The LED screen cabinet is an important unit that makes up the LED display. Because the area of LED screen is relatively large, it can not be transported as a whole, so it will be split into many LED screen cabinets with exactly the same area, and then assembled after being transported to the destination. Next, we will talk about the construction and type of LED screen cabinet in detail.
Structure of LED screen cabinet
A complete LED screen cabinet is assembled with seven major components, which cooperate with each other in order to make the screen light up normally.
Structure Of LED Screen CabinetLED display module
When the LED screen is not lit, we can see from the screen a variety of densely packed LED lamp beads. These LED beads are attached to the LED display module, which can form a variety of different colors after power on.
LED power supply
LED power supply mainly uses constant voltage power supply and wide voltage power supply two kinds. The output voltage of constant voltage power supply usually does not change with the change of load, while the wide voltage power supply can be adjusted according to the change of voltage, so the wide voltage power supply is more suitable for some harsh environments, but the corresponding cost will be higher.
LED display frame
According to the different materials used, divided into iron, die-casting aluminum, magnesium alloy, etc. Among them, iron cabinet and die-casting aluminum cabinet are the most widely used two cabinets, they are usually used for fixed installation and rental installation.
LED receiving Card
The receiving card is responsible for receiving the data transmitted from the sending card, so that the screen can realize a variety of different images. If there is no receiver card in the LED screen cabinet, then the LED display screen can not display a variety of different screens normally.
We usually say debugging screen, in fact, is to adjust the data of the LED receiver card. Common LED receiver card manufacturers are: Novastar, Huidu, Colorlight and Linsn.
Adapter
As we often need to be more than one LED screen cabinet spliced together, so the need to use the adapter will be more than one cabinet data in series. Adapters are mainly two types of power plug and data plug.
Fan
The role of the fan is to generate the cabinet heat out. Fans are mainly oil-containing fan, ball fan, silent fan three, which is widely used because of the advantages of silent fan cheap, long service life, small energy consumption.
Cable and wire
LED screen cabinets need to use a lot of internal wires, such as power cables, long rows of cables, short rows of cables, network cables, HDMI cables and so on.
Summary
As with desktop computers, there are many components that need to be used in an LED screen cabinet, and these components work closely together, without any one of them, it will not be able to run the LED display.
Types of LED Screen Cabinets
The types of LED screen cabinets are actually differentiated based on the material used for the LED screen frame. Currently the mainstream LED screen cabinets or frames, there are mainly the following 5 types:
Iron LED screen cabinet
Iron LED screen cabinets manufactured using sheet metal welding process have strong durability and tolerance, so they are usually used in harsh outdoor environments. The only drawback is that it is more bulky, so the installation requires more than one person to work together at the same time.
Standard Cabinet And Simple CabinetSpecialty LED cabinets come in two types: standard and simple cabinets. Standard cabinet with back cover, waterproof eaves and other designs, waterproof performance is good, mainly for outdoor fixed installation; simple cabinet without back cover, and relative to the standard cabinet, thinner and lighter, so usually used for indoor fixed installation.
Die-casting aluminum LED screen cabinet
Die-casting aluminum LED screen cabinet is the liquid aluminum ingot or aluminum alloy material poured into the die-casting mold, and then through the die-casting machine for die-casting molding.
Die-casting aluminum LED screen cabinetThis cabinet not only has the same strength of iron LED cabinet durability, but also than iron LED screen cabinet is much lighter, can be easily assembled and disassembled, so die-casting aluminum LED cabinet is usually used for rental activities, stage, concerts and other scenes.
Magnesium alloy LED screen cabinet
Magnesium alloy LED screen cabinet’s biggest feature is a strong heat dissipation, it can help the cabinet better internal heat dissipation out, so as to ensure that the cabinet internal components can work properly.
Magnesium alloy cabinet also has a lighter weight, so its application is similar to die-cast aluminum cabinet. In addition, because of its cost is higher than the die-cast aluminum cabinet, the market with less.
Carbon fiber LED screen cabinet
Carbon fiber LED screen cabinet is a kind of lightweight LED screen cabinet, its price is 10-20 times of the iron LED cabinet, 5-8 times of the metal alloy, mainly used in high-end display field, life is not common.
Nano polymer material LED cabinet
It is the lightest of all LED screen cabinets, both transportation and assembly will be more simple. However, due to the immature technology of nanopolymer, the durability is poor, the service life is shorter, and it is not common in the market.
Summary
We have introduced the 5 common types of LED screen cabinets on the market, the current mainstream LED display still uses the first 2 types, the last 3 types are mainly used for high-end and differentiated LED display, not common in daily life.
