[Discussion] AMOLEDs are awful. why do you people like it? - General Topics

I'm just gonna say a few things about Samsung's AMOLED displays. people all over the internet say Samsung phones have the best displays.
lets me start by saying a few facts about AMOLED. then tell me why samsung still uses AMOLED instead of IPS or why people like it:
1. AMOLED dipslays have a terrible purple smudge. specially when they switch from black to grey they show a purple tail. this is super annoying. my s7 edge is just unusable.
2. Longevity. they lose brightness and color and change overtime
3. Burn-in
4. Power consumption showing Whites are higher than LCD. and Samsung phones all use white themes at default...
5. Color accuracy. it's nowhere near iPhones IPS. specially with iPhones wider color gamut things look better.
6. Cost more to manufacture.
7. Pentile pattern makes everything look. weird. whites look rainbowish. they need more resolution to achieve the same look sharpness as LCD.
8. They're awful at showing whites.
my Knowledge is based off the internet and eyes. I'm not god I might be wrong.
and remember this is a friendly discussion. not a fight!

I love AMOLED because of the deep blacks. I use the Reddit is Fun app a lot and the true black BG option they have for phones with amoled panels makes it really easy to browse reddit for longer than I should be. It's also nice that when watching media on my phone with black bars on top or on the bottom that they are not lit up with a backlight and blend in with the bezels. I don't think I could use amoled on a laptop or desktop for the reasons you've mentioned, though.

Yeah. but the Purple smearing makes it terrible. watching movies or scrolling is just terrible.

There are positive things too. You can always keep screen on minimum brightness for clock and etc. AMOLED screens look better than IPS LED, their colours are brighter. I don't think that's bad technology as more and more smartphone makers are making transitions to AMOLED screens.

My moto x had an amoled display, and I loved it because of active display. There was pretty much no effect on battery life because of the amoled panel. Also, for those who prefer oversaturated colors, amoled delivers. Also, like it was said above

Replace current Super LCD screen with AMOLED screen

Thanks to xda-developer members we can now confirm SLCD and AMOLED device's screens can be swapped.
Currently the only known way to do this is to replace the whole motherboard.
Because it seems the connectors look the same but will not work when switched to another screen type.
Other ways are yet to be discovered.
I recommend you only to try swap if you really have to, otherwise stick to the one you currently own because the difference isn't that big.
Here I uploaded a pair of instruction videos of assembling and disassembling the device:

'HTC also claims new SLCD displays have “approximately five times better power management” than older LCD technology'.
AMOLED has better viewing angles than LCD & SLCD but LCD/SLCD shows better results in direct sunlight.
you can buy one, but I dont know If it would still work (connectors..)

Quick question: I thought the SLCD's were the better screens between the two types?

who told you that lol amoled has much better colour definition and much better black definition, its also less power hungry
Amoled has awesome contrast and unbelievable dark blacks. In addition the colours are more saturated and look better in general.
HTC had to change to SLCD Panels because Samsung cant produce AMOLED screens fast enough (Samsung needs to produce them for Galaxy S too!).

The AMOLED draws less power when displaying mixed-color and dark images... as soon as about 40% of the screen is white, traditional LCD (and I suppose SLCD even more) is superior in power consumption. In fact, when displaying a page that's mostly white (like black text on white background), AMOLED draws 2x-3x MORE power than LCD.
In addition, the pentile matrix on our Desire AMOLEDs makes text look like it's gone through a meat grinder (jagged edges, not sharp at all), and the colors are all neon-y. Not to mention the pink tint at low brightness...
The SLCD has far more realistic colors, is color-stable at basically all brightnesses and produces sharp text. Oh, and for my use (surfing the web, reading eBooks), it uses a LOT less power.
Check out the Froyo Battery Use thread over in the Desire General forum for more info, there's a ton of background information in there.
But the AMOLED screen stays perfect in heavy sunlight right?
Or do you think I should forget to replace it and just stay with the SLCD.
AMOLED is piss poor in direct sunlight!!

More like the other way around, although tbh the difference is slight.
Well I have done extra research on this. Seems, over all AMOLED is better. SLCD suffers from light bleeding from the edges.
I used my phone in direct sunlight today - wasn't perfect - however I could clearly read the screen and make out the text on it, etc.
If you can, I so go with AMOLED.
Edit: I have yet to notice the pink tint issue? And text looks clear and perfect to me.

Why go with AMOLED? Because you can barely read it in sunlight? Because backlight bleed trumps far lower power consumption, sharp text and realistic colors?

Compare it to screenshots (you can take them directly with the SDK) on your PC and you'll notice right away. All the greys are pink when the brightness is low...
Both have their pros and cons.
The SLCD is sharper, because of RGB Subpixels, has maybe better battery life with white backgrounds. The colors are more natural.
SLCD has a worse contrast (no true black). It also has worse viewing angles. The colors are more natural but less vibrant, and more vibrant colors just look better on a phone, so the colors are worse for me
AMOLED has a super contrast and real black. It has a better battery life with black backgrounds, which most mobile operating systems are optimized for in my opinion (or is the settings dialog white?). The colors are gorgeous. They are very vibrant, which means they don't represent the true color value, but who cares, it just looks better Who has an AMOLED screen? It's something new, unique, something special.
AMOLED is less sharp, because of the pentile cheating, no RGB subpixels.
Pink color: That's because of the pentile technique and is easy to fix with proper color profiles, which was done with the release of Android 2.2. So no visible pink at low brightness any longer.
Sunlight: In the images and videos none of them performed better. Both are readable in direct sunlight. None good.
HTC was forced to change to SLCD.
So both are almost equal. SLCD is a normal display type most phones have.
The only real disadvantage AMOLED has, is the pentile technique.
Else, it's my preferred display type, especially because I just wanted to have an AMOLED screen. The black and the colors are just impressing. I don't care if hte colors are natural or not, they have to look great, which AMOLED colors do. Especially photos look superb.
If I compare the Desire AMOLED display with the AFFS+ (similar to IPS, just better, it's the best you can get on a laptop) Display of my tablet PC, then I see a huge difference in the colors. Sure, the laptop display shows me the true colors, but they just don't look that nice. The black is not as black and the colors, like red, are not that vibrant. It looks somehow boring.
AMOLED was one important reason why I've bought the Desire.

I've always read that a black screen on a LCD display used the most power because every pixel is effectively on (blocking light) while white shown on a LCD uses less power because all the crystals are allowing light through... It would make sense, though, for AMOLED to use more power with white because every pixel is on.
But maybe this only applies to large format displays? (i'll look for sources)
Found quite a few sources just searching google for "LCD use less power with white" (including a scientific american article). But there's a current thread about the n900 where they talk about this specifically: http://talk.maemo.org/archive/index.php/t-59872.html
@Upspin
You're right, of course - both have their upsides. I just don't understand why you'd want your screen to show "unreal" colors. Might look better when you're just looking at the homescreen or icons, but what about watching video or looking at photos? I hate the way people (skin tones) look on my AMOLED Desire
As for battery life, there really is no contest when it comes to things like web browsing. Since most web sites use dark text on bright backgrounds, the power consumption with AMOLED displays goes through the roof... CyanogenMod has added color inversion to the browser to help, but that makes the scrolling in the browser choppy, and I like Dolphin HD

You just have to understand how a LC and an AMOLED Display work. Both work totally different.
On an AMOLED each pixel emits light on their own. Thus, dark pixels consume zero energy, red 1/3, green 1/3, blue 1/3 and white all of them combined. With the pentile technique it's not 3*1/3, but a bit different, not that important.
A LC, just as the name implies, consists of Liquid Crystals. The easiest structure is TN (Twisted Nematic). The principle is simple. You have a white background source, which consists of blue, red and green light. Together it appears white, easy. This background light is on, the whole time, regardless if you display black or white content on the display. But how do we get colors and black and white? Now you just have to place a (1) polarizer, (2) an array of Liquid Crystals, and a (3) second polarizer, which is rotated by 90 degree in relation to the first, in front of this light source.
To keep it easy we use a TN structure.
Without any voltage applied to our LC, the light from the background source passes the (1) first polarizer and gets linearly polarized. Then it passes the (2) LC, gets rotated by 90 degree by the twisted molecules and passes the second polarizer, and you see white light.
With voltage applied, the molecules in the LC get rotated, so they aren't twisted any longer. Now light passes the first polarizer and gets polarized again, passes the LC without getting rotated this time, thus gets blocked by the second polarizer and it appears black to you.
So finally:
A LCD has an always on background light. However, black needs more power because you have to apply a voltage to a liquid crystal, and a leakage current causes the power draw. White however needs less power, because you don't have to apply any voltage.
However, I think this effect gets really interesting if you have large displays or a high number of pixels.
Several magnitudes more power consuming is the background light.

Yup, true. I have to life with this drawback. Not that huge in my opinion, because battery life is fine for me. I recharge every day, regardless how full/empty my desire is, so really, I don't care that much if it consumes a bit more or less.
But nice tip with the color inversion mod, great for night browsing.

I need all the battery life I can get - almost never make it through a full day
I'll just stay with the SLCD if it doesn't make a really big difference anyway.
Recharging your phone every day? I always wait till the battery is drained almost completely then recharge till 100% full because that is supposed to be better for your battery.
Might just add a poll just to see ratings between what favors people the most hehe.

AMOLED vs LCD vs TFT

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,....

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).

Amoled vs LCD ...The truth? Video inside

Since lots of users like to compare phones that didn't even hit the shops yet, or are not even officially launched , why not compare other related stuff? :
I find this recent Erica Griffin's video which is called "the truth about Amoled vs LCD" quite interesting:
I stick with Amoled anytime, even with the possibility of that "blue pixel burn-in"
Edit:
And here some interesting related info provided (once again) by Barry:

Good news for the reviewer! She can buy AMOLED again if she wants to. Starting with the SGS4 Samsung's moved to a new PenTile geometry called Diamond Pixels.

A high resolution screen shot of the Galaxy S4*(provided by Samsung) shows an interesting design and sub-pixel arrangement, which Samsung callsDiamond Pixels. First of all, the Red, Green, and Blue sub-pixels have very different sizes – Blue is by far the largest because it has the lowest efficiency, and Green is by far the smallest because it has the highest efficiency. The alternating Red and Blue sub-pixel PenTile arrangement discussed above leads to a 45 degree diagonal symmetry in the sub-pixel layout. Then, in order to maximize the sub-pixel packing and achieve the highest possible PPI, that leads to diamond rather than square or stripe shaped Red and Blue sub-pixels. But not for the Green sub-pixels, which are oval shaped because they are squeezed between two much larger and different sized Red and Blue sub-pixels. It’s display art…​

I only buy Samsung because of the AMOLED screens.
it's true there will eventually be some bluish pixel burn-in after you have used the phone for a good 3 or more years
and it doesn't seem to affect all AMOLED screens, but specific to the 5 color ones, the S-AMOLED seems unaffected by it.
I'm basing that from my old AMOLED i9000 and Nexus S vs. the S-AMOLED on the S2
As for color accuracy, I like the more vivid color provided by the AMOLED than the LCD / S-LCD
Interesting stuff. My next phone gonna be LCD.

even after learning what they do to the LCD displays?
you will probably have to run your own tests to see which phone has a correct LCD display, or waiting until some one has done a Gamut color level review on it before getting one.
at least with AMOLED you know what to expect.
I will not go into fight any about this, but after using both AMOLED and LCD, I simply don't find LCD 'interesting'.
But if we really want to go deep into technical analysis, you will find that a AMOLED display is considered to be the best display commercially available now. Check Samsung's new OLED TV KN55S9C reviews. Every reviews (including consumer reports) have mentioned that this has the best picture quality available right now.
I am going to be honest here and put my hands up and say I was not aware OLED screens are still affected by burn-in - but it makes sense.
I think I am going to cancel my pre-order of the Note 3, things like this really put me off - I love my nexus 4 screen and I think I may now wait out the Nexus 5 which will in all likelihood have IPS.
My last 4 devices were all with Amoled S and N series and never had such issues.
You really have to stay a loooooong time on one screen position to then, only increase a chance of blueish burn-in......... I guess

Yeah, screens have come a long way since even my galaxy nexus, which I didn't like it always looked greenish to me. But I played with a note 2 and that screen is great, the gs4 is even better, screens are largely a personal preference but give me true black any day
Interesting find. Gonna have to look for something to replace all the JellyBean blues on the new phone to ensure longevity. Tbh I haven't noticed anything on my current 1.5 yr old amoled phone or the 3 yr old phone before that. But I have noticed how much I enjoy the color, over saturated or not. An Apple genius bar friend had severe screen envy when he saw the size and colors lol.
Only downside has been viewability in sunlight to where I have to drag brightness all the way up to get a decent picture.

Regardless of what the sales and marketing terms are, the simple fact is all current and future Samsung devices have made the switch to "Super AMOLED" based panels so do not concern yourself with any BLED burn-in. This so-called issue was addressed several generations ago when AMOLED was still under testing and Samsung is among the best when it comes to yield/performance.
With that said, both the Samsung and T-Mobile sites show the final NS3 specs, which includes the use of their "Super AMOLED Display".
All is good and here in San Diego, CA, both T-Mobile and Verizon retail stores are sticking with October 1st and 2nd (respectively) as the official release.

Who said saturation is bad? And when did wide colour gamut become a bad thing? Even with a wider gamut, AMOLED still can't cover full range of visible colour space. Even if someone pushes to Adobe RGB or NTSC colour space, I think its good.
AMOLED covers more green-yellow-cyan range. Remember that the eye is more sensitive to yellowish-green light than other colors. G2 is over-saturating the colours, but it can't show additional colours like AMOLED as it's inherently restricted to show just near sRGB space. Why restrict ourself to sRGB when it was designed for CRT monitors?? But the fact remains that AMOLED can show more colours compared to LCD. And that's a good thing.
Reviews have proved that the best available display right now is OLED display. Samsung's OLED TV KN55S9C is considered to have the best picture quality. Saying AMOLED is bad is pure non-sense.

Here's my opinion. I could give a crap whether a device I want to purchase has AMOLED or LCD. All I want is a good high quality display. There are crappy LCD displays (there are tons of posts in the One and Z1 forums about display issues) and crappy AMOLED displays. Truthfully, on a 4.7-6" canvas the amount of energy devoted to examining nuances in displays is comical. AMOLED has far superior contrast, bolder colors, better reflectance, better viewing angles and uses less energy on dark colors. LCD produces truer colors (depending on OEM calibration choices), is brighter, and uses less energy on light colors. The hardest part of going from AMOLED to LCD for me is the drop in contrast and greyish blacks which are unavoidable. If the N3 had a high quality LCD display I'd be totally fine with it. More important than the display is what it's attached to and I happen to be happy with Samsung's products. I'm not buying a display; I'm buying the high-end mobile device it's a component of. And the displays in Sony and HTC's phones are all made by Sharp-Renasys or JDI anyway.
And as you ridicule AMOLED, ask yourself why Motorola (Google) used it in the Moto X which is the most important phone they've ever released.
Like LCD? Bully, buy a LCD-equipped phone. Like AMOLED, buy a phone that has it. If you're happy I'm happy for you.

Contrast (true blacks)

How well do you know your fifty shades of grey? Rate this thread to express how good the Huawei Nexus 6P's display contrast is. A higher rating indicates that black is true black, rather than a very dark gray.
Then, drop a comment if you have anything to add!
Great contrast thanks to AMOLED
It gets backly black as if the screen was off exactly like other OLED displays I've used(S4, Note 4, S6)

Actually, in real world usage blacks are pretty poor/washed out, unless you're in a dark room. When the screen is off you can see the surface of the screen is much lighter than, say, Samsung AMOLED phones. It's more like greenish dark grey rather than black so even if the actual pixels are turned off, it doesn't look black. It's even worse than many LCDs. I have no idea how come no one has mentioned this in any reviews, or at least I've never seen it.

ROFL are you hallucinating? My 6P's blacks are pitch black. The way I can tell... The edge of the screen, when black, is equal to the blacks on the top and bottom of the screen.

Except that is not true. Take a look at the screen when it is turned off. The surrounding bezel is truly black but the screen itself is greenish gray, meaning blacks are not getting darker than that. Then look at a Samsung AMOLED phone and you'll see it's the other way around, it's the screen itself that is as black as it gets. Samsung obviously uses different filters/polarizers which result in much better blacks in anything other than total darkness. I just compared my 6P to an old Galaxy S2 and again, the S2 has much deeper blacks thanks to the actual surface being much darker. You only really get true pitch black when you're using the 6P in a dark room. Otherwise blacks are pretty much on par with your average LCD, which is a poor result for an AMOLED screen.

Well, it's true on mine. Maybe your panel is different then mine. I just compared my 6P to my Note 4 and they look the same. Which makes sense since Huawei buys there panels from Samsung so they are the same panels. Only difference is Samsung panels get a few nits brighter.
Guess we can agree to disagree. Especially since you can get different quality panels from phone to phone. Just like that can happen on Samsung phones.
Oh and I forgot, there are no filters to make blacks, black as you don't filter light on Amoled screens. The pixel just doesn't receive power so the pixel is off, not filtered. What you are referring to is an LCD panel, not Amoled

It has nothing to do with pixels being off. Look here https://technology.ihs.com/509943/w...izer-technology-trend-of-amoled-use-polarizer
Remember the first Nexus, the Nexus One? It also had an amoled screen, with terrible blacks. How was that possible? Because the actual surface of the screen was so reflective, if there was even a little bit of ambient light reaching the screen it would completely wash it out. Whether the actual pixels emitted any light was irrelevant in any other conditions other than complete darkness.
There are no different panels being used on the 6P. Just take the phone out of a dark room and you'll see the screen is clearly not as black as the bezels when it's turned off. I have so far compared it to the following phones: Note 5, S6 edge, S4, S4 mini, S2. All of them have deeper blacks than the 6P due to their surface being darker. It may be a Samsung panel but it's not the same one as used by Samsung on their devices. Even Anandtech have mentioned it uses different lamination which actually provides slightly better viewing angles. What's strange is that the more off angle you go, the lighter the surface appears. Can be seen in this video comparing the 6P to the 5X http://www.youtube.com/watch?v=GXtDCBSKQV8&t=3m44s Obviously it's not as bad when looking head on but it's still pretty poor for an amoled screen.

Hmmm sorry man mine is just black. Agree to disagree. Can't say any better then that. I'm moving on. If your not happy with the phone for that reason, sell it and get a Samsung.
Well, it was nice discussing with you but one may as well say "mine is pink, agree to disagree". It doesn't really mean anything as far as facts go.
I just took out my old Nexus 5 and surprise surprise, it absolutely kills the 6P when it comes to black depth in well lit conditions. The surface of the screen simply reflects way too much light.
Hahaha so many people here producing disinformations...
AMOLED, especiall Super, has 0.098% of light coming thru when fully black but on. That's the blackest as it gets.
6P, Note's, S6, S7. have the BEST SCREENS around. And by far.
Turn on sRGB mode in developer options if u want, a bit washed, but 100% accurate colors. What u see is what u get on print. But why would u use that, unless you're a professional photographer like me.

Coming through what? Screen surface reflectiveness is what matters the most when it comes to black depth outdoors. LCDs have extremely high MEASURED black levels in comparison to AMOLED but you can't see that outside because of ambient light. Case in point, the 6P looks worse than most good LCDs outside. It's like when people claim plasma TVs have amazing blacks but forget to mention that is only true in low light conditions.
Jockson I understand and agree with you. The screen on the 6P has a lighter surface color than the black bezels above and below which is noticeable. It isn't a major detractor from the visual quality screen on, but I agree that in a bright setting, blacks don't get to be as black as could be. It isn't bad by any means, but unless you get a completely black unreflective layer it may not be easy to improve (or Samsung is hogging it all to themselves).
Either way, you're right though the quality of the screen is still really good on the 6P so, yea. Still like my 6P, even after using a HTC 10 with it for the past 6 months. Both great, but the 6P has me returning to it more, for now.
Finally someone understands what I'm talking about. I don't want to "sell this phone and buy a Samsung then". I already had the Note 5 and got rid of it for the 6P. Love this phone, love the screen as well in low light conditions. But this really caught me by surprise. I've switched to a full black theme and outside, it really shows how washed out it really is. On a cloudy day outside, blacks on the Note 5 look almost perfectly black and yet the 6P next to it looks horribly washed out and more like greenish grey. I knew it wouldn't compete with the Note 5 in direct sunlight but it's pretty disappointing that it loses out considerably in medium light conditions as well. And not only to the Note 5 but to the ancient S2 as well. The display surface just doesn't look like any Samsung amoled phone ever which is pretty strange.

I agree with this completely. It's pretty hard not to notice that there is a definite green/brown tint to the display in contrast to the surrounding black bezel when in good ambient light. I came from a Nexus 4 and I was immediately disappointed by this aspect of the 6P display. Since then I have reconciled this disappointment with the fact that the 6P is overall a fantastic phone with substantially better value than other premium phones.
I'm not 100% sure that it's much better on Samsung devices because Samsung goes out of its way to mask this issue by making the top and bottom bezels of their phones different (non-black) colors. I'll even go so far as to suggest that the curved display on the Edge was a gimmicky attempt to obscure this issue. This, among others, is an AMOLED problem and why Apple hasn't used them. Still love the 6P, especially now on Nougat.
You are absolutely right regarding Samsung making their bezels non black. Even on their black phones bezels are often very, very dark grey. But still, their screens do have far less reflective surface. I wasn't really sure myself was it such a big difference until I compared it side by side with the Note 5, S6 edge and S2. The 6P just looks green and very washed out in comparison.
People often forget it's the perception of contrast that matters, not the absolute measured black level. LCD often gets criticized for poor contrast but visually it has deeper blacks than plasma and CRT do, except in low ambient light. Same story with the 6P. Great blacks when there isn't much light around, otherwise pretty poor and washed out.

Well yes if the screen is off and you're in sunlight, you can see the difference from the bezel. That's normal for every phone. I rarely use my phone in direct sunlight. I'm talking about normal use and when the screen is on, I can not tell the difference if say the status bar is black and the edge/top/bottom of the bezel. So if you're just talking about screen off and in bright light/sunlight.... that's every phone basically. But I don't stare at my phone and worry about how dark the screen is when it's off.

How dark the screen is when it is turned off IS what the blacks actually look like. It can't look any darker than that, the screen doesn't emit the "black" color When there is bright content on the screen it just tricks your eyes/brain into thinking black areas are darker than they really are but in reality, contrast is still pretty poor.
I'm not talking about direct sunlight either. Even in medium ambient light blacks wash out considerably. Certainly MUCH more than they do on Samsung AMOLED phones and most LCDs so no, not every phone is the same. The 6P display just isn't very good in this regard.

Previous phone was Galaxy S8, I don't find much of the experience difference.
IPS LCD and AMOLED displays has advantages and disadvantages
IPS LCD has that AMOLED doesn't have:
-Sharpness and Clarity is good
-Natural Colors (AMOLED is little saturated on Colors)
-Can recover to accidental burns or screen burns (AMOLED cannot recover on screen burns thus leaving white marks)
-Longer pixel life (AMOLED's pixel quality degrades over time)
AMOLED has that IPS LCD doesn't have:
-Improve battery life as turning off pixels without backlight (Good for Dark Themed apps, videos, photos)
-Brightness and Contrast is good
-Good Viewing angles
-Always-on Display (IPS LCD cannot support this due that it uses backlight rather than turning off black pixels thus increasing power consumption)
Verdict:
No clear winner. It is the preference of both users and the manufacturer on what type of display they want to use. This is why Xiaomi uses IPS LCD Displays because it is cheaper than AMOLED ones. The target is being a budget flagship-tier phone thus achieving it.

Yeah best done with a gray picture so you can see the burn in on the oled. After some burned oled I only buy IPS screens.
I can't understand the "true black" hype as there is no such thing in real life and as the brain even can interpret white as black if the contrast is right.
As long as OLED tends to burn in, it's a no-go for me.

Three reasons why Xiaomi should go the OLED route :
True black :
Here's an example of true black :
On you Poco, go to full screen settings and turn off the notch. Now to two top corners are rounded as the bottom ones. Now go to a dark room, as if you were using your phone at night. Well you still see the top corners of your phone's screen on. Of course that color is black, but it's awful. (In a dark room you see it better, but I see it in the sun as well).
Always-On-Display or AOD :
You can't have AOD on an ips panel. End of the story.
Brightness :
Outside in full daylight, I constantly have to block sunlight off the screen and put it right up to my face to see what's on it. OLED is way brighter.
Bonus :
Dark mode is here in the MIUI beta and coming to everyone later. MIUI 11 will have it out of the box. This means phones with OLED screens will have a great battery advantage over ips.
Also - OLED and AMOLED tend to use very low PWM which may give you a headache/migraine.
For instance - Xiaomi Mi 8 with AMOLED panel has backlight that flickers at 100 Hz, Samsung S9+ has AMOLED panel with backlight that flickers at 215.5 Hz while Pocophone has a backlight that flickers at 2315 Hz (source - notebookcheck reviews)

Lo. I wonder if you have ever used a Samsung device with sAMOLED display? Just place both a sAMOLED and a LCD display side by side and see the difference.

They have pros and cons, both of them. While sAMOLED has better contrast, black colour, and often better viewing angles, IPS has most of the time better colour accuracy and it's better to look at while exposed to direct sunlight. I mean, you use the one which suits you the best. Unfortunately, Xiaomi uses probably some cheat IPS panels, so they look worse compared to some higher end phone with IPS panels.
True black is just an excuse ??
And amoled panels aren't bad or anything. They are just over rated and people say. Amoled- amoled l. Look it's not that a big of a deal.
And battery consumption difference is just minor
Like 3 or 4% through dark mode in amoleds too
So what's the hype
I just said Poco-f1 LCD panel is just as good as OLED
If not it's only a difference of 19-20
Nothing more
Ill always prefer lcd. When i bought the phone i had to keep it on over night for data transfer via wifi as i had no pc , to keep the wifi transfer app alive i had to keep screen timeout to never, on morning i noticed lcd retention all over the screen ?(similar to amoled burn in but not permanent), had it been an amoled surely my screen would have to be replaced day 2 of buying a new phone. I had to use the phone screen a lot but the Lcd retention went away completely after around 8 hrs:victory:, so no amoled ever unless they fix burn in!
lol this thread is like a circlejerk. my poco f1 has crappier display than my a2. it has the lowest quality lcd possible. this comes from someone who has used over 37 android smartphones throughout this decade with many being top tier flagships.
But poco F1 has a comparatively dim display even for an LCD. Under heavy sunlight it becomes difficult to see the display. On S10 for example you can clearly see it in any condition. That is why they bumped up the brightness in the poco X2
