When investing in an LED display system, many buyers focus primarily on pixel pitch, brightness, and display quality. しかし, one of the most critical yet often overlooked components is the LED screen cabinet.

An LED screen cabinet serves as the structural foundation of an LED display. It supports LED modules, protects internal electronics, ensures heat dissipation, facilitates maintenance, and directly impacts the overall performance and lifespan of the display.

This comprehensive guide explains everything you need to know about LED screen cabinets, including their components, 材料, 製造プロセス, アプリケーション, 選択基準, and maintenance requirements.

What Is an LED Screen Cabinet?
