So how do plasma TV's work? Believe it or not the concept of plasma displays had been invented as long ago as the 1930's, Not quite 21st cutting edge technology! The idea is that instead of using electrons to create lines, the plasma screen uses three fluorescent light cells, one in each primary colour.

Plasma displays are considerably shallower than older TVs, you can mount them on a wall and conveniently hide them behind a well-placed curtain. They can also be scaled up by adding more pixels and enough power to run them. The biggest plasma TV we found was a 152 inch! That's pretty much 3 meters long and will set you back a measly £380,000.

I bet your TV is not as big as 152 inches! If you enjoyed this vid then why not give us a thumbs up or share it with your friends.
