What is TV and what were the preconditions of its appearance
From the point of view of science TV set - a receiver of certain electrical signals, equipped with a screen and speakers to quickly display successive images and sound. Personal appearance and component parts of the device, we will not talk in detail, since only the most orthodox adversaries of science does not know what it looks like a TV.
As with all electronic equipment, such devices did not appear at once: it was preceded by a whole galaxy discoveries.
More at the primitive society, our ancestors tried to depict movement in rock paintings
The most important inventions contributed to the development of the device are:
| An object | year opened | Appearance |
| The photo | 1822 | |
| speaker | 1877 | |
| camera | 1885 | |
| Radio | 1895 |
Who invented television -Examine the process step by step
So, progress gradually led us to the first half of the XX century, when all available at the time of use were gradually transformed into something completely new - it began to appear very first in the world televisions. And it was so ...
When was invented and what made the first mechanical TV
The starting point of reference the history of television we can safely assume 1884. It was then that an engineer from Germany, Paul Nipkow invented a special device called "Nipkow disk". The essence of the invention is as follows: on the plate round shape applied in the order specified holes. Light passing through the holes, passed information through the receiver and the image appears on the screen.
Manual processing of data takes a lot of time and resources
This development has decided to develop a Scottish businessman John Baird, founder of Baird. In the mid 1920s he was able to optimize the image display system so that all the details are displayed clearly as possible, and the movements look smoother. Thanks to his diligence was Byrd was considered those who invented the mechanical television.
Up until the mid-1930s, the corporation Baird production was virtually a monopoly in the television market.
Samples device manufactured by Baird is a structure shaped like a wardrobe or dressing. Inside it has a set of Nipkow disk and a light projector, and could be seen in front of the small screen.

In 1928, the industrial giant General Electric has released an experimental model of mechanical TV called «Octagon» in the United States. This engineering marvel not fall into the mass access, remained a prototype for further improvements.
When and how did the first electronic TV: effective improvement
As time went on, and the next round of evolution was able to further improve all parameters of TV equipment. Parallel to the invention the mechanical TV models, Scientists have tried to "tame" the electricity to increase the signal processing speed and quality of the final image. This discovery contributed to Heinrich Hertz so-called photoelectric effect, as well as the appearance of a phosphor - specific substances that emit light under influence of an electric current.
The phosphors are not only used in televisions - the sphere of advertising and design actively uses glowing particles
Combining these inventions in their experiments, the talented German physicist Karl Braun invented in 1897. The first CRT (cathode ray tube). Following the baton of grabbed Russian scientist Boris Rosing, who established in 1907 the above-mentioned CRT in a closed housing. Alas, even as revolutionary for the time experiments did not find interest and widespread.
If the school of physics you had solid five, with the principle of the CRT is not difficult to understand
Do you know what year finally has its first full-fledged electronic TV? Only in 1936! That's when Russian immigrant Vladimir Zworykin (a disciple of that same Boris Rosing) in the United States under the auspices of of Radio Corporation of America (RCA) held the release of the first prototype products for private use. A massive production acquired only in 1939 with the introduction of the RCS TT-5. This black-and-white TV was very cumbersome, and the screen size at the receiver was only 5 inches.
It is difficult to imagine, but many of today's smartphones have a much larger diagonal and resolution than a creation of scientific genius

Despite the fact that electronic technology at the turn of the third millennium, developed by leaps and bounds, the progress in the field of television in the first half of the XX century was not so noticeable. Just think: a patent for an electronic television inventor Zworykin was back in 1923, and then the first copy was developed 13 years.
When the first color TV
By the early 1950s, the era of mechanical television came to a logical end, completely giving way to a promising electronic device. Engineers are constantly inventing improvements, reducing the weight of the product and improving the image quality. One of the major drawbacks of television at the time was the lack of color (other than black and white, and shades). Despite the developments mentioned contact Baird and Zworykin (1928), the first attempt to make a color image was made only in 1940 - in the form of American television "Triniskop" system. Alas, history has not preserved the exact names of those who invented and implemented a color television at a time... A full-featured and accessible to all version saw the light only in 1954 - through the efforts of the famed RCA.
The first unit of the Radio Corporation of America wore RCA CT-100 name
Who invented the flat screen TV: forward to progress!
The next step in the improvement of television receivers was the decrease of the kinescope and, as a consequence, reduce product thickness. plasma and LCD screens - two areas where you can allocate.
The first television based on "plasma" was developed back in 1964 by Americans Donald Bitzer and Gin Slottou, but their physical incarnation of the world saw only in the 80s. Despite the tremendous picture quality of the resulting electricity effects on ionized gas (plasma), the high cost and competition has forced manufacturers across the globe in 2014 to stop the production of these panels.
One of the first mass of samples used computer companies, for example, the IBM
Palm belongs to Japanese company Casio among the creators of liquid crystal TVs - their creations left the assembly line in 1983. Since then, much water has flowed, TFT technology has given way to a more economical and bright IPS. However, both standards today are the most popular and in demand.
In the most modern devices used OLED and AMOLED - luminescent LEDs
Who created the first television in the USSR
The Soviet Union could not bear to look at the development of the western countries, leaving such a powerful source of development of science and advocacy. But how the process of creating a television in the Soviet Union? When the Soviet Union there was a color TV? Editorial Tehno.guru ready to respond and to these difficult questions.
In which year the Soviet Union developed the first black and white TV
Full production of standard domestic television mechanical modifications were initiated in our country only in 1932 the forces of St. Petersburg "Comintern" plant. By 1938, the company has established the same issue of the TC-1 model, more advanced and powerful. In spring 1939 the Federal Republic began permanent broadcasting.
KVN-49 became the first electronic television in the USSR. In some families, like antiques it is still working - able to do!
When the Soviet Union came the first color TV
Soviet citizens also wanted to observe what is happening on the screen in all colors. But the way of color television in the territory of present-day Russia and the CIS countries was thorny and complicated. The first Soviet color television appeared only in 1954 through the efforts of the same "Comintern", a model called "Rainbow." In the future, such products as "Ruby-401" and "Record-101" could be the most accessible and popular representatives of a class.
It thus seemed a family watching a movie on the screen in 1954, a brand new "Rainbow"
Summary: Now you know who came up with the TV!
So, here we have passed and the entire chain of progress in the creation of television. You could watch the great inventions of the XIX century, complex investigations beginning of the XX century, changes in information processing technology from mechanics to electrical engineering, learned, when the color TVs in the USSR. To date, our editorial mission accomplished - we sincerely wish you a pleasant watching your favorite movies and programs.
