Alas, recently people always ask me: "Where is it reliable to buy this LED glass screen?" To be honest, there are many products on the market now, and you can see it just by browsing Taobao. But don't worry, let's break it up and talk today--​​How to choose a transparent display that is both beautiful and durable​。

1. Let’s figure it out first: What is this thing?

Let’s give an example first. LED glass screen is like adding a layer of "magic film" to ordinary glass.​​It can be used as ordinary glass to transmit light, and also display high-definition images​​. Nowadays, many shopping mall windows and exhibition hall partitions use this, which does not affect lighting during the day and becomes an advertising screen in seconds at night.

To give a real case: A chain jewelry store installed this kind of screen in a street window, displaying products normally during the day and automatically switched to dynamic advertisements at night. As a result, the passenger flow increased by 40%, which is the "double-sided magic" of transparent screens.

2. 5 things you must know before buying

1. ​Don't be fooled by light transmittance​
   There are those on the market that claim to be 90% light transmittance, which sounds quite intimidating, right? In fact, the physical structure determines​The real light transmittance exceeds 70% will significantly affect the display effect​. For example, we have tested a certain brand of screens with 86% light transmittance, and the picture clarity and light transmittance are the best balance.

2. ​​The brightness depends on the usage scenario​​
   Don't just stare at the highest brightness on the parameter table, it depends on the actual requirements:

• Indoor exhibition hall: 800-1200 nits are enough (too bright will make you dazzling)
• Outdoor window: at least 4,000 nits (it can be seen clearly under the sun)
• Special environment: 500 nits are considered bright in dark places like bars

1. ​​The installation method has hidden secrets​​
   There are two common ones:

• Suspension type: suitable for temporary activities, easy to disassemble but poor stability
• Embedded: Steel structures need to be embedded in advance, which are costly but safer

1. ​After-sales service is more important than price​
   I have seen too many cases of losing money by greed for cheap things. A customer bought a low-priced screen, but the 3 modules were boiled in the rainy season, and the manufacturer had already run away. So​It must be seen if there is a 24-hour technical response​​, it is best to choose one that can provide a 3-year warranty.

2. ​​Certification certificate is not a decoration​
   Products that have truly passed CE/CCC certification have special protection treatments. I will teach you a method of identification: ask the manufacturer to provide certification codes, and you can find out the authenticity by checking it on the official website.

3. Procurement channels that experts only know

Now let’s talk about the key point - where to buy it? There are 3 common ways:

1. ​Direct sales from manufacturers​(Recommended index ★★★★★★)
   There is an advantage of direct connection with manufacturers: the ability to customize special sizes. For example, if a customer wants to make a curved window screen, the non-standard size can also be used in 3 days. Three key points:

• Is there an automated production line (hand welding is prone to problems)
• How much is the monthly production capacity (check for those less than 5,000 square meters)
• Whether to provide installation guidance (the professional team will come to the door for debugging)

1. ​​Projects purchasing agent​(Recommended index ★★★)
   It is suitable for novices who don’t understand technology at all, but pay attention to two points:

• Requires the original authorization letter
• Confirm the ownership of maintenance responsibility

1. ​​Cross-border e-commerce platform​(Recommended index★★)
   Although it can compare prices, the transportation risks are high. LED modules are precision devices, and dark spots may be caused by sea and land bumps.

4. The three most easiest pits to step on during installation

I just helped my friend accept a project last week. If you find these problems, you must pay attention to:

1. ​​Power routing​
   Don't try to save trouble and connect too many modules! There is a shopping mall that has an electric current overload, and the entire screen flashes into a disco-room effect. The professional approach is to install independent power supply for every 6 modules, and lightning protection grounding is required.

2. ​​Heat dissipation design​​
   The most outrageous installation I've ever seen: stuff the control box in a closed ceiling. As a result, the motherboard was burned in high temperatures in summer and the ceiling was removed for repair. The correct way is to leave at least 20cm of cooling space, and also install a rain cover on the outdoor screen.

3. ​Content adaptation​
   Don't think you can use it just by making a video! Transparent screens require special content design, and transparent parts should be left in key areas. Like the plan of a certain car showroom, the front position remains transparent, and dynamic parameters are played in the body part, which directly improves the effect by 200%.

5. Talk about personal experience

After working for so many years, my biggest feeling is:​Buying LED glass screens is not a one-time deal​. Last year, there was a project where the customer said the color display was abnormal at 11 o'clock in the middle of the night. The technical team remotely adjusted the gamma value within 2 hours, and brought the backup module to the door for testing the next day. This kind of full-cycle service is the key.

Now some manufacturers are playing price wars, reducing the thickness of the standard module from 12mm to 8mm, which looks cheap, and the actual heat dissipation and structural strength are discounted.​​It is recommended to choose a product that has undergone 100,000 hours of aging test​​, although it is a bit expensive, it will not cause any problems after five years, which is actually more cost-effective.

After all, choosing a transparent screen is like finding a partner—​​Don’t just look cool, but also look at the inner reliability​. Next time you see the display screen with clear images in the mall, it is mostly done by a professional team. Remember, good products can speak by themselves.
