Note 7-3

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 Kick-off times≧1sec.
