Over the previous few years, TCL’s NXTPAPER shows have develop into synonymous with eye care, however the firm’s subsequent evolution of the know-how is swapping out the prevailing LCD backpane for an OLED one, and that is making a number of folks nervous. I talked to TCL about these considerations, and the corporate shared unique solutions it hasn’t publicly disclosed relating to its upgraded tech, and I feel they are going to give some folks a really actual sigh of aid.

Android Central Labs is a weekly column dedicated to deep dives, experiments, and a targeted look into the tech you utilize. It covers telephones, tablets, and all the things in between.
I have been overlaying the unfavourable results of PWM dimming and temporal dithering for years, and now Samsung’s newest OLED trick is the most recent wave of know-how inflicting person discomfort and ache. It is a systemic drawback with a know-how that is designed completely to push the boundaries of show “high quality” whereas completely ignoring person consolation, however one firm is making an attempt to utterly rework OLED into one thing much better than now we have right now: TCL.

The subsequent evolution of NXTPAPER is switching from LCD to OLED this yr, and whereas it is bringing alongside a number of the acquainted tenets of OLED — wider colour gamut, extremely brightness, and quick response instances — TCL is making an attempt to do issues otherwise and, so far as I can inform, higher, all within the identify of eye security for you and me.

What’s unsuitable with OLED?

OLED has been one of the vital spectacular visible upgrades this aspect of HDTV and DVDs, however like every good factor, there are at all times tradeoffs. OLED is a self-emissive know-how, which implies every pixel emits its personal gentle fairly than counting on a backlight to cross by means of coloured filters, as in LCDs. And whereas this implies OLED has infinite distinction ratios and ultra-vibrant colours, it additionally means OLED will at all times flicker.
You may’t usually see the sparkle occurring as a result of it happens at a quicker price than your eyes may decide up, however our brains nonetheless discover it, and a few folks’s brains hate it. This flicker happens as a result of the pixel emits its personal gentle, so at any time when it has to alter colour, it turns off after which illuminates once more with the brand new colour. Each OLED producer handles this flicker otherwise, however analysis reveals that flickering at particular charges may also help forestall discomfort.

Sadly, a number of the world’s hottest smartphone firms — Samsung, most prominently — appear unwilling to alter their methodology to align with the science. I want I understood why, however it’s doubtless that their strategies work for sufficient folks, and the businesses merely do not wish to spend cash on new testing.
Fortunately, firms like TCL are paying consideration and appear to really care about our well being on this regard. In any case, it advantages an organization to maintain its customers wholesome to allow them to preserve shopping for new merchandise sooner or later. NXTPAPER OLED will use 3840Hz PWM dimming, a 10-15x improve over what Samsung, Google, and Apple use on their OLED telephones.
Analysis reveals that most individuals can’t understand any flicker in any respect past 3000Hz, so 3840Hz needs to be snug for the overwhelming majority of customers. Present NXTPAPER know-how makes use of an LCD backlight with a constant-driven present, that means it is actually a flicker-free gentle supply, however a really quick PWM price could be perceived equally usually.
Reflections, blue gentle, and the boogeyman

One of many core tenets of NXTPAPER is its paper-like high quality. It is within the identify, in any case, and the important thing behind it’s a distinctive chemical etching course of that TCL says offers it nano-level roughness. This texture is not simply on your fingers, although. It truly scatters gentle otherwise, softening the looks of the pixels and giving them a extra print-like look.
What to learn subsequent
The matte texture can be engineered to withstand fingerprints and smudges like no different show, too. I discovered this to be the case in each NXTPAPER machine I’ve reviewed, and it is solely gotten higher over time. This, mixed with the round polarizer and an extra blue gentle filter layer, makes NXTPAPER simpler to take a look at.

The large change with this new evolution of NXTPAPER is using OLED because the backend as a substitute of LCD. Which means we’ll preserve most of the fan-favorite options of NXTPAPER and get some great benefits of OLED distinction, brightness, and colour gamut.
As you may see from the comparability photos, OLED could make an enormous distinction in outside visibility when an anti-reflective layer is used. That, mixed with the matte-textured floor and circularly polarized gentle, ought to make NXTPAPER OLED really feel like the last word model of many individuals’s favourite show tech.

Except for outside visibility, NXTPAPER OLED also needs to deal with two color-related challenges in trendy shows. First, the shows are 10-bit, which ought to assist keep away from temporal dithering to artificially improve colour gamut. Current NXTPAPER shows use dithering in some conditions, which could be as uncomfortable as PWM dimming for some customers.
Second, it additional reduces blue gentle output. Blue gentle has been the show boogeyman for a very long time, and whereas all smartphones have some type of blue-light blocking, some firms implement it higher than others. NXTPAPER has at all times had a hardware-level blue-light-blocking filter, however NXTPAPER OLED additional reduces blue-light emission to 2.9% (down from 3.41% on NXTPAPER 4.0).
Not like different firms’ blue gentle discount strategies, TCL’s will not make your display all yellow and funky wanting. As an alternative of simply turning blue gentle off, TCL’s blue gentle filter shifts the blue output to the 457-462.5mm bands, which match snuggly inside the wholesome blue gentle vary. Customary OLEDs could emit blue gentle between the 400-455mm vary, which is taken into account dangerous.

Thus far, each main NXTPAPER improve has featured a brand new model quantity. TCL’s newest telephones, just like the NXTPAPER 70 Professional, characteristic a NXTPAPER 4.0 show, however TCL tells me it is planning on stepping away from model numbers from right here on out. The subsequent NXTPAPER telephones will simply launch with a NXTPAPER OLED show, and TCL thinks this can make issues clearer for everybody.
We do not but know which telephone or pill the NXTPAPER OLED will debut on, however we’ll doubtless see one thing by the yr’s finish. My greatest guess is that IFA Berlin in September shall be the place that telephone debuts, and that is a good time to unveil one thing as cutting-edge and groundbreaking as I surmise NXTPAPER OLED shall be.
It is laborious to imagine a $199 telephone nonetheless exists in 2026, however TCL has accomplished it but once more and made one thing that is not solely an incredible worth, but additionally seems to be and appears like one thing twice the worth, particularly with NXTPAPER 4.0 show know-how.
