The invention of television can be traced back to1the end of the 9th century and the beginning of the 20th century. Although many people have contributed to the invention of television, there are two names that best represent the inventors of television: vladimir zworykin and John Logie Baird.
1923, Zlum applied for a patent for television imaging. 1930, he made the first TV imaging tube-kinescope. This kind of picture tube was applied to TV sets at that time and became an important image display device of TV sets. Baird is also doing similar work. He invented a mechanical TV set and demonstrated it successfully in public in 1925.
However, it was not until after World War II that television gradually became popular. 1947, General Electric Company of the United States introduced the first commercial TV set, which used black and white images. Soon after, color TV came out. With the continuous progress and perfection of technology, the resolution and color of TV sets have been greatly improved, and TV sets have gradually become an indispensable part of people's lives.
