Complete Guide to LED Display Cabinet Types: Materials, Installation & Maintenance Explained
The LED display cabinet serves as the structural and functional foundation of the LED screen system. It houses the LED modules, power supplies, and receiving cards, while providing protection, heat dissipation, and support for installation and maintenance. Choosing the right cabinet type has a direct impact on installation efficiency, operational stability, visual performance, and total cost.
This guide explains the different cabinet types according to material, environment, structure, and service method, helping you make an informed selection for your LED display projects.
1. Classification by Material
Iron Cabinet
Iron cabinets are one of the earliest types used in LED displays. Made from cold-rolled or welded steel plates, they are strong but heavy.

Sealed iron cabinets offer IP65 protection for outdoor use.
Simple iron cabinets are suitable for indoor environments with no waterproof requirements.
Pros: Low cost and high strength.
Cons: Heavy, prone to rust, and less suitable for high-end applications.
Die-Cast Aluminium Cabinet
Die-cast cabinets are formed using precision molds, offering high machining accuracy and flatness.

Lightweight and rust-resistant.
Supports seamless splicing, ensuring uniform visuals.
Ideal for rental screens, exhibitions, stages, and conference rooms.
Easy to install, disassemble, and maintain.
Nano Polymer Cabinet
Made from engineered plastic materials, nano polymer cabinets are lightweight and shock-resistant.
Lower cost compared to metal options.
Easy to transport and install.
Suitable for temporary installations, pop-up displays, and portable screens.
Carbon Fibre Cabinet
A premium cabinet option made from aerospace-grade materials.
Ultra-light (only 9.4 kg/m²) with high tensile strength (1500 kg/m²).
Supports 90° splicing with 45° edge designs.
Fully modular structure allows for fast maintenance and custom installations.
Ideal for sports stadiums, airport signage, large-format outdoor screens, and creative structures.
Magnesium-Aluminium Alloy Cabinet
An optimized material that combines the strength of magnesium with the durability of aluminium.
Magnesium-Aluminium Alloy Cabinet
Excellent thermal conductivity and shock absorption.
Lightweight yet stronger than regular aluminium.
Highly resistant to corrosion, ideal for high-humidity or high-salt environments.
Best for long-running LED installations like command centers, transportation hubs, or roadside billboards.
2. Classification by Installation Environment
Waterproof Cabinet
Features sealed structural design with waterproof gaskets and anti-corrosion finishes.
Rated IP65 or higher, suitable for all-weather conditions.
Commonly used in outdoor applications such as plazas, public signage, roadside LED boards, and building facades.

Simple (Non-Waterproof) Cabinet
Lightweight and cost-effective with a simpler structure.
Used in indoor environments where waterproofing is not required.
Ideal for retail, conference rooms, and interior stage setups.

3. Classification by Structural Design and Display Function
Front-Flip Cabinet
Allows access to internal components (modules, power, cards) via a front-open design.
Suitable for installations where rear access is restricted.
Speeds up routine maintenance.
Double-Sided Cabinet
Designed to display content on both front and back sides.
Used for street lamp pole screens, public info boards, and high-visibility locations.
Maximizes audience engagement from both directions.
Curved (Arc) Cabinet
Enables splicing into inner arcs, outer arcs, wave shapes, or circular displays.
Ideal for immersive exhibition spaces, museum installations, and architectural LED designs.

4. Classification by Maintenance Method
Front-Maintenance Cabinet
Allows servicing of LED modules, power supplies, and receiving cards directly from the front.
Perfect for wall-mounted or embedded displays where rear access is limited.
Common in lobbies, corridors, control rooms, and window-mounted screens.
Magnetic modules or quick-lock mechanisms are often used for fast maintenance.
Rear-Maintenance Cabinet
Requires space behind the display for servicing and component replacement.
Offers more room for cabling, heat dissipation, and layout optimization.
Suitable for large-scale LED walls, stage backdrops, outdoor billboards, and rooftop installations.
Summary: Choosing the Right Cabinet
Application Requirement | Recommended Cabinet Type |
Outdoor waterproof environment | Sealed iron cabinet, waterproof cabinet |
Indoor or short-term use | Simple cabinet, nano polymer cabinet |
Lightweight for rental or transport | Die-cast aluminium, carbon fibre cabinet |
Limited rear installation space | Front-maintenance or front-flip cabinet |
Custom creative shapes or curves | Arc cabinet, carbon fibre with angled edges |
Long-term reliability and durability | Magnesium-aluminium or die-cast aluminium cabinet |
Final Tips
When selecting an LED display cabinet, consider the following factors:
Installation location (indoor or outdoor)
Structural limitations (rear access, mounting type)
Display size and resolution
Maintenance strategy (front or rear)
Budget and long-term operation needs
