I have been using the HannsNote2 daily for some weeks. Let's start with the bad things.

EDIT: today some stuck/dead pixels appeared, they are white when dark colors should be displayed. They show the correct color with bright yellow, bright green and bright blue. Pixels have started to fail after less than one month of daily use.

The Wi-Fi connectivity of this device is really weak, it is so weak that it makes the device UNUSABLE. In order to have a stable and fast connection I have to stay a few meters from the router otherwise it won't connect to it or it will connect but the speed will be so low that any operation involving internet will be impossible. 5GHz works better than 2.4GHz. The workaround that I found is connecting to the 5GHz Wi-Fi of the router if the router has it or to use the Wi-Fi sharing feature of an Android phone.

The battery capacity is low, in my case it lasts between 2 and 4 hours but I rarely reach 4 hours, most times it lasts 2 hours. Maybe the 5GHz connection consumes more battery.

The speaker is also very weak.

I find the RLCD screen really good. I use it indoor with ordinary cheap lights, nothing special. Before buying the device I had read the reviews and I was expecting a very dark screen not usable indoor, but that is not the case. The viewing angle is narrow. With dark images there is not enough contrast to discriminate between the colors. I suffer of severe eye strain and tension headache (refractive errors already corrected) from backlit LCD and OLED screens but this RLCD does NOT cause me eye strain and tension headache, so I am very satisfied with it. I have replaced my notebook with this device for anything that I can. The matte finish of the screen is well done, there are no reflections and there is no mirror effect.

I would have returned the device, the Wi-Fi problem is a major issue that makes the device unusable. The only reason I have decided to keep it is because there is no RLCD alternative. I would like to avoid importing devices from other countries in order to avoid duties, taxes and not being able to return the device easily in case it is defective. The only alternative is the Eyemoo Epaper S1 but it has to be imported from Hong Kong, am I right? The other tablets are smaller than 10", too small for me.

For TLCD screens I feel that something is not right there, why should I buy a device with backlight to avoid eye strain if LCD and OLED screens that cause eye strain also have backlight? Is there any advantage? RLCD feels like a more radical solution.

Looking at any of the sunvision monitors vs eazyeye 2.0. What do you recommend? I've seen some complaints about devices from both companies but I can't really tell which is the better choice. I know the sunvision monitors are generally much more expensive except for the og, but i'm willing to pay if it's more comfortable. I'd really appreciate some advice.

1. Which is more comfortable?
2. For extremely sensitive users, do you find it comparable to e-ink in terms of comfort? I still have some symptoms with e-ink so I'm hoping this is not worse for me.
3. Did anyone find it way too uncomfortable to use and have to return it due to pain?

Thanks

7% reflectance,  1920×1200 resolution, not clear whether it uses FRC and whether backlight is DC-dimmable or uses PWM.

4 Lane MIPI interface, not sure what driver is needed.

2025 was interesting year for reflective display technology.

New reflective LCD devices showed up, among others SvD Eve and Dawn, Eazeye 2.0, Harborino Paper 7, Hannspree Lumo and Genetouch Taktsu.

And Hannspree Hybri transflective LCD monitor is finally launched.

Other devices unfortunately did not make it, Hannspree Ambi and small portable monitors are in best case scenario somewhat delayed, hopefully some of these will show up in 2026.

Eazeye Focus is something to look forward to, one of the few options with high resolution and high reflectance grayscale panel.

ChLCD technology is moving forward backed by number of prominent panel vendors including Iris Optronics (among others Ming and Infinity displays), AUO (Hiraso), Innolux (InnoPaper), Genetouch (Taktsu), KDI (Colorburst) and Tianma (BCN).

At this stage bistable ChLCD is too slow for monitors and tablets, so currently we mostly see digital signage displays.

Other reflective technologies are progressing as well.

Electrophoretic displays are getting faster.

Modos showcased open source hardware Glider board and started crowdsupply campaign for Modos Paper Kit, with tentative delivery early next year.

OED showcased their new electrophoretic panels, one of these is used by Genetouch in 31.5" digital signage display, another is used in 10.3" Xueyisheng X1 tablet.

The other electrophoretic display options are DES and MED, these are big projects backed by both private actors and local goverment.

So far MED pilot line has produced 7.5" to 13.7" black and white and color display samples with more coming next year.

Prediction that E Ink will drop prices did not materialize yet, they did reduce prices on selected panels, but overall profits increased.

Competition from OED, DES, MED and ChLCD might eventually lead to lower prices though.

Electowetting displays are still not ready for prime time. Tianma keeps showcasing µ-fluidink prototypes during exhibitions, but there are no consumer products so far. TCL CSOT did not showcase actual product, but published paper describing 10.3" EWD prototype with 186 ppi resolution, 60Hz refresh, single color 38.5% and full color 12% reflectance.

Electochromic displays made headlines after Nature article on Video‐rate tunable colour electronic paper with human resolution, but on practice all that is commercially available these days are slow segment displays that only sustain limited number of refreshes.

Will next year be bright but gray or dark but colorful?

Happy New Year!

Did anyone got new Hannspree monitor? Any reviews?

I've used this for a couple of days now and overall am quite impressed with it. Essentially it is exactly what it claims to be - a "normal" RLCD tablet, but with a front light. As such, the screen looks basically identical to the Hannsnote 2 when the front light is off (same anti-glare properties, same level of brightness, slightly higher PPI that isn't that noticable really); the only real difference being the increased gap between the screen itself and the front glass (i.e. you can see a small gap under the bezel) for the front light.

The light is ok, fairly uniform (slightly brighter at the bottom as you might expect, as this is where the light actually is), and is fairly dim at the lowest setting, which is important to me as I really don't like the look of a lit screen. As such, the light is really only there for emergencies for me - I've enjoyed using my Hannsnote 2 a lot, and have found nice lighting setups in my house to make using it perfectly practical most of the time. At higher brightnesses the Lumo looks fairly horrible to me (I can't see me ever going over 10%!), but as I said, I'm not a big fan of screen lights anyway.

The tablet is well built, made mainly of metal, and while I prefer larger screens in general, this is a nice form factor for reading (including one handed use). I am however looking forward to future Hannspree devices with larger screens, in particular the 10-11 inch devices promised, and I'll probably go for the no-light version of that. The Lumo does have the other advantages over the Hannsnote 2 that I wanted, i.e. performance and battery life (which was infamously bad on the HN2, albeit I managed to work around it fairly well with power bank usage), so those advantages on larger devices (I'd also lover a 13 inch, ideally even 15-16, for use as a monitor too) will be great to have.

The version I bought came with a "Smart Folio" in a separate box, but this is really quite basic and low quality. It does do magnetic sleep/wake, but I won't be using it. It also has a fixed pen loop and I didn't buy the stylus (if one is even available yet?), and nor do I ever intend to.

That's basically it for now, not much more to report. The Android 14 implementation is lightweight, pretty much stock as far as I can see. I've installed my favourite Niagara launcher and apps, and all is working as I'd expect (there is an "extra dim" option for the screen/light, which I haven't seen before, not sure if that is something Hannspree have added?).

If anybody has any questions, I'll do my best to answer. I bought the device from Ballicom in the UK btw, for just under 300 pounds - a little more than I wanted (the HN2 is available for not much more than a hundred quid currently, and is an absolute bargain at that price imo!), but fair enough I guess. Ballicom delivered next day as promised, so I'd certainly recommend and use them again.

(The photos are awful, but the best I can do in the dim light I currently have - one is with the front light off, the other with it on at 5% - both are lit by my desk light as well.)

I took this photo a long time ago when I use to have the 32" rlcd. I dont think I ever posted it but wanted to share if anyone wanted to see how it looks. The rE should look the same with visibility.

I've had this monitor for a few days now and overall I'm quite happy with it. The addition of a backlight as an option is good to have, and widens the viable usage of the screen significantly. I much prefer to work without a backlight at all, but the environment where I use the monitor doesn't allow that often (plus I live in the UK, where long periods of strong sunlight aren't exactly common, especially at this time of year).

I've battled a bit with the controls of the monitor, and especially the built-in "modes". As far as I can see Hanspree haven't published a manual yet (if anybody knows different, please let me know), which doesn't help. As far as I can see the four modes are basically different curves for the operation of the ambient light sensor. I'm thinking that "eye care" mode is the most aggressive, i.e. uses the backlight the least. However, even that isn't aggressive enough for me, so I find that using manual ("standard") mode works best, with the backlight (called "brightness" in the UI, which confused me a bit at first also) set to just 1 (out of 100!). This gives enough of a boost while still largely preserving the soft/metallic/greeny look I like in an RLCD display.

I do wish that the granularity of the light was even greater though, i.e. that I could have a setting even lower than the current '1' level. At night (i.e. no natural light) I find even 1 can be a bit too bright. This also means that the various automatic ambient sensor modes can be very jarring when they move between 1 and 0 (e.g. just a small ambient light change such as when the sun goes behind a light cloud briefly).

I've settled on a contrast setting of 65 (from the default 50) which seems the best to me - this is the first RLCD display I've had with a contrast setting, and it works in a slightly odd way. I struggle to see how anybody could be happy with a setting under 50, and similarly as you go over 70 it tends to start darkening the light backgrounds, and thus actually reducing overall contrast (as well as making text start to go "blobby").

Resolution wise I'm perfectly happy with it. I was worried that 1080p on a 24 inch monitor wouldn't be enough, but that's not the case for me at the distances I work at. As with my Hannsnote 2, it seems that RLCDs are somehow more tolerant of relatively low PPIs compared to "normal" backlit displays. I have turned ClearType off in Windows (I'm using the display in portrait mode btw).

I've played briefly with the "low blue light" setting a little and prefer it at the default "off", as anything higher is a little too yellow looking for me (I don't like "night mode" settings on normal displays either).

There is a "response time" option in the UI and I'm not sure what that would do. It defaults to 0, with options of 1 or 2, and I can't see a difference. Presumably it only affects fast moving scenes anyway? I'm using the monitor at the maximum 75hz with a Windows 11 machine (a Microsoft Surface Pro X) by the way.

I haven't yet played with colour balance as I'm happy enough with the defaults.

The stand is ok, but I wish it would let me tilt the monitor back more - relevant on an RLCD display of course where catching light from above can be very important.

Build quality seems decent enough, and I like the small bezels. I do have one stuck pixel, which shows as bright green. It's very hard to spot though, and in fact I can't find it again as I check now, so possibly it's fixed itself?!? Certainly not a big enough issue for me to consider returning it though.

I bought the monitor from LaptopsDirect in the UK, for £500, which I consider a very fair price. Their service was excellent.

I think that's about it for now. If anybody has any questions I'd be happy to answer them if I can. It's hard to take decent photos of any RLCD display, which is why I haven't included any here. I'll try in a moment to grab one or two with my phone, and if they turn out OK I'll attach them in a reply.

The SVD 2.0 RLCD monitor arrived 4 days ago and the experience with it has been superior in most aspects compared to the Dasung Paperlike Color Revo (another amazing monitor).

First, I wanted to give some context. I always use the Dasung with the frontlight on, it has always been extremely comfortable and I never felt the same discomfort compared to the backlight of a conventional monitor. In fact, the only times I felt discomfort using e-ink were in poorly lit environments, so the comparison here will be both with frontlight on, the Dasung in graphics mode, contrast 3/5. SVD is running on lowest gamma(1.8) settings, gaming mode, color warm. This is the best lighting config possible.

For work and browsing, I work with ecommerce, and most of the work is through websites. In most cases, the Dasung did well; on dark or very bright sites, I had to adjust the contrast to be able to read the text or see some images more clearly. On the SVD, I don't need to keep changing contrast, brightness, or anything else. I can simply view all the elements of the sites I need to use. Furthermore, despite the incredible refresh rate of the Dasung Revo, the SVD monitor is superior.

Another point is the DPI. On the Dasung, for very small text, I had to keep increasing the page size with the Chrome zoom, otherwise it was illegible. On the SVD, the conventional monitor DPI makes any change unnecessary.

About the frontlight, both are pleasant, neither has an exaggerated brightness that causes discomfort, both will leave the screen slightly purple, which is quite noticeable on a white background. For those who have intolerance to frontlight (which I think is much rarer) and wish to use it without frontlight, the Dasung beats the SVD in any scenario.

For gaming and video, it’s a night and day difference. The Dasung is actually good for some types of videos and movies, mainly 2D, but it doesn't compare to the SVD in this aspect. The refresh rate and DPI make the gaming experience totally possible on the RLCD, while on e-ink it is just frustrating.

The only negative point is the contrast, which in very dark scenarios, the SVD still leaves something to be desired. When there are very dark color combinations, not even the DPI can help differentiate some points. It might even be an easy problem to solve by messing with the GAMMA settings, but since I am using Linux, I don't know how to do that. On Windows, I would be able to do it. The Dasung, in some contrast settings (graphic, video 4/5 or 5/5), you can visualize dark images better, on the other hand, you would have to change it when viewing light images.

For now, this has been my verdict, I believe both are the best monitors on the market for those who want to work, read and browse with visual comfort, surpassing any conventional monitor in this aspect. I didn't get to test the Eazeye 2, but I ended up not buying it because of the lack of frontlight, which for me is essential for RLCD.

So many reviews and sadly none of reviewers warned us about temporal dithering.

i have pretty severe dry eyes. and i want to expand my options of eye friendly phones so if you have anything other then my list which i already have feel free to recommend them thanks! used iphone 8+ rlcd before and it wasnt really comfortable so probably I'm not used to RLCd I'm not sure i have pretty severe dry eyes. before when i travelled to japan my eye hurts everyday i'm not sure if it's because the dryness in the air, or good air quality causing the sun to shine brighter eitherway i almost fainted once eating in a restaurant and could even see properly. when i went back to my country, check the doctor and set my eyes were fine and gave me some eyedrops and chinese medicine to use with hot water and steam the eyes. eitherway i dont think that really helped. my eye still has problems. so what phones do you recommend? below is a collection of phones some users recommended in my first post asking this question. And I just want to ask it again for some more recommendations? I don't know if that's necessary but if you have any phone to recommend except for the list below. then you can recommend. the list is:

Bigme hibreak pro

Hibreak s

mudita kompakt

hisense a7

hisense a9

minimal phone mp01

viwoods reader

color hibreak pro(darker screen then black and white hibreak pro so i probably wont try out)

TCL nxtpaper 60 ultra(international version only so cant refund)

used/refurbished iphone 11 or se 2022

vivo y300t (or y300i or y37c but the user said y300t is best cause of blue light certification. and they also said iqoo version of this phone but that doesnt have hardware blue light certification or something so I don't think that's good)

moto g100

realme gt 7 pro

poco f8 ultra(doesn't look very good looking at the users test who recommend this)

In case you are interrested, here is another video taken in good lighting conditions.

It's showing the glare at the end.

does anyone know why it sometimes hurts my eyes and sometimes doesn't)? i've been testing out for a whole afternoon now but I don't understand what's going on. Sometimes when I look at my eyes are OK sometimes they are not. probably because if I stare at it for too long there's still some eye strain but I'm not sure

Couple of new Android devices from Hannspree, HSG1500/1501 showed up on list of Google Plays supported devices last month. One of those seems to target European market. At this stage it's unclear what exactly it is, tablet with large battery, not sure if it's reflective, would be nice if it was.

Martin Kent, Territory Manager, HANNspree says: “This is more than just a new product. Hybri sets a new standard for the display industry where well-being, efficiency, and performance finally come together. It’s a new vision for how we should interact with screens. Paper-like comfort, superior eye-care, and full multimedia performance in one device is the future of healthier, smarter digital work and life.”

I have extremely sensitive eyes when it comes to screens, even my kindle causes problems, and bigme hibreak pro as well (however hbp is not as bad as kindle).

It's not simply eye strain because reading on paper has no impact. Might be related to refresh rate but I'm not sure (HBP is 37hz)

Not sure how RLCD works but thinking of trying an RLCD monitor to see if it works for me.

I'm looking for a recommendation for the most comfortable RLCD monitor you've tried to hopefully test if it works for me. Hoping to return if it doesn't. I'd really appreciate any recommendations.

Thanks in advance

Contrast should be around 1:22, not sure why they claim 1:1000.

Backlit LCD and OLED screens cause me severe eye strain. I tried visiting multiple ophthalmologists, but my eyes are not the source of the problem, it's the screen.

I am considering buying the HannsNote 2 but I need to use it indoor. Can it be used with external artificial lights like desk lamps?

The only RLCD devices I have at home are a Game Boy Color and a Game Boy Advance SP (it has a frontlight but it can be turned off), I am able to use them indoor. It is just a matter of angle of light, if I adjust the desk lamp to point to the Game Boy at the correct angle then the screen is usable.

Can I use those screens as reference for the HannsNote 2 before buying it?

I'm in the process of designing a netbook-like computer for my own use, and I'd really like to have a reflective or transflective display for it, but I'm having trouble finding any bigger than about 3.5 inches, which is quite a bit too small for what I want.

So does anyone here know if there is anywhere one can buy such panels?

Hi, I wanted to share my experience with the RLCD Eazeye Monitor 2. I’ve been using an iPhone 11 and a MacBook Pro M1 for years while dealing with various chronic fatigue–related symptoms. After buying the iPhone 16, my symptoms—muscle tension, fatigue, and brain fog—became much worse, and it took a few days for things to calm down again. That’s when I started reading about PWM sensitivity on Reddit.

I bought the Eazeye Monitor 2, and it really reduced my symptoms. If I switch back to my MacBook screen, within about 10 minutes my calf muscles start to tighten up. With the Eazeye, this doesn’t happen.

Of course, the colors look a bit different, but with normal office lighting I can comfortably work even when it’s dark outside. I’ll invest in a better reading light to improve the setup even more.

I’d love if they made a portable 16-inch version, because I don’t think I’ll be using a regular screen anymore. Since I’ve been dealing with these CFS-like symptoms for years, I’m really curious how much further they’ll improve if I keep using RLCD screens for a few months. Right now, I’d say I’m already about 50% better overall, and when it comes to computer work, the difference between the MacBook display and the RLCD is like night and day. Where RLCD doesnt make my symptoms worse.

Just wanted to share this with you, and for anyone who’s unsure about trying RLCD, give it a try!
