  • A beam of electrons emitted by an electron gun, passes through focusing System and deflection systems that direct the beam toward specified positions on the phosphor-coated screen.
  • The phosphor-coated screen then emits a small spot of light at each position contacted by the electron beam.
  • The light emitted by the phosphor fades very rapidly, the picture is redrawn by quickly directing the electron beam back over the same points. This type of display is called a refresh CRT.
