I have a piece of test equipment that has a cracked VFD (see picture). Replacement VFDs have not been available for a long time. The manufacturer of the VFD is familiar with the part but says it was sole use for this piece of test equipment so not surprisingly I've had no luck sourcing through the surplus marketplace.
The display board talks to the main board over a serial link so I've been pondering making a LCD based replacement, maybe initially prototyping on an Arduino if I can find a compatible LCD.
The actual display area on the VFD is 6-1/2" x 5/8" (256x26 dot matrix). The actual window opening on the case is 7" x 1" and the recessed area behind the window (inside the case) where the VFD fits is 10-1/2" by 3". So there is an option of a larger LCD and only rendering the visible portion.
I've not had much luck finding any suitable sized LCDs that are dot addressable and was curious if anyone had any suggestions?
Thanks!
