The global LED market contains huge quality differences.
Two screens with similar specifications may perform completely differently after installation.
Common Signs of Low-Quality LED Products
Low-quality systems often show:
- 밝기 불균일
- 색상 변화
- unstable refresh rate
- poor cabinet flatness
- 과열
- weak waterproofing
These problems may not appear immediately, but often become visible after months of operation.
Why Cheap Products Often Create Long-Term Risk
Very low-cost products may reduce quality in areas such as:
- 전원 공급 장치
- 드라이버 IC
- PCB materials
- structural precision
- thermal design
This becomes especially risky in:
- 야외 광고판
- XR 제작
- 지휘 센터
luxury commercial environments
Why Factory Capability Matters
Professional LED factories usually maintain stronger control over:
- calibration
- aging tests
- QC systems
- consistency management
- structural precision

Many low-cost LED products initially look acceptable during short demonstrations.
However, long-term reliability often reveals the true difference between engineering-grade systems and low-end products.
