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: 1. This value is not output voltage of inverter.
2. The voltage of inverter must larger than the starting voltage.
