I've seen many phone screens but so far the sharpest crisper phone screen I've seen is the sidekick lx 09, followed by the iphone 4 and the tmobile G2 and the nexus one. The reason for being that the sidekick has 854 x 480 resolution in a 3.2" screen.
The iphone has a 640 x 960 resolution in a 3.5" screen about the same resolution but the sidekick has more pixels per inches because its a smaller screen than the iphone.
Tmobile G2 and the nexus one with a 480 x 800 resolution are the sharpest screens I've seen after the sidekick lx 09 and iphone 4.
What are the sharpest crisper cellphone screens you've seen so far?

Really? The G2 and Nexus one? Yeesh... First would have to be iphone 4 though the screens too tiny for my taste. From there I'd say the Samsung Focus, then the Dell Venue Pro, from there it's all downhill... I don't think android really shows the beauty of a screen properly or I'd put the Galaxy S line somewhere on there... probably along-side the focus.

Galaxy s phone screens aren't shraper than the G2, they have less pixels per inches, and I don't like the super amoled either. And have you seen the sidekick lx 09? Its belive to be rank as the sharpest screen in the world because is so small and has so many pixels per inches. The screen is ****in gorgeous, iphone 4 is nice too

PPI is no big deal to me especially considering the difference in screen size and the fact that nothing looks sharp on an HTC LCD screen. The lx 09 I guess has a decent screen but for a tiny non-touchscreen screen that doesnt really mean much... iPhone 4 has an awesome display, just too small a phone and too ugly a UI for me...

Super lcd has is the sharpest after retina display on touchscreen phones, the super amoled isn't as sharp as the G2's screen. And to add that the colors on the super amoled look over saturated no natural colors, only thing the super amoled got on the super lcd is the blacks lol the only thing super amoled got better than lcds. I don't understand what yu mean by that htc screens aren't sharp?

The no natural colors argument is an excuse for lack of quality. The vibrancy of AMOLED and SAMOLED looks much more natural than the washed out colors of HTCs LCD screens... If by sharp you mean PPI then I'm sure I could get a phone with a 3 inch screen that owned any of those... However for all visual purposes AMOLED looks best with SAMOLED in a close second (SAMOLED puts a blue hue on white colors that I dislike) then in distant last is LCD screens. I'm watching the same show same episode of smallville on an HD7, a Dell Venue Pro, and a Samsung Focus right now. The Focus and the DVP are right on par with each other, the HD7 is trailing... I mean the Focus has 223 PPI which unless you're holding the phone less than a foot from your face is hardly discernible and the DVP is at 228, again barely discernible. There really isnt much difference between that and the 256 of the g2 and with that you sacrifice screen size and get caught on an LCD screen... no thanks.
I love how this is just a hate thread. I'd prefer to read something other than this hateful garbage. WAHH WAHH HTC PHONZ SUKS KAWS I GOTZ AMOLED. Perhaps the iPhone and G2 ARE sharper quality physically, but the human eye can barely distinguish. My screen looks beautiful whether you agree or not.

I was talking about the super amoled which you agree sucks with white colors, and not only that but it has a greenish tinge on yellows that looks very unatural, I haven't seen an amoled screen, I only seen OLED and SAMOLED, my cousin got the epic and super LCD has way more natural colors, look at the youtube video comparison and you'll see what I'm talking about and remember to YOU it looks better than SLCD not to me, it all depends on what looks better to you I personally don't think colors are washed out like you claim on SLCDs, however I think colors are over saturated on SAMOLED. Thank god htc can't implement SAMOLED displays on htc devices hopefully they'll keep SLCD since samsung is the only one that makes SAMOLED

What phone do you have? And which screen you like better SAMOLED or SLCD?, and listen some might think Samoled has better colors but who cares IMO, and probably yours too, SAMOLED is does not have better colors, we all have different taste and opinions, and SLCD out of all I've seen is the best, its natural in colors, reds doesn't look like. Orange or like they're bleeding and yellows don't look greenish, it is very sharp and has great brightness, if it only had the blacks the SAMOLED has it would be the perfect screen, but still I could give two cents for how black are the blacks.

I agree that it looks pretty nice... I personally prefer AMOLED over the alternatives Super LCD included. SAMOLED is a little out there but I'll take that over devices with the basic LCD screen that most devices are still harboring. I mean all in all it's not a huge difference between most devices but AMOLED and things like that... they just appeal more to me. The colors even though they can be almost cartoony are still visually enthralling. AMOLED is good, Super LCD would take second, from there I'd say amoled, oled, then LCD. Pixel density is hardly visible to the naked eye so as long as it's not just terrible it's all about the type of screen... this is all just my opinion though.

I understand, you like more vibrant colors while I like more neutral not that vibrant or not washed out, we all have different taste so we can't say one is better than the other because its all base looks and on opinions. Just like some people like strawberries some don't lol

Agreed, I think my distaste for the washed out colors is because a heavy portion of Windows Phone 7 is black and blacks are not too good on LCD screens as you mentioned earlier.
I like Super Amoled actually, nevertheless, I will wait for WP 7 phones from Nokia.
They will throw the Clear Black Displays in them, I reckon. And the clear black displays were proven to be the best in a GSM Arena review.
BTW, I don't like Nokia, but I always go for the best.
..................
Hello,
I've been reading these forums for ages and decided it was time to actually share some thoughts.
Since my HD2 broke a few weeks ago I am looking for a new phone. I wanted to buy a GSII or HTC Sensation but after hearing about HTC's One line I decided I could wait another month.
Now I am considering both the One S and the One X.
My thoughts about these phones:
I do not really care about the processor as long as the phone runs smooth, I expect them both to be fine at this point
The lack of a SD-card slot doesn't really bother me as well
A non-removable battery will be something I have to live with
Now the real differences to me are:
Size/form: The one S looks like a way better sized to me. I doubt I could like a phone beyond ~4.5". I also think the black ceramic looks really beautiful. The One X looks good as well, but the vulcano-shaped camera is just ugly to me.
Costs: the One S is a bit cheaper
Display: reading the reviews I think it's easy to conclude the One X is definitely way ahead of the One S
Now my question: Is the qHD Super Amoled Pentile display on the One S really that bad? Sure it might not look good when viewing at 15cm distance. But that won't be the way I will be using the phone. I read about the Galaxy Nexus and the Nexus One having a PenTile Amoled screen as well. Though a lot of people complain about the Nexus One, I do not hear that much complains about the Galaxy Nexus' screen. Is this due to the higher resolution?
How would the One S' display look compared to, say, the HD2 800x480 WVGA display?
Can't wait to test them in real life!
Advantages of qHD Pentile SAMOLED:
- Excellent contrast
- True Black
- Colors that pop out of the screen
- In 4.3" is a decent PPI but not best, meaning it will sharp but it could be better (coming from HD2 you shouldn't notice that much difference unless you compare it side by side with a higher resolution screen)
- Longer battery life IF using a lot of black (which ICS uses, but webpages don't)
Disadvantages:
- Not so sharp text (because of Pentile Matrix and not so high resolution combined)
- "Dirty Whites", no matter how well calibrated is the screen white is one of the colors that usually suffer more with Pentile Amoled screens
- Shorter battery life IF surfing the web a lot or using applications with predominant white color
- Poor outdoor performance in shiny days compared with many LCD screens
I'm sure I'm missing some others, but that pretty much sum the pros and cons of SAMOLED screens with Pentile.
And you're right about Galaxy Nexus screen, the only advantage that alleviates the sharpness problem is the higher PPI, but even so the problems are there just less noticeable.
Compared to the HD2s 64K only colors screen I think you will be delighted with any of the newer screens, pentile or not.
I had an Amoled Desire and indeed the pentile layout is a little less sharp but it didn't bother me at all and I will be happily buying a One-S when it becomes available.
You should see what people say about the Droid Razor because that has a qhd samoled pentile screen. Check reviews and stuff, from what I read (very little) the screen isn't that great according to theverge and engadget, but go check it out at the Verizon store and you will have a good idea of how the screen will look. IMO its just a small "issue" because the rest of it is pretty bad ass.
Sent from my Galaxy Nexus using xda premium
Yeah, I have a friend who has the RAZR and the screen is pretty shoddy. Its not so much the sharpness, but it has a really strong blue tint if you look at it even slightly tilted. Its not even a tint, white turns into blue. Not sure if that just came from a bad batch but if that's the screen that the One S will have I have to be a bit concerned.
My Vibrant has a slight blue tint as well but its not nearly as strong. If the One S has a screen closer to the Vibrant than the RAZR then it's perfectly fine.
Nice to read your opinions! It's always nice to see how people have totally different opinions about the same thing.
I, really like a sharper, higher resolution screen. I kinda get annoyed when text gets blurred. Yet if it is only really noticeable when taking a closer look I won't mind.. The colored white is something I am a bit worried about though. I quite like the more saturated colors.
I think we can conclude that I (we) will just have to wait to see the device in real life. As long as it does not bother me when watching from a little distance I guess I will take it! Apart from the screen the specs are great and it just looks very very nice..
I didn't think there was anything wrong with the AMOLED screen on the One S when I had a play with it on Friday just gone, and colours were noticeable brighter than the One X's SLCD2 screen (as you'd expect)
The weight and thinness of the One S was nice, though - didn't expect it to be so light/slim
The Screen seems to be that same like the one in the motorola razzr. I did have the razzr for a few days and i can tell that i didnt like it. Colors were not accurate and in some circumstanced it looked really really bad (red backgroud with text on it)

Thanks for the impressions.
I think that this may be a Motorola thing. I had a look at a Droid 3 yesterday and despite it being qHD, it was noticeably more pixelated than my Vibrant at WVGA. I barely notice the pixelation on my phone unless I really look for it. Does Samsung provide these screens? Maybe they're sabotaging their competitors?
doesn't seem too bad even compared to the one x

You'll never notice a difference between two small screens from a far distance, remember you use a phone very close to your face, and even then not everybody see things in the same way and some people claim not being able to notice the pentile pixelation (others like me see it).
For me the pentile SAMOLED is good if not the best... I have a Galaxy S and I found the screen to be pretty good(Was using LCD droid before).. Anyways gsmarena reported the pentile screen of the One S to be better than earlier pentile screens.They said HTC used some of its tech on the screen resulting in better pentile SAMOLED.. Btw am also planning to buy the One S .. Very disappointed by Samsung support.
Here is the article on the One S screen
http://www.gsmarena.com/htc_one_s_and_one_x_displays_detailed-news-3940.php
Yeah it's kinda weird how everyone is really positive about the One S' screen. It sounds like it has the same screen as the razzr, and a lot of people complain about Motorola's screen.
Anyway, maybe they improved the PenTile performances. We'll see soon enough!
I think Motorola just does a poor job calibrating their screens. I have no problem with the Pentile screen on the Vibrant. Its obviously no retina display but it's very sharp considering the screen size and resolution.
The only thing that sort of bugs me about the screen is how saturated everything is. Some people like that but I would prefer more natural tones. This is just personal preference though.
As an owner of AMOLED desire, i can say that its the best! It depends a lot on when and where you use your phone most. For me, thats in office and in my room at night.
Especially in a dark room, nothing can compare to the infinite contrast and excellent blacks of SAMOLED screens. Also very good for showing pictures to others, as they appear vibrant.
I guess my 2nd preference would be the IPS display from LG (like the one on Optimus 2X).
One VERY annoying aspect of SuperAMOLED is the burn in and wear.
I had an SGS before and the black statusbar got burned into the screen after 3-4 months of use.
It won't go away no matter what and it gets super annoying when holding the phone in landscape and watching video.
The wearing of the screen makes the colors less vibrant and not as bright.
I did love AMOLED before it burned in but after that I couldn't take it anymore so I got a sensation and passed my SGS down to my little sister.
I'm not sure that is normal.. though all screens can get some degree of burn in, it shouldn't be permanent.
Could be just a bad phone?
Both me and wife have amoled phones (me desire, her sgs) and don't notice any Burn in.

It would be nice to know how the screen compares to say a SGS
I have a one s and my wife also, no issues with screen this is now my 9th HTC and clarity and colours are fine, you'd have to be very picky to complain that its not up to the job. This is one cracking phone, i'm sure i'll find some bugs but for now its great.

I am thinking about both One X and One S, but screen is really important for me, because I had iPhone 4S for more than a month and can say, that I see so many pixels now So the question is, can you see pixels on One S screen? Is it sharp and clear?
So currently these 3 types of display techs(mainly their variants like Super AMOLED, Super Clear LCD, Super IPS LCD, LED Backlit LCD,IPS TFT etc) are the main kinds of display technologies which can be seen on the latest phones.
I have a few doubts regarding this topic.
1- Which technology gives the best color reproduction?
I know AMOLED sucks at this field.What about Super IPS n LED Backlit LCDs n TFTs?
2-Which one has the best viewing angle?
3-What is all this pentile matrix stuff about AMOLED Displays?
4-Longevity,which one lasts long without noticeable degradation?
5-One technologies main advantages/disadvantages over another

1 amoled has very good contrast. but pixel density also important. Phone could have anyone of these displays and have varying dpi
2 IPS has the best viewing angle
3 i heard of that I've have to google it.
4. Longevity has too many variables. depends on use quality and always random dud phones so idk.
5. depends on what you want it for reading vs watching video the size of the screen quality of a product. you can get knockoff iphone with rentina like display doesn't mean cheap phone will last longer then a lessor display. It's more of a personal choice than an overall one better than another.
1. Depends if you're looking for real life looking colors or bright, vibrant colors. Out of the box AMOLED is the latter, while all LCD's are the former. However, all these screens can be adjusted (Android phones anyways), so it's not such a huge issue.
2. IPS LCD has the best viewing angle, but AMOLED is so close behind it's not a deal breaker. All other LCD's would be behind them, but the amount of which depends on the quality of the panel. iPod Touch viewing angle is terrible, while Xperia Play's is amazing for an LCD.
3. Pentile is just a different sub pixel arrangment. It can apply to LCD or AMOLED, it's just seen more on AMOLED's because it makes those displays last longer. Pentile screens don't look quite as crisp as RGB layout screens, but it's harder to notice with the 720p displays out there now.
4. Traditionally AMOLED doesn't last as long as LCD, but it seems to be panel specific. Some AMOLED panels can last really long. All in all you shouldn't see issues within a 3 year phone contract with either.
5. Totally personal preference. I like AMOLED's myself, mainly for the infinite black levels, vibrant colors, and very good viewing angles. Some people like LCD's because the colors out of the box are more natural. Also some like how there are 720p RGB layout LCD's on phones. AMOLED hasn't been able to do this yet, it has to resort to pentile for those resolutions. Then again, it's hard to notice at ~320 PPI

Personally i seem to prefer SLCD over SAMOLED, the whites are bluish and there's a weird hue in all colors except black in amoled, not sure why but the blacks are true blacks which is not the case in lcd where all colors are perfect except black is kind of grayish because of the back light.

My AMOLED colors were slightly off when I got my phone (a little on the warm side). With a quick color tweak the colors look amazing now, along with the true blacks.

Super Amoled Plus and super LCD are the higher end panels and bring out the best of each technology. However nothing beats a good ips panel in my books. The colors are flawless, and the viewing angles impeccable. That is all I need.

AMOLEDs provide true black because in this technology, each pixels produce its own light(unlike LCDs,in which a single lightsource illuminates the entire screen). And when black is needed to be produced,that individual pixel is completely shut down,thus zero light is emitted.Hence true black.

Technically IPS is a really good TFT panel. Like how a maybach and a c200 are both Mercedes. IPS being the maybach ofcourse.
And technically an LCD is also tft. But then it starts getting confusing if you go down that road.

amoled is much more colourful than the others.
A I-Phone 4 looks really pale beside a Galaxy S or a Galaxy S2.
Amoled has limited life-time and looses brightness.
The power consumption is dependent extremly on the brightness of the colour.

Power consumption is EXACTLY what interests me most about this. I remember reading a couple of years ago that Sony Walkmans using OLEDs offered vibrant colours while using far less power than LCDs. The trouble is I'm having trouble finding more information on this now that I'm looking at OLEDs in smartphones. Is this true, does OLED use less power, does it not use a backlight like LCD?
I'm dying to know because I bought a cool phone a few months ago, but hadn't learned about battery usage/capacity and now I HATE the phone for it. I'm looking at the OLEDs e.g. on the Motorola RAZRs (with 2000 mAh batteries) and I'm curious about them.
UPDATE: I just found a simple document composed from companies and organisations involved in OLED production which, they say is designed to eradicte myths on this. You can see the document here, and on power consumption, my brief understanding is this:
LCD: uses maximum power to display any image
OLED: uses minimal power on darker images, maximum power on brighter/whiter/colourful images - white/very bright images use more power than LCDs
This leads me to think that switching to OLED can only result in at least some benefit in battery life, no? I think most of us on Android are conscious of the use of black and white in the UI, wallpapers etc. so something like this would help. Is it a significant benefit? A backlight on a TV plugged into the wall is fine, on a smartphone I can see why it's a battery-killer. I note the caveat about OLEDs using more power for white and very bright images, but the way I see it, unless you're using a white wallpaper, this isn't an issue. I speculate a power saving when all is accounted for.

So, if a TFT display is considered not quite as good as an AMOLED or an SLDC…how could a difference be noticed between the Xperia Z’s TFT display, the SGS4’s AMOLED and the HTC Butterfly’s SLDC3 – all 5 inches, all 1920x1080? Battery life/colour reproduction/daylight visibility?
Thanks for the input.

I'm sorry for breakin' in this late, but... I hope to help in the future decisions.
We're mixing some things here:
LCD is a technology. AMOLED is another technology.
TFT is a sub technology that must be applied under one of the mentioned before.
TFT is an array used to feed large displays (a mobile phone is already a large display).
Since phone displays are "large" either LCD or AMOLED need an active controller to maintain brightness in each pixel.
This is A BIG difference between OLED (PMOLED) and AMOLED.
As SharpnShiny mentioned mp3 players/walkmans (small displays) can use OLED which use much lesser power than AMOLED.
In OLED/AMOLED displays each pixel produces it's own light, which can be a good power saving if most of the image is black or dark, because, in black the pixel just doesn't light up.
In LCD there's permanently (monitor ON) a "backlight". Even if the image is black! What the display does is block the backlight when it needs black.
About power consumption in either cases... I don't think there's a really noticeable difference because it depends a lot on the usage!
UPDATE: Sometimes the best way to save battery is to tweak several settings (including the Kernel) as the display brightness levels and thresholds.

Thanks! That's what I intend to say. It seems many people misunderstanding about TFT.
TFT is not a panel technology in comparison with TN, MVA, IPS, PLS, AVS, AMOLED,....
1- Which technology gives the best color reproduction?
I know AMOLED sucks at this field.What about Super IPS n LED Backlit LCDs n TFTs?

In other hand, Led-backlit is a similar case, it is a type of backlight, cause the LCD need the illumination. And there are 2 kind of LED, Edge and full-array. In mobile, almost is edge-led because of low cost and thickness. Full-array Led backlit only appear in several high-end TV models. The older tech is CCFL, which consumes more power
It means that a new LCD display which uses IPS panel also include a TFT layer and an edgeLed-backlit.
Sorry if any typo mistake. My bad English
Does anyone here know much about SAMOLED? I read in a phone review that it's more a marketing term than actual performance difference over AMOLED, but I'd prefer to double check that. For anyone who hasn't seen that term, the S is for Super (don't laugh yet!). I think the Motorola RAZR i and the Samsung Galaxy S III Mini are using SAMOLEDs.
I've been comparing my new and old phone screens when considering this thread. I have to say I prefer the TFT LCD screen more than anything. Even with a lower resolution, the images (video and static) is beautiful to me. My RAZR i has a higher resolution but a pentile matrix SAMOLED. It reminds me of phones 5 years ago, the matrix gives the impression of cheap pixel displays in my opinion - but I keep reading it's amongst the most battery-saving screens in the mainstream smartphone market and for that I am greatful.
I get noticeable battery drain difference by turning down the brightness on my AMOLED screen.
Decreased brightness also extends the life of the display.

Yes. SAMOLED is the Super AMOLED from Samsung.
I wouldn't dare to say that it's just a marketing stuff... Because it's a little about "sub-pixels" and their layout. I would say thay the AMOLED technology is there with Samsung's engineering so that picture could get better.

That's what I meant in my last post, under the UPDATE statement. Also try to tweak your phone's clock (if you haven't done it yet).
Mine (a poor 600MHz ZTE Blade) is working from 245MHz to about 650MHz depending on the load (from underclock to overclock).
I just want to know if you satisfied with the One S pentile matrix screen. I have a Sam S2 and recently bought a One S (S3 chipset) and i noticed the lcd is very pixelated (if its a real word, sry for my English) compared with the S2's screen. Its not too bad but noticeable and a bit disappointing. How you live with this?

By not being incredibly picky. The phone wasn't cheap, so before I signed a contract, I made sure I was happy with every aspect of the phone. While I do agree it's pixelated, and that my Sensation had slightly better quality, I am incredibly happy with the screen. I'm rarely centimeters away from the screen so I can live with it especially because the color reproduction is amazing.

I think you just get used to it after a while. I couldn't stand the screen when I first got the phone, It stopped me using it regularly because I just used to get annoyed at the screen! (sad I know) But now I don't even think about the screen because I'm so used to it. I came from the Desire S which had a S-LCD display and a 480x800 display so that was a very good screen considering it was only 3.7 inches! I found the amoled colours of the one s to be extremely saturated. I didn't like the yellowish/blueish whites and the fact that every time you slightly changed the angle of the screen the colours would turn slightly blue. Text looked pixelated especially on a white background, that doesn't help considering a key part of sense 4 settings is all white background. It took me a good month to get used to the screen and 3 months in, I'm used to it Possibly getting the Nexus 4 soon so doubt I'll have much longer with this phone anyway.
Sorry for the little off topic might pickup a one s didn't want to start a new thread...
I saw the one s at my local fido store and damn its so snappy even whit sense !! But i tried the one x and it was somewhat slower is this normal ? Flicking through homescreens just werent the same..

I did notice it some when I first got it, but I really don't anymore at all, and like was said above, I'm never close enough to my display to really notice it. I think the screen is incredible, as is every other aspect of the phone. I LOVE my One S.
I thought it would annoy me, but the phone was free so I decided to bite the bullet. I've had the phone 6 months now, and I really don't notice it at this point.
I love the one S display, sure the screen isn't as sharp as the GN, GS 3 and one X etc. and you don't get as much screen real estate but everything else is just as good, if not better:
- one of the best screens in sun light, don't even have to put my screen above 70% brightness in direct sun light in order to be able to make stuff out easily and this is on a darkish background too, MUCH better than the GN and GS 2 in this area
- colour reproduction is superb, my screen is pretty much perfect, whites are super white, brighter white than my dell u2311h, iirc a review site stated that the screen is better calibrated than the GS 3 SAMOLED screen
- no tinting at all on mine, usually with AMOLED screens you get a blue or yellow tint, which is noticeable at angles on whites but not on mine (this varies with every single screen though)
- of course blacks are black and the viewing angles are superb
- high contrast ratio etc. so games and videos look great
I only notice the pentile when looking at white text on black backgrounds and a few icons, but only when I really look for it and have my face pretty close to the screen. I find the one S screen to be sharper overall compared to the GS 2 screen.
I have had the one S beside the GS 2, GN and GS 3 and personally I didn't like the GS 2 screen at all, res. is too low so things are huge (felt like an old man using a phone designed for people with poor eye sight ), colours are far too saturated/warm. The GN screen is nice and sharp but the colours aren't saturated enough, rather dull over all and plus both phones are poor in comparison to the S for view ability in the sunshine. The GS 3 screen is great, better than the GN, however, I think the one S screen looks better for colours.
Anandtech more or less summed up my thoughts:
What’s different, however, is how well HTC has controlled the color temperature and gamma compared to Motorola in the RAZR. As shown in the HCFR galleries below, gamma is pretty close to 2.2 until you get to the high end, and color temperature is pretty close to 6500K, except at the two darkest grey points. This is so much better than any other OEM calibration of an AMOLED panel I’ve taken a look at, which is rather humorous because the panel is undoubtably Samsung’s. HTC is also letting the panel go pretty bright, up past 350 nits, instead of clamping it way down around 200 (I’m looking at you, Galaxy Nexus) to save power. I also haven’t noticed blacks not being totally off on the One S like I have with some others. Of course, colors are still massively oversaturated if your source color space is sRGB.
I’ve griped about PenTile RGBG before on this panel and other SAMOLED displays, but I find the One S to be completely enjoyable in spite of having it thanks to two things. First, how well HTC has controlled the panel (no awful hues, weird white points, or dramatic shifts as you change brightness) - this is basically the best I’ve seen this particular panel, and until SGS3, the best I’ve seen AMOLED in general. Second, because HTC doesn’t appear to be applying any processing that applies sharpening (like Samsung’s mDNIe) to text.
How you feel about PenTile really is the final factor: it’s there, but I’ve slowly become accustomed to it after staring at it for so long. If you go back to the Nexus S days, I was one of the most outspoken critics because of how large those subpixels were. With small enough subpixels (below visual acuity), PenTile starts to make sense. In other news, HTC moving back to Samsung AMOLED for phones is an interesting move after supply issues forced HTC to SLCD with some earlier phones, here on the HTC One S however, it looks great.

My solution: Get old. You probably can't see all the minute issues you guys think matter, and you don't really care if you do. Every phone I've ever had has had a better screen than the previous and I think that's pretty nice.
I hate the screen, drives me nuts. I found that using a theme that mostly uses blacks and whites makes it more bearable though.

Have to agree. Thing is apart from the screen it's a fantastic phone. It's so fast, battery life is great and the camera is great. I don't even think the screen would be that bad if it wasn't pentile it's just the fact that it's a pentile display it makes the phone look way more pixelated than it should be
I think I need to go to specsavers, I've never noticed a problem with the screen.
The screen on this is amazing. Don't notice any pixellation whilst on it . It's quite an improvement over my old Wildfires QVGA 3.5 inch 240x320 TFT display.

If you switched from Wildfire you cant see this but if you had any phone in the alike pixel density and resolution you can see the difference. According to others opinion its not bad, the perfect color saturation, contrast etc will eliminate the bad feeling about those subpixels.
HTC does calibrate their screens nicely
I suppose it depends on what you're used to. When you come from an iPhone or high-end LCD-screen you probably will get annoyed with this display. However, when this is your first touchscreen smartphone or when you had a smartphone with a low-end display before this one, you will probably be able to cope with the slight pixilation.
Personally, even with this being my first touchscreen smartphone and coming from an E72 with a PPI of about 170, the display of this device would be the only reason for me to buy a One X or Nexus 4. That being said; you don't buy a smartphone solely for its display, you buy it for the complete package (price, battery, design, display, size, cpu/gpu, storage, support, OS, cloud integration etc.). And for me, the package the One S offers is more compelling than that of most other smartphones one the market.
I compared the One S screen to that of my Galaxy Nexus and honestly, when it comes to clarity, there isn't much of a difference. If you are in your twenties with near perfect eyesight and able to hold the phone less than a foot from your face then you will probably see pixelation but at normal distances it isn't an issue. For me it seems that anything above 250ppi is fine - my original Galaxy S was less (I think 233ppi) and that display was pixelated to me, but then again it was an earlier generation screen, I'm sure there have been other refinements besides resolution since then.
One S 256 PPI
Sam Galaxy S2 217 PPI but looks sharper.
Its all about the pixel placement, pentile matrix is a pattern. This matrix gives us better colors because more subpixels. Google for it there are many info i cant explain it in english
I come from an LG Optimus 2x, 4'' ips display, 800x480, and I feel this display better IMHO.

I said Galaxy S, not S2.
Yes the S2 was/is superior despite the lower resolution thanks to the RGB arrangement (not pentile). The original Galaxy S was pentile, and not that great by today's standards.
It's okay, but I'm actually kind of unsatisfied with the blacks. I thought it would be completely black, but when I have a black picture shown on the phone in a completely dark room, the screen still lights up

I never really cared much for the AMOLED VS LCD wars, my favorite screen was whatever panel had the best calibration and just looked most natural.
Given that Samsung's new AMOLED panels are extremely well calibrated, I was a little more excited to take a look at their panels over a slightly longer period of time. I've definitely toyed with their latest gen at B&M stores, but I finally had a chance to really sit down and compare my new X with my GF's new work phone, the S6 edge.
The first thing you notice about the S6's whites are that they're not white like on the X, they're sort of green-tinged. The S6 also offers multiple screen modes, but the whites are still the same in nearly every mode.
The Samsung AMOLED panels really excel when you're looking for depth in very dark scenes, but for an average person like me who likes to surf the web, white backgrounds are what you'd encounter the most.
And considering that material design will be the standard for a at least a couple more years, I don't see my opinion changing at this point.
I for one, am glad that Moto went with an LCD screen this time around. Yeah, moto display is worse off for it, but whatever, that accounts for literally 1% of my on-screen time.
Agreed. Coming from super amoled to this screen is a blessing.
Bangin' on my unlocked/rooted
Moto X Pure
eh. my note 4 amoled looks damn good. the whites on the moto x don't seem as white which is funny. maybe I just have a warmer panel, but the whites are a bit warmer on the LCD compared to the amoled which is opposite of what it used to be.

i've always been a huge fan of LCD over AMOLED. I always consider it a plus when a phone has LCD. Would gadly take the small hit on battery life. I always like to "cooler" whites and LCDs seem to do a better job of it. By far my favorite screen to date is the one in the G4. It's the closest i have seen to a LCD that can hit deep darks and be bright like AMOLED but hold the good LCD whites I miss it sometimes
I know! I used to love my amoled on my note 3 but after switching to an ips lcd damn it looks so gorgeous and none of those yellow whites anymore!
I was thinking of getting S6 after reading all that praise to supper accurate and great amoled panels then I went and checked it out my self just to find out its not entirely so. Black's in the darks have very little gradient and are simplybtoo dark. If set sreen to basic mode to get sRGB color space whites are not whites but dull yellowish . I checked couple of panels and they all looked the same. I honestly don't get all that buzz around this panel.
I returned my moto x pure edition precisely because whites were yellow. It was as bad as my current Note 4. I'm now wondering if my Moto x Pure was defective. Try it again or wait for 6P? Decisions. Decisions.
The 6P may be yellow, or white. It seems that it's a crap shoot with all phones no matter the brand or the tech used for the screen.

You can always wait for a kernel and change the color balance tho
The 6P might have the same problem, like someone said, every phone its kind of a lottery with the screens
I was thinking about getting the 6P but considering that i would only get the 64gb version, i dont know if i could justify the extra $150

Me too. I like LCD displays over AMOLED. LCD in my experience always tends to be brighter with white looks really white.
However, this doesn't seem to be the case with moto X PE. I got a screen with yellow tint. White pages look really yellow when I put it next to my OnePlus One. I wish there is a way to change the screen color temperature.
Moto's own feature (moto display) makes a really good use case for amoled though. I do prefer LCDs, but ambient display and moto display are features I really really like, and LCDs just kill that for me. I'm on a nexus 6 right now and it seems really accurate, not too warm or over-saturated.
I'm fine with the 6P's amoled screen until I see a LCD again and I get sad. It's a trade off, deep blacks and yellow/pink whites or whites with shallow blacks (although the G4 has impressive blacks for a LCD)
