​​How should I choose the sky screen so as not to get stuck? ​ ​
For the first time, buyers who have come into contact with the sky screen will be confused by the parameter table. Just like when novices buy cameras, they only look at pixels, many people stare at the brightness value, but only after installing it, they find that the reflection during the day is severe. In fact, there are many tricks here - an engineer from a high-tech enterprise in a certain country revealed that​ ​87% of after-sales disputes are caused by parameter understanding deviations​​。

To give a real case: Last year, the sky screen installed in a commercial complex had a brightness of 7500cd/m², but it was impossible to see clearly when the sunlight was direct at noon. Later I found that this brightness value is data in a specific test environment, and actual use should be considered​ ​Ambient light reflectivity​ ​and​ ​Visible angle compensation​​。

​​Three hard indicators for identifying reliable manufacturers​​

1. ​​Depend on the scale of the production base​ ​: A truly powerful enterprise must have at least tens of thousands of square meters of automation workshops. Factory with a monthly production capacity of over 10,000 square meters are controlled throughout the entire process from SMT patches to aging tests.
2. ​​Check international certification certificate​ ​: ISO9001 is the basic, CE certification represents compliance with EU safety standards, and CCC certification ensures domestic power grid adaptability
3. ​​Try to display the effect​ ​: Use your hands to shake quickly in front of the screen, and the image is not dragged, which is really refreshing. Professional sky screen can achieve dynamic compensation of 0.5ms, and you can clearly see the trajectory of the birds.

Here is a cold knowledge:​ ​Quickly disassemble the box​ ​Now it has become the industry standard. The box with aviation aluminum-magnesium alloy can be controlled within 0.3 mm, and there is almost no gap after splicing. A project has been renovated with a 100 square screen and the whole scene will be completed in 20 minutes. The secret lies in the patented lock design.

​​Installation and maintenance of these pitfalls should be avoided​​
• The waterproof glue plug was not fastened and it was soaked in the rainy season - this happened five times in Southeast Asia projects
• The signal interruption caused by interface oxidation,​ ​Silver ion contact protector​ ​Can extend service life by 3 times
• When the transmission distance exceeds 120 meters, a signal amplifier must be installed. Don’t believe what the salesperson said, “It can be used only if it is used."

A master taught a trick: turn on the slow motion video when accepting, and take a photo of the screen to display a dynamic picture. If there are ripple or faults in the video,​ ​Refresh rate does not meet the standard​ ​or​ ​Not enough grayscale​ ​. This trick is more intuitive than professional instrument detection, and novices can make quick judgments.

​​How to handle special needs? ​ ​
Want the Starry Sky Top effect? Remember to choose​ ​Low bright high gray technology​ ​The screen can still show a 18-bit color depth at 800cd/m² brightness. The sky screen of a concert hall is based on this technology to restore the layering of the Milky Way. If it is an open-air venue, you must choose to bring a​ ​Intelligent photosensitive system​ ​The model can automatically adjust energy consumption according to ambient light, and the average daily power saving is 40%.

Recently popular​ ​Transparent interactive sky curtain​ ​It is really fragrant, with an 86% transmittance that will not affect the lighting of the building. The designer hides the control interface in the steel structure, which is both beautiful and convenient for maintenance. This type of screen has now become a standard commercial landmark. Remember to reserve a double-layer maintenance channel when installing.

Buying a sky screen is a technical job after all, don’t be fooled by fancy concepts. Next time you purchase, you might as well touch the screen body temperature - the working temperature of a real good screen is controlled below 45℃, and 80% of the hot heat dissipation designs are not done well.
