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.

    So any word on rest of the benchmarks ?

    Thanks for the quick write up on the display. The resolution is out of this world! I current have a 24inch Dell monitor 1920x1200 for my workstation that you reviewed a few years ago. Amazing, the Ipad3 blows it away with a better resolution at smaller than 1/3 the size and still has 10 hour battery life!

    I am now contemplating my first tablet purchase, just because of this screen. I've never in my life bought an Apple product yet, but this might make me do it. I currently have the HTC Rezound, which has one of the best resolutions for a smart phone, and blows away my original droid in most all areas other than screen hardness, it scratches way to easy.

    At my 46 year old age, the 4.3 inch screen just isn't good for watching movies or reading a book, and as much as I like the sound of the fire, the better the text is on the screen, the easier it will be for reading.

    Some people think Apple didn't go far enough, but for me the screen eclipses everything in the world, and does it portable!

    Thanks again!

    I don't know why it wasn't included as a comparison, but there will be a 1920x1200 Asus Transformer out shortly. The DPI won't be quite as high as the iPad, but it will be fairly close.

    How would AnandTech review unavailable products? There's ALWAYS something newer/faster/better coming next year.

    Except that sometimes, any specific item does not. I suppose Asus is in the game for some time to come, but it sure seems like < 10% of the tablets announced in early 2011 ever made it close to retail.

    Only then will the issue shift to the overall usability/attractiveness of the total OS/hardware/retail/service/app experience. The Transformer line has gotten some attention for having an excellent display, but now that the display will be “almost as good,” the other factors will come into sharper relief.

    Actually you could have compared it with previous 7-inch hardware, a Samsung Galaxy Tab 7.7 Plus with 1280x800 is 196 DPI. A Huawei MediaPad 7" 1280x800 is about 215 DPI. If comparing it with other sized screens where that relevant here. Of course we have had 15.0" 2048x1536 screens on laptops too there is also high res 22" screens for medical use with 3840x2400, that's 204 DPI on a desktop. That is actually retina based on Apples calculation of screen distance if you like to call it that. I don't think you need to hit that sweet spot though. High-dpi is nice but there is more to consider in most cases. So of course it's more to look at in the world of high-res screens.

    I have an LG spectrum, one of the few 720p 4.5" phones sporting a PPI of something like 326.

    You should be aware that iOS doesn't have text reflow in the browser. A couple browsers allow you to increase font size, but that only works on simple web sites. Often times it completely breaks the layout and/or causes lines to overlap.

    So if you're planning on doing a lot of web browsing with less than perfect website, the iPad might not be the device for you.

    The Screen is a Godsend. I always hated looking at poor saturated photos I took, which looked beautiful on my Dell u2410
    Now they look good on both :)

    Now if we could get Apple to make a 4k monitor :)

    or Dell :)

    Neither of the two is going to make a 4k monitor before those who work the real magic (the panel makers) are ready for it at a reasonably production price.

    Besides, you'll likely see it first from the highest end of the spectrum, like Eizo or NEC, not apple or dell.

    IBM released a 4K monitor over a decade ago.
