Alas, friends who want to do some high-tech decoration, have you seen the kind of shiny glass wall in the mall? It can be used as a window and broadcast videos, which makes people feel itchy. But when you really have to buy it, the question arises - who should I buy this thing? Could it be that you have to go to the glass factory and the electronics market? Today we broke it apart and said, "I will definitely not be the sucker after reading it."

Sprinkle cold water first

Let me tell you a big truth: Six out of ten companies are second-dea dealers who are calling for photoelectric glass screens. Last year, a restaurant owner was cheated - he bought a "German Technology" glass screen, but the full screen fogged during the rainy season. When he opened it during maintenance, he found that the driver chip was actually an old model three years ago. So,​ ​It's right to recognize these three points​​：

1. Depend on the actual scale of the factory (the monthly output is not 10,000 square meters)
2. Check international certification (CE and CCC are the minimum threshold)
3. Real case videos (preferably installed for two years)

To give a real case: the glass screen at a security check port at an international airport was used for three and a half years without interruption, and its brightness decreased by 12%. This is the real skill. The secret is that the lamp beads used by others are military-grade moisture-proof, and the driver chip comes with temperature compensation function.

Buying channels are very good

​​Online channels:​​
• Industry exhibition official website (this often has the latest technology)
• B2B platform (remember to look at the enterprise certification years)
• Direct connection to engineers in the technical forum (can avoid sales routines)

​​Offline channels:​​
• High-end exhibition hall of building materials market (must touch the physical objects)
• Urban Planning Pavilion Cooperatives (more reliable for government projects)
• Recommended by lighting design companies (they also need to protect their reputation)

There is a very typical story about a clothing store owner. He first compared the price on the e-commerce platform for three months, and finally went to the factory in Shenzhen to watch the orders under the production line with his own eyes. As a result, I found a surprise during installation - the manufacturer directly turned the installation guide into an AR tutorial, and the worker installed it according to the prompts in his glasses, which doubled the efficiency.

How to squeeze the price of water

Let’s look at the comparison of key parameters in the group:

The window screens installed for a duty-free shop in South Korea last year were very particular. The 85% permeability must be ensured during the day and 4500cd/m² brightness must be achieved at night. The final solution is to use a micron-level conductive film + double-sided heat dissipation structure. Now two years have passed, and the average daily work is 18 hours, and the screen has never even had a color spot.

Self-question time

​​Q: How to determine whether the installation team is professional or not? ​ ​
I will teach you a trick - ask them if they dare to change the plan on the spot. A good team toolbox must be available:
• Laser level (Error ≤0.1°)
• Infrared Thermal Imager (Real-time Monitoring of Circuit Temperature)
• Flexible suction cup holder (prevents scratches on the glass surface)

​​Q: How much does it cost to cut special shapes? ​ ​
Let’s put it this way, a regular rectangular screen is like buying ready-to-wear, and a special-shaped screen is high-end customization. The wavy glass screen made for the concert hall last year accounted for 15% of the total price of the mold opening alone, but the effect was really shocking - 38 curved screens made a 270° surround visual effect, and the screen did not vibrate when the speaker was turned on at the maximum.

Editor's opinion time

If I ask me, buying an optical glass screen is like finding a marriage partner. It’s not enough to just look at the appearance (display effect), but also depends on the financial situation (technical reserve). I have seen too many cases. Some people bought low-end versions for cheap, but they had to replace them all in half a year. It was 20% more expensive than buying high-end versions.

When we make plans for customers, the technical team always asks three soul questions:

1. Can this glass withstand the kick of a naughty child?
2. Will there be a strike in extreme weather?
3. Will the system be upgraded in five years?

So remember that reliable after-sales service is more important than anything else. Just like the all-weather response mechanism we prepared for customers, the last time a shopping mall in Japan screened out of the Christmas season, the engineer guided the electricians in the mall to troubleshoot the fault in 15 minutes - this is the real value hidden in the contract terms!
