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 SIN wave as

possible.

Note 7-3 : The” Max of starting 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.

Backlight driving connector: JST BHR-03VS-1 , 3 Pins, Pitch : 4 mm
