Braun Tube (Cathode Ray Tube : CRT) is a kind of a display component Transforming electrical signals into light signals.

It has an electron gun inserted into the cathode and the electron gun is a device generating Thermal electrons. It emits cathode electrons (thermal electrons), which are attracted by strong positive electricity and scanned along the tube. During this process, DY(Deflection Yoke) deflects electrons in every direction and make possible 2-dimensional display. Electrons hit the phosphor-coated surface of the screen radiating the phosphors and displaying images such as letters or figures on the screen.
