Both Plasma and LCD technologies attempt to deliver the same (similar, in any case) results; both are used in televisions that are flat and thin. Here you can read side-by-side list of what each has to offer that the other one does not.
Plasma Television Overview
1. Plasma displays are made up of cells that contain glass panels. There’s a narrow gap between the panels that’s filled with neon-xenon gas in plasma form. This gas is charged when the Plasma TV is in used electrically. This charged gas strikes phosphors (red, green and blue) producing a TV image. Each red, green and blue phosphor is a picture element, better known as pixel.
2. So Plasma TVs burns phosphors to generate images. Which means, it has some of the negative quality of traditional TVs, specifically: you get heat and screen-burn of static images.
3. The screen does emit radiation.
LCD Television Overview
1. LCD displays are made of layers (2) of transparent material that are polarized and ‘glued’ together. One of the layers is coated with a substance (polymer) that contains individual liquid crystals. When electric current is passed through the individual crystals, they allow light to pass through or block it. So once you have the panels properly set, you put a light source (florescent bulb) net to it and the image the LCD creates becomes visible.
2. The liquid crystals produce less heat than the phosphors of Plasma or CRT televisions. The light source that makes the images visible uses less power.
3. The screen does not emit any radiation.
