The Hisense A5 was unveiled last year with an e-Ink display. But that was a monocrhome screen, this year the company is showing off a new prototype phone with a color e-Ink phone at CES 2020.
Details are scarce at the moment, but the new display reportedly features improved contrast and refresh rates compared to the panel on the A5. That said, color e-Ink screens tend to have much slower refresh rates than the already slow monochrome screens, which isn’t an issue for an e-reader, but is really limiting when it comes to smartphone UI.
Anyway, color e-Ink panels are reportedly set to go into mass production in Q2 of this year. However, Hisense didn’t announce a time frame for the launch of this phone.
The reduced eyestrain and excellent legibility of e-Ink displays make them an interesting choice for phones. If Hisense has managed to crack the refresh rate problem, it could become a really interesting option.

VR was done before and failed. That doesn't preclude concepts from coming back and being successful when better technology becomes available.
Hasn't the whole E-Ink thing been done before and failed forget the OEM
