that's true. if Sony were to use non-triluminous screens and claim they were, they would receive great backlash.

I'm pretty sure they are not that stupid. :eek:
[Xperia Z1 General] TheCraig:
Highly unlikely that they give you a screen other than a triluminous.
[Xperia Z1 General] Why So Serious?:
Guys, just to be clear... Triluminous isn't a type of screen... It's Sony's brand name for quantam dot backlighting, which is a fairly new technology used in place of traditional white led backlighting.

As far as I'm aware, It could be used with a TN panel, an IPS panel, VA, Super PLS... Etc. All of which are TFT lcds.

A lot of people seem to be arguing and comparing the wrong things so it's important to get the facts right. I hope all of the retail models ship with IPS or super PLS screens.
[Xperia Z1 General] cruzzade:
Either way it's not like you could just swap out the old Xperia Z back lightning and slab on a triluminous light system to the old LCD-displays in stock.
[Xperia Z1 General] pesho00:
I saw preproduction model and IMHO it is exactley the same display as my old Z. I have no idea wheter retail devices will have different displays.
[Xperia Z1 General] Geoffxx:
The only retail version of the phone tested was GSMA the rest are preproduction or prototypes so this thread is complete rubbish - plus the XZ screen will not work properly in the Z1 without extensive reworking and anyone that has ever been involved in manufacturing or design will know that reworking is not an option, so far all of the genuine reviews using proven retail versions of the phone have had the same screen as the XZU - someone close this thread for stpidity
[Xperia Z1 General] dw1llow:
Triluminos is just blue LED backlight with red/green quantum dots on the panel, so it can be produced by modifying on TN base?
[Xperia Z1 General] japjit100:
In gsmarena listed as tft screen

So this discussion is use less

http://m.gsmarena.com/sony_xperia_z1-5596.php

I see so many video's of Sony xperia z1 in video screen looks same
[Xperia Z1 General] DarrenT:
Well I can at least take a macro shot of my screen to see what the pixel arrangement is.
[Xperia Z1 General] krispijn_s:
LOL. I was thinking the exact same thing. I'd be shocked/surprised if it looks different from the XZU.

Now all I need is the phone; come on pre-order!.
[Xperia Z1 General] jos_031:
But that will be additional labor and will cost them more than getting new display. for prototyping it is ok. they can use it in low end devices
[Xperia Z1 General] cruzzade:
"Just blue LED backlight..."? Do you think that an LCD screen is made of two thick independent layers which can easily be separated and swapped? It would be much simpler and cheaper to just make new displays.
[Xperia Z1 General] dw1llow:
lol chill out man, i was asking a question, not a statement.

Well I just hope the screen isn't as bad as it's rumoured to be. Cus I'm starting to get this uneasy feeling, maybe I should have preordered note3 instead... or even wait for Z2 with IPS Triluminos
[Xperia Z1 General] jos_031:
Z2 is rumored to have IGZO not ips... the main advantage is less power consumption...
[Xperia Z1 General] cruzzade:
I reckon this is just a huge overblown rumour created by the thread starter :)
[Xperia Z1 General] dw1llow:
yep. I definitely pulled my trigger too early for Z1. I knew it...
[Xperia Z1 General] Mazzstrikers:
No. We clearly are not fanboys in case you feel it is a placebo. Many of us have owned multiple phones and have either owned or considered Sony at one point in time.

Whether you like them or not, it is laid out with clear evidence that they cheaped out in the screen of the Z1. We wouldn't need to overstate the problem with viewing angles because anyone who has seen a demo in store or owned any previous Xperia would know. And I already owned an Arc, and Xperia S to know this is an inherent problem they have never quite overcame, confirmed after I saw the demo of the Z1.

It's also not that we nitpick. Sony smartphones in Q4 of the year have got almost everything right. But the display of the phone is what makes the biggest first impression. Even if many claim that one need not view the screen off angle, when you place the phone on a table the display washes out. Your friends will easily comment that the screen is sub-par, which is something you wouldn't want when you pay top dollar for a smartphone.
[Xperia Z1 General] marc_ecko28:
On the otherhand, people who wants to install privacy screen protector doesnt need it anymore... :D
[Xperia Z1 General] Mazzstrikers:
Hey I thought of that too! Even better, install a privacy screen protector and pass it off as a privacy thing such that people do not realise the poor viewing angles! :thumbup:
[Xperia Z1 General] For_itembine:
The verge, engadget etc need to chat to the CEO about there poor viewing angles. They must know when they compare it to other phones. Why didn't they use the same display as in the ultra?.
[Xperia Z1 General] Mazzstrikers:
The CEO probably knows. It's a company decision to source for poor panels. Considering the Z Ultra got a really good panel we wonder why are they intentionally sabotaging the Z1. Or is it that they think people won't notice or don't care. Either way they are dead wrong.
[Xperia Z1 General] marc_ecko28:
Actually Im making fun of it.

But honestly thats make sense...

Anyway when the screen is on home and app drawer if you look at it on different angles its a bit washed out, but I noticed when I watch Movies, browse pics and on gaming, viewing angles are better. Maybe because of the xreality is enabled and it really helps. (i know xreality wont work on games and other non sony apps)
[Xperia Z1 General] Johann_London:
No I disagree. I came from an IPhone 5 which had perfect viewing angles.

The fact of the matter is the Z1, which I otherwise love by the way, has the poorest viewing angles of any flagship phone out there.

I hate how the colours wash out when I sit next to a friend and he is browsing through YouTube and showing me videos...

It's just way, way below the S4, the G2, the iPhone, Nokia 's offerings and of course the display leader, the HTC One...
[Xperia Z1 General] Mazzstrikers:
Nuff said. My sentiments exactly.
[Xperia Z1 General] stilex:
It's this way so the Z2 has the best screen.. more $$$ hahaha
[Xperia Z1 General] Dpk1:
I think the Z1 screen has better sunlight legibility & colour accuracy than Z ultra screen. So, all is not lost for the Z1 screen (save for the viewing angles). Sony doesn't have a perfect screen on Z ultra either, although it does seem to have better perceived contrast & punchy colours (being IPS display). I compared both screens closely and find Z1 screen to show better details on any photo (especially in darker areas) compared to Z ultra & even in videos. Hence, a better screen imo would be one with best of both (Z1 & ultra) or in short Z1 with good viewing angles!

[MENTION=225651]op[/MENTION] : To the best of my knowledge, I didn't find anybody here with a Z1 screen other than renesas sharp. So, maybe this "display lottery" thing is a hoax. So, time to rename or edit the thread title don't you think?
[Xperia Z1 General] ruchirtrehan:
You need to learn how to read, I said fanboys of 'viewing angles' which are basically to hold phone in an odd angle and see if anything is visible or not and no one in world will use the phone like that for more than 1 min, also go and learn about tech, a non super amoled/IPS panel can be 'waterproof' but super amoled and IPS "cannot" be waterproof and if you say me it has nothing to with it, better be out of here and learn about it, also if you seriously think a phone shall come with (even a flagship) with no minor issues, I guess it's time you start manufacturing your's own brand. I am not defending Sony, but you need to learn how technology is used, at the moment if you want Sony to have amoled and IPS better be ready to sacrifice waterproof-ness, again it can mostly be a personal preference what a individual likes to see.

---------- Post added at 06:15 AM ---------- Previous post was at 06:14 AM ----------

Even I am watching videos with 5-6 of my friends on z1, color's do not washout by any way, maybe you're just unlucky in early batches and I am too lucky.
[Xperia Z1 General] Mazzstrikers:
Dude you are telling me to learn about tech now? What does waterproofing have to do with the screen technology? IPS or AMOLED they are just different screen technologies! Waterproofing is about the physical design of the phone such that there are no gaps and it is properly sealed in operation such that no water can enter. They are two irrelevant matters.

Case in point is the Xperia Z Ultra which uses the IPS panel and offers the viewing angles and is waterproof AT THE SAME TIME. So you just contradicted yourself. Who says they can't co-exist?

Lastly I am also not a fanboy of viewing angles. I don't view the screen off angle for long periods of time too. But I've owned an Arc and when I place it on a table and a message comes in, the screen comes on and a friend sees the screen washed out because he doesn't view it head on so he asks me why my screen is so washed out. For a phone so high tech like the Z1 the screen makes it a less premium experience we would have liked it to be, not that we are bashing the phone in any way so do not take offence.

Finally there is some benefit of the doubt I reserve for you because you are telling me yours looks perfectly alright. However, until I see one that is as good as the Ultra I am still a skeptic.
[Xperia Z1 General] ruchirtrehan:
Seriously? and you say I don't need to tell you about tech? Just answer my simple question then, the whole galaxy s4 series used the super amoled's but only the s4 active which was the only waterproof phone in s4 series did not come with any IPS or amoled why so? Just think with brain and don't get into tech since you'll never know about it, also z1 and z ultra are same panels, the only difference in z1 is early batches, I had myself taken 7 replacements of z1 and after that I finally have a pure device with great viewing angles and perfect display. I from nowhere mean viewing angles 'do not' matter at all, but seeing people saying viewing angles are par ridiculous I am just curious to know if they've even used the device in hand or even after using it they have confused themselves in mind just coz of some fake reviews (goes to every brand such as Sony, LG, Samsung, etc)
[Xperia Z1 General] Mazzstrikers:
Wow I tried to provide an objective discussion and you tell me to use my brain. Bloody hell.

Good for you because I've just confirmed that whatever you have just said is bull****. I told you waterproofing is only about physical design and you are not convinced.

Good for me I've done the Google for you, which you couldn't even be bothered to do before engaging in this flaming.

Now there is still a long list to go but I'm too lazy to copy and paste. Why should I do the googling for you?! Just because your favourite manufacturer Sony doesn't do it right and Samsung too doesn't automatically make it impossible. Think before you generalise to save yourself from some embarassment.

One thing is for sure. SONY XPERIA Z1 display sucks big time. Shame on you SONY for making me keep coming back to your service center with only a promise of a software update fix. You have the worst quality control in the world for your info.
[Xperia Z1 General] Morlock O:
Lol wrong place to say this,nobody really cares if you are not satisfied with your phone... this forum is not related to sony whatsoever.... you can complain to their website or something...

---------- Post added at 10:14 AM ---------- Previous post was at 09:42 AM ----------

Weird the latest flagship of Kyocera also stopped using IPS

http://www.gsmarena.com/kyocera_hydro_elite-5754.php

you actually don't have to look further... our own Sony Z Ultra has waterproof and IPS screen (eIPS not sure whats the difference)

I think there is a trade-off when using Amoled + Waterproof... else Samsung (being the leading manufacturer of this screens) can easily have used in the S4 active... maybe bigger bezels or thicker phone to secure the Amoled better... not too sure... can't seem to find info on it...
[Xperia Z1 General] Mazzstrikers:
Yep! True I also wonder why they didn't use the AMOLED in the S4 Active. But I'm guessing it is more of a profit/cost thing. Reason being the active is kind of a niche device for those who want a waterproof phone with powerful innards like the S4 and as far as I know it is one of the most well specced waterproof phones on the market. So their potential buyers are likely to buy the phone whether the screen is AMOLED or LCD. Same case as with the Galaxy Mega which is equally niche in nature. That is probably the most logical rationale why they are throwing run of the mill LCD panels in them, and less because say, because the active is waterproof.

For the Kyocera it seems kinda weird too. But I'm still guessing it's the same rationale of waterproof phones being niche in nature. This is unlike Sony's approach where they are trying to make waterproof phones the standard and mainstream. That's why they are throwing in powerful processors and stuff.

---------- Post added at 05:46 PM ---------- Previous post was at 05:27 PM ----------

And there's the second possibility. In business firms usually avoid cannibalising the sales of other products in their lineup and that's why they differenciate their products this way.

For example if the S4 Active had an AMOLED panel like in the S4, many consumers would have choosen it over the S4 because it offers the added advantage of being waterproof on top of having similar specs to the S4.

Similarly, Sony threw in a crappy camera module on the Z Ultra to differenciate it from the Z1. Can you imagine how may people would buy the Ultra in a heartbeat if it had the camera of the Z1 together with the awesome screen it currently has? I'm one of them who would gladly accept the monstrous screen size if the camera was Z1 standard.

That's why they usually shortchange some aspect of their phones to make it very clear that say the Z1 is their imaging flagship, and Ultra is their large screen flagship. Consumers are forced to weigh the trade offs and make a decision.
[Xperia Z1 General] Why So Serious?:
Had a look at the Z1 (and Z Ultra) in store this weekend and my first impression of the Z1 display was that it's not as bad as people have been making out.

If you're not coming from another flagship and are upgrading from one of Sony's previous flagships then you'll definitely see an improvement. Even the viewing angles (don't shoot me) are better than their previous flagships, but are admittedly lacking compared to other displays out there now. The ZU which was right next to the Z1 was noticeably better.

Also, on the viewing angles debate... whether one person thinks they're important or not is irrelevant. Clearly some people (including myself) do think they're important and Sony should make sure it has that covered. Reviews are probably more powerful than marketing, and Sony keep shooting themselves in the foot by not offering a best in class (or close to) display.

Hopefully this will be Sony's turning point: JDI announces 1440 x 2560 QuadHD 543 PPI Display

The numbers sound impressive, and the dead band (which will define the bezel size) is tiny. Hopefully the quality and viewing angles are also fantastic.

If HTC and Samsung go early for next year's flagships I don't think they'll be ready for QHD which would leave the door wide open for Sony to steal the show later in the year. LG have also unveiled a 5.5inch QHD display which we can assume will be of fantastic quality so JDI's display needs to be good. If I was CEO of Sony I would be applying as much pressure to JDI as possible to make it happen.
[Xperia Z1 General] Mazzstrikers:
Good point! Improvement I'm quite sure is there but it is hard to justify not having perfect viewing angles in Q4 of 2013. In the era of the Xperia Arc (about 2011) it was looking washed out comparatively to competitors such as the Samsung S2 and iPhone 4/4S just due to viewing angles. Problem is from my use, when viewed head on it is a really good panel which is such a shame.

Failure is not a problem as long as they are quickly able to learn from their mistakes and make a comeback. Remember the HTC Sensation which belongs to the Xperia Arc era? The viewing angles were as bad as the Arc and even viewed head on the colours were so poor that the qHD resolution was useless?

After the poor feedback, they released the next flagship the HTC One X which had one of the best looking 720p panels among the competition. Perfect viewing angles and colour rendition was stellar. I was totally sold on it. Fast forward to 2013, the HTC One has arguably the best screen in the competition if size isn't the issue. They came from the bottom, improved on their traditional weaknesses (screen, camera and speakers) and worked on their strengths (build quality and user friendliness of Sense) to earn a Techradar 5 star rating which I thought was fully deserved.

I keep thinking Sony isn't trying hard enough. They have a great advantage given their expertise and large capital compared to HTC ahich started as a small Taiwan electronics firm. I feel that Sony could have made the best all rounder in 2013 Q4 which is the Z1. It had ALL the elements of it just the screen which prevented it from making a homerun which it deserves.

The JDI you quoted seems an excellent panel. If viewing angles are still a problem no matter how they push for pixel densities (which they were always leading to begin with) they would never make that homerun. Yet if this has that perfect viewing angles, shut up and take my money :thumbup:
[Xperia Z1 General] hoezay:
I find it a little hard to believe that Z1's without the viewing angle washouts exist. I am yet to see an Xperia Z1 that does not wash out / have a yellowish screen. If you have one that displays whites perfectly, please post a picture of your device displaying a fully white screen. If it truly is the case, then your "perfect viewing angles / white screen " Z1 pictures will help pretty much everyone in India get replacements.
[Xperia Z1 General] natkaen:
i just bought a new z1, bh900 hk. at first the white was white. after i upgraded ota to version .534 it got that yellow white. so i think it software.
[Xperia Z1 General] Jiyeon90:
This is what my first unit looked like compared to my acro s

The whites were excellent, even whiter than snow but sadly it had some dead pixels so I got it exchanged

So then I got this one

which is not as white as the first one but you only notice the yellow tint when viewing greys, other than that its unnoticeable.

The funny thing is that I prefer the acro s screen over both Z1s I had, simply coz it displays more vivid colors.

When it comes to viewing angles both Z1s were the same, not as good as the competition but not as bad as some people try to make it look.
[Xperia Z1 General] Mazzstrikers:
Yes that is generally true. What you have on the original Z1 is termed a 'cooler' colour temperature. A white background looks nicely white with a little blue tinge on a 'cool' screen.

Your Arco S has a 'warm' colour temperature whereby white looks slightly yellow. I had an iPhone 4S which has a warm colour temperature whereas most of the 4S I've seen are on the cool side.

Generally the colours on warmer screens tend to look more natural in my opinion. But the slightly yellowish tint needs getting used to.
[Xperia Z1 General] Jiyeon90:
Yeah I never noticed my acro s had warm whites until I compared it side by side to the Z1, it always showed really nice and vivid colors, while on my second Z1 I noticed the yellow hue as soon as I looked at something grey, first one was fine though but still not as vivid as my acro s.

Hopefully sony will release the screen calibration app or some update for the screen, the last update reduced the yellow hue but its not completely gone.
[Xperia Z1 General] jonmorris:
That's because it isn't!

One of the benefits of the screen is that when you look straight on (or almost straight on), the phone has a pretty incredible contrast ratio. No, it isn't AS good as AM-OLED but it's still amazing in my opinion.

If this screen type can only get such good contrast by having the side effect of the colours shifting a bit when tilted, then I'm perfectly happy.
[Xperia Z1 General] danw_oz:
Man reading this thread is horrendous. So much crap talked with a lot of people who really have got no clue what they are talking about.

And the number of people talking about TFT panels not being IPS, do you even know what IPS is? http://www.ronbenmultimedia.com/support/What-is-IPS-panel.htm

Amoled only uses less power with black areas displayed on your screen, because it is not back lit, so if you have a plain black background you are well off.

Best thing mentioned here, move your ass down to a store that stocks the phone and look for yourself, every display unit I have seen in Australia so far looks fantastic.

Guys I am using Xperia Z1. How should I know whether there is any issue in my phones screen. Please help.
[Xperia Z1 General] kannanX10:
with .518 fw my display was really good and after updating to .534 and .257 fw's it is somewhat dull so i decided to flash a .518 fw using flashtool and my display was once again back to normal but there is only chinese .518 FTF is available without playstore for c6902 so by installing filter your screen apk on .518 we can have the default RGB values of .518 fw which can be applied on latest firmwares so some of our display's which became dull after updating will be back to normal
[Xperia Z1 General] Kohozga:
I made an interesting discovery with the screen.

As many of you already know. LCD screens are polarised to some viewing angle. Usually it's 45 degrees like my old DROID RAZR. Reason for that angle is that it's the angle that you normally wouldn't use.

Normally you wouldn't even notice the whole polarisation thing but if you're using polarised sunglasses you would noticed that in some angle usually 45 / 135 degrees the screen would go dim because the the polarisation of phones screen and sunglasses combined would cut out all rays coming to your eyes.

For instance the first generation nexus 7 had a design flaw in screen polarisation angle which was 90 / 270 degrees. That meant that you couldn't use it in landscape with polarised sunglasses.

I was using my new Z1 the other day with polarised sunglasses and noticed that the screen didn't go dim in any angle.

I'm not an expert when it comes to screen but I have always thought that I ordered to get LCD work there has to be some kind of polarisation.
[Xperia Z1 General] dagrim1:
Well, after owning the HTC One and now an LG G2 and Xperia Z1 the Z1 screen indeed is pretty yellowish and dull. All a matter of taste of course, but not really fond of the Z1 screen unfortunately...
