Note 7-6

Note 7-3 : The back-light driving waveform should be as closed to sine-wave as possible.

In order to satisfy the quality of B/L , no matter use what kind of inverter , the each output lamp

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

Note 7-4 : The “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.

Note 7-5: Lamp current is measured with current meter for high frequency as shown below
