To meet the demands for "quick installation, lightweight, and high flatness" in the performance industry, mainstream cabinets for LED rental screens have become highly standardized. Currently, the absolute market standard is the die-cast aluminum cabinet, with the predominant sizes being 500×500mm and 500×1000mm.
Weight is a critical factor for rental screens, and the choice of material directly impacts transport efficiency.

Characteristics & Applicable Scenarios |
Market Share |
|---|---|---|
|
Die-Cast Aluminum Cabinet |
The absolute mainstream. Formed via integrated die-casting, it is lightweight (typically 8–12kg per cabinet), high-strength, offers excellent splicing precision, and is ideal for frequent assembly/disassembly. |
>90% |
|
Aluminum Profile Cabinet |
Constructed by assembling aluminum profiles. It is structurally robust, but generally heavier and slightly less precise in splicing compared to die-cast aluminum. More common in cost-sensitive applications or mixed rental/fixed installation scenarios. |
Limited |
|
Iron Cabinet/Sheet Metal |
The lowest cost option, but excessively heavy and prone to deformation. Severely fails to meet the lightweight requirements of modern rental setups, found only in very old stock or the most budget-sensitive markets. |
Essentially obsolete |
Note: While carbon fiber is used in some applications (ultra-lightweight), its extremely high cost makes it a niche, custom high-end product, not a standard market specification.
Cabinet size is often linked to pixel pitch (P value). The following are industry-standard specifications:

Application Scenarios & Features |
|---|---|---|
|
500 × 500 |
P2.9 / P3.91 / P4.81 |
The primary choice for indoor rental. The most versatile "golden size," easily carried by one person, and simplifies area calculation (4 cabinets = 1㎡). |
|
500 × 1000 |
P3.91 / P4.81 |
Preferred for stage backdrops. Larger cabinets enable faster assembly and better overall flatness, ideal for quickly constructing large-area screens. |
|
576 × 576 |
P3 / P4 |
An earlier mainstream specification, still found in existing inventory, commonly used by specific brands or for outdoor rental screens. |
|
480 × 480 |
P2.5 |
Fine-pitch rental screens, used for applications requiring high clarity at close viewing distances, such as conferences and product launches. |
|
640 × 640 |
P5 |
Rental screens for outdoor or long-distance viewing; larger single cabinet area, requires high brightness. |
