The difference between LCD TVs and plasma TVs is not readily apparent. They look quite similar, but use entirely different technology. A plasma TV is made up of cells, which have been injected with a gas called neon-xenon . When electricity is applied to the cell, red, green and blue phosphors are struck. Each of these is called a pixel, and together they comprise the picture.

When LCD televisions first came on the market, the smaller screens were not only more widely available, but were more reasonably priced. The technology needed cause the large screen TVs to be more costly. With advancement in the technology, the price differences have evened out, making the larger sized LCD television economically feasible.
