Who invented television?

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

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

In 1938, German engineer Werner Flechsig created shadow mask colour TV to meet the need for Color TV among the people. After this, by 1939, more people used different technologies and invented television. But by this time television was not sold in public. Thus, in 1939, the manufacturing of the first TV was started by the DuMont Company. 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 created the first mechanical colour television, forwarding John Logty Baird’s theory on the instructions of Peter Goldmark. After this, more than one million TVs were sold in the United States in 1948.

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

Brief information about the inventors of the Television

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

Until the age of 35, Baird remained in poverty. During this time Baird worked as a shoe seller. Which was enough only for the payment of food, shelter and mechanical equipment. Then in 1923, Baird again began trying to study machines to broadcast images, on the radio. He then managed to send a thick image on the wireless transmitter to a receiver a few metres away. Then Baird became famous overnight, and soon investors gave him enough capital to realize more complex goals. In 1927, he managed to send television signals from London to Glasgow. John Logie Baird was then 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, are the historical basis of the invention of television from which the era of electronic communication begins, and the development of television has continued rapidly so far. Here is the history of the development of television year after year.

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

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

In 1888 – An Austrian botanist, Friedrich renitezer, discovered liquid crystals, which later became the raw material for making LCD.

In 1897– the first cathode ray tube (CRT) was invented by German scientist Karl Ferdinand Braun. He made the cathode ray tube with a glossy screen.

In 1900 – Konstantin Perskile presented television at the first International Congress of Electricity at the Technology Exhibition held in France.

In 1907 – Campbell Swinton used cathode rays to send pictures.

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

In 1927 – Scientist Philo T. Farnsworth of Utah, USA, developed the first modern television at the age of 21, and his views on the Image Dissection Tube were the basis of television work.

In 1929 – Vladimir Zvorkin of Russia perfected the cathode tube called Kanescope, and the invention later developed the Cathode Ray Tube technique.

In 1938 – German engineer Werner Flechsig created a shadow mask colour TV.

In 1940 – Peter Goldmark created field sequential colour technology based on the Rating Wheel and created colour television. This rotating wheel is used to emit three colours, Red, Blue, and Green.

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

In 1964 – the first single-cell prototype plasma television display was created by Donald Bitzer and Jean Slotto.

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

In 1968 – LCD screens were first introduced by Root Cause Analysis.

In 1975 – Larry Weber of the University of Illinois began designing coloured plasma screens.

In 1979 – scientists from the Kodak company succeeded in creating a new type of Organic Light Emitting Diode (OLED) display. Since then, he has continued to develop types of OLED televisions. Meanwhile, Walter Spear and Peter le Comber displayed LCD colours from a lightly thin film transfer.

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

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

It was only history until the 2000s. Since then LCD, LED, OLED, Plasma and CRT Panels have been made using a variety of technologies.

Types of Television

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

1. CRT TV

CRT stands for Cathode Ray Tube. For example, we can see the heavy TV of the old-fashioned. Crt TV is still seen in many homes. The box of this type of TV has a screen and a projector gun. An image is created by removing electrons through this ‘Projector Gun’ on the screen.

2. LCD TV

LCD stands for Liquid Crystal Display. It is a thin display that is used in laptops, desktops and TVs. The panel of the LCD TV is filled with liquid crystals. LCD TVs do not emit light on their own, but a light source is required to create an image on it.

3. LED TV

LED stands for Light Emitting Diode. This is not a new format, but it is an updated version of LCD TV. LED TVs also use the same technology as LCD TVs. 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 with a series of light emitting diodes.

4. Plasma TV

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

When electricity is flown into it, the gases react and generate light in pixels across the screen.

5. OLED TV

OLED stands for Organic Light-Emitting Diode. They do not require an external light source to light them. This screen is very thin and can be flexible. The brightness contrast of this TV is much better.

Although this TV is a bit expensive right now, the development of new technology is expected to make it cheaper as well. Apart from TVs, this technology is also used on computer monitors, laptops and mobile screens.
