I did a simple study of that issue back in 2002, which is findable in the early yahoo group archives. The tubes are 'on' for less time, but the current needs to be somewhat higher for a similar apparent brightness. The tube life is proportional to something like i^-3 for higher currents. With

I never read any evidence in datasheets or elsewhere that tells me multiplexed tubes last shorter than directly driven tubes, despite the somewhat higher current required for similar brightness. Is this really the case? What do you base this on? In LED's, this generally evens out, and the datas

Hi, Fatter digits for big tubes would mean (much) higher current, which is proportional to digit surface. This mean higher power consumption and also earlier end of the tube because of shorts caused by higher amount of sputtered metal from cathodes deposited on insulator rings.. but it is worth of
