[Q] NC LCD Whiteness/Brightness Differences?

Hi All,
Newb to XDA forums tough I have been following quite a few of the development threads for weeks now (OC Kernel, Phiredrop ROM, Tablet Tweaks, etc...). First I must say I'm super impressed at all the development being done for the Nook Color, us NC owners are definitely blessed to have an active XDA community full of brilliant developers!
But here's my first question about the Nook Color, has anyone noticed that some Nook units have a whiter/brighter screen than others?
Long story short is I've gone through about 5 NC units bc of various problems and have noticed that two of the five units I've been sent so far have noticeably whiter and brighter screens than the other three. This is with the brightness setting set at the same level on each Nook. It might be a color temperature or RGB setting difference between them, but I have no clue how or why they would be different since they were all factory fresh units. Does anyone know if Barnes at some point changed color settings (within kernel?) or started using different IPS LCD parts during manufacturing at some point? I did notice that the two I had with whiter/brighter looking screens had serial numbers that started with 20111, while the others had SNs that started with 2010 or 20110. Maybe they made some settings or parts changes during the newer production runs?
I know a lot of you might be thinking I'm not judging them under the same lighting or that the brightness settings are set to different levels, but I assure you that I am placing them all next to each other and always set them to the same brightness level for comparison. Admittedly, I am a bit particular about how the quality and appearance of my LCD screens, but even my girlfriend who is not a big tech person can easily tell the difference between the screen by looking at them from a few feet away. She instantly picks out the one that has whiter whites and appears "brighter" (again with brightness set at the same level).
Of course if you don't have two of these units next to each other for comparison it might be hard to see the difference relative to one another, but I can assure you the screen whiteness differences are there between some units. Wondering if there is any way for us to control these settings via kernel changes or some other changes (color temp, hue, RGB)? My problem is that I currently have a perfect unit that has the dimmer screen, and a brighter unit that has a dead pixel and am trying to decide which I should keep and which I should return. I actually prefer the colors and appearance of the one with the whiter screen but get distracted knowing there is a dead pixel. So it's a tradeoff. However, if i know I can change the colors of the screen and make the good unit look whiter/brighter down the line, I will definitely keep that one.
Any thoughts/advice would be much appreciated.
Thanks!

anyway u can post a high def video of this? would help on what your seeing. my nookn color is def a lot yellower than my other devices. but never saw a nook that's whiter than the other

I can try to take a video tonight, but not entirely sure if the color/brightness differences will be captured on the video but i'll give it a shot.
I tried not to use the term "yellow" in my initial post since whiteness level is relative, but that's basically how my gf described it - "That one looks yellower than that other."

yeah, i find whites on my nook very "yellowish" compared to my phone.
too bad there's no settings to change the color temperature on the nook.

Actually, that was one of my questions. Is there any way to change the color temperature of the Nook LCD screen or something along that line via the kernel? I have no clue about kernel parameters, but was hoping someone like Dalingrin, the resident kernel guru, might be able to answer this question? I think I've seen some ppl create apps to update color settings in the kernal for android phones.

I have an NC with serial number started 2004, which has very beautiful screen, but just three dead pixels. so I called B&N to have a replacement, and yesterday, the new one arrived (serial number 20112..). When I have both devices sitting next to each other, I can instantly tell the new one is VERY VERY yellowish (or say, the color is way too warm).
I have to call B&N to have another replacement, and the representative told me the yellowish is a known issue, though happen rarely. My personal experience can tell that even the newer devices may still have the yellowish problem.

There goes my theory about newer serial numbers. Have no clue why some units are yellowish and some a nice white then. But so far out of all the units i've got the ones that had whiter screens all seemed to either have dead pixels or some dirt or other particles stuck underneath the glass, and the ones with the yellowish screen seem to have no other screen defects. Probably luck of the draw, but I've got some pretty bad luck so far then. Love the NC, but I'm thinking the quality assurance is pretty shabby at this point.

Sorry if this is OT, but this is the part of your post that most caught my attention. What the hell are you doing to those poor Nooks? ;-)
But seriously--what the hell?

Lol... as mentioned, two had dead pixels one of them the pixel were dead center, one had dirt under the glass, another had a loose back and a yellowish screen. Now trying to decide which of the two I have left to keep. The one with one dead pixel on the right side but a white screen, and the other that has a yellowish screen but no other issues at all.

I hear u with the yellow tint. had this next to my bros Ipad 2. and the nook was embarrasingly yellow. and my apple fan boi bro said it looks like a macaroni n cheese screen.

Our first had a definite "yellow" tint to it. VERY hard to notice, but I seem to notice every imperfection. Exchanged it and the second looked better. A friend of mine bought one and it had the same yellowish tint. Doesn't bother him though. Says he doesn't see it.

Are you running the stock rom/kernel? I know on CM7 there's definitely a more yellowish tone to the screen than on Nookie Froyo or the stock rom.

Didn't realize there was such inconsistencies with the NCs regarding color temp until I read this thread. Without being able to compare screens I have no problems with mine as it seems pretty good to me, serial 2010xx dated Feb 2011.
I guess I was lucky that the one I bought had a good screen without a single dead pixel. That was the only thing I checked as it was the most important thing to me. Couldn't care less about any other cosmetic issues. Build quality was better than I expected for something of this price, but recently the left side of the bezel has started to creak annoyingly when I hold it.
Definitely can't compare to those tablets twice it's price. But AFAIC, it works very well and with the phenomenal dev support, a Nook running CM7/OC can't be beat.
If I were you, I'd return the one with dead pixel. Built into CM7 there is "Render effect". Besides the night modes, there are some basic calibaration profiles in there. Maybe one of them might make your screen a bit "whiter".
edit: I just checked and it seems all the N1 profiles made my screen seem warmer. I suppose a few more profiles can be implemented, perhaps you should start a petition to the devs?

(Read Story)

I'm onto my second Nexus 7 now due to screen lift. The last one I bought from Tesco and this one I bought from Carphone Warehouse. I did all the relevant tests for a defect when I opened it but a couple of hours later I realised that I have a really minor case of ghosting, I have to leave it on one screen for a while and it only ghosts the bottom third of the screen. I can live with that. Last night I also noticed a black idle pixel which is dead. That annoys be but its only visible if I look closely. I also have the tiniest bit of screen burn on the top left side but that's alright, to me. If I put pressure on the left side of the screen it has a sort of burn that is not unlike the one you get when touching a television. Also the colours are really washed put in comparison to the Galaxy S2. I know that the S2 is oversaturated but its not just a little bit. The green background in 'dead pixel test' is a pale lime, almost white in comparison the S2 is a deep lime green colour like the 'crazy Sour' skittles. I obviously have a few options:
I could keep it - gaming is fine and fun
I could get a replacement from CPW at the risk of the other one also having issues
I could refund and get one from Google Play
I could refund and buy a dishwasher (Dead serious)
What do you think? Anyone ordering from Google Play recently have any issues? I heard they're "clean". Thank you so much.

I got mine from the Google play store and it does have some very slight ghosting, but i kinda expected it for a device like this. I dont really notice it when watching movies or playing games.
As for your burn in issues, i think you should get a replacement as that shouldnt be normal

You poor thing.

I think I'd give it a little bit of time to see if it goes away on its own. New Screens are sometimes prone to minor issues like that. I would see if it still persists close to the end of your return window. Just my 3 cents on what I'd do.

Is my RMA nexus 4 really "BRAND NEW"

So I put in an RMA for my nexus 4 since my earpiece was not working, i got in on the first day of sale, and other then having to make calls through speakerphone, ive been extremely happy with the phone.
so i put in my RMA, and just received the unit 2 days ago. and i have some concerns.....
for starters, the screen on the replacement unit seems to have something wrong with it, cant quite figure out what it is, its not the common yellow spotting issue, its more of a washed out, lack of brightness issue. its not as bright as my original, and the whites seem dull and off-white, and the greys( particularly the settings menu) seem to have a yellow/greenish tint. I tried the color calibration apps (both the nexus 4 display app and the faux app) nothing seemed to work.i have taken pictures to show the differences.
another issue is with the back glass. If you see the pictures around the camera opening, my original has a noticeably bigger opening then my replacement, god knows why, but this ties in with the tittle of this thread and my concern, could this back glass have been broken and replaced by LG and passed off as a new in box unit?
the last piece of this puzzle is with the packaging itself, the box was new, had original black tape security tabs identical to my original nexus, also the screen protectors were in place as well, also identical to my original nexus. but what was definitely not present was the thin tiny strips of vinyl covering the chrome bezel, there was 4 in total on my original, this RMA unit had none, what gives?
so there is it, sorry for the long rant, just wanted to see what everyone thinks about this.
pics showing the difference in screen quality, original unit on right, replacement on left, also my original unit has the larger camera opening, let me know what you think.

Yellowing is normal with IPS Panels, it's the glue drying, give it a few days and it will be gone.
The camera lens has been discussed in other threads. It's apparently a hardware revision and makes no difference with the camera quality

I don't think my Nexus 4 had any plastic wrapping around the chrome finish. Anyone else?

There was none, the device was bare.

You seem to have gotten a rev 11. Give the RMA a week and then compare the screens. The yellow will be gone by then. As long as the yellow is uniform you should be good. Be grateful you didn't order an RMA this late and got an original rev 10. I think the 11s have better battery life and less light bleed. The rev 10 I received is awful... Came gritty and full of dust. Also had a nick in the glass underneath the factory screen cover, a black unfinished dot on the chrome, and a piece of debris under the glass. The yellow on my screen is only on the lower half of the screen. This is my 4th nexus. I have no. 5 on the way. Hope I get a good one the next time around.

How do you tell which revision it is?

well, now that you mention it, that was one of the things i did notice, was less light bleed, total darkness with black background, my original unit has 2 spots on the top with very small light bleed, the new RMA unit has a tiny hint of light bleed in the same spot.
so im suddenly feeling alot better about my replacement unit thanks to you guys, my biggest concern was the missing vinyl pieces over the chrome bezel, glad to hear its normal.
i still have 18 days to send out my original unit, ill keep using it daily with full brightness and compare after a week.
Also, where was the camera opening change discussed?

I would like to know this too.

just confirmed, you can check your "rev" model by booting into fastboot, (hold vol up and vol down + power)
so my original is a rev-10 manufactured in 10/20, my new RMA unit is a Rev-11 manufactured 12/10, i hope the screen improves

Mines a rev 10 and it's great, no issues, no light bleed, no yellow screen, none of that stuff.

The yellowing is not glue and it will no go away, my rma has a yellow tint and after weeks of use it is still there, my RMA also had the smaller camera hole aswell, waiting on my third nexus.

no vinyl on my bezel at all. Mine was not RMA.

Yeah, my N4 did not have any plastic on the bezel when it arrived BNIB. My RMA should come this week or the next (Bluetooth does not work on current device on Stock firmware and custom as well) and I will compare the two to see if there are any differences.

No vinyl on my bezel as well. (original phone)
RMA will be here soon, will update on that too

I received my RMA on November 29th. I have perfect Nexus except for some light bleed at the top. That's not a big deal especially since it's an IPS display. No yellowing, whites are perfect, no overheating, and I have a "faster" CPU.

They've probably increased the gap around the lens so if the back glass cracks it cannot crack quite as close due to a bigger gap?
I also wonder what impact colours have around a phone camera lens because the black is quite reflective but the grey part isn't.

This sucks to hear..... So the phone itself is not bad, the screen seems great and bright, but when I put it next to my original nexus its amazingly noticeable, and that's what kills me!!! Knowing that I do t have the best screen experience possible, ugghhhh
I called in the issue and might pursue another RMA, but I think I'm gonna wait a while, perhaps "rev-12" or whatever comes next will be better, but the screen is killing me right now!!!

Mine kind of yellow. But I don't care really. I change my phone every year or so. So it's not really big deal. The screen very crisp colors are very nice.

I regards to the yellow tint... Does LG out source their LCDs? Reason I ask is because the comparison shots just look like different screen temps. When I was buying iPhones, this was a common issue because apple used displays from both Samsung and LG. I had bought two phones on the same day for my wife and I, both the same model, and my phone had a very blue (cool temp) hue as compared to my wife's, which was much more yellow (warm temp). Just a thought.

[Q] Anyone else have parts of their screen with red tint?

Here's an image of my first Nexus 6 (top) and the RMA replacement (bottom): http://i.imgur.com/wNbgFo1.jpg
As you can see, my first N6 had a pink tint across the whole screen which is why I initiated the RMA. While the replacement is better, there's still a red tint to the right half (bottom half in portrait). Actually looking at both, the reddest tints are in the right half.
I also have some bands that are dimmer than the rest of the screen which is very noticabke when scrolling but not so much if looking at a static picture.
It seems these really are using Note 3 Samsung AMOLED panels because the same complaints were posted on another thread last year.
Both devices were manufactured 11/12 if that makes any difference.
I'm just wondering how common of an issue this is. I don't think I'll RMA again for awhile as I'm just taking up devices that should be going towards fulfilling orders and my replacement is serviceable. But considering the price, I really expected better and I don't think I can stomach the flaw.

You answered your question (the very end statement). I can't really see what you're trying to show in the picture as everyone see's colors differently and not all phone displays/pc monitors are color calibrated in the same ways. GL finding the right display for your tastes. They all have compromises albeit some less than others

You don't have to have a calibrated screen to tell that the top screen is darker than the bottom screen. It's also not hard to tell that the left is lit brighter than the right on both. Whether you see pink or not may be arbitrary but that's why I put it in the description.
My original question of if anyone else is having that issue is not answered just because I found a thread on a year old phone that may or may not be using the same panel Would prefer if other owners chimed in so I don't waste my time RMAing if it's unavoidable.
But thanks for the reply.

I have the same problem, the upper part of the screen has a pink Tint and it's bugging the hell out of me, but since i've had my friend bring it with him while coming back from USA, i'm obligated to swallow up whatever defects i find in it

My mistake. In your picture it looks like the right side of both screens is a little darker than the left.
That said, and you don't have to answer these I'm just thinking out loud here, what were your camera settings when you took the picture? What camera did you use? What screen brightness was each display set to? Could the ambient lighting in the room have affected the photo results? Could there have been inconsistencies in the results caused by the angle of the photograph taken? Those are a few of the variables that I can think of that could skew what we're all looking at.

I used a Sony NEX-5R Mirrorless DSLR. I probably didn't use the best settings (automatic with manual focus) but I was kind of in a rush to get the old one out to UPS to get the CC hold for the new one to drop off. I didn't use any special lighting, just natural day time lighting. I think the pics are pretty representative of how tinted they were though because the old one was very red heavy everywhere. I should have taken additional pictures of the home screen to compare. On the default background, the new one looks turquoisish but the old one was dark blue.
Brightness was at 50% for both and I believe I had adaptive brightness turned off. Either way it was light up much brighter than I keep it at day to day (I usually have it at 25% at most with adaptive brightness on). If I had to compare the pictures to the actual devices I'd say the camera didn't pick up enough of the red tint. So in person, it's much more red and much more obvious.
But honestly, I don't care that much about the tint as much as I do the uniformity. I can live with an all yellow tint or an all red tint if it was consistent across the whole screen. I'm sure a custom kernel will come out at some point with gamma calibration so I can adjust as I please. But the way it is, the top half of the display looks brighter than the bottom half. The easiest way to see this is by setting the keyboard to Material Dark and putting the phone in landscape. The left side of the kb will look greenish grey and the right looks darker purpleish grey.
I've not heard anything about this issue. Maybe one or 2 posts on here and reddit regarding banding. Everyone else says their screens are perfect. I was hoping people would share their pictures so I can tell if I got 2 bad screens or if they're all like that and most people just don't care.

Welcome to the world of amoled. .lol The note 4 has same issue.Replaced 3 times still have pink/purple hue..If u test this image out with brightness turned down a bit you'll see darker area's on display that's causing the issue.

I can see the light / dark difference in the screen with that image, but it doesn't bother me across such a dark background because it still looks grey all over (just to different degrees). I actually find that it's much worse with light backgrounds because it doesn't look all white or light grey. The darker parts are always pinkish. It also doesn't help that Lollipop is all about white screens everywhere either
Also found out that I don't qualify for the extended holiday return, so I have until Friday to return it for a refund. I guess I'll be calling for device #3 earlier than expected and crossing my fingers.

My note 4 looks similar to ur replacement device, the first 2 were really bad,half of bottom was really pink,2nd one the top half was really pink..This one I'm learning to deal with,it just blew my mind last night while laying down in dark messing with wallpapers and noticed all the uneven darkness on dark grey image,dark area's and faint vertical lines everywere.It appears it's from uneven distribution of glue.

I dislike the warm color on mines. Nothing is perfect, there's always something to disliked

Just wanted to toss in my 2 cents. I have had two Nexus 6 devices now, both with discoloration. Both are from ATT. The first device was darker to lighter, from left to right. Current device is darker on top, and lighter on the bottom. It is really frustrating because I love the size, and the screen is great in terms of resolution.
I am thinking about taking this one back as well and returning it. I have never had problems on my smaller devices. It bugs the crap out of me that I can tell the difference, mainly on lighter backgrounds. I don't think I can live with this phone for a year. Waiting on the M8 GPE to get lollipop might be a better solution for me.

Do you recall what the build date for both phones were? Not sure if it matters but couldn't hurt to collect that info.
I just called for RMA #2. Hoping it's at least not worse than the one I have now. I think I'm in agreement with you regarding just returning it and waiting until next year, but I already gave the Nexus 5 to my wife so I'd be downgrading the Nexus 4 she had before that...ouch.

Assuming the date under the sequence number on the box is manufacture date, this one looks like 11/17/14. I didn't think to check out the original device build date, but it shipped 11/18/14 from ATT online and I received it 11/20/14.
I have had my current one now for a day, Moto and ATT claim devices shipping currently shouldn't have screen issues, although my issue is different than the screen not turning on, or flickering.
I was so ready for a big phone, I am still within my 14 day return period, and I'm wondering if I should try this again to see if I can get a good one.

Hi All,
I'm coming in late but I just got my Nexus 6 from AT&T last night. I've been using an N5 since may and haven't had any issues. I noticed this morning when opening Hangouts, Chrome or any other page that displays white as the background that on the top it has a more greenish hue and towards the bottom right it has a purplish hue. I thought it was my eyes at first because it's subtle but when I'm paying 700.00 for a device it better have a perfect screen. So I played around with the adaptive brightness, rotated it etc. It didn't look any less green to purplish. The bottom right side of the phone in portrait (to the right or the charging port in portrait at any given appropriate angle) had a more purplish hue than the top left (opposing the camera). I'll probably be going back to at&t tonight .. which sucks because I JUST got it set up how I liked it. I hate rooting anymore which is why I buy GPE devices. I could have gone with any other device and rooted and may have to get back into that game if this is how crappy this display is going to be. Also I might add that the encryption does slow the device down a little bit compared to the N5.
P.S. Ignore my sig, I need to update that..

For mine (bought from tmo) the bottom is slightly darker than the top. I only noticed when looking hard for the "link" issue. Out of all the issues I could have had, I find this the least annoying of them.
Over all I'm happy.

I just got my Nexus 6 direct from Google (one of the lucky ones) and for the first time ever, a phone screen is really bugging me. There is a tint, darker from left to right. The most expensive Nexus I've ever bought (and I've bought them all) and the worst display. Very sad.
Here's some images, one with contrast as it was hard to photograph. Much more noticeable to the naked eye.
Does anyone NOT have this issue? If so I'd rather take the chance on replacing it.
Update: Returning it for a replacement. Google kindly gave me $10 credit for the troubles.

I received my replacement. The screen seems perfect. No gradient. There are definitely some defunct ones out there, beware. Mine is going back now. I hope you don't get it.

Look for it... there are no perfect phones hahaha.
But congrats if you don't get annoyed with your new phone :good:

Visible pixels

Just noticed that I can visibly see the LED pixels on the screen.. Anyone else have this happen after having the phone for a bit?

It's 493ppi so seeing 1 OLED pixel seems out there even for most people. I have 20/10 vision correct with contacts and I can't see them even if I try. Maybe if I had a dead pixel I could see it, but normally I can't see anything.

My display looks like Christmas tinsel

Can you take a picture of it with another phone? If it looks like that I would RMA it.

I couldn't get the other phone to focus on the pixels. I put in a request with AT&T for a replacement under warranty.. Just concerned with the build quality of the device since I've only owned it for a couple weeks and have this issue. Its a damn expensive device to have issues like this.

I didn't have that issue on my first Nexus 6 but I did have a camera issue. My second one is excellent no issues so far. I had my first one for 7 weeks before I had to RMA it.

I have perfect vision (my optometrist is jealous) and I can't resolve individual pixels on the display when held at "normal" distances.
After using the Nexus 6 though, I can resolve the pixels on my N7 LTE under certain conditions, after never having noticed it before. Drives me nuts.

That's how it is when I use Mt wife's S5 it's almost annoying because I can see them sometimes when I didn't used to. That started after having my G3 for the past 7 months

So just to be clear, when y'all are looking at the screen with a white background, you don't see red, blue, and green dots, correct?

Not corrected. I can see them also. It is mostly because of the uneven pentile pixel layout. Coming from an LG G3 which is stripe RGB you will definitely see a difference in quality. G3 is much more ordered and cleaner vs N6 a bit grainy with slight pink side. However, in my opinion it is an illusion because of a vertical vs diagonal layout. In both cases the blend is even.
My guess is that your new unit will not be any different.

My previous device was the G2 and in certain lights you can see the pixels with the screen off, especially outdoors. However, I don't see the pixel arrangement with the screen off on the N6; and I don't recall seeing the pixels prior to today.. Maybe it wasn't evident at first and maybe my eyes are now focused on the pixels, but I don't think you should be able to see RGB light reflections when viewing the phone display straight on. My HP laptop has the same affect when the screen has some wet spots; but the fact is, I can wipe dry those spots and the RGB reflections are gone. I don't have time to go to a brick and motor store to view the phones on display, and the new device should be in my hands mid-week.
Here's a thought - I installed the Skinomi Techskin a few days ago (probably a week now). Wondering if this screen protector is causing this?

So are you talking about seeing pixels when the screen is on or when the screen is off?
The die of the pixel arrangement will be visible under certain angle in just the right light when the screen is off.
Also, screen protectors can cause this to be amplified for sure. It all depends on the quality of that screen protector.

This characteristic is just one of those things you have to put up with when you're dealing with resolution cheating samsung crappy pentile amoled displays. I was hoping that the QHD would be enough to overcome the pentile, but that doesn't seem to be entirely the case for some.
At least (if tmo ever decides to actually ship it) it won't be as bad as my last cheating samsung amoled... a 4" 800x480.
I figured going into this, that the display would be pretty crappy. Too big, and amoled pentile... but after suffering with non-nexus devices for a few years (last one was a "nexus zero" -- ADP1...), I just don't feel like fighting with the thing, so fact of being a nexus > crappy display.
