LCD or Plasma? (For PC use)

[Guest]

Hi,

Our lab is planning to buy a large screen display (about 40"),
to demonstrate the experiment result. The video input will be
from PC.

Could anyone give me some suggestion on which one to buy?

Thanks a lot!

What's most important to you? Resolution? Color accuracy?
Viewing angle? Brightness? Contrast? Power? Weight?
Cost?

And, further, if it is intended as a "large viewing audience"
application,
there are other technologies that may be more versatile - such as LCD or
DMD front or rear screen projection.
Hard as we may try, it has been impossible to date to get inside another
person's thoughts.... so a better description of the use or need will allow
the
suggestions to be more appropriate and (we hope) helpful.

Thank you very much for your help, and I'm sorry for not making this
clear.

The main purpose is to demonstrate some simulation experiments to
visitors, my boss wants it to be large enough so he and a few (two?
three?, not many) guests can stand in front of the display while he
explains the experiments to them.
It needs not to be like a formal presentation, in which case we can use
a projector.
The display is kind of static, not highly dynamic.

The major issues I think may be resolution (when input is from PC),
viewing angle, and weight.

Thank you for any suggestions.

OK, now I think we may be able to help a bit.

The biggest difference between plasma and LCD at this size will
be resolution and cost. In the 40" range, the highest-resolution
plasma display that will be readily available will be something
around a wide-XGA, or about 1366x768 pixels. LCDs will
be available in either this format or the "full HD" 1920 x 1080.
So if you really need to display in the "highest resolution" possible,
you'd have to go with the LCD.

For typical products of both types in this size range, plasma will
still most often have a slight edge in brightness, contrast, and
viewing angle, although the LCDs are catching up very rapidly
on all counts. Plasma will also still have the advantage in cost,
but will be significantly heavier and thicker, and will require
more power.

Only my personal $0.02; I'd recommend, at this point, that you
get to a dealer who has both types in the desired size range,
and do a side-by-side comparison with the sorts of images
you'll be most interested in (take your own laptop as a source
of "PC" images, if you like).

The only full HD LCDs of which I'm aware unless you're talking very high end
equipment not normally available on the consumer market would be the 45"
Sharp Aquos.

The reason for suggesting projection devices is they may be more
economic,
in case that is a consideration. However, most of them only operate at 800
by
600 or 1024 by 768 pixel formats, so if detail is important, they may not be
desirable.
Large screen plasma or LCD's will tend to cost well over $1k, whereas
there
are projectors generally available for less than $1k (at least until you
factor in
replacing the lamp..(!!).

One other point - consider the directionality of the display, and either
plasma or
DMD projection are likely to be attractive for that point. LCD's still
suffer a lot
of image degradation when you view off-axis, as would be the case if there
are
several viewers at the same time. Plasma is closest to a CRT in performance,
because of using phosphors. DMD will depend on the "gain" of the RP screen.
DMDs also tend to have "smoother" image spatial transitions (you can usually
not distinguish individual pixels like you can with plasma & LCD).

Like Bob suggested - go take a look (if you are located where that is a
convenient possibility).
