- How awesome would it be if it was reasonably priced AND doubled as a large eReader ?by locusofself
- The Crowd Supply website mentions the high power consumption but it would be great if I could connect it to a smartphone to work on the go!by MrPapz
- Dimensions of monitor are: 315 x 254 x 16 mm - but what are dimensions of visible screen ? - is it enough to match A4 format 297 x 210 mm ?by t23414321
- I just wish someone would look at the input side, too. I want true digital paper that I can draw on in real time already. Not the laggy nonsense that even stupidly overpowered tablets can't seem to get passed.by TheRealPomax
- Last time I read about them (here in HN) somebody highlighted that the problem wasn’t to get them to function at a high refresh rate, the problem is they stop being energy effecient at that rate. Now I mostly skimmed the article but I couldn’t find any information regarding that.by zero0529
- I think that's true, but energy efficiency is only one potential benefit of epaper displays, and not one that is a goal with this product.by abrowne

- If you update that often it’s probably going to chew through the battery though.by dyauspitr

Nothing to add, but it bears repeating. A shimmer of indie tech resilience
by dleeftink - I've seen these portable e-ink monitors available for nearly 10 years now, but this one seems to be the first that's responsive enough for general usage, which is a big step forward. Out of curiosity, if anyone here has one, what do you use it for? There must be something people are using them for if they've been a product niche for so long, but I can't think of what I would do with a standalone 13 inch e-ink monitor.by ndiddy
- > two-person startup is back fund-raising for Modos Flow, a 13.3-inch color e-paper monitor with a higher native resolution of 3,200 x 2,400, touch input, and a 60Hz refresh rate
Those are some mighty specs. Godspeed.

- Between this, the Daylight computer (I know it's RLCD), and some of the flagship Boox devices, I'm very excited for where alternative display technology is going in the next couple years. Displays that you can use outside and that drain the battery way slower open up so many possibilities for auxiliary devices. My ideal device would be an ultralight android tablet with a keyboard case and an outdoor display good enough to watch youtube on, that needs to be charged less than once per day. Hopefully this product is super successful and Modos move on to standalone devices next.
There are counter trends, like Garmin discontinuing their e-paper smartwatches. But hopefully that has more to do with that market being too narrow for viable alternatives, and not a fundamental issue with the economics of the displays themselves.

Wait what? Do you have a source? I can't find anything about that, and I see the Instinct 3 is still being sold. Very disappointing if so, as that line has been the perfect pebble replacement for me.
by efskap - As a defense of Garmin, even without reflective/transflective/whatever displays (which would be better in sunlight), they still manage decent battery life. I can easily go a full week without charging mine, or several days with a daily ~1hr activity which uses GPS. It's certainly nothing compared to the ~month I managed on my previous watch, but plugging it in during my shower every few days totally eliminates battery anxiety, so I'm satisfied.by delecti
- Pebble is back, with MIP reflective LCD. I have one. It's great.by afandian
- Been casually following the ePaper/eInk device space for years now and Modos is one of the more exciting developments I've come across in the space. Seriously impressive.
That said, I'm curious what impact the increased refresh rate might have on a Carta panel's longevity. I assume the physical medium that allows each 'pixel' to be on/off has a certain tolerance after which the screen begins to degrade beyond a usable state.
Separately, I also want to understand more about how Wenting's approach differs (or not) from the flickering modern displays use to emit a picture, and, whether the direction actually addresses eye strain or reproduces the same issues (I'm assuming are) inherent in LCD/LED displays — i.e. it's the flickering that strains our eyes, not just light.
Maybe someone more versed than I am in this space would know. After 10+ years of computer work... my eyes hurt and I really want this to be a game changer.
by empalms - In normal use, we don't expect fast refresh to significantly reduce an E Ink panel's lifetime.
The E Ink material itself is long-lived, the main stress is on the driving electronics and waveform behavior during refreshes. Our approach doesn't add extra refresh cycles, the display starts responding sooner, which improves perceived speed without adding extra refreshes.
So far, fast refresh hasn't been the dominant failure mode in our testing. Physical stress, bending, pressure, heat, and moisture are much larger risks.
On eye strain: E Ink is reflective and bistable, so a static image doesn't require continuously emitted light. Fast updates can still produce artifacts like flashing, dithering, or ghosting, but that's a different issue from a display that continuously flickers.
So I'd say this addresses an important part of the problem, though comfort will vary by person.
Also I recommend checking out the following resources:
by alex-a-soto - There is an awesome YouTube video about this from the person who made it: https://m.youtube.com/watch?v=nHbA2-_qzH4by varun_ch
- I found the video on YouTube before the IEEE article. It's a fascinating story.by techwizrd
- Wow, I'm glad to see that person is getting some more recognition for this work.
A claim in the video that I can't verify but makes economic/logistic sense is that the speed problem isn't the panels but the controllers. The current crop of controllers are optimized for low power, which fits the e-reader use case but that is not optimal for the interactive use case.
by adolph - I was watching the video the other day, and my jaw dropped. Wenting is a display-technology beast. Watch his other videos too; he seems to be able to squeeze every last bit of possible performance out of every kind of display, and then some.by deepspace
- Okay, that video is great.
Product questions that I couldn't find an answer to. From https://www.crowdsupply.com/modos-tech/modos-flow, I see "On the go, you can power Flow at up to 40 Hz with a single USB Type-C cable. At a desk, you can connect additional power and take advantage of its full 60 Hz refresh rate."
1) This surprises me a bit... is USB-PD incompatible with DisplayPort alt mode, or is this just based on an observation that display port devices tend to give limited power output?
2) Is every DisplayPort alt mode host able to give enough power to run at 40 Hz? In particular, can this be driven on the go directly from an iPhone?
3) Is that second USB port usable as a data port hubbed to the device when powering over the DisplayPort port?
4) I know it's possible to provide power from the display back to the host device when using DisplayPort alt mode -- when powering the display from the second USB-C port, is the connected device also powered?
The two use cases that would be super interesting to me is plugging this in to my iPhone or similar on-the-go, and plugging a USB-C keyboard into the second port on it for quick e-mails at the coffee shop and similar; and plugging this in to an iPhone, plugging my power bank into the monitor and keeping the monitor in high-power mode and the iPhone charging while working with a Bluetooth keyboard.
Obviously I don't expect it to handle these use cases out of the box, but... open source! This is really a question about what the hardware design is capable of, not the current software/firmware/FPGA capabilities.
by addaon - This link is way more interesting than the original ieee.
It was submitted to HN 2 times already but unfortunately it flew under the radar: https://hn.algolia.com/?q=https%3A%2F%2Fwww.youtube.com%2Fwa...
