How does a plasma TV work? It works very similar to a standard television set, except instead of a large cathode ray tube, they use a flat plasma panel, consisting of millions of small, tiny cells, very similar to fluorescent light bulbs. These cells are illuminated by a certain electrical charge, that's input into the panel, either on the side, or the bottom, or top. Plasma displays are different than an LCD, in terms of power consumption, and heat generation. They do require a little bit more electricity to run, and they get a little bit hotter, but they do produce a extremely bright and vivid screen. Also, they're excellent for reproducing very fast moving objects, especially sporting events of that nature. They also have the ability to reproduce over one million different colors, so the realism of the image is stunning. As you can see, this is a 42 inch TV, and you can see that this is a lot thinner than the older CRT tubes, that can be easily mounted on a television stand like this, and can be easily mounted on the wall. As you know, the older CRT tubes, you could barely pick one up, actually they only made them in 40 inch size. I don't believe they made anything larger than 40. This happens to be a 42, and I can pick this TV up myself, and move it easily.
