LED Cabinet

LED cabinet is the basic modular unit that clients receive to assemble the led screen panel. But the importance of led cabinet design is easily ignored.
In some clients or even the sales person's opinion, led cabinet is just a unit to housing the small led modules, power supplies, and other components. Indeed, this is the very basic function of the led display cabinet, but the led display manufacturers should consider much further than this. A good led cabinet and a bad led cabinet have almost the same outward appearance, but in the practical operation, the influence to the led screen performance is totally different.
Then, what need to be considered, when design the led cabinet?
Firstly, it should protect the led modules, power supplies, and all the internal components and devices well.

Secondly, it should ensure the safety of the operation, and it must reach the high level ingress protection, without the entry of dust and water.
Thirdly, which is the most important and easily ignored, is the design of heat loop. We say this is most important because most the manufacturers could accomplish the requirements of the above 2 items, but this item requires higher design level.
Following with the long operation time and the temperature of environment, the heat emitting would rise. If the heat couldn't be dissipated efficiently, the led screen quality would be down, and the lifetime would be short.

This sounds very easy to understand but to accomplish a good design, it's not easy at all. The led display manufacturers must pay great attention to it.
A bad designed led cabinet will not influent the led display quality immediately. For a newly installed led screen, it may seem all right. But after a period of running, all the problems will emerge. And this, is very similar with what we call "hidden problem" of led display screens.

At last, when have an RFQ, the clients find "the only difference is the price". But it's better to learn that it is very easy to show words and pictures in email, a good description doesn't mean a good quality. Sometimes, with the reasonable margin, the higher price is of the better quality product. There's not the real famous brands such as Barco, Daktronics in China, the higher price are not for the "brand added value", but for the better material and design.
