The development course and history of TV set

1924, British inventor Baird invented the world's first television-mechanical television. Its working principle can only be shot by mechanical scanning, with a resolution of 30 lines and a repetition rate of 5 frames per second, so the first TV was not actually an electronic product.

1933, Zworykin successfully developed the camera tube and kinescope used for TV camera shooting, and invented the embryonic form of modern TV-electronic TV.

From 65438 to 0958, Tianjin Wireless Electronics Factory produced the first black-and-white TV set in China, named "Beijing", which was known as "above the fold of China". In the same year, the TV station began a pilot broadcast.

1970, the first color TV set in China was also born in Tianjin. At that time, Tianjin was a gathering place for technicians. The first color TV set in the world was CT- 100 of American Radio Company. 12 inch screen, time is 1954, earlier than China 16 years.

Extended data:

Judging from the development of TV, the display technology is becoming more and more mature. So far, LCD TV has occupied most of the consumer market, and naked-eye 3D display is still in the development stage.

The continuous innovation of technology will continuously promote the development of naked-eye 3D industry. At the same time, it also means that the commercial application of naked-eye 3D display will be greatly developed in both scale and depth, and will be widely used in more fields.
