We, as a screen consuming culture, thanks to Retina display, have come to recognize jaggies: those little jagged edges that the human eye can perceive on fonts and pictures where the individual pixels are visible, even if only just slightly, or if you have your nose to the screen. And the real kicker is that once you start seeing pixels and jaggies, you can stop. I’m seeing them now, typing.
To illustrate the pixel difference though, presents a bit of a problem. Most of us still use screens that aren’t Retina Display, so showing you a picture from a Retina screen versus one from a standard screen will give you the same results. Jaggies. So how can we illustrate and test the actual difference that you will see? We zoom in as close as we can go. In fact we’ve zoomed in to the actual pixels of each of the iPad screens to give you an idea of what you’ll be looking at.
Under our 150 times zoom microscope, you’ll see each block of Red, Blue, and Green (a square of RGB, 3 blocks). Each of these three block are equal to one pixel. The difference in displays is due in part to how many of each of these tiny blocks Apple can squeeze into one inch, or pixels per inch (ppi). (The other part are some very tricky and clever innovations on Apple’s part of how the screen actually functions.) We’ve compared the Retina Display with each of the previous iterations of the iPad along with the new mini in order to give you an idea of what the difference between them is.
