[Xperia Z General] Slim Shady:
yup from sony rep on td forums

Now coming to the screen of the Xperia Z. The first batch of Xperia Z used panel lottery system like Samsung TVs. 80% have Sharp panels, while the rest have JDC 1 and JDC 2 panel. ALL demo units have the worst quality - JDC 2 panel. So what you see in demo units is not what you'd probably get.

Let me summarize the three screens quick

1. Sharp - 1000:1 + Contrast Ratio, on par with the best screens on the market.

2. JDC 2 - 700:1 Contrast Ratio, This is what GSMArena got. It's the middle quality panel with worse blacks than Xperia S

3. JDC 1 - 450:1 Contrast Ratio. This is the worst panel of all and is found in ALL demo units and some retail units in Europe. I really have no words about this panel. It's a joke. You are 100% likely to see this panel in Demo Z at Croma and other outlets. EXtremely weak blacks and washed out colors with poorer viewing angles than even S/SL

Most of Asia has got the Sharp panel which is as good as Butterfly/One/One X/Xperia TX/Lumia 920 screens. There is very little chance you will NOT get this panel but to be sure

Buy a Z manufactured AFTER February 2013. Only the early batch uses panel lottery. February onwards 100% Sharp panels only are used. You can checkout the ZL screen to get an idea about the Sharp panel on Z. All ZL have Sharp panels.

So best thing to do is buy a fresh stock Z next month, you'll get the high quality Sharp panel.

Also screen calibration app will be provided by Sony in 4.2.2 update coming in 2 weeks.

In short, Z screen is NOT inferior to Butterfly/One or any other phone but the fact that ALL demo/review units feature poor quality JDC panels. Most Retail Z in India have Sharp panels which has good black levels and high contrast along with accurate colors. I've seen one myself so I do know what I'm talking about.

[Xperia Z General] make87:
Any source for this claming ?
[Xperia Z General] TechGuru_x10:
Everything is B.S., if no online proof available. I have JDC, I have compared the 1080p movies on my full HD tv and the colors and contrast are same. Perfect black.
[Xperia Z General] Slim Shady:
K then has anyone compared The with Jdc panel and sharp panel hands on side by side any distinction???
[Xperia Z General] dartagnan04:
Wow! So much information... But I'd like a real source.
[Xperia Z General] Slim Shady:
Well buddy this was all I was able to get and the guy's a Sony rep so should be authentic
[Xperia Z General] dibdin:
Sometimes even a Sony rep can get things wrong.
[Xperia Z General] lilstevie:
Seems legit. I can imagine marketting sitting around and saying "oh yeah, make sure to get manafacturing to grab all the poorest quality devices together for journalists, that will really make these devices fly off the shelves".
[Xperia Z General] moraal:
Slim Shady's explanation makes sense, but Sony's decision here seems ridiculous indeed. Doesn't make the story untrue.
[Xperia Z General] TechGuru_x10:
Let me prove the Sony Rep wrong. Mine is JDC and Mine is of Feb.
[Xperia Z General] jerdog:
Let's do this... Can you prove anything? No. Can you prove that person who claims to be a Sony rep IS who they say they are? No, just as you can't prove the hot chick sending you pictures on Facebook isn't in all reality a fat tub of lard.

I do have a demo unit. I do have a Sharp screen. So by the very fact your information from a claimed "source" has been proven wrong by at least one person, means your informant most likely is incorrect and full of crap. Of course you can have a bad screen - but to make such statements that you are making here is just ridiculous.
[Xperia Z General] Slim Shady:
see jerdog buddy first thing i am not trying to prove anything here second even i have bought a xz last week with mfg date of feb and i have jdc as well and third i also wanted to be clear about the display issue of of xz as what's the deal with it found some info about it on thinkdigit forums so i posted here so we can have discussion about it.Since guys at xda are pretty knowledgeable i thought they must be knowing something abt it.But the entire post originally made by the guy who's a sony rep is not entirely wrong there is a panel lottery kind of system here isn't it.Some have got jdc and same have got sharp panel and just cause' one statement is not true does'nt make the whole explanation or post full of crap,ridiculous or wrong my friend and as far as the thing goes for legit source why would sony make a statement themselves that they have screwed up the display panel for their flagship phone it is equal to defamation and would discourage customers from buying their phones as they have kind of a panel lottery system which is true since i have personally seen those demo units and they had the worst display i have ever seen on a phone.

P.S

since u do have a xz with sharp panel have u noticed any difference between jdc and sharp panel if u had to chance to demo an xz with jdc panel ???
[Xperia Z General] jonmorris:
My review unit, given to me at MWC, is a Sharp panel.
[Xperia Z General] lilstevie:
Where does it say he is a sony rep though? is there another post on another board? cause all I see is someone regurgitating information obtained here from Entropy, then some random stuff with no source.
[Xperia Z General] Entropy512:
Did you typo that? since I basically have done nothing and said nothing in regards to displays and panels other than that I'm quite happy with my Z's display.
[Xperia Z General] ethan3686:
Well all i cn say is that i am from india and i do find the contrast much better than what i see in the EU versions in YT

OMG..JDC looks so good with better contrast..sharp is also good but low contrast...Mine is JDC too :fingers-crossed: You can clearly see the difference in blacks.
[Xperia Z General] tilty5280:
Awesome!

Gave my thanks! :D
[Xperia Z General] ethan3686:
Yours is JDC too?
[Xperia Z General] girish1in:
I think it's possible, Docomo xz has much better looking screen with same hardware. That means it's calibrated better.

I am eagerly waiting for 4.2 update which will bring Screen calibration app on XperiaZ
[Xperia Z General] Slim Shady:
Well is there any calibration app for saturation ???
[Xperia Z General] C1emen7s:
I have the JDC screen after I got my old faulty phone replaced. i believe the previous one may have been a sharp screen as watching movies, etc. blacks were deep and accurately replicated. On this one, the JDC screen, blacks are blue and not particularly dark, the screen is almost fuzzy looking and everything is much lighter, just very poor contrast and viewing angles are worse.

Is this justification to take it back to get it replaced?
[Xperia Z General] Ame123:
I dont think that hes saying anything wrong..i have an xperia z and the screen is gorgeus...except for the viewing angles..the blacks are veryyyyy close to the blacks of iphone 5 which has the best display ever..
[Xperia Z General] cmsbfent:
Heres a quick photo of my Z, which I think clears up any doubt that we need a black theme overall as opposed to the grey we have now. The blacks are really nice and the screen would look absolutely stunning if sony would just give us what we need. Also goes a long way in eliminating the viewing angle problem I think??

Simple photo taken with my 4s, completely untouched. Xperia was just lay on the couch next to me ( Loving the xperia Z by the way :good: )

EDIT: I cant link to the pic due to being a new user, grrrr - anyone know a way of showing it?

Also, a good way to show how the bravia engine changes things for the better is to go to your home screen, take a screen (hold power key down - take screenshot) and switch between to photo and back to the home screen. Definate changes in constrast and colurs that, again, seem to help with viewing angles/screen washing

And hello by the way, nice forum :)
[Xperia Z General] NewForce:
I bet many hope on Sony Xperia Z, and when it is finally here Singapore retail stores, I was simply STUNT!

I am truly STUNT Sony Xperia Z screen quality was way below par with today cellphone standard.

The color are not as vibrant as HTC One-X, Butterfly, it is even worst than an iphone.

The viewing anlge are so bad that all colors now coated with a white backlight layer.

e-IPS? LTPS? To me Xperia Z screen look much more like an old TN screen.

I would rather trade-off the water-proof feature for a better screen.

To me screen was the most important component on large screen cellphone.
[Xperia Z General] cmsbfent:
Heres the picture:

[/IMG]

The difference is huge and if the stock colour changed from grey to black, I think the bad reviews about the screen would stop. the grey colour is used throughout the phones interface, and is even there when you power the phone up. Certainly an interesting choice by sony to use it?
[Xperia Z General] Lulabby:
I agree with you. The XZ display black color is not that bad, the bad thing is Sony choose the grey interface which make people think the display is bad.
[Xperia Z General] cmsbfent:
Ive just made a black background for the phone and made a screenshot of the homescreen. Then, I uploaded that screenshot onto my iphones camera roll. So, both phones have the exact same image showing

Whilst admittedly not as good on the xperia in some ways, its far from bad. Still washes out slightly in comparison, but looks a lot better now most of the screen is black. The same video playback on both phones though, and the xperia looks a lot better. Same with other photos once the bravia kicks in

A little contrast tweak and Im almost certain the 2 phones would start to look identical in normal use
[Xperia Z General] Psychomohd:
thanks man
[Xperia Z General] iDroid8:
I haven't heard aby confirmation that the 4.2 update will bring a screen calibration app, source?
[Xperia Z General] Seaclean:
Sv: Clearing up the display issue of the Xperia Z

This. I haven't heard anything about this?
[Xperia Z General] belek1979:
it's not a theme issue, fanboys!

there is no real white in google maps, hd landscapes looks awful comparing to an averange xperia s (no matter BE is on or off)... well, at last, screens that ive seen

What kind of display i have?
[Xperia Z General] little_prince:
Use the apk or restart and do it again, sometimes it takes several reboots to work
[Xperia Z General] cybershock:
I've found this on a Turkish forum,

Two XZs have different displays, JDC(left) and SHARP(right), and they both use the same firmware, check it out.

But the owner of them told that one of them has a BE2 problem which does not effect whether on or off, then he would try to replace it.
[Xperia Z General] kpavl01:
I still don't understand. JVC is better than Sharp, but regardless what display we got, will there be a way to calibrate display or something like that and get it to look better?

Will it be in the future updates?

I am considering this phone, but the display is the my main concern. Because all people I asked from my country (only T-mobile has this phone) got the Sharp display, I am beggining to count this phone off it it won't be solved.
[Xperia Z General] Nameless One:
I believe you should visit a local store and if a demo unit looks promising enough try and convince the staff to allow you to briefly examine a phone from stock (expressing what your concerns are about the display)

with the understanding that if the display is to your liking then you will buy the unit (generally buying anything sight unseen, i.e. unopened and uninspected, should be avoided where things like displays are concerned).

Also, I you are one of those people who are so vulnerable to the power of suggestion that someone with mere words can turn you against something that you had no problems with and up to that point were enjoying,

then avoid posts dealing with opinions of the phone. Also avoid threads about other phones, if you are happy with it then avoid getting fooled

by posts suggesting something else is "better", if you are happy with what you have then everything else is irrelevant and besides, until you get one of the "better" phones in your hands to see for yourself then what others say is basically

just trolling.
[Xperia Z General] drsoran2:
Once you go Full HD on a smartphone screen, there's no turning back. It's simply awesomely sharp. Since I have the XZ, everything else seems blurry like old wallpapers from my S2, my laptop, etc. Now I really know what sharp means! This is one of the positive "disadvantages" of the XZ.
[Xperia Z General] ST4YSTR0NG:
Screen brightness

Ive had my Xperia Z for more than 14 days now and I love almost everything about it.

Sometimes the screen brightness feels dimmed (Im not sure if its just my eyes) although I have automatic brightness setting turned off. Any pointers on that one?
[Xperia Z General] ST4YSTR0NG:
No one?
[Xperia Z General] alexp999:
Mine only auto dims if it is left without user input for a bit.

Without auto brightness it will also feel comparatively dim in bright light unless you change it yourself.
[Xperia Z General] Super Chimp:
Isn't the latest firmware being now pushed out by Sony supposed to improve the screen quality?
[Xperia Z General] GodShapedHole:
.253 improves contrast and black levels by quite a bit. Incredibly, it even helps with viewing angles. I'm going to go ahead and say that it's still not the best display on the market, but this update has turned an OK display into a pretty good display.
[Xperia Z General] Super Chimp:
It improves the viewing angles now that is impressive. Thanks for the feedback.

Surprised as a general point it is still on 4.1.2.
[Xperia Z General] Wahad:
Pictures, please pictures :D
[Xperia Z General] BR4DOKYBrazil:
Greatly improved image quality with this latest update!

Incredible!
[Xperia Z General] pan.tadeusz:
Yesterday I was looking for differences between 441ppi in Z and 323ppi in T - I did not notice :cyclops:
[Xperia Z General] ST4YSTR0NG:
What kind of differences were you looking for? And what did you not notice? :p
[Xperia Z General] pan.tadeusz:
there are many opinions that jump from 1280 to 1920 on mobile is perceptible - I did not notice the difference in resolution
[Xperia Z General] cordonbleu:
Well, I do see the difference between 720p and 1080p. Especially small text on browsing looks much sharper and everything looks smoother.
[Xperia Z General] pan.tadeusz:
I'm wondering how small this text should be... because I was looking websites and didnt see difrce.

ofcs there is difrce in fps loose if it's 1920 vs 1280 - more important I think
[Xperia Z General] skyalvinlee:
A theory i think that is quite viable is that sony intentionally decrease the display quality so that their bravia engine actually makes a difference, it the Z had a perfect screen with perfect colors, their bravia engine would be null and the Z would have one less selling point.:silly:
[Xperia Z General] msc3169:
By using this display Sony has kept down its manufacturing costs which for them translates to bigger profits and if you look at their financial condition, they were operating at a loss until recently. Its when the company is financially stable can they put more resources into better hardware.
[Xperia Z General] Tiamath99:
I frankly don't thing that is possibly. You are talking about parameters that are calibrated at the factory and not by software.

Although it's true that via software you can tweak things a little bit, they are not near enough to make a difference in the huge hole that are the defects on the display itself.

And about the display...what is a good display? Varies, What was considered a good display a year ago maybe it's mediocre now.

Being one of the first 1080 display made a difference in detail when the Z first was released, but it's horrible viewing angles, weak colors, washed out blacks with that feeble contrasts make it one of the worst 1080 displays out there in the market.

Just my opinion.
[Xperia Z General] MARKOZD15:
Hello!

as far as I can see, the Docomo version of XZ have better colors and viewing angles... If it's only a difference in kernel, could I flash the Docomo kernel on my Xperia Z (C6603), will I brick the device?
[Xperia Z General] Riyal:
A hard bump for this thread! :D Well since I'm gonna ask some LCD question for Z owners.

Can someone here with a Xperia Z post their touch firmware version here?

To do so please open your phone app and type

*#*#7378423#*#* or *#*#SERVICE#*#*

then navigate to Service info->Firmware Info

Then post here the Synaptics Clearpad touch firmware information you have on your device? It should look like this...

I would really appreciate it if someone can post theirs.

[Xperia Z General] stefanve:
the problem with looking at photo's of screens is that there are to much things that can interfere with correctly displaying what one can see with there own eyes.

The camera used adds it's own color signature, distortions, fuzzynes etc, this has mostley to do with the lens and the sensor

Then it needs to be converted, this is done either in camera, so than you get the interpretation of the image processor of the camera. Or the photographer processes a raw image, than you are at the mercy of the skills from the photographer and if he has a calibrate screen and knows how to work with color management.

Than you will see it on your screen and unless the photographer has done a good job with the RAW image and you have a correctly calibrated srgb screen it's highly doubtful that the photos will give a correct representation of what is been seen.

That being said, the XZ doesn't have a bad screen but it is not on par with the competition so in the end it is up to you if you find it god enough or if you could can't life with the fact that there are better screens out there :)
[Xperia Z General] Shasarak:
You can't tell anything useful from a photo or a video. There are too many unknown factors involved with the camera that took the picture. If its exposure is set high, the phone will look like it has poor black level; if it's set low it'll look like the screen is too dark; and the white balance and colour saturation will likely be misrepresented by the camera too, in unknowable ways. And on top of that, unless the monitor screen you're looking at the photograph on has been callibrated accurately, that will introduce another set of errors in the colour balance.

The only time a photo or video is remotely useful is when it allows you to compare two different things in the same frame or clip. For example, it can show you that one display has a colour balance that is more red or more blue than another (but can't tell you which of the two is actually nearer to being correct); or it can allow you to compare the black levels of multiple phones and see which one is best out of the group.

EDIT: ninja'ed. :(
[Xperia Z General] Kurowsk1:
Just been to the three store in Newcastle and to be honest, at least compared to the galaxy s3 next to it and my iphone 4, the screen was fantastic.
[Xperia Z General] Kallb123:
Coming from an X10, the screen looks great. I've used a One X before and I wouldn't say this is significantly different to my eyes. Like what others have said, the UI is much greyer which did make it seem washed out, but when you look at icons and bits of proper colour, it looks fine (fine colour-wise, but the resolution is superb) :)
[Xperia Z General] mwatson:
I've just played with a demo Xperia Z in a shop today and there is nothing wrong with the screen at all! I think people are getting carried away with scientific measurements and getting hung up on it. Judge it with your eyeballs.. The screen looks great!

Can some one explain to me the hang up with viewing angles? This is a mobile phone not the living room TV FFS! do people like to look at their phones from 45 degree angles from the side? I look at mine head on. Is it because you might want to show some friends a video? realistically how many people can gather round a watch a 5 inch screen? will any of those friends be thinking " thats a crap phone.. the viewing angles are not good!" of course not. Its a mobile phone!!
[Xperia Z General] m00moo:
WE HAVE checked with our eyeballs and it does appear washed out.
[Xperia Z General] Phorgasmic:
washed out doesnt mean 'not oversaturated' tough... just saying. i got mine at home today, will see soon. on pics it doesnt look washed out.
[Xperia Z General] stefanve:
Well to each his own some people like it some don't, some hold higher values than others and like said before it depends on what your previous phone was.
[Xperia Z General] Maedhros:
I disagree, compared a ZL side to side with the NA One X and there is a noticeable difference in screen quality.

The One X blows it away unfortunately.

Refuse to believe if you would like, and enjoy your purchase for what it is.
[Xperia Z General] m00moo:
Yes but he said we aren't judging it properly which he is wrong. We are judging it with our own eyes and isn't that proper enough? It it really wasn't a problem do you think people would even be talking about it? Even at low low brightness the screen to me looked very backlit grey. This means at a higher brightness levels the greys simply turnt more lighter grey. Hopefully this kernel stuff can fix it.
[Xperia Z General] Kallb123:
Take into account the UI colours too. When I used it today I opened up the app drawer and thought "Hmmm, it is a little washed out" but then I noticed that there's a grey background and looking at the details proved to me that the screen was well above adequate for me.
[Xperia Z General] Phorgasmic:
sure there are better displays out there i wont argue. coming from a S2, i think i will be greatly pleasured with the screen :)
[Xperia Z General] m00moo:
I took that into account. I googled black images which didn't give me the relieving Phew! its ok. They still appeared dull grey :( maybe they are differences in stock, i don't know but from what i saw personally i wasn't gob smacked. I have still got my pre order though and if i don't like it i will just sell it on.
[Xperia Z General] stefanve:
I think that was his point....
