The main function of the cabinet:
Fixed function: to fix the display screen components such as modules/unit boards, power supplies, etc. inside. All components must be fixed inside the cabinet to facilitate the connection of the entire display screen, and to fix the frame structure or steel structure outside.
Protective function: to protect the electronic components inside from interference from the external environment, to protect the components, and to have a good protective effect.
Classification of cabinets:
Material classification of cabinets: Generally, the cabinet is made of iron, and high-end ones can be made of aluminum alloy, stainless steel, carbon fiber, magnesium alloy and nano-polymer material cabinets.
Classification of cabinet usage: The main classification method is related to the use environment. From the perspective of waterproof performance, it can be divided into waterproof cabinets and simple cabinets; from the perspective of installation location, maintenance and display performance, it can be divided into front-flip cabinets, double-sided cabinets, curved cabinets, etc.
Introduction of main cabinets
Introduction of flexible LED display cabinets
A flexible LED display cabinet is a type of LED display that is designed to bend and flex, allowing it to conform to different shapes and surfaces. This flexibility is achieved through advanced engineering and the use of pliable materials, making it possible to create curved, cylindrical, or even spherical displays. These cabinets are composed of lightweight, durable materials that ensure both robustness and ease of installation.
Front-flip LED display cabinet
In special occasions, the front-flip LED display cabinet must be used to make front-maintenance display screens and front-opening display screens. Its main features are: the entire cabinet is made of two halves connected from the top and opened from the bottom.
Cabinet structure: The entire cabinet is like a hinge that opens from the bottom to the top. After opening the bottom, the components inside the cabinet can be repaired and maintained. After the screen is installed or repaired, put down the outer side and lock the buttons. The entire cabinet has a waterproof function.
Applicable occasions: Suitable for outdoor LED display screens, installed with a row of cabinets, and there is no maintenance space behind.
Advantages and disadvantages: The advantage is that it is convenient to repair and maintain the LED screen when there is no maintenance space behind; the disadvantage is that the cabinet cost is high, and when the LED display is made, several times more power cords and cables are used between the two cabinets than ordinary cabinets, which affects the efficiency of communication and power supply and increases the production cost.
Double-sided LED display cabinet structure
Double-sided LED display cabinet is also called LED double-sided cabinet, which is mainly used for electronic display screens that need to be displayed on both sides.
Cabinet structure: The cabinet structure of the double-sided display screen is equivalent to two front maintenance display screens connected back to back. The double-sided cabinet is also a special front flip structure cabinet. The middle is a fixed structure, and the two sides are connected to the upper half of the middle. When maintaining, the cabinet that needs to be repaired or maintained can be opened upwards.
Usage features: 1. The screen area cannot be too large, generally one cabinet and one display; 2. It is mainly installed by hoisting; 3. The two-sided display screen can share a LED control card. The control card uses a partition control card. Generally, the two sides have equal areas and the display content is the same. You only need to divide the content into two identical parts in the software.
Development trend of LED display cabinet
After several years of development, the die-cast aluminum cabinet is becoming lighter, more reasonable in structure, and more precise, and can basically achieve seamless splicing. The latest die-cast aluminum display is not just a simple upgrade of the traditional display cabinet, but has been comprehensively optimized and updated in terms of structure and performance. It is a compact indoor rental display made with patents, with high cabinet splicing precision, and extremely convenient disassembly and maintenance.
