According to this site, it has the same screen as the Galaxy S4:
Nokia Lumia Icon
It's a Super AMOLED screen with PenTile matrix:
Super AMOLED
Pentile:
"PenTile relies on the human eye design -
if you reduce the number of blue subpixels, you do not reduce the image quality. But even Samsung admits that a real-stripe RGB matrix is better than Pentile, for example here's some marketing image from Samsung showing how a non-Pentile display (the Super AMOLED Plus) is better than the pentile Super AMOLED. Some people indeed do not like PenTile displays. Mostly it seems because there is a visible pattern when you look at the display up close. Your eyes get used to this pattern quickly though, and
the higher resolution the display is, the less visible the pattern is."
Note that Super AMOLED Plus screens are a lower resolution, so you'd be trading a higher resolution for RGB matrix. Also, PenTile displays last longer.
