What is the difference between a plasma T.V and a LCD?

Answer 1

To learn the technical differences see

There is now very little advantage to either. Do not believe rumors about plasma "leaking gas" or needing "recharging". New plasmas are just as reliable as LCDs Here is a summary of the key features of each:

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

A plasma TV works by the excitation of gas molecules inside the unit. However the gas slowly leaks out over time and when the gas is gone the TV can't be used any more. LCD or liquid crystal display, works on the same principle as many digital watch or calculator screens. Fine crystals are suspended in a liquid, and voltage can be applied in a certain way to make the crystals rearrange themselves.

Answer 3

One is Plasma and one is Liquid Crystal Display!

Sort of self explanatory really???

I think by and large you get a better picture out of LCD but they do not go above a certain size and that's where the plasma comes in???

Answer 4

plasma hd tvs have over amillion pixels that are like little light bulbs that have up to five differnt gases in them when charged they turn on producing up 25 millions colors or more when they dont leak there gases you cant recharge them they last over 60000 hours that watching tv 7 hrs aday for 18 years, lcd have 3 differnt panels with a light bulb always on when it neen to show a color the panel opens like a shutter to produce it color becauxe of that lcd dont reproduce a true black because alittle light leaks in while plasma either on or off creating a true black both last long time lcd are in small sizes up to 50" while plasma start at 37" to 70" this is simple way to explain tvs but this is what i do all day long selling tvs for over 18 years

Answer 5

Ok, my friend explained this one to me in laymens terms.

Plasma is better becuase you can look at the tv from different angles and still see the image. However, if you have an LCD screen, it's like your computer laptop--if you look at it from an angle, the picture is hard to see.

that's why plasma is more money...it's better

Answer 6

LCD TVs r new technology
