what is the difference in LCD And Plasma?And which 1 is better?

Answer 1

For the technical differences, see

http://en.wikipedia.org/wiki/Lcd_display
http://en.wikipedia.org/wiki/Plasma_display

For performance comparisons:

Picture quality of plasma is brighter, better color, better blacks than LCD.
But LCD pictures can look quite good; we’re not talking huge differences.

Sharpness is the same for equivalent pixel counts. Some newer LCDs have 1080 x 1920 resolution, most plasmas still in the 768 x 1024 range.

Plasma is heavier and uses more power than flat panel LCD.

There are reports that plasmas are not as reliable or they don't last as long, but that is no longer true with the latest models. (Both LCD and plasmas have 60,00hr expected lifetime.) Plasma phosphors dim slowly over time (but not as fast as CRT phosphors); but direct view LCDs use flourescent lamps which also dim and eventually burn out (some are replaceable). Projection LCD sets have bulbs of limited life, but are replaceable and the lifetime is a few thousand hours of viewing.

Plasmas are subject to burn-in. A stationary image left on the screen for a long time could produce a permanent ghost image. The most risk is when viewing a lot of 4:3 ratio pictures (non-HD), which are displayed with vertical dark areas on the left and right to fill in the wide screen. Newer plasma designs have minimized this problem and here are ways to avoid it: many sets have a "stretch" mode which widens the picture to fill the whole screen, or will use gray bars instead of black bars. Burn-in also be a problem with extended playing of video games if there is a background image that remains stationary.

Plasmas come in larger sizes, although large flat panel LCDs are coming out, but they are expensive. LCD projectors can be 70".

LCD contrast and brightness can be reduced when viewing from off-center (both flat and projector, but sets will vary). At present, plasmas have very reflective front surfaces which could be a problem in room with lamps and windows that can be reflected by the screen. LCDs look better in bright environments, while plasmas look better in darker rooms.

Answer 2

Liquid Crystal Display, like most flat screen computer monitors, there are actually some fluorescent tubes behind the LCD screen that lights it us so you can see it, Plasma has a gas in the screen,

Which one is better, I think LCD it's not quiet as bright, but it is lighter(weight) and is more durable. If you intend to hang it on the wall.

Another option is DLP its about 15" deep front to back and uses a projection lamp, Great picture, better than LCD or Plasma, There are also LCD projection TVs

But if you want to hang it on the wall forget all the last parts.

Answer 3

Quality is about the same, Plasma is better is low light. LCD is better in more light. Plasma bedroom, LCD family room. Plasma weigh more. If you view a Plasma close up it looks like you are view through a screen. Plasma also can burn in a image. TV life is about the same for both. Plasma are cheaper. Plasma look better at a sharp angle.

I wouldn't let LCD/Plasma be the decider factor when buying one.

Answer 4

There's no answer to which one is better. It's a matter of personal taste & preference. Let you own eyes be the judges. Shop around and compare picture quality. To me, plasmas are better to watch DVD's and HD programming, LCD's are better to play video games on, and both are good to watch regular TV on.
