Preserving Your LED Displays in Extremely Cold Weather
Winters have come and apparently a very cold one this time. From December to February, temperature reaches to minus levels.
So, how do LED displays respond when the temperatures are so extremely low?
In general, the rule of thumb for LED screens is that the colder it is, the better it runs. A LED display can run even with a thin frosty layer on it. The reason behind it is that electronic printed circuits and humidity do not mix very well, so ice is better than water. The displays that are made for outdoor use are usually made to sustain any temperatures.
Heat is the enemy of LED's, as it decreases the work efficiency of the bulbs and shortens its lifespan. The cold environment will keep the screen cooled and ensure that the life span is maximized.
Now the question arise to how low can the temperature go before it become an issue?
The problem is that temperature below - 30°C is too much for some components in the LED display system to work properly.
But then, how to protect the displays when the temperature is even lower?
When these displays are working, their components (tiles, control boards and power supplier) heats up. This heat is then enclosed to the metal cabinet of each module. This creates a dry and warm microclimate inside each cabinet that is perfect for the working of LED displays.
Your aim should be to maintain this microclimate. This indirectly means to let LED screen work 24/7. In fact, turning them off at night time is one of the worst things that can be done in extremely cold weather conditions, as it drops its internal temperature dramatically in a very short time.
This poses an indirect damage to the other components and may create problems when you want to turn them on again.
If you cannot have them working 24/7, then you can keep the LED screen in stand-by mode at night time. With this, the screen will actually be alive, but will not display any image. From the outside, you cannot predict the difference between a turned-off screen and a stand-by screen, but this makes a huge difference from inside. In stand-by mode, its components are still alive and produce some heat.
There is one more solution to get the screen in working condition. Try to heat up the cabinets with some electrical heaters and let it warm up for 30 minutes to an hour before you turn on the screen again.
