How does this kind of display actually work? I mean how does it transport the different colors to the front of the pixels while still keeping them separate? The

  To an attempt of reconstructing the idea through available information some months ago, ACeP works through "voltage switch tricks over different sized and charged particles in the microcups". The so-called "waveforms" that optimize the workings of traditional E-Ink panels, in this case seem to be something like - just inventing some imaginary "recipe" - "a big shock on the cathode followed by a series of short tickles on the anode tends to place the larger sized and strongly negative charged particles above the (etc.)". The producers have also declared that there is a lot of "heuristic attempting" before defining the "waveforms" (as recipes to make a class of pigmented particles go in the right position).

    I read this as "the particles differ in size and charge" then somehow through some fiddly electrical impulse magic they are separated and can be sorted to be deposited on the front somehow.

      Yes. Sequences of «fiddly electrical impulse[s]». "Make it so it gives some momentum to these, then pull a bit those..." - again, attempting a sketchy description of the "waveforms". Edit: by the way: I would not say that 1-pigment E-Ink is that «straight-forward»: tricks like the 'Regal' waveform, abatement of ghosting (etc.), were not born immediately.
