Plasma screens are made of two sheets of glass, between which Plasma (xenon and neon gas) fills thousands of tiny chambers. Behind each chamber are a series of red, blue and green phosphors. When electricity hits the Plasma chambers, they emit invisible UV light, which then hits one of the coloured phosphors. This creates a visible image on the screen.
LCD stands for Liquid Crystal Display. A network of hundreds of thousands of tiny LCD pixels sits behind the TV screen. Behind these pixels is a fluorescent white backlight. When the light hits the pixels, an electric current determines what colour appears on the screen, and the millions of tiny light variations make up the image that you see on your TV.
What is the main
advantages of Plasma over LCD?
Larger screen size availability – Plasma screens range from 32" up to 65" (Manufacture dependant).

Better colour accuracy and saturation.
Better motion tracking (little or no motion lag in fast moving images).
What is the main disadvantages of Plasma over LCD?
Plasma TVs are more susceptible to burn-in of static images.
Plasma TVs generate more heat than LCD, due to the need to light of phosphors to create images.
Does not perform as well at higher altitude.
What is the main
LCD television advantages over plasma?

Cooler running temperature.

What is the
main disadvantages of LCD over Plasma?
Lower contrast ratio, not as good rendering deep blacks.
