A '''Cathode Ray Tube''' (usually '''CRT''' for short) is a now-obsolescent display technology that was the mainstay of visual output devices for a century, until displays consisting of [[array]]s of [[Light Emitting Diode|LEDs]], etc, became available economically.

It consists of a large [[vacuum tube]], with a large face covered with a ''phospor'', a phosphorescent powder. An electrode at the base of the neck (back) of the tube produces a beam of [[electron]]s, which are shot into the phosphor; where the beam hits, the phosphor produces a spot of light.

The beam can be scanned across the face by means of [[electrostatic]] or [[magnetic]] control grids through which the electron beam is sent.
