I really don't get all this nonsense about OLED being better than IPS... I have a Galaxy Note 2 (non-pentile) and the screen IS GORGEOUS. The blacks are like the screen is turned of! My iPad 4 has a little washed-out blacks and I don't understand why all these technical specifications are so important to people like you, because what really matters is what you SEE and perceive. And OLED looks much better than IPS.
Also, I don't don't see Galaxy Note 2 users, for instance, asking Samsung for better battery life, or this or that... But when I come here, all I see is "Apple, please do this... Apple, please, do that"... Asking for things we already have in the Android side for years!
I'm not saying it's a bad screen, just that it isn't as good as the iPhone 5's IPS screen. Of course, this is all like the LCD vs Plasma debate again and it ultimately depends on the viewer's perception and what you value in a display.
It's generally accepted that most IPS panels will have:
-Better brightness
-Better contrast (with ambient light)
-Whiter whites
-More accurate colors (99%+ sRGB coverage)
While the OLED screen will have deeper blacks.
Of course, you could personally value deep blacks more than the 4 other things combined, it all depends on your perception and how you use your phone.
Some people may practically never use their phone in the dark and not really notice blacks aren't perfectly black on an IPS screen and somebody else could not value color accuracy at all because he never checks pictures/movies on his phone so OLED wouldn't be a problem for him.
Also, just like when shopping for audio, somebody could look for a perfectly balanced, accurate flat response while somebody else could be looking for a colored, unbalanced, bass-heavy sound because that's what he thinks sounds good. Likewise, some people like OLED screens because colors "pop" even though they are technically inaccurate.
Technical specifications alone are not important for me. I do notice differences in color accuracy and white level on IPS and OLED screens. I compared my iPhone 5 to my friend's GS3 in bright light and the difference was night and day. I use my phone almost exclusively in bright light.
The Note II was said to have slightly better colors and a RGB matrix. I have yet to see one to compare myself but reviews aren't too glorious. Turns out it still have the same
overvibrant colors as the GS3, the same low brightness and it still uses some sort of weird PenTile-like matrix that isn't traditional PenTile:
The day they will offer OLED displays with a real RGB matrix, with excellent color accuracy (close to sRGB), bright whites that don't have a green/purple tint, and excellent contrast in bright light
while still beating IPS in black level, we could call OLED the winner. As it is however, the tradeoff simply isn't worth it.
