Note 1: CCFL frequency should be carefully determined to avoid interference between inverter and TFT LCD.
Note 2: Calculator value for reference (IRCFLxVCFLx2=PCFL).
Note 3: CCFL inverter should be able to give output a voltage more than 1450 volt. Lamp units need 1450 volt
minimum for ignition.
Note 4: CCFL life time is 30,000hr at 8.0mA, it ’s defined as when the brightness is reduced by half. It ’s recommended
not to exceed 8.0mA for CCFL life time concern and it ’s prohibited to exceed 8.5mA for safety concern.
