CATHODE RAY TUBE MONITOR TV

Over time, other scientists discovered that CRTs could be used to display moving images without the need for mechanical moving parts, which was a key part of commercializing television. Braun diagram of his original cathode ray tube design from 1897. In 1897, a German engineer named Karl Ferdinand Braun added a phosphorescent screen and magnetic deflection control to create the first cathode ray tube, which he used to display the waveform of alternating current like an oscilloscope.

Why 'cathode rays'? Before the discovery of the electron, scientists called the flow of electrons 'cathode rays', because these mysterious rays were for the first time emitted by a cathode (a negatively charged electrode), casting shadows inside. When someone says 'a cathode ray tube' they can also refer to a television or monitor that uses a cathode ray tube instead of the cathode ray tube itself. CRTs are electronic image display devices that have the advantage of dynamically displaying information without the need for moving parts.

CATHODE RAY TUBE MONITOR TV

It's a technical term for the glass picture tube inside a vintage TV or computer monitor - the type used before flat screens became mainstream. In the context of electronics, CRT stands for 'cathode ray tube'.
