​​How to avoid being confused by parameters when purchasing transparent screens? ​ ​
Actual measurements in a commercial complex project found that equipment with a nominal 80% permeability rate actually had only 63% permeability. There are three key pieces of data to verify:

• ​​Light strip spacing​ ​(Mainstream 3-10mm) and​ ​Translucent area ratio​ ​relationship
• ​​Power supply method​ ​(The failure rate of centralized power supply is 2.7 times higher than that of distributed power supply)
• ​​Pixel repair rate​ ​(High-quality products must reach above 99.3%)
  It is recommended to ask the supplier to provide​ ​Third-party luminous flux testing report​ ​, focus on the light transmission attenuation value after 5000 hours of continuous operation.

​​What hidden expenses are hidden in material costs? ​ ​
After dismantling the quotation for an airport project, it was found that easily overlooked costs accounted for 28% of the budget:

1. Customized steel structure bracket (about 150,000 yuan/ton)
2. Special cables (high temperature resistant models are 3 times more expensive)
3. Waterproof connectors (the unit price of imported parts is 5 times higher than that of domestic products)
   ​​Choose a prefabricated frame structure​ ​, which can reduce installation labor costs by 40% and shorten the construction period by 18 days.

​​Can you really save money by comparing prices online? ​ ​
Compare the risk index of the two procurement models:
Frequently asked questions in offline channels: design fee accounts for 5%, transportation loss rate is 8%
Potential risks in online channels: false standard rate of parameters: 32%, after-sales response delay of 56 hours
During on-site inspection, remember to lightly scratch the surface of the screen with your fingernails——​ ​A quality diffuser film should have no visible scratches​ ​, which is a direct method to judge the grade of optical materials.

​​What details should be paid attention to during installation acceptance? ​ ​
A certain brand showroom project was reworked due to neglect of three details:

• The distance between power traces and signal lines is <30cm (standard requirement ≥50cm)
• Ground resistance value >4Ω (safety value should be ≤1Ω)
• Joint tolerance＞0.5mm (high-end products require ≤0.2mm)
  carry​ ​Colorimeter measures splice area​ ​, adjustment must be required when the color difference ΔE value is >3.

In a smart building project in the south, engineers found that transparent screens with active cooling systems had a 41% lower failure rate during the rainy season than conventional products. This detail is often overlooked - after working with the back of your hand against the screen for 2 hours, if the temperature exceeds 48°C, be wary of heat dissipation defects. Remember, a truly high-quality transparent screen should be able to "see the content but not the device". When viewed from 15 meters away, the bracket structure should completely blend into the architectural background.
