Just bought an LED screen but don’t know who to install it? Last month, a customer sent me a private message, saying that the display screen he bought for hundreds of thousands of dollars had been piled up in the warehouse for two months. He tried to build the frame and broke three modules. This reminds me of the problems that many novices encounter——​ ​You may have purchased the right equipment, but the installation process may overturn the entire project.​ ​. Today we will talk about something practical and teach you step by step how to find a reliable installation team.

Let me first talk about the real thing that happened recently. A friend who works in shopping malls found an LED floor tile screen installed by the decoration team. As a result, the screen went black on the opening day, and later it was found out that the power cord was connected backwards. This is not to scare people. Last year’s industry report showed that​ ​43% of display screen failures occur during the installation and debugging stage​ ​. So, finding the right person is more important than bargaining.

​​How to judge whether the installation team is professional? ​ ​ I have summarized three practical methods:

1. Look at the toolbox: a professional team will at least bring a light meter, signal generator and level calibrator
2. Ask about handling cases: A master who has worked on stadium fence screens is definitely more reliable than one who has only installed advertising screens.
3. Check qualification documents: focus on whether you have a high-altitude working certificate and a low-voltage electrician certificate

Speaking of specific channels for finding people, here is a comparison table to help you avoid pitfalls:

• Personal masters who take orders on e-commerce platforms: The price is low (80-150 yuan per square meter), but they may use second-hand structural parts
• Equipment manufacturers bring their own teams: Although it is more expensive (200-300 yuan/㎡), they are familiar with product features, such as knowing that outdoor screens need to leave gaps for heat dissipation.
• Professional engineering company: suitable for large-scale projects, able to handle lifting equipment and structural calculations

Some friends may ask: "Can I follow the installation tutorial by myself?" " Let's put it this way, last week a customer adjusted the indoor poster screen by himself and set the refresh rate to 3000Hz. As a result, the camera captured all black stripes. ​ ​The key point is: installation is not just about tightening screws, but also understanding optical parameters and signal debugging.​ ​. For example, the brightness of a commercial advertising screen needs to be automatically adjusted according to changes in sunlight, which requires special software settings.

Speaking of specific precautions, let me highlight the following for you:

• Lightning protection testing must be done for outdoor installations, especially in areas with heavy rainy seasons.
• For the quick disassembly and assembly structure of the rental screen, never use ordinary screws instead of special buckles.
• When installing a transparent screen, you must control the ambient light, otherwise the 86% transmittance will be in vain.

Recently, a restaurant owner asked me: "Why do other people's LED walls of the same size have brighter images?" " Later it was discovered that it was an installation angle problem. ​ ​A good installation team will bring a light meter for on-site debugging and adjust the module tilt according to the viewing distance.​ ​, this detail is worth the installation fee.

Finally, a little trivia: Professional installation teams will take the initiative to ask for product manuals. For example, for a display with low brightness and high gray technology, the automatic brightness compensation function must be turned off during installation. If you encounter a master who doesn't ask about technical parameters, it is recommended to replace him directly. After all, the display screen will be used for several years, so the installation step really cannot be compromised.

Editor's opinion: Instead of saving thousands of dollars on installation fees, it is better to find a team that understands the technical parameters. Next time you see a technician who promises to "install it on the same day", remember to ask a few more questions about the cooling plan and signal redundancy configuration to ensure that the unreliable ones can be screened out.
