Hi Magnus,

I am really glad to hear about such project.

This idea would strongly interest a minority of people who suffer dramatically from the blue peak of white leds



This peak causes several indispositions, such as difficulty of concentration and insomnia.

Although as i said this problem strongly affects only a minority of people, it is likely that most other people have effects such as bad sleeping and disrupted daily activities without recognizing or even accepting it.

In fact unfortunately there is strong resistance to accept that white leds are bad for health because the majority of people apparently sleep well after using a laptop and do not even believe the remaining people when they assert it. However a massive number of scientific studies now are emerging fast.

Using Kindle as a secondary monitor works, however it is an unsatisfactory and incomplete solution. The main issue is NOT the whole screen refresh time as many people superficially assert. This because most users desperately require a secondary monitor of course not for playing video games, but for using much more basic productive software like word, excel, and eventually for browsing the Internet.

In my opinion the main issue is then JUST the cursor pointer reactivity.

I believe the solution to this issue is not really technological, but constructive and implementative:

1) having a refresh of only the portion involved by the cursor pointer

2) having a touch screen that is properly connected with the OS in order to allow most interactive operations like
- changing the position of the cursor pointer
- sliding and moving windows and lists

3) having a simple color schema in the OS (without useless frills like transparencies, shadows and so on) to allow easy usage of productive applications

4) good adaptation of the OS to the exact screen resolution of the e-ink

5) easy operations for connecting the secondary monitor and having the color LCD switched off immediately, without having to work with it for even few minutes before switching to the e-ink monitor.

PS: I would be pleased if you get connected with me also through Linkedin (https://www.linkedin.com/in/novation).

Hi edddh,

Wow that was a wonderful and insightful reply to my question, thanks a lot!

I'd love to see the references for the research you are mentioning, it seems really interesting and relevant.

I would also ask if you could share how you would use such a monitor? For work? Any thoughts on screen set-up? (Next to main screen, number of screens, etc.) As to understand your solution need in more detail..

Your comments on implementation trade-offs and workarounds are duly noted and I agree that many of the "technological" downsides can be offset.

I hope it's OK we keep it in this thread as the topic still is e-ink monitor related.


Thanks,
- Magnus

I am glad to see that an e-ink screen monitor is being developed and I would be very interested in being among the first to buy it, or even in using a prototype for testing/feedback.

I use the computer a lot with an LCD screen and several months ago I was looking for a newer monitor that would be easier on the eyes. After much research I selected a good LED screen that does not have the rapid flickering (PWM) and can be dimmed right down (I find many monitors too bright even on the lowest brightness setting). However I found that I was significantly more fatigued with the new screen. As edddh explained it is very likely to be the blue light issue. I've had to return the LED screen and go back to the old LCD, choosing "the lesser of two evils".

Aside from gaming and watching video, a significant part of my computer use is e-mail, web browsing, reading and writing. I would love to have an e-ink display that I can use for these purposes and have an easy way of switching to LCD for gaming/video. Perhaps a keyboard shortcut that can disable one screen and enable another. Or potentially having a displayport IN and OUT on the e-ink display with a switch button at the front. Pressing this button could power off the e-ink and redirect the signal to the OUT port, effectively changing the monitor on the same cable and forcing the OS to quickly reconfigure from one display to another.

I imagine that I would use both screens fairly equally, perhaps the e-ink even a bit more than LCD. I do not have severe symptoms with the LCD screen but I am very keen to have something that is easier on the eyes. For users like me, fast and easy switching between two screens would be an important feature.

Another suggestion is to ensure that this monitor does not generate electro-pollution to also make it the ultimate choice for electro-hypersensitive people. There are four main types of electro-pollution:
- Electromagnetic Fields (EMF)
- Electric Fields (ELF)
- Radiofrequency Radiation (RFR)
- "Dirty Electricity"
The main concern in this case would be the power supply used in the monitor. I'd be happy to explain how to test for all of these things.

While I understand that you really love to discuss this matter and while I consider this matter important, I like to ask you to stop hijacking this thread and open a new discussion instead. Also, I don't see how this would be Kindle specific, so this whole subforum might not be the place. You can then edit your posts to include a link to where you continue the discussion. Thank you!

hawhill, you're right, thank you for a fair feedback. I will start a new thread specifically on this in the coming days. Will post a link so people can continue the discussion there.

Sorry for the noise on your thread, and best of luck going forward.

- Magnus
