what is a crt in computers
Definition of: CRT (1) (C RunTime) See runtime library. (2) (Cathode Ray Tube) A vacuum tube used as a display screen in a computer monitor or TV. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. In the past, CRT was a popular term for a computer display terminal. Today, monitor is the correct term as computer displays have long since migrated from CRTs to LCD panels (see flat panel display). Likewise, TV sets no longer use CRTs (see flat panel TV).
