Crt Screen Schematic

Cathode ray tube essentially consists of an electron gun for producing a stream of electrons focusing and accelerating anodes for producing a narrow and sharply focused electron beam horizontal and vertical deflection plates for controlling the beam path and an evacuated glass envelope with phosphorescent screen giving bright spot when struck by a high velocity. This high velocity beam strikes the fluorescent screen thus causing a luminous spot on the screen.
