¿¿300ppi color eink when??
Greetings,
The most recent devices and premium ones with color eink come with 150ppi in color mode. I understand that the technology is evolving but I couldn't help wondering if there will be ever 300ppi color eink. ¿Are there any manufacturers testing or developing 300ppi color eink at the moment? ¿What people think is the timeline for 300ppi color eink to arrive? Right now 150ppi color looks quite good, so it's not a bad investment until 300ppi devices appear. Thanks |

As to when, maybe never. That's my guess. |

We have seen no increase in over 11 years in mono eink ppi beyond 300.
A 300 colour would need 600 mono. Kaleido is 4 years old and could have been done in 2005. It's only translucent coloured dots that don't fill the mono pixel. The ACeP is better colour and older, but about 10 times slower. The Kaleido or mono eink is about 150 to 300 slower than other current displays. Mirasol was more than 15 years ago. One product and nothing more. The future is matt LCD and matt QLED. Battery life for reading on some phones and tablets with paper-like LCD or OLED is now comparable to some eink readers. The only future for eink is niche mono dedicated ereaders, unless an new technolgy is discovered/ invented. |

Most Gallery 3 panels are lower than 300 dpi because signage doen't need it. It seems doomed even in retail display market. |
