INVENTION OF CATHODE RAY TUBE

INVeNTION OF CATHODE RAY TUBE

Karl Ferdinand Braun

v Today, TV and computer screens are made of liquid crystal display that is flat and light. It's called LCD. Before it was invented, the cathode of the monitor or TV screen cathode was from the tube. It was heavy and square like a box. But that was the foundation of the invention of monitors and TVs. The cathode ray tube is a solid glass sphere.

v The flat part on one side is called the screen. It has an electric gun on its end. The inside of the screen of the tube contains phosphorus particles. Electron guns carry three rays from the base red, green, and brown. It forms a picture by processing it with phosphor particles. The cathode ray tube was invented by a scientist named Carl Brown. He was awarded the Nobel Prize in Physics along with Marconi for the discovery.

v Carl Ferdinand Brown was born in Fulda, Germany, on June 6th, 6th. After receiving his higher education at the University of Marburg, he received a PhD degree from the University of Berlin. In 740 he joined the University of Strasbourg as a professor.

v Carl Brown invented the cathode ray tube in 7.8, also called the brown tube. The inventor of the radio, Marconi, adopted many of Brown's theories. During World War I, Carl Brown went to America. He was appointed to a German wireless station in New York. He was detained in the United States during the war. After the war, it was established in the United States. He died in the United States on April 7, 865.
