Abstract
A single glass envelope contains fixed anode segments on the glass surface and a silicon substrate mounted on the same surface. The silicon substrate contains an active matrix vacuum fluorescent anode array as well as serial interface circuitry and a driver circuit for each of the AMVFD and the fixed segment display to minimize the number of input pins in the lead frame of the envelope. Aluminum traces on the glass surface are wire bonded to the substrate and extend to the fixed segments and to the lead frame pins.
