The Wiki info was interesting! So it is not a colour e-ink display with Toppan colour filter as some of us thought. But it is a competing technology, which is more like a static LCD display:
“display composed of three cholesteric liquid crystal films (red, green, blue) attached to one another”

Some example products that have used this technology are: Panasonic Sigma ebook, Kolin/Argosy i-library..
