The Droid Incredible and the Samsung Moment are both AMOLED.
The Galaxy-class phones alone are SAMOLED.
I'm not confusing brightness with vibrant.
Brightness is a standard video term.
Vibrant is a subjective/descriptive term.
The colors on the S/AM/OLED screens have a higher saturation - another video term.
The Droid Incredible is like the EVO - 480x800 - but unlike the EVO, its smaller size (3.7" vs 4.3") means that if anything the dot pitch will be finer - unimportant as dot pitch is invisible at the normal use case of about 9" ~ 15" away.
Two displays, running the same user GUI, at the same device resolution, cannot have a difference in "blockiness" of the pixels.
Pixels are pixels. They can only have light associated with them. The hue of SAMOLED pixels are different than for LCD - that's it, the truth, the whole truth and nothing but the truth.
And as I write this, I'm holding a Samsung Moment next to an EVO - and the Moment has no blockiness whatsoever - it's pleasantly razor sharp. And its font renditions are superb.
Oh - besides hue - the light from the EVO's LCD display appears obviously circularly polarized, whereas the Moment is linear - but both are sporting anti-scratch covers, so take that with a grain of salt.
So - it's still you.
And by the way on that whole saturation/vibrant thing -
Colorfulness - Wikipedia, the free encyclopedia
As I've said elsewhere - hold both up to a calibrated HDTV display - neither is going to come out favorably with respect to color.
So, the preference in the end will be subjective.
At first, I missed the vivid colors of the Moment - but quickly got used to the EVO as being more natural in some respects (not the purplish tint it has, though!!).
We don't need any more resolution (it's last of the four factors to affect perceived detail anyway, despite the fact that I'm committing forum heresy) - what I would dearly like to have in a future SAMOLED is a set of freaking color adjustments.
They'll give me that when I get my sharks with frigging laser beams on their heads.
