I'm using the Dasung Paperlike HD and I really like it for writing code. 13 inches, but it's real nice. I imagine in 5-10 years or so, we'll see what you're imagining.

Maybe. I feel like e-ink could have an iPhone moment. It just needs more attention. Remarkable and similar products are analogous to pre-iphone palm pilots.

Also interested in reflective (non backlit) LCDs. The only ones I've seen are very small.

Like the sharp memory LCDs?

They're pretty cool but I think the limiting factor is demand rather than technology (although they do have a pretty niche construction in that the control sillicon is AFAIK actually fabricated inside/along the LCD panel)

If you're interesting in building your own you can get a 12" one from waveshare: https://www.waveshare.com/product/displays/e-paper/12.48inch...

This is the black/white one, they do a black/white/red one too. But beware, they take really long to refresh (the red color takes several refreshes to appear). And the one with red is on backorder till June.

It can be powered by a raspberry pi (or ESP32 or Arduino) and is (much) cheaper than the ereader options of the same size: Only about $170.

PS Beware: You can't simply start up a user interface like X-Windows on it. You have to write software to display on it. The display is addressed in 4 separate sections so it's not super easy.

> It doesn't necessarily have to be E-ink proper, but I like the idea of having something that doesn't emit its own light. Such as an older LCD panel without a backlight? It doesn't sound like you're looking for anything special here.

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 reflecting off the paper, or fully opaque.

The LCD still needs continuous power, but far far less than the backlight.

That might end up being a superior balance... a small amount of continuous power, with the benefit of up to 60hz refresh rate if you want it.

Could you write a review on it? I've been contemplating getting one for the same purposes but I'd really like to hear some pros and cons before committing

I'm actually more interested in a high refresh rate, non backlit monitor. Power isn't really an issue for desktops, so that part of eink doesn't appeal to me. I'm trying to limit my time looking at illuminated sources.

Something like [1] with no front light.
