VFD Systems Directly Driven by Single Chip Microcomputer for Automotive Applications

Vacuum Fluorescent Displays (VFD's) are being used widely as the informational display panel in the automobile because they are a self-emissive, high luminance display device that feature crisp and easy-to-read images. This paper reports on the development of a VFD that can be directly driven by the outputs of a single chip microcomputer operating from a 12 volt supply. This system is most ideal for automotive applications.
