An iPad-sized, Kindle-like reader would be a godsend.
These things do exist (Sony DPT, Onyx Boox, ReMarkable) - they're just more expensive than you'd expect them to be considering what they can do.

#32There is a need gap for 'Affordable E-Ink large external displays'[1].
Dasung, Onyx have been market leaders in this category and they are expensive. There are E-ink tablets from several other manufacturers as mentioned in other comments, but they rarely are external displays.
Then there are reliability issues with cheap DIY E-Ink displays, they don't last long and especially when displaying low refresh rate data like Weather, todo list; there will be ghosting issues quite soon.
I'm not exactly sure on whether manufacturing large E-ink external displays is just an unit-economics problem which will get resolved with improvement in technology or there is some underlying Intellectual Property issues from the likes of Amazon,Dasung,Onyx etc.

From previous discussions, I remember it being a company sitting on the tech.

#34Earlier quoted context omitted.
Was thinking something similar - rather than an old panel you could take a newer large high res panel, chosen carefully so it's easy to separate from the back-light. I wonder what it would look like with just paper behind it instead? (or a slightly more reflective white material). I wouldn't expect color to "transflect" very well, but it might work ok as a simple 1-bit screen, fully transmissible as possible reflecti…
This sounds pretty similar to the display on the Pebble Time. It was a color LCD, sometimes marketed as a low power LCD or reflective LCD. For the majority of the time the display didn't use the backlight. They don't seem to be widely manufactured in my attempts to look for them... I should check again!
Sharp’s Memory LCD, I think. Combination of SRAM cells to hold state in each pixel and improved reflexive backing, otherwise normal LCD, so data input can be stopped without losing contents.
Also to parent comment: backlit LCD without backlight looks like brownish tinted frosted glass. Transreflexives look like calculators and never like a paper. There were high contrast monochrome variant in those Memory LCD products and it looked like half silvered mirror, respectively.

#35If you don't need refresh, a drawing board can be suitable. You can use this. https://m.aliexpress.com/item/4000550295706.html?pid=808_000... OLED can work very well and I have used it for night reading over the eink display Kindle use. You may be interested in reflective LCDs like epaper too. A window outside is better for weather and writing a todo list is a better reminder. If you change your goal from remembering…
In fairness their children haven't done anything in the tech space or much of anything near tech/science. Of the 7 children: Jobs kid's one is a writer, celebrity son, goes to school. All Standford grads or attending. Of Bill gate's kids one goes to art school, the rest not much.
I would not copy them unless you have the billions for them to fall back on.

#36Since the demise of Pixel Qi, does anyone else have a credible laptop screen based on e-ink, that has a high enough refresh rate to be usable, and/or the ability to switch from transflective/zero-power e-ink mode to a normal screen?
E Ink proper seems to require high voltage and current to refresh. It makes sense because power will be “amortized” but refreshing it often makes it just a high power high contrast device.
Other “e-ink” displays has way too low visual quality and markets don’t like that. Brighter backlight LCD and huge battery usually solves the same problem better. IOW/IMO if such technology is to hit the market it would need to be closely comparable to LCD.

#37Have you looked at https://remarkable.com/ ? It's a little smaller, 12" diagonal. Dasung sells a 13.3" e-ink monitor: https://www.amazon.com/Dasung-Paperlike-13-3-E-Ink-Monitor/d...
Looks like I can get the Dasung for $1200 used...
It’s a pity because I’d love that thing to read the web on actually.

Not only are Onyx expensive; they're basically unusable. A rooted Kobo H2O with koreader in landscape mode is vastly better.
Sony is apparently still selling the DPT-RP1, and it still doesn't connect to Linux or read DjVu. I guess at least it has an OSX client.

Can anyone comment on the difficulty (for a hacker) of using Remarkable with Kindle books? I have a Kindle already, if that makes a difference in generating DRM-free files of content I already purchased reading rights to.

In higher level education they also use the familiar chalkboard rather than electronics. I use this not to say the merits of their children's occupations (regression to the mean is common in families of great achievements) but as a warning of what people in tech see as a threat to their own children's well being. Electronics are wonderful but not for everything. If screens work better for you, perfect! They have been a hindrance to me, addiction to screens is very common today and I am weak enough to fall into they category.
