The origin of TV, what is the origin brand of TV?

Baird, a native of Scots, was smart and studious since he was a child, and he was very interested in radio. In 1925, he made the world's most primitive television camera and receiver by carefully designing and using waste materials such as old radio equipment, old sugar boxes, bicycle lamp lenses, and old wires. In the experiment, a miracle occurred, and an image appeared on the phosphor screen.

On January 27, 1926, Baird presented his invention to a group of 40 scientists at the Royal Society in London. He was playing a TV in one room and the scientists were in another**, and a person smoking and talking appeared on a fluorescent screen. This performance was later internationally recognized as the first public day on television.

The original TV cameras and receivers were only three yards apart, and the images were blurry. Baird's family was poor, and in order to raise funds for his research, he agreed with a shop owner to put on a television in the store every day to attract customers. He was paid twenty-five pounds a week.

Baird used all the money to buy materials, improve equipment, and continue to conduct research and experiments on television. In 1929, Baird's research made significant progress, using antenna radio waves to send television images from London to New York, where New Yorkers saw London on fluorescent screens. At the time, the news caused a sensation around the world.

Since then, television has quickly developed in countries around the world.

The fruits of the second scientific and technological revolution.

The earliest television set in China was the "Beijing brand" black-and-white television set.

In the mid-50s of the last century, there were more than 500 TV stations and 40 million TV sets around the world. However, at this time, China's television broadcasting was still in a blank state.

In 1957, the state decided to develop the television broadcasting industry and handed over the task of developing television receivers to the Tianjin Radio Factory. In March 1958, Tianjin Radio Factory trial-produced the first domestic TV - "Beijing Brand" 820 35cm tube.

The black-and-white TV was successfully tested on March 17.

Extended Information: The first television station.

On May 1, 1958, China's first television station, Beijing TV.

On November 2, 1958, the announcer made his first appearance to broadcast the news, and Shen Li, who was in charge of broadcasting that day.

Became the first TV announcer in China.

In 1906, the Scottish young Baird set up a humble laboratory with the intention of making a television set. After more than ten years of hard work and hard work, in 1925 he finally built the world's most primitive television camera and receiver from waste materials such as old radio equipment, old sugar boxes, bicycle lamp lenses and old wires. <

In 1906, the Scottish young Baird set up a humble laboratory with the intention of making a television set. After more than a decade of hard work, in 1925 he finally built the world's most primitive television camera and receiver from waste materials such as old radio equipment, old sugar boxes, bicycle lantern lenses and old wires.

In the trial, images are displayed on a phosphor screen. On January 27, 1926, Baird performed his invention to 40 scientists at the Royal Society in London, England. He was playing a TV in one room, the scientists were in another**, and a person smoking and talking appeared on a fluorescent screen.

In 1925, British engineer John Logie Baird invented the world's first television set, the mechanical television.

In 1939, the Swiss Philip of the United States invented the first black-and-white television set.

In 1954, the Texas Instrument Company of the United States developed the first color television.

In 1958, the then state-owned Tianjin Radio Factory produced China's first black-and-white television set.

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

At the end of the 80s, because it was difficult to achieve a large screen for CRT TVs, Japanese companies launched rear-projection TVs with the reality technology of transmitting imaging, and rear-projection TVs were all the rage.

Now TV has developed in the direction of informatization, cloud TV, network TV, artificial intelligence TV, technology continues to promote the new form of TV.
