Driver circuit for a vacuum fluorescence display
摘要:
A vacuum fluorescence display has a plurality of heating regions and heating inputs corresponding thereto. A driver circuit for the VFD has a driver module with a pulse width-modulatable output connected by way of a distributor to a plurality of heating inputs of the VFD. A switching member is connected between the distributor and one or more of the heating inputs.
