Note 2
Note 1: CCFL Frequency should be carefully determined to avoid interference between inverter and TFT LCD
Note 2: Calculator value for reference (IRCFL×VCFLx2=PCFL)
Note 3: CCFL inverter should be able to give out a power that has a generating capacity of over 1300 voltage.
Lamp units need 1300 voltage minimum for ignition
Note 4: CCFL life time 30,000hr at 8mA,it’s defined as when the brightness is reduced by half.
It’s recommended not to exceed 8.0 mA for CCFL life time concern and it’s prohibited to exceed 8.5 mA for
safety concern.
