Before I begin, I just want to start by pointing out that I have never really been an advocate of PenTile, at least not in the way it actually turned out (RGBG). However, I would have liked to have seen what true (prototype) PenTile display would have looked like.
You see, as the "Pent" in PenTile suggests, the original design for a PenTile display included five sub-pixels rather than the two that it currently sports today; two each for red and green, and one in the centre for blue. This would have been truly awesome to see in person, but as far as I know, no device actually does this; it's always the cheapo crappy RGBG sub-pixel arrangement instead.
So this brings me to the question of the topic: What ever happened to (true) PenTile? The kind that uses five sub-pixels instead of two (or the three of RGB).
Can anyone provide some insight here?

It's a very problematic matrix, more subpixels per pixel also means more power drain, and in the case of AMOLED's- a lot more power drain+degredation problem of the blue pixels.
In addition to that, it's not so easy to just stack up so many subpixels in one pixel, you'll have to lower the screen's resolution to make it possible.
Personally, i'm happy with RGB, and i think they found a really elegant solution for the blue pixel problem in the Note 2.
My dear friend, you need to ask this question to some screen expert or manufacturer
I personally don't know what's the point of your question? As we don't even have anything to compare with.
If you want to compare something, your reference is everything.

My name is Candice Elliott. I'm the CEO of Nouvoyance. I was the founder of Clairvoyante... and was the inventor of the original PenTile layout and algorithms.
The original layout has yet to gain traction due to the discomfort display design engineers felt with having to use diagonal edged subpixels. It also was "too early" in the sense that the original PenTile quincunx subpixel rendering allows the reconstruction of each logical pixel with only 1.25 subpixels per pixel (on average... more are used but are shared among logical pixels). Thus, the resolution of the system must be very high to be in the recommended range. We are only now entering that range of 400PPI+. Anything lower, and this layout will use too few subpixels and will have pattern visibility. Perhaps in the future, as resolutions continue to climb, the original PenTile will be chosen?
Another commenter, wrongly, suggested that PenTile increased the power drain... the opposite is true. PenTile lowers the power drain on LCD displays, but is exactly the same on OLED. In OLED, the reduction from 3 subpixels per logical pixel (on average and fixed) to 2 subpixels per logical pixel (on average) reduces the wasted black area between subpixels, allowing larger subpixels that may be driven at a lower current density for the same light output... slowing down the aging process of the OLED material, giving the display a longer useful lifetime.
I hope this answered your question?
This is the kind of answers that i was talking about (i didn't understand all the details) but i think it's better than arguing with ignorance.

Displaygeek, the original poster talked about pixels with 5 subpixels per pixel.
You do agree that having 5 subpixels per logical pixel will increase the power drain, especially on OLED screens, right? I never suggested otherwise.
There isn't an advantage to 5 pixels per sub-pixel as more smaller pixels use more power than fewer larger pixels. The idea behind pentile is to extract similar image quality from fewer sub-pixels reducing power, space between pixels and easing manufacture.
A great article on pentile and what its all about: http://www.nouvoyance.com/technology-oled.html

Finally got to play with an Atrix yesterday. Simply put, I was shocked at how terrible the qHD screen looked.
Banding was visible from arm length, edges are extremely jagged, colors (particularly green on black) look absolutely abysmal.
Personally, I would much rather have a traditional 800x480 panel than a 960x540 pentile panel. In a side by side comparison the screen on my SLCD Incredible is miles ahead. I guess Motorola was more interested in having numbers that looked good on paper than real world performance.

This WRGB subpixel arrangement goes a long way in explaining the issues I saw... Actually, If I'm looking at this correctly each pixel does NOT have 5 subpixels, but 4. Quadrile anyone?
Ditto! I thought I was going crazy, hearing everyone talk about how good they thought the screen looked....it looks horrible imo....
Via the XDA app for the HTC Inspire
Same here
I was horrified how bad the colors were. Just install angry birds and check the colors. It looks all washed out and dull. The same is the case with NFS shift installed.
The text in the browser does look sharp though, i have to admit. But overall pretty disappointing.
Samsung S2 , please give us some hope here in the US, and soon!
Really? The worst screen that I saw was the Nexus S SAMOLED with its unnatural exaggerated colors and the lack of sharpness..
Having owned (for a short bit) an iPhone 4, a Nexus One (for 11 months) and having played around with a Nexus S for a week, I gotta tell you I really like the Atrix screen. I will admit that viewing it from the side blows...but how often do you do that?

As far as I know I don't see people using cellphones sideways.
While I'll definitely agree that it's far from the best screen ever, I don't think it's nearly bad enough to justify the number of complaints people have about it. Is it because it's the easiest flaw to point out?
Is the side view bad? I can actually see things fairly clear almost to the point of having the screen at an angle that I can't actually see the screen itself. Reading text gets impossible a fair bit before that I guess. If the viewing angle is limited on this phone, then I guess I don't often test the limits of viewing angles on other screens lol.
I don't know about you guys but I like the screen...lol, you guys must have better eyes our higher standards

once again,
the biggest misconception of the atrix's screen is that its washed out. This is NOT TRUE. the screen is extremely neutral in colors. SLCD and SAMOLED all have extremely exaggerated colors and contrasts. Some people like it, some dont...its like arguing which is better..plasma or lcd.....
I'm pretty sure if you do some research almost all video enthusiasts would recommend plasma over LCD. But that's not only because of the colors but also the response rate differences.
SAMOLED has perfect blacks so of course the contrast will be higher (infinite) but the colors can also be tweaked to not be so saturated. So at least you have the option to change it, rather than having an unsaturated display that you can't increase.

Hi guys!
As you know EeePad Transformer has quite a capable screen, with excellent viewing angles and good response time.
I just wrote an application to ease screen measurements, Free on market and Open Source, named Screen Test Patterns
But you might ask why its color look desaturated despite its correct contrast ratio.
I measure mine at 593:1.
All this explains when looking at the measurement graphs.

Luminance
Click to expand...
Click to collapse
Target 2.2 Gamma is the white curve.
Almost every color are displayed brighter than it should, which results in washed out colors.
Red curve is also brighter than Green and Blue ones, that makes the colors looks a bit reddish.
At almost white there is some clipping, fortunately quite minor.
Gamma
Click to expand...
Click to collapse
Consequence of the luminance curve, the gamma curve is very far from following 2.2 reference line as it should.
Average on this screen is gamma 2, which explains by itself the washed out colors (even if it's not the only factor)
Near Black
Near white
Click to expand...
Click to collapse
Near black there is no clipping but the screen uses a common trick to increase the visual contrast, by lowering the luminance of the darkest values (its called black point compensation)
That's not pure 2.2 nor fits to the sRGB model, but it's a nice detail improving the visual result IMHO.
Near white thing's are not right, there is some clipping. Means values 252, 253, 254 and 255 gives the same output. Not terrible in its amount but never welcomed.
Now about colors:
RGB Levels (compared to 6500K)

Here is individual Red Green and Blue channels values compared to what they should be to get a 2.2 gamma response at D65 / 6500K which is the industry standard for content display (web, videos)
Color Temperature

Click to collapse
Color temperature is mostly between 7500K and 8000K, but that's just numbers.
The most important in this graph is its linearity.
As you can see the white balance shifts to blueish in low between 0 and 15% gray.
This is because the black point of this screen (which is not black obviously) has not the same color characteristics as the other grays.
This screen doesn't really shines in this area, but its the case of most LCDs so there's nothing to worry here.
Still, it explains why dark grays look a bit blue.
Saturation Lumiance
Click to expand...
Click to collapse
Saturation Luminance graph allows to detect artificial color boosting like by an image processing
This graph shows that the luminance of colors are fairly linear. Not perfect due to screen hardware limitations, but okay.
Only notable is Greens and Yellows which are often lighter than then should. Once again it reinforce the lack of color punch, especially since its the colors our eye is the most sensitive to.
Saturation Shifts
Click to expand...
Click to collapse
100% Saturation is pure Red/Green/Blue/Yellow/Cyan/Magenta
This graph shows how much saturated are colors which are not at 100% saturation level (every non primary or secondary colors)
This graph shows that Red and Green colors lack saturation the most.
Blue saturation is a bit higher than it should in general.
I must admit I have no explanation why Cyan saturation is measured so high. It may demonstrate the presence of some sort of processing, but probably I don't understand the graph well enough yet.
CIE Diagram
Click to expand...
Click to collapse
And here is finally the famous CIE Diagram.
The latest explanation for the dull color is here: you can see the gamut is a bit small compared to the reference sRGB behind.
A smaller gamut has for consequence less vibrant colors.
Blue is okay, still lacks some extend, but Red and Green extension is lacking, as perceived by naked eye.
The additional dots show the screen is not affected by any color conversion distortion.
Wow, nice analysis there! I'm planning on getting a Transformer this fall for light school work stuff for ultra portability and long battery life.

You're welcome.
Transformer Kernel has no trace of any drivers nor hardware capable of color correction.
It's not impossible Tegra2 display controller has a LUT but still unlikely as no Tegra2 device I saw offer "color vibrance" control or things like that integrated in their PC hardware and drivers.
At the contrary, Galaxy Tab 10.1 which is also Tegra2 adds another screen controller with a very advanced color correction engine (implementing even things like sharpening, noise reduction, dynamic contrast, chroma channels adjustments), not available in Transformer hardware.
Tegra2 is not especially documented.
Honeycomb is closed source (for a potential OpenGL engine)
So no not planned so far, it's just an analysis in order to better understand what/how/why, and have fun with the tool I just wrote.
Well written analysis. Although I don't have a transformer (maybe wait for newer generations?), I really appreciate your approach in the refinement of sound and visual on our android devices. Your measurements and analyses are some of the most, if not the most, detailed and informative ones that laymen like me will be able to obtain and comprehend. Thank you.
Great analysis.
Just a question: did you run the analysis on a B60 or B50?
In my experience, having owned the two, B50 has a very cold display, (as in your finding) while B60 is much warmer and pretty close to my calibrated monitor.

Oh really there are several screen revisions with different color characteristics? (only backlight or more profound?)
I'm not sure what you cakll B60 or B50. If it's about the serial number, mine is partially wiped from the bottom transparent sticker, but its seems its:
B40KAS057442 12
The screen on my device is a bit cool but looks pinkish despite what the T° in Kevlin would say.
I'm not totally confident in the temperature reading of my colorimeters BTW, in some conditions.
Please tell me all that you know about different screen revisions
Anyway it makes sense there are several screen revisions because my measurement don't match in terms of temperature DisplayMate ones.

Only just found this thread. Man, if accurate, that's seriously disappointing. Did you ever get any reply on Twitter from Nvidia re LUT info or documentation?
I'm no expert when it comes to displays, but reading about AMOLED screens and PenTile "technology" (namely PenTile RGBW), I would like to discuss another possible color matrix that, for one reason or another hasn't come to fruition.
As you may know, there is the traditional Red Green Blue layout, and then there's the PenTile layout:

}
And then there's Pentile RGBW which adds a white subpixel while maintaining a 2 subpixel per pixel matrix:
So then what about a pixel array with the best of worlds?:
Red Green Blue White (4 subpixels per pixel)
Pros (Speculation)
Brighter display
Longer lasting red, green and blue OLEDs (due to only 1 OLED subpixel needed to display whites [a frequently displayed color] instead of 3 which would inadvertently preserve battery life)
Crisper, sharper, and not as blurry (compared to regular PenTile method)
Cons
Higher manufacturing cost.
Processor/GPU would have to process a lot more subpixels, which may lead to higher battery usage and less responsiveness/lag
So I see 4 possible pros, and 3 possible cons.
I would love to hear others opinions on this.
Would be ok, but:
1. White diodes are made from 3 RGB diodes inside it. So not cheaper nor better batery life.
2. For example if you need just plain white screen you wouldn't get it because there will be large dark gaps between white diodes. You would get grey screen. So no brighter screen.
3. There are no problems with green and red diodes, only blue one has short life span.

I'm talking about a white or "clear" OLED though, not LED, it's already used in PenTile RGBW. Nevertheless, it would still cost more.

Hmm, that is a good point. I hadn't taken into account that the white OLED would only take up 25% of the pixel block rather than 33%, a substantial decrease of 8%.

An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds instead of semiconductor material like Aluminium gallium arsenide in LED. That is the difference. There are a lot of more LEDs like Polymer LED, Quantum dot LEDs and so on.
Meanwhile the physic of forming colors is the same despite what produces the light. There are two primary ways of producing high intensity white-light using LEDs. One is to use individual LEDs that emit three primary colors—red, green, and blue—and then mix all the colors to form white light. The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light

Yes, although there are OLEDs which can sustain 400 cd/m2 of luminance for over 198,000 hours for green OLEDs and 62,000 hours for blue OLEDs and there is no need more

i found this
A method of determining implied sample areas for each data point of each color in a source pixel data specified in a first sub-pixel format is used for sub-pixel rendering an image on a display specified in a second sub-pixel format. Each of the first and second sub-pixel formats comprises a plurality of colored sub-pixels. The method comprises determining a geometric center of each colored sub-pixel of the first format to define a sampling point; and defining each implied sample area by forming lines that are substantially equidistant between the sampling point of one colored sub-pixel and the sampling point of another neighboring same color colored sub-pixel. A similar technique may be used for determining resample areas for computing color values for rendering an image specified in a first sub-pixel format on a display substantially comprising a plurality of colored sub-pixels arranged in a second sub-pixel format.

Let's not talk about engadget. Their integrity and competence is zero. They are always at war with samsung. I can give you a big list of proofs, but the discussion will just go OT.
Plain and simple, pentile is nowhere as good as standard RGB. No matter how you try to twist it.
If you manage to notice the difference between pentile and rgb on a dpi of 440 (440 dots per inch!), you should call the guinness book of records, because it means your sight is above human.
96 dpi is the average 1080p computer monitor / TV
150 dpi is normal top quality print
300 dpi is the limit visible by the human eye
440 dpi is overkill... pentile or not pentile... irrelevant

Agreed. It's why I bought a One X over the SGS3. But since, starting with the N2, Samsung's moved away from it what's to be discussed? How bad the SGS3 and Galaxy Nexus were or how bad the SGS4 could have been? When GSMArena does their standardized testing we'll know how good the display is in color reproduction, brightness, and white balance. You can't measure anything on a trade show floor except whether a display looks good or doesn't.
Are people really complaining about pentile at 440 PPI? Are you ****ing kidding me? Drop the crack pipe and wake up.

Not quite sure what you're trying to say, are you saying that it was only the Note 2 that used a pentile display?
As far as I know, ALL of the Note phones have a pentile display of one form or another. Samsung have varied the shape/sizes of the pixels, but they're all pentile.
The only flagship that Samsung has made with an RGB striple AMOLED was the Galaxy S2 (I think).
The Note 2 had a pentile matrix but it was RGB. The Note 4 will have the same pentile matrix as the S5.

Thats what i expect it to be.
Has anyone heard anything about the brightness and 'quality' of the screen?
(G3 has a big resolution, but contrast, viewing angles and blacks are meh.)

In the videos it seems to be brighter than the Note 3.
And I had the Galaxy s5 prime with a Quad HD screen and it was fantastic, it had a bit better colors than my Note 3. Indeed in some points it was better than the normal Galaxy S5 which has one of the best screens in mobile market.
What if its pentile.... Would anyone notice it at over 500 ppi? Come on now. The S5 has one I'd the best displays ever in terms of everything and it is pentile.

RGB is not PenTile!! PenTile means that there are different pixels like red-green and blue-green, so for a white color we need 2 or more of these pixels. RGB allows every color in every pixel, because every pixel are the same and consists of all 3 needed colors (red, green, blue).

That's pentile, not RGB.
Pentile is an arrangement where each main pixel shares one or more sub-pixels, in this case the blue sub-pixel I believe.

No. It's an RGB layout called S-Stripe. The only difference is that the subpixels are differently aligned. Each pixel has its own 3 subpixels.

Seriously.. Can't believe that we still get these posts.
So Note II is still the only Note that is not PenTile?
The S2 i had for a long time also had an RGB matrix. Pentile / diamond don't have to be bad. At over 500 ppi really shouldn't matter anymore.
Hope its at least as goof as the S5 screen - brigthness, viewing angles..both was bad on the S3.
The only Note devices without PenTile are the Note 2 and the Note 3 Neo.
