Samsung Unveils 82 Inch LCD

Posted by CmdrTaco on 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."

    1,920 x 1,080 pixels. It could be me, but it does look quite low for a screen that big.

    I wonder how many get tossed to make that one 82-incher....

      There's got to be other factors other than transistors per unit area. These displays are made up of many different layers. Getting 5-10 micron features to line up perfectly from layer to layer over 2 meters can be nontrivial. 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).

      Also - the transistors are still photolithographically defined... which means they have to spin coat a photoresist. The wafers used to make your pentium chips are about a 1ft (.3m) in diameter. These are nearly 7 times larger and are not circular. So... imagine a rectangular piece of glass 2m in one dimension spinning at 3000 revolutions per minute. How does this effect yield? I don't know. But one thing I'm pretty sure about is that larger is not easier.

    its no plasma, so it shouldnt need much more power than your CRT TV.

    But one thing is to be considered: if it is as bright as a small tv, a white picture should be seriously blinding... 2 or 3000 lumen are headlight quality...

  4. What advantages over a DLP projector? by ites · · Score: 3, Interesting

    Why would anyone buy such a piece of equipment in preference over a good DLP projector?

    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.

    And perhaps there are no projectors with built-in TV decoding, which I don't care about personally since I don't have TV, and only watch DVDs.

      Actually, the biggest disadvantage of a front projector is that they are only good in dim to dark rooms. The white screen necessary to reflect the projected light also reflects all the other light in the room. Perhaps if Sony's ChromaVue screen becomes readily available, this will change.
