VACUUM FLUORESCENT DISPLAY AND FILAMENT DRIVING METHOD THEREOF

摘要

A vacuum fluorescent display (VFD) and a filament-driving method are provided. Two sub-dc voltages having peaks respectively interlaced with each other on the waveform thereof are used to drive the filament. A driving circuit is integrated in the integrated circuit of a VFD driver, a VFD controller or a VFD MCU. The VFD is able to operate without utilizing a transformer.
