Knowledge & Support

Cabinet size refers to the physical dimensions of a single modular unit of an LED screen. These cabinets house the LED modules, power supply, receiving card, and other essential components. The standard cabinet size varies depending on the pixel pitch, application scenario, and installation method — for example, P2.5 LED Displays used in indoor environments may come in more compact cabinet dimensions compared to large-scale Solar LED Billboards or Outdoor LED Screens.

1. Understanding Cabinet Dimensions

Cabinets typically range in sizes like  960x960mm, or customized dimensions such as 500x1000mm. In fine pitch LED displays (like COB Micro LED TVs or Indoor LED Displays for conference rooms), smaller cabinets are used to ensure seamless stitching and higher resolution. For outdoor LED applications such as Outdoor Perimeter Banners or stadium LED scoreboards, larger and weatherproof cabinets are preferred for better durability and visibility.

2. Impact on Installation

The cabinet size directly influences:

①Ease of Installation: Smaller cabinets are lighter and easier to handle, suitable for rental LED screens and event staging.

②Structure Requirements: Larger cabinets require stronger steel structures, especially for high-brightness solar LED billboards or truck-mounted LED displays.

③Maintenance Access: Front and rear maintenance options depend on cabinet design, which is crucial for indoor control room LED displays or digital signage in tight spaces.

④Visual Seamlessness: A consistent cabinet size helps avoid visible gaps in Micro LED video walls and COB LED displays.

3. Cabinet Size & Energy Efficiency

Cabinet size also impacts energy usage. A well-optimized aluminum module LED screen with appropriate cabinet sizing reduces heat and power consumption. In solar-powered LED displays or battery-powered LED signage, using compact cabinets supports efficient power management from solar panels and lithium batteries, enabling off-grid and sustainable installations.

4. Applications Based on Cabinet Size

---Small Cabinets: Used in COB LED Displays for conference rooms, Indoor Fine Pitch Commercial Displays, and Luxury Home Micro LED TVs.

---Medium Cabinets: Ideal for retail stores, LED video walls, and command centers.

---Large Cabinets: Common in Outdoor LED Billboards, Solar LED Trailers, Stadium Perimeter Banners, and Energy Storage LED Displays.

In Summary

Choosing the right cabinet size is crucial for balancing visual performance, installation flexibility, energy consumption, and long-term maintenance. Whether you are planning an off-grid solar-powered LED billboard, an interactive LED display for a corporate event, or a micro LED video wall for your business, understanding cabinet size helps you design a more efficient and cost-effective display solution.
