13 Things About LED Display Cabinet You Have to Know!

For LED display, we know that the most important component is LED module, the quality of LED module directly affects the display effect of the screen. At the same time, the quality of LED display cabinet also has a crucial impact on the installation and maintenance of LED display.

The following article will introduce the cabinet classification, application, and advantages VS disadvantages of LED display in detail.

1. The Main Role of LED Display Cabinet

1. Fixed function: internal fixed module/unit board, power supply and other display components, all components must be fixed inside the cabinet to facilitate the connection of the whole display, external fixed frame structure or steel structure.

2. Protection: protect the electronic components inside from the interference of the external environment, can protect the components, with a good protective effect.

2. Classifications of LED Display Cabinets

1. LED screen cabinet material classification: general cabinet by iron/steel material, high-end as Die-casting aluminum alloy, stainless steel, carbon fiber, magnesium alloy and nano-polymer material cabinet ect.

2. Cabinet usage classification: the main classification is related to the use of the environment, from the waterproof performance is divided into waterproof cabinet, simple cabinet.

From the installation site and maintenance and display performance can be divided into the front turn cabinet, double-sided box, arc cabinet.

3. The Instruction for Traditional Iron/Steel LED Cabinets

As we know that the LED cabinet size should accord with the LED modules` size. The iron/steel cabinet is the initial chose for previous LED display screen. The most advantage for iron/steel cabinet is that the cabinet size can be customized as any sizes.  

1. Ordinary indoor&outdoor

All indoor and outdoor LED displays can use Iron/steelcabinets. Cabinet is according to the CAD that had been designed beforehand, the iron plate shaped by artificial machine tool, different cabinet factories have tiny quality difference becasue of worker skilled degree.

2. Curved LED cabinet 

Iron steel cabinet is specially designed for various curved screens.  The classification of curved cabinet: divided into external curved, internal curved two kinds. And all kinds of special shaped curved screen need steel/iron cabinet.

3.Frontal service LED cabinet

In special occasions, we must use the front turn LED display cabinet to make the front maintenance display screen, the front display screen, its main characteristics are: the whole cabinet by the front and back two halves through the above connection to open the way made.

4. Dual-face LED display cabinet

Double-sided LED display also known as LED dual service cabinet, it`s mainly used in electronic displays that need to be displayed on both sides, such as the pole street LED display cabinet.  

The cabinet structure of the display screen on both sides is equivalent to two front maintenance screens connected back-to-back. The double-sided cabinet is also a special forward structure cabinet. The middle belongs to a fixed structure, and the two sides are connected with the upper part of the middle.

5. The advantages and the disadvantages of iron/steel cabinet


Cabinet of any size can be made according to the size of the module, especially for the curved screen and some special shape screens, only iron/ Steel material can make the final effect according to customer requirements more efficiently and conveniently  


Due to the artificial production of the iron/steel cabinets, the cabinet factory requires mature technology skill.  

At the same time, the material of the iron/steel is prone to deformation and rust caused by temperature and environment changes. If the production process is poor or environment affected, it is likely that the splicing between the cabinets will be uneven, thus affecting the installation and visual effect.  

4. Development Trend of LED Display Cabinet

In recent years, with the advantage of better display effect and better integration of 3D, VR/AR, interactive and other emerging technologies to express creativity, small-pitch technology has actively entered the field of outdoor fixed LED display, and has also continuously opened up a large number of emerging markets.

Such as gas station billboards, electronic newspaper boards, bus stops and other niches where small Spaces were previously unavailable are now widely used.

However, the rapid development of small-pitch LED display in the field of outdoor mounting has brought great changes and improvements to the engineering display industry.

At the same time, we also find some changes that follow:  For example, due to the heavyweight, poor accuracy, strength and other shortcomings of the market based on iron/steel cabinets, there have not been able to keep up with the development of LED display small spacing needs, and some new module materials are increasingly attracting market attention.

Among them, the market is the most popular “die-cast” cabinets.

After several years of development, the weight of die-cast cabinet is lighter and lighter, the structure is more and more reasonable, the accuracy is higher, and the basic seamless splicing can be realized.

The latest die-cast aluminum display screen is not only a simple upgrade of the traditional display box but also a comprehensive optimization and update in terms of structure and performance.

It is a compact indoor rental display screen made by patent, with high precision of box splicing, convenient disassembly, assembly and maintenance.

In addition to die-cast aluminum, many new materials have also begun to attract attention in the industry, such as carbon fiber, magnesium alloy, profile, nano-polymer materials as popular LED displaycabinet replacement materials, they have their own different advantages.

1. Die-casting Aluminum LED display cabinet

Ultra-thin design, lightweight, good strength, tensile resistance of 1.5 tons, the weight of each square meter is only 9.4kg. 

And the use of full modular design, maintenance is more convenient, 45-degree right-angled edge can realize the screen body 90 degrees splicing installation while providing non-transparent backplane, suitable for sports venues, outdoor advertising lights in the field of large installation.

2. Magnesium alloy LED display cabinet

Low density (about 1.8g/cm3 magnesium alloy), high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, impact load capacity than aluminum alloy, organic and alkali corrosion resistance.

The Magnesium alloy used as LED display box has the advantages of high-cost performance, easy installation, excellent heat dissipation, etc.

3. Nano-polymer material LED display cabinet:

It has the characteristics of shock resistance and fall resistance. At the same time, the weight is much lighter than the conventional cabinet.

The weight of a single cabinet is only 4.5kg and 5.1kg. Loading and unloading are simple, handling is light, truss cost is low, transportation cost is low.

Their biggest common advantage above 3 items is that they are light, thin, and easy to install. 

This is the trend of the future, and it is clear that the “iron/steel cabinet” is no longer suitable for this trend, and the future is doomed to be replaced by new and better materials. However, it still needs a long and continuous process to be removed from the market.

Therefore, at present, it has the advantages of low cost and short production cycle (which is exactly where the new materials need to break through at present), and will not be completely abandoned by the market for the time being.
