Outdoor Red
2000 Nit
Outdoor RGB
5000~8000 Nit
Note : Nit = Cd/m2
Calculation example : 10mm pixel pitch, 1 LED for each pixel, red message sign with 2000 Nit request. What is the brightness LED needed?
1. How many LED in each m2 : 100 LED/m x100 LED/m = 10K LED/m2
2. What brightness LED needed : (2000 Cd/m2) / (10K LED/m2) = 200 mcd / LED
3. Customer request for decay concern : 200 mcd / 0.8 = 250 mcd

6. Sign Application Introduction – MKT Strategy
NO for Video Sign
Product performance (chip reliability)
Business entry barrier (bin selection)
Short lead-time (2 weeks)
Prefer application
Bus sign
Long term project
Long lead time
No bin selection
Small message sign (<10M2)
Standard sign in big quantity
Traffic Signal (only R / Y)
