I wonder how the filament is driven as I see no transformer but two inductors - Did anyone look into how these Noritake displays works power-wise Every VFD display module that I've used has utilized this same basic design... The inductors are part of the voltage convertor and the filament voltages are pulled prior to what would be the final rectification stage in a DC-DC design. So it's an AC signal, but likely a higher frequency. They must be fairly efficient - this display only uses about 200ma in operation and is easily powered by the 5V pin on my usb serial adapter. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
