    Most people know plasma TVs as those unbelievably thin display monitors that
    can be hung on your wall just like pieces of video art. (To give you an idea
    of the space-saving advantages of plasma technology, consider this: A
    40-inch TV may be two feet deep and weigh upwards of 150 pounds, while the
    same size plasma display might have a depth of, say, 6 inches and weigh half
    as much.) But this isn't your average slimmed-down television set. The
    display itself consists of thousands of "cells," which are individual glass
    compartments injected with neon-xenon gas suspended in plasma-hence the
    "plasma" appellation. These cells are the basic elements comprising the
    picture you see on your TV screen. When the gases are electrically charged,
    they strike red, green, and blue phosphors. Just like that, an image (which
    is nothing more than the sum of the aforementioned colored elements,
    commonly known as "pixels") is born.
  2. All true but they neglect to mentionj the power consumption. A 50"
    plasma can come in at 700 watts and has necessary cooling fans-- not
    noisy but a nice space heater.

    Nor do they delve into the fragile nature of the display, the high
    possibility of permanent burn-in, the thermal effect of the atmosphere
    surrounding the display, nor the limited life span. Indeed these are awesome
    display devices but before dropping the Euros, Kronas, Pesos, Loonies,
    Dollars, etc it is highly suggested the consumer do some real in depth
    research into the reliability of these devices.
  4. Just buy one. You won't regret it. ;-)
  5. I don't recommend dropping any type of video display.
    Not unique to plasma nor as likely as with older ones.
    CRTs and all projectors get hot, too.
    Projected to be longer than I will want to keep it.

  6. Yeah, somebody, please buy one! Personally, I'm waiting another 5
    years till the lifetimes come up and the prices come down. People who
    buy them today will feel (in a couple of years) just like the folks
    who bought them 2 years ago do now...
  7. Yes but, in 5 years, you will have new technology to find fault with
    and we will have had 5 years of enjoyment. ;-)

  8. Only if you #define Television Enjoyment

    Kal: Referring to the fact that the plasma changes physical characteristics
    when the surrounding air temperature changes, as with a draft caused from
    normal air circulation. Like in a residential home that has forced air
    heating and cooling.<
  10. Ah. I was thinking the other way around. I have not noticed such a
    change but, then again, my room is pretty stable with very little

  11. Who said anything about "Television?"

    Na mão de Spehro Pefhany () é mais barato:
    Here in Brazil a Plasma TV costs about R$ 20000 ($7000) -- the price of a car.
    I think that very few people actually own one.

  13. Not even dropping. I heard of a custodian leaning a broom handle on a
    plasma and breaking the front panel. As far a 'hot' goes, how hot are
    we talking ? A 700 watt plasma will run you around 10 cents an hour
    just to power it up in California (pricy power here). I'm not familiar
    with CRT projectors but I would be surprised if they reached 300
    watts. My 50" DLP runs around 200. The 35" Mitsubishi it replaced was
    195 watts.

    We have several Panasonic 50" plasmas at work and they are wonderful
    RFI generators, I.E don't try to run an AM radio within 10 feet. Also,
    you will notice some odd grainy noise not present in a CRT unit. We
    believe these are by-products of the PWM control.

    You are right about viewing angles and color. And of course, the
    geometry is flawless. LCDs (direct and projectors) and DLPs are also
    excellent on geometry and about half the price of current plasmas. It
    all depends on your preferences and what you're willing to trade off.
  14. Exactly! All these arguments about the 'best' technology are only
    relevant to the situation. In my particular case, plasma was the
    optimum solution. However, last weekend I had a visitor who was
    stunned by the quality of my setup but I advised him to get a FP for
    his room and, after discussion, he agreed.

  15. "Go see Kal, go see Kal, go see Kal!"
  16. Yeah, you're right, I'm in the wrong thread. 8*|
  17. Ah. Well, despite the title of the thread, all the discussion has
    been about display technology applicable to television as well as to
    other sources, such as DVD. When I responded about enjoying the
    plasma for years, there was no mention of television and, in my case,
    the primary enjoyment derives from DVDs.
