Note 8-2 : 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 8-3 : The waveform of lamp driving voltage should be as closed to a perfect sine wave as
possible.
Note 8-4 : This value is not output voltage of inverter.
The voltage of inverter must larger than the starting voltage.
The kick-off time must larger than 1 second.
