Note:
A. If it exceeds MIN/MAX values, then "CCFL Life", "ON/OFF Cycle", and "SAFETY" will not
be guaranteed.
B. CCFL Frequency should be carefully determined to avoid interference between inverter
and TFT LCD.
C. The voltage over specified value (VCCFLi) should be applied to the lamp more than 1
second after startup. Otherwise, the lamp may not be turned on. The used lamp current is
the lamp typical current. The inverter should be able to give out a power that has a
generating capacity of over 1900 voltage.Lamp units need to over 1900 voltage for
ignition.
