Alas, many friends from construction companies are asking about this recently - wanting to install transparent screens for buildings, just like wearing glowing clothes on glass curtain walls, but where should I buy this thing? Don’t worry, let’s talk about this thoroughly today!

1. How deep is the procurement channel?

Don’t underestimate the tricks of buying equipment now. Last year’s industry data said: 23% of buyers found that they were cheated after buying the transparent screen! The main thing is to know these three ways:

1. ​Direct purchase by manufacturer​: It’s like looking for the source directly, you can bargain 15%-20%, and you can also go to the workshop to see the production line
2. ​System Integrator​: Package design and installation, suitable for those who are afraid of trouble
3. ​Second-hand replacement platform​: Some exhibitions have been removed from the screen, and the price can be cut in half, but you have to be able to inspect the goods.

To give a real example: Lao Zhang, an office building in Chaoyang District, bought a "special screen" that he found was cheap to find by a merchant. After installing it, he found that the daytime transmittance rate was less than 80%, and the light leaked at night. Later, after inspection, the chips were all in stock from third-tier factories. So,​Buy transparent screen and have to carry a illumination meter to test on site​​, don’t just listen to sales bragging.

2. Why not step on the selection parameters?

You have to remember these hard indicators, which are more important than choosing a son-in-law:

• ​​Permeability ≥85%​: Below this number is like applying a matte film
• ​​Pixel spacing ≤P5​​: Otherwise, it will be all mosaics when you get closer
• ​​Refresh rate ≥1920Hz​​: Pass line without flashing on video
• ​​Brightness adaptation​: Automatic switching between indoor and outdoors is not dazzling

Here is a comparison table for you to review:

3. How to break the price fog?

What do you think? It is also nominally nominally transparent screen, and the quotation can be more than doubled from 3800 to 8800! The main tricks here are:

1. Lamp bead chip: Imported brands are 30% more expensive than domestic ones, but their lifespan is 20,000 hours more
2. Power system: Dual loop redundant configuration is 15% more expensive, but it can prevent sudden black screen
3. Structural material: Aviation aluminum-magnesium alloy box is 25% more expensive than ordinary iron shells

I will teach you a trick to bargaining: take the design plan and ask for a detailed quotation form, and separate the material fees, installation fees and software fees. Last month, I helped my friend bargain, but I just pushed the total price from 1.2 million to 920,000. The key is to find out the 15% "comprehensive service fee".

4. What are the requirements for installation and maintenance?

Here I have to remind you! Last year, a shopping mall in Shanghai completed the screen for three months, but one-third of the modules were burned because of the unreasonable heat dissipation design. Reliable installations must meet these three points:

1. ​​Ventiation and heat dissipation​: Reserved air discharge of ≥0.5 cubic meters per minute per square meter
2. ​Load-bearing accounting​: 30% safety margin must be left on the curtain wall load
3. ​​Inspection channel​: Leave at least 80cm wide maintenance space

There is a special case of practical combat: a hotel in Shenzhen connects the transparent screen with the fresh air system, and automatically starts the cooling mode with a temperature exceeding 26℃. The screen life is estimated to be extended by 3 years. You said this design is endless?

Is the transparent screen easy to break?

It depends on the quality! Last year, the industry report said: The three-year failure rate of transparent screens using first-tier brand chips is less than 5%; while those using miscellaneous chips have a failure rate of 22% in the first year.​​The key is three points​：

1. Protection level is at least IP65 (dust-proof and waterproof)
2. Drive power supply with overvoltage protection
3. Structural parts with wind pressure ≥2000Pa

Let me give you a negative textbook: A popular online bookstore bought screens that were greedy for cheap, but they went on strike in the rainy season. Later, they found that the power box was not moisture-proof at all. The repair fee is almost up to the new purchase price!

If I ask me, buying a transparent screen is the same as decorating a house - don't just look at the surface, you have to spend the money on hidden projects in place. Especially for the cooling system and power module, these two places invest 10% more budget, which can save 30% of the repair costs in the later stage. If you are not sure, remember this formula: "Three tests and three don't buy" (testing reports, project test cases, quality assurance terms; do not buy without after-sales service, do not buy without insurance, do not buy without invoices), keep your care and avoid getting stuck!
