In a vacuum fluorescent display tri-compatible dimming system, a dimming signal can be sent in the form of a multiplex bus message, an analog DC voltage signal, or a pulse width modulated signal. Each form of dimming is accepted by a microprocessor of a lighted automotive module, such as a radio, however, the multiplex bus message takes priority. The microprocessor then sends a dimming signal to the vacuum fluorescent display via a vacuum fluorescent display driver IC.
