How LED Display will perform in extreme cold weather
conditions? How to choose the best LED display screen for cold region?
In
some countries and regions of the world, the temperature is below -30°C for
most of the year, and in some areas, the temperature is even lower. For
example, in some European countries (such as Russia), the historical minimum
temperature is -71°C, and the lowest minimum temperature in North America is
-63°C. In northern my country, Harbin, Changchun and Hohhot are the TOP3
coldest cities in China. Meteorology The extreme low temperature recorded at
the station was -58°C. LED displays in low-temperature areas face tremendous
challenges.
For
LED displays installed outdoors, the various materials that make up the LED
display, such as masks, PCBs, module kits, box frames, etc., will expand and
contract due to their thermal expansion. Coldness in low temperature
environments. Different shrinkage coefficients lead to inconsistent changes in
physical dimensions, which can easily occur:
1. Assembly
Kit Can Break
Extremely
low temperature weather causes components to shrink, but inconsistent shrinkage
of various parts may lead to breakage of the box connection structure,
installation frame or other problems. It is easy to cause some installation
components to break, desolder, etc.
2. Display
Lamp Bead Failure
The
lamp beads on the module will also shrink and desolder, causing display
failure. Internal electronics may also malfunction due to extreme cold
temperatures.
3. Water Leakage
Through Display Cabinet
The
waterproof rubber ring of the box loses its elasticity at low temperatures,
resulting in reduced sealing and increasing the possibility of water intrusion.
Objects
easily become brittle at low temperatures, and LED display products also face
this risk. Use low-temperature resistant materials and equipment, such as
cold-resistant mask and bottom case kit, low-temperature resistant waterproof
glue, low-temperature power supply (can be started in -40°C; -25°C environment):
Use low-temperature-resistant boxes, low-temperature-resistant electronic
equipment and connectors etc. are very important.
Excellent
materials and excellent workmanship are the basic measures to prevent LED
display screens from malfunctioning. The C-Slim high-definition outdoor
advertising screen developed by Chipshow can meet this point.
Three
major measures to protect display cabinet from cold temperature.
1. Material
upgrade
The
all-aluminum bottom shell design has high strength, high heat and cold resistance,
and its performance is greatly improved compared to ordinary iron boxes. The
aluminum material is lighter and easier to install and transport.
2. Mask
upgrade
Innovatively
designed mask with brim height of 2.5mm to improve contrast; the mask has high
precision, low tolerance, and no module phenomenon.
3. Design
Upgrade
It
adopts Chipshow self-developed circuit design and divided voltage power supply
to improve stability. High brightness and good display effect.
