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.

A large scale graphic vacuum fluorescent display was developed. The display is packaged in a panel size of 54.0 x 350.0 (mm) with 24 x 264 pixels (11 digits when a character consists of 24 x 24 pixels). Self-standing grid system was adopted to make finer grid divisions. To attain uniform luminance and prevent cross talk, the quadruplex anode matrix system was utilized. Wire dampers were used as an anti-vibration measure. To prevent thermal deformation of the grid, glass paste was applied to cover the grid bonding.
