Android Central Labs
Android Central Labs is a weekly column dedicated to deep dives, experiments, and a centered look into tech you did not know you wanted. It covers telephones, tablets, and the whole lot in between.
Eye well being has develop into more and more extra essential as our world turns into crammed with screens. Most individuals have a look at a display now greater than at every other time of their lives, so it is smart to discover a sort of show that is not going to trigger you hurt.
Nevertheless, not each display sort is created equal, making some gadgets higher for particular duties than others. For this specific venture, I’ve been utilizing the greatest e-ink pill, the Boox Tab Extremely, in addition to the LCD-based TCL Tab 10 NXTPAPER 5G pill, and the OLED-based Honor MagicPad 2. Every pill’s show works very in another way however all have the identical objective: to be higher in your eyes for the lengthy haul.
That is good as a result of the newest analysis on mild and show flicker exhibits that some sorts of shows could cause well being issues over time, together with migraines and eye issues. Fortunately, this identical analysis is pushing firms to make shows which might be much more eye-friendly, and three applied sciences are main the cost: e-ink, NXTPAPER LCD, and, surprisingly, OLED. Which one is best for you? Let’s have a look.
E-ink
Every of those three show applied sciences “attracts” the picture very in another way and even shows mild utterly in another way.
E-ink shows
Finest for studying. Made up of bodily spheres which might be magnetically charged and do not transfer between frames. Extraordinarily power environment friendly because it does not want fixed voltage to function and may keep on indefinitely with out energy. Watching movies and enjoying video games is not doable on older e-ink fashions however some newer gadgets just like the Onyx Boox Palma are extra possible.
E-Ink guarantees to be essentially the most eye-friendly show of all as a result of it doesn’t flicker the way in which different kinds of show tech are vulnerable to. E-Ink makes use of positively and negatively charged white or black pigments, that are located between a transparent fluid. You’ll be able to see this within the picture above which exhibits what the Boox Tab Extremely’s show seems like below a microscope in comparison with the OLED show on the Honor MagicPad 2.
When an e-reader just like the Boox Palma attracts a picture — just like the textual content in a ebook or an image in a manga — the pigments are energized to create a selected degree of grey after which keep in place till moved once more.
Which means e-ink shows are extraordinarily battery environment friendly since they solely require energy when drawing. LCDs and OLEDs require fixed voltage to function and keep a picture on the display. Moreover, e-ink “accepts” mild equally to paper, so it’s extra viewable as ambient mild will increase. Studying on the seashore with an e-reader is a pleasure, whereas it’s practically not possible with an LCD or OLED.

All fashionable e-readers use an non-obligatory frontlight, which suggests they’re lit in another way from an LCD or OLED in the event you select to show the sunshine on. A frontlight is usually located across the edges of the show and factors at a downward angle.
Due to e-ink’s distinctive light-accepting properties, mild is then carried throughout the panel and evenly lit. All Onyx Boox e-readers that I’ve examined don’t use PWM flickering to dim the sunshine however precise DC dimming to cut back voltage to the sunshine, making it very comfy on the eyes.
The draw back of e-ink is that it’s not inherently designed for shade or video content material. You will discover fast-refreshing e-ink shows just like the one on the Boox Palma that will let you play video games and watch movies, however the expertise is a bit of bizarre because the framerate is low.
It isn’t not possible to observe movies or play video games on sure e-readers — the Boox Tab Extremely I’ve used for this text is a superb instance of 1 that does not refresh quick sufficient for these use circumstances — but it surely’s not as good to view this type of content material an on e-ink show as it’s an LCD or OLED.
Likewise, shade e-readers typically have a diminished shade palette in comparison with LCD or OLED, which means they’re solely best for studying.
The Boox Palma 2 is the proper e-reader for on the go use. It is the scale of a cellphone however options an e-ink Carta 1200 show that is simpler on the eyes than your cellphone, plus a refresh charge quick sufficient to do extra than simply studying books.
NXTPAPER LCD
NXTPAPER LCD
TCL’s spin on LCD tech features a diffusion layer to melt the picture and a matte layer to cut back glare. Seems extra like paper however not as “genuine” as e-ink. The backlight makes use of correct DC dimming making certain zero mild flicker, however TCL’s use of shade dithering means pixels flicker to artificially deepen the colours. NXTPAPER options three completely different shade modes together with full shade and a excessive refresh charge that is nice for movies and video games. It isn’t as energy-efficient as the opposite two show sorts as a result of the backlight does not have zone management.
TCL’s NXTPAPER know-how is a reasonably new riff on older LCD know-how. Like conventional LCDs, NXTPAPER makes use of a grid of tiny crimson, inexperienced, and blue pixels illuminated by a separate backlight to show what you see. The largest distinction is within the numerous layers that separate the pixels and the sunshine itself.
TCL has packed a light-weight diffusion layer and an anti-glare filter onboard. This diffusion layer makes it troublesome to see particular person pixels, even below a microscope, giving the sunshine a stunning “comfortable” high quality that no different show tech has.
Moreover, TCL NXTPAPER backlights are utterly DC dimmed, so there’s no flickering in any respect. All in all, that is the closest factor you’ll discover to the eye-friendly mild offered by an incandescent mild.
TCL has packed a light-weight diffusion layer and an anti-glare filter onboard, giving the sunshine a stunning “comfortable” high quality that no different show tech has.
TCL says that is the Goldilocks show tech because it’s received a wider shade vary than e-ink however does not sport the cruel look of an OLED. The TCL NXTPAPER Tab 10 additionally affords three completely different shade fashions that may alter colours on the display to be a diminished palette or make the whole lot utterly black and white.
The thought right here is that one among these three modes is perfect for various kinds of content material, however this pill has one large draw back: dithering. In a nutshell, TCL is utilizing the identical shade tech on its pill because it does on its in style TVs, which achieves deeper colours by flickering pixels between two colours. This makes every pixel seem as a shade that “doesn’t exist,” just like how your eyes will understand a non-existent shade when spinning a shade wheel.
TCL NXTPAPER tech is fantastic for every kind of content material however customers delicate to dithering ought to keep away from it till TCL affords the flexibility to disable shade dithering.
In my testing, I’ve discovered that this show works very effectively for any sort of process. Studying on TCL NXTPAPER know-how, particularly, may be very nice because of the attribute comfortable subtle mild. Altering shade palettes may help ease eye pressure for sure kinds of content material, though I discover I exploit the “shade paper” mode much less typically than the full-color “common mode” or the black & white-only “ink paper mode.”
The panel is vivid sufficient for indoor use however may be very troublesome to see outside, particularly in direct daylight. It additionally has reasonably poor viewing angles and is just perceivably brightest when it straight on.
This specific technology of NXTPAPER LCD does not refresh fairly as shortly as an OLED can, although, introducing some movement blur. That is significantly noticeable when scrolling by way of the OS or internet pages however I do not discover it as a lot when enjoying video games and by no means discover it whereas watching movies. This may be the only friendliest total tech if TCL might present customers the choice of disabling shade dithering.
TCL has gone out of its option to make LCD related once more with a wonderful matte end and a diffusion layer that creates a comfortable glow from the backlight. Totally different shade modes imply it is nice for any sort of content material and feels good when studying on for a very long time. Simply do not take it exterior as a result of it is not very simple to see within the solar.
OLED
OLED
OLED produces the deepest colours, highest distinction, and highest brightness of any fashionable show know-how. Whereas which means it is received the most effective picture high quality, it is also the harshest to have a look at for lengthy intervals of time, and using PWM dimming by many firms means the danger of eye injury is highest with this tech. It isn’t as power environment friendly as e-ink because it has to have a relentless present to energy, but it surely’s extra power environment friendly than LCD since particular person LEDs present the sunshine.
For the higher a part of the final decade, OLED shows have been slowly changing LCDs as a result of they appear higher and are extra power environment friendly. However the way in which some firms make their OLED shows — and even LED lights — are inflicting well being issues for plenty of individuals as a result of they flicker like fluorescent lights.
I’ve written about this subject many instances, so it is a topic very close to and pricey to my coronary heart. Whereas Samsung OLED panels typically function harsh flickering that makes me dizzy, offers me eye and complications, and typically makes me nauseous, OLED panels from different firms like LG, BOE, Visionox, and Sony (amongst others) solely flicker at low brightness and, even then, flicker at a far increased frequency than Samsung’s OLEDs.
The Honor MagicPad 2 I used for this experiment makes use of DC dimming know-how above 30% brightness and 4320Hz PWM dimming at decrease brightness ranges. In the meantime, Samsung’s greatest tablets use a paltry 240Hz PWM charge at all brightness ranges, which means there’s no escape from the flickering regardless of how vivid it will get.
OLED produces the most effective distinction ratio and deepest colours of the three completely different show applied sciences right here, in addition to the brightest total output, but it surely’s additionally the harshest sort of sunshine.
OLED produces the most effective distinction ratio and deepest colours of the three completely different show applied sciences right here, in addition to the brightest total output. Regardless of this, viewability in daylight is reasonably poor because the panel itself is tremendous shiny.
Honor makes use of true 10-bit show panels, so there’s no want for shade dithering because the TCL NXTPAPER Tab 10 has, however the direct mild from LED photons should still set off complications for essentially the most delicate customers.
Apparently sufficient, Honor has a sensible new know-how on this pill that works below the hood to assist forestall and even reverse myopia, in line with analysis. It is restricted to only some apps however guarantees some attention-grabbing potential if it will get rolled out extra extensively.
I’ve been utilizing this pill for the whole lot from watching motion pictures to working throughout Hurricane Helene and discover it to be extraordinarily comfy, however I don’t like utilizing OLEDs for studying. Concentrating on the harsher, direct mild of an OLED whereas studying simply doesn’t really feel good after lengthy intervals of time it doesn’t matter what’s finished behind the scenes.
Two winners
Whereas there’s no direct reply to which show sort is “greatest” total, one attribute impacts extra delicate customers than others: flicker. Many fashionable shows and lights flicker to attain completely different objectives, from shade accuracy to show brightness; flickering has a objective.
Nevertheless, firms that use flicker this fashion typically appear to overlook that human eyes and brains don’t at all times play good when strobing lights are concerned. Lack of flicker is the primary motive these three gadgets, specifically, are higher on your eyes.
Onyx’s e-ink know-how doesn’t flicker in any respect, but the occasional person will nonetheless really feel eye pressure from sure e-readers. This may be attributed to a number of potential elements, however the reality is that e-ink is essentially the most comfy sort of show for studying for the most important proportion of customers.
TCL’s NXTPAPER know-how has the potential to be the only greatest total know-how, however TCL wants to supply delicate customers the choice to disable dithering utterly. If that may be finished, the comfortable, pleasant DC-dimmed mild from any TCL NXTPAPER system will likely be a simple advice for anybody who desires an excellent pill to learn on, watch motion pictures on, and even work from.
OLED has the most important potential to inflict hurt due to its harsher direct mild, so use e-readers when doable for every day studying. TCL NXTPAPER has nice potential but it surely’s sometimes discovered on underpowered gadgets.
OLED has the most important potential to inflict hurt due to its harsher direct mild. For the reason that particular person pixels on an OLED panel emit mild, you’re trying straight at an LED once you view content material on an OLED as an alternative of at a subtle mild as with different show sorts.
There are numerous ways in which firms can use diffusion layers or present higher dimming choices to assist negate the unfavorable results of OLEDs. Samsung put an exquisite anti-glare layer on the Galaxy S24 Extremely, for example. However the know-how feels a bit just like the outdated Icarus story: fly too near the solar and also you’ll most likely get burned.
I’ve discovered that e-readers just like the Onyx Boox Tab Extremely are greatest for studying books or manga. Once I wish to watch a video or play a sport, the Honor MagicPad 2 is my go-to answer because of Honor’s use of DC dimming, an unbelievably good set of digital encompass sound audio system, and a strong processor.
I might love to make use of TCL’s NXTPAPER tech extra sooner or later however the firm’s use of low-power processors and shade dithering put it in an ungainly center floor which means it collects mud greater than it sees use.
