High Luminance Graphic Vacuum Fluorescent Display for Automotive Applications 940514

The Vacuum Fluorescent Display (VFD) is widely accepted as a superior display device because of it's self luminance and excellent readability. A reconfigurable graphic VFD consisting of 128 X 32 dots, with high luminance, has been developed. It is suitable as a multi function automotive message display. To realize a high luminance and reliable graphic VFD, the improved phosphor material, mechanical construction and driving condition have been studied. This paper discusses these considerations to achieve high luminance.
