After the Galaxy S III announcement many people, including
us, were wondering why Samsung decided to use a PenTile Super AMOLED screen
instead of an Super AMOLED Plus unit.
Well, a Samsung spokesman has explained why. The reason
turned out to be plain simple – it’s not because Samsung can’t satisfy the
demand – it’s just that the PenTile will last longer.
As it turns out, the RGB AMOLEDs degrade much faster than
the PenTile AMOLEDs so the picture quality becomes worse faster. The blue
pixels are the ones to blame – they degrade faster than the red and green
pixels. The PenTile displays have less blue pixels because of the RGBG subpixel
layout and that’s why they have longer life span.
