LED screens must be able to work 24 hours a day and 7 days a week and withstand extremely stormy or sandy storm weather. For manufacturers it is required that the LED screens meet the criterion for outdoor LED screens IP65, and for indoor LED screens IP20. So what do these criterion mean? And what does IP65 and IP20 stand for?
The IP code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating) consists of the letters IP followed by two digits and an optional letter.
As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures of the LED display screens. The standard aims to provide users more detailed information than vague marketing terms such as waterproof.

It's the technical introduction by reading which you will command all the conception in details. But here as a company dedicated in LED display screens, we'd like to be short to avoid any unnecessary mistake.
Front Outdoor LED Screens: IP67
The first digit indicates the protection against dust. And "6" means Dust Tight, which means no ingress of dust and complete protection against contact. The second digit indicates the protection against liquids. And "7" means ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
Back Outdoor LED Screens: IP55
The 2 digits indicate the same parameter with above. But the letters are different. And the first "5" means Dust Protected: Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact. The second "5" means: Water projected by a nozzle against enclosure from any direction shall have no harmful effects.
According to the "The General Criterion For LED Displays": Indoor LED displays should be IP20+, Outdoor LED displays should be IP33+ So with IP67 for the front side, and IP55 for the rear side, we ensure the led display working well in all the outdoor environment and weather conditions.
Clarify On the IP65 LED Screens
Sometimes clients are misled by non-professional suppliers who aim only selling out the led screens. As the reliable partner, we think it's necessary to make clear each confusing point, and be honest with true result. For the front side, it's no difficult to reach "IP65". But for the rear side, as long as there's air inlet and outlet, the protection against dust can't reach "6" - totally prevent the dust. In another words, as long as the heat dissipation design based on fans, the air inlet and outlet is necessary. As a result, the ingress protection can't reach "6".
