Large Scale Message Center Vacuum Fluorescent Display for Automotive Applications

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.
