At the end of 19, a few pioneers began to study and design the technology of transmitting images. 1904, an Englishman, belleville, and a German, Kelon, invented a TV fax technology. Each photo needs 10 minute to fax one photo at a time. From 65438 to 0924, British and German scientists successfully transmitted still images by mechanical scanning almost simultaneously. However, the transmission distance and range of cable mechanical TV are very limited, and the image is quite rough.

1923, Russian-American scientist Zworykin applied for the patent of photoelectric picture tube, TV transmitter and TV receiver. He adopted a comprehensive "electronic TV" transmitting and receiving system for the first time and became a pioneer of modern TV technology. With the application of electronic technology in television, television began to go out of the laboratory and enter public life. 1925, British scientists successfully developed TV sets. 1928, 3 1 radio stations in new york, USA conducted the first television broadcasting experiment in the world. Because CRT technology has not completely passed the test, the whole experiment only lasted for 30 minutes, and only a dozen TV sets were watched. This announced the emergence of TV art as a social undertaking and an epoch-making event in the history of TV development.

From 65438 to 0929, American scientist eves played 50 lines of color TV images between new york and Washington, and invented color TV. 1933, Zworykin successfully developed camera tubes and picture tubes for TV camera shooting. The process of making TV camera and imaging completely electronic has been completed, and so far, the modern TV system has basically taken shape. Today, the imaging principle and equipment of TV cameras and TV receivers are improved according to his invention.

American RCA 1939 introduced the world's first black-and-white TV, 1953 formulated the national color TV standard, and 1954 introduced RCA color TV.

1924, British electronic engineer john baird invented the first TV set, and the first TV series was broadcast in the United States on 1928. Since then, television has changed human life, information dissemination and way of thinking. Since then, mankind has begun to step into the television era.

The invention of television may not be the greatest invention of scientists, but it should be the greatest invention of human participation. Through the invention of television, we have narrowed the distance with the world, and the development of related industries triggered by it is unimaginable. We must admit that television has completely changed people's lives.
