Again TCL misrepresenting their NXTPaper display. At least they've stopped actually calling it "full colour epaper" which was an outright lie and moved to "paper-like" which is wrong but legally they can get away with that.
These are IPS LCDs, with standard backlighting. they have a highly matte surface and a semi-reflective layer for improved daylight viewing. they are not E-ink or E-Paper or any of those fully reflective technologies.
Thanks for the clarification! I think there is still some merit to a more paperlike display, I wish Google kept Ambient EQ beyond the Pixel 4 because it's quite nice on iPhones
Hisense was going into the right direction with their A5 pro cc eink smartphones. Did they go any further ?
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.
They did not show any animations in the keynote, suggesting that it may have similar refresh rate issues to a standard color E-ink display.
The NXTpaper displays are standard LCDs with a highly matte coating and some processing and colour rendering modes to simulate paper, I think they have some transflexive film to make them more sunlight viewable, but still have a backlight.
They are not e-paper, or e-ink, nor are they a fully reflective display.
