>As long as e-ink has been around, all I've ever heard were the patent issues. If you're saying it's actually manufacturing difficulties, can you provide any links or additional info? For the record, the "patents" think has no links to back it up either. But to answer your question: E-ink screens are less than $100 (depending on the size), that's already pretty cheap. They're only expensive when compared to LCDs . LC…
Sounds kinda like a problem looking for a solution, you could emagine e-ink taking off for a lot of thing sthat currently are not digital, but it would need to be also cheaper. If e-ink was x100 cheaper, we could use it in x1000 more use-cases
For example? What untapped use cases would be if e-ink displays which can only show B/W images and refresh at 1HZ, unable to show full motion video, and suffer from terrible ghosting, would be cheaper?
I think you're deluding yourself here. Cheaper prices won't magically fix the major limitation of this technology that hinder its expansion outside of its existing niches: e-readers and price tags. All the other display markets have been conquered by LCD, MIP and OLED already because those technologies work better in those cases and e-ink works better where it already is.
