digital signage GLOSSARY

Brightness

Brightness is the amount of light a display emits, measured in nits (candela per square meter). In digital signage, brightness is a critical specification: it determines whether content is readable in the deployment environment, from low-light indoor spaces to direct sunlight outdoor.

Brightness ranges by use case:
- Indoor: 300–500 nits.
- Semi-outdoor or window: 1,500–3,500 nits.
- Full outdoor: 4,000+ nits.

Choosing the right brightness avoids both wasted cost (overspecified displays) and visibility failures (underspecified displays in bright environments). Livesignage works with all professional-grade displays across the brightness spectrum.

Use Cases

Brightness selection by environment:

- Retail interiors and corporate offices: 350–500 nits sufficient for most cases.
- Restaurants and hospitality: 500–700 nits to compete with ambient and decorative lighting.
- Window-facing displays: 1,500–2,500 nits, paired with anti-reflective coating.
- Outdoor totems and DOOH: 3,500–5,000 nits with auto-dimming for night conditions.
