Note 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 dis-
play image caused by B/L. Note 2: The waveform of lamp driving voltage should be as closed to a perfect sine wave as possible.’ Note 3: The “Max of kick of
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.
