Who Invented The Television? History Of Television - Biography of John Logie Baird

Who Invented The Television? History Of Television - John Logie Baird. The television we see today is a technological result invented by some experts in the electronics field. The basic idea of ​​a television was first coined by Paul Gottlieb Nipkow, a 23-year-old student in Germany, who patented an electromechanical television system using Nipkow's discs. But the famous television inventor who has been widely accepted by the world as the first television demonstration is John Logie Baird. In Indonesia 'television' is not formally called TV (read: tivi, TV or tipi.) 

Here are some prominent scientists in creating television towards perfection: 

1880s: Nipkow Discs

In 1884, Paul Gottlieb Nipkow, a 23-year-old student in Germany, patented an electromechanical television system using Nipkow's disc, a rotating disc with a series of holes arranged spirally to the center of the claws used in the process of engraving. Each disc hole is positioned by the same angular difference so that in each rotation the disk can pass light through each hole to the light-sensitive selenium layer that produces an electrical pulse. Along with the positioning of the focused image at the center of the disc, each hole will scan every horizontal "slice" of the entire image. Nipkow's artificial tool is not really practicable until there is progress in the amplifier tube technology. However, the tool can only emit images "the phone . 

The next design is to use a rotating mirror-drum scanner as an image recorder and cathode ray tube (CRT) as a display device. In 1907, a Russian scientist, Boris Rosing, became the first inventor to use CRTs in a receiver device from an experimental television system. He uses the "mirror-drum" scanner to send simple geometric images to the CRT. However, to record moving images is still not possible, due to the low sensitivity of the selenium detector. 

1920s: The Discovery of John Logie Baird

The Scottish inventor John Logie Baird manages to show how a motion-image shadow moved in London in 1925, followed by a monochrome moving image in 1926. Baird's scanning disks can produce 30-line resolution images (enough to show human faces) of the lens with a double spiral .

This demonstration by Baird has been generally accepted by the world as the first television demonstration, even if the mechanical television is no longer in use. In 1927, Baird also invented the world's first video recording system, "Phonovision", by modulating its TV camera's output signal into the range of audio range, he can record the signal on a 10-inch (25 cm) audio disc by using ordinary audio recording technology. Only a handful of Baird's existing "Phonovision" records and surviving recordings were then translated and processed into images that could be seen in the 1990s using digital signal-processing technology.

In 1926, a Hungarian engineer, Kálmán Tihanyi, designed a television system with a fully electronic scanning and display device, and used the "content storage" principle in the scanner tube (or "camera"). 

In 1927, a Russian inventor, Léon Theremin, developed a television system with mirrors that employed a "video interwoven" system to produce a 100-line image resolution.

That same year, Herbert E. Ives of Bell Labs managed to transmit moving images from a 50-lattice disc that produced 16 images per minute via cable medium from Washington, DC to New York City, and also through radio waves from Whippany, New Jersey . Ives uses a publisher screen of 24 x 30 inches (60 x 75 cm). Recording subjects included one of the then American Trade Secretaries, Herbert Hoover. 

In the same year, Philo Farnsworth succeeded in creating the world's first television system with electronic scanners on both display and pickup devices, where it was first demonstrated in front of the press on September 1, 1928. 1930s: Community dissemination and acceptance

In 1936, for the first time the Berlin Olympics was broadcast to television stations in Berlin and Leipzig where the general public could watch each race directly.

In the early days of television, electromechanical television sets started commercially from 1928 to 1934 in England, the United States and Russia. The first commercial television was sold by Baird in Great Britain in 1928 in the form of a radio receiver coupled with components such as a fluorescent tube on the back of a Nipkow disc that produced a reddish-sized image of postage stamp that could be re-enlarged using a magnifying lens. Baird's "Televisor" can also be used without radio. Televisors sold in 1930-1933 were the first mass marketing of television. Approximately 1,000 units of Televisor were sold.

The first commercial electronic television box with cathode ray tube was manufactured by Telefunken in Germany in 1934, followed by other electronics manufacturers in France (1936), Great Britain (1936), and United States (1938). In 1936, Kálmán Tihanyi explained the principle of plasma television, the first flat panel system. In 1938 in America, a 3-inch (7.6 cm) television set sold for 125 USD (equivalent to 1,863 USD in 2007.) The cheapest model of a 12-inch (30 cm) television is $ 445 (equivalent to $ 6,633 per 2007). 

Approximately 19,000 units of electronic television were produced in Britain, 1,600 units in Germany, and 8,000 units in America, [28] before the War Production Board was finally forced to stop TV production in April 1942 due to the outbreak of World War II.

TV use in the United States recovered after World War II after TV production was allowed back in August 1945. After the war, the number of TV owners in America increased by about 0.5% in 1946, up 55.7% in 1954, and up to 90% in 1962. [29] In Britain, the number of TV owners increased from 15,000 in 1947, then 1.4 million in 1952, to 15.1 million in 1968. Biography of John Logie Baird John Logie Baird (born in Helensburgh, Scotland, 13 August 1888 - died in Bexhill-on-Sea, East Suss3x, England, June 14, 1946 at the age of 57) was the first inventor to show that visual imagery can be transmitted.

Until he was 35 years old, Baird lived in a state of deprivation. In 1923, he began trying to tinker with the machine to transmit images, as well as sounds, over the radio. Shortly afterwards he managed to send a rough image through a non-wired transmitter to a receiver receiver a few meters away. In January 1925 he demonstrated television publicly at the Royal Institute in London. This is the earliest television show. 

In 1929, the BBC made its first television broadcast, using Baird's equipment. But he did not use the use of Cathode-ray tubes, which became the basis of modern television. So the artificial system was unable to compete with the new system in 1933. (From Wikipedia, the free encyclopedia)
