FUTABA VFD DISPLAY DRIVER

Passerby, it seems that you are correct. Components are supplied in the original manufacturer’s packaging, ready for insertion into your machinery. But I don’t have the equipment to drive that at the moment. It is held between an anchor and filament support which apply tension to the wire. The VFD is a display device that has been developed based on vacuum tube principle. Positive voltage applied to the phosphor coated anode attracts electrons which colide with the phosphor and cause light to emit. RoHS Certificate of Compliance.

Zn which operates at low voltage and has green peak wavelength of nm. Robust, reliable and inexpensive.

VFD module

Therefore, it has the advantage of environment resist, high reliability and long life. Those tubes have a pin per display segment, plus the anode and cathode. I’ve never used a VFD before, so this is completely new ground for me.

VFDs have the same structure as vacuum tubes, so it is hardly influenced by external factors. Since then, it’s been lying in my electronics box. RichieACC it may work, barely visible, even from 12v. The phosphor is patterned on the anode in a vacuum package. Thanks for an honest opinion. Save to an existing parts list Save to a new parts list.

When a negative voltage is applied to the grid, electron flow to the anode is cut off. Email Required, but never shown.

I’m even more intrigued now. Phosphor anodes are shaped to desired pattern inside the vacuum tube. The foregoing information relates to product sold on, or after, the date shown below. The VFD is a display device that has been developed based on vacuum tube principle.

Applied screen printing technology is available for patterning. Sign up using Email and Password.

The anode consists of a conductor such as graphite, which is coated with phosphor that is formed into desired graphic pattern. It is held between an anchor and filament support which apply tension to the wire.

RoHS Certificate of Compliance. Each group contains a few elements, the elements share share the pins so for example the 1, 2, Forget it perhaps for another 20 years.

Looks like a raw display, no power or data controller. But these elements will only light up if that common pin has the right voltage AND the group pin has the right voltage. Allowing you to reduce waste and improve production efficiency.

Electrons coliding with the phosphor anode cause it to emit light. But, based on what I’ve been reading, it does seem you have a point.
