The Atrix's awesome pentile screen!!!

PenTile RGBW technology adds a white subpixel to the traditional red, blue, and green subpixels in a color display allowing a brighter display using less power.
The PenTile RGBW layout uses each red, green, blue and white subpixel to present high-resolution luminance information to the human eyes' red-sensing and green-sensing cone cells, while using the combined effect of all the color subpixels to present lower-resolution chroma (color) information to all three cone cell types.
Combined, this optimizes the match of display technology to the biological mechanisms of human vision. The layout uses one third fewer subpixels for the same resolution as the RGB Stripe (RGB-RGB) layout, in spite of having four color primaries instead of the conventional three, using subpixel rendering combined with metamer rendering. Metamer rendering optimizes the energy distribution between the white subpixel and the combined red, green, and blue subpixels: W <> RGB, to improve image sharpness.
The display driver chip has an RGB to RGBW color vector space converter and gamut mapping algorithm, followed by metamer and subpixel rendering algorithms. In order to maintain saturated color quality, to avoid simultaneous contrast error between saturated colors and peak white brightness, while simultaneously reducing backlight power requirements, the display backlight brightness is under control of the PenTile driver engine.
When the image is mostly desaturated colors, those near white or grey, the backlight brightness is significantly reduced, often to less than 50% peak, while the Liquid Crystal Display levels are increased to compensate.
When the image has very bright saturated colors, the backlight brightness is maintained at higher levels. Since most natural images and black on white text have few simultaneously bright and saturated colors, the average power of the PenTile RGBW panel is 50% less than a conventional RGB LCD.
Since the LCD backlight is the major power using component on many portable devices such as cell phones and personal media players, products that use the PenTile RGBW panel have appreciably longer battery life.
The PenTile RGBW also has an optional high brightness mode that doubles the brightness of the desaturated color image areas, such as black&white text, for improved outdoor view-ability.
The Motorola es400 and Motorola Atrix 4G cell phones use PenTile RGBW LCD displays.

Regardless of what the article says, I know what my eyes see. Pixelation of small-scale text, terrible washed out yellows, and super pixelated greens.

Not quite sure what the point of this thread is... all you did was copy and paste some info from wikipedia. I'm perfectly fine with the screen, though a lot of people seem upset. Those complaints seem to be slowing down at least. It's not the best screen, but it's perfectly fine to me for my phone. I'd be a bit more upset if all picture quality was messed up (both screen and via HDMI), but it looks perfectly fine on other screens.

i copied and pasted text that proves that this pentile argument is false. You put up with some slightly ok colors and get 50% more battery life.

Some of us have better vision than others.
I would gladly have paid more for anything that wasn't pentile. I try my best to ignore it, but it's so difficult when you can always see it.

..................

It might be a bit more power efficient but the yellows and oranges seriously look off and the greens like look a fly screen.
Also the pixel response rate is seriously bad, TONS of ghosting. This display really only works well with black text on a white background with not much animation.

That's because you're seeing something you knew about. If you didn't know it was a pentile screen you'd never see that stuff. Sitting my Atrix next to my iPhone 4 I can tell a difference, but not much of one.
I should mention I was in the Air Force and offered a pilot position, which isn't done unless your eye sight is damn-near perfect. I've had 40/20 vision my entire life and I'm a pretty good videophile. You see that stuff because you want to.

I compared the atrix to every other phone in a verizon store. Everything except the iphone 4 had a worse display.

If you read any of my posts in the main Pentile complaint thread, you'd know that I didn't even know the phone had a Pentile screen (or what that was for that matter) until after I got annoyed at the greens and yellows of the screen. It's ABSOLUTELY obvious that greens show jagged pixels, expecially when looking at thin greens (zoomed out text, lines, etc) and that yellows are more of a squash color. That was the first thing I noticed when zooming through some sites and playing Angry Birds (having played it on my iPod touch many times before). I then came on this site and read Anandtech's review and found out what a Pentile was.
If you can't tell the difference or shortcomings of a Pentile dispaly vs. a similarly dense display (i.e. the Retina) I can't point to anything else but denial. The screen is nice, but not that nice.
On an unrelated side note, I work in engineering for the modules that guide your fighter jets when you need to see without your eyes. I do wish I could take a ride in one though.

Atrix screen and HDMI sample videos
Last night I went to a concert and taped the show. The screen remained on for the entire 2 hours and still had 70% battery power left. If I were on my previous Captivate it would not have lasted 2 hours. It would seem the same people unhappy with the Atrix screen would be unhappy with the battery life if the Atrix had a different screen. I have posted this before: the Atrix screen is perfectly fine, even better than fine considering its efficiency. I have several hi res (720p) movies that look absolutely wonderful on the Atrix. Colors and resolution look beautiful. The colors do not have the super saturation of the Captivate, but still perfectly fine. Motorola should have provided some sample videos, but they didn't.
I was in the AT&T store playing around with the docks. There are 4 720p sample videos on the phone apparently only available thru HDMI. If someone could post those videos here so we can all have a look at them that may help quiet the screen concerns.

It's not so much pixelated, but pixel-less. Text is undeniably sharper on the Atrix than it was on the Captivate.

aside from the iphone 4 which ofcourse has a better screen..
why would i want to go with an atrix screen and not a super amoled screen if i can see the pixels on both screens. yet the super amoled has better blacks and better colors in general ?
mind you i have used all phones including the atrix " even though it was a short period of time "

I am happy with the screen. It is not perfect, but then it is a mobile phone.
If i want awesome colors and deep blacks I have a rockin' 54" plasma. If I want super clear high resolution fonts, I got a great monitor.
I will trade a perfect phone screen for better battery any day. And for me, this pentile display is damn near perfect.

Lol nice one or maybe he is hypnotizing himself that the Pentile display is acceptable because he doesn't want to go through the trouble of returning the dual core webtop phone LOL :-D
But seriously SUPER AMOLED screen has very vibrant color which I actually like but the battery life is bad for web browsing. I wish they have sepcial designed webpage viewer to create black background and white text for SUPER AMOLED screen to conserve battery life.
Finally, I think I've gotten used to the Pentile screen color. Its not really good bit at least its acceptable eventhough the color are distorted and not sure if software can solve the color issue.

So, everyone is complaining about the Atrix display? What about the cellphones dating back from the 1990's? I bet the display was pretty ****ty too. Oh wait, i dont see anyone complaining. Did any of you know about Pentile display back then? NO!?
Please spare us the comparison of what display is better etc..
Here is an idea. Why dont the rest of the ppl who complain about Pentile/SAMOLED etc..invent your own display? simple as that.
You dont like the display on the phone, DONT BUY IT! Stop whining about it.

iphone 4 screen displays better whites

Today I showed the screen of my galaxy s II to my iphone4 owning friend. We both loaded up bbc home page, and the white background on his phone looked much better than on my phone.
On my phone the white background looked cream in colour, where as his displayed as pure white.
Will this be able to be fixed with vodoo colour?

It can be helped with Voodoo color, but it can never look like an LCD based display since SAMOLED screens don't have the LED backlight in the back. And also, an iPhone 4's display has already been proven to be a bit blue tinted which makes whites look brighter when they're actually a slight shade of blue. I've spent a lot of time calibrating my Nexus S screen with Voodoo color and I can safely say the result is a more pleasant shade of white than my friend's iPhone 4. Also with Voodoo color I can boost the brightness higher than what the stock specifications permit so it's even a brighter white than the iPhone 4's if I want it to be, but it consumes a LOT of power.

the nature of LCD and OLED makes the colors differ here in America. It also makes the colours differ in England and most of its former colonies.
You can try setting the separate brightness setting in the browser settings to 100% (it is separate from general brightness setting in the phone settings).
I bet it would still have a different hue if you look at them side by side.
You can also try taking a friend with an iP4 that is a year old to a store that sells iP4 now, and compare how they look - you will probably see some difference there too, side by side.

He was saying to me, "oh your screen tech hasn't evolved yet, you cant display proper white", haha, "my text is so much sharper than yours".
It was true about the text, my heart sank when I compared BBC homepage in portrait mode. His text looked MUCH sharper than mines. But then he has got a much higher resolution.
I really did feel humiliated, I just want nice pure white like the iphone4 has. I know I don't have a backlight.

that is a freaking picture of some fabric, right??? because I got scared thinking my laptop LCD is showing banding on cream color.

Haha... I guess the only difference between boys and men are the price of their toys huh?
If you want to humiliate him, ask him to show you a black image. Then laugh at how much light leakage he has. Then play a high quality youtube clip like a movie trailer with some action scenes, then laugh at how slow his pixel response is (ghosting). Also while you're trying to play a high quality youtube clip... remind him that he needs to be on wifi in order to do it because he only gets low quality over 3G =)
Trust me I'd take the SAMOLED over an LCD display any day. Same reason I have a plasma TV and not an LCD/LED one.

They are phasing out plasmas because they are more expensive, eat more power , are harder to make, and can't compete with LCDs in price.
Real video buffs still prefer Plasma for its true blacks and great refresh rates.

I'm not gonna let this get into a TV debate but it's well known videophiles and avid cinema/sports watchers will always choose a plasma TV over an LCD because of the purer blacks and insanely faster pixel response (no ghosting like an LCD/LED). The mere fact that LCD/LED TVs even have to QUOTE a pixel response time indicates an inferiority.
And this also carries through to phones. If you don't believe me, try it. Pick up any HTC phone and compare it to any Galaxy phone. Go to a black menu with white text... perhaps the settings menu and scroll up and down. You'll notice MASSIVE text ghosting on the HTC LCD screens but none on the SAMOLED screen. Please, don't come back claiming things you haven't tested yourself with no facts to back it up.

Real buffs prefer high quality LED panels, plasma simply can't compete with the definition even if fast moving imagery is sometimes better. And I know this as someone who has owned high quality sets of every type.
Plasma's days were numbered as soon as it's monopoly on extra large panels ceased to exist thanks to LCD and then LED technology allowing 42" and above panels to be financially and technically viable with no loss of quality.
Still, we can agree to differ on all that if you wish.

I fail to see where the comparison between SAMOLED and LCD is relevant to a comparison between LCD/LED and plasma.
Oh, and I have tested myself.

What do you mean with "pure white"? To me it sounds like iphone has colder color temperature, that is not better, just different. In fact that would give less natural colors.
Try to change color temperature on your pc monitor to understand what I mean, a warm temperature of 6500K is more creamish than a cold temperature of let's say 9000K.

I hope you do realize LED is just another type of backlight for same LCD screen, and it not always makes that same LCD produce truer blacks, and it does not do a thing to refresh rates.

Obviously, I'm well aware of the technicalities of all current TV technology or I wouldn't be entering a debate about it.
Anyway, agree to differ and move on, as said derailing this thread is pointless.

Ask him to play a flash video from the browser And it is true the iphone's display is fairly impressive but I prefer the bright colors, larger size, and better power consumption of the SAMOLED+

Are you aware that the GS2 screen has 2 different brightness settings? It has the normal brightness, but lower down the menu it has a setting 'Auto adjust screen power' This actually dulls whites when there is a lot of white on the screen to reduce power use. If you untick it the screen is a lot more pure white.
Oh and on the subject of TV screens plasmas are getting a boost from 3D. 3D plasmas are much better than LED/LCD because of their reaction times. Much much less ghosting and as a result deeper 3D effect. A full HD plasma is still the best screen there is right now. Much less harsh than an LCD, better blacks, more realistic colours and less intense whites.

Who cares about which screen displaying bbc has better white. This baby has everything, 1080p, bluetooth 3.0, wireless n, hspa+, dual core, android (!), better battery and I think the samoled+ can display colours much better. Also no gay itunes and you do not need to jailbreak your iPhone (which makes the iPhone instable and ****) to just get freedom
Edit: forget about these things
4.3" screen, 9mm thick, 116g, micro sd slot and more.. seriously that phone rapes the iPhone

funny that you fall for that
put his iphone in the sun and say "whats white good for if you can't see anything?"
they're different techs. besides, true white is subjective. then theres like 150 other reasons why the SGS2 is technically better, and why the iphone5 will actually be very similar to the SGS2.

I can confirm this "cream" or, as I would put it, "yellow" tint to the screen and whites in particular. It's not right - I consider it a fault. My old (now current) SGS has the most perfect, even whites I've ever seen on a phone - even beating thr iPhone 4 in my opinion.
The SGSII is horribly bad quality as far as I'm concerned. I see nothing in SAMOLED+ that improved over SAMOLED. It's actually more grainy, too saturated, viewing angles - bizarrely are off, and blurs slightly when scrolling. What the hell is up with Samsung?

Issues with Display (Colors)

Does anyone know if Motorola plan on releasing something to change the gamma/saturation/contrast on the Xoom? I love everything about it and own one, except for the fact everything looks washed out. I assume this would be a easy fix for someone to implement something similar to a monitor where you can pick the color temp of the device 5700k 9700k ect.
This is becomming a deal breaker to me as I watch a lot of videos and the colors look horrible.

It is definitely on the cool side, but far from horrible. With all the customization offered by android you would think screen preferences would be available.

I use an app called Color Filter Settings".

I measured my WiFi-only XOOM with a GretagMacbeth Eye One Colorimeter, and its color performance and gamma curves were actually pretty stellar. I also used these test images to visually inspect the picture. Using the LCD test images, the only faults I could find are the less than perfect viewing angles and (very) slow pixel response times typical of VA panels.
For reference, I am a photographer and have several D6500K calibrated monitors (2x Dell 2408 WFP (b) and 1x Dell FPW 2405).

yeah, just eyeballing it and i thought the xoom was pretty good. it hold shadows well, but washes out in the highlights. the transformer is waaaay too cool. some whites and light blues come out looking purple. it doesn't hold shadows as well but highlights are better.
to me a warmer color looks more natural.
i do image editing/color matching in print.

The Xoom's screen is sub-par. Why do people on this forum alway's try to make someone who draw's a problem about the Xoom feel like they are less intelligent? Every intelligent person know's the Xoom's screen is washed out... How about reading the reviews ? One of the only negative's about the Xoom is it's screen and video capabilities. As why this thing barely sells.
Put it next to the iPad2 or Playbook and see how crappy the Xoom's screen is. No need to do "specials tests" blah blah it's easy to see. It's a BIG difference. What you expect tho ? The Xoom has alot more going for it so i'm not surprised they didn't get the best panel.
LONG LIVE THE XOOM THO !!

Not quite... The reason other displays look "better" to your eyes is that they are calibrated to look appealing rather than accurate.
Do yourself a favor and take a look at a Motorola Droid. Now look at a Samsung Nexus S. Your tastes will probably favor the Nexus S's screen. However, I would far prefer the screen on the Droid, as it is much more accurate and better calibrated.
There's no right or wrong screen here, as it's all user preference. The Droid, like the XOOM, has an extremely well calibrated, accurate screen. They aren't shockingly vibrant nor does they have incredibly high contrast. However, if they were incredibly vibrant and had really high contrast, other users (such as myself) would call the image gaudy.
Bottom line is that if the XOOM looks wrong to you, you're not used to looking at well calibrated screens.
(Note: I'm only speaking from my own personal WiFi-only XOOM. I am not aware of how much variability there is screen-to-screen on XOOMs.)

Hmm... That's strange. If you click the LCD Image tests I have linked earlier, specifically the white saturation, how does your XOOM do? Mine reveals 254 as well as any of my calibrated monitors. I'm wondering if this means that there is a good deal of screen variability.

I thought the LCD is AUO or SHP also matters. Mine is SHP which stands for "Sharp", problem is potential light leak. Correct me if I am wrong though.
Also, I hand my left hand carring ipad 2 and right hand carring Xoom (because right hand is my stronger hand) last weekend,
Screen-wise, if you turn xoom brightness higher, those two screens looks same to me.
Btw, ipad 2 IPS screens also has infinite finger-prints too...
Only challenge appeared to me when I put these two head-to-head compare, was apps.
We definitely need more sexy slick powerful Honeycomb apps!

Ah! I had forgotten about the two different screens. For reference, I have the AU Optronics screen.

Screen?

Coming from a Galaxy Nexus, my main concern is - How are the black levels gonna be? I absolutely LOVE SuperAMOLED - Mainly, the blacks - I LOVE THEM and I'm sure many other users do. I don't know if the LG's black levels are gonna be as good or better? Does anything know that?
I have a choice to jump from the Gnex to the Nex4 but if the screen's black levels aren't as good - I probably won't.
What's your opinion about the screen?

Go look at a One X, it'll be similar to that (which is SO much better than the GNex screen - IPS ftw!!)

Yeah but the black levels

It definitely won't be as good. The question is, will it be good enough.
The apparent high end screen on my laptop has a rubbish black level. So I'm also hoping the Nexus 10 has good blacks, so I can use that for media instead.

But did you look at the Htc One X screen, or atleast youtube it?

Yeah I've used the One X a lot of times and I'm not impressed at all. The color reproduction is good but the black levels don't amaze me, at all. I feel that my nexus' screen is much better than the OneX (Just my opinion, don't pounce on me)

With AMOLED, the blacks are black because the led's are switched off, it doesn't try make the colour "Black".
LCD screens do not do this. So blacks will be grey, but colours and viewing angles WILL be better. Another thing, AMOLED is a battery drain with anything other than the colour black.

OLED screens will always have darker blacks than LCDs. That's just due to the nature of how each type of screen technology works.

I very much know how AMOLED works. Guess the blacks won't be that good on the Nex4. :| Hard decision to make now :\

But your question meant that you don't. If you know this, then you should know about LCD too...

They will probably be as good as any IPS LCD on the market. LG makes very good smartphone displays, including iPhone 4/4S/5 displays.

Just look at the present ips screen on the LG top model phones, i'm sure the nexus 4 will be similar.

The blacks will not be the same as others mentioned but it's a tradeoff. Super amoleds have good contrast and blacks but the ips lcd's I've seen had better color accuracy and sharper images. I like amoleds but the whites and other colors aren't that good and the brightness isn't high enough for my taste. I look forward to seeing the n4 up close

I have mixed feelings as well regarding the screen of the new Nexus 4. I also own a Galaxy Nexus, and aside from the black levels, there is another area where the AMOLED screens shine: motion handling. LCDs tend to blur images in fast motion, motion resolution isn't usually very good. This is very noticeable when watching action films or sports, for example.
However, AMOLED screens are very fast thus their motion handling is on par (or even better than) with plasmas, which gives you crisp and clear images even when moving (blur ocurring depending on the shooting conditions but that's a whole different story).
So, to summarize the differences between the screens:
- The screen of the Nexus 4 will be slightly clearer, the pentile matrix used in the AMOLED screen makes it slightly more "blurry", although due to its high pixel density that's usually hard to see.
- The screen of the Galaxy Nexus has perfect blacks, the screen of the Nexus 4 doesn't. The point is, will its blacks be "black enough" even for multimedia? "Black enough" is very subjective...
- The screen of the Nexus 4 will probably handle motion worse than the Galaxy Nexus one. The point again will be if it handles motion well enough.
It seems that the screen of the Nexus 4 is slightly better for reading and web browsing but slightly worse for multimedia. I only have a Galaxy Nexus (no access to HTC One X, etc) so anyway I can't really compare.

Well it all depend on taste. I think the IPS screen for me will be better for contents consumption. Text clarity is a very important factor for phones and RGB array IPS excel here. Better color accuracy is the most important factor for me, without the banding, retention and dark spots that I deal with on AMOLED. I only fear of the chance of backlight leakage that can happen with regular LCD.
I know the response time of the OLED screen have very fast, but I don't do heavy gaming on small mobile devices. It also have ultra wide angle view and wider color gamut (poorly tuned however). I also like its performance outdoor and contrast. But it can be s battery eater.
Also I missed the curved glass of the AMOLED screen, before anyone say the Nexus 4 screen is curved, by what I see from the verge video it isn't, only the external glass seems to be and just a little by the edge, not the same effect.

The Nexus 4 will have better viewing angles than the AMOLED.
Sunlight will probably be better too. Colours will be more realistic, and battery life will be lower apart from on a black screen.

I don't like the oversaturated colors of amoled screens, and true colors are important in my work, so I much prefer a good IPS screen. Too bad about the blacks though.

I hope the Nexus 4 display will be better. On my Gnex whenever I watch videos with dark scenes or blackground, I get this noise/artifact thing in the background. Do you guys get that? Also, black is technically not completely black on the Gnex because the pixels do light up a little for faster switching. There are a few threads in the Gnex forum that talk about that. It is only noticeable when there is very little or no ambient light. You can test it by going to a dark room and open an image that is completely black. You will see some dim light coming out from the AMOLED.

I would have to say my biggest concern is how the screen will perform in the direct sunlight. Of the phones I've had the gnex does best in direct sunlight. Very easily readable and use able in direct sunlight. All my other phones have been washed out in the sun. They where some form of lcd's, but not any of the newer generation super performing lcd's that are out now. The HTC Rezound I had was the best LCD screen I've owned. Amazing picture but suffered in the sun.

I think that's either black crush like the original note had or the black spots which nearly all amoled screens get because of the way they are produced.

Does the GS4 have the best phone screen?

I was playing around with the GS4 yesterday and the screen probably impressed me the most. I held it next to the GS3 and it was quite a bit better: sharper and brighter.
I haven't had the opportunity to look at the One yet, but I have to think the GS4 is a strong contender for the best phone screen. Of course it depends on your preference for AMOLED versus LCD; I probably prefer the former.
So to those who have been using the phone: how would you rate the screen? Do you consider it a big jump over the GS3 and how would you compare it to other phone screens, especially the One?

WAY better than GS3 but trades shots with the One.
I prefer a larger screen with true blacks so I prefer the GS4's screen. If you prefer a smaller screen and colour accuracy then the One's screen would be better.

"The best" is highly subjective. For instance, if you prefer outdoor visibility, it's still nowhere near iPhone or the One. That said, I prefer (properly calibrated) AMOLEDs for the contrast ratios and superior blacks despite all the drawbacks
Personal preference, really.

I have a One, and I have had a look at the S4 display. I have to say both displays look great.

You like Amoled then this is the best, if you like LCD real colors then One is the best. Personally prefer the One display.

It really depends on your preference. I have owned all the Galaxys, and some sony/HTC`s and i will say it is not.
There is no doubt the S4 screen is amazing, but only when it comes to colours. After using the S4 for a period of time, my eyes is starting to get tired. And thats because of the deep, saturated colours.
In the end it comes up to your personal preference. For me the Xperia Z/One is the best one. Nothing beats watching a movie on an LCD-panel.

While I love the screen on my GS4, I must humbly admit the SLCD3 screen in the HTC One is superior. While the blacks aren't completely black because it can't shut off pixels like AMOLED does, it's blacks are however very very impressive, color accuracy and sharpness are also more superior on the HTC One as well (the S4's Adobe RGB mode, aka (Professional photo) looks off a bit, especially on reds, so don't be fooled into thinking this option will make up for the inferior color accuracy). The only downside to the HTC One's screen, is it's only 4.7" which is a knock in my opinion as I prefer a larger screen.

So use Adobe RGB mode...

No it has really bad ghosting.

One of the best. I've recently switched to "movie mode" as various professional display reviewers have noted this mode as having the most accurate colors and I've been loving it. Feels more like an LCD which I used to prefer. I was also surprised at the amount of additional detail I'm seeing in movie mode that were not present in standard (for instance, the tapatalk app icon)
You will need a day to adjust from standard mode, but once you do I'm betting the standard will be hard to look at for you.
The resolution and PPI speak for themselves, obviously.

Note 2 screen looks great. No pen tile.
my gnote2 is bigger than your puny iPhone.

The s4 screen has a wow factor since the colors pop and the blacks are inky. The One's screen is great too much IMHO, the I prefer the S4 since it is bigger and more vibrant. The One's screen is like looking at the Iphone's screen but bigger since even on the Iphone you can't see pixels so it didn't wow me as much.

Guys i just compared my s3 to also mine s4 and must say the s3 display is sharper and I see more details on it. I just run few same clips on both. Can someone confirm it.

Samsung displays are horrible when it's outside in bright sunlight.

If you want vibrant colours they are the best. If you want realistic I'd say the One and iPhone 5 are the best. The movie mode is very good on the S4 but it's not as well calibrated as the iPhone 5s screen. Looking in the forum the S4 has ghosting/smearing and some weird pink tint issues. AMOLED screens also are poor in daylight and can get burn in.

Now that it has an option to show accurate colors. Displaymate rate it on par with iPhone 5 which is rated as the best LCD screen they tested in a mobile phone. For me SGS4 is the best out there simply because it offers best of both worlds. There is a mode to show vibrant colors which I personally like especially when watching movies. LCD will pale in comparison next to AMOLED which can show pitch black . It is still Pentile arrangement however I tried hard looking closely as I can and men I can't see any pixels or cross hatch pattern that I can detect on SGS3. I even think that it's icons are much sharper compared to iPhone 5. Now that the Pentile weakness has been totally eliminated by ridiculous 441 pixels per inch. Is there another phone out there that can beat this in terms of display?
From Displayemate which is world renowned for display diagnostics
Comparing the Galaxy S4 with the LCD Display on the iPhone 5:
The iPhone 5 is now more than half way through its product cycle, which is important to keep in mind for our comparison. However, high-end LCDs like the iPhone 5 are a very mature and refined display technology, so other than screen size, resolution, and the Pixels Per Inch not much is likely to change in the next generation, no matter what Apple decides to do. The iPhone 5 is significantly brighter than the Galaxy S4, particularly for screens with mostly peak white backgrounds. Its color calibration is a bit better, although the Galaxy S4 has a more accurate White. The Galaxy S4 has a much bigger screen, higher resolution, higher PPI, much darker blacks, and better screen uniformity than the iPhone 5. They each have their own particular strengths and weaknesses, but if you scan our color coordinated Comparison Table below, both displays are quite good and comparable overall – so it’s currently a tie – we’ll see how they both evolve and improve in the next generation…

With the current pentile matrix they are using and as high density as the 1080P display is, it doesn't affect the quality of the display.
Pentile really is no longer a useable arguement.

Seriously guys, calibration is not an issue. As long as you can get rid of that blue tint, I'm sure you'll get Perseus kernel with top calibration. I do on my Note II and it's absolutely perfect, if not better. Properly calibrated, AMOLEDs have an advantage when it comes to the contrast ratios.
Brightness still sucks though.

I've alway thought Samsung screens always looked too blueish and not so true to life. HTC always seems to get it right when it comes to screens. Just my opinion.

The ones slcd is superior to the sgs4... Yes the colors are more vibrant and black is real black... But there are too much downsides in my opinion:
- White just doenst look white - ok and full brightness, but not below that
- Loss of detail in dark areas
- Low brightness on automode (even on +5)
- Low brightness on maximum brightness (the ones slcd is superior in sunlight)
- Burn-In
- Pentile - still visible for me
- Smearing / ghosting
- power consumption on browsing
- red black (fixed?!)
