“It’s mostly about heat, waterproofing, and power stability.”

Outdoor LED displays rely on sealed cabinets and stable internal airflow to survive harsh environments.

Most common weak points include:

  • Power supply failures under high temperature
  • Waterproof sealing gaps around cabinet joints
  • Low-grade LED chips with fast degradation

In field installs, many failures only show up after 6–12 months of real operation, especially in hot or coastal regions.
