what is the difference between lcd and plazma television?? what criteria does one see while purchasing one???

Answer 1

plasma is more advanced technology..viewing pleasure is not very different though..think plasma has more colors than lcd and plasma is more costlier.

Answer 2

Here is a summary of the differences based on the latest information:

Picture quality of plasma is still brighter, with better color and better blacks than LCD. but LCD is continuing to improve. 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. 1080i and 1080p plasmas in the 50' range are just coming out but they are expensive.

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).

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; some think that it is no longer a consideration. There 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. Again, LCD is making progess here.

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.
