Note 7-3

Note 7-1

In order to have proper operation of the B/L, no matter what kind of inverters, the

output lamp current must be between Min. and Max. values to avoid the abnormal

display image caused by B/L.

Note 7-2

The driving frequency of the lamp may interfere with the horizontal synch signal,

leaving interference stripes on the display. So please evaluate LCD panels

beforehand.

To avoid interference stripes, we recommend to separate as far as possible the

lamp frequency from the horizontal synchronous signal and its high harmonic

frequency.

The inverter which PVI uses is TAD347-1.

Note 7-3

The “Starting Voltage” means the minimum voltage of inverter to turn on the lamp.

And it should be applied to the lamp for more than 1 second to start up. Otherwise

the lamp may not be turned on
