I can't wait for a proper ACEP eInk device. I have a "colour" eInk with the RGB filter, but it's horrible. There is a very visible "screendoor" effect. Basically you can see each individual pixel of the filter layer. I wouldn't recommend it.

#12So what's the over-under on E-ink replacing our current computer monitors much like we've come to replace cathode ray tubes.
People have slowly become accustomed to high refresh rate displays. So that's a big no on e-ink displays unless they manage get them to 60Hz+ somehow
The devices I've seen with color e-ink need to intermittently flash the screen. I could live with a slow refresh rate, but having my screen flicker black once or twice a minute is a deal-breaker.

#14This is second hand info, so sorry if it's totally wrong, I'll edit this: E-ink tech is great, but patents and other paper-limitations are slowing down developments of cheap e-ink devices devices, and e-ink will become "great again", when patents expire. I personally see many, many usecases of e-ink all around me, but the prices are way too high for anything that is not either really small or a repurposed old existin…
Out of interest, is there actually any evidence that patents are preventing developments in this area?

I've been waiting for e-ink displays to become affordable since the first Raspberry Pi came out. I'm still waiting.
I think Dasung and Mira has e-ink 25" monitors, but they are just getting released, so not sure how good they actually are. I also wonder how they worked around the e-ink patents.

https://dasung-tech.myshopify.com/products/dasung-25-3-e-ink... Monochrome. It has "turbo refresh tech" but unclear what that really means; with e-readers, similar verbiage just means it's less bad. The resolution and pixel density is very nice. The prices would have to come down by at least a factor of 3 though, IMO. I'd take the under.
E-inks screens don't have to be monochrome. I have one with black, white, and yellow. The hard part is fitting a range of color pigments in the pixel units, so the first e-inks so far have had 2-3. At only three colors, black, white, and one shade makes most sense for information contrast. But nothing says it can't be red, green, and blue... and as the technology miniaturizes, we can fit three in the space of one, maybe achieve sub-rotation, and thus achieve full color range.
Actually if they're pigments... we're looking forward for CMYK. That's 4 separate pigments stuffed thrice into a pixel, that need to rotate separately! Possible? Difficult.

#18Has there been any progress on extending e ink lifespan?

I want to hook up a small e ink screen to a pi and use it with my mechanical keyboard as a modern typewriter of sorts but the prices on eink are so prohibitive it doesn’t seem worth it.
The response time is what makes devices like this kinda annoying.
Re: How E Ink developed full-color e-paper
#20Every time an E Ink article is posted the patent defeatism is inevitable. I’m curious if there are other techniques to implement reflective(?) displays being explored that wouldn’t fall within the scope of E Ink’s defensible moat, or, if their parents are simply so broad as to stifle most hopes of accessible solutions and broader consumer/professional adoption.
Frankly, I’m quite sick of straining my eyes and circadian rhythm for 8hrs+ a day
