Cathode ray tube (CRT)

Cathode ray tube (CRT)
A tube, usually glass, which is narrow at one end and widens at the other to create a surface onto which pictures can be projected. The narrow end contains circuits to generate and focus an electron beam on the luminescent screen at the other end. Used to display pictures in TV receivers, video monitors, oscilloscopes, computers, etc.
