U of CA Constructs 220 Million Pixel Display

Posted by samzenpus on from the wider-than-wide-screen dept.

eldavojohn writes "Engineers at the University of California, San Diego have built a 220 million pixel display across 55 high-resolution tiled screens. Linked via optical fiber to Calit2's building at UC Irvine, the display can deliver real-time rendered graphics simultaneously across 420 million pixels to audiences in Irvine and San Diego."

    University of California at San Diego.

    Can't samezenpus get the least bit of editorial right? Oh, yeah, he can't. He's samzenpus, and he's not an editor, he's an idiotor.

    I mean wtf is U of CA? I've never seen it written like that, ever.

    And to get this rant back on topic:

    Is the screen effervescent?

      THANK you. I made a similar comment a while back, and got hit with a -1, offtopic. I sincerely hope you fare better. U of CA should be written as UC, end of story. It's not offtopic this time though, look at the freaking page title!

    No. "It's exciting," said Joerg Meyer, a professor of computer graphics and visualization who helped develop the screen's software. "This display has higher resolution than the human retina can see." http://www.latimes.com/news/printedition/californi a/la-me-highdef13aug13,1,5603082.story?coll=la-hea dlines-pe-california

    Its tiled displays. This is really more about something along the lines of technology(think video card) capable of outputting ridiculous resolutions.

    The resolution of the human eye is relatively minute (it's usually not measured in MP, but I think the best equivelence was quoted around 15 MP at any given time). The easiest way to explain it, I think, is that your eyes are never in the same position for more than a split second. It's constantly moving and looking at any given object from a multitude of different angles. So no, it isn't able to see 220MP, but at the same time, it is (theoretically) able to see a better image with a higher pixel count, because of the fact that your eye is never stationary.

    But that doesn't take into account your brain. Your eye transfers raw data to your brain similar to a bitmap/RAW file. The way your brain processes this information, though, is more like a vector image. Our brains "see" lines and shapes much more than it sees individual points of colours. Which makes the answer even more complicated. We don't really see all the pixels, but we're able to piece together most of the pixels while our eyes move about, ALTHOUGH our brain "transforms" that information so it makes more sense to us.

    A really neat example that illustrates how the brain processes raw data: close your eyes, and get a friend (or yourself, if you can trust yourself not to cheat) to hold up something that is near the outer edge of your peripheral vision. Open your eyes, but don't move them - keep looking straight ahead so that the object is still near the edge of your peripheral vision. You can SEE the object, and can possibly even tell what it is. But what colour is the object? Even though your eyes are able to see colour even in your peripheral vision, the brain doesn't think that the information of colour is as important as the outline/shape of the object. It is only when something is near the centre of your vision (in other words, where your attention usually is) that you can tell what colour it is.

    1. Re:No, but yes by wumpus188 · · Score: 5, Informative

      No. You cannot see the color of the peripheral object because the cone cells, which are responsible for the color vision, become sparse towards the edge of the retina.

      It's not usually measured in pixel count because pixel count is an entirely irrelevant concept to eye resolution. The angular resolution of the eye is extremely high at the center of the image, and falls off extremely rapidly in a very steep bell curve. So unlike a monitor, the number of pixels across the eye's vision does not correlate at all to the maximum angular resolution of the eye.

    I mean, it's not a single display: it's a hundred LCDs stitched together.
    When they create a 220 million LCD screen, then great.
