Note 1 : In order to satisfy the quality of B/L, no matter what inverter is used, the output lamp current must be between

Min. and Max. to avoid the abnormal display image caused by B/L.

Note 2 : The waveform of lamp driving voltage should be as close to a perfect sine wave as possible.

Note 3 : The “Max of starting voltage” means the minimum voltage of inverter turns 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.
