Happy to answer any questions you have. Long time lurker, so this is pretty cool to finally take part :)
I made this because I wanted the eye-strain free and minimalist qualities of my kindle/Eink applied to so much more of what I do on a computer.
Lack of speed and ghosting felt like it made traditional Eink impossible to do most computing tasks. So we focused on making the most Paperlike epaper display that has no ghosting and high refresh rate - 60 to 120fps. We started working on this in 2018.
We developed our own custom epaper display tech we call LivePaper. We focused on solving the tradeoffs RLCDs traditionally have - around reflectance %, metallic-look / not Paperlike enough, viewing angle, white state, rainbow mura, parallax, resolution, size, lack of quality backlight, etc.
First proof of concept in late 2021, and then it took us 2.5 years to get it into production.
And we built a whole android tablet around it.
It’s essentially our attempt at making a remarkable tablet on steroids / kindle on steroids. Definitely some trade offs, but on the whole we think it’s worth it. (& on twitter a bunch of early customers seem to think so too)
Note: it’s 60fps epaper, not off the shelf Eink. We spent years developing what we think is the best epaper display in the world and it’s exclusively manufactured by our display factory in Japan.
There’s still many cases where traditional Eink is going to be better (bistability, viewing angle, white state color, etc), but we feel for more general purpose computers you can code on and do google docs on and do fast multitouch amongst a thousand other things, the speed and lack of ghosting totally makes it worth it.
Think of it as a Godzilla sized pebble watch with a decade of improvement
Or think of it as a gameboy advanced, advanced
You can get to a basic level of compliance fairly easily with state- and customer-based rates in select circumstances. But unless you dig deep, you will get things wrong, and you will only know about it when you get a potentially expensive audit years later.
