If it's like the video linked above (https://www.youtube.com/watch?v=N2V9iuTW3sA https://www.youtube.com/watch?v=N2V9iuTW3sA) it doesn't go straight from Y to C; the "pixel" has to cycle through all the other colours in between.

Maybe some kind of prism that flips one face at a time when it gets a pulse? The other thought that came to mind would be some sort of resonance system... send the right frequency, and the cyan (e.g.) particles bob up and down hard enough to reach the surface, where they'd stick. Each particle would have its own resonance frequency.

  This looks like it may be the patent in question: https://www.google.com/patents/US8797634 https://www.google.com/patents/US8797634

    So in summary, there are two layers. Top has white and magenta, bottom has cyan and yellow. The magenta particles let light through, the others do not. The top layer can put white on top to make white. The top layer can pull all the particles to the side to be completely clear. This allows yellow/cyan/green depending on the state of the bottom layer. The top layer can put magenta on top and white on bottom to make magenta. The top layer can put magenta on top and pull white to the side to be clear magenta. This allows red/blue/black respectively, when the bottom layer is yellow/cyan/green. Edit: But the initial article specifically says "The display utilizes a single layer of electrophoretic fluid" so it sounds like it's using a different tech.

    Hmm, the press release mentions that only " a single layer of electrophoretic fluid" (and also only a single backplane) is employed. Therefore, the mechanism must be a little bit different than the one described in the patent.
