You must have seen the glowing advertising screen installed in the glass wall, right? Last year, a clothing store owner spent RMB 80,000 to renovate the display window. As a result, the transparent screen he installed reflected like a mirror during the day and blinded his eyes when it was lit up at night. In the end, it had to be dismantled and rebuilt. Let's talk today, this kind of​ ​Can transmit light and display​ ​How to choose a reliable special screen?

▂▂▂

​​Let me start with a counter-intuitive conclusion: Don’t just look at the price list when buying a transparent screen.​ ​. There was a restaurant owner who was looking for a bargain and bought a screen that cost RMB 2,000 per unit. However, during the installation, he found that he had to pay extra for wiring and steel structure reinforcement. In the end, the total cost was an extra RMB 18,000. Remember these three fee components:

• ​​Basic screen fee​ ​(55%-60%)
• ​​Structural modification fee​ ​(20%-35%, depending on the wall load-bearing)
• ​​invisible consumption​ ​(10%-15%, including software authorization/spare modules)

Industry data last year revealed that 83% of procurement disputes occurred in the third item. Let me teach you a trick: let the supplier​ ​Five-year maintenance costs​ ​Packaged quotations can avoid 90% of the late price increase traps.

The most outrageous case I have ever encountered: The transparent screen installed in a shopping mall looked normal from the outside, but when I walked inside, I discovered that there were dense shadows of circuits. Later, testing revealed that it was used​ ​Inferior light strip​ ​, the light transmittance of this kind of screen is less than 70% during the day, and there is stroboscopic damage to the eyes at night. tell you now​ ​Three must-check items​​：

1. Use a flashlight to shine through the seams.​ ​Spot uniformity deviation＞15%​ ​Pass immediately
2. Turn on the phone and play a pure white screen, point the phone camera at it to see if there is any​ ​water ripples​​
3. Touch the temperature on the back of the screen, and the temperature difference after 2 hours of operation​ ​more than 8℃​ ​There is a problem with heat dissipation

▂▂▂

I recently checked a project for a friend. The merchant boasted that the screen transmittance rate was 86%, but the actual measurement was only 78%. Teach everyone here​ ​Local testing​​：

• Find a piece of A4 paper and stick it on the back of the screen. From a normal reading distance, you can clearly see the size 5 characters on the paper.
• Standing 3 meters away at 12 noon,​ ​Shadow ghosting does not exceed 2 layers​​
• When the lights are turned off, the screen brightness can be adjusted to 30% to still see the outline of objects behind it clearly.

There is a little trivia:​ ​True high-transparency screen​ ​Almost invisible when the power is off, those with a "screen window effect" are either old technology or use cheap diffusion films.

▂▂▂

Now to answer the core question: Where can I find reliable channels? Let me tell you a real experience - when a convenience store chain renovated 30 stores, it saved a budget of 170,000 by relying on these three tricks:

• Ask suppliers to provide​ ​Actual shooting of the same scene case​ ​(Don’t believe the renderings)
• Sign the contract and indicate​ ​Brightness attenuation compensation clause​ ​(If it exceeds 5% every year, it will be returned to the factory)
• Settlement of payment in batches (leave 20% balance for trial operation for three months)

Special reminder: Don’t be fooled by the talk of “imported chips”. The refresh rate of domestic high-end driver ICs has already exceeded 3840Hz. But we should pay more attention to it​ ​Power module warranty period​ ​, those who dare to promise a five-year warranty are the real ones.

▂▂▂

After handling 137 installation cases, the editor found that those who can​ ​Arrival in 7 days​ ​Suppliers often hide these three tricks:

1. Spliced ​​with engineering leftover materials
2. The control system version is old
3. Lack of lightning protection grounding design
   On the contrary, reliable manufacturers require a production cycle of 10-15 days. After all, there are 18 processes from PCB etching to lamp bead sorting. remember:​ ​The screens that are rushed out are like fast-moving consumer goods and cannot be repaired after a short period of time.​​。

Finally, here is some hard-core data: Choosing the right supplier can extend the screen life from 3 years to more than 8 years, and the average daily cost directly drops from 22 yuan to 7 yuan. When purchasing next time, remember to bring a vernier caliper to measure the distance between lamp beads - if the tolerance exceeds ±0.03mm, don’t hesitate to turn around and leave!
