The television set is a machine that utilizes electrical methods to disseminate optical information according to the visual transient characteristics and visual psychology of the human eye. The basic system of a television set consists of 3 parts: camera, transmission and visualization.
Invention
The first television
The television set was invented independently by each of the three men, Ferro Farnsworth, Viratimir Sforokin, and Baird, but there is a difference between the three inventions; Baird's (whose full name was John Logie Baird) television was a mechanically-scanned television, and Ferro Farnsworth and Viratimir Sforokin's television was electronic television. The birth of television is usually regarded as a sign of its birth when Scotsman John Logie Baird "scanned" images of puppets in an experiment in London on October 2, 1925, and he has been called the "Father of Television". But this view is controversial; it was also the year that the Russian Vladimir Zworykin (who showed his bosses his TV system at Westinghouse) and Ferro Farnsworth invented television in 1927.
Despite the same timing, John Logie Baird's television system is very different from those of Vladimir Zworykin and Ferro Farnsworth. History refers to John Logie Baird's television system as mechanical television, while Vladimir Zworykin's and Ferro Farnsworth's television systems are referred to as electronic television. This difference is mainly due to differences in transmission and reception principles.
The first television set came out in 1924, invented by the British electrical engineer John Baird, by 1928, the United States of America's RCA television station was the first to broadcast the first set of television films "FelixTheCat", and from then on, the television set began to change the life of mankind, the dissemination of information and the way of thinking. From then on , mankind began to step into the era of television. From black and white to color, from analog to digital, from spherical to flat.
The development of television is complicated. In 1928, Baird's company produced the Baird Model C, the world's first mass-produced television set.
The first color television
In 1954, the United States, Texas Phase Instruments (RCA) developed the first all-transistor television receiver RCACT-100, which used the NTSC system, the year in the United States Westinghouse sold for $1,000. At that time, television tubes were very expensive, and RCA lost money on every television, but when the new samples came on the market, they recovered twice as much in a very short time.
