The only currently similar available product is the Dasung Paperlike 103 but they warn that the it's not safe to expose it to the UV in direct sunlight. You'd need to jury-rig a UV filter over it I'd think.
E-Ink's own site doesn't list any display modules that is larger than 13 inches that also has touch ( https://www.eink.com/product/epaper?search[]=16 ) so it's unlikely there is such a thing. Neither of the e-ink monitor makers, Dasung and Onyx Boox, list touch capability on their 25.3 inch monitors either.
I'm wanting to build a solar-powered e-ink laptop - so you can write / code in the sun. Mint Debian under the hood.
Open to ideas - trying to keep everything open-source architecture.
I have an e-ink phone from Bigme, and their refresh rates are pretty good to, but their only >20 inch display doesn't have touch support: https://www.aliexpress.us/item/3256807215559517.html
