The traditional television set is known as a cathode ray tube, or CRT. Unlike plasma screen televisions, CRT tube televisions use a beam of electrons to illuminate phosphors to form a picture. The electron beam excites the atoms of phosphor on the screen, causing a picture to form. The beam of electrons must constantly scan the screen to refresh it, producing scan lines. A CRT can produce excellent images, but it suffers from size constraints – the larger a CRT screen, the larger and deeper the tube itself has to be. This means that very large CRT screens can end up taking up undue amounts of space.
