핵심 이해
A professional LED display system consists of multiple hardware and electronic components working together to deliver stable visual performance.
Understanding the structure of an LED display helps users better select, maintain, and operate LED systems.
Main Components of an LED Display
LED Module
The LED module is the core display unit containing LED lamps, PCB boards, driver ICs, and connectors.
Modules are assembled together to form the full screen.
Cabinet
Cabinets provide structural support and integrate modules, power supplies, and receiving cards.
Common cabinet materials include:
- 강철
- 알루미늄
- 알루미늄 다이캐스팅
- Magnesium alloy
Power Supply
The power supply converts AC electricity into stable DC power for LED modules.
High-quality power supplies improve:
- Stability
- Lifespan
- Energy efficiency
