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 every thing in between.
Eye well being has turn into more and more extra necessary as our world turns into crammed with screens. Most individuals have a look at a display screen now greater than at every other time of their lives, so it is sensible to discover a kind of show that is not going to trigger you hurt.
Nonetheless, not each display screen kind is created equal, making some units higher for particular duties than others. For this specific undertaking, 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 a different way, however all have the identical aim: 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 reveals that some sorts of shows may cause well being issues over time, together with migraines and eye issues. Fortunately, this identical analysis is pushing corporations 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 a different way and even shows mild fully in a different way.
E-ink shows
Greatest for studying. Made up of bodily spheres which might be magnetically charged and do not transfer between frames. Extraordinarily vitality environment friendly because it would not want fixed voltage to function and may keep on indefinitely with out energy. Watching movies and taking part in video games is not doable on older E Ink fashions, however some newer units, 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 best way different varieties of show tech are liable 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 reveals 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 e book or an image in a manga — the pigments are energized to create a selected stage of grey after which keep in place till moved once more.
Which means that E Ink shows are extraordinarily battery environment friendly since they solely require energy when drawing. LCDs and OLEDs require fixed voltage to function and preserve a picture on the display screen. Moreover, E Ink “accepts” mild equally to paper, so it’s extra viewable as ambient mild will increase. Studying on the seaside with an e-reader is a pleasure, whereas it’s almost inconceivable with an LCD or OLED.
E Ink “accepts” mild equally to paper, so it’s extra viewable as ambient mild will increase. Studying on the seaside with an e-reader is a pleasure, whereas it’s almost inconceivable with an LCD or OLED.
All trendy e-readers use an elective frontlight, which suggests they’re lit in a different way from an LCD or OLED when 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 scale 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 colour 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 inconceivable to look at 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 instances — but it surely’s not as good to view this sort of content material an on E Ink show as it’s an LCD or OLED.
Likewise, colour e-readers typically have a diminished colour palette in comparison with LCD or OLED, which means they’re solely superb for studying.
The Boox Palma 2 is the right 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 price quick sufficient to do extra than simply learn books.
NXTPAPER LCD
NXTPAPER LCD
TCL’s spin on LCD tech features a diffusion layer to melt the picture and a matte layer to scale back glare. It seems extra like paper however isn’t as “genuine” as E Ink. The backlight makes use of correct DC dimming, guaranteeing zero mild flicker, however TCL’s use of colour dithering means pixels flicker to artificially deepen the colours. NXTPAPER options three completely different colour modes, together with full colour and a excessive refresh price that is nice for movies and video games. It isn’t as energy-efficient as the opposite two show varieties as a result of the backlight would not have zone management.
TCL’s NXTPAPER expertise is a reasonably new riff on older LCD expertise. Like conventional LCDs, NXTPAPER makes use of a grid of tiny pink, inexperienced, and blue pixels illuminated by a separate backlight to show what you see. The most important 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 tough to see particular person pixels, even below a microscope, giving the sunshine a beautiful “comfortable” high quality that no different show tech has.
Moreover, TCL NXTPAPER backlights are fully 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 beautiful “comfortable” high quality that no different show tech has.
TCL says that is the Goldilocks show tech because it’s acquired a wider colour vary than E Ink however would not sport the tough look of an OLED. The TCL NXTPAPER Tab 10 additionally gives three completely different colour fashions that may alter colours on the display screen to be a diminished palette or make every thing fully black and white.
The concept right here is that considered one of these three modes is perfect for several types of content material, however this pill has one huge draw back: dithering. In a nutshell, TCL is utilizing the identical colour tech on its pill because it does on its standard TVs, which achieves deeper colours by flickering pixels between two colours. This makes every pixel seem as a colour that “doesn’t exist,” just like how your eyes will understand a non-existent colour when spinning a colour wheel.
TCL NXTPAPER tech is great for all types of content material however customers delicate to dithering ought to keep away from it till TCL gives the power to disable colour dithering.
In my testing, I’ve discovered that this show works very effectively for any type of job. Studying on TCL NXTPAPER expertise, particularly, may be very nice due to the attribute comfortable subtle mild. Altering colour palettes might help ease eye pressure for sure varieties of content material, though I discover I take advantage of the “colour 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 tough to see open air, particularly in direct daylight. It additionally has quite poor viewing angles and is simply perceivably brightest when taking a look at it straight on.
This specific era of NXTPAPER LCD would not refresh fairly as rapidly as an OLED can, although, introducing some movement blur. That is significantly noticeable when scrolling by means of the OS or net pages however I do not discover it as a lot when taking part in video games and by no means discover it whereas watching movies. This could be the only friendliest total tech if TCL may present customers the choice of disabling colour dithering.
TCL has gone out of its technique to make LCD related once more with a ravishing matte end and a diffusion layer that creates a comfortable glow from the backlight. Totally different colour modes imply it is nice for any type of content material and feels good when studying on for a very long time. Simply do not take it outdoors as a result of it isn’t very simple to see within the solar.
OLED
OLED
OLED produces the deepest colours, highest distinction, and highest brightness of any trendy show expertise. Whereas which means it is acquired the most effective picture high quality, it is also the harshest to have a look at for lengthy durations of time, and using PWM dimming by many corporations means the danger of eye injury is highest with this tech. It isn’t as vitality environment friendly as E Ink because it has to have a continuing present to energy, but it surely’s extra vitality 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 give the impression of being higher and are extra vitality environment friendly. However the best way some corporations make their OLED shows — and even LED lights — are inflicting well being issues for plenty of folks as a result of they flicker like fluorescent lights.
I’ve written about this subject many occasions, 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 generally makes me nauseous, OLED panels from different corporations 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 expertise above 30% brightness and 4320Hz PWM dimming at decrease brightness ranges. In the meantime, Samsung’s greatest tablets use a paltry 240Hz PWM price 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 kind 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 quite poor because the panel itself is tremendous shiny.
Honor makes use of true 10-bit show panels, so there’s no want for colour 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.
Curiously sufficient, Honor has a sensible new expertise on this pill that works below the hood to assist forestall and even reverse myopia, based on analysis. It is restricted to only some apps however guarantees some fascinating potential if it will get rolled out extra extensively.
I’ve been utilizing this pill for every thing 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 durations of time it doesn’t matter what’s accomplished behind the scenes.
Two winners
Whereas there’s no direct reply to which show kind is “greatest” total, one attribute impacts extra delicate customers than others: flicker. Many trendy shows and lights flicker to attain completely different targets, from colour accuracy to show brightness; flickering has a goal.
Nonetheless, corporations 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 cause these three units, particularly, are higher in your eyes.
Onyx’s E Ink expertise doesn’t flicker in any respect, but the occasional consumer 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 kind of show for studying for the most important proportion of customers.
TCL’s NXTPAPER expertise has the potential to be the only greatest total expertise, however TCL wants to supply delicate customers the choice to disable dithering fully. If that may be accomplished, the comfortable, pleasant DC-dimmed mild from any TCL NXTPAPER system might be a straightforward suggestion for anybody who desires an important 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 each day studying. TCL NXTPAPER has nice potential but it surely’s usually discovered on underpowered units.
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 wanting straight at an LED once you view content material on an OLED as a substitute of at a subtle mild as with different show varieties.
There are lots of ways in which corporations can use diffusion layers or present higher dimming choices to assist negate the destructive results of OLEDs. Samsung put an exquisite anti-glare layer on the Galaxy S24 Extremely, for example. However the expertise feels a bit just like the previous 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. After I wish to watch a video or play a recreation, the Honor MagicPad 2 is my go-to answer due to Honor’s use of DC dimming, an unbelievably good set of digital encompass sound audio system, and a strong processor.
I would love to make use of TCL’s NXTPAPER tech extra sooner or later however the firm’s use of low-power processors and colour dithering put it in a clumsy center floor which means it collects mud greater than it sees use.
