Based on what principle? It strikes me as most of the comments here lack a basic understanding of the physics behind electrophoresis. It is an inherently slow process.

a simple google search showed me that you're quite badly mistaken. 5-bit grayscale or 32 levels is widely used. Just google nxp 6sololite 5-bit eink and you'll find "Up to 5-bit pixel grayscale representation" and has been for 5 or 6 years.

We could also have mass-produced electrophoretic sheet (basically the display without the electrodes), that you can "draw" on with any suitable voltage source; you can see someone playing with one in this video and showing how the technology works (and is fundamentally quite simple):
