Shame to Sony, same old Sony being cheap and using about 4 panels for display:
JDI type 1 - AH-IPS (this was used for the ZU)
JDI type 2 - VA (Xperia Z/ZL leftovers)
Sharp - VA (Xperia Z/ZL leftovers)
Samsung - S-PLS (Will only be used after all the VA panels are used up)

Sony is using up the remaining inventory from Z/ZL and mixing in some AH-IPS panels. Once all the VA panels are used up Sony will only use AH-IPS and S-PLS panels.
This would explain why some prototypes and production units have outstanding displays and some are just like Z/ZL.

That's proof:
1) According to gsm-arena
Contrast 1513:1
Brightness 580 cd/mē
Black level 0.38 cd/mē
This is an IPS panel like on Xperia ZU.
Verdict: Much better screen quality.
2)According to hi-tech.mail.ru
Contrast 620:1
Brightness 488 cd/mē
Verdict: same poor panel as on Xperia Z.
3) According to ixbt.com
Contrast 600:1
Brightness 460 cd/mē
Verdict: poor screen.
Pixel arrangement 100% same as on Xperia Z.

And pixel arrangement on ZU (IPS) for compare:


4) Thanks babylonbwoy for link - French site Les Numeriques tested the Z1 (lab test), they says that the panel is MVA Technology (according to them viewing angle will always be worst than IPS just du to this), and their test shows

Contrast 660:1
Brightness 500 cd/mē
DeltaE 5.5
Remance 13ms
Latence 109ms

XZ1 test http://www.lesnumeriques.com/telepho...6826/test.html
XZ test http://www.lesnumeriques.com/telepho...5135/test.html

So, don't buy first party or go to local store and try screen on hands.

So, any way to tell aside from subjective viewing? Being new to Xperia I haven't seen the other screens.

The one who started spreading that the Z1 uses the leftovers panels from the Z and ZL is total bull****.
I can confirm no such thing occurred.
Practically, if you think about it, how Triluminos works is by emitting a blue LED light into this quantum dots of reds and greens.
Conventional LCD screens like the one that canes with the Z have its white LED shine past the RGB panel.
So if that donkey "source" is correct, Sony have to tear open the leftovers, modify the existing panel for it to be compatible for the blue LED.
It's simply not practical, or perhaps, pure stupidity.
