FlatpanelsHD on the Galaxy Nexus OLED display:
The OLED screen measures 4.65-inches and uses a 1280×720 HD resolution. The screen size is probably too large for the typical consumer but it delivers a lot of pixels – at least on paper. It has 315 ppi (pixels per inch), which is slightly lower than the Apple iPhone 4 and iPhone 4S, which has a pixel density of 326 ppi. One would imagine that this qualifies as a “Retina Display” (because it is over 300 ppi) but actually it does not.

And if you calculate the real pixel density you will find that the Galaxy Nexus is actually closer to a “real†ppi value of 200, which is slightly lower than on the Galaxy S II (that uses a Super AMOLED Plus with RGB pixel structure). Some claim that a PenTile panel needs around 420 ppi to qualify as a Retina display and that is probably also the reason why Retina is nowhere to be found on the specs sheets of neither Galaxy Note nor Galaxy Nexus. If you are keen on a Samsung smartphone you might even find that the screen in the Galaxy S II is better. But the iPhone 4 and iPhone 4S still lead the pixel race. Some people say they never notice the PenTile pixel structure but it is just like a stain on a carpet; once you see it, it is hard to disregard.
Yikes, they are going with a PenTile panel for the Galaxy Nexus?
