I don't see anything related to reflectivity vs. backlight illumination. Most of the discussion is around the wavelength of light (blue) and its effects.
does light have any other intrinsic properties besides spectrum/wavelengths and intensity (EDIT: properties that vary based on the light source alone)? It doesn't matter if it came from a backlight or reflection, the electromagnetic waves are still electromagnetic waves. If the color spectrum is unpleasant, it's possible to use Night Shift or other features to shift the spectrum. If the intensity is unpleasant, just turn down the brightness.
The problem is LCDs have much worse objective performance as the backlight diminishes. E-Ink has tragically bad contrast of 15:1, but it maintains that contrast ratio in low lighting conditions. LCD panels rely on high brightness for their contrast. At very low brightness, even the best LCD display has poor contrast.
OLED displays have a different problem; they have so much noise at low brightness that the image falls apart. Still, I think a monochrome OLED display is what the person who wrote this article actually wants. It would have better performance in every respect to E-Ink, and it doesn't sound like their application requires E-Ink's low power.

I have used both LCD and OLED smartphone displays at incredibly low brightness in pitch black rooms for a long time, and I have to completely disagree.
On the other hand, E-Ink is amazing in sunlight, where smartphone displays can't get sufficiently bright.

Which smartphone displays can you set to 'incredibly low brightness'? all iPhones and Androids I've used are like bright flashlights when the lights are switched off.
It's all relative. I don't own a single flashlight that can be set dimmer (or anywhere close to as dim) as my iPhone XS Max is at minimum brightness on a white page. If the XS Max is showing mostly-dark content, the amount of light emitted is really tiny at minimum brightness because of that OLED display.
On the various Android devices I've owned, I've used a useful app called Screen Filter that adds a translucent layer on top of all apps to dim the screen beyond the artificial manufacturer-imposed minimum brightness, which worked especially well on OLED Android phones, but also LCDs worked fine too.

Presumably, all or most Xiaomi phones. I've never used one for long, but the lowest backlight level in those I tested (Redmi Note 2, Mi A1, RN5) was comparable to the level 2 or 3 of the Kindle Paperwhite frontlight. (level 1 is a failsafe option since the Paperwhite has no physical buttons, it's not meant for reading, being too dark even for a pitch black room)
That said, I don't think reading in poor lighting conditions is a good idea for your eyes, no matter the technology.

You can use an app to reduce the brightness further. I've been using Twilight on Android, and it does indeed get much dimmer. You will certainly lose some image quality/performance, but it's very nice for viewing in a dark room.
This is actually a reply to @Romed:

My understanding too is that OLEDs can have "true black" pixels that emit no light at all. For "dark mode" style screens, this is a huge benefit, because the majority of the screen may simply be turned off. Conventional LCD screens still send current to each pixel, but the "black" is simply tuned to a dark frequency, rather than being altogether off.

Yes, an unpowered LED emits no light. But an OLED that's barely on, for example at uniform 1% grey looks like crap because of the noise. People describe this as a "texture" or "banding". It's the consequence of trying to drive millions of individual semiconductor devices to the same emissive power. At higher brightness you can't notice the noise.
Lcd screens are transparent and selectively block the light from a backlight. They can’t show full black because they can’t completely block the backlight.
Yes, I know what electromagnetic waves are. I found your response very off-putting.
The question is whether the intensity is discussed in the link. My point was that the discussion is more to do with the frequency of light than with intensity.

Sure, think of things like polarizing filters, lasers, etc.
Sure, think of things like polarizing filters, lasers, etc.
Lasers are just a method of creating light of a single wavelength. The light itself from the laser is still defined by its wavelength and intensity.
Polarization is just related to the orientation of the electromagnetic waves, and it is a property I didn't mention, you're correct. I don't think it really matters here, though. It's kind of like which direction you shine a light, except whether the waves are all oriented the same way or not. I would almost argue that it's an extrinsic property since uniform polarization is almost exclusively the realm of external things like filters, not the light source itself.
Your "etc." is a little vague.

I really don't understand what your point really has to do with the original discussion.
Ok, light can be described by its intensity and wavelength. So what? Can you tie this to the original parent post?
You can break it down further - intensity is just the "number" of packets (photons). So, really, light is just frequency and travels at max speed (C) because photons are massless.
Where are we going with this discussion?
Edit: I am not able to respond to you below so I am responding here. You're right on this one - it doesn't matter what the originating source is, light is light whether it is reflected or emitted.

The argument is that since the light is the same, it can't have different effects. Reflected light cannot be inherently healthier than light from an LCD.
You were suggesting light doesn't have any other 'intrinsic properties' and that's not the case - phase (a laser is not just a monochromatic light source) and polarization come to mind. Whatever it is you're trying to argue, 'light is just wavelength and intensity' is not a sensible starting point.
Also, if we go a little deeper, then intensity is really not intrinsic property of photons themselves. Photons radiate through space and are carriers of electromagnetic force. They have momentum but no mass. Its energy and momentum is a function of frequency (or wavelength). Furthermore, they also have spin angular momentum which is truly intrinsic as it does not depend on frequency.
So, the saying that light is just "intensity and frequency" is naive and flat-out incorrect.

It isn't possible to make light that is faster or slower than other light, so does it matter that some other property is derived from this constant* ? A property derived from one variable and a constant property is perfectly logical to refer to as intrinsic, since it's always exactly linked to one intrinsic property. Splitting hairs there doesn't make sense.
Which things can a light source vary, besides wavelength and intensity? It's easy to define intensity in this context as the photons being emitted per period of time. This isn't like trying to define the intensity of sound as an intrinsic property, when it really depends on a number of actually intrinsic variables.
*within a given medium, which is external to the light... which means it won't change based on reflected vs LCD.

Is it not sensible, though? People are trying to argue that light from a backlight is inherently more dangerous than reflected light. The easiest way to dispel this notion is to establish that the light from a backlight is just light like any other, which it is. At most, it varies in spectrum and intensity. Polarization is affected by filters outside of the light source. The phase that's hitting your retina varies entirely based on irrelevant things like when the light source was turned on and how far away it is.
Starting by pointing out that intensity and wavelength are the only intrinsic properties is a great starting place.
You still haven't pointed out any additional properties that have any bearing on how your retina is affected. I was wrong the say that there were no other properties, since we can endlessly discuss the quantum nature of light or how it experiences no flow of time since it travels at the speed of light or all sorts of other properties...
but none of these things change based on the light source. Light is light, except for the intensity and wavelength. Unless we're willing to consider things which could affect reflected light just as much as they could affect emitted light, since they're the same thing. Light.

I'm not sure why you're so set on this obviously inaccurate thing and are now moving the goalposts to stuff about retinas and what the meaning of 'intrinsic' is. All I'm saying is both light and especially the perception of it are fairly complicated. You can just read up on it like everyone else instead of building a weird messageboard logic hill fort.

Yet you fail to point out the inaccuracies... I'm not moving the goal posts, I'm just clarifying where they were to begin with. You pushed them as far as you could within the wording of my original message, instead of taking the "strongest plausible interpretation" of my original message.

Light from lasers is also phase coherent. This is in sharp contrast to LED, incandescent etc.
Yea I remember that discussion. I'm not sure if I'm entirely convinced, but there are so many studies in progress looking at this that I decided to try running Redshift on my desktop again.
I will say, it does seem to make it easier to fall asleep at night.

The mammalian visual system has been the predominant model system used in developmental neurobiology research for the past fiftyish years. It's generally known at this point that visual circuits pattern themselves according to input, and that visual systems fed from a constrained input domain lose the ability to meaningfully represent real-world input. We also know that computer displays show a very restricted subset of perceptual info, and also don't relate to other sensory modalities (like proprioception of head/eye movements to look at peripheral objects) which are important for maintaining an integrated environmental map. So, it's more reasonable to assume that looking at monitors is harmful than helpful, especially at a young age (or following a stroke, taking certain HDAC6 inhibitors or other things that increase "neural plasticity"). The common knowledge of developmental neurobiology has advanced to the point where the claim "closer to natural ISN'T better for normal development" is one which requires proof.
Now, does this have any meaningful bearing on e-ink displays? The contrast ratio is closer to stuff you get in the natural world, but apart from that it's still a monitor.

Everything you said sounds really impressive, but
>visual systems fed from a constrained input domain lose the ability to meaningfully represent real-world input.
Seems to imply that looking at a computer monitor for too much of your life means you won't be able to see the real world, or not "see it right", whatever that means.
The only example of that I've seen is some people (kids, presumably) commenting on the Nvidia RTX demo videos that the non-raytraced versions, which lack real world lighting dynamics, look "better" than the raytraced ones, which were, to me at least, obviously closer to physically realistic, representative images. Now, whether they were saying that because their eyes have literally programmed themselves for cheaply rendered video game worlds, or because they didn't want to face spending the asking price of the RTX hardware, is up to the reader.

To add an anecdote from my adolescence: When I was 12-15 I spent pretty much all my time indoors, playing PC games or learning how to code. I realized I hadn't visited the river I was living basically next to for atleast two years when I had to pick something up at a booth next to it. I realized there that I found the water in Star Wars Galaxies much more "realistic" than the actual river flowing by. This freaked me out so much that I took a week off of gaming and went to take walks for a week.

I need to wear glasses with my retina display, but not with my e-ink reader. The eyes are definitely doing more work when looking at a backlit display for whatever reason.
Same distance, same text size, and same font?
also, same color scheme? I've seen some studies that show it's harder for people with certain vision issues to focus on text that's white text on a black background than it is for them to focus on black text on a white background, so.. if they're trying to read on a dark theme on their phone, that could be noticeably different from using their E-Ink screen, which is almost certainly using a light theme.
That would definitely be a good experiment to try. I would have to try a light black on light grey to match the kindle.
You get a LOT more light from a backlight than from reflection, at least in indoor conditions.
I can turn my monitor down so it's dimmer than a sheet of white paper on my desk. If I aim a desk lamp directly at the paper I can make it brighter than the monitor on full brightness. There's no standard brightness for monitor or paper.
What you're missing is that your eyes adjust the amount of light they let in and their sensitivity relative to ambient light, which can often result in a monitor having "inappropriate" brightness levels relative to that level. Nobody on the planet spends all day constantly adjusting their monitors' brightness and contrast levels, even assuming that it was possible to reach the appropriate levels in all ambient lighting conditions within the range of those controls (hint: it's not).
On the other hand, passive displays (books, e-ink) by their nature inherently match ambient lighting conditions, because they simply reflect ambient light. This is the equivalent of a monitor with a much wider range of contrast and brightness levels equipped with an automatic adaptive adjustment with sub-nanosecond response times, something that simply does not exist with present technology.
So yes, in theory a monitor could potentially match a passive display in terms of reducing eye strain and tiredness but in practice it is beyond the state of the art for now.

But can you actually READ your monitor when it’s dimmer than a sheet of paper in ambient light?
That's just a function of monitor brightness, it has no connection to whether the light was reflected or not.
If a monitor has bad contrast and you turn up the brightness, that's not the fault of the light source. That monitor still won't even come close to the amount of blue light that a blue sky emits, even at maximum brightness.
Personally, I think all monitors made in the last 10 years should be as legible at low brightness as a piece of paper is in an equally poorly lit room.

I would LOVE if E-Ink monitors became a thing. Spending all day indoors sucks. I'd love to be able to work outside in the sun for an hour or two.
Lenovo has released a Yoga convertible with an E-ink display.

Tried it this summer with 13'' Onyx Boox 2 as hdmi display and standalone. Both worked as expected, but somehow getting things done didn't really work well.
Interesting. Nice to know someone has used the 13" Onyx outside for work.
Curious - why didn't it work for you?

Not onyx fault: It was just too hot;)
Display is perfect in sun, but contrast not optimal in shade, so I couldn't escape the burn. Next time I try a 20m hdmi cable with normal display set to max in the shade.

I work outdoors every day when it’s warm enough, from a hammock. I use a 13” MBP. As long as you’re in the shade it’s great.
Polarized sunglasses help as well, and I have a color scheme for my terminal that’s dark-on-light that I switch to when it’s bright.

Yea I work outside in the shade as well sometimes. It works pretty well with a bright monitor, but you still have to be in the shade. I'd like to be able to soak up a little sun, while working.
I wish Sharp Memory LCDs[1] were made in 20"+ format. They're a hybrid between LCDs and E-paper displays with extremely fast refresh rates and the contrast is almost as good as ePaper displays.
I think monochrome displays would be fantastic for distraction-free coding or reading.
What's interesting is that you just need to toggle VCOM signal either through software or external source every 1-2 seconds for about 10ms. Therefore, you can keep the content on the display's memory for years on a coin cell battery.

Fascinating stuff. I wish this technology was available for computer monitor usage. I'd love to try it out.
Tangentially, the article shows video playing through eInk, and its choppy yet paper-like effect really reminds me of the animation style of the 1980s music video "Take On Me" by the band a-ha:
https://www.youtube.com/watch?v=djV11Xbc914
I'm not sure if I'd be able to use one of these monitors without constantly thinking of that video.

I'd pay a lot of money for a decent E Ink monitor. I don't need color or high refresh rate. I do need it to "just work", be reliable and relatively big.
The second step would be software support so that I could leave images on the screen when the computer is off.
Stuff mentioned in the article is interesting, but it sounds like the quality is quite bad for all 3.

There's been recent mention of the... Onyx Boox Max2, as Google refreshes my memory.
It can be used as a display via a simple HDMI connection.
I read a few articles, and I'd like to try one, but I haven't convinced myself to put down $800 .
Here's a googled link that my browser history says I've visited before:
https://goodereader.com/blog/electronic-readers/onyx-boox-ma...
P.S. As I asked at the time, does anyone know the/a source for the panel? Although I guess the custom firmware and buttoned down access to same, may make getting a raw panel a non-starter.
P.P.S. Duh. OP article mentions it. Anyway... still wondering where the panel comes from.

Thank you. At a first glance, that is an interesting/intriguing site.
Note that it's another $500 for the controller module they recommend. (I know, I was asking after the Max2's raw panel. But in considering making one of the ones on this site work.)
There's also a listing for a 31.2" panel capable of 4096 colors (per the description). $2300.

I have the MaxCarta and Max2. I use the older model using network connectivity, and the Max2 using HDMI. It is really a decent experience... just the refresh rate is slow. I use it for writing and reading large documents. And as concluded, since it is an Android device, it is multifunctional.
It also shows that any decent Android tablet should be able to act as a portable screen as Onyx does. It would make Android tablets a whole lot more practical, without the trouble of using WiDi or Miracast
Note: the Max2 can also be used as a Wacom tablet with some software, which makes it double duty and outperforming the Wacom Bamboo Slate I have. (They share the same pens!!!)

It's always going to be dodgy until the graphical OS you're running is aware of what eInk is, and adapts the UI toolkit and general rendering to play to eInk's strengths.
This might be one of those situations where things have to move forward imperfectly. First some people get eInk monitors, then OS developers see that there are at least some real users and some concrete reason to believe there's a payoff in supporting them.
Then decent software support will encourage more people to get eInk monitors, and that will encourage OS developers to turn decent software support into good software support.
A similar thing happened with SSDs. At first operating systems weren't TRIM-aware, but people used SSDs anyway. IIRC, first device drivers got support to send the TRIM command, then later filesystems got the ability to send the TRIM command automatically, then flash-oriented filesystems were built and went into wide(r) use.

My worry is that E-Ink Monitors will never reach the "minimum quality" point at which they are adopted by a sufficient number of people to get the ball rolling.
I don't suffer from any medical reason to use one, but, I would absolutely purchase one this second (any pay a lot for it) if it worked well. Unfortunately, what I've seen so far from the Dasung and the Onyx, isn't worth $800. I just hope these companies have enough runway to continue improving the product such that early adopters like myself, will jump in.

What will cause it to be worth $800?
Maybe just setting Windows into one of it’s High Contrast Settings would help[0]. I’m sure MacOS offers a similar feature.

I feel like I've been looking into this every 6 months since the mid 2000's and there's still little progress. I would be thrilled if someone made a 20" - 27"screen with a simple HDMI connection; I don't care about the refresh rate.

I posted to ask last year asking why mid size and larger E-ink devices were so expensive relative to 6inch readers.

The main reason is production costs. A single 13" screen is being sold to manufacturers for over 350.
I would give up my code colouring for an e-ink monitor for coding. Such a delightful possible future here.
I've been using these schemes in my terminal and editor for years now:
base16-grayscale-dark
base16-grayscale-light
A 40 Hz model is already down to $1000. We may be on the cusp of some kind of sea change here. How insanely light could an E-Ink flatscreen monitor get? You don't need a backlight, so the power requirements would be much smaller and that would be a huge advantage to making something light. I could imagine an updated version of a "Sunflower" iMac built using one. MacOS resembling a magazine seems to be what Steve Jobs envisioned and what Apple is aiming for right now. Could they be made in such a way as to resemble good sheet material for acoustic exciters?

Is that project still alive? I don't see any activity in the past few months.
Yes, as far as I know Juul is still working on it. It's pretty much just one guy and life does get in the way of open source projects.
And with Exeger e-ink devices will have eternal life :)

These would make a great wristwatch, so you can get perpetual display of time with virtually zero power, and should get long battery life.
I believe Nokia/Withings offers a fitness tracker with an eink display with a watchface.
That is correct. Nokia/Withings Steel HR on my hand contains a small, surprisingly fast e-ink display (although low res).
They also have small, barely noticeable LED lights lighting the screen to be visible during night. Much more pleasant way of checking the time during the night than looking at a phone. And its battery lasts 2-3 weeks and charges in two hours.
The screen isn't always on though, and only activates on a click from the side.

I have a max 2 since almost it was released and even if it can work as a display, it isn't ideal
ghosting and a lower resolution needed to have a better refresh rate, kills a lot of the charm.
imho, they can work but on a pretty niche way, but I wouldn't buy one just to use it as a display.

> E-Ink Monitors: Ready for Prime Time?
13.3" at $899. I guess that answers the question.

If the maximum size is 13.3" as shown here, then no... they are not ready for prime time. That is big for a tablet or e-reader, but small for a laptop, and tiny for something called a monitor (outside of a colo).
they are 4:3 ratio, so for a laptop is more than enough
Well I haven't ever seen a laptop with 4:3 (1024x768?) although I loved my ancient 20" 1280x1024 5:4 monitor and there are lots of smaller 3:2 surface-like laptops. The 13.3" (and the tiny 12) still accounts for only 20% of the 2017 market, with 14.1-15.6 (and even larger) accounting for the remaining 30+50=80%.
This was about the market for Monitors though... not just displays in general so this e-ink display just doesn't cover a significant portion of the market outside of tablets or very small laptops. Typical monitor sizes are 19-34", with the smaller "totable" 15.6-17" sizes accounting for <20% of the market. 13-14" aren't even listed as monitor sizes by the marketing groups like IHS or Display Search.

this ereaders doesn't have 1024 or 1280, the eink resolution is 2200x1650
Yes, I read the article. However, I have never seen a laptop use such a aspect ratio even in the olden days, and I'm not sure manufacturers would choose to now, because... These are high resolution low contrast reflective screens limited to 13" which do not hit the current market diaginal/area expectations for mainstream laptops, much less desktop monitors.
They are good for low power daylight operation and I'm sure there is a small market for people who don't like backlights and emissive displays. I like my kindle for books, but I also don't mind the backlight for indoor use. As desktop monitors they have missed everything but the smallest niche.
Good luck if you really want to use one regularly as the writer says,"Based on my research, particularly great e-ink monitor comparisons, these devices are not ready for professional, daily use. They are laggy, have staining/ghosting problems, and perhaps worst, are quite unreliable. It seems that the failure rate on both of these devices is quite high and user happiness is quite low. If e-ink is your only option (because of health reasons) then these might be a savior, but short of that it seems like your best best is to wait for future development in the space."

Seems like the Lenovo Yoga Book C930 would do the trick.
Source? Light is still hitting your retinas, whether it comes from reflection or from a backlight.
I really enjoy E-Ink displays, but not because of perceived health benefits from reflected light. I enjoy how readable they are under sunlight, how they consume zero energy to show a static image, and how this enables them to always show content even if the device has no power.
It's simply not necessary to use unsourced health claims to justify a great technology like E-Ink.
