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)

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.

Would greyscale be ok? If so, you should be able to delaminate a panel and replace the backlight with a reflector. If you'd do that with a color LCD, you'd have a very dark image, however.

What about a trans reflective display? I don't know about them being high refresh though.

Here's an interesting one: https://www.j-display.com/english/news/2016/20160520.html
