It is not dead. The gentleman in the video bought it on amazon, just search for "pixel qi amazon" on a search engine, and you will find it.
It seems that Pixel Qi displays are now made by a company named "Tripuso Display Solutions". They have a website, and it seems that they offer screens up to 19 inch on their home page. Would love to see a Pixel Qi review for a large screen (bigger than 10").

Not a proof. With "dead" Whopper very probably meant "out of R&D and production". We are informed (but thank you nonetheless for pointing that out, for the uninformed) that already produced PixelQI displays are still for sale.

Please provide some information about Tripuso actually producing the displays, and, especially, continuing R&D - instead of just acting as resellers and having inherited industrial properties.

Can someone explain to be what's the big deal with Pixel Qi screens?

They are reportedly, just Transflective Screens, which have been around since HP's iPAq Pocket PC from 20 years ago. These screens also work without backlight.

What are the differences? Pixel Qi vs Transflective Display

I have no idea who produce the displays they are selling, you should ask them directly. I am completely new to this.
All I see, is that we have here a reflective technology which seems great for monitors (great refresh rate, no lag, very cheap to produce), and we end up with very laggy and overpriced eink screens. It doesnt make sense from a user point of view...

It might make sense if e-Ink has significantly better readability compared to Pixel Qi

Pixel Qi Review – Pixel Qi Vs E Ink and LCD:
Quote:
"While Pixel Qi screens are no where close to E Ink screens like the Kindle 3 in terms of readability with the backlighting off, Pixel Qi screens are much more readable than traditional LCD screens outdoors and in bright light."

Mirasol's was a different color e-paper technology, also dead now.

Hopefully Clearink comes the very next year and stays for years to come through its improved versions, till some even better color e-paper.

The gentleman in the video, who is an IT engineer, doesn't seem disappointed at all with the Pixel Qi readability, so I am not really convinced by this statement.
Eink technology is great for an ereader or any static use case, but it is a bad technology for a monitor or a tablet as it has bad refresh rate and lag.
Moreover Pixel Qi technology was very cheap to produce and affordable to everyone, compared to eink overpriced licenses. That aspect is important too in my opinion.

You are right, Mirasol had nothing to do with Pixel Qi. Different technology. Thank you for pointing that out !
I have just corrected my initial post now.

I will be more clear: the idea seems to be that the PixelQi displays on sale are remainders. So it is not that they «are now made» but that they could be made by the firm that now owns the rights.

I do not recall any information about PixelQi technology being actively developed (nor of the production being still ongoing - which would not be sensible without R&D, at least since the only current format available is the one which fit the One Laptop per Child initiative), and I have been actively searching for news, like many here, many times, periodically, reading Mary Lou Jepsen's biographies, agiographies etc.

Have not you written «seems». The PixelQi, while many of us would have bought it, remains a compromise - just like all other technologies, but with degrees. Its final quality has not surpassed the threshold to get the interest from current players.

You «end up» with the sibling (from MIT like Jepsen) E-Ink on your own free initiative, not as a "certified solution" but as a patch to the limited market interest on natural-light friendly technologies: we have been reasonably and rightfully bending the comfort zone of E-Ink ("contemplation") to a dynamic usage which was beyond the direct focus of the engineers.

It was emotionally touching to skim through the comments:
Quote:
  • Normal screens are just not readable without improvising a dark room with hands or clothes. [Yep!]
  • Navigation on a motorcycle (road/bush/dirt) would be possible with transflective. [Been there]
  • Wouldn't some marketing "genius" figure out that mobile phones are crap in sunlight? Mobile implies...... drum roll ..... OUTDOORS!
  • my [...] is worthless in sunlight... which we have a lot of in [...]
  • Outside in the southwest, on a bright summer day, the ambient light can reach 80,000 to 100,000 Lux
  • The whole idea of [mobile] is for the freedom to be outdoors
