The television history allows to realize an apparatus that conceptualizes the distance vision, which managed to revolutionize the media, several few and even the way we interact.


Origins of television

With the invention of nipkow disk from Paul Nipkow there was a breakthrough for the creation of the device. With this an important change was achieved to attract television as we know it, thanks to the invention of the iconoscope from Vladimir Zvorykin Y Philo Taylor Farnsworth. With these previous steps the elaboration of a completely electronic television was achieved, which had a much better refresh rate, a greater definition of its image and its own lighting.

Summary of the history of television

In principle, the television history shows us that we opted for several mechanical solutions such as nipkow disk in 1884, but this type of mechanical system was soon discarded to give priority to fully electronic collection systems.

During the year 1925 with the Scottish inventor John Logie Baird, it was possible to carry out the first experience with two discs, one for the sender and the other for the receiver, which were attached to the same axis so that the turn was synchronous and separated by 2 mm.

An important date is the year of 1927, where the electronic television born thanks to the 21 year old Philo Farnsworth, who can decompose an image into 60 lines of light, to transmit them as electrons and recompose the original image on a screen.

TV evolution

According to the television evolution Several and several steps were taken to consolidate the models we know today. Actually, there were many developments.

Baird TV

The television created in 1920 by John Logie Baird It supposed what we know today as television, but it was not totally electric since it had a mechanical component. His box was very large and the screen very small.

First electronic television (black and white)

By 1930 the size of the screen increases and decreases in the box it contains. In this case it is totally electric. During the war the rise of television diminish, but progress was made in its technology.

In 1948 at the end of the war, a model in full economic recovery goes on sale, which even made television become an appliance for everyone.

Television on the RCA 21 model

It was an invention of 1950 and it was a model that meant a significant change. It was a television much more similar to the televisions that happened to him and that also has the bases that exist today.

color television

During 1940 the Mexican Guillermo Gonzlez Camarena was the one who created a system for the transmission of color television, opting for a sequential trichromatic system of fields. In 1960 there was a great revolution as it went from the black and white transmission to the color transmission.

Television with cathode ray tube (CRT)

The television with cathode ray tubes better its definition, the size of the screen grew and the resolution became larger by the amount of pixels per unit of surface present. It was a key step for the consolidation of television as it is known today.
