Who Invented Television? Interesting Facts related to Television

There are many things that people often do when the holidays come. Some may choose to take a walk, some may decide to stay at home. He relaxes with family and enjoys watching TV. Time and again, this electronic device has indeed become one of the most enjoyable entertainment media. The reason for this is that we get to see many programs from movies to news on TV. But have you wondered who invented the television? (Who Invented Television in Hindi).

Today we are taking so much advantage of the invention of television, so we have to thank the inventor of television. Today in this post I will tell that Television Ka avishkar kisne kiya tha. And I will talk about the story of the invention of television. Not only one scientist has a hand in the discovery of TV, but many scientists have contributed for it. So let’s get started.

Television was first invented by John Logie Baird in 1925. JL Bared named his invention The Television was kept. In January 1925 Baird publicly demonstrated his invention of the television at the Royal Institute in London. He had published the image of a puppet named Sticky on TV. This is the first television show. In 1929, the BBC or British Broadcasting Corporation channel premiered its television broadcasts using Baird’s equipment. John Logie Baird was a Scottish engineer born on August 13, 1888. He was the first person who was able to broadcast moving images on television. Baird studied at Larchfield Academy, the Royal Technical College and the University of Glasgow.

After John invented the first mechanical television in 1925, Philo T. Farnsworth, a scientist from Utah, United States, developed the first modern electronic television at the age of 21 in 1927. Philo Taylor Farnsworth was an American inventor who is best remembered for inventing the first true electronic television system, which included the first functional electronic image reception device (video camera tube). But at that time they did not make use of the cathode-ray tube which is the basis of modern television. Then in 1929 Vladimir Zvorkin of Russia perfected the cathode tube called Kinescope, and the invention later developed the cathode ray tube technology.

After that, to fulfill the need of Color TV among the people, in 1938, German engineer Werner Flechsig created Shadow Mask Color TV. After this, till 1939, more people used different technology and invented television. But until this time television had not been publicly sold. Thus in 1939 the manufacturing of the first TV was started by DuMont Company. After that, by 1946, the DuMont Company’s network had become the world’s first TV network. This network was originally established to sell TV sets.

This CBA scientist built the first mechanical color television, following John Logie Baird’s theory on instructions from Peter Gollmark. Subsequently, in 1948 more than a million TVs were sold in the United States.

Today’s television is not the same as before. There was a lot of improvement in Television by using new technology every day. variety in the market today LCD, LED, OLED Like high quality TVs are available.

J. Ale. Baird is known as the inventor of the television. Baird’s first design was an electronic device called the Niepko disc, then the scanning disc was developed by German scientist Paul Nieppo in 1884. Then Baird worked on the idea of ​​NEEPCO, he developed a system with signals that could be sent via wireless electromagnetic waves. During the development phase, Baird lacked financial support, as most investors did not support Baird’s idea.

Until the age of 35, Baird lived in poverty. During this time Baird worked as a shoe salesman. Which was enough only to pay for food, shelter and mechanical equipment. Then in 1923, Baird began trying again to study machines for transmitting images, over the radio. He then managed to send a rough image over a wireless transmitter to a receiver a few meters away. Then Baird became famous overnight, and soon investors gave him enough capital to realize more complex goals. In 1927, he managed to send a television signal from London to Glasgow. Then John Logie Baird was listed as the inventor of the first television.

History of the development of television

The laws of electromagnetic waves, discovered in 1831 by Joseph Henry and Michael Faraday, form the historical basis for the invention of television, marking the beginning of the era of electronic communication, and the rapid development of television until now. Here’s a history of the evolution of television from year to year.

1876In The selenium camera was invented by George Carey, whose task was to observe electrical waves. Eugen Goldstein also called cathode rays shot of light waves in a vacuum tube.

1884 In , German scientist Paul Nipkow managed to send electronic images using a metal bar called an electric telescope.

1888 In , Freedrich Renitezer, an Austrian botanist, discovered liquid crystals, which later became the raw material for making LCDs.

1897 In , The first cathode ray tube (CRT) was invented by German scientist Karl Ferdinand Braun. He created a cathode ray tube with a luminous screen.

1900 In , Konstantin Perskile presented television at the First International Congress of Electricity at the Technology Exhibition in France.

1907 In , Campbell Swinton used cathode rays to send images.

1925 In , John Logie Baird invented the first mechanical television.

1927 In , Utah, USA scientist Philo t Farnsworth developed the first modern television at the age of 21, and his ideas on the Image Dissection Tube were the basis for television work.

1929 In , Vladimir Zvorkin of Russia perfected the cathode tube called the Kanescope, and the invention later developed the cathode ray tube technology.

1938 In – German engineer Werner Flechsig created Shadow Mask Color TV.

1940 In , Peter Goldmark created the field sequential color technology based on the Ritating Wheel and created the color television. This Rotating Wheel emitted three colors, Red, Blue, Green.

1958 In , Dr. A scientific paper on LCD by Glen Brown first published as a demonstration.

1964 In , The first Single Cell Prototype Plasma Television Display was created by Donald Bitzer and Jean Slotto.

1967 In , James Ferragson invented the Twisted nematic technique, and created a more practical LCD screen.

1968 In , LCD screens were first introduced by Root cause analysis.

1975 In , Larry Weber of the University of Illinois began designing color plasma screens.

1979 In , Scientists from the Kodak company succeeded in creating a new type of Organic Light Emitting Diode (OLED) display. Since then, they have continued to develop types of OLED televisions. Meanwhile, Walter Spear and Peter le Comber demonstrated LCD colors from light thin film transfer.

1987 In , CODEC patented the invention of OLED as the first display device.

1995 In , Larry Weber researched for decades and finally completed his plasma screen project, then Weber did the research with an investment of US$26 million from the Matsushita Company.

This was history only up to the 2000s. Since then, LCD, LED, OLED, Plasma and CRT Panel have been manufactured using different types of technology.

Types of TV in Hindi

Based on technology, there are 5 types of TVs available in the market today. So let’s know about all.

Types of Television

1. CRT TV

The full form of CRT is Cathode Ray Tube. For example, we can watch heavy TV of old times. CRT TV is still available in many homes. The box of this type of TV consists of a screen and a projector gun. An image is made by ejecting electrons through this ‘Projector Gun’ on the screen.

2. LCD TV

The full form of LCD is Liquid Crystal Display. It is a thin display used in laptops, desktops and TVs. The panel of LCD TV is filled with liquid crystal. LCD TVs do not emit light themselves, but a light source is needed to make an image on it.

3. LED TV

The full form of LED is Light Emitting Diode. This is not a new format, but it is an updated version of LCD TV itself. The same technology is used in LED TV as it is used in LCD TV. But the only difference here is that the LED does not require a fluorescent bulb like an LCD to light up, but the LED is lit by a series of Light Emitting Diodes.

4. Plasma TV

Plasma screens are made of 2 sheets of glass, with a mixture of gases between the layers. While making this type of TV, gas is injected and sealed in the form of plasma. That’s why it was called Plasma TV.

When electricity is passed through it, the gases react and produce light in pixels across the screen.

5. OLED TV

The full form of OLED is organic light-emitting diode. No external light source is required to illuminate them. This screen is very thin and can also be flexible. Brightness contrast of this TV is very good.

Although this TV is a bit expensive right now but due to the development of new technology, it is expected to be cheaper too. Apart from TV, this technology is also used on computer monitor, laptop and mobile screen.
