A Closer Look: Comparing Apple's iPhone 4S and Samsung's Galaxy Nexus
By Michael J. Miller (PC Mag)


Galaxy Nexus, with its 4.65-inch display, is a lot larger than the iPhone 4S, which has a 3.5-inch display. The Nexus measures 5.3-by-2.7-by-0.4 inches, while the iPhone measures 4.5-by-2.31-by-.37 inches...
The Nexus display is not only physically bigger, but it also offers higher 1280-by-720-pixel resolution, compared with the iPhone's 960-by-480...
Nexus display uses Samsung's "Super AMOLED" organic LED display, but uses Samsung's PenTile technology (which has two subpixels per dot, not three)...
In practice, though, the iPhone looks quite good and is typically brighter.

Screen technology is getting complicated... comparing apples and oranges...
PenTile

matrix family refers to a family of patented subpixel matrix schemes used in electronic device displays. PenTile is a trademark of Samsung.
