Only about 70 dpi to 150 dpi is needed for signage. But I don't see anything about pixel density or resolution or response time (speed irrelevant for posters).
The Cyan Yellow Magenta must be in layers rather than in side by side of R G B or R G G B Matrix schemes. They'd need clear liquid and C, Y or M balls that are to sides for clear, then front and/or back for colour. The regular eink uses a milky liquid and you see an negative image on the rear as the white & balk balls swap. Early eink had only black balls. In theory layered C Y M is more than 6x brighter than than R G B. 19th C colour slides used R G B starch dots and were very dim compared to later C Y M layered coloured negatives and the cunning colour reversed slides. |

I'm surprised that they aren't also using black.

I'm suspecting the white is actually a white & black layer at the bottom.
I look forward to a proper explanation of the technology used. |

I think I see. With no white pixels on it's sort of like printing on black paper.
Different than CMYK ink printing where K is the black that's mixed in with the CMY. As I remember you can't use 100% of all three of the CMY inks because it makes a soggy mess. And even if you could you still don't get black. Last edited by hobnail; 03-27-2022 at 08:06 PM. |

Here is same link without the Illegal in some places and EU advertising tracker that can deliver malware.
https://www.engadget.com/e-ink-galle...182802114.html It adds almost nothing extra to what we know. |

The tracker seemed to have been an Engadget mistake, gone when last checked.
