Pentile suffers from strange color tints on whites.

Hard time rendering shades of gray.

Strange artifacts in low-light conditions.

Ofc all noise is camouflaged by the high resolution.

I would trade for the S-LCD screen of the Rezound any-day,

the only problem with that screen is that it could use abit deeper blacks.
[Galaxy Note GT-N7000 General] Xaddict:
I think this is related to OLED and not Pentile.

The Note screen does seem bluish to me when seen from an angle.

I don't see problems with grey on the Note.

I have view gradients to test the 24bit resolution and if viewed in a 24bit app, 24bit images look fine, otherwise not, but this is not an intrinsic fault of the Note's screen, only of the low res images or apps.
[Galaxy Note GT-N7000 General] maxh:
I'm not going to go back through and quote people, but some people said some things that are downright incorrect. Pentile does NOT "increase the resolution." It does exactly the opposite, decreasing it. Pentile has half the red subpixels and half the blue subpixels that RGB does; that means overall, pentile only has 2/3 the pixel elements that an RGB screen has. You can't display more information with fewer pixel elements.

The unpleasant artifacts I notice on pentile screens are small text, lines, graphics, appear fuzzy and sometimes colored on the edges, and when I look at solid colors that use red and blue (i.e.just about everything but solid green) especially white, I get this screen door effect. It's almost like there's a bit of checkerboard pattern to the solid color rather than being uniform. Hold your phone closer to your face and look at a solid white area, especially try to find a solid white area that is next to a solid green area with the brightness turned up all the way and you'll really see what I'm talking about.

Pentile doesn't necessarily use less energy than RGB. There are fewer subpixels, but they're twice as large and put out twice as much light. Energy in = light out. So in theory, the energy should be exactly the same. Perhaps they've found some way to do pentile a little more efficiently on some phones, but it's not an overall rule at all.

Pentile is used because it allows them to make the blues twice as big. Since they had a problem with short life span on those, making them twice as big made them hardier, longer lived, and higher yields in the manufacturing process. That's the ONLY reason for pentile. You could say this allows manufacturers to build higher resolution displays than they otherwise would be capable of (since they're cheating and using larger blues than an RGB would have) but a 1280x800 pentile is NOT "higher resolution" than a 1280x800 RGB! According to definition, they're the exact same resolution, but in reality, the pentile is lower in resolution.

RGB is ALWAYS better than pentile as far as image quality. The reason the Note's screen looks better than the SGSII, even though the SGSII had RGB, is simply because it has a much higher resolution. The benefits from that outweigh the negatives of pentile.

Here's a pic I put together showing the differences, even though you can find the same thing elsewhere on the net:

Thanks for summing that up =) Can we go on now and accept Sammy's gone cheap on us?
[Galaxy Note GT-N7000 General] indie:
I really am not too bothered about what screen the phone uses as long as it looks good, i do think to me it looks fantastic. Lovely and bright and it displays a fantastic picture. If people dont like a particular screen a phone uses then they have the choice not to buy it. Some posts in here are very informative so in that respect thanks. However people that ***** about the phones screen (not necessarily in this thread) have the choice to return it and wait for the screen of their choice to come out.
[Galaxy Note GT-N7000 General] ChodTheWacko:
The general public isn't noticing these artifacts, which makes me think they made the right decision on this one. After all, the General public would definitely notice a higher battery drain. I won't pretend to know the technical details about why Pentile battery usage < RGB.

Probably - but it's not interesting if that's not how you generally use your phone.

I wish I could find the interview, but they interviewed a samsung executive who was quite candid about the whole thing. He said quite clearly that Amoled + is sharper than Pentile. But he said that they went Pentile because in terms of sharpness, Amoled is good enough (i.e. still fantastic) - production is better (i.e. it's cheaper to make) and uses less battery power.

And they are correct. I've watched/read many many reviews of the GNote. For the most part, they all rave about the Screen, complain about the price, and are happy with the battery.

It would have been a mistake to put AMOLED+ in, and have the reviews (still) rave about the Screen, be even more turned off by the price, and only be 'okay' with the battery. (perhaps even complaining about it, saying 'Luckily it has a huge battery, because otherwise you'd be toast)

The GNote is already a niche device - you want to widen its appeal as much as possible.

Don't get me wrong, I'm very happy with my Note, including the screen. Search my posts and you'll see me say that several times. I'm a long time pentile hater from the day I first powered on my nexus one and started wondering what was wrong with the screen. Yet I've said several times that the Note's so awesome and the screen otherwise so beautiful that I'm able to overlook the pentile layout.

However I'm not going to read people claiming that pentile is better than RGB without speaking up, because it's not.
[Galaxy Note GT-N7000 General] Sjael:
(This isn't meant to be a hostile response, I apologise if it comes across that way - it's absolutely not intended)

It doesn't directly, no. But you then go on to point out exactly how it enables much higher pixel densities - in an RGB layout each sub-pixel is the same size, so they need to make the blue sub-pixel at a viable size (as you said,) then make green and red sub-pixels that are the same size again.

On a PenTile screen, they can print the blue sub-pixel at it's required size, but the green component can be much smaller - and as a result, you can fit more pixels into the same space. If you compare the Galaxy Nexus's 316ppi PenTile screen to the S2's 216ppi RGB screen, you'll find that the blue and red sub-pixels are actually of a comparable width.

Sure RGBRGB is technically superior to RGBG in terms of image quality, but after a certain pixel-density:distance ratio, it just doesn't matter anymore, and allows for a greater pixel density regardless of display technology.

As a point of curiosity (I know you gave this first point, I'm just elaborating,) resolution is a measure of the number of horizontal or vertical alternating black and white lines a display can produce while maintaining a certain level of contrast. PenTile screens actually are their advertised resolution. However low-density RGBG will lose some detail in reds, but greens are still fine, and the human eye can't see enough detail in blue to tell a difference there. That's in general though - obviously there are biological differences in people, and that is where the legitimate complaints come from - not from holding a phone 3 inches from your face. :D

As for whether RGB or PenTile is better - consider that the Galaxy Nexus's 4.65" screen could fit either 1280x720 RG/BG pixels, or 960x540 RGB pixels, and it's too dense to be able to tell the difference in sub-pixel arrangement. I think PenTile actually is better in that case.

small dots and big dots

okay so everyone is forgetting that not so long ago printers used to print using

only one size dot of ink. well the picture from same size dots looked grainy. so the print people came up with different size dots of ink to make the pictures look

amazing. i look at the pentile displays the same way. in comparison the

screens on rgb screens look blocky to me and those on pentile look smoother and

less grainy. iphone just shrank the dots to where the human eye can't detect

them. but i believe to acheive the same thing on a larger screen isn't very

pratical. that's where different size pixels will make images appear smooth.
[Galaxy Note GT-N7000 General] foxmeister:
Some great info that dispels some pentile myths can be found here - http://pentileblog.com/uncategorized/pentile-for-720-hd-oled-smartphones/.

Put simply, a lot of the criticisms of pentile displays are only relevant to particular implementations, and not necessarily to the technology.

I looked at the Note screen under a loupe and I could see a serrated edge along the top of white text on a black bacground. If I looked at it normally I couldn't tell. In this case the pentile doesn't bug me.

What DOES bug me is the low color depth that the Note displays. It is odd as it is inconsistant. If I look at photos it is fine. Some apps though look like the color depth is drastically reduced. Two apps to test are Angry birds Rio, and Google Sky. In AB look at the sky and clouds on the title screen, the shades all blend smooth on other devices (checked on an Infuse). On the Note there is severe color loss and much banding evident. Same with google sky There are these sky gradients, smoother on other OLED screens like the Infuse, much more bandy on the Note. I don't know why on some things like photos the note looks fine, but in many apps color loss and banding is evident. Maybe it is some weird incompatibility of the apps? Maybe they mis-read the screen capability and drop to low color mode? I don't know but it is weird and bothers me much more than the pentile matrix.
[Galaxy Note GT-N7000 General] Techvir:
My knowlege is zero about the ongoing discussion. However one question. Does selecting a pentile screen has something to do with the pen input ?
[Galaxy Note GT-N7000 General] Sjael:
Nope, that's just a coincidence specific to the Galaxy Note. :)

The original pentile arrangement had 5 elements, which gave it the pent- part.
[Galaxy Note GT-N7000 General] Xaddict:
The use of PenTile technology for OLED has been to achieve high resolution for OLED, plain and simple.

This misinformation seems to be the main reason some people have against pentile.

But you CAN display the same information with fewer SUB pixels.

And you can display the same information and use less power, believe it or not.

You obviously didn't read any of the information linked on the first post.

[Galaxy Note GT-N7000 General] Xaddict:
No.

You have a high resolution, high contrast display that uses less power.
[Galaxy Note GT-N7000 General] Xaddict:
This bugged me too and I was not happy about contouring(banding) in gradients as I had read before buying the Note that the display was 24bit(Millions of colours).

I researched it and found that the Note IS 24bit, but when you view 16bit images/videos or use a 16bit only capable app, like the stock photo viewer, or the stock browser, gradients will show banding.

You can use the gradient on this website to test this: The Lagom LCD monitor test pages
[Galaxy Note GT-N7000 General] LordManhattan:
Very interesting reading :) Thanks
[Galaxy Note GT-N7000 General] maxh:
I did read the article, with information largely from Nouvoyance, the company responsible for pentile technology...

It's not misinformation. If you meant pentile opens up the capability for manufacturers to produce higher resolution OLED screens, then I apologize for the misunderstanding; I took what you said about it increasing the resolution to mean between two otherwise equal screens, the one with pentile would have a higher effective resolution than RGB. That's untrue.

The only way a pentile layout with fewer subpixels could display the same amount or more information than the sage screen with RGB is through, in effect, image compression. Nouvoyance even said something along those lines. In an abstract way kind of like how an image saved as a jpg can take up much less space than a raw bitmap. Compression allows for a reasonable interpretation of the image to be stored in less space, but information IS lost. That's why jpg compression is considered "lossy."

Pentile is the same way. It can give a reasonable rendition of your image, but information is lost translating it to be displayed on the fewer subpixels. This is the source of some of the artifacts.

That article and your listed benefits read like a brochure targeting manufacturers. As a customer, I want the best image quality possible, first and foremost. RGB delivers that. The manufacturer is the one that needs to think about making it possible to manufacture, for a reasonable price, and without other drawbacks like power drain; not me. And even Samsung recognizes that RGB is a more desirable layout, as far as they eyes are concerned. RGB layouts are labeled super AMOLED "plus", while pentile lacks the plus.

Until my pentile screen doesn't look like a fishnet is draped over solid colors, (blue included even though the article suggests people are less sensitive to blue so should not have that effect) and small, unzoomed text doesn't have fuzzy edges, I'll prefer RGB.

[Galaxy Note GT-N7000 General] :
FUD?

LOL! Have you seen a Note in real life? There's no "fishnet" over any colors. I guess your apprehensions were correct with lower res pentile screens like on the Nexus One, but on the Note the resolution removes all those side effects. Pentile has hit a sweet spot there. All I can say is that I'm 110% certain that the Galaxy Note has the best screen available on ANY phone today and that's good enough for me.

Anyway, next year Samsung is going to announce galaxy tab 7.7, which has a super AMOLED Plus screen.
[Galaxy Note GT-N7000 General] Patanjali:
Basically, if at the normal viewing distance, you cannot discern any technology artifacts (that is, they are smaller than your retina's resolving capability), then it is irrelevant what technology is actually used to make the display.

Other than that consideration, the arguments about which display technology is an academic argument which has no place in the buying criteria for a device.

In other words, if you cannot tell the difference just by looking at it at normal viewing distance, you are just a wanker trying to get people upset for no good reason than being a pompous asshole.

From what I have read, pentile displays worse at low resolutions, but at 'retina' resolutions, it is irrelevant.

I could only notice differences between the Note and a 4s when held up close with my best glasses or a magifying glass, but not at normal operating distances.

Nuff said!
[Galaxy Note GT-N7000 General] rlaw:
I'll probably trade in this Note if the next one has a non-pentile screen.

Call me an outlier if you wish, but I can absolutely tell that this is a pentile screen. I noticed as soon as I first turned the screen on.

I love my Note but I have no disillusions about the screen. It could absolutely be better.

And no, I don't have to view it super close to tell. Between 12-18" is close enough. There's just something.. off about the screen. Especially evident with text.

It's just not very sharp, at all!
[Galaxy Note GT-N7000 General] Alexanderbooth:
Basically its like the age old argument, vinyl is better than cd! But the fact is hardly anyone can tell the difference. I love the screen on my note, not really bothered if it has to share sub pixels

As a regular reference text PDF ereader I can practically say that certain document texts are illegible or fuzzy at the same zoom level on a note vs an SLCD screen of my iphone 4 or HTC Sensation.
[Galaxy Note GT-N7000 General] maxh:
I'm the biggest pentile hater in the world, but you can fit 2 full iphone screens inside the borders of one Note screen. So zoom out a tad. :p

When I used my Nexus One, I noticed the pentile layout every time I looked at the screen. With my Note, I don't notice any subpixel artifacts at all unless I bring it close and look for them. Note >> iphone (but I still want RGB subpixel layout on Note2!)
[Galaxy Note GT-N7000 General] rlaw:
If the SGS3 OLED rings true, the next 720p screen will utilize a type of in-between rgb/pentile. There will still be an extra green subpixel. It will be sharper than pentile but still not as sharp as LCD.

Ho hum.

More info on this:

Source: http://mobilesyrup.com/2012/04/12/rumour-oled-association-says-samsung-galaxy-s-iii-to-have-a-4-6-inch-super-amoled-hd-plus-release-in-may/

http://oled-a.org/news_details.cfm?ID=760

Impressively, the rumored specs for the SGS3 give a 4.6" screen at 319ppi, which is just a hair under the iPhone's 326ppi but at a full inch+ diagonally.

Presumably we can expect the Note 2 to have this same type of screen-subpixel arrangement (but larger of course).

While impressive, and while I can detect the pentile matrix of my Note's screen, this news doesn't struck me as a "must" upgrade. I probably, definitely would for a full RGB arrangement, though.

Samsung's next Exynos iteration is also expected to simply be a quadcore upgrade of their existing A9 instruction set basis. Performance will still pale in comparison to chipsets utilizing A15 instruction set.

Of course, these are all still rumors so far.

Still, it does seem like I may just wait the year and a half for the Note 3. =)

Oh la la... pentile screens...

What can I say? Bad implemented pentile tech, it's the worst thing that can happen to a phone.

As an user of the droid 3, the screen ruins all the fun. Some colours as green, arent represented as it should. And you can see pixels everywhere. A solid colours looks like it's just a bunch of giant pixels trying to compose it.

On the note, pentile is implemented pretty well. Some colours could have the kind of weird pixels around it. But text is sharp and solid colours looks pretty decent.

The only real noticeable problem, is the dark grey rendering mess. Not sure if it can be tuned or improved.

Both screen are years lights of distance. And both are pentile.

As much as I love the GNotes screen I hate reading text. The white background has a slight cream/yellow hue, but that's the only thing I don't like about that. I came from an atrix but surprisingly never had that problem :confused:
[Galaxy Note GT-N7000 General] Alexanderbooth:
how could it be better? you cant get 1280 x 800 super amoled plus screens yet, how could they put in a screen they haven't made yet. Instead they put in the best screen they had at the time, its like saying the processor in the note is **** they should have put a 5ghz quad core one in it.

I would sooner have a 1280 x 800 res screen than a super amoled plus screen at 800 x 480 like the s2. Bet if you stretched the s2 resolution to 5.3 inches it would look shockingly bad, and you like many others would have probably starting spouting they should have used a pentile screen to up the resolution to make it a nice screen!!
[Galaxy Note GT-N7000 General] rlaw:
Don't be dense, the screen could be better by not using a pentile subpixel arrangement, duh.

Anyone noticed how gradient banding is pretty much gone on the ICS roms?

I remember reading somewhere that it was a 'pentile' problem, but it mustn't be if it's gone in ICS. I would see it everywhere on GB.

[Galaxy Note GT-N7000 General] rlaw:
No one besides you said anything about using technology that wasn't yet viable.

Just because this is the best screen with available manufacturing processes at the time doesn't mean this is the best screen period or that it isn't without faults.

To achieve this resolution at this size required compromise, we're all aware of this.

Why are you so dense?
[Galaxy Note GT-N7000 General] Alexanderbooth:
You're just being dismissive though and insulting me doesn't help your arguement, your criticing samsung for the screen, when they had no choice. They and me also obviously made the choice that this screen is perfectly acceptable and works much better than any other screen around. It could be a better screen yes, but even a hd plus screen could be better also, that's the beauty of tech its always improving. The note 2 will probably have a hd plus screen but by tht time the next screen tech will be available are you going to then ***** that the hd plus screen isn't good enough either? If your that unhappy with the screen get rid of your note and get a phone that you are happy with the screen, its pretty simple really.
[Galaxy Note GT-N7000 General] rlaw:
Dude, this the last time I'll respond to you because it's obvious that you just want to pick a fight for who knows what reason.

I'm happy my phone, I love it. I'm not blind to its various faults, however. It is not a perfect product. And I am more than willing to admit that than blindly defend it.

This screen is not the screen to end all screens and despite its massive size and resolution, there are still other screens out there that hold advantages in certain categories.

I recommend this phone to anyone who asks about but I make sure to point its shortcomings and where the next iteration could stand to improve.

There. I'm done with you.

So. Dense.
