Hang on. Before you start trying stuff with that VFD display Look at the getter. on the screen there should be a silvery smudge. This is the Getter which helps sustain vacuum in the end of the production run. If this internal smudge is exposed to air due to a display leak it turns into a pale white. I'm asking cause i see a smudge that appears White...altough it may just be the camera. if its indeed white then your display me be broken Anyway.
VFD are vacuum displays. by sending a low voltage trough the Filament (those wires spun accross the display) electrons move through the display. if the correct Grid and Anode are driven with a high-voltage (could be between 10 and 30v) it should work.
Ideally you should look for the datasheet of the display (should be a reference number or something on it somewhere).
You should be able to figure out the Filament pins with a multimeter. The filament pins are the only one with a low resistance between them. dont connect any high-voltage on the filament.
That is a 16 segment 7 digit VFD (Vacuum Florescent Display)
You can use a generic VFD driver or multiplex and it runs on higher voltages than LCDs and LEDs.
You cant just connect it to power and it works.
Here is an Instructable on VFD modules
The OP looks to be using a dumber display than you show in your Instructable though.
Yea When you salvage a VFD you need to do the same thing I did in my Instructable Salvaging LCDs and get the driver IC or reverse engineer it to get the pin outs so you can use a multiplexer.
I got that VFD module for that Instructable for free. I just asked and Nortake gave it to me. Someone said they go for over $100.
They're going to be a bit like driving Nixie tubes.
Vacuum fluorescent need to be handled carefully to maintain the vacuum.
The display can be blue-green or yellow.
it can be multiplexed and needs high voltage drivers ie you cannot simply drive it from uP pins.
These displays "out-gas" meaning they get dimmer with time in use .
That is a vacuum fluorescent display.You will need the driver board for the display if you want to use it.
That's a starburst vacuum fluorescent screen. It probably needs ~30 V to do anything. Any reference numbers on it ?
