Another video.  Not in english though

Take a look at this picture, it shows the displays of SIII and One X under a microscope:


You'll notice the following:
1.  SIII's Pentile display has a RGBG pixel arrangement (Red-Green-Blue-Green)
2.  One X's display has a RGB pixel arrangement (Red-Green-Blue)

On the Pentile screen, each green sub-pixel shares a red and blue sub-pixel with another green sub-pixel.
This makes it having lower pixel density compared to the SLCD2 in One X.

Regarding the brightness, since LCDs do not produce light themselves, they require a backlight.
Amoleds on the other hand require no backlight as each pixel produces its own light.
LCDs have backlight on even when displaying black colour but the pixel in Amoleds just switches off, hence the deep black.  This results in higher brightness/nits in LCDs displays.

I could be wrong here, correct me in case there're mistakes, especially on the brightness which I'm not so sure


She's so lucky
Yeah, looks like the energy-efficient Exynos and extra battery capacity really play a big part here.  Especially during video playback
