World Television Day: The Journey From B&W to OLED

American scientist John Logie Baird invented the television in 1927. For almost 7 years, the attempt to give TV an electronic form went on and finally in the year 1934 it came in completely electronic form. Within 2 years, many modern TV stations were opened. Gradually it became an important part of entertainment and news. In 1996, the United Nation, seeing television growing in common life, declared November 21, 1996 to be celebrated as World Television Day.

 

On the occasion of World Television Day, today we will talk about the idea of ​​bringing you a TV, the journey from black and white, color TV to smart TV. Along with this, we will also tell about the changes in the display of the TV. So let’s start…

 

Telegraph cable repair worker brought the idea of ​​television

 

British telegraph worker Joseph was working on the transatlantic telegraph cable in 1872. He observed that some changes were visible in the electrical conductivity of the selenium wire. When he tried to find out the reason for this, it was found that this is happening due to the sunlight coming from the window falling on the selenium wire. It was from this incident that the basis for converting light into an electric signal was prepared.

 

In 1880, a French engineer named Maurice La Blanca published an article in the journal La Lumiere Electric, which laid the foundation for all subsequent televisions. La Blanca proposed a scanning mechanism. However, they were not able to produce any working machine.

 

Paul Nipkov, then a German engineer, was the one who took television to the next level and discovered the scanning disc. The device that Nipkov devised helped send pictures over a wire from a rotating metal disc. Nipkov named it ‘Electric Telescope’.

 

The term television was first used by Russian scientist Konstantin Persky at the 1900 Paris Exhibition. Scottish inventor John Logie Baird and American inventor Charles Francis Jenkins had achieved great achievements by introducing mechanical TVs. The devices that both of them made are considered to be the first successful televisions.

 

In 1922, Jenkins sent a static image to the screen via radio waves, in 1925 Baird sent a live transmission of a human face.

In 1925, the inventor Vladimir Zworykin told about the color TV system. However, this system did not succeed. The world’s first electronic television was created by an inventor named Philo Taylor Farnsworth. The device built by Philo was successful in capturing the moving image with the help of an electron beam.

 

 

 

The first commercial appeared on Charles Jenkins’ television program in 1930, and the BBC began regular TV transmissions.

By 1934, all mechanical TVs had come to electronic systems, and there is no doubt that primary television footage could be transmitted in black and white.

 

Talking about color TV, it was patented in 1904 by a German inventor. Although the inventor did not have a color television.

 

Television was shown at many fairs across America in 1939–40. Some models also came with a radio, so that audio could be heard along with the pictures on the screen.

In 1950, two big companies CBS (Columbia Broadcasting System) and RCA (Radio Corporation of America) competed to make the first color television. In this battle, CBS won and made the first color television set. The device was a mechanical television based on

 

John Baird’s system.

It was in 1950 that the first remote was made by Zenith Radio Corporation, which connected a wire to the TV. The wireless remote was developed by Eugene Pauli in 1955.

In 1951, an American broadcasting company named CBS ran the first commercial color TV program. Due to being a black and white TV at that time, only 12 customers were able to

 

The premiere of Walt Disney’s wonderful ‘World of Colour’ in September 1961 proved to be a turning point and inspired people to switch to color TV.

 

In 1965, a 1 hour daily service was started in the country with a news bulletin.

In the 1960s and 1970s, television broadcasting stations and networks in most regions

 

World upgraded from black and white TV to color transmission.

In 1968, the Japanese television network NHK began creating a new television standard, which later became known as High Definition Television, or HDTV.

In 1975-76, television programs were started for 1 year under the Satellite Instructional Television Experiment for the people of 2400 very underdeveloped and remote villages of the country.
