Hi, here is a project I am working on, I am driving the display directly with TPIC6B595 high-powered shift registers and 47ohm series resistors from a 13.8V supply. Average current drawn by the whole display is just over 0.5A. The brightness of the displa

Ah, now i understand you. These are pull up resistors, so that the cathodes are pulled up to 12V to switch off, then driven low by the shift resistor.
If you need constant brightness across each segment you could be individual limiting resistors in betwee
