The differences between LCD and plasma TVs

Although both offer similar advantages over traditional TVs, there are some key differences between LCD and plasma screens:

How does an LCD TV work?
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.

How does a plasma TV work?
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.
