what is the diff. between plasma and LCD tv.which one is better?

Answer 1

To learn the technology of the two display types ,see

http://en.wikipedia.org/wiki/Plasma_TV
http://en.wikipedia.org/wiki/LCD_display

For a summary of the difference in performance of the two types of sets:

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

Both previous answers are somewhat misleading.

Plasma and LCD are different types of flat panel displays based on different priciples, and both are similar priced at the size range where both are available. Things are always changing as technology evolves, but LCDs are generally available from small TV size screens (<20") to moderate sizes (ca 45"). Plasma are not available in small sizes (< ca. 30") and are the only practical (although expensive) choice at about 50" and up.

Plasma used to be subject to burn-in, but displays made in the last couple of years have special features to prevent that.

The link below (plasma.com) has a brief description of how LCD and Plasma screens work.

In the size range most people want (and can afford) both LCD and plasma models are available, so you have to decide for yourself which is better for your needs.

In general I find plasma diplays to give a richer, higher contrast picture than LCD, but I rejected both since I personally prefer a true "big picture" only available through a projector. My home theatre has a 110" screen and cost no more than a plasma or LCD TV a fraction of that size.

Keep asking questions, do more reading and remember your particular requirements may make a big difference in the choice of what will work best for you. Don't just take someone else's opinion. Decide for yourself. Good luck.

Answer 3

Princess what are you on about?!?!?

LCD (liquid crystal display) Not projection, that would involve a large plain white screen that a "projector" "projects" onto!

Plasma is bad in my opinion, beacause the image is "burned" onto the screen so lets say for example you're watching a soccer match for 90 mins then after the game is over you will still be able to see the score faintly on the top of the screen when you begin to watch whatever you plan to watch next.
With LCD you won't have this problem. Also plasma screens tend to be over-priced and more likely to screw up.And when they do they're expensive to have fixed. So if you do go against my advice and get a plasma then make sure you get the full guarantee and warantee with it

Happy viewing! :)

Answer 4

the plasma is a flat screen TV
a LCD is a projector
and the plasma is better
