When you plan to purchase an LED display for your outdoor project, the waterproof rating is something you will pay attention to. A waterproof LED display screen can protect electronic components from rain erosion.

But do you know the waterproof rating of LED displays? What do IP65, IP67, and IP68 mean respectively, and what are the differences between them?

This article brings you the ultimate guide to waterproof LED screens. I hope it can help you better understand the waterproof level and protective performance of LED displays.

1. What is The Waterproof LED Screen?

A waterproof LED screen refers to an outdoor LED display that has taken corresponding waterproof measures and has a high waterproof level.

Compared with indoor displays, semi-outdoor or outdoor displays may be affected by weather such as rain due to their outdoor environment.

Therefore, they must have certain waterproof capabilities and reach the corresponding waterproof level to ensure the normal operation of electronic equipment.

Indoor displays do not need to consider the waterproof level. Most of their protection levels are IP54, which has certain dust-proof and moisture-proof capabilities.

The protection levels of outdoor LED billboards include IP65, IP66, IP67, etc. What are the differences between different IP levels? What do the different numbers mean? The answer is revealed below.

2. What is LED IP Rating?

IP (Ingress Protection) is drafted by the IEC (International Electrotechnical Commission). It indicates the ability of electronic equipment to protect against dust and moisture.

(1) The protection level of the LED display is generally shown as IPXY. X indicates the level of dust-proofing and preventing the intrusion of foreign objects into the LED display. The highest level is 6.

(2) Y indicates the degree of sealing of the LED display against moisture and waterproof immersion. The larger the number, the higher the protection level and the stronger the protection capability. The highest level is 8.

Prevent the effects of continuous immersion in water with a depth of more than 1 meter. The exact conditions are specified by the manufacturer for each device.

It can be seen that the waterproof level of outdoor LED displays is generally higher than that of indoor LED displays.

This is because outdoor waterproof LED screens are more likely to encounter rainy days than indoor displays.

For example, the IP65 waterproof LED display can meet the protection needs in most outdoor scenarios. 6 means it can prevent objects and dust from entering the screen. 5 means it can prevent water from entering the screen when sprayed.

If you are in some areas where the rainy season is very long or it rains frequently, a waterproof LED display board with a higher protection level can better meet your needs. Such as IP67, and IP68 outdoor LED boards.

Why should we pay attention to LED display IP ratings? This is because a good protection level is related to the life of the display screen.

High-quality LED raw materials, resistance to external erosion, and subsequent maintenance are all essential.

The waterproof LED screen with good protective capabilities can protect the electronic components inside the screen from rain erosion and extend the service life of the display.
