How difficult is choosing a glass screen than falling in love?

I just heard that a shopping mall in CBD in Beijing spent 700,000 more money on a curved glass screen. This reminds me of a cold knowledge:​65% of the buyers on the market do not understand the selection methods of different application scenarios​​. Three glass screens that were shut down for maintenance were removed last week, and the cause of the failure was surprisingly consistent - the failure of the waterproof glue strip caused the line to be short-circuited.

The water depth of the procurement channel shallow water

Lao Li, a purchasing manager who traveled around in Huaqiangbei, Shenzhen, did the calculations for me: the price difference between the 10-square-meter glass screen with the same parameters, and the price difference between the three companies is the BYD dolphin. There are three hidden price zones hidden here:

• ​​Engineering quotation​=Basic price × 2.3 (including three-year operation and maintenance)
• ​​Direct sales price of the manufacturer​=Basic price × 1.6 (Logistics must be borne by yourself)
• ​Platform Listing Price​=Basic price × 1.8 (renovated pieces may be available)

I will teach you a trick: the manufacturer needs to issue the "Shipping Test Report" of the month, focusing on the grayscale transition test data. Last year, a batch of problem screens were found by this trick during the acceptance of an exhibition hall in Hangzhou, and 18% of the final payment was cut.

Golden combination of installation parameters

After a landmark mall in Shanghai replaced a new curtain wall, the operation and maintenance cost was reduced by 37%. Their configuration plan is worth referring to:

1. ​​Permeability ≥86%​Ensure natural lighting
2. ​​Surface illuminance difference <15%​(Anti-dizziness)
3. ​​Refresh rate ≥1920Hz​​(Photography without ripple)
4. ​​Seam accuracy ±0.03mm(Breaking light leakage)

Let’s focus on brightness adjustment: models with ambient light sensing can save 28,000 yuan in electricity bills per year. This money is enough to support two cleaning aunties. Do you think it’s worth it?

Three ruthless tricks to accept and avoid pits

I caught a trick when I was inspecting my friend last month - the color temperature difference of the splicing unit exceeded 12%. Remember these must-sees:

• Play pure white picture to measure brightness uniformity (default > 10% directly rejected)
• Use a professional colorimeter to measure ΔE value (>3.0 pass)
• Splash water to test waterproof performance (a small amount of water mist but no beads are hung)

A cinema in Qingdao suffered a secret loss: the grayscale recovery was not measured during acceptance, and the entire screen was purple when "Avatar" was played. Later, I paid an additional 230,000 yuan by reworking, and my heart was regretful.

All veterans in the industry know that buying glass screens is like buying a fine decoration house now - just looking at model rooms is not good, so you have to check hidden projects. I heard that the newly released smart glass screen can automatically adjust the light transmittance, and it is used as a display screen on sunny days and becomes transparent windows on cloudy days. This technology needs to be popularized. It is estimated that the market for curtain wall renovation will shrink by 30% in the next five years. Remember to be more careful when purchasing next time, so as not to suffer immediate losses.
