Like in Russia or Canada winter temperature can be as low as -30 degrees below, for LED display many materials have special requirements, such as ordinary power supply below -20 degrees can not start normally, the reason is that the medium in the electrolytic capacitor in the ordinary power supply is liquid, the temperature is lower than a certain value This liquid will become solid, so it can not start normally, so when choosing LED display, you must know the installation location and installation environment of LED display. If the real LED display cannot be started due to too low temperature, specific equipment such as air conditioning or heating equipment is required to raise the temperature, and it can be started normally after the capacitance of the power supply is thawed.
ln addition, LED display is composed of many plastic parts, such as LED module kits, bottom shells, masks, everyone may know that plastic parts are made of new raw materials, there is also a kind of recycling waste materials after treatment and secondary use, some even multiple treatment and utilization of waste plastic raw materials, if LED display plastic parts are made of inferior waste raw materials, the strength of its structure is insufficient, thermal expansion and contraction will be deformed, the consequence is that the surface of the LED electronic screen is uneven, If the LED module has stagnant water, low temperature will cause the LED display module to freeze and crack, so it is recommended to choose plastic raw materials with better materials.
Static electricity is a major killer of LED displays, which will not only reduce the life of the display, but also discharge and break down the electronic components inside the display and damage the screen. Whether it is an indoor LED display or an outdoor LED display, it is easy to generate static electricity during use, causing potential safety hazards to the display. By adding a grounding wire to the display, the static electricity generated by the display can be transmitted to the ground in time; In addition, workers must wear an electrostatic bracelet when operating the display screen to prevent screen damage caused by static electricity carried by the human body.
Condensation is also a huge threat to LED displays, and the harm to outdoor displays is extremely great. Although the outdoor display screen will be waterproof, the condensation is due to the condensation of water vapor in the air, and small droplets will adhere to the PCB board and module surface of the display. If the waterproof treatment is not done, the PCB board and module will be corroded, resulting in reduced or even damaged LED display life. The solution is to choose a display screen with a waterproof coating when purchasing a display.
