Crt beam computer
WebCathode Ray Tube (CRT) is a computer display screen, used to display the output in a standard composite video signal. The working of CRT depends on the movement of an electron beam which moves back and forth across the back of the screen. The source of the electron beam is the electron gun; the gun is located in the narrow, cylindrical neck at ... WebThe main element of a video monitor is the Cathode Ray Tube (CRT), shown in the following illustration. The operation of CRT is very simple −. The electron gun emits a beam of electrons (cathode rays). The electron beam passes through focusing and deflection systems that direct it towards specified positions on the phosphor-coated screen.
