Samsung Unveils New 10" Retina Display 155

Posted by timothy from the one-day-by-and-by dept.
adeelarshad82 writes "Samsung has unveiled a brand new 10.1-inch display that supports a maximum of 2560×1600 pixel resolution that could be ripe for next generation tablets. Samsung's new display is more of a tech demo than anything else at this stage. While it looks impressive, it's not quite ready for broad production. It does, however, prove that high pixel density and high-resolution tablet displays are possible without unreasonable power requirements coming along in the process."

    It does, however, prove that high pixel density and high-resolution tablet displays are possible without unreasonable power requirements coming along in the process.

    I'm not sure the power requirements are the biggest issue with this type of display. I think cost is going to be the biggest hurdle it has to clear before it finds its way into a tablet.

    • Agreed. You can get 2560 monitors today; however, they all seem to be professional displays and typically are 27" and higher. Thus they cost 3-4X than a cheaper consumer grade monitor. The only consumer model I know that is being sold is the iMac 27".
    • Kind of makes me sad that HD is only 1080p. I just saw a 70 inch TV go on sale at my local electronics superstore. 1080p at that size isn't such good resolution. Especially compared to the 10 inch retina display that is 1600 vertical lines. I would like to see the result of this technology 10 years. Will everybody be buying 4K resolution TVs? Will we have cables with enough bandwidth to carry the signal? What medium will we get the video on?
      • It's true 1080p isn't mind blowing at that size, but try watching a 70" TV in standard def. At least with HD, you can get an acceptable image on a larger screen these days.

      I for one welcome our $300 16,000x9,000 pixel 24" monitor overlords. We've been stuck at 1920x1080 for too long. In terms of cheap displays, anyways.

  • I'd like the 24-inch version of this, please.

    • I'd rather have the 27" or 30" version to replace my current main 27" IPS monitor running at 2560x1440. Or maybe replace my secondary 22" monitor and make the old 27" the "crappy" older monitor. The PPI difference might make it a bit weird though.

        A 30" version with the same total resolution as 24" at 200dpi would be far more useful anyway. 150dpi is a lot at desktop viewing distances.

        • Yes, a 27" monitor at 2560x1440 has a pixel density of 109 PPI and at normal viewing distances you just don't see individual pixels. Well, you can see the pixels but it's not like they stand out like a sore thumb as they do when you start to look at pixel densities closer to 80-90 PPI. 150 PPI would be extremely nice, no risk of small text being limited by the pixel grid anymore...

Monitor prices continue to fall but decent resolution monitors aren't because no one is buying them. All the factories are spitting out HDTV.

        I found one T221 on ebay. It was 1700$.

        • I agree. Over 10 years ago I was running 2048x1536 on a high quality CRT, and that cost only $300.

          The T221s were cheaper before, but they've become more sought out and so the prices have been flying back up. But hey, they did debut for $18,000, and then dropped down to about $8,000, so that's still a steal! :-P

          The CRT industry, for keeping people at mid res for so long that we got coiled like a spring waiting for larger sizes... by the time LCD's became cheap enough, it wasn't wether you were ditching that your old screen to get a new 1280x1024 res, but wether you were trading 14-inch CRT for "lots of inches more

            PROTIP: A 1920x1080 pixel monitor can display two 960x1080 pixel windows side by side. Window managers have "Tile Vertically" and "Snap" features to take advantage of this.

      The problem with 200 dpi on a desktop monitor is viewing distance and the fact that UI's don't scale as we would like them to. T221's can be bought on eBay and there's a Yahoo newgroup that discusses how to use them. Apple even provided support in OS X once upon a time, but that's fallen into useless disrepair. Try one, but you probably won't like it.

    • It is getting there, but as of yet there are still hurdles to be dealt with.

      The biggest is just cost. Pixels cost money, every sub pixel needs a transistor (or two if you want a nice high quality IPS panel) and so more pixels equals more cost. You might think you want a display like that, but are you willing to bear the cost? Such a monitor could easily cost $3000-4000. Still interested?

      Another big one is UI scaling. Programs and OSes are only now getting on board with the whole resolution independence thin

        There are so many applications for Windows that there's usually an alternate application for every need, at least one of which will hopefully support the system DPI setting that has been in, for example, Windows for the past decade. Well-known applications are probably used by at least one government, and that government can invoke accessibility law (Section 508 [wikipedia.org] and foreign counterparts) against applications that do not support system DP

        So it is stupid, inept, proprietary software which is holding the world back. And the HD craze. To be honest, it is more the HD craze than anything, and I am glad the geeks are starting the rebel. I was dissed as a whiner when pointing out last year that reasonably high resolution monitors were disappearing, because of the gullibility of the public.

      • It's called Dual Link and you simply have to select cards with that capability or with SLI/CrossFire to handle that density. My current card is a budget card >$100 when new (Radeon 5670 w/512m) that supposrts both Dual Link and CrossFire. This means I could easily handle a 5120x4800 display using a pair of them for >$250, which is cheaper then a single High End Card (not top line).

    Unfortunately, it's one of those nasty 'Pentile' displays, where subpixels are treated as pixels to inflate the on-paper resolution. If you treat them as actual useful displays where each pixel contains all the sub-pixels required to display the full range of colours (3 for regular displays, 4 for pentile, despite the name implying 5), then the actual resolution is lower than a traditional pixel layout.

    • I've no objection to pentile displays in principle. Humans do have higher green perception and so perhaps such a display can be useful. For that matter it is similar in principle to the Bayer pattern that still digital cameras use for their sensors.

      The problem I have is like you've noted with overselling it. You can't claim more resolution on less subpixels. The net result will be a more grainy image. Cameras like to do this too, their "megapixel" count is the total acquisition area, ignoring that each pixe

      • But like with cameras maybe the marketing just gets pointless. Sure a 10megapixel camera doesn't have 10million full colour pixels but due to the interpolation of a beyer pattern being actually quite good the end result actually appears quite sharp when viewed 1:1 on a computer display, so really no one gives a damn that they have only 5 million green, and 2.5million red and blue pixels.

        In practical terms the difference between screens is minimal even if the resolution numbers are artificially inflated. The

So when you compare pictures from a camera like a Sigma D10 with for example a D7000 12megapixel camera you still end up with the same result. After all Beyer interpolation can be ignored and instead the local 4 group of pixels can be combined. This is used quite extensively in astrophotography. The end result not only has no interpolation Foveon style, but also looks better as the Foveon sensors currently are be

      You can have a fully bendable display once we figure out how to combat the creasing problem. Hint: Paper currency is "wrappable" -- Take a few from your wallet and look at a "straightened" piece of fully bendable currency and you'll get my point.

I'm sure they tell focus groups that this is what they care about. And there are monitors out there [newegg.com] that go to 2560x1600, but they are marketed at "professionals" and are absurdly expensive. What's worse, they seem to be immune to whatever force that's rapidly driving down the prices of the 1080p monitors. Some manuf

      Of course, it took over 10 years for HD to make it from being developed until it was a common consumer product, so don't hold your breath. (NHK developed 1080i around about 1980, first commercial broadcasts in Japan 1994, first in USA 1998).

      Android device manufacturers and RIM will certainly buy some of these, in the same way they buy panels from Samsung already. The issue though is one of cost. Unless you can buy in the volumes that Apple do, and can afford multiple-billion dollar prepayments like Apple do, then you pay a higher price for those panels. Your options are then to sell your product at a higher price to consumers, or sell it at
