What is the history of television? History. The history of the development of television

At the end of the 19th century, a handful of pioneers began to work on the design of technology for transmitting images;

In 1904, the Englishman Bellewell and the German Cologne invented the television technology of transmitting a silver bridge jujube ** on a television machine;

In 1924, British and German scientists succeeded in producing still images using mechanical scanning almost simultaneously;

In 1923, the Russian-American scientist Zvorykin applied for a patent for a photoelectric picture tube, a television transmitter and a television receiver, and he was the first to adopt a comprehensive "electronic television" transmission and reception system, becoming a pioneer of modern television technology.

In 1925, British scientists successfully developed a television set;

In 1928, 31 radio stations in New York, USA, conducted the world's first experiment of eliminating television broadcasting;

In 1929, American scientist Yves Feng invented the color television set by broadcasting 50 lines of color television images between New York and Washington;

In 1933, Zvorikin developed a video tube and a picture tube for television cameras;

In 1939, the United States launched the world's first black-and-white television set;

In 1953, the national standard for color TVs was set;

In 1954, color television was introduced.

In 1924, the British inventor Baird invented the world's first television set - the mechanical television.

It works only by mechanical scanning to capture images, with a resolution of 30 lines and a repetition rate of 5 frames per second, so the first TV was not really an electronic product.

In 1933, Zvorikin successfully developed a camera tube and a picture tube for television cameras, and invented the prototype of modern television - electronic television.

In 1958, Tianjin Wireless Electronics Factory manufactured China's first black-and-white television set, named "Beijing", and was known as: "China's first screen".

In the same year, the TV station began a trial broadcast.

In 1970, China's first color television set was also born in Tianjin.

At that time, Tianjin could be said to be a gathering place for technicians.

And the world's first color TV was the CT-100 of the American Radio Company.

12-inch screen, the time is 1954, 16 years earlier than China.

In 1981, Japan's Sony Corporation developed a compact black-and-white television that uses an LCD screen of only inches and is powered by batteries.

In 1988, China successfully launched a synchronous satellite.

Two years later, the satellite relayed the live launch of Asiasat-1, which kicked off the prelude to China's satellite television.

In 1990, the country's first provincial cable TV Hunan cable radio and television station began trial broadcasting.

The establishment of cable stations broke the situation of TVB dominating the world.

Subsequently, the display technology developed from color TV to plasma TV and LCD TV.

In 2008, Hyundai debuted a consumer-grade 3D TV in Japan, the 46-inch E465S, which requires glasses **3D effect.

In May 2013, Shenzhen Zhangwang Technology Co., Ltd. successfully developed 4K naked-eye commercial 3D TV, which can realize free switching between 2D and 3D.
