    Both have many advantages and disadvantages, suggest you do some
    research online as well as compare models of both types in the store.
    It's too broad of a subject to give you a simple answer.

    Obvious difference:plasmascreens do burn in easely.

    Unless you have a real need for a flat screen hanging on your wall, I'd
    stick with CRT for as long as they are around. Many of the problems on both
    LCDs and plasmas are not supported to component level by the manufacturers.
    Replacing boards is fine as long as the unit is under warranty, but an
    expensive exercise, when it's not.

    If you really want one, go to the store and ask to see a sports programme
    where there's plenty of movement. Plasmas are reknowned for generating
    movement artifacts, which can be quite annoying to watch. Don't make the
    mistake, though, of looking at a 54 inch plasma screen from 2 feet away.
    You'll see all sorts of nasties that wouldn't be apparent at a normal
    viewing distance.

    Some of the Sony stores have good displays of both with proper lighting and
    seating. Worth a look to get a better idea of the two, and how they stack up
    with respect to each other, and CRT sets.

    Depends again on specifically what size of set you are looking at
    purchasing. There are LCD Projection sets and LCD Televisions. As noted,
    plasma sets have a problem with burn-in which in greatly minimized in the
    LCD and DLP technologies The LCD and DLP Projection sets use lamps that can
    be an issue. Get some more information, go to the local retailers and look
    at the features within your spending limits, then buy what you want. Suggest
    the extended service agreement.
  6. It depends on the application, size, and budget.

    LCD generally is better for use with computers, where smaller screen sizes
    are used, where off axis viewing is limited, and where brightness is needed.
    PDPs are generally better for video, have better blacks, and are more cost
    effective in larger screen sizes. PDPs have phosphors that age, though
    newer sets have much improved this area.

    These are generalizations. Each factor will vary among brands and models as
    well. The best of one technology may outperform poorer designs in the other
    type in any area. Prices in both vary greatly. View each set under the
    conditions you will be using it and judge actual performance rather than
    looking just at the specs, which may be very misleading.

    My biggest gripe about LCD is the banding effect most(all?) of them seem
    to show when displaying smooth color gradients. Look at a blue sky scene
    and it normally looks a lot smoother on a plasma but has visible bands
    of color across it on LCD and DLP sets. I've seen a lot of burned in
    plasma sets, though that can be minimized by properly setting the
    brightness and contrast. I've also seen a few with irreplaceable parts
    that had craters blown in them. They run at much higher power levels
    than LCD which tends to contribute to more failures.

    .....BUT the resolution, detail and clarity are outstanding on a properly
    working and properly adjusted plasma.... also because it is well suited to
    very large screen size without using the "projection method" it has a much
    wider angle of good viewing without the dramatic light falloff of the
    projection sets whether they are the CRT, LCD and the DLP technologies.
    For smaller screen sizes, the LCD flat panel display, not projection, is a
    clear choice.... just look at the computer's flat panel LCD monitors... the
    newer ones have a much improved response time so movies and fast moving
    scenes don't smear.... but again, if you want big, the Plasma is
    terrific.... I have owned 3 different Plasma sets and NONE have had any
    burn in problems,,,,, but I don't play video games and I vary the
    wide-screen modes every so often to avoid most burn in issues.

    ....anyone know whatever happened to that flourescant or glowing plastic,
    that was discovered and demonstrated 10 or 20 years ago ?
    There was an item on t.v. news detailing how a lab-technician carrying a UV
    lamp was walking past some test tubes containing liquid plastic, noticed one
    / some of them glowed as he walked past. On the t.v. news item, in a
    lab.somewhere, someone in a white coat was holding up a ribbon cable with a
    small glass/plastic panel 2x2 inch? monochrome (in shades of greenscale...if
    you see what I mean), with television motion / images running on it. It was
    speculated that from this be developed into wonderful color flat panel
    displays. without the complications of "traditional" Lcd's / tft's and
    their complicated multi-layer construction etc. ...and the "refresh" rate
    characteristics of this "flourescant plastic" was akin to a CRT. What
    happened to it ?

  10. Thank you all for your will give me a starting
    point.......thanks again....

    They probably couldn't produce the other necessary colors by the same
    chemical process.

    OLED is clearly taking the lead of next gen display tech. It's super simple
    and cheap to fabricate the screens, thinner [and presumably lighter weight]
    than any LCD or plasma TV's I've seen, offers true black, wide viewing
    angle, low power consumption, etc.
    I'm not dumping 3 grand into a plasma set now, when I know (ok speculate)
    that by the time the mandated NTSC cutoff date arrives (2/17/09, last I
    heard), OLED sets will be priced at or below that of competing plasmas.
    Till then, CRT's will serve me well enough.

    and LCD's!

    Dad gummit I hate when the final output is nothing like what the editor
    So er.. yeah.. plasmas AND LCD's will be much cheaper than they are now and
    OLED sets should be priced similarly at that time.

    David Maynard psoted this to my question on "Flourescent displays" in
    alt.comp.hardware.pc-homebuilt :)
    Not sure but it sounds like you're talking about electroluminescent panels.

    The problem for graphic displays and TV is in making the blue color but
    these folks claim to have not only solved that but are in pilot production
    of large screen display panels.

    I would stay away from projection sets .
    My choice for the money in a flat panel wall mount set would be LCD . I
    have seen and handled both at work .

    Plasma is nice but the things weigh a ton .
    LCD is much lighter to hang up . As for funny little effects you see on
    flat panel tv sets once you have one for a couple months you stop
    noticing that . You dont really want to sit 2 feet from a big flat
    screen .

    The only reason i can come up with for having a flat set is .. they are
    just cool and save space and can go up on a wall .
    The biger 36 inch glass tube tv sets ar so big and heavy you need ver
    well made furniture to hold them and if you ever need to move it to hook
    up stuff its a real pain .

    I suggest you look for a flat tv set from a discound outfit , return
    salvage store ( i work at one ) you can save as much as half on
    something with a minor damaged plastic case . My 37 inch sharp has a
    cracked corner which i just glued . Half of retail and it was new in box

    I would say direct view LCDs are more reliable than plasmas. LCD
    technology is more mature and requires much lower voltages and power.
    This makes the ICs that drive the display panel less likely to fail.
    Since these driver ICs are a part of the display panel, they can't be

    I've seen a number of plasmas in stores that had missing bands of
    picture (probably because of a failed driver IC). On the other hand,
    I've only seen a few LCDs with this type of failure (and these were
    from old laptops).
    Andy Cuffe

  17. I would dissagree. The stuff I see in LCDs that I don't like is far more
    annoying to me than PDPs. And the weight is not that much different in the
    same size. Look for yourself and determine which meets your needs. Some
    people prefer the look of one or the other or have priorities that favor one

    You have not handled many of these then .. LCD is always lighter than
    plasma . In fact all the plasma sets i have worked n all had solid cast
    metal frames for the screens . LCD do not have such structures for the
    screen .

    I just worked on a Pana.... Plasma dated Dec. 05 with a 2 inch wide bar
    in the picture .. bad screen on that .
    A second Pana... plasma with bad back lights . This model they built the
    lights in with the screen and will only sell lights & screen as one unit

    I have run across a few non working LCD sets and it was never the screen
    ... yet ...

    Plasma doesn't have backlights, that one must have been an LCD.

    Does Panasonic have anything like the Philips "Ambilight"? If so, maybe
    that's the backlight he's referring to.
