A new constructed display, called BIPLANER vacuum fluorescent display (BIPLANER VFD), has been developed. The biplaner VFD can present information on two surface plane simultaneously. The development is tailored for applications where large quantity of information has to be displayed on a limited surface.

VFD has occupied a superior position as an automotive information display device because of its self emissive high luminance, high reliability, and excellent readability. Recently, most VFD applications have demanded more flexible graphic design capability, reduction of development cost, and short lead time. To respond to these demands, the Universal Grid VFD was developed and mass produced for consumer applications. Taking advantage of its free design capability and unique driving method, Universal Grid VFD was adapted to automotive applications (ECC, ETR, Odo/Trip Meter) and achieved 1700 cd/m2 luminance at 12V and 1/3 duty anode/grid operation. This paper discusses the development of Universal Grid VFD, its characteristics and reliability.

Vacuum Fluorescent Displays (VFDs) have been widely accepted for automotive applications in the U.S. and other countries because of their excellent performance capabilities such as high luminance, high reliability and low voltage operation. Recently, more compact and lightweight VFD packaging has been requested for use in limited-space applications and to achieve smaller overall system size, while concurrently pursuing a higher graphic-to-glass area ratio and maintaining VFD's excellent viewing angle capability. An Ultra Light Vacuum Fluorescent Display (UL VFD) has been developed to meet these challenges which has 14% thinner package thickness and 30% larger available graphic area compared to conventionally produced VFD. This paper discusses the development of UL VFD and its subsequent evaluation and testing.

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.
