2.2 Backlight Driving Conditions
Parameter guideline for LED Light Bar Driver under stable conditions at 25°C (Room
Temperature):
Note1. The "LED life time" is defined as the module brightness decrease to 50% orig-
inal brightness so that the ambient temperature is 25°C and typical LED Current at
400mA.
Note 2. The LED driving condition is defined for each LED module (6 LED serial).
Note 3. The variance of LED Light Bar power consumption is 10%. To calculate a
value use this for reference (IL x VL = PLED).
