I'm trying to start-up on VFDs.

As far as I understand, VFDs have three inputs:

1. Filament
2. Grid (or Common Anode in LED terms)
3. Segments (Anodes in LED terms)

To light up a VFD segment on a digit I have to:
1. Apply filament voltage
2. Apply +v on the display grid
3. Apply +v on the segment

Is it enough to light up a segment or am I missing anything?

Any pointers would be appreciated.

Thanks,
