Here's their real website: http://www.dasung.com/english/ I cannot wait for the day when large e-ink displays are cheap, or as cheap as normal screens, and have faster refresh rates.

I just want an 8.5" x 11" version that is portable, runs Linux, and can open PDFs. For reading papers you wouldn't be able to beat it.

Apart from the "Runs Linux" you might be able to find a Kindle DX. And then you might be able to hack it to run Linux.

I bought one used in university and would use it for reading PDFs. Really slow refresh rate, but who cares if you're just reading big pages?

It's notre direct light - starring at the sun (extreme example) severly hurt your eyes while watching at shadows is not a problem.

That's because the sun is really bright. You might just as well just dim your screen. A bit like these sun solace sunglasses :)

it is NOT the same at all. There is a lot to this that you're obviously ignorant of. There is a big difference on your eyes, brain, and sleep cycles between transmitted light and reflected light even when your screen is set to a low brightness.

Sony makes one, https://www.sony.com/electronics/digital-paper-notepad for $700 but it's a product being sold to consumers, so tinkering with the underlying OS (reputed to be Linux, in the form of Android) isn't supported. (There are a number of other 8.5"x11" eink PDF readers out there.)

The Digital Paper Notepad is a discontinued product. What other 8.5"x11" eink readers are there?

Please don't spread disinformation. The new one was just released and is available for pre-order on Amazon. The refresh rate is supposed to be fast enough to watch videos and read books without lag. I have already pre-ordered one and can't wait to get it. It will be great for reading mathematics books in PDF form.

That is the old model. The new model was just released and is available for pre-order, shipping late June/ early July.

Here is the pre-order page on Amazon: http://amzn.to/2sg3Db6

At least explain "a lot" before calling me ignorant, I'm always curious about scientific explanations. (but don't bother now, I'm hereby out of this discussion)

For a non-PWMed high DPI monitor adjusted to match the e-ink's brightness and contrast, the only difference in the light hitting your eye is the spectrum and the polarization. It's not completely impossible for these to matter, because of interactions with optical imperfections of the eye, but I've never seen any evidence that it actually does matter.

What about blue light? I've been hearing about that being a problem lately.

If you wish to use an e-ink screen to avoid eyes strain, I've recently learned that a video projector does have the avantages of a classic monitor (colors, good refresh rate) without having to watch directly at the source of light, thus avoiding eyes fatigue. I consider it to be a better tradeoff than working with an annoying delay as if you were using a 10 years old computer.

A projector can be a good option. However be aware that people may also suffer from headache when using DLP projectors.

Blue light stimulates intrinsically photosensitive retinal ganglion cells, which influence sleep. Visually identical white lights can have different spectra and different effect on these cells. Eg. "warm white" made from RGB with the blue channel turned down, eg. as with f.lux, will probably stimulate those cells more than sharply long-pass filtered (eg. with a dichroic filter) broad spectrum light of the same color temperature.

These cells are also responsible for light aversion, at least in animal models, eg: https://www.ncbi.nlm.nih.gov/pubmed/23078956 , so it could theoretically make a difference to eye strain, especially at high brightness levels.

However, if you read the e-ink under fluorescent or LED based lighting it's probably going to have a similar peaked spectrum to the LCD screen and there will be no difference if the brightness and color temperature is the same.
