What Is CRT?
CRT is short for Cathode Ray Tube. A color CRT TV is built around a cathode ray tube, which is a large vacuum tube with three electron guns on one end and a flat or slightly curved surface on the other end covered with carefully arranged phosphor dots that glow red, blue, or green when struck by electrons. Each electron gun, one for each color, emits an electron beam, that, directed by electro-magnets, moves very rapidly back and forth across the phosphored end, causing the phosphor dots to glow in a line by line fashion. The accumulation of lines, up to 1080 in 1/30th of a second or less, creates the picture you see on a CRT screen.
