#92Lenovo had a dual screen botebook with e-ink https://www.engadget.com/lenovo-thinkbook-plus-gen-2-i-e-ink...
Yes, but the e-ink screen was on the wrong side of the device. People like me and the author need an e-ink display for writing in broad sunlight.
What Lenovo need to do is to make a hybrid version of the ThinkBook Plus and ThinkPad Twist, and rename it as Lenovo BookPad for laptop with a twist-able dual e-ink and conventional monitors [1].

#93Finally a nice hacking project that doesn't use a Raspberry Pi at its core! Every Pi article on HN has the same comments about how old repurposed laptops or nucs/usffs are better for the current usecase, its nice to actually see a project that takes that to heart.

#94I haven't used e-ink for a while, but the last one I did had a refresh rate of something like 1Hz. Is this still an issue with modern technology?

#95Did you record the difference in battery life before/after the eink monitor?
Re: Building an E-Ink Laptop
#96I wish I had a large e-ink display for coding. I imagine a large screen would be prohibitively expensive, and the latency will be terrible. Too bad. It would be nice for my eyes.
Dasung recently revealed 25 inch eink monitor. https://www.youtube.com/watch?v=xTok6imfgoM
There was an actual picture of one on /r/eink and the screen surface was glossy. That's certainly curbed my enthusiasm.

When does the patent actually end? I see it noted here that the invention was 1997 and a typical patent is 20 years? What's the missing variable? (I know nothing about patents nor e-ink besides my paperwhite)
It is sad to see that this article itself is literally citing a throwaway HN comment about patents and E-Ink as if it was a fact. I questioned the veracity of that claim and never got a response from the poster. I'll paste what I last commented about this because I'm already giving up trying to get any form of sane discussion on it. " As I have stated, I was looking for evidence or proof for OP's claim about patents…
Thank you for this information!

Power consumption is not the only thing going for e-ink. The major win for e-ink IMO is readability in direct sunlight. If it's a nice day outside I have to stay indoors (or at least in shade) in order to do work. The only reason is that I can't see my display well. As noted, we already have e-ink phones that can do both colour and video[1], while there is some ghosting it's getting to the point of usable. Just need…
But other screen technologies have actually _better_ contrast than eInk in direct sunlight (e.g. reflective LCD, mirror-backed). State-of-the-art eInk technology these days has actually WORSE contrast than in the early days! -- https://blog.the-ebook-reader.com/2021/01/20/contrast-on-e-i... (proving how much people care about it) eInk's primary advantages are power (and only if your idle period is long enough; if you…
Transflective LCD, ie pixel Qi.. look vastly more difficult to see in sunlight; https://www.youtube.com/watch?v=5UEqd-AnGeI
The company also doesn't exist and only produced 10" 1024x600 screens, which are barely usable. If you know of another usable product, or have anything to back up your claims, please do share.

> Demand doesn't bring prices down. Or not much anyway. In my experience in the display industry, the main driver of price is cost and the main driver of cost is volume. If a customer puts in a signed escrowed order for a million displays lilke what Apple did, then processes get scaled, factories get built, and per-unit prices go down. That my understanding of how 6" matrix E-Ink displays went from costing thousands…
> I can't understand what exactly you're talking about. I'm talking about exactly this: if a company holds patents on a technology, other companies can't improve the same technology (using parts of the patented tech and improving specific aspects with inventions of their own) without licensing it. > This extraordinary claim requires evidence. Nothing extraordinary, and it's not about E-ink being cheap or expensive, i…
> if a company holds patents on a technology, other companies can't improve the same technology
You're making a claim equivalent to saying Microsoft holds patents on operating system technologies, other companies can't improve the same technology.
I'm guessing you're not actually involved in the display industry because you chose not to reply with a clearly defined specific problem that is blocked by patents. I actually work in the display industry so I just see the repetition and self-citation claims (OP's article refers to yet another HN throwaway post) on HN as being disappointing.

#100What you didn't say is that Dasung displays cost thousands of dollars. It's just too expensive to play with.
