ITO isn't really transparent... it's pretty yellow (80-95% transmission) and it doesn't carry current well (20-100ohm/sq). You'd be better off with a metal mesh

ITO isn't really transparent... it's pretty yellow (80-95% transmission) and it doesn't carry current well (20-100ohm/sq). You'd be better off with a metal mesh with large pitch electrodes. You're going to need some wires to address the display as well (whether active or passive matrix). With a large pitch Cu or Al conductors you can do 5ohm/sq with good transparency. That will let you do 200nits (candela/m2) with the efficiency of these thin LEDs. ITO would be 10x lower conductance and only works in LCDs because they are inverting voltage light valves (not light sources). If everything worked out you could reasonably view thin LEDs in a dim office environment. That's not really interesting unless it's 3D.
