iPhone X = diamond matrix pentile

[tipoo]

It’s a diamond but Apple’s doing a lot of stuff no other vendor has done with OLED before. Waiting to hit it with my loupe. https://t.co/TUESjuMFAA

Rene suggests there's more Apple has done here, but on further digging it sounds like he's backing off of any major OLED customizations and more talking about their general good calibration


Samsung OLED is Samsung OLED But there’s tons Apple can do, and did do, to make the X display.

Presented as it is for whatever it's worth. As a reminder, a diamond matrix pentile screen means that of the iPhone X's 450PPI, the red and blue colour channels actually have 2/3rds of that, ending up at resolving power closer to the base 8, rather than 400PPI Plus. The green channel, where people can see more detail with our eyeballs, does have the advertised resolution. Pentile also has nonlinear arrangement problems.


Since the diamond matrix is beyond question, I think we'll see that the Plus, not the X, is still the sharpest iPhone screen around, though there's obvious OLED benefits to contrast ratio.


Personally I'm on an iPhone 7 and I can easily see that things aren't perfectly sharp in any fine text or icon with a curve, even every homescreen icon, so 2 out of 3 channels having the resolving power of the 6-8 rather than the Pluses is a bit of a letdown. So in end sharpness, it'll be a bit above the base iPhone, but closer to that and still below the Plus which is noticeably better than the base.

So why wasn't anyone complaining with the Note 8? Well, that has a 520ppi screen, that still lands it above the regular iPhone on its worst colour channels, while being well above on its best. So Pentile isn't inherantly bad, but pentile plus 450ppi is looking suspect so far.




Of course, when it launches, 99% of people will think it looks great. 99% of people don't seem to notice the jaggies on the base iPhone either. That's fine. Just putting this here for those who care.

I don't know about you, but I have a SE and "it needs more PPI" has never crossed my mind.

I think I'm in the 99%. What features am I supposed to be looking for in the images above? To me they both look the same and both look ok.

Same here lol.

I think the OP put the same two images, that or we need microscopic implants to get better than 20/20 vision!

These two images are exactly the same.

It’s the bionic vision folks who care. Contrast ratio is far more important.

You should disregard anything that Rene guy says. It is also a silly propaganda that Samsung has used Pentile arrangement in order to inflate resolution spec, and you should disregard such opinions with prejudice. The devil is in the detail and implementation. Not only Pentile arrangement has pros and cons in comparison to traditional subpixel arrangement in LCDs (see: so-called "Dual-Domain Pixels," guess what, Diamond Pentile arrangement has that characteristics built-in from its inception), but 720p in the Galaxy S8 (which you can set in the settings app) is not the same as the 720p in the Galaxy S3.

What matters is the final presentation, and thankfully Apple excels in that department. Apple has a lot hanging around the iPhone X's success (so does Samsung, ironically), and I have no doubt the iPhone X's display will be nothing short of spectacular.

That does seem to be exactly what Samsung has done with Pentile arrangement. You really do need to multiply the PPI x 2/3 to get what the effective PPI is. For a while Samsung had Super AMOLED Plus, that had full RGB stripe. But I guess marketing 450 PPI SAMOLED was easier than marketing 300 PPI SAMOLED Plus. Bigger numbers are easier to market on the spec sheet.

I have a Samsung Tablet with 360 PPI LCD and my friend has the newer model with 360 PPI Pentile OLED.

Comparing them, my LCD is smooth and pixel free, and the 360 PPI Pentile OLED has obvious jaggies/pixelation.

iPhone X won't be the sharpest iPhone, it will be closer to the base iPhone in effective PPI. But even the base iPhone is sharp enough for most people.

Edit: never mind.

 

[Elixer]

These two images are exactly the same.

Yup, there is no pixel difference between them.

[pakotlar]

Very strange debate. Of course they're the same, they're clearly duplicates, i.e both have a earpiece/camera cutout, i.e both are iPhone X's...

The OP just made a mistake and posted the image twice, no need to spend any time comparing them. He's just showing the diamond pentile matrix using a macro shot, and a zoomed out regular shot to give context.

I think one must compare for themselves. As that is the only way said person can/will figure out what’s ‘Best!’ Not Consumer Reports, TechCrunch, Ars or Verge - GSM or DPR/AVS, Giz, or CNET, or the dude who’s post made it through Apple News’ filters and had his/her review posted. OLED Pentile doesn’t suck. But nor does Apple and their incredible Advancements made to Their LED/IPS LCD panels, backlights and the interactive ‘force’ touch’. Other than contrast/black level, Apple’s displays were as good or better each generation. In all other aspects; color, gamma, saturation and accuracy... but public demanding the blackness is s silly!
Not the sweet colors but the black on a phone is a device you’ll nearly never watch a movie ...EVER in a dark, blacked out room. The HDR & supposed brightness levels are curious to me. Not the BS about the green to blue to red pixel ratios. Don’t our eyes see one better than the other anyway?
I’m an owner of the 7+ and won’t be buying the “X”. Nor the 8. I’ll wait a year

 

[#12!]

BTW, I know AT is slow when publishing their full on iPhone reviews but it’s been some time for the 8 and we’ve seen nothing. Zero. Zilch. Pixel 2, same.
Kinda a shame as I could GAS about PSUs, keyboards and the latest motherboard of Intel or AMD’s flavor of the week

S8 has the best display this year by far. Not only the screen but how they curved around the edge. Design is just beautiful.

Actually, no. The Note 8 is the best Android display when calibrated.
The iPhone X with true tone gives the best overall color and appearance of any device I've used. And I pretty much own all of them.
I do like the "clarity" of the Note 8 and subtle curve to edge. Hopefully, Samsung will use ambient light monitoring to tailor the white point of their displays to match ambient lighting as Apple does. It's a brilliant idea and just works.

IPhone X display right now sucks simply because so many current apps have stupid cut off black borders making the screen the same size as iPhone 7. I had used big android phones for years and on iPhone X, tiny display really destroy the experiences whenever I watch videos and play games on iPhone X. The apps arent using 100% of the display available. In fact, it bothers me so match, I am now returning the phone. Until developers sort out the display issues on the iPhone X, it can hardly be the best.
