TV technologyImage viewer and voice box has been found from many years ago and involved various parties, whether individuals or institutions. Also involves many experts inventors, and inventors can not be separated from the basic laws of electromagnetic waves, Joseph Henry and Michael Faraday. In GPS application like Magellan eXplorist 500, this basic law is used to transfer signals from satellites to receiver so we can get our positions on earth. This sophisticated box viewer use varieties of technology such as CRT, LCD, Plasma, DLP, and OLED. Half mounted projector is also considered a television tuning. There are two types of television. One is an analogue television and digital television. By encode analogue television picture information by varying the voltage and / or frequency of their signal.

The entire system can be inserted before the digital TV to analogue. And at the end of the year 2009 has been a lot of countries that have turned off the television system. The first country to shut down this system off is Luxembourg in 2006. Digital television is television that uses digital modulation and compression to broadcast video signal, voice, and data to the television. Digital television is a tool used to capture digital TV broadcasting, the development of analogue to digital broadcast system that converts the information into digital signal data bits shaped like a computer.

Television is a broadcast picture tentacle. The word television comes from the words “tele” and “vision”, which means each distance (tele) and looks (vision). So television means visible or can be seen from a distance. In the discovery a lot of inventors are involved. Beginning from the television would not be separated from the basic discovery, law of electromagnetic waves discovered by Joseph Henry and Michael Faraday (1831), which is the beginning of the era of electronic communication.

Development of the invention begins with creating a television camera selenium can cause a person described seeing waves of electricity. And the term first appeared on television in 1900 put forward by Constatin Perskyl fromRussiaat the International Congress of Electricity. After tens of years doing research, plasma screen project finally finished Larry Weber. He succeeded in creating a more stable plasma screen and brilliant. Finally, in the decade 2000, each type of screen technology more and more refined.

Both the LCD Plasma and CRT continues to give final products are more perfect than ever. It is true that many peoples say that the resulting picture LCD and Plasma TVs have higher resolutions. But the weakness is the time or age of the TV can not live long if we wear them constantly when compared with CRT TV or what is known as a regular television that people use in general.
