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.

But can you actually READ your monitor when it’s dimmer than a sheet of paper in ambient light?

Not much. I can't read those trendy gray on white web sites too.

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…

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.

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…

https://news.ycombinator.com/item?id=17724995 Was a good thread

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.

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.

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.

This is actually a reply to @Romed: 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. My understanding too is that OLEDs can have…

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.

It's ironic that this advice is written on a website with an 0xFFFFFF brilliant white background.

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 kn…

I searched for a teardown, but only found one of the Dasung Paperlike Pro https://kevzettler.com/2018/02/11/dasung-paperlike-pro-teard... , but which helpfully links to a source for the panel. The biggest display they have seems to be a 42" monochrome display for $2000 https://shopkits.eink.com/product-category/e-ink-display-mod...

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.

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.

That's an additional advantage. :)

Outstanding for sure
