Note 7-1: In order to satisfy the quality of B/L, no matter use what kind of inverter, the output
lamp current must between Min. and Max. to avoid the abnormal display image
caused by B/L.
Note 7-2: The waveform of lamp driving voltage should be as closed to a perfect sine wave as
possible.
Note 7-3: The” Max of starting voltage ” means the minimum voltage of inverter to turn on the
CCFL. and it should be applied to the lamp for more than 1 second to start up.
Otherwise the lamp may not be turned on.
