Technological Improvements of Vacuum Fluorescent Displays for Automotive Applications

In 1976, Vacuum Fluorescent Displays (VFD) were first used for automotive clocks. Through various technical improvements, VFDs have contributed to the advancement of electronic instrument systems for automobiles. At present, VFDs are the most widely used display device for the automotive market. Current applications include message centers, audio systems, temperature control systems, clocks and Head Up Displays (HUD). This paper reports the technical improvements attained and implemented to date. Latest developments are also included.
