While many users have agreed that the S3’s screen is a natural evolution from the S2’s panel, there have been more than a fistful of critics disagreeing with that opinion(Pentile vs RGB), which has led to Samsung officials issuing statements defending the new display.
Naturally, that hasn’t completely calmed the criticism “storm”, but maybe DisplayMate’s most recent in-depth analysis will manage to do just that. According to what looks like a very objective report and comparison based simply on raw numbers, as well as extensive lab tests and measurements, the S3’s display is indeed an evolution from the S2’s panel, which itself is much better than the original Galaxy S screen in most areas.

OLED, PenTile AMOLED, Super AMOLED, Super AMOLED Plus, and HD Super AMOLED
The marketing terminology and puffery for displays varies among manufacturers and is confusing… The Google Nexus One was listed as having an “AMOLED” display.
The AM stands for Active Matrix, but that prefix is unnecessary because all current LCD and OLED Smartphones, Tablets, Laptops, and HDTVs use an Active Matrix. All subsequent generations of Samsung OLEDs are called “Super AMOLED” in the same way that you’ll often see “Super LCD” advertised as well. Not all manufacturers use the “Super” terminology so it’s best just to ignore it as advertising puffery.
“HD AMOLED” means that the pixel resolution of the display is High Definition 1280 x 720 pixels or higher. But here is where it gets complicated and confusing – if you see “Plus” that means that the display has the traditional 3 Red, Green and Blue sub-pixel arrangement that is found in almost all display technologies.
If you don’t see “Plus” on Samsung devices that means that the display has only 2 sub-pixels per pixel (a Minus) – half of the pixels have Green and Red sub-pixels and the other half have Green and Blue sub-pixels, so Red and Blue are always shared by two adjacent pixels.
This technology is called “PenTile.” PenTile screens have only half the total number of Red and Blue sub-pixels as the traditional 3 sub-pixel displays, so they aren’t as sharp as traditional displays with the same pixel resolution and their highly advertised screen PPIs are not comparable. This is especially noticeable with colored text and graphics.
PenTile uses Sub-pixel Rendering and Anti-Aliasing that partially compensates for this shortfall. PenTile displays have some advantages: they are easier to manufacture and therefore cost less, and for OLEDs the Red, Green and Blue sub-pixels are sized differently and that improves Blue aging somewhat (see below).
For now, OLED displays over 250 PPI use PenTile technology. It’s expected that the next generation of OLEDs will be called “HD Super AMOLED Plus” and they will have the standard 3 sub-pixels per pixel.

But as for could the S3 display had been better had they used RGB ? Definitely, but the question is how much an impact would that be on the battery life and longevity of the screen.
Some fans say the sacrifice is well worth the benefit, whereas those against say otherwise. So until somebody does a review comparing the 2 on that point, we won't know for sure
