High Resolution Analog Vacuum Fluorescent Display

A Vacuum Fluorescent Display (VFD's) is widely accepted as a superior display device because of its impressive self-luminance and high reliability. VFD's for automotive applications have been used to convert signals to visual digital information. Now, in addition to digital style images, analog image displays are being requested for a wider choice of style. Furthermore, bright and clear display appearance and additional function are feasible by adopting the VFD technology to a pointer display application like mechanical speedometers or tachometers. This paper discusses the development of the large scale analog pointer image VFD for automotive use.
