Xperia Z vs Samsung S4, white screen comparison

[roobeyn]

Hi, I was just at the store today and felt that I wanted to compare my screen to the s4 a bit after arguing with my friend about amoled screens, it showed that I was right. I have always been complaining about their bad white balance and inaccurate colors(even without display settings!),
but still xperia Z don't have the best viewing angels but that doesn't matter to me at all, even looking at angels on the amoled it gets reflective and miserable...

Same picture downloaded at both devices (white picture)
Both screens at 100% light

Now judge yourself, no editing done and picture taken with my friends HTC sensation xl

I must say s4 has also very low screenlighting and won't stand a chance this summer in a sunny day

Is the xperia Z a clear winner?

Indeed it is!

Both phones was less yellow but the camera of my friends HTC is oversaturating yellow a bit, but the difference was exactly the same as in the picture

Their true colors are shown in the right middle of the s4 and the left middle of the xz as the autofocus was there

No doubt someone from the samsung camp will go on about how 'deep' the blacks are though

Lol, true blacks, 90% while browsing on the Internet, play store is white and most apps up to 70%, now they have nothing to say about colors I guess

Yeah.. but the deep blacks aren't helping the S4 either! All S4 models (exynos5 or snapdragon version) received by users so far seem to be plagued by yet another AMOLED screen issue, purple/pink smearing is what they're calling it. There is sort of pink/purple smudging if a white/grey image is moved/scrolled over a black background like when scrolling in the settings menu, browsing web with dark bg etc.

Edit: About the whites, of course the XZ screen is better calibrated.

The joys of being an early adopter eh!

Most of my apps, playstore, facebook, whatsapp, dialer, message, contacts and a few more are all black in color. Those apps looks better in black.

Actually it was worse than I though it would be, I expected s4 to be better than s3 and it was even worse?

Hmm, have you turned on the backlight on s4? Looks pretty dark.

S.

S4 screen brightness cannot be on par with LCD's brightness. Even so, your photo makes it look really dark in both phones.
btw, S4 screen's white is much better than S3, I would say the color balance is nearly the same as IPS LCD, very vibrant and punch colors. However, it seems your unit also suffers the red/pink tint in the white.

OK I have to agree that:

1. The Z's white is essentially white whereas the S4...I don't know what to make of it.
2. The Z's LCD is brighter though I have not yet had the chance to properly check the S4 with the backlight on. I will check and update.

So, I was lucky enough to my hands on the S4 LTE version yesterday (my wife was due for an $0 upgrade and she didn't want it as she loves her Note 2, so I jumped at the chance and now I will be comparing both the Z and S4 for a week or 2 before deciding on which one to keep. I'll be posting a separate thread on my findings.

Yes brightness at 100% on both

(assuming that you aren't being sarcastic/facetious)
In an OLED display the individual pixels themselves glow, unlike an LCD display
where the pixels are colour filters with a fixed backlight common to
all pixels shining through to make them light up.
There is as much need/use for a back-light in an OLED display as there is
for a back-light on a light globe/bulb.

So looking on this pictures it seems Galaxy S one has better screen then both appart from low pixely density(grainy picture).
I'm satisfied with screen on Xperia Z but when I look at Galaxy S its hard to go back on X Z screen. It may be oversaturated but if anyone has similiar device to compare screens side by side you will be amazed how this older phone still has excellent screen compared to most new phones (htc one x, htc one, s4, iphone 5,etc).

I compared both, and I think the camera cannot capture it truely, and it's not fair to compared in this way

One thing is with automatic brightness, S4 is much birghter (475 nits compared to a little more than 300 nits of maximum mannual brightness)

The Galaxy S4 uses one innovative approach to overcome this – when Automatic Brightness is turned on, the Peak Brightness becomes significantly brighter in high ambient lighting than is possible with Manual Brightness, up to as high as 475 cd/m2, which is 34 percent higher than is possible with Manual Brightness. This is done so that users can’t permanently set the brightness to very high values, which would run down the battery quickly.

Very reasonable that nobody needs more than 300 nits to read indoor. (actually 200 nits is even more than enough)
It's the same on Note 2, and there is an app name "A Brighter Note" (rooted) that allows maximum manual brightness matches maximum auto brightness.

The OLED theology has not yet surpassed LCD,

and as in your article wrote
"OLED displays are generally not as bright as the brightest LCD displays."
It isn't as bright either

Brightest LCD display on mobile is Nokia 701 (more than 1000 nits), not Xperia Z
And I think you still don't get my point. The pic you showed innitially is the comparison of XZ to 300 nits brightness of S4 which is not the maximum capacity the device can get (475 nits), that's why it looked pretty dim

But the brightness difference between s4 and xz was far beyond 34%, even though it would get the chance to go to it's maximum it wouldn't be higher than xz, if I put my brightness to about 40% they will be at the same level,

Then xz has 60% left to show
and s4 34%

And what I also don't like is the pink color which is supposed to be white

Yes, I know that it will not exceed the brightness on XZ, but you still don't get my point.
I mean the the gap of screen brightness is not as big as your first picture if the S4 showed the highest brightness it can get (which can achieve right after being rooted).
And 300 nits is enough for indoor reading in any case. The use of the more birghtness is for reading outdoor only (or maybe for somebody wanna show off how bright the device is), but brightness is not everything for outdoor visibility. Contrast and reflectiveness is also important.
This one showed that S4 is quite close to HTC One in visibility
