I understand the principle of charlieplex and the use of tri-state. What I don't understand is, can I light all segments on a display at once or do I have to light one segment at a time?

Say I have 8 displays in a charlieplex configuration with 8 transistors to select which display I want to use (displays are common-anode).

I turn D0 high to saturate Q1 and turn D1-D7 low to ground all segments, D8->input to 'disconnect' it from circuit. No other transistors should be saturated and LEDs connected to D0 should block the reverse voltage. Display 1 is lit and all others are off? I feel like I'm not understanding something.
