Our world has undergone significant development in terms of technology. The technology that we see most often and most often we use is the alias television TV. Tele (derived from the Greek, meaning far) and Visio (derived from Latin, meaning far or vision) are the words forming on television. Television comes in response to the weakness of the radio. In addition to audio sound, visual or included with the television images that live and move, which makes people more like television than with other telecommunications.
Reporting from Komunikasius, Thursday (09/04/2015), the beginning of the creation of television starting from the discovery of Electromagnetic Waves by scientist Joseph Henry and Michael Faraday in 1831, and the discovery of liquid crystals by Friedrich Reinitzeer and Ray Tube Katroda by Karl Ferdinand Braun. Television term was first used by Russian leaders Constatin Perskyl in 1900 in the International Congress of Electricity. Prominent Russian, Vladimir Zworyki, in 1929 Katroda Tubes enhance and create CRT findings. Then, in 1940, a character named Peter Goldmark find a color TV for the first time with a resolution of 343 lines. After World War II ended, the world community began to enjoy television. In the 1950s, television began to mushroom and become the people's choice, which still mainly black and white, although color television was already there at that time.
Then, in about 1968, LCD screen television was introduced by a body called the RCA chaired by George Heilmeier. In 1995 the American character named Larry Webber also creates a plasma screen, which in that year was stronger than other types of televisions. Entering the 2000s all kinds of enhanced television and doing various forms of refinement, both on the LCD, Plasma, and CRT.
TV experienced rapid development since it first appeared. At first appeared analog TV based on the frequency and the signal, which is based on NTSC, PAL and SECAM. Then came digital TV as part of the development of this technology. Digital TV quickly surpassed analog TV and quickly spread also among the community. The major difference between analog TV and digital TV reception is at the image through a transmitter, signal processing and its appliances. Digital TV is based on LCD, LED and OLED, although TV tubes can still be used. Digital TV uses DSTB system or Digital Set Top Box, which allows to convert the digital signals into sound and pictures we see on the TV screen. Advantages of digital TV than analog TV is more efficient in energy use and the reduction of noise and a lot more channels provided.
Perhaps you too have felt using a CRT TV or a TV tube. TV This type is popular around the 1970s until the late 1990s, as only this type available at that moment. Entering the 2000s, the use of LCD TVs start to bloom. In fact, now the LCD TV has begun rarely used because so many have switched to LED TVs. The working principle of LCD TVs using water crystals to create the image, which is then converted or convertible into view. In order to perform, takes the light from behind the screen called fluorescent backlight or Backlight fluorescent lamps, which serangkaiannya technology called CCFLs (Cold Cathode Lamps Flurescent). Meanwhile, TV LED (Light Emitting Diode) has the same working principle with LCD TVs, the difference is only in the LED TV uses LED lights to replace fluorescent. While on TV LED (Organic Light Emitting Diode) based on semiconductors that are used as light-emitting layers made of organic.
In addition to the three types of television, there is also a Plasma TV Merk LG. Plasma TV is the development of flat-screen TVs and high-resolution plasma called for exactly the way it works that use plasma or a gas that is able to separate the electron from the atomic nucleus and create an image. Colors in the Plasma TV is determined by phosphorous gas which is based on RGB color. Hanysa there that say that this Plasma TV is quite wasteful electricity.
Television is going to strive with all effort to not lose the internet. And it was, the television will not disappear in a short time. People more and more creative and find new innovations, and innovations on TV hopefully remain so its existence is still there until subsequent years.
