¿¿300ppi color eink when??

[galax]

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

Color eInk is not evolving. It's come to a standstill.

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.

You can purchase a 300 PPI colour screen. The issue is that since Gallery 3 has 4 colours of particle (cyan, magenta, yellow, white) in one cell, it is slow to refresh the screen. While Gallery 3 is much improved in speed over the earlier renditions and there was a short lived ereader using a Gallery 3 screen, it is still too slow for ereader use in most people's opinion.

See E Ink Gallery™ 3 for more information.

Gallery 3 = ACeP. It's still uselessly slow for anything other than signage and no sign of it ever getting close to eink speeds, which is is already only marginal. It's still optimistic to claim 1.5s full refresh (1500 ms).

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

Unfortunately, Bigme's Gallery 3 device was a complete disaster, since it was billed as a tablet (including camera, IIRC) and not an e-reader, even though Gallery 3 is nowhere near good enough for a tablet. It's pretty sad, since we need Gallery 3 to succeed so that E-Ink will spend time and money developing Gallery 4. Instead, we're probably going to get Kaleido 4.

Unless Kaledio 4 can give us the full contrast for a BW eInk screen, it's a fail before it's even announced.
