Screen size, resolution, and brightness are just some puzzle pieces in your total smartphone-viewing happiness

The most common OLED smartphone screens also come with the prefix "Super." Don't let that throw you. Super AMOLED is simply Samsung's proprietary name and approach to making OLED smartphone displays

Pixel density
Pixel density can be a little bit slippery, depending on how you slice your pixels and subpixels. Generally speaking, though, the more pixels you have per inch, the better your picture. Apple's iPhone 4/4S may have a small 3.5-inch screen by today's standards, but its 960x640-pixel resolution still gives it a high pixel density of 326 pixels per inch. Compare that with the HTC One X, which has a 4.7-inch screen, a 1,280x720-pixel resolution, and a pixel density of 312 pixels per inch. Now compare both of those with the Samsung Galaxy Note, with its 5.3-inch screen, 1,280x800-pixel resolution, and 285 pixel density.

Pixel density
While pixel density is an important factor in the smoothness of the overall picture, it's just one facet of many. And when it comes to comparing smartphone pixel density with that of a tablet, you don't necessarily need the same high density.
Former Apple CEO Steve Jobs previously spoke on what Retina Display is during the launch of the iPhone 4. He stated that what makes Retina Display unique is the 326 pixel-per-inch (ppi) resolution into a 3.5-inch screen for the iPhone 4 and iPhone 4S, but the inches have increased to four on the iPhone 5.
The standard human eye will not be able to "discern" the individual pixels at this rate. The eye can see a maximum ppi of 300, according to Apple.

Retina Display is a brand name used by Apple for liquid crystal displays which they claim have a high enough pixel density that the human eye is unable to notice pixelation at a typical viewing distance
