#A VFD operates on the principle of cathodoluminescence, roughly similar to a cathode ray tube, but operating at much lower voltages. Each tube in a VFD has an anode coated phosphor that is bombarded by electrons emitted from the cathode filament. In fact, each tube in VFD is a triode vacuum tube because it also has a mesh control grid.

The first VFD was the single indication DM160 by Philips in 1959. The first multi-segment VFD was the 1962 Japanese single-digit, seven-segment device. The displays became common on calculators and other consumer electronics devices. In the late 1980s hundreds of millions of units were made yearly.#
