What is bistability in this context? Confidence that the ink will rest in 'on' or 'off' configurations? How does that relate to greyscale with multiple configu

  Clearink does not rely on the foreground pigment particles coming to "rest" at a fixed position relative to the background pigment, ie: achieving a stable state. Instead they rely on driving the field for as long as the foreground is needed. As soon as it decays, the background pigment instantly rises back to the internally reflecting top plane. This allows the display to achieve much faster speeds since the pigments can be optimized for speed rather than stability.

    From what this description sounds like, the foreground pigment would only remain at the forefront so long as a charge was applied. Doesn't this defeat the energy savings of eInk in that once you have updated the display it doesn't cost anything to hold its image?

      Yes, it would lose the image once the display is no longer driven. The main attraction is the removal of the need for a backlight and the sunlight readability and all the other advantages that come from using actual pigments.
