Thin-film-transistor liquid-crystal display

If you believe what Good e-Reader is saying (and I realize that some opinions on that source are negative), this wouldn't be a color version of electronic paper, such as used in products like Kindle and Kobo eReaders. It would instead be yet another backlit screen product.

Or, as does sometimes happen, am I totally missing it?

What also puzzled me is the article talks about using RGB colors, which I thought was what's used for transmitted light like our monitors, tablets, etc. but for reflective light, like print, I thought they'd use CMY (aka blue, red, yellow).

RGB is additive color, CMY is subtractive color. Color eink uses sub-pixels next to each other, so additive color is used.

c/p

" Flexible displays have been discussed for years, but product designers were unable to bring their visions to the market due to limitations in TFT manufacturing on non-glass substrates. After many years of R&D, E Ink has launched E Ink Mobius, the first plastic-based TFT product offered in mass production ... "

Lots of people would welcome a large 12" or more color e-ink device if it were competitively priced.
The problem there is what is 'competitively priced'? I bought a Surface primarily because I wanted a 12" screen to read comics. But I was able to justify the cost because the Surface was also able to replace my laptop.

I'd like a nice 12" color e-ink reader. But would I pay $1,200 for such a device that I at least would only use to read comics? Probably not.

In the 50s a lot of doctors didn't say that smoking is bad for your health. The damage, especially from the intensive blue light, will accumulate slowly.

I don’t see this as viable except for whatever the market is for reMarkable and Sony DTP devices (~$600). Marking up PDFs, with color business graphics.

Most schools are fibre connected and interschool sharing of learning and live video over the internet is common, as is distance learning over the internet for children living in remote locations.

Of course, this is all with LCD or OLED display devices, so according to you they are all damaging their eyes. That would be regarded as a wierd idea to everyone involved.
I am outdated. My wife just told me that children from 12 years old use computers in class. For me a mistake. Reading for hours on those screens is not good and tiresome sight but hey ...
