At last, an expert on that case. Great ! Can't wait to know what's going on.
[Xperia Z General] The things I tell you:
The white haze you see on the Z screen is a sign of contrast level being too low. On most Windows PCs you can right-click on a jpeg, select "Edit" and then lower the contrast to see this in effect. Although, on my Z, contrast doesn't seem to be as low as it is in some of the photos posted.

There's nothing wrong with the screen itself - it's not a hardware problem. The contrast just needs to go up a bit - something which Sony could put in an update or, even better, provide a tool so one can adjust it to personal preference. We can see what the screen is capable of when the Bravia engine kicks in when viewing an image in the album - the contrast just goes up to a mid-level where it should be and the images look excellent. Putting the contrast at a lower level was probably just a cynical attempt by Sony to make you say "wow!" when using the bravia engine, just manufacturing an exaggerated difference. We don't need a "better" screen, we just need the contrast to be put up to the correct level on the screen we have.
[Xperia Z General] lloydbf:
Contrast is a tradeoff between brightness and black level.

There is no magic fix to increase contrast apart from properly calibrating it to get the most out of the HARDware.
[Xperia Z General] itsmemuffins:
The screen on this one looks excellent. I have seen videos where the screen looked very sub par:confused:

[youtube]AvWGATIMa9Y[/youtube]
[Xperia Z General] sacredsoul:
Any idea when we will get the calibration software?
[Xperia Z General] vineet09:
woah!! your xz has a great screen and nice viewing angles..Could you share some details(i dunno which) that will help me to compare mine with yours??
[Xperia Z General] itsmemuffins:
I wish that was mine. My screen it total ****e.

Phone arrived this morning and now it's back in its box ready to go back.

Yuck, what was Sony thinking with that screen. Looks like the screen from the Htc Titan only difference is the resolution.

Having and iPad 3 and and iPhone 5 I can't put up with the Xperia Z screen. Not for one moment.
[Xperia Z General] subcode:
Definitely Sony uses different panels... Mine is good only when i look the phone straight. Sony should be clear about this problem and rectify it.
[Xperia Z General] jonmorris:
Besides letting you adjust some settings, or having some presets, I can't see Sony changing the screen simply because some people think it's

so

bad it isn't worth keeping the phone.

I expect the majority of people will think the screen is just fine, especially when using apps that invoke the BE2 engine.

Some will be disappointed by the theme choices and the use of grey, and not immediately realise that in display you have a slider for brightness and an option to adjust for conditions. On most devices, that option is 'auto brightness' and I expect a few will be caught out here. If they leave the slider on the lowest (or highest) they'll see an incredibly dark screen all the time with minor adjustments, or a full-power one that kills the battery all the time.

That's the way it works on the iPhone too, mind you (and other Xperia devices that didn't have the option, like the XS), but I still think a lot of people are perhaps ending up with a pretty poor image from not realising you may need to adapt the overall brightness for different conditions every now and then.
[Xperia Z General] lee480:
In my perspective, the screen is horrible. There's a wash out look everywhere. It's proven numerous times. Though I won't blame Xperia Z users. Xperia Z is indeed a great phone. All its pro outweighs its cons.

Though the screen isn't Sony's best, unfortunately.
[Xperia Z General] Riyal:
Plastic tend to flex while glass is fragile. Sure glass could survive a drop on a material where it is harder but I highly doubt it if it were to be dropped on a metal/concrete surface. Impact would create a deep shock on it's body and I don't think any glass could survive that. Since glasses are pretty solid and doesn't really have any shock absorbent property on it.

Maybe we would have to wait for a drop test video of gizmoslip for the Xperia Z/ZL :D
[Xperia Z General] stefanve:
Yes please someone with a z try this out :)
[Xperia Z General] maverick1103:
2nd that, this could be a big game change!
[Xperia Z General] ethan3686:
Seriously anyone with a XZ should try this and post some results too with screenshots!
[Xperia Z General] craftycarper1:
This will be the deal breaker for me......patiently waiting some feedback about this, i like the screen, but for 2 years?....not so sure......i got my One X on a 12 month contract and was hoping to do the same with the Z.........but none about.

If this app makes no difference whatsoever then i will probably be pre ordering the M7/One when details come out about contracts.
[Xperia Z General] stefanve:
Indeed, although I'm kinda worried about the battery life of the M7 since everyone says the One X has a rubbish battery life. It could be a trade off i'm willing to make as the display is as step up from what I have now, would be far more difficult if it was a step down :)
[Xperia Z General] craftycarper1:
One X running custom ROMs give good battery life.....i regularly get 2+ days out of mine, light to medium usage.....in fact i have had over 4 days from my battery, only 2hrs screen on time, but still, good battery stats can easily be achieved. I am not a heavy gamer, but once i initially got over the "new phone" period with my One X, the battery became easily more manageable, and i would expect the same to be true for the M7.

Also the battery should be quite easy to change for one of a higher capacity, as many are now doing with the One X, changing the battery for the higher output one from the X+.
[Xperia Z General] Ambroos:
Tried, but the best way by far is default (without the app). Changing any value just decreases the contrast or throws off the colour balance.
[Xperia Z General] stefanve:
Thanks, in the end it would still be possible since the bravia engine manage to get more vibrant colors from the display. sure would have been nice to get that without lo level trickery
[Xperia Z General] Ambroos:
Bravia Engine just increases the saturation of images.

This actually is a good thing. It means that the Xperia Z is a nuanced display that doesn't do a cutoff but actually is capable of displaying all the colour gradations properly. The display is fine, I don't know how many times I have to keep repeating it. The only 'problem' with the Xperia Z is that the UI uses a lot of greys, causing everything to look a bit dull, especially with higher brightness settings. Colours are pretty deep and accurate.
[Xperia Z General] stefanve:
Yeah I have to see it my self, some people think that my TV looks dull while it is near perfectly calibrated but these days some people are used to highly over saturated un natural color palettes. It's just like with food, eat enough highly salty or sweet food and every thing else seems tasteless :)
[Xperia Z General] Ambroos:
Exactly. I work on a Vaio Z with a very accurate colour reproduction myself, a display that has been praised numerous times for being very high quality and I hardly notice any difference in reproduction with my Xperia Z (without Bravia Engine), unlike all other phones I've seen before. I'm very pleased!
[Xperia Z General] Kurowsk1:
I'm going to head to the 3 shop in Newcastle today to have another play with the device. This screen issue is driving me up the wall!
[Xperia Z General] Shasarak:
Really? The only detailed colorimeter analysis of the XZ screen that I've seen wasn't exactly flattering. See slides 5-12, here: http://www.phonearena.com/news/Scre...ows-almost-perfect-calibration-by-HTC_id39893 The colour temperature swings all over the place as you move across the grey-scale (and is, on average, too blue); and red and green primaries are decidedly over-saturated (the Butterfly does a far better job of both, but is a bit weaker in terms of gamma accuracy).

Reviews consistently point to a poor black-level, too; for example: http://www.gsmarena.com/sony_xperia_z-review-887p3.php or here (third photo): http://www.frandroid.com/test/128142_sony-xperia-z-test-smartphone-android/3/
[Xperia Z General] stefanve:
I think it is clear that the z uses the lesser screen tech, but perhaps also less power hungry.

For me the question is how much worse is it, if it is a a big a difference with the xt I would be disappointed. But than again if the leaked specs are true of the m7 it would be a very power hungry device with a relatively weak battery and that could be the deciding factor for me.
[Xperia Z General] dibdin:
It was mentioned by a member on this forum who has the T that he/she could see little to no difference when comparing both devices. Have to say I was somewhat disappointed in hearing that.
[Xperia Z General] z.o.cc:
LTPS is a description of a manufacturing process, not a display technology. Low-temperature polycrystalline silicon can be used to make different types of screens – AMOLED as well as standard LCDs. It’s a way of creating tiny silicon crystals that go into making the pixels of a display.

I guess samsung use LTPS to make the flexible amoled display.

the LCD family are TN, VA and IPS and the Xperia Z/ZL probably is a kind of e-IPS display because pro and cons are typialc of this display family.
[Xperia Z General] stefanve:
http://hi-tech.mail.ru/review/misc/Sony_Xperia_Z-rev.html

this one has even more detail, it's in Russian but readable with translate.google.com

I should note that they report a contrast ratio of 570:1 nearly the same as gsmarena first reported than changed it to 700:1.

Also they say that the screen of the HTC butterfly is miles better than the Z, but again they would choose the Z over the butterfly. Almost every review says it's the best on the market so it must do allot of things right to get that label in spite of it's sub par screen.
[Xperia Z General] Kurowsk1:
Screen looks just as good in every photo apart from the extreme viewing angle on that site though?
[Xperia Z General] samxool:
EXPLAIN why in chrome, whites don't look white until you turn the brightness way up.

But by turning the brightness way up, blacks no longer black, but all washed out.

and vice versa when you decrease birghtness.

The display is washed out, I don't know how many times I have to keep repeating it.
[Xperia Z General] dibdin:
I find it to be a noticeable improvement over the Xperia S. Blacks are deeper, whites appear to be whiter. Thankfully no sign of yellow tint/gradient that plagued early batches of the Xperia S. My last 2 phones before the Z were the Arc and the S, so maybe my eyes have become accustomed to Sony/Ericsson displays.

I am well aware that the display on the Z is not in the same class as LCD3 like on the Butterfly or the HTC One, but I am more tab happy with the display on my unit.
[Xperia Z General] maverick1103:
Totally agree, I much prefer the accurate colours from the XZ, compared to my last Samsung devices, plus it's much easier on the eyes imo!
[Xperia Z General] itsmemuffins:
Out of interest. Those that think the display I'd great, did it come with chrome and a built in browser?

I'm no expert, but you may have a Sharp screen? We'll need more samples from other Z owners.
[Xperia Z General] Ape187:
That's what I think too. The colors are great and blacks are black. It washes out when I tilt my phone though. All in all I'm happy with it.
[Xperia Z General] vineet09:
That might be happening coz screen is TFT not an IPS panel(like iphone) or Super LCD3(htc one).
[Xperia Z General] Ape187:
Yup, i already knew that. :) I expected worse from it, but it turned out quite well. It's nothing compared to my One X in terms of viewing angle, but I don't mind.
[Xperia Z General] arlaken:
Just wanted to add to this thread, I'm pretty satisfied with the screen. Yes the viewing angles aren't great, but... who needs viewing angles? I "certainly" want to share what I'm looking at to stangers... :P

I think those who are complaining about the screen are forgetting that this is a 1080P screen... there is as much pixels on this phone then on your TV at home. The poor viewing angle is because the screen is a TFT LCD. Though it is a old technology, if has never been cranked up with such a density. But since its a well known technology, its cost isn't as substantial then a AMOLED screen. The cost of a AMOLED screen with such a density would be enormous, and the price of the phone is already pretty high.

So, I think Sony made a wise decision. The viewing angle and lower contrast is a small tradeoff for what we gain with having a 1080P screen.
[Xperia Z General] jonmorris:
I think most people will be, simply because most people won't have another device next to it to make any sort of comparison.

My Razr i screen, being OLED, has a green tint on white backgrounds whenever the brightness is turned down. However, your eyes compensate for a lot of things and I never saw it as a problem.

Of course, in terms of someone reviewing the screen in-depth, it's awful. And if I put it next to my Nexus 4 or Xperia Z - or, frankly, any other phone with an LCD display, you can suddenly see it quite obviously.

But as I don't do that all the time, I still think the display is generally very good.

It will be interesting to see if Samsung uses OLED on the Galaxy S4. I believe it will and wonder how good the screen will be, and if it will be a PenTile matrix (of course, at that resolution you might not notice) etc.

I also wonder what the colours will be like, given Samsung prefers to over saturate colours (by default) because they look more vivid and a lot of people equate that with better quality, rather than muted colours that are actually more lifelike.

Nobody will ever make a screen to suit all tastes, but Sony could satisfy a lot more people by giving some sort of control of the screen settings - just as Samsung does, even if a lot of users never adjust them. You can make a Samsung OLED screen look a lot better from the settings menu, so why can't Sony do the same?
[Xperia Z General] randomuseresato:
Don't mean to be rude but please go and read up about LCD screens a bit. TFT is not a panel type!!!. TFT is the backplane used in almost ALL LCD panels. IPS panels also use TFT backplane.

There are three types of LCD panels mainly - TN, VA and IPS. Z uses IPS. TN is what you find in phones like Xperia Tipo. VA is not used in phones.

Another Sharp screen.
[Xperia Z General] vineet09:
Viewing angles don't matter much on a mobile screen. It's a slight issue.

As I see this thread has 2 parts - one is washed out colors which can be rectified by Sony in a future update. 2nd is viewing angle that is the characteristic of TFT Lcds not IPS.

gsmarena, phonarena & even Sony mention TFT not IPS under display specs. Reading many posts above most here think it's TFT technology that's used in XZ.
[Xperia Z General] Ape187:
Hmm, okay. So it's save to say that there are at least two different panels for the Xperia Z? And the interesting part would be, which panel is better...

edit: forgot to say, my phone is a german unbranded one
[Xperia Z General] galuquetta:

[Xperia Z General] LordManhattan:

[Xperia Z General] lloydbf:
Might I ask how you rooted your Vodafone handset? It should have a locked bootloader surely?
[Xperia Z General] Ape187:
The colors look great and the blacks are pretty deep too, if I face it head on (not washed out at all), but if I tilt it about 30 degrees on either side, it washes out pretty fast. I think that's to be expected of an e-IPS panel. I set the brightness to about 30-40% and adapt to lightning conditions is ticked.
[Xperia Z General] lloydbf:
It would be really helpful if people specify which colour their phone is (black or white). In regards to posting the panel.

As I've noticed several times now that white Z has a much darker screen.

What? Are you being serious? If the screen is "blue" then why don't they edit the entire system to change everything to "red" if they "can" do that to a video? If the screen is capable of displaying that color then it's a calibration issue.

I don't care if the phone has a problem but it its obvious you are trolling

[Xperia Z General] LordManhattan:
We aren't 100% sure yet. Is your display good? Deep blacks and "OK" viewing angles?

I wouldn't count on it, but they may push it to their dev site and offer it as a stand alone APK, so devs and other people can sideload it on their device. Why would the average user be interested in calibration?

I may be waaaay off now, and this is just a thought; not fact.

BTW, send Sony an email and ask them straight out. It'll probably take them a couple of days or weeks but that just the way it is. They replies me after a week about my question about using two display manufacturers (which they denied).

I have a question, wasn't this screen supposed to be exactly the same as the Oppo find 5, the Sharp model.

If so, and considering that the Oppo screen is much better in terms of viewing angles contrast and colors, could it be possible that all be a problem of bad calibration of the screen?

[Xperia Z General] hurkshal:
The XZ panel manufactured by Sharp has the CG-Silicon technology, it is a display with very thin layers.

This technology not include IPS because CG-Silicon viewing angles is similarly high, I think around 160 degrees.
[Xperia Z General] Hollowpoint:
I'm confused, how does screen calibration result into better viewing angles? Aren't viewing angles tied to the type of panel/display technology and application?
