Oh sorry... A wire with an electrical current going through it is heated up so it gives off electrons. These electrons are then attracted towards a cathode through electromagnetism. THey fire you a very small hole in the cathode to hit the screen. Where they hit, they cause the reactive chemical to give off light in one of three colours, red green and blue. Pixels are made up of dots of each of these chemicals. The stream of electrons is deflected up and down and sideways by electromagnetic plates.
Enough?
