Or maybe a color E-ink ?

Short response: Colour eink is pointless for reading novels.

Longer answer: This is why it's only for comics and signage.
Colour eink needs a front light except outdoors. There are two basic technologies:

1: The filter kind (Triton, Kaleido) is either dark or pastel and about 4000 shades/hues with reduced resolution. OK for comic books outdoors. It's mono eink with an RGB filter on top, so either you get full resolution in one axis and one third on the other axis, or you have half resolution on both axis. The filter may gradually fade in bright sunlight (the ones on LCD panels do).

2: The coloured cell kind (Gallery Acep) is up to 1.5 seconds to turn a page and about 30,000 shades/hues (in slowest mode). Really for shop signage. It's got an unpleasant flicker turning a page. Page turning takes a lot more power. Each pixel or cell is somehow cyan, yellow, magenta and Black/white, but there is no clear explanation anywhere.

All current decent LCD / OLED/LED do about 16 Million shades/hues, HDR even more.

The mono eink has Black, White and 14 greys. Page turn speed is maybe slightly better than manually turning a paper page.

The mono is perfectly fine for reading novels as eBooks. Colour of either kind eink is not.

There was Mirasol, which is fast and coloured. Qualcomm own it. The exact reasons for its demise over 10 years ago is unclear, One model of ereader was made and sold under two Chinese brands.

I'd never buy a colour eink unless it was some new better CYMK layer technolgy not yet even invented that didn't need extra lighting.

Hmmm... black magic? Enough images of the ACeP cups around.

[Quoth]

That doesn't actually explain how it works.

It's totally obvious that each pixel rearranges cyan, magenta, yellow particles. Nothing in the animation or the website explain how this is achieved.

There are explanations I've seen basically boil down to the different coloured particles carrying different charges and external electrical fields which are used to manipulate the positioning of the particles. Not nearly as fast or easy as manipulating the black/white particles and at one point, I simply jotted down "and magic happens". Almost as much fun as learning about constellations in analog modems back when they were moving towards v.34.

Ah, but originally I was a Communications Engineer, so I had to learn maths to do with QAM. Thus given time and money I could make a modem, or Digital TV transmitter or receiver (for s, t or c).
An LCD panel or OLED panel is easier in terms of theory. LCD needs very flat glass, thin tin plating, a funky organic liquid, polariser and spacing so accurate that they developed special glass balls to go in the "glue" on the panel edges. OLED aren't real LEDs, but screenprinted or inkjet sprayed organic* electroluminescent chemicals with phosphor coating. Harder. Real LED panels are simplest if you use RGB 4 pin LEDs and make it the size of a billboard. Sony had a real LED monitor about $10,000 which makes OLED look poor.

I don't exactly know enough about Mirasol, but would seem to be amenable to the technique of a DLP chip (nano mirrors) if you wanted a projector. DLP needs a fabrication lab. I did some student experience in one, once. We have some near here, Analog Devices, where I have two relatives working. Though real Engineers and there years, they are not allowed into Fab.

If the internal number of the new Kobo device is correct, then I would say the new Kobo will be a Kobo Elipsa 2. The Elipsa is called N604 and for the new model it’s N605. That’s more than close.

[talaivan]

If the N605 is an Elipsa with 300 pixels per sq inch, I'll order it the moment it appears. I am hoping that the screen will be like the Sage's. The Amazon Scribe, which I bought (will probably return it) has some very serious shortcomings compared to the Kobo devices: it's too dim in dark mode, its margins are too large, its line spacing doesn't work for me, and its software is terrible. (I could go on about how it manages pdf's, makes you upload everything to the Kindle site, etc.) I need a large ereader like the Elipsa because my eyes are not very good.

[ps67]

If I remember correctly Amazon has a one year exclusivity on the 10.2" 300 DPI screen so we will have to wait until December to see a possible Kobo with similar characteristics.

[Sonnenfee]

Only a thought but a secret wish, a dream also: Maybe the new Kobo Elipsa come up with a 10.3" Mobius display and 300 dpi. That would be new and pretty cool
Add to that the ability to use KOReader on the new Elipsa ... and I'd probably sell my Kindle Scribe.

I really love my Scribe cause of the material he is made of and other things. The above mentioned dream would made me

[talaivan]

I find the Scribe harder to hold and noticeably heavier than the Elipsa. The back of the Scribe is smooth and slippery, while that of the Elipsa is not. The Scribe is only slightly heavier, but it does make a difference (for me, at least). The Elipsa is just more comfortable to hold while reading.
