daniel_mate Then I am very confused as it says "3rd generation" everywhere and I have seen 3 diffrent resolutions listed that lend to that. The older ones had a symmetrical bezel and the "3" has a fatter bottom bezel. I have also seen articles talking about 3 different models over time so don't understand the naming conventions.
Anyone with a Dasung Paperlike 3 yet? Report?

I have a Yotaphone 2 and it's eink. I agree the tech is almost useless. It is only good if you aren't outside.
Speaking of e-ink, I came across another kind: https://www.iristechnologies.ca/Product/Product.php.

ryans I can't find anything but marketing speak on their site to see if this is just a rebranded Dasung or some new "E-paper" tech as they infer...but I suspect the former. It looks to me like it has the exact same bezel and button layout/markings as Dasung Paperlike Pro which is Dasung's last gen model. There are no tech specs listed to compare resolution etc.
They seem to be marketing it toward people who are light sensitive post concussion and acting like they "developed" some special technology that helps that, rather than actually selling what is just an existing E-ink monitor, something you can already get much, much cheaper. 2000 CAD to buy or 400 CAD a month to rent? Ridiculous. If it IS a Dasung rebranded, the equivalent Dasung model is half that price. They say "Patent Pending" but I can't see what they could be patenting other than their brand name perhaps.
I could however be entirely wrong and it's all some new tech and the similarities are coincidence. But if my suspicions are correct I REALLY hate this sort of "business" where people take an existing thing, mark the price up, and deceptively market it as unique. They add no value and just insert themselves for profit.

JTL If they have actually created a stand alone monitor like the Dasung then I wouldn't feel so critical, although I still wouldn't buy one at that price.
What really bothers me however is that their business APPEARS to be rebanding an existing product, marketing it to a vunlerable population as some special medical assist device, and making a hefty profit in the process. The 400cad per month rental fee is absolutely robbery imho. I guess there is always the chance they have done some amazing firmware work or something that is somehow relevant to head injuries and frequencies but there is certainly nothing on their site saying so...there is nothing but marketing speak and no technical info. In my view if you really care about post-concusion patients and the studies show E-Ink is better for them, then you will raise awareness about the Dasung instead of trying to take advantage of ignorance.

Agreed
Going to try and find an email for them to set the record straight.

JTL I thought Canadians were all super nice and decent...this seems like the kind of shady business some wunderkind in Silicon Valley would do.
I may be being too hard on them and there is something we just don't know that validates their costs. But I'd be surprised. Happy to be wrong and apologise for the assumptions if that's the case.
That resemblance though, looking at them side by side, hmm.

hpst I need to catch up with this thread, but have you considered posing your queries directly do DASUNG? I talked to them last April when I was thinking of purchasing one of their displays. My questions were mostly about the logistics of importing the product without paying 500 bucks of taxes, and little technical. They replied very promptly and they seemed to care about the customer. Being a small company trying to serve a niche market, they could be interested in hearing your/our doubts and reading thru this forum. I think there is a lot of material for someone who wants to develop a technology that does not strain eyes.

daniel_mate I think 3 = HD.
Pro is the old one.
I confirm. 3 = HD = third generation device; earlier version (2nd) = Pro.
The HD has a matte display, whereas the Pro has a clear lens screen (that is how the Dasung customer care called it, kinda glossy I guess) with the option of a protective film on top.
They also said a bit of dithering is noticeable, being caused by the dithering algorithm of the E-ink monitor itself.
Not sure how to take this, since I know nearly nothing about dithering nor I am an hardware person.

I have the latest model HD and I get eye ball pain and spasms in my head, headache after using the screen for 30 mins- 1h. Even going to cinema is much much nicer than this eink monitor Not sure how it is possible and why it happens. I use it with 1100*825 resulotion A61 mode. Anyone else get eye strain from Dasung or other eink products? What settings do you use? I was testing it with both 40 HZ and 80 HZ and haven't noticed any difference pain wise. Also as already mentioned the HD resolution is useless as it is impossible to read anything, it is too tiny.
Anyway the lag doesn't bother me at all, as I would only use it at home for chatting or quick lookup of some information.
randomboolean I have the latest model HD and I get eye ball pain and spasms in my head, headache after using the screen for 30 mins- 1h.
Seriously? That is very bad news, as I was strongly considering making a move and purchasing.
Can you rule out the issues are due to the device you plug in? Have you tried other devices? Thanks!
AGI I have tested with 2 HP laptops - one from 2014 and the other 2018 model. Both give the same results. I will be testing with older devices sometime later and will update you about the results.
I think it is important to note that I am also testing my new phone Hisense A2 pro, which also gives me some kind of tension in the head. I am not sure why, because the response rate seems the same as on my yotaphone 2 eink side, which is perfect. The only difference between yota and hisense is that hisense is built with glare screen and the yota - plastic. Yota looks like picture or caricature, toy phone (as many people said to me) and the hisense feels more like real phone - just black and white. And yeah, on yota I was using a lot of black backgrounds and hisense is mostly white everywhere.
I think the problem might not be the refresh rate or flickering, since I cannot read books anymore too. I think I might became intolerant to high contrast or bright white in general. OR maybe my eyes got weaker and I need vision therapy, thus I found one of the best oftalmologist in the country and will ask to do in depth testing of convergence, suppression and everything else mentioned on this forum. Also I ordered pack of IRLEN overlays, which should help if my problem is contrast. Will update on this too.
randomboolean Thanks on your feedback.
Is Hisense A2 pro an e-ink smartphone?
What are IRLEN overlays?
Thanks!
