4.4.4 Parameter guideline for CCFL Inverter
Note 1: CCFL standard current is measured at 25±2℃..
Note 2: CCFL Frequency should be carefully determined to avoid interference between inverter and TFT LCD
Note 3: ViCFL means Ignition Voltage for both ends of the lamp, and CCFL inverter should be able to give out a power
that has a generating capacity of over 1810 voltage. Lamp units need 1810 voltage minimum for ignition
Note 4: CCFL operation voltage is measured at 25±2℃.
Note 5: The variance of CCFL power consumption is ±10%. Calculator value for reference (ICFL×VCFL×4=PCFL).
Note 6: Definition of life: brightness becomes 50% or less than the minimum luminance value of CCFL. The typical life
time of CCFL is on the condition at 7.0mA lamp current.
