Have you ever encountered this kind of embarrassment? When I saw a scrolling transparent screen in a shopping mall, it was so cool, but when I asked about the price, I shivered in fear—the cheap ones were afraid of not being able to use them, and the expensive ones were afraid of being cut off. When I was shopping for a friend last week, a boss bought a transparent screen for RMB 80,000. After three months of installation, color blocks appeared and it looked like a mosaic. Today we will break it up and chat about it, this kind of​ ​moving transparent screen​ ​How should I choose and where is the most reliable place to buy?

1. Must read before buying: These parameters hide great knowledge

First remember this formula:​ ​"Transparency × brightness ÷ maintenance cost = real price/performance ratio"​ ​. Last year, when I was installing screens in a chain milk tea store, I found that for stores with the right parameters, the price per customer directly increased by 15%. When choosing a screen, you must pay attention to these hard indicators:

1. ​​The higher the permeability, the better​​
   The transparency rate of about 86% is just right, allowing you to see the picture clearly without blocking the light. I have seen people who pursue 95% transmittance, but in broad daylight the picture looks blurry like a layer of frosted glass.

2. ​​The brightness will "change the face""​​
   800-1200cd/m² is bright enough for indoor use, but it needs to be over 4000cd/m² for outdoor use. There was a hotpot restaurant owner who bought a low-brightness screen at a cheap price. As a result, when the sun shone at noon, all the promotional information became "invisible text".

3. ​​Don’t compromise on refresh rate​​
   1920Hz is the bottom line. Below this number, the screen will smear when scrolling. Last week I tried a new 3840Hz product, and even the tire lines were clearly visible when playing racing videos.

2. Hidden secrets of procurement channels

​​Offline purchasing three-piece set:​​
① Touch the border seams: The ones with nano-coating feel like baby skin, and the rough ones are definitely knockoffs.
② Look at the arrangement of lamp beads: Lamp beads with positive lighting technology are arranged neatly, while those with side lighting technology tend to have dark areas.
③ Measuring grayscale transition: When playing a video of a cement wall, the appearance of color blocks indicates that the driver chip is stretched.

​​Online pit avoidance guide:​​
✔ Choose a store directly operated by a large factory with a monthly output of over 10,000 square meters
✔ "Lamp Bead Life Test Report" must be provided
✔ Only those that support delivery inspection will be considered

Last year, a customer found a "special price screen" in the wholesale market. It turned out that the driver chip was an old model from five years ago, and the 4K video card played into PPT. Later, I switched to purchasing directly from a manufacturer with fully automated production lines, and the price was saved by 18%.

3. The three most common soul questions asked by novices

​​Q: The price difference is three times. Is the more expensive the better? ​ ​
A: It depends on the scene! If you install it outside the glass curtain wall, you have to spend money to get IP65 protection. If you choose IP54 for indoor display, you can save 40% of the budget. remember:​ ​Every extra penny spent must be heard.​​。

​​Q: How can I avoid being cheated during on-site inspection? ​ ​
A: Let me teach you a trick - let the manufacturer play a segment of "Birds in Slow Motion". Use the 240 frame mode of your mobile phone to shoot, and the wing flapping without blur is the real 4K. If possible, shine a laser pointer on the lamp bead. The one with even reflection is genuine.

​​Q: What should I do if I purchase and install products from other places? ​ ​
A: Nowadays, major manufacturers are using "cloud supervision". Last month, I helped a Xinjiang customer conduct video supervision. The engineer even measured the screw torque on site. You don’t have to worry about logistics, the dedicated line from Shenzhen to Urumqi will reach you within three days.

The editor says something that comes from the bottom of my heart

After working in display equipment for more than ten years, my biggest experience is:​ ​Buying a transparent scroll screen is not buying fast-moving consumer goods. After-sales service is more important than parameters.​ ​. I have seen too many companies choose small workshops to save 20,000 yuan, but the result is that the screen goes out and no one can be found to repair it. Nowadays, reliable manufacturers are engaged in "full life cycle services", from solution design to module replacement five years later.

A final reminder: If you encounter someone who boasts "military quality" but cannot produce CCC certification, or someone who promises "ten-year warranty" but dare not write it into the contract, turn around and leave immediately. remember,​ ​A good screen can be found through testing, not through deception.​ ​. Next time you make a purchase, you might as well ask the manufacturer to play a live broadcast of "The Matrix" - those who can clearly see the flow of code are truly skilled.
