How to choose a display screen for a cold region?
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.
