LED Display Brightness Guide for Indoor & Outdoor Projects
Created on 09.10
Introduction
Brightness is one of the key parameters when buying an LED display. Improper brightness will cause poor visual experience, either too dim to see or too bright to produce glare. This article will help you understand LED brightness and select the proper brightness for your project.
- What is LED Brightness?
LED screen brightness is measured in nits (cd/㎡), meaning the luminous intensity per square meter of the display surface.
Higher nits value = brighter screen.
2. Brightness standard for different scenarios
• Indoor LED screen: 400–800 nits
Used for meeting rooms, lobbies, retail shops. Ambient light is soft. Too high brightness will hurt eyes.
• Semi-outdoor LED screen: 1000–2000 nits
For window-facing screens, places with strong indoor natural sunlight.
• Outdoor LED screen: 4500–7000+ nits
Direct sunlight exposure. High brightness ensures clear pictures under sunshine. Our TI-960 outdoor cabinet reaches 7000+ nits.
3. Why brightness matters
- Indoor screen with over-high brightness causes eye fatigue and glare.
- Outdoor screen with low brightness looks dark and invisible under sunlight.
- Brightness also links with power consumption and lifespan. Higher brightness usually consumes more power.
- Tips for choosing brightness
✅ Indoor fixed screen: 500 nits is commonly recommended.
✅ Shop window facing sun: pick 1500–2000 nits.
✅ Outdoor billboard: 5000–7000 nits, strong anti-sunlight performance.
