Display in direct sunlight conditions

Hi, i would to know the legibility of display in direct sunlight. Is it better of the Omnia display?! Or the same thing?

i would also like to know this as well. i believe touch HD has an ambient light sensor, but it is a different manufacture than that used in iphone. also, the HD's sensor is below two layers of plastic (the screen and the touch/pressure layer), whereas iphone's sensor is just below the glass. so those of you who already have the phone, please report back thanks

The HD's sensor is not underneath the screen/pressure layer. It is in the opening for the speaker. The screen is not transflective therefore the backlight is required to view the display.

okay. sooooooooo.... back to the OP's question : does the screen brightness changes when the ambient light changes? and it is good to view in direct sunlight? i couldn't extract the ansswer from your reply.

yes the screen brightness changes with ambient light. Display is comparable to the touch pro when viewing in daylight, but as the iphone is transflective, it will obviously not be as good.

Hi, I've had the Touch HD for 5 days now. The display sensitivity does change according to the ambient light, which I find very useful when going in and out of buildings. The display can be read fairly easy even on direct sunlight. I was reading an ebook without any problems midday with sun over my head. As far as Omnia, I can't judge since I haven't used one. But I can compare it to my old Tytn II which was unusable in direct sunlight. The display on Touch HD is really great.

OK...this is good.

The Touch HD display is not better than the Touch Diamond display in direct sunlight. Unfortunately it doesn't come close to the superb direct sunlight performance of the iPhone.
I also own the Sedna and although this device is perfectly usable in direct sunlight, even with the display brightness set to 0, the colors are dull and also much worse than on the iPhone under the same lighting conditions.
I can't hide the feeling that HTC just wants to earn easy money, look at the video performance of the Qualcomm chipset, it should have improved from the TyTN II outrage but nothing has happened yet.
HTC wants to build an iPhone killer? I'm pretty sure they can do it. Unfortunately they would need to charge much more for such a unit or at least lower their profit margin. Apparently they don't need to do that...yet.

actually it is not very good ... i cant see well...
any tweaks to make it peform better under sun??

yeah, i can hardly see anything on mine in sunlight, it would be ok to make a call, but to text or read a long text etc is verydifficult, didnt even trey watching a video, are there tweaks or anything for the screen?

disable auto backlight adjustment and crank up the backlight! battery peformance will suffer but its much easier to read. I think there are screen protectors out there than makes the screen more ligible in direct sunlight. try searching for it. dont take my word for it though

You can install Lumos and set it such that in sun conditions, it will respond with an increased backlight performance. At least Lumos will allow your phone to auto-adapt to the light conditions.
As for my personal experience, I have an ultraclear-type screen protector and the HD is pretty much unusable in direct sun light. I guess that with a less classy screen protector, the display would be readable outside but I haven't checked this out yet.

I tried disabling disabling auto adjust and cranking up brightness for sun.
It ATE my battery, left low level screen light on and this just is not a good thing.
I am outside a lot and looking for a solution, cannot believe the screen is so clear and good until you hit the sunlight. This is as I set on laptop and type in sun.

Display light leakage on top corners of my X1 Screen? anyone?

Hi,
When I dispay a black background color on my X1 for example the pannel screen while it is switching to a different pannel or standard pannel I see a bit of light leakage on the top 2 corners of the screen from each side. A bit white, if you understand what i mean.
Does anyone notice that?
Thanks for the info

Yep I notice it too. Probably a case of bad backlight LED placement.
This screen doesn't seem to have as good a contrast ratio (black levels) as the one on the Touch Pro.

it's rather massive. Its even visible on camera mode when you have wide-mode off.
I hate living with imperfection.
How bad is it on your device?
I have to say its not visible when other colors than black are displayed

I'm probably seeing the same thing as you are - two bright areas on the top/left edge of the display.
The light is "leaking" because the display contrast isn't high enough and the screen assembly is a bit thin.
It's something I can live with, but I do wish SE had sourced for a better display. HTC has raised the bar since Diamond and Raphael, and this one is pretty good for a Windows Mobile device, but there are tons of even better screens out there - think Japanese super-keitais.

humm.. I was trying to look for the light leakage but I can't really seem to see it.... perhaps you could post some photos of what it actually looks like?

yup, it's there

don't see any leakage on mine...

I tried one in the shop and the screen was tilting left a little bit. Also the flip was a bit loose even in closed. Any comfirmation?

I'm pretty sure all devices have the same leakage problem. Just put on a pure black screen and look for the white cones decending from the top corners.
It's because of the led's behind the screen I guess

honestly, there's very little (leakage, short of better term) if not none. If you have seen TouchPro, it leaks like crazy...

Leakage is pretty terrible, no doubt about it. Wonder if this fault is only on some handsets?

My TP don't have this at all. Virtually no leakage. Pretty much solid black even in pitch black environment. Contrast and viewing angles are excellent. One of the best if not the best screen I've seen to date. Seems like they're using 8 bit panel instead of 6 bit TN panel. The latter have terrible contrast and viewing angle as standard.

lucky if u only seen it on top corners, mine are on all corners!

i don't see any leakage... went into a pitch black room and pressed the panel button and i see no white light coming out of the corners...

then you must have a rare TP, all the TP owners in Singapore reported to have the same leakage. that's if we are talking about the same thing with regards to light leakage...

Hi,
2 days ago a friend of me and me bougt this moblie,
yesterday i gave it back to the store, cause i've seen the white
leakage on my display too, on the devise of my friend its ok.
today I'll get a new one. Hope its ok there....
Thought it was damage or so....

Maybe I'm missing the point here. Do you mind posting a screen shot of the issue so we can be on the same boat? Now you've got me curious.

I'll try and post a photo when I get home later, mine is mainly in the bottom left half of the screen and it's really noticeable and distracting when viewing something dark.

Hmmm, I've definitely noticed leakage on my xperia, in the bottom left hand corner when in landscape.
I had a Touch Pro for a few weeks before I got the xperia, and the screen on that was flawless. I might give vodafone a ring and see if I can get it replaced...

Don't forget to switch the display brightness to full to be able to observe the leakage. When I watch the Bond trailer I can definitely see the leakage on the top corners when there is a black background in the beginning. It's rather distrubing but I do believe that all devices have that in some sort of extent. I think you just have to get used to it and live with it.

n1 in a sunlight

This is a big concern of mine. I love the specs of the n1 but I've read that nothing can be seen on the screen in direct sunlight. I'd buy an HTC HD2 because I can even read books in sunlight with it but they stick with the win mobile and I like to have an android phone. So what do you say about n1 screen quality in comparison to the htc hd2 screen?

The only people who say this are people who don't know how to use the phone. Basically there is an automatic brightness option that changes the brightness based on how bright it is around the phone. Unfortunately, it seems like this feature always keeps the screen fairly dim, so I don't like it.
I have this feature disabled at all times and keep my phone at maximum brightness. It looks perfectly fine in sunlight.
People who say the screen doesn't work in sunlight don't know how to disable this feature (ie don't know how to use Android / change simple settings).

I've seen an app on an htc hd2 that changes the brightness automatically but one can adjust the brightness for specific surround conditions (i.e it looks like a graphical equalizer). I do not own the phone but I was told that this app works quite good. Is there something similar for the n1?

I can attest the screen pretty much sucks in sunligh at full brightness. The beaming sun in south florida is relentless.

Yeah, the N1 is hard to read in the bright sun and its not just pooping on stupid people that dont understand computerz or a simple setting that fixes it, it just gives glare in the sun.

Most phones/screens, regardless of their technology, are difficult to see in direct sunlight. But then, why are you trying to read the screen in direct sunlight? Just turn the other way, or shield it with your hand. Not that hard to figure out, really.
I use the automatic light sensor all the time. The only time is gets confused is is in a dim room, bright source (window, lamp) directly in front of the sensor. You have to realize what the sensor is seeing. Often times it's seeing light reflected off your face, hence the up/down/up/down of the screen brightness.
I honestly don't see either as issues with the phone, but the users rather.

really? i will be honest, i cannot see **** in direct sunlight unless i have the brightness all the way up... and that screen on full brightness is a battery hog...

I have no major probs with mine in direct sunlight, it's not that much different to the G1. I'm sure there are phones with better screens for direct sunlight but it's far from unusable.
The auto brightness feature works fine, you just have to wait a couple of seconds for it to adjust. Only people who don't know how to use the phone disable it and waste all their battery.

Really. I usually leave the screen set to auto, on the odd occasion I've had to turn it up to the brightest setting, but as the last poster said usually it'll catch up and turn the brightness up itself.

Or people who don't have any problem with the battery? With my use the battery lasts for 20+ hours, which is more than enough time for me to get to a charger again.
I always have the brightness at max and have had it that way for all the phones I've had (where you can set the brightness). If I'm gonna be more than a day without charging it I'll of course turn it down, but it's far from a neccesity for day to day use.
Just checked my phone and it's been off the charger for 16 hours and I still have 53% left on the battery.

Brightness in the direct Thai sunlight is fully adequate. The only problem I've had is that in direct sunlight, everything else is well lit, and so reflects off the screen.
Brightness: no problem
Reflection off the screen: annoying.

False. I know this phone well and disabled the auto brightness within 20 minutes of owning the phone. As much as I love my N1, and would not trade it for any phone, the amazing OMLED screen is one of the worst screens I've used as far as clarity in direct sunlight. This is not an N1 problem, but a problem with OLED screens in general. Assuming the new iPhone that should be released in June will have an OLED screen, it will have the same problem in direct sunlight.
You can buy anti-glare screen protectors that help this problem, but you do sacrifice some of the stunning brightness and clarity of the N1 screen in regular viewing conditions.
There is no way I would trade the N1 screen for the likes of the iPhone screen as the benefits of the OLED screen in non-direct sunlight viewing far outweighs the difficulty seeing the screen in direct sunlight. In fact, the N1 screen is probably its most impressive feature (aside from its blazing speed).

of cause this is the n1 problem and yours in the end! How are you suppose to take pictures with the n1 if you see nothing on the screen? How you suppose to dial a number if you see nothing on the screen? Saying this is not the phone to blame but the screen manufacturing process sounds stupid to me.

I have never in my life encountered an electronic device with a screen that was perfectly readable in direct sunlight, that is to say, as readable as indoors (not even my laptop plugged in the mains and set to full brightness). Reason: no screen technology can provide as much brightness as the sun. Solution: accept it, and cover the screen with one hand while you use the device with the other....

take pictures: look over the device and hit the shutter button..
input: open you jacket and form the number while providing shadow with it, or provide shadow with one hand while forming the number with the other. It's a fact that you need to accept, period.

Video sunlight test
Here is a video I found, it basically compares the N1's screen in sunlight to the Droid's screen at three different brightness levels. Enjoy.

note, since I'm new I can't post links... just remove the space

The screen is really nice in normal light but yeah it sucks in the sunlight LOL Probably depends where you live but in sunny South Florida it's a pain sometimes. Doesn't matter which direction you turn definitely have to shield it with your hand and it's still pretty hard to read. I'm looking into getting an anti glare screen protector for it to see how that helps. The display is absolutely beautiful but i'm starting to think maybe oled isn't the best technology for cell phone screens

Oled
The main difference between the screen technology in the N1 and most other phones is that on the N1, as I understand it, each pixel emits its own light (OLED = Organic Light Emitting Diode) as opposed to a 'liquid' film lighted from the back (LCD = Liquid Crystal Display). The only technology that I know of that will work well in direct sunlight is e-ink.
It is not likely that a pixel or a backlight could ever reasonably compete with direct sunlight, but on an LCD screen it is possible for the sunlight to reflect off the back layer or to hold the device is a certain angle to 'perhap's see the image better in sunlight then on the OLED type display.
However, having the N1 myself, I have found that I am able to shade the display in full Southern California Sunlight well enough to function with the device. The OLED display is much too gorgious to give up for LCD in my opinion.

Display problem/yellowish left side

Just got my new SGS2 3 days ago, really liking it but stumbled into a screen problem and would like to know if it's just me/it's normal/I need to change a setting to fix the problem.
Just like the title says, the left side (about 1/3) of my screen changes the colour of the image to a more yellowish tint. This seems to happen just when the brightness is quite low, and tends to disappear when close to 100%.
It is rather subtle, but can be seen where there's white text on a darker background (white characters become darker the closer they are to the left border), or when looking at an uniform colour.
I created this test page to make the problem more apparent: http://fiddle.jshell.net/qFxsC/1/show/
When visiting it on the S2 browser and setting browser brightness to around 20%, it becomes quite visible.
Anybody else with the same problem?
EDIT:
We still DO NOT have pictures of a phone WITHOUT the problem described above!
If you believe your SGS2 has a perfect screen, please post pics of the notification area taken in the dark at both 0-20% brightness and 100% brightness!
UPDATE
Various websites have started to talk about this problem, linking to this thread:
- http://mobile.engadget.com/2011/05/30/is-your-galaxy-s-iis-display-yellow-on-the-left/

- http://gsmarena.com/samsung_galaxy_...y_uneven_brightness_yellow_tint-news-2719.php
I have just sent an email to GSMarena asking if they could check the unit they reviewed to see if it has the same problem. Of all the phone reviews I have seen, theirs seems to be the most focused on image quality, I'm sure that if their unit doesn't have this problem, they would be able to take clear shots of a flawless screen.
EDIT:
GSMarena took screens of their unit using the above test link, and while so far I believe theirs is the best looking display that we have seen so far, it *STILL* has the problem.
I am going to link this thread to samsung UK next, in the hopes they will give an official answer acknowledging the problem.
EDIT:
latest firmwares seem to fix this problem or at least make it much less noticeable.

Take it straight back and swap it. Seems to be a growing amount of people on here, including myself, with various dodgy screen issues.

The screen doesn't look perfect if you look at a uniform color on the whole screen + low brightness, but... well I don't tend to use it much for that. Could be a limitation in OLED production-technology getting all the pixels to have exactly the same brightness/color etc.
edit:
To answer directly to the question here, no I don't have a yellowish left side. It's just not completely uniform across the whole screen.

I've got this same thing. I first noticed it when using Estrongs file explorer. I always have my screen turned down to 0% to save battery, but didn't notice this anywhere else yet (at least I didn't think about it).
Your posted image does show it clear.
What to do? Could you others comment whether you've seen this? Go to the OP's posted link and set your brightness down to 0%.

I tried to mess around with settings such as auto adjust screen power etc, but the only thing that seems to fix it is crank up the brightness.
We obviously can't keep it anywhere close to 100% tho, this phone sucks battery down quickly already at 0%!
Another thing you can do to check if you have this screen problem is call *#*#0*#*#*
This will make the phone go in the diagnostic program, and if you try the white diagnostic, you can somewhat see the problem, although not quite as clearly as in the test web page I posted above.
I'm considering to return the phone, as it doesn't seem to be getting better, despite having read that some screen problems might go away after a few days.

Mine is exactly the same. It's noticeable at the lowest brightness setting, however if I increase the brightness even slightly it pretty much disappears for general use. It's still there but not really enough to bother me.
On the OP's link I changed the brightness through several settings and at certain brightness levels the whole screen gets a yellow tint. Not necessarily related to the left side of the screen having a yellow tint, apart from I guess a lack of brightness of the blue subpixels relative to the red and green.
I'm not sure if I'm imagining it but I think it has improved slightly on mine over the past week. However if it gets any worse I think a warranty claim will be in order.

Hhrrmm, I'm in a catch-22 here. There's generally a grace period for any manufacturing errors like this where you can quickly get a replacement just by returning it to the vendor. Problem is, my vendor won't be getting any new units in for another two weeks.

I don't see it clearly on the link he posted.
But i do see it in the notification screen. The grey area is slightly darker/yellow tint on the left site. Even when i put it on maximum brightness you could see it. Especially when you first concentrate your eyes on the right side for 5 seconds and than on the left side.
I do seem to notice it on the notification grey slider where your finger is on when you pull it down, on the left side the grey is a little bit "darker" than on the right side of mt finger.
I tend to think I can also see it on the keyboard, whereas the Q has different grey than P on the opposite of the screen...
Anybody could check this out on their phone??
Thanks in advance!

As time goes by, it feels like my problem is getting worse, although it may only be due to me being aware of it.
Also began noticing it in the pull-down message field. Now I see it against white backgrounds as well, almost like a faint green-grey shadow.
I've contacted my vendor and requested an RMA and replacement. They're sending me a shipping slip to send it to them "for control" then they'll contact me on my options from there. Can only hope they see it as clearly as I do and that they send me a new phone as a replacement rather than repair/refurb crap.
Think this is the last time I buy electronics online. I saved 20% off retail on this one, but having the option to do a walk-in replacement at a brick-n-mortar store would have been worth the higher price. <sigh>

I've got the same thing aswell, a slightly yellow/brown-tinted shade towards the left side of the display. Also visible for example in the market menues, the white areas seem to be very slightly darker towards the left side.
Not sure I am bothered about it enough to return it, doesn't bother me unless I specifically look for it. Also it really is very slight.

If everybody has it, no problem for me.
But if the majority does not have it, I would like to have one without it. Do you think Samsung knows abouth it?
When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?

Here is a photo I took of my screen with a grey background (see below - click on it to enlarge).
For me, its visibility seems to vary depending on the ambient light, but I'm definitely seeing more effects of it now.
Really hope I'm able to get a good replacement. Am reading quite a bit about this, banding, lines and dead/lit pixels.

so do you think it's a hardware issue, or maybe it will be gone??

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

My Samsung focus and Cowon s9 (which I don't even think has a samsung oled screen) have that as well on the lowest brightness, I think its inherent to the tech.

Ah ok thank you!
On a grey pick with full birghtness I can see them too.
On the post 2 post above yours(quist his post) you can see the lines, but now they are not white, but darker, can you confirm you see them and this is what you mean?
Do you also have the yellowish tint on the left side?

For both the SGS and SGS2, the dark lines are there for my devices aswell. They can seem a bit "grainy", and don't seem like perfectly defined lines, though they generally are always straight horizontal or vertical lines. I also have the Xperia Arc at hand, and if you look at a grey-ish image on either the SGS/SGS2, or the Xperia Arc (LCD), the Arc generally has a very smooth grey image, while the SGS/SGS2 has almost like a fine overlay of subtle lines or grids, generally darker in color than the image displayed, though not clearly defined and not completely symmetrical across the display.
Doesn't seem symmetrical enough to be a grid fo the digitizer layer or smtn like that, but definitely a pattern in the display itself. I still pick an AMOLED screen anytime of the day, the Arc display, while more uniform and "blemish"-free in this regard, still has that LCD backlight bleed-through which for me makes the display alot more tiring for the eyes.
Also my SGS2 has a very subtle tint towards yellow when viewing some of the grey test-images some people have posted. Never noticed it on my SGS1, so either I didn't look well enough, or it might be either hardware-related (something causing the pixels on the left side to perhaps not get the same amount of control voltage/whatever for the pixels, thus causing less blue/more yellowish color), or software. Either way, it is way too subtle for me to care at all, maybe this is even according to spec for the SAMOLED+ and some use will even the pixels out, not sure if anyone has some inside knowledge about the SAMOLED screens.

I am definitely seeing this problem getting worse, now it is getting rather obvious as long as phone is lit by artificial light or in the dark, while sunlight seems to make it really hard to spot, even if not direct.
I've been given advice from samsung call center to bring to phone to the closest assistance point, which I'm going to do tomorrow - hope to be able to report back that it is a known problem and they will change my unit.

I hate to make an iPhone reference here, since I'm *not* a fanboy, but Engadget reported when the IP4 was released that yellow spots and banding were due to glues that had not completely dissolved/disappeared and were part of the bonding process of the screen:
http://www.engadget.com/2010/06/24/iphone-4s-yellow-spot-issue-goes-away-with-a-bit-of-time/
Now - the picture above showing a completely yellow left-side display - that looks 100% abnormal and I'd RUN back to the store to swap it out. I don't think that's glue related.
Download an app from the Market called "Dead Pixel Test" and run it with the white setting to see what it looks like. Is it still yellow?

Have this same issue. Noticed it right away unfortunately. It will always bother me if I deal with it.

Yellow tint/band/gradient/screen/tinge - an Investigation

Introduction
If you own a OnePlus One and have kept up with news covering it, you should already be aware of the infamous "yellow tint/band/gradient/screen/tinge" (how many terms have been coined for this phenomenon?). If not, basically, it's an issue that has evidently plagued some* OnePlus Ones.
*I find that people can be generally divided into four camps:
All OnePlus Ones are perfect, the yellow tint doesn't exist
All OnePlus Ones are affected, none are perfect
Some^ OnePlus Ones are affected to different extents, but most are unaffected
Most^ OnePlus Ones are affected to different extents, but some are unaffected
^The proportion of affected vs. unaffected Ones is very unclear. Both of these cases are based on the fact that there are people who own OnePlus Ones that are completely fine, and the portion of affected users are the vocal minority.
I'm in the third camp. Mine has shown the tiniest bit of tint since day one (bottom 1/10th of the screen, more visible when looking down from above), remained unchanged after a month of owning it, and to this day remains unchanged as of the day before yesterday (17th December 2014).

SPOILER: Day Before Yesterday
Pictured: @Aaahh's pretty neat software fix, turned off
I need to learn how to work the manual settings on my camera.
When displaying a prominently white screen/image/webpage, there is a visible yellow "tint" (let's just call it a tint for now) at the bottom of the screen that's "yellow-er" than the rest of the screen, right above where the capacitive buttons are. It is also the edge where the backlight LEDs are situated. Now, its severity depends from case to case, and often it doesn't really affect functionality, but it's there, when it shouldn't be.
OnePlus has kinda addressed this in two threads, but the conclusion was a bit ambiguous. The first thread thread addresses an "overall yellowish hue", and details how OnePlus sources panels from JDI, different factories have different batches, different screen temperatures, other flagship phones also suffer from this etc....and the second thread thread lines up the One with other phones and is seemingly normal.
As far as I know, "officially" speaking, this issue doesn't exist. People have RMA'ed their yellow tinted One (success? failure?), others who have purchased multiple Ones have the tint on all of them (at different extents, never subsided), and some other stuff. I couldn't keep track of it all.
So, knowing me, I downloaded the RAW files from the second aforementioned thread and checked the EXIF data. I'm sure their one wasn't affected, so it wasn't to determine whether the image was doctored. I just wanted to know all of the settings they used to take those two pictures, so I could replicate those shots. It's a good opportunity to try out my Canon 450D!
Note that the Canon 6D is a full frame camera, and the Canon 450D is a crop frame, so there's a crop factor difference of 1.6x. Full frames also capture more light than crop frames, among other differences like how the 450D is only 12.2 MP and doesn't have multi-segment metering...it was free though, so I can't complain :silly:
Picture 1: f/4, 1/125 s, ISO 100, 24-105 @ 47 mm, no flash, using Manual mode and multi-segment metering (+ a whole bunch of other stuff)
Picture 2: f/4, 1/25 s, ISO 320, 24-105 @ 50 mm, no flash, using aperture-priority AE and multi-segment metering
My attempt at replicating those pictures (to emulate the wider angle of a full frame, I used a 32 mm focal length instead of ~50 mm, which also changed the aperture from f/4 to f/4.5):
Left is unaltered original, right is messing around with levels
Picture 1: f/4.5, 1/125 s, ISO 100, 18-55 @ 32 mm, no flash, using manual mode and center-weighted average metering
Picture 2: f/4.5, 1/20 s, ISO 400, 18-55 @ 32 mm, no flash, using aperture-priority AE and center-weighted average metering
I'll see if I can upload my RAWs too.
Conclusion? I'm a noob at Photoshop/photography. But I can see why people alter the picture and take them at extreme angles; it's too hard to capture on camera. You see it with the naked eye, but it's really hard to capture what you see using a camera.
From the second thread:
Another thing to consider when seeing photos of the yellow band problem is that a lot of the photos were taken at extreme angles with Contrast and Levels changed for more visibility. We have been able to replicate some of the pictures posted here by playing with the Levels settings in Photoshop and the angle at which the picture was taken. We have attached the raw files and settings used to manipulate them in Photoshop below so you can download them and reproduce these images.
Some people have complained that their screen’s yellow hue is due to a “bad” batch. This is not true. JDI and OnePlus extensively test the quality of the screens, and while the factory hue of the screen may vary slightly by batch, we can recreate the level of “yellowness” through software changes.

Interactive part! To those who have a yellow tint that's more visible than mine, take a picture of it and post it below.

Different Circumstances?
Yes, I am aware that the screen temperature variation and unevenly diffused backlight/yellow band issue plagues not only the OnePlus One. This will be covered in the posts after this one.
In OnePlus' first explanation thread, some points were made; OnePlus deliberately chooses warmer displays for aesthetics, different batches have varying color temperatures, the latest CM11S update (as of 21 June 2014) is calibrated to be warmer to avoid fatigue, and we are reassured that this can be rectified through software.
I think not all Ones have a distinctively warmer display (I must've missed that warmer displays window), because my One's display looked pretty cool on CM11S 38R, and still looks pretty cool on PA 4.6 Beta 6 at stock settings (PA doesn't have any options to change the tone of the screen) when compared with the iPhone 6+. Say what you will about Apple, but the iPhone 6 Plus makes a great reference display device, because it's factory calibrated to full sRGB standards (quoting an Apple Store Genius (lol) and Apple's specs page).
Here's the iPhone 6 vs. the OPO on LiquidSmooth Lollipop:
Since PA is not CM11S, it doesn’t have a default warm screen temperature bias. I have been told that PA uses a "stock" color profile. Whether this is stock CM11S or stock AOSP I'm not sure. I will flash 44S (edit: probably not) on my One whenever I can. I wish I hadn’t encrypted it. In order to remove the encryption, the whole internal storage (all my stuff and the system) has to be wiped too, and I'm having difficulty backing up the contents. (encryption works on PA 4.6 for the OPO btw, but only use it if you really need it; TWRP doesn't get themed if you encrypt the phone)
After occasionally looking into it on-and-off and not really yielding any definitive results, it can be deduced that there are a few main possibilities that may contribute to this yellow tint:
The backlight LEDs were placed too close to the visible display area of the LCD, so the light didn't have enough room to fully diffuse before becoming visible, resulting in the yellow tint ("the "all ones are affected" camp)
Due to high demand and low supply, the factory at which the screens were produced were forced to ramp up production, rushing the LOCA curing process, resulting in some phones having "undercooked" displays that have a yellow tint localized at the bottom portion (the "some Ones are affected" camp)
Something could be up with the actual backlight diffuser in the LCD
A combination of 1 and 2, because the tint is coincidentally localized where the backlight LEDs are
Heresy
I will try and investigate the validity of possibilities 1, 2, and 3 (3 mightn't be by me, because I don't have access to an OPO LCD that can be dismantled). I can't do anything about number 5.

Possibility 1: Backlight Placement
This was explained by a OnePlus team member:
1. Our fans have also brought up a yellow band the bottom of the screen fearing it may be a quality issue. It is not. Since brightness influences color temperature, the yellow tint at the bottom is due to the design of the phone. There are 14 backlights under the screen, which were not meant to be uniformly distributed along the screen but to be all at the bottom. Since we needed to make the screen shorter, the lights were put very closely to the edge. If we didn’t, we’d have a leakage of light.
Click to expand...

We are assuming this is a design characteristic (the "all Ones are affected" camp). I thought the bolded part sounded weird, because if the LEDs were placed further from the edge, wouldn't those 14 visible spots be hidden from view?
Also, after some quick Googling, apparently:
Brightness is a human perception, and luminance is an objective measurement
Brightness ≠ luminance
Color temperature affects brightness, not the other way round
That powerpoint was for entertainment lighting systems though, and it didn't specify whether the brightness and color temperature thing applied to halogens or LEDs.
The HTC One X/XL has a very similar display backlight configuration to that of the OnePlus One. The backlight array starts from the bottom edge, and it also has three backlit capacitive buttons.
The difference is the HTC One X/L's backlight diffuser extends over the capacitive buttons (requiring extension things to provide button backlight), and the OnePlus One's extends over it not as much (those white bits allow light to shine through the capacitive buttons, see two pictures ago).
Also, the back of the LCD is stuck on the chassis, making removal without damaging the LCD very difficult (more difficult than the OnePlus One). This one broke when it was removed from the frame
For this investigation, I'm going to measure the lengths of the screen bezel on the side where the backlight LEDs are (from where the display area ends to the edge of the glass), and from where the backlight diffuser assembly ends to the edge of the glass. Subtracting the second measurement from the first measurement will give us the distance that the backlight has before its light can be seen through the LCD.
Note: the accuracy of the measurements below aren't guaranteed.
OnePlus One
12.94 - 6.63 = 6.31 mm from end of backlight to visible display area
Sony Xperia Z
15.44 - 9.02 = 6.42 mm from end of backlight to visible display area
LG Nexus 5
14.96 - 9.56 = 5.4 mm from end of backlight to visible display area
Motorola Moto G (1st gen)
18.23 - 8.77 = 9.46 mm from end of backlight to visible display area
HTC One M4 Mini
10.81 - 2.83 = 7.98 mm from end of backlight to visible display area
iPhone 5
15.68 - 11.01 = 4.67 mm from end of backlight to visible display area
Apple iPhone 4S
19.71 - 14.12 = 5.59 mm from end of backlight to visible display area
LG G2
10.80 - 5.58 = 5.22 mm from end of backlight to visible display area
I don't think the measurements were very accurate, but from what we've got, the placement of the backlight LEDs shouldn't alter the color temperature of the display. The OnePlus One's placement is on-par with other phones' placement, so those spots may be more of a diffuser problem.

Possibility 2: Under-cured LOCA (Liquid Optical Clear Adhesive)
This possibility was speculated by users, and was not addressed by OnePlus. It has been said that exposing the OnePlus One's display to UV light or sunlight (apparently, 5-10 minutes in UV, 1-2 hours in sun) completes the curing process, thereby eliminating the tint. (will find sources when I have the time, it has also been said that this doesn't fix the tint/band)
Edit: might as well try the sunlight fix. I'd actually have to buy the UV lamps, and wait for them to post. Since my tint is barely noticeable, it's worth a shot. Bottoms up!
Looks like it did make a little difference! (or it might just be my mind playing tricks on me + wishful thinking)
We are assuming this is manufacturing process related ("some Ones are affected" camp). This would imply it is a QC issue, which it is not, according to OnePlus.
Samsung?
It has been noted that some Samsungs may suffer from unevenly cured LOCA. I have yet to see this for myself, but that's not to say it doesn't exist.
By design, Samsung's Super AMOLED panels have no discrete backlight; each individual pixel emits its own light. That's why dark/black images save power, and bright/white images consume more. Due to the nature of OLEDs, blue subpixels age faster than red and green, so the PenTile subpixel configuration aims to compensate for this by having twice as many (but smaller) blue subpixels than the rest. PenTile displays may exhibit a slightlu cool/blue tint as a result. An aged AMOLED display may exhibit a yellowish tint, due to the deficiency of blue.
Every generation has introduced upgrades and improvements to continually improve AMOLED tech. The Galaxy S5 and Note 4's displays finally outshine LCDs of the same class in terms of color accuracy/gamut, contrast, power efficiency, and uniformity of luminance. Sharpness has become increasingly irrelevant, thanks to the 500+ ppi of the Note 4. Any claims that LCD is objectively superior to the current generation of Samsung AMOLEDs is purely subjective. The only advantage that LCD has is its increased durability and lower price. They are less likely to fracture/crack and render the whole display useless.
I will get a phone that does not have a laminated display, and intentionally leave part of the LOCA uncured/under-cured in an attempt to replicate the tint where the backlight LEDs are.
How would this happen at the factory? I'd like to think the curing process involves a conveyor belt pizza-oven like device that "bakes" the display under UV light, but who knows!
We could ask Apple, since their iPhone 4 suffered from a similar problem
Update!: I think I should wear sunglasses next time.
I "only" put it in the lamp for 2 minutes, because that's how long the built-in timer is, and apparently some 20W UV lamps can fully cure a particular LOCA in a mere 6 seconds. I didn't want to risk damage to the LCD, so you could say I "chickened out"...
You can come to your own conclusions about what this means
In all seriousness, my One's probably not the best "poster child" for this, because I've actually heated the screen enough to separate the factory bond with the chassis, and exposed it to sunlight uninterrupted. We'll probably get more visible results by doing the curing process from scratch.
Pictured below is the phone in question; an iPhone 5S knockoff. Most of the better Chinese no-brand/knockoff phones have an OGS display (One Glass Solution), which is already laminated. It is like the OnePlus One's ToL (Touch on Lens), but not. I've posted on XDA before about it!
LOCA time!
As it turns out, the LCD is stuck to the front glass with adhesive tape all around the border. I didn't remove all of it, which resulted in some of the air bubbles to have nowhere to go
Get the display all clean, and apply the glue in an elongated "X" fashion:
I didn't have one of these:
So I used the phone's chassis. Bad idea. The glue leaked all over the place. The whole idea of the alignment frame thing above is to allow air bubbles and excess glue to escape, while also maintaining a uniform thickness between the glass and the LCD.
Lookin' good! This was the best I could make it. An autoclave would've came in handy.
Into the manicure UV lamp for 2 minutes. That should be inadequate enough!
The glue had already solidified enough such that air bubbles could no longer move around freely. The bubble in the top right corner became bigger, but other than that, everything went better than expected!
...or so I thought. LOCA had leaked underneath the LCD and into the backlight, because I used the chassis as the alignment frame, but it did not allow glue to escape.
The glue did not become yellow. It wasn't yellow when it was in liquid form, and I don't have much idea how long you're supposed to cure it for. Maybe it yellows further down the road?
Well, at least the properly laminated areas look great, and glare has been reduced. In hindsight, I should have used a display that could be replaced if I messed up this process.
¯\_(ツ)_/¯
This process is not going well with the Galaxy S3 display
If only I had gotten that $600 machine that make this process a whole lot easier (the frame laminator bit), or the lot for $4,250...

Conclusion?
We cannot come to a definitive conclusion at this point. The backlight placement doesn't seem to result in the yellowing, and neither does under-cured LOCA, since it yellows in a different fashion. Something's probably up with the design of the display itself, and it might have something to do with the color shift you see when viewing it from a different angle.
Either that, or like the touchscreen issues, there might be multiple causes of the yellowing.

Omg man, you deserve the crown of the unofficial Oneplus hardware development.
I'm so lucky to not suffer this problem (but i'm going crazy by the unresponsiveness of my touchscreen).

/p/ says your problem is that your using cannon I' just teasing man, this is an awesome post and we appreciate your efforts.

The complete yellower screen thing is really a color profile(ak has the old one, see the difference)
The tint 92% in the UK

The display may have been deliberately designed that way, but changing the colors counteracts anything out of ordinary.
In fact, I like it better than the Samsung and HTC, there screens look colorless or flat. I like my screen, it has depth

The S4 Active had a terrible display. It is not representative of Samsung's better displays.
I wouldn't say HTCs are dark. In fact, the HTC One M8 has a brighter than average display. Some OEM screen assemblies can be complete crap though.

It's just more accurate/has a wider color gamut that what you're used to on other phones.
Take a look at some of DisplayMate's Samsung display shoot-outs. The Galaxy S5 and Note 4 have some of the most accurate mobile displays on the market (not directly comparable with LCD tech).
