LED Display Autumn And Winter Season Maintenance Guide
LED electronic screen as the most powerful display tool at present, in daily life has been very common, LED electronic screen for high temperature protection requirements, the need for cooling measures, at the same time, LED electronic screen in the cold winter also need maintenance, below we for a variety of environment on LED electronic screen what impact and response measures and communicate with you.
Like in Russia or Canada winter temperature can be as low as -30 degrees below, for LED electronic screen many materials have special requirements, such as ordinary power below -20 degrees can not start normally, the reason is that the ordinary power inside the electrolytic capacitor inside the medium is liquid, the temperature below a certain value of this liquid will become solid, so can not start normally. Therefore, when selecting the LED electronic display, we should know the installation location and installation environment of the LED electronic screen, if the LED electronic screen can not be started because the temperature is too low, it requires specific equipment such as air conditioning or heating equipment to rise the temperature, and it can be started normally after the capacitor of the power supply is thawed.
In addition, the LED electronic screen is composed of many plastic parts, such as LED module kits, shells, masks, we may all know that plastic parts are made of new raw materials, there is also a recycling waste material after treatment and secondary use, some even multiple processing of waste plastic raw materials, if the LED electronic screen plastic parts are made of inferior waste raw materials, its structural strength is insufficient, The result is that the surface of the LED electronic screen is uneven, and if the LED module has water, low temperature will lead to the freezing and cracking of the LED electronic screen module, so it is recommended to choose better plastic raw materials.
Static electricity is a big killer of led display, will not only reduce the life of the display, and even discharge breakdown the internal electronic components of the display, damage the screen. Whether it is indoor led display or outdoor led display, it is easy to generate static electricity during use, causing security risks to the display. By adding a ground wire to the display, the static electricity generated by the display can be transmitted to the ground in time. In addition, when workers operate the display screen, they must wear electrostatic bracelets to prevent the static electricity carried by the human body from causing screen damage.
Condensation is also a huge threat to led displays, and it is extremely harmful to outdoor displays. Although the outdoor display will be waterproof, condensation is due to the water vapor condensation of the air, and small droplets will attach to the PCB board and module surface of the display. If you do not do a good job of waterproof treatment, PCB board and module will be corroded, resulting in led display life reduction or even damage. The solution is to choose a screen with a coated waterproof coating when choosing a display screen.
The low temperature environment will also affect the operation of the led display, most outdoor led display working temperature range is -20 ° C to 60 ° C, the temperature is too low will lead to the activity of some semiconductor components, and even can not start normally, and some plastic components may be frozen because of low temperature. Therefore, when purchasing led display, try to pay attention to its working temperature, do not light the LED screen when the temperature is too low, and regularly check whether the screen is damaged, in extremely cold conditions, you can install a heating device to the display.
LED as a high-value product, although the above situation exists, but not common, but dead lights, deformation and other damage is common. When we buy and use led display, we should not only pay attention to daily maintenance and use specifications, but also to eliminate the hidden dangers of damage at the source, do not covet small and cheap, after all, the temporary cheap will often pay a greater cost. Therefore, when choosing an led display, it is necessary to take full and comprehensive consideration.
