CRT or Cathode ray tube consists of cathode, control grid, accelerating anode, focusing electrode, horizontal deflection plates, vertical deflection plates and phosphor coated screen. Cathode and control grid produce a beam of electrons. Accelerating anode accelerate the electron beam. Horizontal deflection plates move the electron beam in horizontal direction. Vertical deflection plates move the electron beam in vertical direction.

Cathode ray tube (CRT) is a vacuum tube using cathode rays to generate a picture on a fluorescent screen. These cathode rays are in fact the electron beam deflected and modulated, which impinges on a phosphor screen to generate a picture according to a repetitive pattern refreshed at a frequency usually between 25 and 72 Hz. (CRT) Vacuum tube used to display data in a visual form. Picture tube of a television or computer terminal.
