While digital signage has not been with us long to put the concept of plasma and LCD screens outside was inevitable given the rapid growth new media. Outdoor digital signage, of course, there are problems, like any type of display has to be protected from the elements.

IP65 and IP66 are often used to describe the capabilities outdoor digital advertising system, such as an LCD or plasma, but the rating system is very bad understood, so exactly what is IP65.

The classification system of intellectual property is a European directive which means' Protection income. "The IP number is used to denote all electrical boxes and the protection offered against any foreign body. There are two digits after the letters of inquiry, the first number indicates protection from solid objects such as dust, dirt and even the fingers, the greater the number the greater the protection.

The second number shows the enclosure provides protection against liquids, again the greater the number the best protection. In our example, outdoor digital signage, IP65 is more commonly used. This is because it offers excellent protection against solid objects (6 suggests that the room is dust-tight and impossible for anyone to make contact with the internal parts using fingers or braces). While the second digit, 5, suggests that while the LCD enclosure can be submerged in water is completely resistant to splash and pressure washing.

Sometimes IP66 is used to describe the protection of outdoor digital signage, offering a little better waterproofing of IP65 although the difference is marginal and denotes the force of water jets that could withstand. Obviously, for any exterior signage LCD enclosure should be protected form the rain rather than jets of water under high pressure.

There is a common misconception about the classification system of intellectual property. It is often assumed that IP is a quality mark - Not. The IP standard is a self-certification system means that anyone can build a liquid crystal compound and claim that is IP65 rated, however, this is no guarantee that the device to operate effectively in the open, even if it means the product was sold with that intention. For any application of outdoor digital signature is better to talk to manufacturers and ask how are enclosures offer protection and that engineering is used in their assembly.
