VFD Driver

For over 30 years LAPIS Semiconductor has been providing high reliability VFD (Vacuum Fluorescent Display) drivers to the US automotive industry. VFDs, developed based on vacuum tube technology, provide a couple of advantages, including excellent visibility by self-luminous, and are being adopted in an increasing number of devices, from audio equipment to home appliances.
