I noticed this LED setup in a datasheet for the Kingbright SA40-19EWA. Instead of the leds being in a simple series or parallel setup, each segment of the display has four sets of two leds in parallel, but each set is in series.
I know the lights work, but don't have one of the displays to cut up to confirm that they are actually connected like this. I'm not asking for how this specific part works, but generally, can this wiring setup, as presented, actually work? How does the current flow, how would the voltage drop be calculated? I know some of the users here have simulation software, maybe they can confirm if a simulation of this would work?
