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.

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.

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 ?

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.

Dad gummit I hate when the final output is nothing like what the editor
shows!!
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 :)
<quote>
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. http://www.ifire.com/

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
replaced.

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).

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
technology.

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.
