Who does not know television. A well-known telecom media broadcast receiver to function as a moving image along with sound either monochrome (black and white) or color.
Television said compound of tele "far" from the Greek and visio "vision" of Latin. So that television can be interpreted as a means of distance communication which uses visual or visual media.
Television is paralleled with the invention of the wheel, because this discovery could change the world civilization and in Indonesia the television is often called the TV.
In the early days of its development, the television using the combined technology of optics, mechanics, and electronics for recording, viewing, and broadcasting visual images.
At least in the late 1920s, the television system using only optical and electronic technologies alone, where all modern television systems implementing this technology. However, now in the digital age with the times, large screen televisions or tube began to erode with technological developments.
Here are reviews about the development of the TV from time to time, ranging from TV to TV screens curved tube, as reported by Cnet Okezone searches, Monday (02/15/2016).
Tube TV or CRT TV (1990s)
CRT (cathode ray tube) or commonly known as tube TV has a diagonal screen size of approximately 40-50 inches, had the technology as used on the PC monitor. The tube has a high-speed flow of electrons emitted from the cathode to create the image.
The advantages of CRT, the lowest price compared to other TV types. TV endurance strength endurance Tubes have a very long, usually can last up to 3 years and above and the power of the screen is not in doubt.
Meanwhile, there are shortcomings in a very large body size and weight make the room more cramped. The electric power Power Consumption Average 75W ++.
Television output this time is the forerunner to the presence of modern TV types like Plasma TVs, LCD TVs, LED TVs and TV Curved.
Plasma TV (1997's)
Plasma TV is the earliest development of technology in the slim TV with high resolution and plasma name itself is basically adapted to its working principle.
Plasma itself means a gas that can separate electrons from atomic nuclei to produce images on a TV. More detailed incoming electric current will produce the electrons that will react with a molecule of mercury (mercury) and produces ultraviolet light (UV).
Plasma TV advantages compared to other TV is having a wider viewing angle and high contrast of 10,000: 1. In addition, Plasma TVs tend to be cheaper than LCD or LED.
In fact, it can take a great picture display does not blur as Plasma TV, has a level Refresh Rate and Response Time is high up to 600 Hz.
However, keep in mind that the current Plasma TVs tend to weigh more heavily because it is generally larger than 32 inches and wasteful of electrical energy.
LCD TV (2003's)
TV LCD (liquid crystal display) technology that uses an LCD to produce a picture, generally like those found on a PC monitor on the market today.
LCD technology is already used on the computer monitor. In addition, plasma technology has advantages of anti-glare or without shadows, more realistic colors.
But with lower power consumption than LCD TVs Plasma TVs causing suitable for use as a PC screen at home or in the office.
The fundamental weakness of the LCD can generally be felt when watching TV, especially in less space lighting. When compared with other types of TV, LCD TV will produce image quality and contrast less well when viewed from a wider angle.
