LED display is an important part of modern display technology, whether in outdoor advertising, indoor display or stage background. In order to better protect and extend the service life of LED display, it is discussed from three aspects: protection grade, flame retardant grade and maintenance method.

Dustproof and waterproof class
IP value can indicate the degree of dust and water protection, IP= dustproof and waterproof level, the first digit after IP refers to the dustproof level, the second digit after IP refers to the waterproof level, the larger the number indicates the higher the level of protection.
Our indoor standard screen is IP20 ("2" refers to preventing the invasion of solid objects with a diameter greater than 12.5mm, "0" refers to no special protection against water or moisture), but like the COB Series LED display can reach IP41 ("4" refers to preventing the invasion of solid objects with a diameter greater than 1mm, "1" refers to preventing the intrusion of water droplets. Water droplets falling vertically, like condensed water, will not cause damage to electrical appliances).
The front of the outdoor standard screen is IP65 ("6" refers to the complete prevention of foreign objects and dust intrusion, "5" refers to the prevention of spray water intrusion, to prevent low pressure water spray lasting at least 3 minutes), the back of the outdoor standard screen is IP54 (IP54 is only for adjustment, "5" refers to the complete prevention of foreign objects intrusion, although it can not completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the appliance. "4" refers to the prevention of splashing water intrusion, to prevent the water from splashing in all directions into the appliance and causing damage). IP54 is enough for outdoor, but the higher IP value means safer. Milestrong's outdoor LED display SN Series can reach IP68. Also, changing the mechanical part makes it easier to pass higher tests.

Flame retardant rating
V-2 rating: After two 10-second combustion tests, the residual flame and flame of the sample must self-extinguish within 60 seconds. At the same time, the droplets can ignite the cotton.
V-1 rating: Also after two 10-second combustion tests, V-1 sample residual flame and residual flame need to be extinguished within 60 seconds. But unlike V-2, its droplets cannot ignite the cotton.
V-0 rating: This is the most stringent rating, requiring the sample to be completely extinguished within 30 seconds after two 10-second combustion tests. In addition, falling particles cannot ignite the cotton.
Milestrong's LED displays are rated V-0 flame retardant so customers can use them with confidence.

Maintenance methods
There are usually two maintenance methods of LED display: front maintenance and rear maintenance, and some LED display supports both maintenance methods. Front maintenance is usually required only when there is no maintenance space behind the screen, and maintenance is performed directly from the front of the screen without going through the back of the screen. In most cases, maintenance is carried out through the back cover of the box, which is the most original and reliable maintenance method, but the condition is that there is enough maintenance space behind the screen body.

When using LED displays, customers can choose the appropriate level of protection according to their different application environments. For example, in the outdoor environment, the LED display needs to have a higher level of protection to resist wind, rain, dust and other natural factors. In the indoor environment, although the requirements are relatively low, it is still necessary to take into account factors such as dust and moisture. In addition, customers should also clean and maintain the LED display regularly in accordance with the maintenance manual provided by the manufacturer. For example, regularly check the display's power and signal connections, clean the surface of the display's dust and dirt, and ensure that the display's cooling system is working properly. By choosing the right level of protection and proper maintenance, customers can not only effectively extend the service life of the LED display, but also ensure the long-term stability and quality of the display effect.
