You complain of eyestrain issues from low DPI, and many others have eyestrain issues from backlighting on LCD and AMOLED displays. Different strokes for different folks.

Hi,
I prefer read on a e-ink screen, but a big advantage of e-ink reader is the battery life. I use my device like a book and I don't worry about the charge of the battery. When you read a paper book, do you think to take with you a battery ?

I found I could not use tablets with less than around 260 dpi. I literally saw yellow halos around all text! Gave me headaches. I remember wanting a tablet so badly in 2012, bought hubby a Nexus 7 (2012), but I just couldn't deal with it. Had to wait a year for the higher resolution Nexus 7 (2013) to come out.

Everyone's different, that's for sure! I definitely like the higher dpi on my ereaders as well, though I was able to actually use the original Nook and then Sony 950 without issues. Absolutely loving the Kobo Aura One display though!

Can remember people saying tablets and readers didn't need higher dpi back when, but I really like it! Gimme the pixels!

I'm not impressed with your lackluster reply, dude

LCD is so 90's... try at least amoled and good luck trying to read under the sun or with low battery after a day of drainage

The absolute number of DPI is not the correct number to use to determine readability.
The correct number is the viewing angle subtended by the pixel size.
That is determined by the combination of the pixel size (or DPI, aka density of pixel) and by the distance.

Another way to put it that I like is to ask: given a DPI at what distance it becomes a retina level?
And the answer is not "150" or "300" or any single DPI number, is the pair: DPI and distance.

You can use this retina calculator to do the math.

But given that we are talking about a 13.3" screen with 1600x1200 vs 2200x1650: the first 150 DPI and is retina at 58 cm (23") distance, while the second is 207 DPI and is retina at 43 cm (17").

So not perfect, but 43 cm for me is close to where I would place a screen of that size, while 58 cm is clearly a bit too far, hence I do appreciate the extra resolution.

Comparing this DPIs to your experience with tablets and phones is misleading unless you keep distance into account: the iPhone 7 is 4.7" and is 1344x750 and is retina at about 28 cm (11"), and nobody (or few) complain about its resolution, But for sure you don't consider reading an eReader 13.3" wide at the same distance at which you hold a smartphone.

I wonder if it its performace as an external monitor will be better than the paperlike

Why are these so expensive? Do e-ink screens really cost that much to produce?

It's not the cost of production so much as the fact that this is never going to be a mass-market product, and so a relatively small number of sales have to repay the development costs.

Makes sense. I am really wanting a large e-ink reader. Something in this size would be awesome. The only other option I can see getting is the Onyx Boox Max. Still pricey. Oh well...

I have a Voyage and a Paperwhite with a 300 ppi screen and and the older Paperwhite with the 212 ppi screen. I personally can't tell the difference. I'm told that some people can but I really doubt that would cause eye strain.

E Ink/Prime View Int. acquired most of their competition. E Ink is the only one who makes electronic paper displays. Monopoly is a bliss.

Or a small niche market that could not support multiple sources. Amazon purchased Liquavista from Samsung (originally owned by Phillips, sold to Samsung) and since then nothing has been heard about their technology. SiPix was acquired by E-ink Holdings. Another potential competitor in Bridgestone (yes, the tire company) simply ceased development on their version of e-paper. Xerox stopped work on their version of e-paper (Gyricon) due to cost issues. One surviving competitor is DisplayData though they appear to be solely concentrating on shelf labels at this time.

You might want to check the total for ereader sales from their peak in 2011 at 23.1 million units to 2016 where about 7.1 million units were sold. Not only a niche market but a shrinking niche.
