I was at the Gadget Show Live yesterday and compared the 920 and 820 side by side with the same themes and the same photos. The blacks on the 820 were more darker than the 920 and blended with the black display bezel more. The red tiles were more red on the 820 and more orangey on the 920. I guess this is because the 820 has an amoled screen and the 920 has a tft screen. So despite the drop in resolution (which is hardly noticeable on a 4.3" screen) in my eyes the 820 has a better screen (to the eye) than the 920. Reds are red and blacks are blacker. Interesting.
I guess the Samsung Ativ S would have an even better screen with a Super Amoled display. Hmmm!
Amoled has too much rich colours.It is far behind the reality.IPS of Lumia 920 has more natural colours and better view angels.

IPS panels have better color accuracy than any other technology and that's why they are used in displays demanding accurate color interpretation. I have no idea where you got the idea that the screen was tft, but it's not.
More saturated colors and deeper blacks don't necessarily equal more accurate colors.
IPS FTW. I like Amoled but technology has since advanced. I do like the rich colors in AMOLED but even the Super IPS display on the One X has better natural feel.
As far as I can tell you from my Galaxy S2, the SuperAMOLED wears out VERY quickly! I have a stain where the android status bar is already (after about 6 months)...

Both technology have pros and cons:
Pros for AMOLED:
* deeps black and contrast is infinity.
* more colorful or vivid (can be con for others).
* much faster pixel response time (LCD can't even come close to it even the new 920 LCD).
* No viewing angle limitations.
Cons for AMOLED:
* not as bright as LCD.
* consumes more power when display mostly white screen.
* Colors are not accurate
* Pixel density currently can't match LCDs (the top of line 720p panels are using PenTile to fake the resolutions).
* Burn in is an real issue. Panel life span is around 8000 to 14000 hours.
Pros for LCD:
* Can be very bright. A few times more than AMOLED.
* Accurate color reproduction.
* Power consumption is constant given a back light level regardless of screen pixel color.
* Much higher pixel density than AMOLED without using the PenTile.
* No burn-in. Panel life is as long as the backlight.
Cons for LCD:
* Blacks can't be true black. The best LCD screen can only have true contrast level around 1000:1 (don't trust those marketing numbers using so called dynamic contrast ratios).
* Pixel response time is slow and noticable.
* Viewing angle is not as good as AMOLED. Off angle colors are way off.
The blacks of the 920 are really dark grey - to me anyway.

Hey guys,
Does anyone know if HTC HD2 is a non pentile screen and whether it's not as pixelated as Lumia 800?
The HD2 is a totally different display technology; nothing pentile as far as I remember. Besides that, I think the Lumia 800 screen is gorgeous.

The HD2 has a standard IPS panel, it has the same resolution of the Lumia but it's bigger (4.3"). Basically you can expect some pixelation, weak contrast, bad viewing angles and worse power management. Overall the actually perceived pixelation should be on par, but you're likely to face screen ghosting issues on the HD2. Personally I'm not the greatest fan of Amoled screens, but compared to the unit in the HD2 the one packed by the Lumia wins by far IMHO.
The only big "concern" about the lumia 800 display is the pentile matrix - and the polycarbonate shells that seems not so resistent...

I tried to take a few photos of the HD2 vs the Lumia 800, but it's hard to get my cheap point-n-click to meter well across two such different displays. Seperately, I can get accurate colors on from the HD2, but cannot get good reproduction when taking shots of the Lumia 800.
The obvious difference is Clear Black. The HD2 looks dark gray when it should be black. The Lumia is... well... VERY black.
I personally prefer the way the HD2 shows the Nokia Blue theme. It's more... blue and less turquoisie. Magenta, OTOH, looks much better on the Lumia. It's vibrant and VERY magenta. On the HD2, it just looks like a cheap attempt at bright pink, but slanted toward a flat purple instead. A little too much blue in the display, overall, that lends to great blues and not so great pinks. Whites on the HD2 are cooler as well.
I, personally, don't give a crap about the pentile. I have to think about it and look for it in order to notice it.
The HD2 display will appear more pixelated simply by the decreased pixel density.

I came from an iPhone 4 and I think that we can say anything bad about the iPhone 4 but the display it's gorgeous and the pixel density produce clear and well shaped images, text that cannot be compared w/ the Lumia for obvious reasons but the PENtile display is a punch in the eye - an added one just after the poor resolution imposed by MS -.

As much as I detest Apple products, I agree that the pixel density is amazing.
Looking forward to Apollo, where that can change for WP7 devices for the better.
Thanks a lot guys!
Well I've always thought that the 800 screen would be miles better looking than my 710.
But after picking up a friend's of mine and playing around with it, I find it less satisfying to use than my 710 for some reason.
Some things I've noticed between them.
710 screen flickers(sorta like a those old fashion tv's, ctr or ctf I think). To see it, move your screen around quickly back and forth but don't move your eyes with it. Where the 800 screen doesn't have this. Not a big deal though on the 710 since I usually keep it still when using it.
The thing that threw me off and making me don't like the 800's screen is because there is like a dot of black in between all the pixels. It is really hard to explain it. I think its because of the lack of a backlight on the amoled screens, and there is nothing lighting up the area in between pixels.
I don't know if you guys understand what I am trying to say and if I am high or not but all you need to know is that my 710 screen looks better than the 800 screen even if the blacks are not truly black on the 710's tft, the overall experience on the 710 screen quality is superior to the 800.
It's because the 800 has a screen with pentile matrix. Google it and you will understand what those "dots" between those pixels are. It's simply because there are no "pixel" there. Sort of. The pixel layout differs from a traditional TFT.
What the 800 is superior at though is true black and more natural colors and much better contrast.
To me the 800 screen is far superior becuase of those things alone. Pentile matrix doesn't really bother me and there are a bunch of other phones that has it too. Galaxy Nexus. Samsung SIII to name just a few...

I guess it all comes down to opinions. In my own personal opinion, perfer the tft tonthe amoled. Unless they find a solution to the pentile matrix on the amoled, I won't ever use it lol.
I saw an amoled screen on my friend's galaxy 2 and thought it looked horrible also.
Pentile on Lumia 800 is terrible..
I too was against pentile screens before but I really wanted the 800 and after only a couple of days I was used to it. And ad I said I prefer the deep blacks and the excellent contrast over the extra sharpness.

To be honest I got nothing against TFT lcd panels in general. Colours look way more natural on them and the white is more real. My gf has the 710, so I can make all kinds of comparisons. When you look at pictures there's no contest: the 710 wins hands down: after all pictures have to represent reality, and amoled panels aren't that good at that. Even in the browser gradients of colour are generally kinda messed up on the 800, you don't really notice it until you put them side to side, it's astonishing. Anyway on this particular OS I gotta say that I still prefer amoled over lcd. Using the dark theme on an amoled panel is just awesome on WP7, the metro UI really deserves those deep blacks and punchy colors, with faint blacks this beautiful thing of design is wasted. The 710 may have more real looking colours, it has slightly less pixelation and sure it isn't affected by all of the artifacts that an amoled (especially pentile) unit suffers from, but the viewing angles are kinda poor: the display tends to become yellowish when angled and looks kinda discoloured at the edges. The Lumia 800 truly is a work of art, and its amoled panel is part of its nature: when it's laid on the table at the office and somebody calls you or something it really looks like a living thing. The 710 instead doesn't really draw that much attention, and there's no magic whatsoever when it lights up

iPhone screen is no longer the best anymore. There are a lot of phones at this point has higher PPI than iPhone. In this case, Lumia 920 has more advanced technologies than iPhone. Fast refresh rate (the only 1 that has 60Mhz refresh rate screen), high PPI, ClearBlack for easy reading outside, IPS panel, and also super sensitivity.

Display of Lumia 920 is better of iphone5 in the details?
yes, i'm not sure what other details you want, but in every technical way, the l920's screen is better than the iphone 5. most newer android phones are better in many ways as well.
here's the ways its better:
higher pixel density (text is sharper, images are crisper)
higher refresh rate (images move smoother)
clearblack display (easier to read in sunlight)
supersensitive touch (can use with gloves, fingernails, or anything else that isn't your finger, as well as your finger)

It's a 60Hz display and pretty much every modern smartphone has a 60Hz screen. It's just marketing! As for Clearblack that was for the OLED screen in the 900, this one is IPS and is called PureMotion HD +
As for the screen quality itself I've found the colours are pretty damn good. Waiting for Display Mate to do their analysis though.

I had read somewhere that they had gotten it to 23Hz? I may be wrong though.
They polarized (a layer? of) the screen so that it's easier to read in sunlight.
Also, although it's called PureMotion HD+ and they've dropped the ClearBlack name, they still reference to that type of display technology for darker blacks in comparison to other SLCD2 technologies (ex. HTC 8x/One X)
@OP, just recapping, but....
Better than iPhone because:
Bigger screen (more opinion than anything)
Higher pixel density (332 ppi vs iPhone 5's 326)
Ability to use screen with gloves (i.e. skin contact not required to operate screen)
The screen is essentially better in every way in comparison to the iPhone 5 other than the lamination that the iPhone has (i.e. the screen appears much closer to the surface of the glass itself when compared to the Lumia 920's). If you're REALLY looking into great screens, you should just go to Verizon and pick up their Droid DNA.

Sorry thinking ms. My bad. I remember something about the PureMotion HD+ referring to having the smallest delay between touch and response. I don't know where, but there's a couple articles and stuff referencing it haha. It supposedly has the fastest response times of any screen for a smartphone on the market.
actually the lumia 920 is the first smartphone with a 60hz refresh rate and its response time is in the single digits
just check out some of the more detailed/reputable reviews and it will give you a compare of other brands, i can't recall which ones exactly as i read them in passing
and clearblack is nokias name for their polarization filter on screens

Nope, I don't think every smartphone has 60Hz screen. As for the name, Nokia combine those techs into one and called it PureMotion HD+, which consists of:
1. WXGA resolution
2. IPS LCD with 60Hz refresh
3. ClearBlack technology for viewing outdoor
4. High PPI
5. Super sensitivity touch
So if you take all of them and combine them all, it is PureMotion HD+.
Every smartphone other than the Lumia 920 has a 30Hz screen. The 920 is the first phone with a 60Hz screen.
Clearblack is a combination of a polarizing layer to reduce glare and improve visibility in sunlight and also (iirc) they are also using an optically bonded stack, fuzing the digitizer to the cover glass.

Can you cite this please? This would mean every other phone would look like it's running at 30fps which you would notice. Also clear black was marketing for nokias oled screens.

Yes, and that's the phrase they marketed because that was all they had that was unique to them in the screen department. Now, they use Puremotion HD+, which includes ClearBlack along with a number of other technologies/features, as noted above. Nokia's own developer 920 spec page lists "ClearBlack" in both the description and the list of display technologies.
The screen is simply amazing. It puts any other smartphone screen I have seen to shame in actual real world usage.
This is the first phone I have owned that I can read the screen in the sun, with my sunglasses on. Amazing.
The viewing angles are incredible, the colors are bright and vibrant but not as saturated as AMOLED, and not as dull and lifeless as HTC Screens.

It's funny you mention this because coming from a Dell Venue Pro with an amoled screen that I've used for a year and half, I immediately noticed the terribly dull colors of my 920 screen. Now that I've used my 920 for a few days, I booted up my DVP for giggles and I couldn't help but notice how really overly saturated the colors were! I am truly enjoying my 920's screen as I think it is a good blend between SLCD and Amoled and outdoor viewing really kicks butt on this screen.
The source is from here http://conversations.nokia.com/2012/11/16/how-nokia-gave-the-lumia-920-the-worlds-fastest-screen/ which cites Nokia's Senior Technology Manager. The main take away from this is that the L920 LCD screen has a 9ms pixel response time while others on average is about 23ms. There is no mention of iPhone so we don't know what response time of iPhone screen is.
This is not about 60Hz vs 30Hz. It is about pure pixel response time which is critical in display moving objects in video of games. For comparison, your typical PC desktop LCD monitor need to have < 5ms response time to be comfortable for playing games. 23ms response time is only good for reading emails.
To recap, Nokia's screen has better pixel density than iPhone's retina display. Higher resolution than iPhone5. Maybe faster pixel response time and higher contrast than iPhone (we don't know until someone benchmarked it). Tradditionally, iPhone screens have very high color accuracy. We don't know what Nokia screen has.
I see so much hate for the iPhone here, actually iPhone screen is pretty good they both have 60hz, Lumia has a little higher PPI(but not noticeable) and can be used with gloves, iPhone in its own side has the in cell technology that take away the touch panel and implement it directly in, igzo technology that reduce battery usage.

It is nothing but fan boys citing from their side of marketing BS. I mean both sides. For example, you made it like iPhone5 invented in panel touch implementation. I'm not so sure. Samsung did it with its Super AMOLED Plus screen about two years ago to reduce the screen thickness and sun reflection. Apple probably just re-invented (like many of its claims) for LCD panels.
i got the huawei mate 10 pro specifically for the thin bezels and oled display with no rounded corners or rounded screen and i have to say i absolutely hate the display, it reminds me of the samsung galaxy 4 years ago, the colors are so dull that my Xperia xz1 has noticably crisper more vibrant colors putting them side by side makes the huawei look like a joke where like 50% of it's colors are reduced especially with green, is this due to the preapplied screen protector will there be a big difference if it was removed? frankly i am shocked at how bad this screen is to my Eyes i don't love the screen of the s9+ either most oled panels appear very warm to me i think the note 9 is the only panel that hasn't from the brief experience i had with it but the s9+ is still miles better, i have put the color to as cold as i possibly can but it still appears so warm and yellow, i have my Xperia xz1 set to the extra vibrant mode with blue set to 150 so i prefer cold colors over anything, but seriously the color is so dull on the huawei so dull and dissappointing, the Xperia uses ips the huawei uses oled, ips is not supposed to be crisper and more vibrant.
Uhh you do know there's a color profile option under Display--->Color option right? I suggest checking that out cuz this post is pretty ridiculous
Plus the XZ1 has an HDR display according to the spec sheets so you're comparison to crispness is basically out of whack
Hello RXT Users,
I bought a new Realme XT (6GB,64GB, Pearl White) Mobile, which works like a beast.
But within a week, I accidently noticed that the true deep blacks of Amoled display actually kills the surrounding Grey colour pixels especially in videos (or moving frames).
When I using Instagram, Samsung just posted some photos. when I try to swipe one photo horizontally, I noticed that the gradient colours (White to black) are like vanished some time and and a bluish shade is appearing btw the blacks and whites.
Then I started comparing this with other LCD panel, which is not doing these weird things. I also did a side by side comparison btw Realme XT and other LCD display by playing a dark horror movie. The results came was not expected.
First things first, the picture quality, colours, contrast and viewing angles are awesome in Amoled display, But the grey coloured details which are nearer to the black pixels are missing, they are completely gone.
Example:
• Original frame in the movie - A dark room with cupboards and interior.
• Picture shown in LCD display - white blushed dark room with cupboards and interior.
• Picture shown in Realme XT - A Deep Dark Black room with no interiors no cupboards or even no walls.
I can't understand why the Amoled display takes more time when pixels changes from black to grey colours, may it's because of low refresh rate.
Can anyone please tell the display refresh rate of Realme XT and try the above tests to clarify that I am not the only one who got these weird thing. Thanks in advance.
Note: I am using Amoled display for the first time.
This is quite disturbing to know. I was planning on buying XT and returning my Poco armoured, as it has ghost touch issues and I don't need that much processor power for daily usage.
Also, with XT getting started on development I hope I won't miss Poco. But with the above-mentioned issue, I'm getting skeptical because my primary reason to get XT was AMOLED display. I don't want to get disappointed by it.
Although it doesn't has ambient display and dark mode yet but I hope it'll be there in future updates.

After reading this post I checked my xt's display for the greys in dark scenes with my le 2 LCD display and I'm pretty satisfied. I was able to see most of the details of dark scenes that was visible on the other phone. Plus I found it's very vibrant as compared to the le 2 and brightness level is also much better.
