|---|
| Cathode Ray Tube. A vacuum tube which produces light when an electron beam hits its internal surface. A ''gun'' which creates electrons and a high voltage source that accelerates them generate the electron beam. The CRT is used as a picture displaying tube in video monitors, TV sets, computer monitors and others. It is assumed that the CRT will be replaced in the future by flat displays – such as LCD/TFT, Plasma or other modern types. |
