afraid of being disrupted at critical moments.

Speaking of the choice of installation location, let me give you a comparison table:

The editor has two final words of caution: Don’t go to a middleman when buying this kind of professional equipment. You can save 20% on middlemen costs by contacting the manufacturer directly. Some manufacturers now support remote debugging guidance, and you can even bring your own installation team to do it. Remember, a good screen coupled with good service is the way to go!
