It's AMOLED with 120Hz
But the new display has more brightness even at low light condition, that's why some OEMs introduced the Low Brightness Mode

I don't understand how it will be amoled with 120hz and LCD with 60, mentioning what you say about the low brightness mode, even so it backlights and with 120hz it also lights up

Where I say that it's a LCD?
I say that is an AMOLED with 120Hz of Refresh Rate
Samsung adopted a Mode to lower even more the brightness during night.
That not means it's a LCD.. it is always an AMOLED

Just curious, anybody know what the contrast ratio is on theses phones?

Nearly infinite since OLEDs can achieve very bright whites and black levels of near zero, so low that instruments can't even measure it.

is there a difference between amoled and oled?

Yes and no, amoled is a specific type of oled display. An amoled display is always an oled display, but an oled may or may not be an amoled.

Not really. AMOLED just mean Active Matrix Organic Light Emitting Diode. An OLED is an Organic Light Emitting Diode, and can either have an active or passive matrix. The AM in front of OLED is uselessly tacked on. LCDs are usually active matrix and no one calls them AMLCDs. It's just marketing BS.

One of my main applications is to use my phone as a GPS in the car. Screen readability in bright conditions is therefore key. Popular wisdom is that AMOLED screens, whilst offering better contrast than LCD, are dimmer. This could be a deal breaker for me with the S3, especially as one of the comments in one of the launch video blogs mentioned a 'no so bright screen'.
How have others found AMOLED screens of the type used used in the S3 in bright conditions?
amoled does have lesser brightness ,have seen in on my sgs2 but its clearly readable and usable in direct sunlight
and also if you see the brighntess test values from gsmarena sgs3 has better brightness than sgs2 , so it should not be a problem

All I could find was this
http://www.gsmarena.com/samsung_galaxy_s_iii-review-757p2.php
@100% brightness SII = 330 cd/m2, SII = 362 cd/m2, so it looks like the SIII is worse unless I misread something. Looks like HTC One X is king in this respect, but will have to wait for GSMarena sunlight legibility test

oops i meant g nexus and not s2, one x is lcd so it will have the brightness
LCD screens do have more brightness because they have a dedicated backlight which is always on and of course produces more brightness than the self-light-emitting subpixels of an AMOLED screen.
but the sunlight readability is not 1 to 1 derived from the maximum brightness
Galaxy Nexus had a very dim screen i hated it... i hope s3 will have a better screen because it has some changes in the pentile matrix + White, cd/m2 330(100% brightness) and gnex has: 247 White, cd/m2
i had galaxy nexus and galaxy s 3 neither of them bright galaxy s3 slightly betteri think ips screen much better
I've been using a nook color for some time and one thing I really like is the screen.
How would you guys say the Galaxy 5 compares in screen quality?
Colors/Viewing Angles?
Regards,
Mike
Bright colors, good viewing angles, bad resolution. Everything looks blown up, so I change the DPI to 200, but that breaks Google Play, so I install everything before change it.
Sent from my YP-G70
The screen is a VA type not IPS as in the Nook. The Nook has the better screen.
That's not to say that VA is bad but it does suffer from some washout of the color and a slight tint change at wide angles. In any event VA is *much* better than TN.
Also, I think, SCLCD is better, then AMOLED (In SGS+ and SGSII), because SCLCD has much better viewing angles and have not an inversion of colors or "rainbow" effect on the screen. And, for me, it has better colors, excluding black, of cource. IPS has "true" black, TFT is not as good, as SCLCD. So, if you prefer a good screen, IPS is better, next SCLCD. In 4.2 IPS screen, in 4.0 SCLCD, in 5.0 and 3.6 - TFT. But, all features considered, I think that 4.0 is better, than other (in 4.2 2mpx camera w/o AF).
P.S. Sorry for my bad English (^__^)
Are u sure that opx is true black amoled??
What if I say you ... that ..It has a backlight ..
Wanna verify?
Important: make sure u have brightness slider to near low levels. This backlight is not seen at high brightness levels.
Download a gallery like quickpic that lets u open a picture in Fullscreen mode so that picture fills entire screen.
Make a bmp image in ms paint in windows and fill it with perfect black. Or download from some website with hex value coding -enter zero for all numbers
Now load this picture in quickpic or any other Fullscreen gallery.
Switch off every light in ur room .make d room jet dark
Wait a few seconds for your eyes to adapt to darkness
U will see the backlight instead of black.
For more easy recognition see in peripheral field of vision, where low light vision is good. (Focus point of eye doesn't have low light vision ,am a doc.) (see somewhere else, bring in the phone into vision filed)
If u think the gallery is d problem.
Do this same thing in any other amoled phone. You will know the meaning of black.
(I did in Moto x ghost )
It's not a backlight. No AMOLED screen uses a backlight. That would defeat the whole purpose of AMOLED.
What happens is, even if the pixels are black (switched off), they are fed a tiny amount of voltage from the motherboard to allow quick switching of colors so they are never completely turned off. As a result, even when displaying black they emit a very faint glow.
I'm not sure if this only happens on pentile displays (like the one in the OPX and most Samsung phones) and I can't verify since the only AMOLED devices I own are pentile, but my Galaxy S3 Neo also has this "problem". Personally I wouldn't worry too much about it, since even with the glow the blacks are WAY deeper than any LCD display with a backlight can produce.

Thank God man.
I thought my phone is fake display.
Ur reply is proof that knowledge helps..
Btw just curious.. what are you?? How do you know this information not available in internet... So nice to see you man.
And regarding ur doubt, whether this happens in non pentile array amoled ...
NO.
I own a RGB amoled -Moto x ghost phone. It doesn't happen there.
I will check in moto x droid turbo . My cousin has it. So I will do and post results here.
And I wish to add this :
A 312 ppi RGB amoled (I have moto x ghost, 720p, 4.7 inch) is way better much much better than 440 ppi pentile amoled ( I have opx, full HD 5inch)
If I compare the images, they are much cleaner and sharper than opx . It's like the image has a depth, there is some stillness kind of feel. ...( I use colour control kcal, and so I test the displays in many settings not just default.
For example to make the images look similar as moto x ghost so that we can compare, I use rgb values as 32, 30, 27 value at 123, contrast at 121 and then slide the brightness slider to 3/4 or more.
Now both images look same in terms of how much dark areas are visible , the white wash noted in opx is now gone.
Now the images are ready for comparision.
Now the difference is the sharpness or clarity in rgb amoled. The feel difference i get is that there is depth in RGB. Its has a grip.
You don't want to give your significant other yet another reason to yell at you while you're reading XDA in bed. Rate this thread to express what you think of the Realme X2 Pro's display minimum dimness. A higher rating indicates that the display can get extremely dim, ideal for reading in very dark environments.
Then, drop a comment if you have anything to add!
I heard from two people at least there's a problem with this phone that it has visible greenish tint on lowest brightness. Is that true. They said it's a widespread problem...

Confirmed. Sent mine back for this reason.
I can confirm this is a problem when display is low brightness. But if Flicker-Free mode is turned on the tint disappears completely. And the colours change just a little bit (only when display is low brightness), and not in a bad way. It makes white more natural. I will keep it.
It's an issue due to how amoled display's lower the brightness

Let me correct, other 60Hz amoled do not have this issue.
Rest all high refresh rate have this viz. Rog II, Pixel 4/Xl, 1+7T/pro, etc.
Salut, frère. J'ai une question svp. J'aime ce téléphone avec toutes les recherches que j'ai sur Internet et par le biais de critiques YouTube. Ma question est est-ce que je vais l'acheter? J'aime vraiment ce téléphone. Je prévois de le commander ce soir.
Merci beaucoup !
good minimum brightness
It looks like the minimum brightness is on the same level with my old Moto G4+, which seems to have a minimum brightness of 25 cd/m².
But I can confirm a greenish tint (but I think it's not only in low brightness but in all brightness levels, just less visible with higher brightness). It doesn't make a difference if I activate DC-Dimming ("flicker free low brightness" or so) or not. And it's also visible in cold as well as in warm display color temperature. I use 90 Hz.

Yes they do... I've personally seen it on 1x S10, 2x S10 plus, 2x note 10 plus, 1x X2 pro, 1x op7t and recently on the galaxy tab 6. I've also seen people say they have it on mi9t pro and iPhone X.
Edit: Believe me this is a wide spread issue among Samsung oleds... I'm not saying every single person has the issue... But I definitely think most do but don't notice or don't know what to look for. There's no way that it's a minority when I've had 2x S10 plus and the X2 pro and my brother 2x note 10 plus aswell as tab 6 and his partner standard s10 and all have a green tint just to different degrees..
Edit: I'd also like to say it's not limited to region or batch... The first S10 plus I had was from Argos UK, the second from eBay and it was a Hong Kong snap dragon version, my brother's note 10 plus both was eBay, his partner standard s10 was if I remember bought from EE when the S10 range first came out.

So, those who were able to spot green tint, must apply for replacement then.
Well yes if it bothers them enough... Although good look getting a screen without this as my above message it's been on them all... As far as I'm concerned it's probably on most if not all recent Samsung panels... That's not me calling people who say they don't have it a lier... I just don't think they have tested enough... It's slightly different on each panel.
Just to add to this I've seen a mi9t pro tonight with the green tint.

You probably saw it on someones Mi 9T Pro who overclocked screen to 81Hz or 90Hz because on default 60Hz Mi 9T Pro have perfect display. You also said that you saw it on 1x S10, 2x S10 plus, 2x note 10 plus, 1x X2 pro, 1x op7t. Well guess what, I also saw that phones and they have perfect display.
Don't talk bad things about other phones if you have issues on your phone.
X2 Pro is really great phone but most of them have some issues with display because Realme had to cut somewhere to give phone with this specs for very low price so they ordered lowest quality amoled from Samsung.

Don't tell me what I saw or didn't or make out I'm talking rubbish.. the s10 is my brother's partner... The 2 note 10s plus was my brother and the 2x S10 plus was mine... The mi9t pro is also my brother's and he only received it yesterday no screen overclock.
Little update regarding the mi9t pro... My brother got the phone replaced due to heating issues... The new one has less green hue over grey but is still there but this time grey is not uniform and lighter or darker on certain areas and this gets worse when brightness is lower.
This comment is pure speculation.
"Realme had to cut somewhere to give phone with this specs for very low price so they ordered lowest quality amoled from Samsung."
I've attached a photo of my brother's first note 10 plus and I'll have a look later if I can find anymore... He actually posted this on Sam community.
https://ibb.co/Bj0HBzZ
I've attached a good image for others to test... Download the image and double tap in the gallery to expand to full screen... Slowly adjust your brightness while checking the image... This on mine is hard to see any issues unless in a full dark room with no light.

Makes a small difference but the 90hz is not the problem... As I said above with the other phones of which most are 60hz.
Edit 17/04
Pixel 4XL, S10 lite, a71, s20s showing to have this aswell... Like I said previously this is a wide spread Samsung panel issue.
