How does the cathode ray tube work?
A CRT is a presentation screen that produces pictures as a video signal. It is a sort of vacuum tube that display pictures when electron beams from an electron gun strike a luminous surface. In other words, the CRT produces beams, accelerates them at high speed, and deflects them to make pictures on a phosphor screen.
