CRT Television:
CRT is an abbreviation that stands for "Cathode Ray Tube", and has been the main form of television technology for many years. A CRT is a heated filament, the cathode, inside a vacuum glass tube. The stream of electrons, the ray, is poured off into the tube and then is "steered", so to speak, by the steering coils. They are directed at a screen that is coated with phosphors. The phosphors then become excited, which causes them to light up. This gives you the TV picture display.
CRT Television comparison to Laser TVs:
In contrast to CRT TVs, which use a cathode ray tube, laser televisions are based on the projection-television systems using DLP technology. Instead of using a CRT (cathode ray tube), laser-TVs use a powerful array of 3 lasers that emit beams of red, green, or blue light. The result is that lasertelevisions have images that are brighter and deeper, having a richer, more vibrant color palette than a conventional CRT TV. Due to using lasers and not large CRTs, laserTV displays can be displayed on large, thin, lightweight screens, making laser-TVs ideal for wall mounting and not so big and bulky as CRT televisions.
