How to solve the LED display for low impact

Recently , the temperature also plummeted , for us in terms of outdoor installation , the same difficulties, many of my colleagues hands are frostbitten , but the face of bad weather , we can only look for good weather to step up construction . In dealing with Shanxi LED display, encountered such problems, here want to record their own practices , as we better grasp , handling, outdoor Tsingtek china lcd graphic lcd display module to help.

A , tight , heavy tasks

Estimation of view, there are two weeks came to Shanxi , because the mountainous region located in Shanxi , harsh environment , cold mountain climate, our installation and maintenance personnel is facing a severe test , no way , time , heavy task , only stepping up construction .

Second, the difficulties encountered

We all know that in some cold countries and regions, mostly perennial temperature below 0 ℃, the night even below -30 ℃, LED display in this area , when the ambient temperature is too low , it will not cause the power is turned on the display success. In addition , the composition of the low temperature lcd display a variety of materials because of their different thermal expansion coefficients of variation of its physical size is inconsistent, prone to large gaps between the modules or even squeeze bumps burst , causing the low temperature lcd display waterproof dust failure and apparent mosaic phenomenon . These are the problems we face , we need to resolve one by one .

Third, the solution

1 using low power

End : Japan TDK Power ( ultra-low temperature -40 ℃, conventional -30 ℃)

Taiwan Ming Wei Power ( ultra-low temperature -20 ℃, conventional -10 ℃),

In the end there : Chinese Year of the power ( conventional -10 ℃, low temperature -25 ℃, ultra-low temperature -35 ℃)

Chinese star power ( conventional -40 ℃)

Practice has proved that low power , can also play a good frost, Gwen effect. Here we used the last one.

(2) using anti- cold box

You might ask , cold boxes , there is this ? In fact , the box is made ​​of high quality steel plate, hot -dip zinc cabinet overall process, the cabinet process, the metal surface cleaning sandblasting rust play a role ; oxide coating on the metal surface zinc treatment to prevent surface oxidation and corrosion ; surface paint or grease spraying anti-acid , acid rain, fog effectively prevent erosion .

In general , we need to continue to follow up on the progress of the installation , which in actual maintenance for technical personnel , need more knowledge to understand the job that way .

Well, I hope this trip can be successfully completed in Shanxi , but also want to be able to give some help colleagues , after all, outside year round , but also very difficult for .
