Progression Of Televisions From Mono Chromatic Dinosaurs To Sleek Hybrids
March 15th, 2011 | Author: admin
TVs have come a long way from the old huge black and white set to the latest sleek 3 D models. They have become an integral part of the drawing rooms all over the world. The television, which was once considered a luxury, is now a need. Almost 90 years after its invention, the television has truly come of age.
The birth of television was laid back in 1897 by Karl Braun, a German scientist, who invented the cathode ray tube oscilloscope. The first working television was invented by the John Logie Baird in 1922. He used an array of transparent rods to transmit images. His model of television was based on the principles of scanning and image transmission discovered by Paul Nipkow. This was the first model that showed pictures by reflecting light.
From then on, there was a continuous development in the modernization of the television. The TVs in 1930′s were a huge block though the effective screen size only amounting to a measly 25% of the total box area. After this, the first live telecast also followed suit, which was monochromatic. The colored television came into picture a decade and a half later.
In 1956, for the first time, remote control was released in to the market. It was dubbed “Lazy Bones”. Once only affordable by the rich and wealthy, televisions came within a middle class man’s reach soon after the second world war and continue to be an appliance that holds a lot of value in today’s fast paced life.
The invention of the flat screen televisions was done much later. It was Donald Bitzer, Gene Slottow and Robert Willson who developed plasma technology in 1964, and designed a plasma display monitor for the first time.
The old box models with a transmission picture cathode ray tube and an antenna are long gone. The latest high definition LED and LCD televisions use liquid crystals for transmission. The picture quality is perfect and very real. Plasma televisions have gone even further. They use plasma cells, which are a mix of inert gases and a bit of mercury. The images in plasma televisions are better than the LCDs. 3D televisions are now the new rage. This enables the user to experience 3D viewing without wearing special goggles. The first 3D serial telecast happened in 2009.
With the ongoing development, we can expect the interactive TVs and the latest models of digital television shortly. Only time can reveal what technology has in store.
