[PIC] SLCD vs AMOLED

Here is a small picture to give you some information about the differences between SLCD and AMOLED. The AMOLED phone is mine and the SLCD phone is my friend's. Both use identical wallpaper and are set to 100% brightness.

Contrast and saturation of the SLCD screen was terrible compared to the AMOLED phone. It was actually even worse than what it looks like in the picture.
We didn't do any real testing, just this quick photo. Hope it's some use for someone.

I've found it quite interesting reading about this as I bought my Desire second hand today and wondered which I have.
Its on orange so there is no specification on the box as its plastered with orange stuff lol, but i'm pretty sure I have AMOLED from what I have read.
I watched a video where when using the camera in the dark with an SLCD display, you can see an awful lot of backlight bleeding around the edges of the screen so the camera image on the display doesn't look totally black if that makes sense. Have you tried that with your friends?

Oh yes. I haven't witnessed it myself but my friend said the screen has lot's of backlight bleeding. He said he noticed it the moment he turned the phone on for the first time. My AMOLED version doesn't seem to have any kind of backlight bleeding as far as I can tell.

Iv used both types f screens and i heard 50% of people say slcd is better, but when i used them that wasn't the case, the amoled was better...

No neither does mine. I think if i'm correct in what I have read (i'm still learning lol), AMOLED is not back lit as its LED unlike LCD displays.
I've gone in to bootloader, if thats the correct term (hold volume button down and switch on), and my device is dated march 2010 so I guess that would quite confidently confirm my device has an AMOLED display as I believe HTC have only started using SLCD displays recently?
EDIT: Just read through this thread discussing it here but no comparrison pics

I have the SLCD version and I am quite pleased that I did. In the store when looking for phones I was a bit disappointed with the way small fonts looked on the amoled screen, the fonts looked very smudges or dirty on the edges whereas SLCD look crisp and sharp (also on the amoled screen I can make out individual subpixels whereas I can't on the SLCD screen). Maybe the amoled version has brighter colors or a blacker black but in everyday use (well when you use it to read text anyway) the SLCD screen is superior.

My thoughts on the Galaxy Nexus

Hello. Thought I'd add my thoughts into the mix, kind of a mini-review but not very well written and missing lots of things.
The hardware is awesome. The screen really is amazing, and in particular I like the way that it displays blacks so well. Because of this you usually can't see the edges of the screen and it looks fantastic, and coupled with the lack of hardware buttons the front of the phone is really sexy. The back on the other hand isn't as impressive, but it's ok. The "hyperskin" is more hyperbole, and doesn't really help you grip the phone much. Overall it's quite slippy really and I do feel I'll probably end up dropping it sooner or later.
The processor seems to handle everything fine and keep everything running smoothly. GPU I haven't really tested with any 3d games so can't comment on that. Battery life I've found much better than I expected, although I haven't done extensive testing on this. Here are the current battery stats, 18 1/2 hours with about 13% left:

}
I haven't really tried out the camera yet so can't comment on that. Call quality is good. Oh and size, I find it a bit awkward sometimes to pull the notification bar down or to hit the back button in the top left of the screen, ie. in the market app but overall I find the size to be good (I have quite small hands). The light weight and thinness kind of make up for the large size.
In terms of software it's as you'd probably expect - awesome. Face unlock doesn't work well in low-light which is kind of annoying. I'm not sure if I'll keep using it but I like it as on my old phone I only used swipe-to-unlock, so it's a bit more secure with this. I'm not exactly worried about someone taking a picture of me and then robbing me anyway.
The hardware acceleration makes a huge difference. The UI is nice and fluid and it's just really enjoyable to use. There is also an option to force hardware acceleration for apps as well which makes a big difference too. For example Twitter was a bit jerky and laggy before enabling it, yet with it on it's perfectly smooth and fluid. The News and Weather widget however doesn't seem to be accelerated; it's really jerky and slow.
Auto-brightness is something that needs tweaking I think. It's often too low (to save battery no doubt), and needs to be raised a little. On top of that sometimes it doesn't even seem to work properly. Earlier on I was looking at it and thinking how it's too dark and then it suddenly jumped up to a decent level of brightness, even with no change in the ambient lighting. I've seen this a few times so I think maybe it's a bug which needs to be ironed out.
The people app is really brilliant, and the G+ integration is really great (if only more of my friends used it..). The swiping thing they've got going on now in various apps is really good and hopefully we'll see more of it in the future. The dialler app is nice, but I am disappointed that you still can't start typing the letters of your friend's name to bring them up like you can on HTC phones.
That's everything I can think of for now, but overall I love the Galaxy Nexus

[Q] Would this qualify as defective?

My screen shows banding on screens with gradients, like the call log screen, or screens with certain colors, like when I'm playing wordfeud. Even when I'm browsing the white background has faint horizontal and vertical lines.
All of this is only visible when on the lowest brightness setting. So when I'm browsing in bed at night etc it's really annoying.
I went to the (3) store here in denmark, but because it was a well lit room, the problem was barely visible and they said they'd have to send it in for "assesment", and best if i could come back in January and send it in (for 2-3 weeks). I'm just afraid they'll just return it with "problem not found"
I DID manage to report the problem to them on the 14th day after i bought it, their own DOA limit, but I've got a feeling I'm going to get screwed. Especially because the in store phone ALSO seemed to show the same color banding on the call log background.
I've tried taking some pictures that maximize the problem here: http://imgur.com/a/CbKYi#9
Are you guys seeing the same thing on any of your devices?
I love the phone to death otherwise, but it's like a scratch on a brand new car, it's annoying me a LOT.

unfortunately, that's just how they all are. has to do with the display type. both of the nexus' i've had were the same way, as was the display unit in my local verizon store.

You aren't seeing "banding" in the traditional screwed up screen sense, you're seeing the back of the display. I think it's just part of being SAMOLED and Pentile. I never noticed it until I started reading all the threads about people complaining over "banding" (and I don't think you're complaining LOL ).
Bump it up from the dimmest setting just a bit and most of it will go away. Our dimmest setting is REALLY good, at least compared to my old SGS. I also like how are screens don't have that SGS SAMOLED blue tint to them.

go to that call log screen again and press vol down + power. then look at the screen shot on the computer.
it looks the same
the background is ment to look like that

All 4 phones and 7 models that I've gotten to use from Samsung have this problem.
SAMOLED just isn't very good yet.

happy to hear my phone is not defective, but then again im very disappointed that this is a quality issue with the phone.
I read tons off aritcles discussing the difference between Super AMOLED and Super AMOLED plus (pentile and RGB) and this forum probably did the best job of explaining it
now is this also the reason why whites arent really white while having hte phone in auto brighntess? is the screen is dim, my "people" app is not white, actually far from it. but when the brightness is maxed out it looks magnificent

I was disappointed by the screen quality at first too, but the more I use the phone the less I notice it. I've even started to really like other aspects of the display that were lacking in other phones with a "clean" screen. Colors are much more vibrant for one, this is very visible when watching videos on the phone when I'm at the gym.

[Q] Yellowish tint near bottom of the screen

I just picked up a 2013 Nexus 7 this weekend as an upgrade for my 2012 model. Seems like a solid upgrade so far but I'm bothered by one item and it's the yellowish gradient toward the bottom one or two inches of the screen. I need to tilt the device maybe 15 degrees away from me to get a more consistent color. If I rotate the device 90 degrees counter-clockwise (camera now on the left), I can still see the yellowish darkening on light screens on the right. My 2012 model has consistent color throughout. I found a number of posts regarding people complaining of about a warmer color to the 2013 screen but haven't seen anything describing the gradient I see. It's rather annoying when reading webpages or ebooks with a light background.
Anyone else see this on their Nexus? Did it improve with time?
I tried to take a couple of photos but my camera doesn't seem to be doing a good job of picking up the colors.

Common issue
I returned mine (because of it) and got a new one which had exactly the same thing.
I also checked out a friend's N7 and had the same thing.
So I guess it is a normal thing. It is hardly noticeable and only on white background.
(Most panels have some kind of uniformity issues. I checked an iPad 3 and had some other issues...)

Thanks for the feedback. This is actually driving me nuts and I'm going to take it back to see if I can get one with at least less of the effect. Mine seems to be worse than the display model in the store I saw today. If they can't give me something that's equivalent in color consistency to my 2012 Nexus 7 then I'll return it and just stick with that.

If I were you I wouldn't bother.
In the store there are other ambient factors that may trick you in believing the store's sample is batter. But it will not.
3 samples I checked are exactly the same...

My device have yellow tint to. How to fix? "Screen adjuster" and other not helped for me.

I don't believe that this is correctable with software. I ended up getting a different tablet altogether and even this 10" one has the same issue. Guessing these panels are all coming from the same manufacturer....

Does the nougat update fix the youtube lip sync issue?

Also does nougat allow you to calibrate the color of the screen?

Yes it fixes the sync. No unfortunately no calibration of screen just the regular two modes. I also want color control as I want to make my screen a little cooler. We can just hope for a custom kernel in the future that allows this. ElementalX dev has stated he won't make anything for the P2.

If mine would had been just a tad warmer I would have thought about doing the same. But in "vibrance" mode it's good enough (barely). I can stand it as the eye gets a little used to it.
There are ways to make it a little cooler anyway. Check the app Screen Balance. It will mess with your blacks but not very much if you keep the opacity <50%. It's a tradeoff but it can help.

Actually that's what I've been using, it makes the black looks like dark blue...
The screen just isn't that good, not sure why so many people jump on the amoled bandwagon
LCD is more color accurate, no risk of burn in, the white looks so much better and the quality of LCD is always consistent unlike amoled which varies everytime.

I completely agree with you on every point. I'm an LCD person too for the same reasons.
Though I have to say I'm happy overall with this screen because of one reason, it's the most uniform screen I've ever had including all LCD phones I've had and they are a lot. My screen is pretty much perfect i never get this lucky certainly not with Amoled.

The sync issue is fixed and I don't have any problems with the screen. For many years everybody was loving the oversaturated amoled Samsung screens, but now there are opinions that some prefer lcd. Well it's a personal preference, lcd screens have bad black color and also drain more battery regardless what you're doing on your phone.
