I have this VFD I got from a car radio (a stock car radio) The circuit board the display is on has a controller right below the display, I managed to read the codes off of the chip, there are three rows of them, i will just put down exactly what it says on them:
DELCO 195
16020889
THAILAND 9645U
There are more codes elsewhere, I will read them:
On the back of the PCB: 019AB599
Picture wise, this is the best I can give you as all I have is my shitty cellphone camera:
Nice VFD.
Unfortunately, the controller IC is a custom one. The only hope of using this VFD outside the radio, will be to connect the VFD PCB to the radio, connect an Logic Analyser on the connections to the display controller IC, and decipher the protofol in use.
I wouldn't go that route for a single display - if i had a bunch, maybe, but it's very time consuming to do that kind of reverse engineering.
Buy an off-the-shelf VFD controller on eBay, hook that up and be happy.
Remember, you need to make an power supply too, around 2-3 volts AC for the VFD heater, and around -20 -30 volts for the segments/grids.
// Per.
Count up the segments you have, maybe something in the
Maxim MAX6922 to MAX6934 series will work for you.
