The TCL 40 NXTPAPER and the TCL 40 NXTPAPER 5G become the world’s first and only smartphone devices to offer a revolutionary full color paper-like visual experience.
Don’t know but I always liked them as an all rounder device. I think they are still using a last gen colour tech, but there are dual screen phones with lcd on one side and epaper on the other that are a nifty middle ground.
I don’t think colour eink is quite there though. The kaleido tech has enough speed to be usable, but poor colour and much greyer whites than carta greyscale due to the colour being a translucent pigment layer over the top of a greyscale screen. Eink gallery could be used but currently is much slower to do a full colour draw, too slow for a phone or tablet. Eink spectra 6 looks incredible but is also too slow for anything but signage.
There was one group showing off a prototype transparent OLED layer over a greyscale eink backing which sounds like the best of all worlds, so we will see what that amounts to.
Perhaps the perfect device would be more like a folding phone, with a nice modern oled on the front but a flexible greyscale eink inside. The flexible eink already exists its just not capable of a tight enough bend to work in something the size of a galaxy fold.
Hisense was going into the right direction with their A5 pro cc eink smartphones. Did they go any further ?
