Samsung Unveils 82 Inch LCD 232

Posted by CmdrTaco from the all-the-better-to-doom-you-with dept.
karvind writes "Physorg is reporting that Samsung Electronics has developed the world's largest liquid crystal display panel. This 82-inch TFT-LCD is 17 inches larger than LCD flat panel previously developed by Sharp. This development challenges plasma display panels in this market area. This full HD image quality (1,920 x 1,080 pixels) TFT-LCD panel was developed at the company's new production complex in Tangjeong, Korea. The soon-to-be operational 7th-generation production facility uses glass substrates that measure 1.87m x 2.20m."

      That was once my gripe against big screen TV in general. But combine the higher Res of HDTV, and the fact that you dont sit 12 inches from the screen, and it should be fine.

      1920x1080 is the MPEG HDTV standard. The TV does exactly what it should do.

      Now granted, if you wanted to use it as a computer monitor, it would be different, but 99% of folks are going to use this as a TV, so that resolution is right on.

          Your beef?! Do go buy yourself a 40-60" one, along with that small car. This particular model is for those who already have a fleet of small (and large) cars, and need a large central TV to frame with all the other 40-60" ones they already have. IOW, you're NOT the target market for this model, so don't take it personally that it doesn't come bundled with a small car.
        • Why not give the expensive 60" screen a miss, and get a hig res computer monitor and sit closer still? I mean $600 will get you a pro tube that can handle 2048x1536 with better colour than and LCD or Plasma.

          Well the thing is, maybe you want a room where more people can watch, and still have a bigger screen experience. A 20" monitor is plenty when you are 2' away from it, as with computers, but it's kinda hard to have friends over and watch on that, gets crowded.

Also, I've heard that the glass sheets used to make the active matrix of transistors can begin to behave like paper when they get that large (i.e. they can bend quite easily).

      There are problems with plasma displays that make me veer towards LCD.

      1. Plasmas suck up power like there's no tomorrow. I hear 300-500 watts is nominal. That 102" would definitely be on the high end of the scale.
      2. Plasma burn in.
      3. Limited lifetime.

      Until these disadvantages are taken care of, I will pass. LCDs have none of these problems and with the new 7G Samsung, it looks like they may have taken care of the viewing angle and brightness problems.
      • Interestingly enough, two of those three make me want to go for DLP or DLA over LCD as well (I'd never get a Plasma, just putting it out there). LCD burn in is possible and does happen. LCD pixels weaken over time and die or get turned permanently on. LCD and Plasma both still have problems, which is why I will be going with rear projection at some point.

        • Due to the increased resolution, the ideal seating distance from an HD display is roughly half that of traditional SD 'big screens.'

            Ideal distance (for human comfort as tested by the japanese in the 60/70s) for SD is 4 times the height.
            Equivalent distance for US-HD when compared to that of US-SD is 3 times the height.

            I base the 4 times the height on human comfort rather than equivalent viewing quality of SD vs HD.

      Without pulling up the actual specs...
      2.2m = 220cm
      220cm / 1920pixels = 0.114583cm/pixel
      Or, in other terms, about 1.15mm/pixel

      1.86m = 187cm
      187 / 1080pixels = 0.173148cm/pixel
      Or, in other terms, about 1.73mm/pixel

      Slightly non-square, I'd imagine if I'd pull up the actual specs of the display panel itself (not the entire casing) I'd get square, and smaller, pixels yet.
      • The 2.20m by 1.87m measure is of the glass substrate they use in production. This is enough for a 110" screen, but for whatever reason they cut it down to 82" for this one.

        So the pixels are probably around a square millimeter each, not too bad.
        • Oops, silly me, the "whatever reason" is of course that they cut two screens out of each substrate. This puts the measurements at 1.87m by 1.10m, and each pixel would be pretty much exactly a millimeter to a side.

          The largest 16:9 screen they could get from this substrate, incidentally, would be 97" (source [hankooki.com]). Obviously by cutting in the other direction and wasting quite a bit of the material, though.
    • The substrate is that big (2.2 x 1.87 meters), but that's for two 82" screens. A single screen is a little less than half that size -- it fits 1920 pixels into something less than 1.87 meters, and 1080 in less than 1.1 meters. If they're square, then they're slightly less than 1 millimeter on a side.
    • The substrate is much bigger than the screen.

      The screen is 82" on the diagonal =~ 2.08m
      The aspect ratio is 16:9 so
      (16x)^2 + (9x)^2 =~ 2.08^2
      337x^2 =~ 4.34
      x =~ 0.113m

      So it measures about 1.815m x 1.02m. I imagine it has more than 1920x1080 pixels and has image enhancing to scale the image up, but if it were 1920x1080 then the pixels would be 0.094cm square which is about 1/25th of an inch.
    • From the article:
      Full HD 1,920 x 1,080 pixels 16:9 aspect ratio
      Resolution 1,920 x RGB x 1,080 (Full HD)

      Which makes the pixels 1mm square. Or, 0.04 inches square.

    A projector is light and can be easily moved. It gives you a huge display, with comparable resolution and brightness. It is cheaper. It can double up for business use, and can be carried in one hand. And when it's switched off, you get your living room back.

    The only disadvantage of a projector is that it can be a little noisy - DLP chips get very hot and need a lot of cooling.

    From TFA:

    Pixels: 6.22 million (number of RGB sub-pixels)

    Yes, that's 1920 x 1080 x 3 = 6220800. I can't wait until the camera manufacturers catch onto this new method to inflate the number of "megapixels" in their cameras. Fifteen megapixels here we come!

    (Just don't mention the bayer pattern [howstuffworks.com] used on CCD's)

    • Alot of small TFT displays (such as those for use in automobiles) already do this. They claim for example 2400x480 resolution, but when you get the thing you realize they are counting "sub-pixels" and you really only have an 800x480 display.
    • They give the rating of the CCD, not the effective number of colour points you get. For example my SD (720x480) DV cam has over a megapixel CCD. Do the math you find out that it only takes around 350,000 pixels to do SD. The reason it has a larger CCD is because of the mask on it. If you go a setp up, to real pro gear, you discover the numbers drop back down to below a MP, since they split the light with prisms and go to 3 seperate CCDs.

    Just imagine the size of the keyboard on that laptop. You could play hop scotch on the numeric keypad.
  • The Apple Cinema Display HD actually has a higher resolution than this...
  • ... and only 2,073,600 are either stuck or burnt out.
