E-paper and e-ink are synonyms (well, to be more precise, e-ink is a brand of e-paper, but those terms are being commonly used as synonymous). Not sure what you're referring to regarding transflective screens, as both the article and my comment refer to displays that only need power to update their content.
I also have a device with a transflective LCD, it's called Nokia N900 - it would be hard to mistake one display for another ;)
Pebble had branded its transflective LCD display as e-paper. So, it signifies transflective display commercially, unless owner of the trademark decides to do something else with it. (I'm not sure though the term was trademarked, but it had been used for transflective displays for a while).
While classic Pebble used TLCD, Pebble Time used actual e-paper. Also, note how this "trade names" section has no references, and includes an entry called "sunlight readable lcd". There are no trademarks involved there.
They absolutely are not. E-paper is a generic term for "screens that can be used like paper". E-ink is a specific technology.
If you see people saying a device uses an "e-paper display" it's because it's not e-ink, but often they want to make people think that it is (because e-ink is arguably the best kind of e-paper display).
Transflective LCD is an example of an e-paper display that is not e-ink.
> Electronic paper, also sometimes electronic ink, e-ink or electrophoretic display, are display devices that mimic the appearance of ordinary ink on paper.
> Many e-readers (...) utilize electronic paper for their displays in order to further resemble paper books; one such example is the Kindle series by Amazon.
Unless specifically noted otherwise, you can safely assume that anyone talking about "e-ink" or "e-paper" means the kind of display used in Kindle, Inkplate or the art frames this article is talking about. There were cases of RLCDs and TLCDs marketed as "e-paper" in the past, but those are rather exception than rule, riding on the popularity of the real thing. Nobody considers calculator or OLPC screens "e-paper".
It is not. It is a brand of electrophoretic display, which is a type of e-paper display.
> There are other brands that utilize the same technology.
There are not. Not any significant ones anyway.

No you can't. "E-ink" displays are definitely e-ink. But an "e-paper" display could be e-ink, transflective LCD, or anything else. There are real products that use transflective LCD and say they have "e-paper" displays. The Pebble watches are the obvious one (sadly discontinued).
There are tons of e-ink products that are described as having e-paper displays which probably contributes to the confusion, but the meaning is quite clear.
