VACUUM FLUORESCENT DISPLAYS AND DRIVER

Vacuum Fluorescent Displays (VFDs) serve extensively as display devices for consume and industrial products because they offer high visibility, reliability, a long life and other excellent features. VFDs is based on the principle of Low -- energy Cathodoluminescence with the structure of flat panel. The family of VFDs includes numeric, bargraphic, dot--matrix and matrix display. It can provide with number, character (including Chinese character), symbol, graphic and TV imaging. Triode VFD is the main product of this famlily.This paper introduces the mathode of driving as well as the VFD family. Some ICs for driving VFD are also introduced.
