Primary Functions of Cabinets: 1.1 Fixation: Cabinets are used to secure the display screen components, such as modules, unit boards, power supplies, and more. All components must be firmly held inside the cabinet to facilitate the connection of the entire display screen. Externally, cabinets are attached to frame structures or steel structures. 2.1 Protection: Cabinets protect the electronic components inside from external environmental interference, ensuring the safety and reliability of these components.

Classification of Cabinets:

    1. Material Classification: Cabinets are typically made of iron, but high-end options may use materials such as aluminum alloy, stainless steel, carbon fiber, magnesium alloy, and nanocomposite materials.
    2. Purpose Classification: Cabinet classification depends on the usage environment, including waterproof cabinets, simple cabinets, front-opening cabinets, double-sided cabinets, and curved cabinets.

Introduction to Main Cabinets

  1. Introduction to Curved LED Display Cabinets Curved LED cabinets are specially designed for curved screens. Curved cabinets can be categorized into two types: outer curve and inner curve. Generally, curved cabinets have an arc-shaped structure, while modules and unit boards are made of standard materials. The curved shape is achieved through steel structural design to create various curved displays.
  2. Features of Front-Opening LED Display Cabinets for Front Maintenance

In special situations, front-opening LED display cabinets are used to create front-maintenance and front-opening display screens. Their main features are as follows:

Cabinet Structure: The entire cabinet is designed to open from top to bottom through a connection on top. This allows for maintenance and repair of internal components. After installing or servicing the screen, the front side is lowered and locked, providing waterproofing. Application Scenarios: Suitable for outdoor LED displays where a row of cabinets is installed and there is limited space for maintenance at the rear. Advantages and Disadvantages: The advantage is convenient maintenance in situations where there is limited rear maintenance space for the LED screen. The disadvantage is higher manufacturing cost and the use of significantly more power and signal cables between two cabinets than in standard cabinets, affecting communication and power efficiency, and increasing production costs.

  1. Structure of Double-Sided LED Display Cabinets Double-sided LED display cabinets, also known as LED double-sided cabinets, are mainly used for electronic displays where content needs to be visible from both sides. Key characteristics include:

Cabinet Structure: The structure of a double-sided cabinet is like two front-maintenance display screens connected back to back. The double-sided cabinet is also a type of special front-opening structure cabinet, with a fixed structure in the middle and upper halves on both sides that can be lifted up for maintenance. Usage Characteristics: 1. The screen area should not be too large, typically one cabinet per display screen. 2. Mainly installed using suspension methods. 3. Both sides of the display screen can share a single LED control card, often using partitioned control cards. The two sides typically have equal areas and display the same content, only requiring content division within the software.

  1. Trends in the Development of LED Display Cabinets

In recent years, small pixel pitch technology has made significant inroads into the outdoor fixed LED display market, offering superior display quality and better integration with emerging technologies such as 3D, VR/AR, and interactive features for creative expression. This has also opened up new markets, including gas station advertising boards, electronic newspaper boards, bus shelters, and other niche markets where small pixel pitch LED displays were previously unsuitable.

However, the rapid development of small pixel pitch LED displays for outdoor fixed installations has brought about changes in the industry. For example, traditional module materials made of iron have become less suitable due to their weight, poor precision, and insufficient strength, among other shortcomings. New materials for modules have gained increasing attention in the market.

One of the most highly acclaimed materials is "die-cast aluminum."

Die-cast aluminum cabinets have evolved over the years to become lighter, more structurally sound, and more precise, allowing for seamless splicing. The latest die-cast aluminum displays are not merely upgrades of traditional display cabinets; they undergo comprehensive optimization and enhancement in terms of structure and performance. These displays are compact indoor rental screens manufactured using patented technology. The high precision of the cabinet splicing makes assembly and maintenance extremely convenient.

In addition to die-cast aluminum, various new materials have also gained industry attention, such as carbon fiber, magnesium alloy, profiles, nanocomposite materials, and more. Each material has its own advantages:

Carbon Fiber LED Display Cabinets:

Magnesium Alloy LED Display Cabinets:

Nanocomposite Material LED Display Cabinets:

In summary, their common advantages include being lightweight, thin, and easy to install. This represents a future development trend. Clearly, traditional "iron cabinets" are no longer suitable for this trend, and their replacement by better new materials is inevitable. However, it will still be a lengthy process before they are completely phased out of the market, as they currently offer advantages such as lower cost and shorter production cycles (which is precisely where new materials need to make breakthroughs).

Conclusion

As outdoor fixed LED displays gain widespread popularity among customers, their product demands have evolved towards more diverse and personalized requirements. Just as the development of alternative materials for LED display cabinets, although many new materials have emerged, the industry continues to explore other materials with higher reliability and cost-effectiveness. LED display manufacturers must stay vigilant and seize new opportunities for development, actively researching and developing new products, in order to progress continuously and open up new markets.
