Before I write any further development of the television world, then it would be nice if this blog I am also content with writing about the history of invention and innovation in the world of television. I compile this material from various sources, including Wikipedia.
The word television comes from the words "tele" and "vision", which means each remote (tele) and looks (vision). So television is visible or can be seen from a distance. The discovery of television juxtaposed with the invention of the wheel, because the invention is capable of changing the world civilization. In Indonesia, 'television' is not formally called the TV, television, television or tipi.
In the discovery of television, there are many parties, inventors and innovators who are involved, both individuals and companies. Television is a mass work developed from year to year.
The beginning of television certainly can not be separated from the basic invention, namely Electromagnetic Waves law discovered by Joseph Henry and Michael Faraday (1831) which is the beginning of the era of electronic communication.
1876 - George Carey described creating Selenium Camera can make someone see the electric wave. Later, Eugen Goldstein called the shots light waves in vacuum tubes was named as the Cathode Rays.
1884 - Paul Nipkov, German scientist, managed to send an electronic image using a piece of metal called a telescope with a resolution of 18 line Electric.
1888 - Freidrich Reinitzeer, Austrian botanist, discovered liquid crystals (liquid crystals), which later became the raw material for the manufacture of LCDs. But the new LCD screen was developed as 60 years later.
1897 - Cathode Ray Tube (CRT) was first invented by a German scientist, Karl Ferdinand Braun. He made the CRT screen with fluorescent when exposed to light. This is the embryo of the screen tube television.
1900 - The term was first put forward Constatin Television Perskyl from Russia at the International Congress of Electricity is first in the World Technology Exhibition in Paris.
1907 - Campbell Swinton and Boris Rosing in separate experiments using cathode rays to send pictures.
1927 - Philo T Farnsworth scientists from Utah, the United States developed the first modern television at the age of 21. The idea of the image dissector tube is the basis for television work.
1923 - Vladimir Zworykin Kozma, registering patents in his name for his invention, kinescope, the world's first television tubes. A year later, he received United States citizenship and completed his doctoral studies at the University of Pittsburgh. Vladimir was born in Russia, 30 July 1889. He perfected the cathode tube called a kinescope. Her findings developed technology by CRT. He works at an electronics company RCA and during 1930 to the 1940s, the company was spoiled by draining funds of U.S. $ 150 million for the production of television technology. Zworykin openness to criticism, made him find a new discovery. A camera tube. It complements the television tube technology invention. The discovery was named iconoscope, derived from the Greek, which means the image icon and scope that is observed. He died of old age on July 29, 1982. It was he who later as the inventor of television. (1889-1982).
1939 - exact date of May 11, for the first time, a television transmitter operated in the city of Berlin, Germany. Thus, the world became acquainted with a visual communication tool. The television station later Nipko named as a tribute to Powell Nipkov, the famous German scientist and one of the inventors of television equipment.
1940 - Peter Goldmark created a color television with a resolution reaches 343 lines.1956 - Robert Adler was born in the United States along with fellow engineer Eugene Polley, find the remote control television. Although not a television, but his findings are very important for television technology. He died at the age of 93 years. Emmy award recipients since its discovery in 1997 that earned more than 180 U.S. patents during the 58-year career. According to his wife, television remote control was not the discovery of her favorite and she rarely watched television.
1958 - The first scientific paper on the LCD as a display screen presented by Dr. Glenn Brown.
1964 - Prototype of a single cell was first invented Plasma Television displays Donald Bitzer and Gene Slottow. This step is followed Larry Weber.
1967 - James Fergason invented Twisted Nematic, LCD screens are more practical.1968 - first introduced LCD screen RCA-led institution George Heilmeier.1975 - Larry Weber of the University of Illinois began designing the color plasma display.
1979 - Scientists from the Kodak company managed to create the appearance of new types of organic light emitting diode (OLED). Since then, they continue to develop the kind of OLED televisions. Meanwhile, Walter Spear and Peter Le Comber making LCD color display of materials in thin film light transfer.
1981 - Japanese broadcaster, NHK, demonstrate HDTV technology with a resolution of 1.125 line.
1987 - Kodak's patented OLED findings as display devices the first time.1995 - After decades of doing research, plasma screen project finally finished Larry Weber. He managed to create plasma screen a more stable and brilliant. Larry Weber then megadakan research with investment worth 26 million U.S. dollars from the company Matsushita.
The 2000s, each type of display technology is progressively completed. Both the LCD, Plasma and CRT continues to issue a final product that is more perfect than ever.
2008 onwards, following the development of digital television in the United States and Europe, Indonesia will also implement digital television broadcasting (Digital Television / DTV) is a type of TV that uses digital modulation and compression systems to distribute video, audio, and data signals into television set.
Background of the development of digital television:-Changes in the external environmentAnalog-TV market is already saturated-Complaints of noise, ghost etc.-Competition with satellite and cable broadcasting systems (Cable Television)
Technology development:Digital signal-processing technology (Digital Signal Processor)Digital-transmission technologySemiconductor-TechnologyTechnology-resolution display devices tingggi
The advantages of digital television:-High Definition. 5 ~ 6 times more subtle than analog television-Finest sound. The ability to reproduce sound as the original source-Multifunction. Provides the ability to record and edit broadcast-Multichannel (one channel can be charged more than 5 different programs)
Hopefully useful. Thank you.
