When I worked for a mobile phone mag, we often ended up with more than one phone of the same model and it was common, in fact nearly always the case, for the screens to differ. Some would be a bit more yellow (more cream) and you noticed that most with greys.

Yet when you looked at them individually they looked fine.

I really think some people are taking the screen issue far too seriously, having heard the reports of bad screens in reviews and not just looking at the screen and realising it's pretty stunning.

I doubt you'd find any phone where the screens were identically calibrated on every model. I must try the iPhone 5s, as my parents each got one last week. I bet even they differ slightly.
[Xperia Z1 General] sephstyler:
Is there a way to find out definitively which Panel i have in my Z1?

Compared to my old Z, the viewing angles are better, and the colour reproduction is better.

Compared to my HTC one and HTC butterfly S, its not quite as "punchy" in contrast, but thats about it...
[Xperia Z1 General] tonylcc:
Sorry, may I ask you something on how can you take such awesome photo? how equipment you used to take this phone, actually I want to see such clear picture to define the panel used, Thank you
[Xperia Z1 General] logzz:
you prove nothing by setting both screens to black as it does not really show the problem, the problem is the colours lack vibrancy and are washed out with a yellow hue on top. And if you look at my post a few pages back you can see the black strips down the side of each phone when I have it in gallery that shows my z1 and I can only speak for mine has a lighter shade of black then my xz
[Xperia Z1 General] muslim187:
How can it be that the Displays are so distinguish. Cant understand that on some high end product like the Z1.:confused:
[Xperia Z1 General] pesho00:
When i read this thread i was worried what to expect from Z1, now when i have it from a week i am Happy person ;)

Z1 has the BEST Display i had (i had over 10 different android phones up to now among them all Nexuses below 4, Samsung SII, SIII, Many HTC's....) - viewing angles are very good - i even can see everything at angles ~170 - YES there change in colors but a lot less than in Z!

Yesterday it was sunny and i have some direct sunlight test - it is Perfectly visible in direct sunlight, which is the First! I even set it along my wife's SIII - No similarities whatsoever SIII is "blank"

I don't know, might be i am lucky, but display is really best (it says Panel name = renesas sharp 1080p). I wish such luck to all of You!
[Xperia Z1 General] nishant786:
Okay I'm not really sure how much this will help, but it worked for me. Yesterday while showing off the amazing pictures I took on my Z1, I transferred them via Nfc to my brothers Note 3. I was depressed however at how much better they looked on his phone.

But then I went into display settings and switched off 'adapt to lighting conditions' and the screen literally changed in front of my eyes. It was much punchier. Now it would have gotten better with the 'X reality' settings but that's not to my taste.

See if this helps anyone.

Also of 'note' (pun intended), our screens do appear to be far more 'accurate' and better in sunlight than the galaxies, which I think is an asset to a true camera phone.
[Xperia Z1 General] WouterNLD:
How'd you figure its panel name? Did you use an app and if so, what's the name? Thanks.
[Xperia Z1 General] krispijn_s:
It's simple if you have root and the terminal emulator. Infos and a how-to can be found in this topic.
[Xperia Z1 General] silencer51:
I would swap my Z for a Z1 right now if it weren't for this stupid panel lottery. I think it would be helpful if we made a database of product numbers and panel types, perhaps some batches carry the newer panels.
[Xperia Z1 General] Jiyeon90:
What panel lottery? So far I have only seen Sharp screens, whether it's bad, good or amazing depends on the person, personally I think my screen is just fine.

[Xperia Z1 General] keithkii:
My Z1 also same......the screen color is obviously in yellow !!!!!!!
[Xperia Z1 General] silencer51:
Apparently not all Sharp screens are created equal. Some screens have poor white balance and contrast.

I've had an Xperia pro with a yellow-tinted screen in the past and it was very noticeable (had it exchanged for another one which was fine). So I'm afraid to get a Z1 since I'll be buying it from a shop with an almost non-existent return policy (which has great prices though).
[Xperia Z1 General] Jiyeon90:
I know about the screens with yellow hue, it looks like they have been calibrated differently, anyways I'm pretty sure this can be fixed with an update

[Xperia Z1 General] jonmorris:
I really don't think screens with a different colour temperature are faulty. That's why some phones/firmwares have the ability to alter it.

And given just about every TV and a lot of other smartphones/tablets allow you to change colour profiles, there's never going to be a 'perfect' image because people have different opinions.

That's why you can change a TV from warm to cold, and buy lightbulbs that have different temperatures. What you like I might hate, and vice versa.

(And then there's the backlight brightness and contrast to throw into the mix, but let's ignore that for now)

I am not sure why there's no manual control on the current software, as it sounds like this would solve a lot of problems - both for customers and Sony itself, which now has loads of phones being returned as faulty when they clearly aren't.
[Xperia Z1 General] Dpk1:
+1. Looking at some of the pics posted in this thread, I think people here love blue / purple tinted screens than neutral or slightly off whites. Mine is renesas sharp & I've never seen colours as accurate as this on any other screen. Screen & camera on mine are stunning. Whites are warmer whites (neither yellow nor blue), blacks are deep, sunlight legibility is spectacular & viewing angles are not an issue (though narrower than amoleds & ips).

Like you said white balance setting (like XZ) could've solved issues for a lot of people here. I am pleased with whites on mine but certainly many are not, hence I don't understand why sony decided to not include such a useful feature on Z1 :confused:. Hopefully, they'll add it in future updates.
[Xperia Z1 General] silencer51:
It is true that most smartphones have a very cold white temp (~8000-9000K) while most content is made for sRGB (6500K) which does look yellowish to most people. Also some variance in white balance among panels is normal.

Having said that, my faulty Xperia pro was definitely warmer than my 6500K calibrated monitor (I'd say around 3500-4000K), and unfortunately there was no option to calibrate the display.

As for the Z1, some pics of yellow displays I've seen posted online definitely look faulty and I'm not sure one can perfectly compensate via software for such a heavy tint (I could be wrong, of course)
[Xperia Z1 General] jos_031:
Xperia Z1 is the phone which have best color temp accuracy and color accuracy... I have seen..people are not just used to it... i think few are defective...but most people cant bear the accuracy... just compare it with nec color accurate displays... I think amoled is way to future.. if they could extend the life of organic LED... and disintegration rate is uniform... .also provide true RGB pixel arrangement... also make higher nits of brightness.. The main complaint of AMOLED is fault of android.. as android do not support deeper color.. support 30/36/48 bit panel. so that over saturation can be avoided..
[Xperia Z1 General] julianjc23:
I have been using my Z1 for more than a week. My model no starts BH903 and I have got a yellow tint. The screen looks awesome under white light for eg at work and out and about. At home it does look bit yellowish, especially when I compare it to Nexus 4 and iPad retina display. Happy with the viewing angle and battery that most of that day. Thinking of keeping the phone. I noticed restarting the phone sometimes does make the screen better.
[Xperia Z1 General] Daelyn:
Could you guys please write out the first six of your serial number together with panel type / manufacturer? If I'm not mistaken it's possible to get panel info from /sys somewhere.

This way we can, maybe, get a better "picture" of the case. If it's batch dependent or random. There's a thread where mention if they notice any yellow tint together with serial. Could the tint be related to panel type perhaps?

I'm going to grab one of these phones in coming days and it would be nice to know what to look for.

Edit:

Found the thread with info on how to determine screen vendor etc:

this is exactly how beyond terrible the black level is on my phone

http://www.youtube.com/watch?v=Ai3M7ndr6kY

is this normal?

as i try to avoid showing anything black as it just depresses me

the colors on the other hand are amazing

the viewing angles are bad but nothing serious the picture gets whitish at an angle
[Xperia Z1 General] natkaen:
when i tilt the screen on white background, white turns yellow. is this suppose to be normal?? my screen is abit yellow aswell, so i use filter your screen app and white/grey looks much better now.

[Xperia Z1 General] venom_hvx:
hi!

Is there any way to find what screen type is without rooting the phone? The Z method do not work.

I took some photos of the viewing angles, but because im a new user i can´t post the link.
[Xperia Z1 General] 30Seconds:
My black is very black. It's almost as dark as the bezel which gives a really nice effect.
[Xperia Z1 General] jonmorris:
Yeah, I find that the blacks are quite amazing - possibly the closest to an OLED display you're going to get from a backlit screen.
[Xperia Z1 General] Untouchab1e:
So my local store just emailed me back after getting a response back from Sony regarding the display panels. Here is what they said:

*chuckles* what a load of crap..
[Xperia Z1 General] chesterr:
TFT sucks they need to find a better panel, it drains more battery too. think about an old laptop with tft panel.
[Xperia Z1 General] Daelyn:
Seriously?! I think you should read up on TFT's. It's the tech and variants thereof used in almost all flatscreens except plasmas.
[Xperia Z1 General] chesterr:
Yea Sony's TFT panel is too old man, just agree on it lol. hey I'm a huge fan yet you gotta accept the face that IPS displays are the best, yet it's another TFT panel too, well why can't Sony come up with something like that? it's simply easy.:confused:
[Xperia Z1 General] Mioggle:
Can anyone tell me how to reset to the previous build number?

I updated my CB512 Serial one and the screened turned really yellow.

I tried pressing the hard reset and it didn't do any reset.

I tried restore to factory setting but the build number is still the updated one.
[Xperia Z1 General] Jiyeon90:
Do you even know what you are talking about? TFT is used in every smartphone display, duh

Skickat från min C6903 med Tapatalk 4
[Xperia Z1 General] Morlock O:
Simple answer:

1. it is because they already have a very good display technology in Bravia (one of the best TV out there)

2. Sony want to stand out among the rest so they focus on Camera technology and waterproofing technology.

I can also throw the same question on other companies. Why can't other companies come up with the same 20mp camera?

See what I did there?

other companies didn't even come up with 13 mp camera till sony came out with the Xperia S 12mp camera when everyone was on 8mp.

btw IPS is a type of TFT and so is VA MVA AMVA...
[Xperia Z1 General] LNJ:
How in the world do you figure that 6500k may look yellowish to some people? Do the HID lights on most modern cars look yellowish compared to the regular halogen lights?

Defective is defective. 6500k doesn't look remotely yellow. It's a bright white. More chance of it looking a little blue if anything.
[Xperia Z1 General] silencer51:
Read my post again. Most people, having grown used to overly cold displays find 6500k too 'yellow'. Just enter any electronics store, go to the TV section and set a TV to Movie mode (which is closest to 6500k). Most people will complain that it looks bad
[Xperia Z1 General] Gitaroo:
yeah, probably BS, but at least they did admit that there reused old screens from the Z and do aware that people don't like it.
[Xperia Z1 General] LNJ:
You're confusing true 6500K and perceived 6500K. We all know that no 2 screens will look identical unless calibrated properly.

And if they are 6500K will still never look yellowish even compared to higher kelvin rating.

6500k is considered a cold white.
[Xperia Z1 General] guddu2011:
Please tell me if my Z1 has yellow hue/tint.

In background I have my LCD TV/Monitor
[Xperia Z1 General] silencer51:
But its obvious we are talking about perceived white color temp here. If you spend your life on front of a display set to 8000-9000K and a phone with similarly cool whites (check display tests, most smartphones have incredibly cold whites) then switching to a proper 6500k display will take some adjusting - initially it will appear yellow-ish.

Back to the Z1, I just checked a demo unit and its white looked cooler than my Z's. Also, the screen is much brighter than the Z's. Viewing angles are better but still mediocre.
[Xperia Z1 General] Sean473:
Looks ok to me...
[Xperia Z1 General] maxl96:
I´m going to buy a Z1 in a Store in Austria.

So are there really any differences between some displays or what? :eek:
[Xperia Z1 General] chesterr:
Well yea I know that they use TFT technology, but still IPS is an advanced than the TFT displays on what Sony uses on their phone, and top of everything Sony uses the software tweaks to brush up their display like x-reality and triluminos, so because of that I think that's why they have that poor battery life also,

I am a die hard fan of Sony, and I will be getting Sony phones for sure, and I own a Xperia Z and I love it. My opinion is that they are focusing on the camera and the build quality atm, but in future they will come up with a good display technology.
[Xperia Z1 General] hoezay:
I had the yellow screen Z1 ( waiting for my replacement still ) ,and looking at yours, it seems fine.
[Xperia Z1 General] Jiyeon90:
As I suspected you have no clue what you are talking about.. Did you even read what I wrote?

TFT is a technology used in LCD and even amoled screens to improve image quality.

So if you say TFT is bad then that means every screen is bad.. Makes no sense at all.

their Q1 flagship I afraid is Z1f, they iphone 5s competitor
[Xperia Z1 General] naga.nino:
When color accuracy is messed up, near black levels are also messed up. If near black levels are greenish and brownish, color accuracy is, obviously, messed up. If accurate colors are washed out colors as far as you are concerned, you should definitely go with terrible color representation screens like super amoled ones, or "accurate" LG G2 screen. Also, my Z1 does not have yellow hue, so I really don't know what are you talking about. I really like tons of videos on youtube showing famous "yellow hue" without yellow hue, like the one I quoted earlier in this thread.
[Xperia Z1 General] Dpk1:
I totally agree with you.

My point, exactly.

P.S - Some people might actually have defective screens, like abnormal tint at some part of screen (or whole screen), but by & large the majority shouldn't.
[Xperia Z1 General] gtrab:
I've waited a couple of weeks to write down my oppinion:

PROS:

The Z1's display is great

Excellent readability under sunlight

Excellent collour palete, very true-to-life colours

Bright and vibrant

CONS:

Colors wash away when viewed at hard angles, but this doesn't bother me since my eyes are in the front of my head :p

Overall GREAT display. I have zero complaints.

PS: The whole "yellow hue" thing is a ghost IMO, maybe due to user eyes used to colder screens, whites are truly white

PS2: This "display lottery" rumor is a myth.
[Xperia Z1 General] Why So Serious?:
They're also going to be pushing out a Full HD 5inch IPS screen with integrated touch: http://www.j-display.com/english/news/2013/20131008.html and a Full HD 5.2inch RGBW OLED display (same sub-pixel arrangement as WhiteMagic): http://www.j-display.com/english/news/2013/20130521.html. This is especially noteworthy because it is a not a pentile arrangement like the recent Galaxy AMOLED screens, but a true Full HD experience which should also offer much improved brightness due to the extra white sub-pixel.

It'll be interesting to see which screen offers up the best experience...

- The WhiteMagic display will have fantastic brightness, but from what I can make out it isn't IPS.

- The new integrated touch "Pixel-Eyes" display is IPS and doesn't require a touch panel layer so will have a number of benefits... even better viewing angles, clearer display and improved touch response, but the brightness doesn't look much improved (if at all) on the current Z1. This may not matter so much with fewer layers between display and eyes though as less luminance will be lost.

- The OLED (or WOLED) display in theory should have great viewing angles, contrast and brightness. It could well be the one Sony opts for if they don't mind moving away from LCDs.

The Pixel Eyes and WhiteMagic displays are in mass-production now, and are being exhibited between 23-25 October at FPD in Japan so hopefully we'll get an idea of what they can do. The OLED display will probably land nearer 2H 2014 if not later. Personally I'm looking forward to the Pixel Eyes display the most. Quite happy for screens to remain at 5 inches, especially if Sony isn't going to minimise the size of the phone elsewhere (bezels).
[Xperia Z1 General] babylonbwoy:
Z1 f can't be next 2014 flagship! It is already developed and released in Japan, I don't think that Sony will sell a flagship less than 5", at least not now that they have success with thses big handset. Z1 f is only a variation of the main flag.

I hope that the display will be the next "improvement", now that they included a better camera (even if some users find that it's not enough, xenon missing blah blah), lots of critics are about screen and the related battery consumption.

Viewing angle is just BS...

I'm using Lux Auto Brightness application to lower brightness even at minimum sony setting the screen is still to bright and eat too much battery.

About the bezelgate : if you put Z1 on dock you immediately understand why and that it is the minimum size

I hope not, Z1 name was already used by Sony before the Ericsson venture, it was CMD-Z1 exactly, I wonder why they didn't made reference to it in marketing, I'm not even sure they knew that it was already used as a Sony phone name!

[Xperia Z1 General] bodson66:
Comparing my JPD vs my display on the Z1 not sure which brand it is but the xperia z, has white with almost a blueish tint to them but look far superior to my Z1. I can honestly say that my xperia z's screen has more vivid colours and nicer over all. My wife's ZL has the sharp and is almost identical to my Z1. I can not see any difference. It seems the JPD is still the best and I'm not impressed with the yellow tint to my Z1. Everything else about the phone is great though, juat wish they would have stuck with one screen maker.

[Xperia Z1 General] Mazzstrikers:
Exactly. I'm not a Samsung fanboy here and I really don't like the oversaturated colours on AMOLEDS but after owning so many different phones from HTC, Apple and Samsung, which all have 180° viewing angles, Sony's effort is very disappointing.

The thing that irks me is that their panel suppliers are making the fantastic ones used in competitors phones as well. Many of Apple's and HTC's panels come from Sharp too for example and they are just perfect. Which leads us to feel Sony cheaped out. This shouldn't be the case when you are paying prices so close to that of the 5S.
[Xperia Z1 General] cihanleanne:
Sony has this habbit unfortunately
[Xperia Z1 General] Mazzstrikers:
Yeah I'm disappointed to say the least. I was this close to getting a Z1 because the camera, battery and design was just so tempting.

One look at the display of the Z1 in store, I immediately got the Note 3. And I'm coming from a HTC One, I hate the oversaturated colours on AMOLED. Yet compared to the real pathetic viewing angles I'd rather live with the less accurate colour reproduction.

I made up my mind because I previously owned an Xperia Arc and Xperia S. The Arc is about 4 years ago and back then I knew this was the Archilles heel of Sony. Even to this day they have not got this problem of viewing angles sorted out. I was so hopeful that the Triluminous would be a radical change but it wasn't.

The irony is that the panel on the Z Ultra looks so darn good. They don't even want to put in more effort on the Z1. No more Sony until they get this right.
[Xperia Z1 General] Geoffxx:
my mate bought a brand new 5S and I compared the white level of both screens - his had a distinct yellow tint compared to my Z1 - go figure
[Xperia Z1 General] ruchirtrehan:
Two thing shall be clear, if you find viewing angles par pathetic all I can say is you're just a being a lovable fanboy of 'viewing angles' and even if viewing angles are decent/good and your stating them as worse you're just not ready to accept that angles are good coz you have it in your mind after reading reviews that viewing angles suck, I've seen so many people just coz they read fake/fanboy reviews even if they do not have any issues there mind and eyes still feel there are those issues which are not.

[Xperia Z1 General] babylonbwoy:
Nobody knows, unless you'll have it in your hands no way to know which one in it I think!
[Xperia Z1 General] cruzzade:
Pure speculation, the same as the claim that Z1 uses a TN display. I have a hard time thinking that Sony would market a technology the screen doesn't even have (triluminous), since that obviously would be fraud. And we all know that Xperia Z:s screen is not arranged in a triluminous way. It's of course quite possible that all the screens aren't manufactured in the same facility, as is the fact that two panels usually aren't exactly the same. But using a totally different technology, opposed to the one being marketed? Highly unlikely.
