Going Into the Pixel: Retina Display Under a Microscope

If we take a few (or an order of magnitude) more steps closer to the display and put it under the microscope we can get an even better appreciation for exactly what Samsung (and Apple's other display vendors) have done with the creation of this panel. Below are shots at 50x magnification of the display from the iPad 2, new iPad, ASUS TF Prime and iPhone 4S, organized from lowest to highest DPI:


Apple iPad 2, 1024 x 768, 9.7-inches


ASUS Eee Pad Transformer Prime, 1280 x 800, 10.1-inches


Apple iPad Retina Display (2012), 2048 x 1536, 9.7-inches


Apple iPhone 4S, 960 x 640, 3.5-inches

What you're looking at here are shots of the three subpixels for each pixel. Subpixel shapes will vary by panel type/manufacturer (hence the iPhone 4S vs. iPad subpixel structure), but the increase in density is tremendous.

    I mean to say "it helps to have a faster CPU". Reply

    You notice how you tend to justify everything on hardware specs? It may have a slower CPU, yet performance and actual usage is well those devices with faster chips. If having a faster CPU is so important, then why hasn't Apple used them? That would be an easy fix right? Why would Apple want to handicap itself by using such low specs? The answer is because it doesn't need to. Clock speeds are clock speeds and the only thing that matters is the user experience. In my experience, Apple devices by far have the best experience and stability. So what ever numbers listed in tech specifications, are just that. May look great on paper. Reply

    Are you saying that for example, web sites don't load faster with a faster CPU? With a slow CPU, it's impossible for web pages to load fast no matter how good the OS is. Reply

    "Are you saying that for example, web sites don't load faster with a faster CPU?"

    Are you saying that you can compare the user experienced speed of the devices with different OSs / apps by comparing the (paper) CPU specs?

    Sorry, how stupid is that?!

    Those tech specs / cheapest parts prices fetishists are really funny. Unable to learn from a long history of 'paper spec marketing', they think they are cleverer than the rest of the world but are in fact easier to influence than people who are able to choose by defining their needs and comparing those needs to real world experience with a set of given devices.

    Ever notice that I'm correcting you all the time, and that the corrections happen to be pro-Apple because you're ridiculous Android bias leads you to make ridiculous claims?

    Both CPU and GPU matter. Overall, taking into account both, the iPad has better performance. This is backed up by all the impartial reviews which note how smooth and fast it feels, in comparison to Android tablets. It also has by far the highest resolution and largest App store.

    ICS is already smooth because it supports hardware acceleration, which Android didn't used to have. Most of the reviews are based on Honeycomb. "iOS is smooth blah blah blah" - that's just because iOS has hardware acceleration, just like WP7, which people also say that it is very smooth. Reply

    The same ICS which the Galaxy Tab doesn't support yet? Reply

    Hm. So you need to buy several different tablets to compete with an iPad? LOL. Sounds 'overpriced' to me

    (Those points are stupid: you will always find one other product that has a better implementation of feature X (price, size, smell, you name it), while laking in other areas. But at the end, you want ONE device. So such comparisons are moot.)

    Why not go deeper? Samsung also buys components from various manufacturers, and puts it together. They don't make the backlight, the frame, the glass cover. You can go so deep to end up with only mining companies on your list, because everything we use comes from the earth (be it metals, oil (for plastic), and so on). Whatever the case, samsung didn't put the product to market, Apple did. Samsung's just going to see what Apple is successful at and copy it. Just like everybody else. Reply

    Which of the mentioned stuff is high tech, that you can't get from other suppliers. pretty please? Are you seriously comparing screens and glass covers? Reply
