Detailed explanation-1: -The full form of CRT is Cathode Ray Tube. CRT is a vacuum tube in which a fluorescent projector produces a trace of an electron beam, deflected by induced magnetic and electric fields.
Detailed explanation-2: -A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms (oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena.
Detailed explanation-3: -The function of the cathode-ray tube is to convert an electrical signal into a visual display. The tube contains an electron-gun structure (to provide a narrow beam of electrons) and a phosphor screen.
