Note 7-7
Note 7-4 : 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 7-5: The lamp frequency may produce interference with horizontal synchronization frequency
from the display, which might cause line flow on the display.
In order to avoid
interference,
the
lamp
frequency
should
be
detached
from
the
horizontal
synchronization frequency and its harmonics as far as possible.
Note 7-6 :Backlight lamp power consumption is calculated by IL×VL.
Note 7-7 : 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.
