    Perhaps. This seems to be a new form facor since wikipedia last surveyed the production line of eink corp.

    By the way, if anyone says they've got a Pearl or a Carta screen it means the screen came from e-ink corp. They do sell a cute round 1 inch one (or did in 2017 anyway) that could be a good drop in for a slightly modified lid back on a pyra.

    I'm pretty sure I found the screen they are using:

    Maybe this could be used on the Pyra phone? Something to set it apart a little bit? Maybe like mentioned before a drop in replacement, the board could work with either one. Without Android games I'd much rather have an e-ink screen.

    Or glass backs are a thing now, lets have this be the rear screen. . .

    One at a time for developers, yes. I wonder where the price breaks for volume start kicking in.

    Exactly my thoughts - though I have no idea what kind of adapter we would need let alone if it is MIPI to match the main or ---... Just a real interesting bit of kit at this point that happens to match the Pyra's resolution 1:1 and REAL close to the same size...

    Just be aware this doesn't come with a touchscreen. I'd not really considered it before, but presumably that's going to be the main mode of input on a pyraphone.

    What's the refresh rate?

    480ms according to the stats from the page linked above. If you need a refresh rate that equates to just over 2fps, although most of the time it'll be flashing black and white if you actually tried to run it like that to play a video or anything.

    Neither did the screen we are using for the Pyra. I would assume that a touchscreen layer could be added using the same methods?

    Hmmm, not so sure. E-ink displays use static electricity to attract the pigment balls to either side of the screen. Basically it's a segmented capacitive layer where charge dictates pigmentation. Maybe a resistive touchscreen could work, but I'd bet a capacitive one would interfere like mad with this.

    ...You do realize that neither the Pandora nor the Pyra were ever planned to use anything else than a resistive touchscreen?
