Vacuum Fluorescent Display. A popular type of disply found on electronics. It is a type of vacuum tube and was invented in the 1960s before LCD and LED display techology was available.
VFDs are still used today due to their long life, high brightness, ability to display lots of information in a small area and their versatility in color choices. Looks better than most LCD and LED displays as well, thus improving the appearance of a piece of equipment.
Used primarily for status displays on mid range to high end stereos, VCRs, DVD players and other equipment where a good looking display is needed. Can also be seen on cash registers that have deep green or blue readouts.
My stereo has a VFD display.
