Over the previous couple of years, I’ve examined a handful of gadgets with paper-like screens. All supply, kind of, the identical set of advantages. A panel that looks like paper to the contact, cuts down on blue gentle publicity, and — if attainable —even eschews the backlight in favor of a display that displays gentle as a substitute of emitting it.
A number of the concepts, especially those from Onyx, have been spectacular. However the largest problem has been the panel pace. Onyx’s tablets are nice, however they usually have low refresh charges that dramatically decelerate the scrolling pace, even for one thing as mundane as studying a PDF.
As you leap to the colourful e-ink iterations, ghosting artifacts and poor constancy depart a jarring impression. There’s at all times some visible caveat. In any case, for gadgets that rely solely on onscreen interactions and serve all that data on a panel, why ought to it ship a severely underwhelming expertise?

Taiwan-based HannStar, which makes shopper digital devices beneath the HannSpree model, has a radical answer within the type of its EcoVision display tech. It’s a full-color show that is available in each reflective and backlit codecs, however most significantly, it’s a 60Hz panel.
For context, the iPhone 16 additionally serves a display that reaches a 60Hz refresh price determine, which suggests the HannSpree EcoVision Panel is almost as clean because the one on Apple’s newest smartphone. What we now have for testing right here is the HannsNote 2, an Android system that could be a glorified one-of-a-kind paper-like studying slate.
What makes the HannsNote 2 so particular

Earlier than we dig into the specifics of simply how HannSpree cracked the code for a 60Hz “usually scrolling” expertise on a paper-like display with none backlight, let’s briefly go over what a sunlit display is all about.
Most screens round us produce their very own gentle, both in front-lit or backlit format. In addition they supply the flexibility to regulate the brightness output relying on the exterior gentle ranges and the pressure your eyes can take. Consider a Kindle, a daily pill, or a smartphone display.
Then there are reflective screens, which lack light-producing {hardware} inside. As a substitute, they depend on the ambient gentle to replicate and present content material on the display. The entire strategy is definitely a fusion of sunshine absorption and reflection via a layer of pixels, that are illuminated to point out photos after ambient gentle is mirrored via it.

Theoretically, this strategy guarantees a lot decrease energy consumption. Plus, it rids the display of blue gentle emission, and the reflective strategy is simpler on the eyes as nicely since that’s technically how we see the remainder of the world round us.
The Onyx Boox Go is one such instance of a reflective display with a monochrome strategy. Then, there may be the Daylight Computer DC-1 tablet, which takes a hybrid strategy by providing a sunlit and backlit mode for viewing content material on the panel. But, each gadgets solely present a black-and-white viewing format.
The know-how at play on the HannsNote 2 is the HannStar Argentum Birefringence system, which guarantees as much as 80% decrease energy consumption than a daily LED-backlit panel. Along with the colour output and better refresh price, the replace response has been lowered to single-digit millisecond ranges.
A very particular pill show

One of many largest attracts of the HannsNote 2 is the full-color 10-point multitouch panel, which is able to producing a formidable gamut of 16.7 million colours at 24-bit colour depth. The decision just isn’t precisely eye-popping at 1200 x 1600 pixels spanning throughout a 3:4 panel, however for studying and watching the occasional video, it will get the job accomplished.
The slate itself is simply 4.9mm throughout and weighs solely 350 grams. The construct high quality is strong, and due to the wraparound leather-based end on the rear shell and one of many vertical edges, the HannsNote 2 feels extra like a classic leather-based pocket book. You get the same old set of energy and quantity buttons and some holes drilled on the rounded edge for audio output.
The EcoVision panel is improbable, regardless that its floor feels extra like the kind of TFT resistive display that pushed touchscreen telephones into the mainstream for the primary time. The viewing angle just isn’t too unhealthy both, at 120 levels. There isn’t a lot of a colour shift to be seen right here, similar to a median LCD display.
However as you progress the slate, the onscreen content material will get dimmer or brighter (learn: exhibits glare) relying on the route of sunshine beams falling on it. In a nutshell, what number of eyes can comfortably learn content material on the HannsNote 2’s display, or simply how a lot angular freedom a single particular person can take, relies upon fully on the supply of sunshine round. That’s each and unhealthy factor.

Below the solar, you received’t should fiddle with the angle at which you maintain the slate. Indoors, you would possibly battle, because the extra overhead synthetic gentle sources there are, the tougher it will get to keep away from the robust glare artifact on the display. HannSpree tells Digital Tendencies that it’s launching paper-like tablets with a front-light function quickly.
Sitting in a espresso store, I couldn’t keep away from these white reflection patches from the lights round me. Furthermore, the brighter it’s, the extra jarring it seems on the HannsNote 2’s display. When you’re studying one thing with a darkish background (like Batman comics) or watching movies, the ambient glare proves to be fairly a nuisance. Additionally, needless to say there isn’t any strategy to modify the colour depth (not like the Onyx Boox tablets) or play with brightness output, so that you’re left with no different choice however to vary the angle at which you’re holding the pill or shift your spot till you discover a place that takes the bottom reflection toll on the colours.
I work predominantly on an iPad Professional with a shiny OLED display. I really like its colours and sharpness, however the eye fatigue is inescapable. The HannsNote 2’s display is extra light on the eyes. After a writing session lasting about 4 hours in a backyard, I didn’t really feel any stress in my eyes, which is uncommon.
The shine, and the stumble

Now, what I’ve described above are principally outlier instances. Have a look at how legible the EcoVision show is in a espresso store with varied sorts of LEDs and hanging lamps hooked up to the ceiling. The one nagging situation is the dearth of correct distinction, which may be achieved towards a white background or a backlit structure, neither of which is accessible right here.
On the optimistic facet, HannsNote 2’s colour show is kind of nice. It seems one of the best beneath pure gentle, and due to the fluidity of a 60Hz panel, the contact interactions don’t really feel out of character, particularly the zoom and drag gestures. Sketching with a USI stylus was a no-fuss expertise with none points.
I haven’t encountered any make-or-break hurdles integrating it into my workflow. From studying on the practice to utilizing it as a secondary reference display for maintaining a tally of social feeds and office chats, the HannsNote 2 has proved to be a useful addition. There are sufficient pixels for an easy studying session or selecting up decor concepts from Pinterest. Simply don’t push it at duties the place you cope with many colours. A perceived shade of jade inexperienced on the EcoVision panel turned out fairly completely different after I seen the identical put up on the iPad Professional’s OLED display.

The issue, after all, is the colour of the ambient gentle. For instance, in case your workspace is heavy on yellow gentle — otherwise you’re a kind of “RGB in every single place” souls — the EcoVision panel can take you for a colour reflection trip, and never essentially in a great way.
HannSpree’s EcoVision panel is claimed to supply a “20:1 ambient distinction ratio (ACR)” towards higher visibility in daylight and with a glare-free strategy. For probably the most half, it’s true. Not seeing reflection artifacts on a display is a aid. The overall absence of shadow artifacts from the earlier body – an issue for each different e-ink display on the market – is a sport changer.
It’s a perk that must be seen and felt in particular person. Pure gentle or in any other case, the graceful paper-like display on the HannsNote 2 is a pleasure to make use of. It feels completely different to the touch and think about, but it additionally stands out in its personal distinctive means.
What’s not so good about it

That is the place you pay the innovation tax. The EcoVision Paper Show finally ends up sucking much more energy than a median reflective or backlit e-ink display, all due to that prime refresh price panel.
My each day utilization sample concerned studying in a Courageous browser and sometimes checking Gmail and work apps like Slack and Microsoft Groups. The common mileage I acquired was about 35 to 40 minutes of utilization for every quarter of the battery juice.
The newest evaluation of battery drain within the Settings app stated that with 75% battery within the tank, the HannsNote 2 would final solely about 2 hours and 5 minutes. These are critical battery nervousness figures. After enabling adaptive battery and power-saving mode (which prompts darkish mode, delays notifications, and lowers background exercise), the mileage received’t improve by any wholesome margin.
Even Hannspree notes that the built-in battery is just ok for two to three hours of video watching. That’s not fully sudden, because the slate solely comes geared up with a 2.200 mAh battery, which is half the dimensions of a median smartphone battery.

On the flip facet, it’s a small battery and fills up shortly. On just a few events, I merely reverse-charged it with my cellphone. Sure, you won’t at all times carry a USB-C cable, and there’s no reverse wi-fi charging comfort accessible right here, so there’s that.
It’s fairly evident that the lion’s share of bills went into the show tech. The machine is powered by a quad-core Rockchip RK3566 silicon with 4 Arm Cotex-A55 cores paired with 4GB of RAM and 64GB of storage. This isn’t precisely the type of firepower suited to an Android pill. A studying system? Nicely, it’s greater than sufficient. Every part is clean for studying, video watching, engaged on a doc with a stylus or Bluetooth keyboard, and scrolling the social media feed.
Simply don’t burden the slate with loads of background exercise or try and run video games. Chess and card video games? Truthful sufficient. Something with animations and graphics pizzaz? Don’t do this. You’ll really feel the stutters. Fortunately, no worrisome thermal points have popped up for me up to now.
Who’s the HannsNote 2 for?
Nadeem Sarwar / Digital Tendencies
So, right here’s a very powerful query. Do you have to get this system? Conversely, who’s the target market? “Pill or iPad customers who need a show with eyecare options. The EcoVision Paper Show provides true 8-bit, non-FRC (body price management), flicker-free, anti-glare, and 0 blue gentle options,” HannSpree tells Digital Tendencies. The corporate can also be eying Kindle and Kobo followers searching for a swanky show improve.
The HannsNote 2 at present goes for the equal of $350 in Europe. Hold that price ticket within the context of what you search from a pill. Would you like a no-frills studying system that’s simple on the eyes, ideally one thing like e-ink, and that may take notes whereas mimicking the texture of paper? If the reply is sure, this pill will give you a silky clean expertise, not like every other eye-friendly paper-like panel. How about you add just a few million colours to it after which make it really feel as regular as an iPhone’s display?

Then possibly add the flexibility of a full-fledged Android expertise that permits you to obtain any app of your selection — studying, streaming, social media, or work chat. That’s even higher. Plus, there’s even a entrance digital camera, simply in case. Total, I’d say that’s way more than a typical studying pill can accomplish, together with just a few standout exclusives like a “regular” 60Hz display. That’s primarily the HannsNote 2 for you. It’s a next-gen show tech slapped on a slim slate with the added comfort of Android.
The one caveat is that it wants ambient gentle to weave its magic. When you’re a backyard or cafe studying aficionado, you’ll love this one. For people preferring the consolation of their mattress or sofa to complete a gripping e-book embraced by darkness, nicely, make it possible for the bedside lamp is on.
“Our tablets may serve shoppers who need a system particularly for outside use,” stated HannSpree when requested in regards to the market actuality. “Whether or not this market exists or not stays to be seen.”
To the corporate’s credit score, the tech works.
