IP Rating Grade of LED Screen

IP Rating grade is different for indoor and outdoor LED screens.

IP rating grade depends on the working environment. Outdoor LED screens works in a harsh environment such as rain, snow, hail, fog, and blizzard. Indoor LED screen has a rather mild environment . Therefore, they has different IP grade to protect it from damage.

What is IP Rating or IP Code

The IP rating or IP code classifies the degree of protection provided by an enclosure.  They are defined by the international standard EN 60529 (British Standard BS EN 60529:1992). This standard defines levels of sealing effectiveness against “ingress” i.e. intrusion from foreign bodies such as tools, dirt and liquid water.

What do the two digits in an IP grade mean?

The rating consists of the letters IP followed by two digits, the higher the number the better the protection. Sometimes a number is replaced by X, which indicates that the enclosure is not rated for that specification. Here we use IP65 as an example.

IP65   =  First Digit – Solids

The first digit indicates the level of protection that the enclosure provides against the ingress of solid foreign objects, from tools or fingers that could be hazardous if they came into contact with electrical conductors or moving parts, to airborne dirt and dust that could damage circuitry.

IP65   =  Second Digit – Liquids

The second digit defines the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion etc).

What is the standard for LED screens

Usually, the standard IP rating for outdoor LED screens are IP65 front/IP54 back. However, it requires higher standard, e.g IP67 in some environment. The standard IP rating for indoor LED screens are IP40 front/IP20 back. Also, it requires IP43 for some project.

IP Rating Scale

We hope the screen has a higher IP grade. But does it mean the higher the better? Sometimes, it is yes, but not all. Higher ingress protection means higher cost. In the meanwhile, we need to consider the heat dissipation also. If the screen does not work under the water, there is no need IP67. We do waterproof test for all outdoor LED screens according to its usage. Here are some links for your reference.
