Core Understanding
Brightness determines how visible an LED display remains under different lighting conditions.
It is one of the most critical specifications for indoor and outdoor applications.
What is Brightness?
Brightness is measured in:
Nits (cd/m²)
Higher brightness means stronger visibility.
Typical Brightness Levels
Application | Brightness |
Indoor Conference | 600–1000 nits |
Retail Display | 800–1500 nits |
Outdoor Advertising | 5000–10000 nits |
Stadium Display | 6500–10000 nits |
