Aclaratory notes about e-ink

[jiyong]

As for your question about the screen, all eInk screens are made by precisely one company. In essence, if you have seen a 10.3 inch eInk display, you know exactly which one it uses.

Sorry to jump on this one, but I am one of the backers of the Reinkstone R1 and that one uses Display Electronic Slurry (DES) and is a different technology than current screens.

Correct me if I’m wrong here, DES screen resolution is:



1680*2232
But that screen has a color filter on top that is always there, which enables the color part, down the filter is still a 16 grayscale Eink.
Which leads me to believe that using color you have really that resolution/3

The Onyx Boox Nova 3 Color for example has a color resolution of 624×468, and can display black and white content at 1872×1404 with 300 PPI. One of the drawbacks of his CFA is that color cannot be turned off and on larger screens, the color gamut gets deluded, making everything everything a bit washed out.

I'm not sure what exactly you are trying to tell me, but just because they have similar resolutions, doesn't necessarily mean they are the same kind of display. DES is a different screen technology and not the same as Kaleido.

From your link:
"The DES display module adopts a new display structure which is completely different from the current micro-cup and micro-capsule structure. The structure forms a layer of cofferdam structure on the surface of the TFT by forming a cofferdam around the periphery of a single pixel electrode, and the bank covers the source and gate lines on the TFT. The patterned structure is characterized in that each pixel electrode is surrounded by a cofferdam, the microstructure is not visible on the front side, and the number of layers is reduced, thereby obtaining the higher definition and resolution display effect. In order to distinguish it from the traditional micro-cup and micro-capsule technology. Basically this tech uses 3 stages, ITO Glass, Plasma and a TFT. E INK uses TFT, adhesive, the EINK Panel, Color Filter Array, ITO film, adhesive and a protected layer. There is often an additional layer of glass, protecting everything."
